Protein structure-based drug design has been contributing to the drug discovery process since the early 1990s. Structural knowledge on the exact interactions of drugs with their target proteins has been applied mainly to predict potency changes of chemically modified lead compounds.. With the 3D-structural information available today, additional aspects of the drug discovery process become predictable. Target-based virtual screening is being applied to identify new unexpected lead structures. Selectivity of compounds between homologous or orthologous proteins can be predicted, offering new possibilities to design selective compounds or predict the suitability of animal models for pharmacodynamic studies. Also the number of x-ray structures of proteins relevant for ADMET properties of drug molecules has remarkably increased during the last few years. This development offers the possibility to modulate or rationally design out unwanted ADMET properties. This covers aspects such as plasma protein ...

Structure-based drug design (SBDD) has become a powerful tool utilized by medicinal chemists to rationally guide the drug discovery process. Herein, we describe the use of SPROUT, a de novo-based program, to identify an indazole-based pharmacophore for the inhibition of fibroblast growth factor receptor (FGFR) kinases, which are validated targets for cancer therapy. Hit identification using SPROUT yielded 6-phenylindole as a small fragment predicted to bind to FGFR1. With the aid of docking models, several modifications to the indole were made to optimize the fragment to an indazole-containing pharmacophore, leading to a library of compounds containing 23 derivatives ...
A method of rational drug design includes simulating polypeptides in a way that predicts the most probable secondary and/or tertiary structures of a polypeptide, e.g., an oligopeptide, without any presumptions as to the conformation of the underlying primary or secondary structure. The method involves computer simulation of the polypeptide, and more particularly simulating a real-size primary structure in an aqueous environment, shrinking the size of the polypeptide isobarically and isothermally, and expanding the simulated polypeptide to its real size in selected time periods. A useful set of tools, termed Balaji plots, energy conformational maps, and probability maps, assist in identifying those portions of the predicted peptide structure that are most flexible or most rigid. The rational design of novel compounds, useful as drugs, e.g., bioactive peptidomimetic compounds, and constrained analogs thereof, is thus made possible using the simulation methods and tools of the described invention.

Professional bodies and Institutes CPD schemes are either structured as Input or Output based. Input based schemes list a precise number of CPD hours that individuals must achieve within a given time period. These schemes can also use different currencies such as points, merits, units or credits, where an individual must accumulate the number required. These currencies are usually based on time i.e. 1 CPD point = 1 hour of learning. Output based schemes are learner centred. They require individuals to set learning goals that align to professional competencies, or personal development objectives. These schemes also list different ways to achieve the learning goals e.g. training courses, seminars or e:learning, which enables an individual to complete their CPD through their preferred mode of learning. The majority of Input and Output based schemes actively encourage individuals to seek appropriate CPD activities independently. As a formal provider of CPD certified activities, SMI Group ...

The antiviral therapeutic area continues to rapidly generate meaningful new chemical entities; for example, for HIV alone more than 25 drugs have been approved, and in the next few years many individual drugs and single tablet regimens will be approved for the treatment of hepatitis C virus infection. The increasing success in the antiviral area could be due to targeting drugs at non-self genomes and to the patient population that is tolerant of manageable side effects and adaptable to inconvenient dosing.Aimed at medicinal chemists and emerging drug discovery scientists, the book is organized according to the various strategies deployed for the discovery and optimization of initial lead compounds. This book focuses on capturing tactical aspects of problem solving in antiviral drug design, an approach that holds special appeal for those engaged in antiviral drug development, but also appeals to the broader medicinal chemistry community based on its focus on tactical aspects of drug design.

A primary objective of our research is to design new antibacterial agents based on novel mechanisms of action. Currently, all clinically used antibiotics act by one of a limited number of mechanisms (e.g. inhibition of protein synthesis, DNA synthesis, cell-wall synthesis, and RNA transcription). We utilize available data from experimental genetic approaches to identify candidate bacterial targets. In cases where the structure and enzymology of the bacterial enzyme is known, we rationally design substrate mimics or transition-state inhibitors. However, for many potential targets there is inadequate structural information available to permit such a structure-based drug design approach. In these cases we develop high-throughput-screening (HTS) assays that allow us to identify a lead candidate molecule. Once a small molecule inhibitor is identified against the targeted enzyme we then apply medicinal chemistry efforts to methodically optimize the inhibitor scaffold. Structure- and/or ligand-based ...

