Modern Applied Statistics With S

Flavonoids are nearly ubiquitous in plants and are recognized as the pigments responsible for the colors of leaves, especially in autumn. They are rich in seeds, citrus fruits, olive oil, tea, and red wine. They are low molecular weight compounds composed of a three-ring structure with various substitutions. This basic structure is shared by tocopherols (vitamin E). Flavonoids can be subdivided according to the presence of an oxy group at position 4, a double bond between carbon atoms 2 and 3, or a hydroxyl group in position 3 of the C (middle) ring. These characteristics appear to also be required for best activity, especially antioxidant and antiproliferative, in the systems studied. The particular hydroxylation pattern of the B ring of the flavonoles increases their activities, especially in inhibition of mast cell secretion. Certain plants and spices containing flavonoids have been used for thousands of years in traditional Eastern medicine. In spite of the voluminous literature available, however, Western medicine has not yet used flavonoids therapeutically, even though their safety record is exceptional. Suggestions are made where such possibilities may be worth pursuing.

The Effects of Plant Flavonoids on Mammalian Cells:Implications for Inflammation, Heart Disease, and Cancer

The development and clinical application of inhibitors that target the epidermal growth factor receptor (EGFR) provide important insights for new lung cancer therapies, as well as for the broader field of targeted cancer therapies. We review the results of genetic, biochemical and clinical studies focused on somatic mutations of EGFR that are associated with the phenomenon of oncogene addiction, describing 'oncogenic shock' as a mechanistic explanation for the apoptosis that follows the acute treatment of susceptible cells with kinase inhibitors. Understanding the genetic heterogeneity of epithelial tumours and devising strategies to circumvent their rapid acquisition of resistance to targeted kinase inhibitors are essential to the successful use of targeted therapies in common epithelial cancers.

The role of fluorine in drug design and development is expanding rapidly as we learn more about the unique properties associated with this unusual element and how to deploy it with greater sophistication. The judicious introduction of fluorine into a molecule can productively influence conformation, pKa, intrinsic potency, membrane permeability, metabolic pathways, and pharmacokinetic properties. In addition, 18F has been established as a useful positron emitting isotope for use with in vivo imaging technology that potentially has extensive application in drug discovery and development, often limited only by convenient synthetic accessibility to labeled compounds. The wide ranging applications of fluorine in drug design are providing a strong stimulus for the development of new synthetic methodologies that allow more facile access to a wide range of fluorinated compounds. In this review, we provide an update on the effects of the strategic incorporation of fluorine in drug molecules and applications in po...

Applications of Fluorine in Medicinal Chemistry

The parametrization and validation of the OPLS3 force field for small molecules and proteins are reported. Enhancements with respect to the previous version (OPLS2.1) include the addition of off-atom charge sites to represent halogen bonding and aryl nitrogen lone pairs as well as a complete refit of peptide dihedral parameters to better model the native structure of proteins. To adequately cover medicinal chemical space, OPLS3 employs over an order of magnitude more reference data and associated parameter types relative to other commonly used small molecule force fields (e.g., MMFF and OPLS_2005). As a consequence, OPLS3 achieves a high level of accuracy across performance benchmarks that assess small molecule conformational propensities and solvation. The newly fitted peptide dihedrals lead to significant improvements in the representation of secondary structure elements in simulated peptides and native structure stability over a number of proteins. Together, the improvements made to both the small mole...

The present invention relates to imidazo[1,2-a]pyrimidine derivatives, that are useful for treating cellular proliferative diseases, for treating disorders associated with MET activity, and for inhibiting the receptor tyrosine kinase MET. The invention also related to compositions which comprise these compounds, and methods of using them to treat cancer in mammals.

Tyrosine kinase inhibitors

Drugs with prolonged on-target residence times often show superior efficacy, yet general strategies for optimizing drug-target residence time are lacking. Here we made progress toward this elusive goal by targeting a noncatalytic cysteine in Bruton's tyrosine kinase (BTK) with reversible covalent inhibitors. Using an inverted orientation of the cysteine-reactive cyanoacrylamide electrophile, we identified potent and selective BTK inhibitors that demonstrated biochemical residence times spanning from minutes to 7 d. An inverted cyanoacrylamide with prolonged residence time in vivo remained bound to BTK for more than 18 h after clearance from the circulation. The inverted cyanoacrylamide strategy was further used to discover fibroblast growth factor receptor (FGFR) kinase inhibitors with residence times of several days, demonstrating the generalizability of the approach. Targeting of noncatalytic cysteines with inverted cyanoacrylamides may serve as a broadly applicable platform that facilitates 'residence time by design', the ability to modulate and improve the duration of target engagement in vivo.

Prolonged and tunable residence time using reversible covalent kinase inhibitors

To fully exploit the potential of kinases as drug targets, novel strategies for the efficient discovery of inhibitors are required. In contrast to the traditional, linear process of inhibitor discovery, high-throughput kinase profiling enables a parallel approach by interrogating compounds against hundreds of targets in a single screen. Compound potency and selectivity are determined simultaneously, providing a choice of targets to pursue that is guided by the quality of lead compounds available, rather than by target biology alone.

p38R is a member of the well characterized mitogen activatedprotein (MAP) kinase familyof serine/threonineprotein kinases. p38R is widely expressed in endothelial, immune, and inflammatory cells and plays a central role in the regulation of proinflammatory cytokine production including TNF-R, IL-1β, and IL-6. Selective blockade of any one of these cytokineswith biologic agents has proven efficacious for inflammatory diseases including rheumatoid arthritis (RA), psoriasis, and inflammatory bowel disease. The p38 subfamily of MAP kinases includes four isoforms (p38R, p38β, p38γ, and p38δ) that are encoded by separate genes. Analysis of differential tissue expression and activation of these isoforms in synovial tissue extracted fromRApatients has suggested that the p38R isoform is overactivated within inflamed tissue andmay be a preferred target for intervention in the disease. This expectation has prompted a huge investment by thepharmaceutical industry in thedevelopment of p38R inhibitors as potential oral disease modifying antirheumatic drugs (DMARDs). This Perspective will summarize key learnings from over 15 years of industrial experience with p38R as a drug target, with a focus on the rational design of highly selective small molecule inhibitors, followed by a discussion of data for examples 1-11 that have entered into or are recruiting for phase 2 clinical studies (summarized in Table 1). To date, these results have been disappointing.We conclude that p38R inhibition alone is unlikely to be a successful strategy toward treating chronic inflammatory disorders. Others have also concluded that “the era of optimism surrounding the use of p38 MAPK inhibition for the treatment of RA is over”.

p38 mitogen activated protein (MAP) kinase remains the most compelling therapeutic target for oral drug intervention for a wide range of autoimmune disorders based on the central role this enzyme plays in inflammatory cell signaling Efforts to discover inhibitors of p38 suitable for clinical investigation have continued to escalate in part due to the incredible diversity of unique chemotypes reported to inhibit the enzyme Since 1993, at least seventeen p38 inhibitors have been reported to have entered into clinical trials Next generation inhibitors have been disclosed with improved potency for p38 and enhanced selectivity versus other protein kinases Over the last three years, there have been multiple reports of cytokine suppression in humans following oral administration of p38 inhibitors These results, in addition to proof of concept studies in rheumatoid patients, have established p38 inhibition as an avenue for the future management of pro-inflammatory cytokine based diseases This review describes the discovery at Roche of novel p38 inhibitors which have advanced into clinical trials The pharmacology of the Roche compounds is then compared with eight chemically distinct p38 inhibitors known to have entered clinical development
