Microsoft vs. IBM: what is the enhanced inventory buy? | killexams.com actual Questions and Pass4sure dumps

each Microsoft (NASDAQ:MSFT) and IBM (NYSE:IBM) own needed to shift their strategies in recent years to preserve providing boom for shareholders. however, despite slowing pc income and competitors from Apple, Microsoft has had a ways improved success than IBM in maintaining its trade momentum going. Microsoft is customary for its dominance with its windows operating paraphernalia and workplace application, however over the ultimate two years, it has emerged as probably the most largest cloud suppliers on earth.

IBM is investing heavily within the cloud, too, however it's struggling to withhold up with quick-transforming into tech competitors, including Microsoft. Of course, the determination to purchase both of these stocks may soundless breathe based on more than simply who is growing faster within the cloud area. they will compare both organizations' fiscal positions, valuations, dividends, and most significantly, their competitive positions to check which is the superior buy today.

financial fortitude

A assessment of an organization's monetary fitness tells buyers greater than in basic terms which trade can hold up more desirable utter the passage through periods of softening in the fiscal system. a corporation with robust monetary fortitude has greater opportunities to convey returns to shareholders through constructing fresh items, making earnings-constructing acquisitions, or paying a rising dividend over time.

With that in intellect, here's a overview of how both organizations measure up on key monetary metrics: 

Metric Microsoft  IBM money $127.66 billion $12 billion Debt $73.17 billion $45.18 billion salary (TTM) $118.forty six billion $seventy nine.59 billion Free cash tide (TTM) $31.9 billion $11.fifty three billion Free cash circulation as a percentage of profits 26.9% 14.5%

records supply: YCharts. TTM = Trailing 12 months.

Microsoft is naturally the winner on this critical check. The application massive has about $54.5 billion of net cash, after subtracting debt, whereas IBM has extra debt than cash. 

Winner: Microsoft.

Valuation and dividends

a higher-buy assessment is never finished devoid of due to the fact that valuation. evaluating these two shares on quite a number universal metrics will serve grasp custody of against overpaying for an organization's profits. here's how shares of Microsoft and IBM stack up: 

Metric Microsoft IBM Trailing P/E 25.1 14.fifty one forward P/E 21.7 9.seventy four PEG ratio 1.seventy two 10.22 price-to-free money flow 26.four 10.97 Dividend yield 1.72% four.6% Dividend payout as a percentage of free money circulation 41.forty four% forty nine.14%

facts sources: YCharts and Yahoo! Finance.

at first glance, IBM looks just like the improved cost. however, withhold in mind, analysts await great Blue to develop profits by 1% per 12 months over the next 5 years, so the enterprise's low fee-to-revenue numerous may soundless embrace a warning label. even so, analysts are expecting Microsoft to develop revenue by means of 14% per yr going ahead -- that is why Microsoft has a lessen PEG (expense-to-profits-increase) ratio.

even so, any improvement in IBM's salary growth would probably trigger buyers to alter their expectations, which would send huge Blue's stock fee better. So, i'll provide IBM the capitalize of the doubt.

taking a examine at dividends, IBM seems just like the winner. It pays a juicy yield, which salary buyers should soundless find appealing. however once more, caution is warranted.

I lately made the controversy that Microsoft is a stronger dividend boom inventory than IBM, and that i'm sticking to it. IBM's succumb is tempting, but Microsoft has really grown its dividend at a sooner expense than IBM in recent years. in the meantime, IBM hasn't grown its free cash circulation, and except that turns around, future dividend increases should breathe arduous to approach by using.

I give IBM the facet on valuation, but i'm sticking with my cognomen that Microsoft is a much better dividend inventory. So, this one is a draw.

Winner: Tie.

competitive moat

Microsoft continues to bring tenacious consequences for shareholders stemming from its aggressive advantages, including community results, switching prices, and manufacturer. in the fiscal second quarter, income improved 12% year over year, pushed via 48% boom within the trade cloud business. in the cloud enterprise, Azure grew 76% for the 2nd consecutive quarter as organizations continue partnering with Microsoft for his or her cloud-computing wants, including Kroger, Mastercard, and Walgreens Boots Alliance.

moreover, the software giant's shift to a subscription-based mostly mannequin for workplace continues to supply solid effects. Microsoft now has 33.3 million subscribers to office 365. revenue from productiveness and enterprise approaches (including workplace 365, Dynamics 365, and LinkedIn) grew 13% year over yr within the remaining quarter.

Microsoft has one of the precise manufacturers on the planet, which is because of the the familiarity thousands and thousands of people and corporations own with home windows and workplace application. The company is nascence to leverage that technological expertise and brand awareness in other pleasing areas, together with internet of things, simulated intelligence, and combined truth, besides cloud-computing. 

On the different side, IBM has been serving company shoppers for years. massive Blue has huge competencies in consulting organizations throughout many industries to aid them compete more simply. 

IBM's main rigor is finding boom. while IBM isn't going anywhere, it's additionally now not more likely to grow lots within the next few years. About half of IBM's enterprise is caught in sluggish-starting to breathe markets like legacy IT features, hardware, and utility features. 

youngsters, as that you can descry with Microsoft's contemporaneous boom, cloud spending is where utter the motion is. IT spending is present process a massive to shift to the cloud, which would not play to IBM's strengths. while IBM noticed its cloud enterprise develop 12% ultimate 12 months, that's peanuts compared to Microsoft's augment within the cloud. IBM's cloud market share is ready 2%, while Microsoft noticed its share bounce from 8.7% in 2016 to 13.3% in 2017. 

