The synthesis of a new series of S-substituted acetamides derivatives of 5-[(2-amino-1,3-thiazol-4-yl)methyl]-1,3,4-oxadiazol-2-thiol were synthesized and evaluated for enzyme inhibition study along with cytotoxic behavior. Ethyl 2-(2-amino-1,3-thiazol-4-yl)acetate was converted to corresponding acid hydrazide by hydrazine hydrate in ethanol. The reflux of acid hydrazide with carbon disulfide resulted
合成了一系列新的 5-[(2-amino-1,3-thiazol-4-yl)methyl]-1,3,4-oxadiazol-2-thiol 的 S-取代乙酰胺衍生物并评价了酶抑制研究以及细胞毒性行为。2-(2-氨基-1,3-噻唑-4-基)乙酸乙酯在乙醇中通过水合肼转化为相应的酰肼。酰肼与二硫化碳的回流产生5-[(2-氨基-1,3-噻唑-4-基)甲基]-1,3,4-恶二唑-2-硫醇。不同的亲电子试剂是通过各自的苯胺(每个反应中一种)和 2-溴乙酰溴在水性介质中的反应合成的。通过将亲核 5-[(2-amino-1,3-thiazol-4-yl)methyl]-1,3,4-oxadiazol-2-thiol 与不同的乙酰胺亲电试剂(一个在其他),在 DMF 中使用 LiH 作为碱和活化剂。新合成化合物的结构是通过光谱技术如 1H NMR、13C NMR、EI MS 和元素分析推导出来的。通过体外抑制
