Two series of 5′‐triphenylmethyl (trityl)‐substituted thymidine derivatives were synthesized and tested against Leishmania infantum axenic promastigotes and amastigotes. Several of these compounds show significant antileishmanial activity, with IC50 values in the low micromolar range. Among these, 3′‐O‐(isoleucylisoleucyl)‐5′‐O‐(3,3,3‐triphenylpropanoyl)thymidine displays particularly good activity
合成了两个5'-三苯甲基(三苯甲基)取代的胸腺嘧啶衍生物系列,并针对婴儿利什曼原虫的轴突前鞭毛体和变形虫进行了测试。这些化合物中的几种显示出显着的抗菌活性,IC 50值在低微摩尔范围内。其中,3'- O-(异亮环烯基)-5'- O-(3,3,3-三苯基丙酰基)胸苷对细胞内的变形虫表现出特别好的活性。在三苯甲基胸腺嘧啶脱氧核苷的存在下进行的表征寄生虫细胞死亡的性质的测定表明,在细胞死亡过程中,线粒体跨膜电位发生了显着变化,超氧化物浓度增加,DNA降解也显着减少。结果表明,线粒体核酸酶LiEndoG是该化合物家族作用的靶标。
