have been synthesized, in which the 3'-diethylamino function of amodiaquine (AQ) is replaced by a 3'-tert-butylamino group and an aliphatic hydrocarbon entity is incorporated into the 5'-position of the 4'-hydroxyanilino side chain. Seven alkyl Mannich base derivatives were screened and found to be active against both chloroquine-sensitive and -resistant strains of Plasmodium falciparum in vitro. The propyl
合成了一系列新的4-氨基喹啉曼尼希碱衍生物,其中氨二喹(AQ)的3'-二乙基氨基官能团被3'-叔丁基氨基取代,脂族烃实体被引入5'- 4'-羟基苯胺基侧链的位置。筛选了七个烷基曼尼希碱衍生物,发现它们在体外对氯喹敏感和耐药的恶性疟原虫菌株均具有活性。发现丙基和异丙基烷基衍生物是活性最高的。因此,对这些衍生物进行了体内抗伯氏疟原虫菌株的测试,发现其活性比AQ高3倍,而与给药途径(口服或腹膜内)无关。
