A series of ten novel hybrids from benzimidazole and pentamidine were prepared using a short synthetic route. Each compound was tested in vitro against the protozoa Trichomonas vaginalis, Giardia lamblia, Entamoeba histolytica, Leishmania mexicana, and Plasmodium berghei, in comparison with pentamidine and metronidazole. Some analogues showed high bioactivity in the low micromolar range (IC(50)<1 microM)
使用短合成路线制备了十种来自苯并咪唑和喷他idine的新型杂种。与喷他idine和甲硝唑相比,每种化合物均在体外针对阴道毛滴虫,兰氏贾第鞭毛虫,溶血性变形杆菌,墨西哥利什曼原虫和伯氏疟原虫进行了测试。一些类似物对前四个原生动物在低微摩尔范围(IC(50)<1 microM)中显示出高生物活性,这使它们比任何一个标准都具有更强的效力。1,5-双[4-(5-甲氧基-1H-苯并咪唑-2-基)苯氧基]戊烷(2)对G的效力分别高3到9倍。兰比兰甲硝唑和戊tam分别。该化合物分别比喷他idine具有23.,108-和13-倍的活性,其对阴道隐孢子虫,溶组织性大肠杆菌和墨西哥乳杆菌具有更高的活性。
