e derivatives (4a–m) and their precursor 1-aryl-3-methyl-1H-pyrazole-4-carbonitriles (3a–m) were synthesized and evaluated as antileishmanials against Leishmania braziliensis and Leishmania amazonensis promastigotes in vitro. In parallel, the cytotoxicity of these compounds was evaluated on the RAW 264.7 cell line. The results showed that among the assayed compounds the substituted 3-chlorophenyl (4a)
一系列新的5-(1-芳基-3-甲基-1 H-吡唑-4-基)-1 H-四唑衍生物(4a – m)及其前体1-芳基-3-甲基-1 H-吡唑合成-4-腈(3a – m)并作为抗疟药对巴西利什曼原虫和亚马逊利什曼原虫前鞭毛体进行了评价。同时,在RAW 264.7细胞系上评估了这些化合物的细胞毒性。结果表明,在待测化合物中,取代的3-氯苯基(4a)(IC 50/24 h = 15±0.14μM)和3,4-二氯苯基四唑(4d)(IC 50 /24小时= 26±0.09μM)反对的最有力的L. braziliensis前鞭毛体,与参考药物喷他脒,其中提出IC 50 = 13±0.04μM。此外,4a和4d衍生物的细胞毒性低于喷他idine。然而,这些四唑衍生物(4)和吡唑-4-甲腈的前体(3)针对不同每种测试物种的和反对更有效的巴西利什曼原虫比亚马逊利什曼原虫。