In this Letter, we provide the structure-activity relationships, optimization of design, testing criteria, and human half-life data for a series of selective COX-2 inhibitors. During the course of our structure-based drug design efforts, we discovered two distinct binding modes within the COX-2 active site for differently substituted members of this class. The challenge of a undesirably long human half-life for the first clinical candidate 1t(1/2)=360h was addressed by multiple strategies, leading to the discovery of 29b-(S) (SC-75416) with t(1/2)=34h.

Virtual screening of chemical databases to targets of known three-dimensional structure is developing into an increasingly reliable method for finding new lead candidates in drug development. Both better scoring functions and novel docking strategies contribute to this trend, although no completely satisfying approach has been established yet. This is not surprising since the approximations which are needed to achieve a reasonable screening rates impose significant restrictions on the virtual representation of the physical system. Relaxation of these restrictions, such as permitting ligand or receptor flexibility, potentially increase the reliability of the scoring process, but come at a high computational cost. While ligand flexibility is now routinely considered in many atomistic in-silico screening methods, accounting for receptor flexibility still poses significant challenges. Using the thymidine kinase inhibitors as a prototypical example we document the shortcoming of rigid receptor screens in a

In this seminar, we review the importance of chromatographic selectivity from a theoretical and practical perspective and how this relates to analyte resolution for method development. With an understanding of selectivity and using a variety of chromatographic data, we discuss phase design principles and how it is possible to introduce functionality that enhances selectivity, whilst maximising other desirable phase attributes such as phase stability, reproducibility and mechanisms of interaction. The resulting novel phases are explored for their improved chromatographic performance, selectivity and value in method development for a range of analytes and separations. Finally, method development approaches are discussed and pragmatic, simple method development platforms are illustrated based upon rational phase and eluent choice ...
Hepatic intrinsic clearance (CLint) is an important parameter for a drug candidate as it influences oral bioavailability as well as systemic exposure. Thus, it is common to determine this property early in drug discovery so that it can act as a compound selection criterion as well as aid medicinal chemists in drug design. The translation of drug leads into clinical candidates could be improved by the further development of in silico tools for reliable prediction of human clearance. The major enzymatic system responsible for metabolism of xenobiotics is the cytochrome P450 (P450) family (Nebert and Russell, 2002). P450s are responsible for more than 75% of drug metabolism, and the major isoform among these enzymes is CYP3A4, which is responsible for the metabolism of ∼50% of known xenobiotics in humans. Other important isoforms include CYP2C9, CYP2D6 and CYP1A2 (Guengerich, 1999, 2008). A joint team comprising of members from the International Consortium for Innovation and Quality in ...
A HIV-1 tier program continues to be developed to categorize the many subtype infections predicated on their level of sensitivity to vaccine-induced neutralizing antibodies (NAbs): tier 1 with finest level of sensitivity, tier 2 becoming delicate moderately, and tier 3 becoming the least delicate to NAbs (Mascola et al. short-duration (37C41 several BIBW2992 weeks) research. In long-duration (76C80 several weeks) research, the industrial vaccine afforded a mixed safety price of at least 46% contrary to the tier-2 and tier-3 infections. Notably, safety rates observed listed below are far better than recently reported HIV-1 vaccine trials (Sanou et al., The Open AIDS 2012; 6:246-60). Prototype vaccine protection against two tier-3 and one tier-2 viruses was more effective than commercial vaccine. Such protection did not correlate with the presence of vaccine-induced NAbs to challenge viruses. This is the first large-scale (228 laboratory cats) study characterizing short- and long-duration ...

