generally treated by Metronidazole and Fluconazole respectively. Poor vaginal efficacy, drug-resistance and non-spermicidal nature limit their use as topical microbicidal contraceptives. Bis(dialkylaminethiocarbonyl)disulfides (4–38) were designed as dually active, non-surfactant molecules capable of eliminating Trichomonas vaginalis and Candida strains as well as irreversibly immobilizing 100% human sperm
滴虫病和念珠菌病是最常见的致病性生殖道感染,通常分别用甲硝唑和氟康唑治疗。阴道功效差,耐药性和非杀精性限制了它们作为局部杀微生物避孕药的使用。双(二烷基胺硫代羰基)二硫化物(4 – 38)被设计为具有双重活性的非表面活性剂分子,能够消除阴道毛滴虫和念珠菌菌株,并且能够以不可细胞毒性的剂量立即不可逆地固定100%人类精子,对人类宫颈上皮细胞和体外阴道菌群。化合物12,16,17它们的活性是非氧化酚9,OTC阴道杀精子剂的50倍,并且化合物12和17在兔模型中显示出显着的体内活性。最有前途的化合物17由于具有更高的活性和安全性以及显着的体内滴虫杀菌活性,已显示出有望进一步发展为双刃阴道杀微生物剂。二硫化物基团的作用是由于化学修饰过程中杀精子活性的丧失而确立的(39 – 56)。这些二硫化物可能靶向存在于人精子和滴虫的细胞膜上的巯基,如游离巯基的荧光标记所示。