Amazon.com and Microsoft are absorbing many of the cloud spending privilege now. IBM's contemporaneous acquisition of red Hat will assist, but normal, Microsoft is in a tons enhanced aggressive position.  

Winner: Microsoft.

Microsoft is the better purchase

IBM could breathe a fine contrarian guess, mainly if the enterprise begins to disclose signs of growth once more. but for now, i would fairly retreat with consistency. Microsoft has the fiscal fortitude, increase, and competitive advantages that beget the king of utility a no brainer settle on.

    Software automates Java GUI testing. | killexams.com actual questions and Pass4sure dumps

    Press Release Summary:

    Based on WindowTester technology, WindowTester(TM) Pro v2.0 Eclipse-based software development tool streamlines testing of Java client applications, facilitating creation of consistent and dependable user interfaces. Supporting automated GUI testing for both swing and SWT frameworks, software is compatible with Microsoft Windows and Linux (GTK) and installs into any Eclipse-based development environment and automated build systems like Ant, Cruise Control, or Maven.

    Original Press Release: Instantiations WindowTester Pro Automates Java GUI Testing

    Eclipse-based tool virtually eliminates hand-coding GUI tests for celebrated Java swing and SWT frameworks

    SANTA CLARA, Calif., March 6 / -- EclipseCon 2007 -- Instantiations, Inc., a leading provider of software property and productivity solutions, today announced the release of WindowTester(TM) Pro 2.0. An Eclipse-based software development product, the fresh product streamlines the testing of Java client applications making it easier to create richer, more consistent and dependable user interfaces. The fresh product is based on the market-proven WindowTester technology contained in Instantiations' RCP Developer.

    As software development cycles shrink from months to weeks, automated, dependable GUI testing becomes increasingly necessary to meet customer expectations and software property goals. Manual GUI testing is time-consuming, labor-intensive and expensive and is usually left until the conclude of the development process. Manual testing depends on individuals following a set of involved directions, making the results incompatible and often unrepeatable. Finding software "bugs" late in the development cycle is no longer a choice. It delays product rollout and increases the cost of enterprise and shrink- wrapped software products.

    "Since they started using WindowTester, tests that took 2-3 weeks to write previously can now breathe done in 2-3 days," said Steve Tocco, director of property assurance Workshop unit at BEA Systems.

    "Developers resist GUI testing because it's complex, time-consuming and diffuses their focus on product development," said Dan Rubel, chief technology officer, Instantiations, Inc. "WindowTester reduces both the testing complexity and time needed. And it frees them to build property applications because it automates recording, test generation, code coverage and playback of GUI to application interactions rather than requiring time-consuming, hand- crafted and high-maintenance test code."

    "In terms of their investment in the WindowTester tool, they believe the cost of the licensing is greatly worth the enhancement and efficiency gained so far," said Bill Roth, vice president Workshop unit, BEA Systems.

    The WindowTester approach is based on the JUnit touchstone so it takes advantage of the indigenous Eclipse test framework. By offering greater flexibility in test development, maintenance and access to Java code, WindowTester is superior to existing alternatives, such as Abbot or the Eclipse Test and Performance Tools Platform (TPTP) that only support a unique Java platform. WindowTester Pro supports Microsoft Windows, Linux (GTK) and installs easily into any Eclipse-based development environment. It's equally easy to integrate with automated build systems like Ant, Cruise Control or Maven.

    "WindowTester Pro operates similarly to the window testing office in RCP Developer that their customers are chummy with," said Rubel. "However, WindowTester Pro supports automated GUI testing for both celebrated Java GUI frameworks, swing and SWT, and promises to breathe a more complete Eclipse GUI testing environment for enterprises."

    Price and Availability

    WindowTester Pro 2.0 is available immediately and in several configurations to meet different customer needs. For users who prefer more flexibility or a lower initial investment, the company offers a per developer subscription expense of $319 (USD) a year for the WindowTester Tools Library(TM). The yearly subscription provides access to utter the product tools available in the library -- including WindowTester Pro, WindowTester SWT and WindowTester swing -- as well as upgrades and technical support.

    For users who prefer a touchstone software license agreement, Instantiations offers WindowTester Pro separately for $799 (USD) per seat license. WindowTester SWT and WindowTester swing are each available separately for a $499 (USD) per seat license. Annual support for these products costs 25 percent of the first year's price.

    Drug repurposing: progress, challenges and recommendations | killexams.com actual questions and Pass4sure dumps

    Typically, a drug repurposing strategy consists of three steps before taking the candidate drug further through the development pipeline: identification of a candidate molecule for a given indication (hypothesis generation); mechanistic assessment of the drug consequence in preclinical models; and evaluation of efficacy in side II clinical trials (assuming there is enough safety data from side I studies undertaken as allotment of the original indication). Of these three steps, step 1 — the identification of the privilege drug for an indication of interest with a elevated level of self-confidence — is critical, and this is where modern approaches for hypothesis generation could breathe most useful. These systematic approaches can breathe subdivided into computational approaches and experimental approaches (Fig. 1), both of which are increasingly being used synergistically. Drug repurposing based on clinical data is encompassed within these two broad areas.

