activity against HBV; by contrast, some related salicyloylanilides show a narrower spectrum of activity. The ADME properties of 3 are similar to 1; viz., the O-acetate is an effective prodrug, and the O-aryl glucuronide is a major metabolite. The QSAR study shows a good correlation of observed EC(90) for intracellular virions with thiazolide structural parameters. Finally we discuss the mechanism of action
我们报告了多种噻唑烷 [即 2-羟基芳酰基-N-(噻唑-2-基)酰胺] 对抗乙型肝炎病毒复制的合成和活性,并对我们的结果进行了 QSAR 分析。原型噻唑啉硝唑尼特 [2-羟基苯甲酰基-N-(5-硝基噻唑-2-基)酰胺,NTZ] 1 是一种广谱抗感染剂,可有效对抗厌氧细菌、病毒和寄生虫。相比之下,2-羟基苯甲酰-N-(5-氯噻唑-2-基)酰胺 3 是一种新型、有效、选择性的乙型肝炎复制抑制剂 (EC(50) = 0.33 μm),但对厌氧菌无活性。几种 4'- 和 5'-取代的噻唑化物对 HBV 显示出良好的活性;相比之下,一些相关的水杨酰苯胺的活性范围更窄。3 的 ADME 属性与 1 类似;即,O-乙酸酯是一种有效的前药,O-芳基葡糖苷酸是主要代谢物。QSAR 研究显示观察到的 EC(90) 与噻唑啉结构参数的细胞内病毒粒子具有良好的相关性。最后,我们讨论了与当前结果相关的噻唑化物的作用机制。
