由于多重耐药菌株的传播,革兰氏阴性菌引起的感染越来越危险,强调迫切需要具有替代作用模式的新抗生素。我们之前使用抗叶酸靶向筛选确定了一类新型抗菌剂硫代乙酰胺-三唑,并确定了它们的作用方式,这取决于半胱氨酸合酶 A 的激活。在此,我们报告了对抗 E 的详细检查。硫代乙酰胺-三唑的大肠杆菌构效关系。合成了初始命中化合物的类似物,以研究芳基、硫代乙酰胺和三唑部分的贡献。观察到明确的结构-活性关系产生具有优异抑制值的化合物。对芳环的取代通常是最好的耐受性,包括引入噻唑和吡啶杂芳基系统。对中央硫代乙酰胺接头部分的替换更为细微;将甲基支链引入硫代乙酰胺接头显着降低了抗菌活性,但异构丙酰胺和 N-苯甲酰胺系统保留了活性。分子中三唑部分的变化显着降低了抗菌活性,进一步表明 1,2,3-三唑对效力至关重要。从这些研究中,我们确定了具有理想的体外 ADME 特性和体内药代动力学特性的新先导化合物。将甲基支链引入
The present invention relates to pyridyl derivatives capable of inhibiting phosphatidylinositol-3-kinase (PI3k), mammalian target of rapamycin (mTOR) and/or hypoxia inducible factor 1α (HIF-1α) mediated signaling. Also disclosed are processes for preparation of the pyridyl derivatives, and their use in the manufacture of pharmaceutical compositions for the treatment of clinical conditions caused by deregulation of signaling pathways selected from one or more of PI3K, mTOR and HIF-1α pathways. The pyridyl derivatives are also useful for the treatment of conditions or disorders mediated by TNF-α.

A series of novel cyanopyridyl based molecules (1-14) were designed, synthesized and probed for inhibition of mammalian target of rapamycin (mTOR) activity. Compound 14 was found to be a potent inhibitor of mTOR activity as assessed by enzyme-linked immunoassays and Western blot analysis. Most importantly, systemic application (intraperitoneal; ip) of compound 14 significantly suppressed macroscopic and histological abnormalities associated with chemically-induced murine colitis.