    Figure 1: Approaches used in drug repurposing. Figure 1

    Various computational approaches can breathe used individually or in combination to systematically analyse different types of large-scale data to obtain meaningful interpretations for repurposing hypotheses. Challenges for such analyses are discussed in Box 5. Experimental approaches can furthermore breathe used to identify repurposing opportunities. EHR, electronic health record.

    Computational approaches

    Computational approaches are largely data-driven; they involve systematic analysis of data of any kind (such as gene expression, chemical structure, genotype or proteomic data or electronic health records (EHRs)), which can then lead to the formulation of repurposing hypotheses11 (Fig. 1). The most commonly used computational approaches, together with drug repurposing examples, are discussed below.

    Signature matching. Signature matching is based on the comparison of the unique characteristics or 'signature' of a drug against that of another drug, disease or clinical phenotype12,13. The signature of a drug could breathe derived from three generic types of data: transcriptomic (RNA), proteomic or metabolomic data; chemical structures; or adverse event profiles, which they discuss in whirl below.

    Matching transcriptomic signatures can breathe used to beget drug–disease comparisons (estimating drug–disease similarity)14 and drug–drug comparisons (drug–drug similarity)15. In the first case, the transcriptomic signature of a particular drug is derived by comparing the gene expression profile of biological material, such as a cell or a tissue, before and after treatment with the drug; the resultant differential gene expression signature (the molecular signature of the drug) is then compared with a disease-associated expression profile that has been similarly obtained through differential expression analysis of disease versus robust conditions. The extent of negative correlation between the gene expression signature of the drug and that of the disease (that is, the genes upregulated in the disease are downregulated with the drug and vice versa) would then allow inference of whether the drug may own a potential consequence on the disease16,17 (see the case study of topiramate in Box 2). This computational approach relies on the signature reversion principle (SRP), where it is assumed that if a drug can invert the expression pattern of a given set of genes that are a hallmark for a particular disease phenotype (that is, the drug signature will breathe closer to that obtained for the robust state), then that drug might breathe able to revert the disease phenotype itself. Despite this principle being quite simplistic, it has been demonstrated for metabolic disorders18 and successfully exploited to identify novel drug repositioning opportunities in a wide range of therapeutic areas19,20,21,22,23,24. The SRP has furthermore been successfully employed to identify drugs that could breathe repositioned as chemo-sensitizers based on anticancer drug-resistance signatures25.

    Box 2: Drug–disease similarity approach to identify topiramate in IBD

    Dudley and colleagues16 compared the gene expression signature of inflammatory bowel disease (IBD) derived from publicly available data obtained from the National center for Biotechnology Information (NCBI) Gene Expression Omnibus with the gene expression profile of 164 drugs obtained from the Connectivity Map (cMap). Therapeutic predictions for drug–disease pairs were derived based on the extent of negative correlation between the gene expression signature of the drug and that of the disease. One of the strongest therapeutic predictions they obtained for IBD was the corticosteroid prednisolone, which is widely used to reduce inflammation associated with IBD. Another drug that showed a stronger correlation with both Crohn's disease and ulcerative colitis — two famous clinical manifestations of IBD — was topiramate, an antiepileptic drug with GABA agonistic activity.

    The authors validated the potential efficacy of topiramate in IBD using a trinitrobenzenesulfonic acid-induced rat model of IBD, in which it significantly reduced diarrhoea, visual manifestations of colitis on endoscopy and microscopic manifestations of disease on colonic biopsy. Functional enrichment analysis indicated that genes involved with gastrointestinal disease, inflammatory response and other immune-related functions were divergently expressed between the drug-affected and disease-affected conditions, further highlighting some of the potential mechanisms by which topiramate may act in IBD. However, a recent retrospective cohort study using administrative claims data from the MarketScan databases in the US failed to prove a advantageous consequence of topiramate in IBD110. Nevertheless, it is involving to note that GABA has been recently suggested to play a potential role in gastrointestinal inflammation111. Thus, an appropriately designed and powered randomized clinical tribulation would breathe required to definitively retort the question of whether topiramate can breathe used therapeutically in IBD.

    Drug–drug similarity approaches direct to identify shared mechanisms of action of otherwise dissimilar drugs (drugs that belong to different classes or that are structurally dissimilar). This principle is called guilt by association26 and can aid the identification of alternative targets of existing drugs and uncover potential off-target effects that can breathe investigated for clinical applications12. A shared transcriptomic signature between two drugs could therefore imply that they furthermore share a therapeutic application, regardless of the similarity or dissimilarity in their chemical structures27 (see the case study of fasudil in Box 3). This principle has proved efficacious even when comparing transcriptional signatures that are reflective of a secondary mode of action, which could breathe shared, for example, by a group of pharmacologically diverse mild correctors of a given disease phenotype28,29.

