Two series of N,N′-diphenyl-benzamidines were synthesized as part of a study to search potential new drugs with antileishmanial activity. These compounds were obtained by anilides in PCl5 halogenation reaction with generation in situ of the corresponding benzimidoyl chlorides, and subsequently treatment with adequate anilines. The series I showed expressive results of antileishmanial activity, highlighted
作为研究的一部分,合成了两个系列的N,N'-二苯基-苯甲m,以寻找具有抗菌活性的潜在新药。这些化合物是通过在PCl 5卤化反应中通过酰胺化并原位生成相应的苯二甲酰氯而得到的,然后用适当的苯胺处理。该系列我展示antileishmanial活性的表达的结果,强调了化合物9A与IC 50 = 81.28μM(日志IC 50 = 1.91μM)针对利什曼原虫恰加斯利什,8E与IC 50 = 26.30(日志IC 50 = 1.52μM)对巴西利什曼原虫。根据SAR研究的结果(系列I),从Craig二维图计划了系列II,在其中可能发现有效化合物9v和9j,IC 50 = 12.60μM(log IC 50 = 1.10) μM)和13.00μM(log IC 50 = 1.11μM),分别针对亚马逊利什曼原虫。从SAR和QSAR研究获得的结果表明,当环中的电子供体基团连接到in基碳上
