In an ongoing effort to discover an effective, topical, dual‐function, non‐surfactant contraceptive vaginal microbicide, a novel series of 2,2′‐disulfanediylbis(3‐(substituted‐1‐yl)propane‐2,1‐diyl) disubstituted‐1‐carbodithioates were designed by using a bioisosterism approach. Thirty‐three compounds were synthesized, and interestingly, most demonstrated multiple activities: they were found to be
为了不断发现有效,局部,双重功能,非表面活性剂的避孕阴道杀菌剂,开发了一系列新的2,2'-二

生物立体异构方法设计了二取代-1-碳二
硫代盐。合成了33种化合物,有趣的是,大多数化合物具有多种活性:在最小有效浓度为1-0.001%的情况下,它们是杀精子剂,在对药物敏感和耐药的毛滴虫菌株中的最小抑菌浓度(MIC)范围为: 10.81-377.64和10.81-754.14μ中号,分别和杀真菌在MIC 7.93-86.50μ中号。还发现这些化合物在体外对人宫颈(HeLa)上皮细胞和阴道菌群(