    Box 3: Drug–drug similarity approach to identify the potential utilize of fasudil in amyotrophic lateral sclerosis

    Iorio and colleagues27,112 used the 'guilt by association' principle to construct a drug network using publicly available transcriptomic profiles of drugs, which allowed them to identify drugs with a similar transcriptional signature and therefore a perceived similar mechanism of action. Using gene expression profiles of each drug across multiple treatments on different cell lines and/or at different dosages obtained from the Connectivity Map (cMap), they computed a representative transcriptional response for each drug. A drug network was then constructed in which two drugs were connected to each other if their optimal transcriptional responses were similar according to a similarity measure developed by the authors (called drug distance). This resulted in a drug network of 1,302 nodes (drugs) and 41,047 edges (indicating similarities between pairs of drugs) purely based on transcriptomic profiles of drugs within this network consisting of drugs with a similar transcriptional signature and therefore a perceived similar mechanism of action.

    Using this network, the authors correctly predicted the previously known mechanism of action of nine anticancer compounds, thereby validating this predictive model. Importantly, they furthermore predicted previously unknown mechanisms for drugs such as fasudil, a Rho-kinase (ROCK) inhibitor, based on its proximity to known autophagy enhancers such as 2-deoxy-d-glucose and tamoxifen, and validated their prediction using an in vitro fibroblast model112. Autophagy plays a key role in the pathogenesis of amyotrophic lateral sclerosis (ALS)113, a neurodegenerative disease with no cure. Preclinical studies in animal models of ALS showed that fasudil can augment motor neuron survival in transgenic mice expressing mutant superoxide dismutase 1 (SOD1), the causal gene for congenital forms of ALS114. The advantageous effects of fasudil in preclinical models of ALS were furthermore confirmed in other preclinical studies115,116. This has now led to an open-label, single-centre clinical tribulation in China to investigate the efficacy and safety of fasudil in ALS (NCT01935518).

    Both drug–disease and drug–drug similarity approaches involve matching of transcriptomic signatures and therefore reckon heavily on publicly accessible gene expression data. The Connectivity Map (cMap), which was established in 2006 by the Broad Institute, consists of gene expression profiles generated by dosing of more than 1,300 compounds in a number of cell lines30 (Connectivity Map; descry Related links). cMap information can breathe considered as a proxy phenotypic screen for a great number of compounds and has been successfully used to beget drug repurposing predictions for a number of disease conditions. The third instalment of the cMap data repository (cMap 3.0) is now available within the US National Institutes of Health (NIH) Library of Integrated Network-based Cellular Signatures (LINCS; descry Related links). It encompasses transcriptional signatures generated with tens of thousands of compounds upon treatment of hundreds of human cell lines. This stupendous resource can breathe used along with other famous public repositories of transcriptomic data, such as the Gene Expression Omnibus (see Related links) and Array Express (see Related links), which accommodate raw gene expression data from hundreds of disease conditions in humans and animal models. Manual curation or dedicated computational tools31 can then breathe used to interrogate these disease signatures in association with the cMap data to identify novel drug–disease connections and potential drug repositioning opportunities32,33.

    The second kind of signature matching used in drug repurposing is based on chemical structures and their relationship to biological activity34; comparing the chemical signature of one drug with that of another drug to descry whether there are chemical similarities could insinuate shared biological activity. The process involves selecting a set of chemical features for each drug and then constructing networks based on the shared chemical features. This is exemplified by the statistics-based cheminformatics approach undertaken by Keiser and colleagues12 to prognosticate fresh targets for 878 US Food and Drug Administration (FDA)-approved small-molecule drugs and 2,787 pharmaceutical compounds. Using a similarity ensemble approach (SEA) to evaluate the 2D structural similarity of each drug to each target's ligand set, they were able to identify 23 fresh drug–target associations.

    Chemical similarity approaches own their pitfalls: errors in chemical structures as well as physiological effects that exist beyond the structural relationship (for example, a metabolite of the original drug with a modified structure could breathe the lively molecule) could circumscribe the utilize of this approach in drug repurposing14.

    Finally, every drug has a relatively unique adverse consequence profile that could breathe used as a proxy for its phenotype. Matching the adverse consequence signature of drugs is based on the hypothesis that two drugs that occasions the identical adverse effects may breathe acting on a shared target or protein or on the identical pathway14. It is furthermore feasible that the adverse consequence phenotype of a particular drug may resemble that of a disease; this would insinuate shared pathways and physiology by both the drug and the disease. Peer Bork's group used the adverse consequence similarity approach to identify novel drug–target relationships for 746 approved drugs35. They used the Unified Medical Language System (UMLS) ontology for medical symptoms and extracted apposite adverse consequence profiles from drug package inserts, weighted them based on frequency and scored these drugs based on adverse consequence similarities. This approach not only confirmed previously known drug–drug pairs that shared the identical protein target but furthermore identified fresh shared targets for 754 drug pairs. A different approach was used by Yang and Agrawal to match adverse drug effects with disease36; they combined adverse consequence information derived from drug labels with drug–disease relationships obtained from the PharmGKB database and were able to prognosticate repurposing indications for 145 diseases.

    Although this is a rational approach to utilize for identifying repurposing opportunities, the rigor in mining adverse consequence information from drug package inserts and the requisite of well-defined adverse consequence profiles and causality assessments for a number of drugs14 could circumscribe its use. However, simulated intelligence technologies that can undertake text mining and natural language processing represent potential future opportunities to overcome these limitations.

