  摘要：

  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。

  Structure–activity relationship study of phenylpyrazole derivatives as a novel class of anti-HIV agents

  摘要：

  The structure-activity relationship of phenylpyrazole derivative 1 was investigated for the development of novel anti-HIV agents. Initial efforts revealed that the diazenyl group can be replaced by an aminomethylene group. In addition, we synthesized various derivatives by the reductive amination of benzaldehydes with 5-aminopyrazoles and carried out parallel structural optimization on the benzyl group and the pyrazole ring. This optimization led to a six-fold more potent derivative 32j than the lead compound 1, and this derivative has a 3',4'-dichloro-(1,1'-biphenyl)-3-yl group. (C) 2013 Elsevier Ltd.
