Development of antitubercular compounds based on a 4-quinolylhydrazone scaffold. Further structure–activity relationship studies
摘要:
A series of 4-quinolylhydrazones was synthesized and tested in vitro against Mycobacterium tuberculosis. At a concentration of 6.25 mu g/mL, most of the newly synthesized compounds displayed 100% inhibitory activity against M. tuberculosis in cellular assays. Further screening allowed the identification of very potent antitubercular agents. Compound 4c was also tested in a time-course experiment and against mtb clinical isolates, displaying interesting results. (C) 2009 Elsevier Ltd. All rights reserved.

structural optimization on type II inhibitors by truncation of the imidazonaphthyridinone core and incorporation of an N-phenyl cyclopropane-1,1-dicarboxamide pharmacophore led to the discovery of novel imidazopyridine-based c-Met kinase inhibitors, displaying nanomolar enzyme inhibitory activity and improved Met kinase selectivity. More significantly, the new chemotype c-Met kinase inhibitors effectively
从我们先前鉴定的带有1 H-咪唑并[4,5- h ] [1,6]萘啶-2(3 H)-一个支架的新型c-Met激酶抑制剂开始,进行了全面的结构探索以提供最佳结合由酶抑制机制指导的进一步开发的母题。第一轮SAR研究选择了两个具有1,8-和3,5-二取代模式的咪唑并萘啶酮框架,分别作为I类和II类c-Met激酶抑制剂。通过截短咪唑并萘啶酮核心并掺入N对II型抑制剂进行进一步的结构优化-苯基环丙烷-1,1-二甲酰胺酰胺药效基团导致发现了新型的基于咪唑并吡啶的c-Met激酶抑制剂,显示出纳摩尔酶抑制活性并提高了Met激酶的选择性。更重要的是,新型化学型c-Met激酶抑制剂在亚微摩尔浓度下可有效抑制Met磷酸化及其下游信号以及Met依赖性EBC-1人肺癌细胞的增殖。