    Computational molecular docking. Molecular docking is a structure-based computational strategy to prognosticate binding site complementarity between the ligand (for example, a drug) and the target (for example, a receptor)37. If there is prior learning of a receptor target involved in a disease, then multiple drugs could breathe interrogated against that particular target (conventional docking: one target and multiple ligands). Conversely, drug libraries could breathe explored against an array of target receptors (inverse docking: several targets and one ligand) to identify novel interactions that can breathe taken forward for repurposing. Using high-throughput computational docking, Dakshanamurthy and colleagues38 performed molecular happy computations on 3,671 FDA-approved drugs across 2,335 human protein crystal structures. They discovered that mebendazole, an anti-parasitic drug, has the structural potential to inhibit vascular endothelial growth factor receptor 2 (VEGFR2), a mediator of angiogenesis; this was furthermore confirmed experimentally.

    However, there are several issues with the utilize of molecular docking for drug repurposing. First, 3D structures for some protein targets of interest may not breathe available, particularly because drug targets are often membrane proteins, such as G protein-coupled receptors (GPCRs), although substantial progress has recently been made in GPCR crystallography39. Second, there is a requisite of well-curated macromolecular target databases that provide accurate structural information40, although this is getting better41. Finally, the utility of docking algorithms to prognosticate the affinity of binding has been questioned42 and, while it is improving, there can breathe differences between different software packages, and some limitations in predictability (for instance, mode of binding and entropic effects) soundless remain43.

    Genome-wide association studies. There has been a great augment in the number of genome-wide association studies (GWAS) conducted over the past 10 years following advances made in genotyping technology, the completion of the Human Genome Project and dwindling genotyping costs. GWAS direct to identify genetic variants associated with common diseases and thereby provide insights into the biology of diseases; the data obtained may furthermore serve identify novel targets, some of which could breathe shared between diseases treated by drugs and disease phenotypes studied by GWAS and thereby lead to repositioning of drugs44. Sanseau and colleagues44 refined the catalogue of published GWAS traits from the US National Human Genome Research Institute (NHGRI) and institute that genes that were associated with a disease trait were more likely to code for proteins that are 'druggable' or 'biopharmable' than the rest of the genome, with the GWAS gene set enriched by 2.7-fold in targets being pursued by the pharmaceutical industry. They furthermore institute 92 individual genes with a GWAS trait that was different from the original drug indication, suggesting that it is feasible to evaluate drugs that target the products of these 92 genes for a fresh disease indication (see the case study for denosumab in Box 4). Another recent study by Grover and colleagues45 used a bioinformatics approach to match gene targets identified for coronary artery disease with drug information obtained by integration of three different drug–target databases (DrugBank, Therapeutic Target Database and PharmGKB) to identify potential repositioning opportunities.

    Box 4: utilize of GWAS-identified targets for potential repurposing of denosumab in Crohn's disease

    Denosumab (Prolia, Amgen), which is marketed for the treatment of postmenopausal women at elevated risk of fracture with osteoporosis, is an antibody that targets tumour necrosis factor ligand superfamily member 11 (TNFSF11), furthermore known as RANKL. TNFSF11 has furthermore been shown to breathe activated in Crohn's disease, in which a substantial harmony of patients own osteopenia and osteoporosis117. Moreover, a TNFSF11 genetic variant (rs2062305) has furthermore been associated with Crohn's disease by genome-wide association studies (GWAS)118.

    This prompted Sanseau and colleagues44 to speculate about a potential role for denosumab in Crohn's disease. Using human B-lymphoblastoid cells and osteoblasts, they institute that the Crohn's disease-associated TNFSF11 variant was associated with the differential expression of TNFSF11 and was able to interpret population variation in TNFSF11 expression in both cell types representing sever cellular lineages apposite for both inflammatory and bone disease. This provided further support to postulate a causal link between TNFSF11 and Crohn's disease and the potential for repurposing denosumab in Crohn's disease. A recent preclinical study explored the efficacy of daily denosumab injection in a mouse model of colitis induced by dinitrobenzenesulfonic acid119. Denosumab was institute to lessen pro-inflammatory cytokines and modify the gut microbiota diversity in this animal model, further supporting its potential utilize in treating manifestations of inflammatory bowel disease. The identical investigators are currently conducting an open-label side I/II tribulation of denosumab in patients with lively Crohn's disease (NCT02321280). The study is due for completion in July 2019.

    However, there are challenges in the utilize of GWAS information for drug repositioning, and its utility at present is unclear. GWAS signals in gene-rich loci with tenacious linkage disequilibrium may beget identification of causal gene and/or gene variants difficult44. Another issue is the requisite of information on the direction of consequence of the gene variant; functional studies will requisite to breathe conducted to ascertain this before deciding whether an activator or a suppressor is required to control the disease44. GWAS data Do not provide particular pathophysiological information, and hence, rational utilize of GWAS data is advocated before predicting repurposing targets46. It should furthermore breathe noted that the current understanding of the human genome is not final and there may breathe many more fresh genes discovered47.

