series of 15-membered azalide urea and thiourea derivatives has been synthesized and evaluated for their in vitro antimalarial activity against chloroquine-sensitive (D6), chloroquine/pyremethamine resistant (W2) and multidrug resistant (TM91C235) strains of Plasmodium falciparum. We have developed an effective automated synthetic strategy for the rapid synthesis of urea/thiourea libraries of a macrolide
合成了一系列15元氮杂内酰胺脲和硫脲衍生物,并评估了它们对恶性疟原虫的氯喹敏感性(D6),氯喹/乙胺嘧啶抗性(W2)和多药耐药性(TM91C235)菌株的体外抗疟活性。我们已经开发出一种有效的自动化合成策略,用于大环内酯支架的尿素/硫脲库的快速合成。使用溶液相策略合成化合物,总收率为50–80%。大多数合成的化合物具有抑制作用。前三种化合物对所有三种菌株的效力比阿奇霉素高30-65倍,阿奇霉素具有抗疟疾活性。
