细菌对抗生素的抗性目前是最紧迫的医疗保健挑战之一,因此有必要发现具有独特化学支架的新型抗菌剂。然而,确定新的抗菌化合物的药理作用的结构要求和药代动力学性质之间的最佳平衡是药物开发中的重大挑战。在化合物的核心结构中掺入亲脂性部分可以增强生物活性,但对类似药物的性质具有有害作用。在本文中,通过将环胺引入亲脂性侧链,降低了先前被确定为新型抗菌剂的炔基苯基噻唑的亲脂性。在这方面,与第一代先导化合物1b相比,用甲基哌啶(化合物14-16)和硫代吗啉(化合物19)取代基取代可显着提高新化合物的水溶解度150倍以上。因此,化合物15的药代动力学曲线得到显着增强,同时半衰期和化合物血浆浓度保持高于其对耐甲氧西林金黄色葡萄球菌(MRSA)的最小抑菌浓度(MIC)以上的时间均得到显着改善。另外,发现化合物14-16和19对MRSA具有杀菌作用,并且在连续14次传代后不易形成抗性。此外,这些化合物(在2x MI

A series of new 6-substituted-4-(3-bromophenylamino)quinazoline derivatives that may function as irreversible inhibitors of epidermalgrowthfactorreceptor (EGFR) and human epidermalgrowthfactorreceptor (HER-2) tyrosine kinases have been prepared. These inhibitors have, at the C-6 position, butynamide, crotonamide, and methacrylamide Michael acceptors bearing water-solublilizing substituents. These