    Pathway or network mapping. Pathway-based or network-based approaches own been widely used to identify drugs or drug targets that may own potential in repurposing48. As discussed above, even though some of the potential targets institute by GWAS or other means may beget themselves directly amenable as drug targets, quite often, these genes may not breathe ideal druggable targets. In such circumstances, a pathway-based strategy may provide information on genes that are either upstream or downstream of the GWAS-associated target and could breathe exploited for repurposing opportunities49. Network analysis involves constructing drug or disease networks based on gene expression patterns, disease pathology, protein interactions or GWAS data in order to aid identification of repurposing candidates. Some of the signature matching studies discussed earlier furthermore beget utilize of the network analysis approach27,50. A recent study by Greene and colleagues51 combined genetic variant information arising from GWAS with tissue-specific functional interaction networks using a technique termed network-wide association study (NetWAS) to identify disease–gene associations much more accurately than GWAS alone. By applying this strategy to hypertension and by querying the resultant data against drug–target data from DrugBank, they observed that targets of antihypertensive drugs were enriched to a greater extent among the top genes from NetWAS than with GWAS. Pathway analysis of gene expression data sets from studies involving a wide range of respiratory viruses in human host infection models identified 67 common biological pathways that may breathe famous in respiratory viral infections48. Interrogation of these pathways against the DrugBank database identified several drugs with a potential consequence against host-viral targets. These included pranlukast, a leukotriene receptor 1 antagonist used in asthma, and amrinone, a phosphodiesterase inhibitor used in the treatment of congestive heart failure. It has been postulated that both of these drugs could breathe useful in treating viral infections owing to their potential aptitude to alter the immune response.

    Retrospective clinical analysis: utilize of electronic health records. The best example of retrospective clinical analysis leading to repurposing (or rescue if the drug had otherwise failed for its primary indication) of a candidate molecule is sildenafil1. Other examples for repurposing opportunities arising from retrospective clinical and/or pharmacological analyses embrace aspirin in colorectal cancer (the US Preventive Services job compel released draft recommendations in September 2015 regarding the utilize of aspirin to serve avert cardiovascular disease and colorectal cancer52), raloxifene in breast cancer (Evista; approved by the FDA to reduce the risk of hormone-receptor-positive breast cancer in postmenopausal women who own not been diagnosed but are at higher-than-average risk of disease) and propranolol in osteoporosis53. However, the above cited examples did not arise as a result of a systematic analysis of clinical data. A systematic approach for analysing clinical data is now increasingly suggested for identifying drug repurposing opportunities54.

    Retrospective clinical data can breathe obtained from various sources, including EHRs, post-marketing surveillance data and clinical tribulation data. EHRs accommodate an stupendous amount of data on patient outcomes, both structured and unstructured. The diagnostic and pathophysiological data, including the results of laboratory tests as well as drug prescribing data, are more structured; however, EHRs furthermore accommodate considerable amounts of unstructured information, such as clinical descriptions of patient symptoms and signs (which are famous in defining disease phenotype) and imaging data. This wealth of data present in EHRs could breathe used as a source for identifying signals for drug repurposing11; in addition, the stupendous amount of EHR data furthermore provides elevated statistical power55. Paik and colleagues55 extracted clinical signatures from over 13 years of EHRs from a tertiary hospital, including >9.4 million laboratory tests from half a million patients, in addition to diverse genomics signatures to identify over 17,000 known drug–disease associations; this approach led to the identification of terbutaline sulfate, an anti-asthmatic, as a promising candidate for the treatment of amyotrophic lateral sclerosis (ALS).

    The UK Clinical rehearse Research Datalink (CPRD), the Yellow Card scheme of the Medicines and Healthcare Products Regulatory Agency (MHRA), EudraVigilance (a European database of suspected adverse drug reaction reports managed by the European Medicines Agency (EMA)), the FDA Adverse Event Reporting System (FAERS) and the World Health Organization (WHO) global database for adverse drug reactions (VigiBase) utter accommodate valuable patient, disease and drug data that could serve as famous sources for drug repurposing analyses. However, considerable challenges soundless equivocate ahead in accessing and using EHR data, including ethical and legal obstacles that circumscribe access to the data and rigor in extracting the unstructured information present in these databases. pile more research capability into EHR databases could serve improve their utility for various downstream opportunities such as drug repurposing. Natural language processing and machine-learning techniques could furthermore prove valuable.

    Post-marketing surveillance data and clinical tribulation data are two other famous Big data sources, but access may breathe limited for commercial or confidentiality reasons. However, there is increasing realization that opening up access to such wealth of information can aid further drug development research. In October 2016, the EMA started providing direct public access to clinical tribulation data submitted by pharmaceutical companies and has published reports on six different drugs to date (European Medicines Agency Clinical Data; descry Related links). The data can breathe used for independent reanalysis by academics and researchers and may argue drug repurposing leads.

    Novel sources of data for drug repurposing. Immortalized human cancer cell lines (CCLs) own been used in high-throughput drug screens against hundreds of compounds (both approved and experimental) to test their consequence on cell viability56,57. In a number of studies, the pharmacological data sets resulting from these screens own been paired with comprehensive genomic characterization of the probed CCLs, thereby allowing identification of interactions between molecular features of the cell and drug response (pharmacogenomic interactions)58,59,60,61. Mining such publicly available data sets containing paired genomic and pharmacological data on great panels of CCLs has been suggested as a novel resource for identifying drug repositioning opportunities. CCLs are of course imperfect models: they might own acquired molecular alterations providing selective advantages for in vitro culture and are often biased towards certain molecular subtypes. However, despite these limitations, studies own shown how identifying pharmacogenomic interactions recapitulate therapeutic genomic markers already in clinical use, with a force of association that is comparable to that observed in the clinic58,59,60,61.

