leishmanicidal activity. The ester analogues (series B) were found to have a 1.5 to 5-fold reduced activity compared to their acidic counterparts. Cytotoxicity against mammalian mouse fibroblast 3 T3 cells was also evaluated and compared between the acid and its ester analogue. The reduction of antileishmanial activity and loss of toxicity in the newly developed THTT ester derivative indicates that
合成了四个系列的杂环化合物,即四氢-2 H -1,3,5-噻二嗪硫酮衍生物,收率良好至极佳,并筛选了它们对利什曼原虫(promastigotes)的体外抗菌活性。 与标准喷他idine(IC 50)相比,大多数化合物在IC 50 = 15.48–39.36μM范围内显示出显着的抗菌活性。 = 14.95μM)。构效关系表明,N-3和N-5取代基对杀菌活性具有关键作用。发现酯类似物(系列B)与酸性类似物相比,活性降低了1.5至5倍。还评估了对哺乳动物小鼠成纤维细胞3 T3细胞的细胞毒性,并在该酸及其酯类似物之间进行了比较。新开发的THTT酯衍生物的抗菌活性降低和毒性降低表明这些化合物可以用作生产有效抗菌酯前药的模板研究。
