  联苯咪唑衍生物作为有效的抗真菌剂的发现：设计，合成和构效关系研究

  摘要：

  真菌感染由于其高发病率和高死亡率而已成为严重的医学问题。我们描述了一系列新型联苯咪唑衍生物的发现和构效关系研究（SAR），这些衍生物对白色念珠菌和新隐球菌具有优异的抗真菌活性。最有前途的化合物12f – g和19a – b表现出出色的活性，最小抑菌浓度（MIC）值在0.03125–2μg/ mL的范围内。初步机理研究表明，化合物12g的有效抗真菌活性源于对白色念珠菌中CYP51的抑制作用。。此外，化合物12g和19b对多种人细胞色素P450同工型表现出低抑制特性。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。
