against both species, which make them significantly more potent than either standard. Compound 4 [2,5(6)-bis(trifluoromethyl)-1H-benzimidazole], was 14 times more active than albendazole against T. vaginalis. This compound (4) also showed moderate antimalarial activity against W2 and D6 strains of Plasmodium falciparum (5.98 and 6.12 microM, respectively). Studying further structure activity relationships
使用短合成路线制备了一系列具有各种5-和6-位生物等位取代基(-Cl,-F,-CF3,-CN),即1-7的2-(三氟甲基)-1H-苯并咪唑衍生物。与阿苯达唑和甲硝唑相比,每种类似物均在体外针对原虫贾第鞭毛虫和阴道毛滴虫进行了测试。几种类似物对这两个物种的IC50值均小于1 microM,这使其比任何一种标准都具有更高的效力。化合物4 [2,5(6)-双(三氟甲基)-1H-苯并咪唑]的活性比阿苯达唑高14倍。该化合物(4)对恶性疟原虫的W2和D6菌株也显示出中等的抗疟活性(分别为5.98和6.12 microM)。