The reason for the low number of successful new CNS drugs is the subject of debate, although it is undoubtedly related to their higher attrition rate during development, particularly from issues related to failures of on-target biological hypotheses. To address this problem, there has been a recent emphasis on research to tackle these issues at an earlier stage in the drug discovery pathway. In particular, there has been increased interest in target discovery both for the identification of novel targets and reducing the subsequent failure from incorrect biological hypotheses through early validation.. Target discovery, which involves the identification and early validation of disease-modifying targets, is an essential first step in the drug discovery process. Furthermore, although the knowledge of the target for a small molecule drug is not required by the FDA for drug development, it is crucial information if the drug discovery process is to be made more efficient and effective. Identifying the ...

The use of companion diagnostics in oncology is making the promise of patient stratification and the delivery of precision medicine more of a reality. In 2011 alone, the FDA approved 3 oncology agents indicated for biomarker-identified patient subpopulations: brentuximab vedotin (Adcetris; Seattle Genetics) for CD30-expressing Hodgkin lymphoma, crizotinib (Xalkori; Pfizer) for anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer, and vemurafenib (Zelboraf; Genentech) for metastatic melanoma with the BRAF (serine/threonine-protein kinase B-raf) V600E mutation (10).. Clinical trials for molecularly targeted therapies are more likely to prove effective when a strong biological hypothesis is evaluated in patients selected on the basis of the presence of a specific ...

Saturated azaheterocycles are popular in modern drug discovery programs. More than 50 FDA-approved drugs containing a fragment of pyrrolidine and piperidine have appeared on the market. Pyrrolidine/piperidine-based azasugars and their analogues are potent glycosidase inhibitors. These unique molecules promise a new generation of iminosugar-based medicines for a wide range of diseases. For example, a bioactive azasugar includes the anti-diabetic drug Glyset. In this context, herein we have designed and synthesized a library of sugar-like derivatives for drug design.. ...
Clumps of proteins that accumulate in brain cells are a hallmark of neurological diseases such as dementia, Parkinsons disease and Alzheimers disease. Over the past several years, there has been much controversy over the structure of one of those proteins, known as alpha synuclein.. MIT computational scientists have now modeled the structure of that protein, most commonly associated with Parkinsons, and found that it can take on either of two proposed states - floppy or rigid. The findings suggest that forcing the protein to switch to the rigid structure, which does not aggregate, could offer a new way to treat Parkinsons, says Collin Stultz, an associate professor of electrical engineering and computer science at MIT.. If alpha synuclein can really adopt this ordered structure that does not aggregate, you could imagine a drug-design strategy that stabilizes these ordered structures to prevent them from aggregating, says Stultz, who is the senior author of a paper describing the findings ...

Both docking cavities identified by the floodfill algorithm are in close vicinity to and in close contact with the earlier suggested NP epitope sequences studied in a previous study [21] (see Figure 1). Site 2 occupies an arginine-rich region of the RNA-binding groove and forms extensive contacts with another NP-conserved epitope sequence R174-K184, which makes the site very attractive for targeting NP. Meanwhile, Site 1 has only minor contact with another epitope sequence, I265-S274. Surprisingly, both Site 1 and Site 2 are distant from the proposed binding site of the recent NP inhibitor nucleozin, which is marked by the residue Y289 [17] on Figure 1.. The demonstrated level of animal protection in treatments with F66 reached 40%, which is comparable to the protection provided by treatment with rimantadine in a similar experiment (60%). In the emergency prophylaxis study, the compound application increased the lifetime of the mice by 2.7 days. The results are inferior to the protection level ...

One of the initial steps of modern drug discovery is the identification of small organic molecules able to inhibit a target macromolecule of therapeutic interest. discovery are urgently required if we are to tackle the multiple global health challenges of emerging and neglected infectious diseases for which there is relatively little basic science investment. Recently, Simmons and and [17]. This pathway is present in bacteria, fungi, plants and apicomplexan parasites, but not in mammals, and hence represents an ideal target for the development of antibacterial agents, as these agents would be expected to have a spectrum of antibacterial activity restricted to those human pathogens expressing DHQase such as and DHQase was used as a starting point to identify novel inhibitors [18]. While approximately 100 molecules with more than 50 per cent inhibition of DHQase enzyme activity at a concentration of 20 g ml?1 were identified in the primary screening, only one confirmed inhibitor against DHQase was ...

