A total of 80 new 2-methyl-6-ureido-4-quinolinamides were synthesized and evaluated for their antimalarial activity. Several analogs elicited the antimalarial effect at MIC of 0.25 mg/mL against the chlooquine-sensitive P. falciparum strain. The IC50 values of the active compounds were observed to be in ng/mL range and two of the analogs have better IC50 value than the standard chloroquine. In the
总共合成了80种新的2-甲基-6-脲基-4-喹啉酰胺,并评估了它们的抗疟活性。几种类似物在MIC为0.25 mg / mL时对氯喹敏感的恶性疟原虫菌株产生抗疟作用。观察到活性化合物的IC 50值在ng / mL范围内,并且两个类似物的IC 50值均优于标准氯喹。在体内对耐Mdr CQ的约氏疟原虫N67 /尼日尔疟原虫然而,在第7天,没有一种化合物能完全抑制寄生虫病。其中一种化合物对几种细菌显示出显着的抗菌作用,并且比标准药物庆大霉素高出许多倍。
