applied mixed solvent molecular dynamics (MixMD) to predict three possible binding sites, which we confirmed using NMR-based solvent mapping. Using this knowledge, we then used NMR spectroscopy to carry out a fragment-based drug discovery (FBDD) screen, ultimately identifying two fragments that bind to one of these sites. A medicinal chemistry effort improved the affinity of one fragment by ~50-fold (16 µM)

suggest that P2Y1 and P2Y12 inhibition provide equivalent antithrombotic efficacy, while targeting P2Y1 has the potential for reduced bleeding liability. In this account, the discovery of a 2-(phenoxypyridine)-3-phenylurea chemotype that inhibited ADP-mediated platelet aggregation in human blood samples is described. Optimization of this series led to the identification of compound 16, 1-(2-(2-tert
activity, and increased the population of apoptotic cells. Relationships between structure and biological activity were determined by the QSAR (quantitative structure activity relationships) method. Analysis of quantitative structure activity relationships allowed us to generate OPLS (Orthogonal Projections to Latent Structure) models with verified predictive ability that point out key molecular descriptors
and pyrrolo[2,3-b]pyridines with a 4-benzylamine substitution have been evaluated as inhibitors of the epidermal growth factor receptor (EGFR). Substituent effects on the determined proteinkinase affinity have been discussed based on varied benzylamine residues at the differently substituted molecular scaffolds. Docking studies were carried out in order to explore the potential binding modes of the
具有4-苄基胺取代的新型苯并芳基呋喃和吡咯并[2,3- b ]吡啶已被评估为表皮生长因子受体(EGFR)的抑制剂。基于在不同取代的分子支架上的不同苄胺残基,已经讨论了对确定的蛋白激酶亲和力的取代基作用。为了研究新型抑制剂的潜在结合方式,进行了对接研究。观察到的活性数据促进了对胰岛素样生长因子受体(IGF-1R)抑制作用的测量,已知它在通过EGFR抑制剂抵抗癌症的发展中起着重要作用IGF-1R受体异二聚化。我们确定了两种激酶的新型双重抑制剂,并报告了它们的第一个癌细胞生长抑制数据。

higher cytotoxic activity againstA549 non-small cell lung adenocarcinoma and HCT-116 colon carcinoma cells and was less toxic to HEK-293 human embryonic kidney cells and HaCaT immortalized human keratinocytes. Treatment of A549 and HCT-116cells with compound 21 resulted in the G0/G1-cell cycle arrest with a concomitant increase in p53 and p21 protein levels. Moreover, compound 21 led to ATP depletion