In todays study, a -panel of SL analogs continues to be evaluated for antiviral activity against HCMV. We demonstrate that TH-EGO and EDOT-EGO inhibit HCMV replication in vitro considerably, impairing past due protein expression. Furthermore, we show which the SL-dependent induction of apoptosis in HCMV-infected cells is normally a contributing system to SL antiviral properties. General, our outcomes indicate that SLs could be a appealing alternative to nucleoside analogs for the treatment of HCMV infections. subfamily, is one of the most significant opportunistic human pathogens. Although HCMV rarely causes symptomatic clinical manifestations in immunocompetent individuals, it induces severe morbidity and mortality in the immunocompromised population, following either primary infection or reactivation, leading to gastro-intestinal diseases, ...
In contrast to traditional methods of drug discovery (known as forward pharmacology), which rely on trial-and-error testing of chemical substances on cultured cells or animals, and matching the apparent effects to treatments, rational drug design (also called reverse pharmacology) begins with a hypothesis that modulation of a specific biological target may have therapeutic value. In order for a biomolecule to be selected as a drug target, two essential pieces of information are required. The first is evidence that modulation of the target will be disease modifying. This knowledge may come from, for example, disease linkage studies that show an association between mutations in the biological target and certain disease states.[16] The second is that the target is druggable. This means that it is capable of binding to a small molecule and that its activity can be modulated by the small molecule.[17] Once a suitable target has been identified, the target is normally cloned and produced and ...

Recently, metabolite characterization has shifted from the development stage of the drug discovery process and has become an integral component of early discovery-stage research. Concomitant with this shift has been a change in the type of information sought from metabolic studies. Although detailed qualitative and quantitative analysis of the metabolic pathway of a lead candidate continues to be an essential element of the drug development process, biotransformation information gleaned at the discovery stage can be used to guide synthetic chemistry efforts to either block or enhance metabolism with a view to optimizing the pharmacokinetic and safety profiles of newly synthesized compounds. Additionally, data on the metabolic fate of a large number of compounds may facilitate the development of structure-activity relationships for metabolism.. The availability of tandem mass spectrometers (McLafferty, 1980; Busch et al., 1988) has given the drug metabolism scientist a very powerful tool for ...

It was later discovered that the fatigued soldier suffered from good ol fashioned flu and was overcome by pneumonia - complicated by the stress and workload that come with being in the military. The U.S government prevented patients from taking action against negligent pharmaceutical companies by offering indemnity to the manufacturers. Todays swine flu threat is being promoted with the same fuzzy generalizations that spurred the demand for vaccines in 1976. The virus is still around and ready to explode, warned William Schaffner, an influenza expert (or pharmaceutical lapdog depending on how you look at it) at the Vanderbilt University School of Medicine. Were potentially looking at a very big mess, he insists. Yet, he provides no laboratory evidence whatsoever to back up his alarmist claims. In fact, as highlighted on the nationally syndicated Robert Scott Bell radio show (Google it), the World Health Organization (WHO) has issued a directive to stop testing for the ...
Although anti-retroviral therapy (ART) is impressive in suppressing HIV replication, it fails to eradicate the virus from HIV-infected individuals. reactivated following the interruption of anti-retroviral therapy (ART). Despite an early initiation of ART, viral reservoirs are established and persist as exhibited in the case of the Mississippi baby and from recent studies of the SIV model of AIDS. Therefore, new strategies are needed for the eradication of the latent HIV reservoirs. We found that ingenol-3-angelate (PEP005), a member of the new class of anti-cancer ingenol compounds, effectively reactivated HIV from latency in primary CD4+ T cells from HIV infected individuals receiving ART. Importantly, a combination of PEP005 and JQ1, a p-TEFb agonist, reactivated HIV from at level on average 7 latency.5-fold higher in comparison to PEP005 alone. The strength of synergistic ramifications of PEP005 and JQ1 offer novel possibilities for evolving HIV eradication strategies in the foreseeable ...
