To further explore the structure activity relationships (SARs) of our previously discovered antifungal lead compound (1), a series of biphenyl imidazole analogues were designed, synthesized and evaluated for their in vitro antifungal activity. Many of the synthesized compounds showed excellent activity against Candida albicans and Candida tropicalis. Among these compounds, 2-F substituted analogue
为了进一步探索我们先前发现的抗真菌先导化合物(1)的结构活性关系(SAR),设计,合成和评估了一系列联苯咪唑类似物的体外抗真菌活性。许多合成的化合物对白色念珠菌和热带念珠菌具有优异的活性。在这些化合物中,2-F取代的类似物12m在体外对白色念珠菌,新孢菌,烟曲霉和耐氟康唑的C. alb表现出最显着的活性。菌株,其活性优于或可比参比药物氟康唑和伊曲康唑。值得注意的是,化合物12m对多种人细胞色素P450同工型显示出低抑制特性,并且对哺乳动物A549细胞和U87细胞显示出低毒性。在这项研究中建立的SAR和绑定模式将有助于进一步优化潜在客户。