    More recently, CCL studies own furthermore been integrated with the genomic characterization of great cohorts of primary tumours to prioritize the identified pharmacogenomic interactions on the basis of the clinical prevalence of the involved genomic alterations60. Strikingly, many of the novel identified pharmacogenomic interactions were specific to cancers of a given tissue kind and involved drugs that are already in clinical utilize for other diseases or for cancers of other tissue types. The data arising from these types of study could breathe used to identify drug repurposing opportunities. Furthermore, this novel investigative avenue would tender an additional advantage: identification of the genomic alteration involved in a pharmacogenomic interaction with a repurposable drug would allow it to breathe prescribed to a very well-defined subpopulation of patients, thus advancing personalized cancer therapy.

    EHR-linked great DNA biobanks could breathe another frontier in accelerating drug repurposing research62. GlaxoSmithKline utilized China Kadoorie Biobank (CKB)63, a prospective cohort of half a million individuals, to examine the role of PLA2G7 gene variants in major vascular disease64 following the failure of two consecutive side III trials for darapladib (an inhibitor of the PLA2G7 gene product Lp-PLA2) in coronary heart disease and acute coronary syndrome65,66. PLA2G7 gene variants did not prove any association with major vascular disease, providing further support for findings from the side III trials. Although a biobank resource was used to authenticate the requisite of efficacy of a drug in this case, the identical approach could breathe used to authenticate gene targets for drug repurposing. Tapping into resources offered by great biobanks that are linked to EHRs, such as the UK Biobank, may breathe a valuable approach for assessing potential drug targets.

    Advances in sequencing technologies are enabling the collection of great quantities of comprehensive genomic data from many individuals that could breathe useful for drug repurposing. For example, the HiSeq X Ten system developed by Illumina (San Diego, California) is able to sequence more than 18,000 total human genomes per year (the volume of which will breathe 3.6 petabytes or 3,600 terabytes)67. Large-scale projects harnessing such technologies embrace the 100,000 genome project launched in the UK in 2014 (Ref.68), which has a focus on rare diseases and cancer, and the utter of Us research programme in the United States (formerly called the Precision Medicine Initiative69), which will genotype 1 million individuals. This is in addition to various initiatives by other countries (for example, China has announced its own precision medicine genome sequencing initiative, with an estimated cost of $9.2 billion70) and private consortia (for example, AstraZeneca's genome sequencing initiative in drug discovery (see Related links) in collaboration with Human Longevity in the US, the Wellcome trust Sanger Institute in the UK and The Institute for Molecular Medicine in Finland, which will involve 2 million individuals). Data from these projects could provide fresh insights into the genetic basis of disease and argue therapeutic targets for both fresh drug discovery and opportunities for drug repurposing, as with GWAS discussed above. This could breathe particularly valuable for rare diseases (Box 1) if causative genetic variations are identified in proteins for which potential candidates for drug repurposing are already available. For example, the phosphatidylinositol 3-kinase α-selective inhibitor, alpelisib (BYL719), which has been developed for the treatment of PIK3CA-altered tumours71, was recently shown to breathe efficacious in a mouse model of, and in 19 human subjects with, PIK3CA-related overgrowth syndromes (PROS) based on the fact that affected patients own somatic, mosaic gain-of-function mutations in the PIK3CA gene72.

    Nevertheless, it should breathe noted that the nature of the Big data from such projects and from the utilize of other high-throughput technologies poses considerable challenges for analysis and efficacious application, both in fresh drug discovery and drug repositioning (Box 5).

    Box 5: The challenges of Big data

    Advances in technology such as next-generation sequencing and continuously reducing costs spell that researchers can generate great quantities of experimental data; these embrace data generated by high-throughput DNA and RNA sequencing, mass spectrometry, metabolomics and transcriptomic data, phenotyping and many more. Added to this are great amounts of clinical data that are increasingly becoming available from electronic health records (EHRs), clinical trials and biobanks. Such data are often referred to as Big data — data sets that are so great or involved that traditional data processing methods are inadequate120.

    Big data are famous for improving their understanding of disease and developing strategies for disease prevention and treatment. However, they are facing an increasing gap between their aptitude to generate Big biomedical data and their aptitude to integrate, analyse and interpret the data67. This is further compounded by their aptitude to generate great amounts of data in a minimal amount of time. Another problem with Big data is that they are disparate and heterogeneous, which makes data integration extremely difficult120,121. Integrating multiple types of data has proved to augment the power of analysis122, and there are already some examples in drug repurposing where this strategy has been utilized at a limited scale123,124. However, much of the data generated are unstructured, such as imaging and structural data, and this adds another layer of complexity. There is an exigent requisite for technology solutions that can combine heterogeneous data sets and integrate, analyse and interpret them.

    Finally, another bottleneck lies in accessing various types of data120,121. Although the publicly available databases for transcriptomic data are well known and accommodate standardized data, such databases are rare for other types of data, such as clinical tribulation data and structural, in vitro or imaging data. For example, access to clinical tribulation data is limited at the moment, and even if access is obtained, this may involve mining of stupendous amounts of data (for example, the clinical tribulation data published by the European Medicines Agency for only two drugs, carfilzomib and lesinurad, constitutes ~260,000 pages of information in over 100 clinical reports). Therefore, it is famous to own publicly accessible repositories that hold data in a standardized format and own the necessary tools to mine such data.

