A small library of 2-[(1H-indol-3-yl)methyl]-5-(alkylthio)-1,3,4-oxadiazoles was prepared, starting from indole-3-acetic acid methyl ester and its 5-methyl-substituted derivative. The synthetic route involved the formation of intermediate hydrazides, their condensation with carbon disulfide, and intramolecular cyclization to corresponding 5-[(1H-indol-3-yl)methyl]-1,3,4-oxadiazole-2(3H)-thiones. The
将2小库- [(1- ħ -吲哚-3-基)甲基] -5-(烷硫基)-1,3,4-恶二唑的制备,从吲哚-3-乙酸甲酯和其5-开始甲基取代的衍生物。合成路线包括中间体酰肼的形成,它们与二硫化碳的缩合,以及分子内环化为相应的 5-[(1 H -indol-3-yl)methyl]-1,3,4-oxadiazole-2(3 H ) -硫酮。后者随后被 S-烷基化,对于酯衍生物,它们进一步水解成相应的羧酸。所有 5-[(1 H -indol-3-yl)methyl]-1,3,4-oxadiazole-2(3 H)-硫酮和它们的 S-烷基化衍生物随后被筛选在体外和体内的保护作用。揭示了吲哚环上的甲基取代和含有巯基的化合物上的丙基、丁基或苄基取代,以保护弗里德赖希共济失调成纤维细胞免受由 γ-谷氨酰半胱氨酸合成酶抑制剂丁硫氨酸亚砜亚胺诱导的谷胱甘肽耗竭的影响。两种活性化合物也可重复地增加暴露于胡桃诱导的氧化应激的秀丽隐杆线虫的存活率。