    Finally, online self-reported patient data own been suggested as another fresh potential source for drug repurposing11,73. One example is self-reported data on the usage of lithium carbonate by patients with ALS, which were used to derive useful conclusions about the efficacy of usage73. Even though no consequence of lithium on disease progression was identified, the approach suggests that data reported by patients over the Internet may breathe useful for accelerating clinical discovery and evaluating the effectiveness of drugs already in use. utilize of patient-reported outcome data collected over the Internet offers advantages such as faster data collection, reduced cost and enhanced patient engagement; however, this approach furthermore carries considerable risks in terms of warp and, potentially, patient safety if it involves patient self-prescribing.

    Experimental approaches

    Binding assays to identify target interactions. Proteomic techniques such as affinity chromatography and mass spectrometry own been used as approaches to identify binding partners for an increasing number of drugs74. In an era of chemical biology for target validation, analyses of the targets and off-targets of drugs and drug repurposing own become natural bedfellows. For example, the Cellular ThermoStability Assay (CETSA) technique has been introduced as a passage of mapping target tryst in cells using biophysical principles that prognosticate thermal stabilization of target proteins by drug-like ligands that possess the confiscate cellular affinity75.

    Examples of early successes with this technique embrace the confirmation of cellular targets for the tyrosine kinase inhibitor (TKI) crizotinib76 and the detection of quinone reductase 2 (NQO2) as a cellular off-target of acetaminophen (paracetamol)77. A requisite to address the promiscuity of protein kinase inhibitors has long been recognized78, and the prediction that protein kinases will represent the major drug targets of the 21st century79 may soundless breathe fulfilled. This has increased efforts to develop better probe compounds for preclinical research that can inform clinical drug development and repurposing through an evidence-based pharmacological 'audit trail' in cells80. It is furthermore famous to note that the 'mistakes' made in various kinase drug discovery approaches own much to contribute, and early-stage unbiased affinity approaches are particularly useful for understanding the likely effects of compounds in cells, which embrace paradoxical kinase activation by inhibitors81 that underlie mechanistic off-target tumour initiation in patients82. For example, to understand the complexity of compound effects, Brehmer and colleagues incubated HeLa cell lysate extracts with a matrix containing covalently attached gefitinib; mass spectrometry of the resultant elutes identified more than 20 different protein kinases as putative gefitinib targets74. Broader efforts own furthermore been employed to evaluate kinase inhibitors by employing affinity matrices containing 'kinobeads', which capture proteins before analytical quantification83, often revealing involving novel off-targets for well-known drugs84,85. Similar approaches own now revealed many of the molecular on and off targets for famous clinical agents, such as the first-to-market (and relatively specific) BCR–ABL inhibitor imatinib86, which has been successfully repurposed to deal KIT-driven gastrointestinal stromal tumours87, the newer BCR–ABL inhibitors nilotinib and dasatinib, and the very promiscuous kinase inhibitor ponatinib.

    Chemical genetics can furthermore provide a better understanding of the relationship between binding and efficacy in the cellular context88. In turn, these findings can breathe rapidly translated into fresh clinical areas or to address drug-resistance outcomes of prolonged exposure that are near-inevitable phenotypic responses to kinase inhibitor therapy in cancer89,90. Many of these studies originate from industry-driven high-throughput direct binding or catalytic assays, in which small-molecule–kinase binding is analysed in a kinome-wide vogue using a variety of in vitro and increasingly organism-based assays to generate heat maps of biologically famous interactions91,92. In one such study, Karaman and colleagues92 used an in vitro competition binding assay to evaluate 38 kinase inhibitors against a panel of 317 sever human protein kinases; their analysis identified a total of 3,175 binding interactions. Interestingly, some kinase inhibitors such as sorafenib and dasatinib showed higher affinity to secondary kinase targets than their known primary target, potentially informing (or invalidating) their utilize in patient populations. In the kinase sphere in particular, non-kinase targets of small molecules originally designed to inhibit protein kinases are increasingly recognized93 and are leading to repurposing opportunities in cancer19, as Zika virus modulators94 and as potential agents to deal antibiotic-resistant microorganisms95.

    Phenotypic screening. Phenotypic screening can identify compounds that prove disease-relevant effects in model systems without prior learning of the target(s) affected96. In the context of drug repurposing, if the compounds screened are approved or investigational drugs, this may argue repurposing opportunities that can readily breathe pursued. Typically, in vitro phenotypic screens utilize a wide range of cell-based assays in a 96-well format. For example, Iljin and colleagues97 conducted high-throughput cell-based screening of a library of 4,910 drug-like small-molecule compounds in four prostate cancer and two non-malignant prostate epithelial cell lines with proliferation as the primary conclude point. They identified disulfiram, a drug used for alcohol abuse, to breathe a selective antineoplastic agent, which was then validated using genome-wide gene expression studies. Whole-organism phenotypic assays are furthermore utilized in drug repurposing; Cousin and colleagues98 used a zebrafish model to evaluate 39 FDA-approved medications for utilize in tobacco dependence and institute that compounds such as apomorphine and topiramate modified nicotine-induced and ethanol-induced behaviour in this model.
