Febrifugine is an alkaloid isolated from Dichroa febrifuga Lour as the active component against Plasmodium falciparum. Strong liver toxicity has precluded febrifugine as a potential clinical drug. In this study novel febrifugine analogues were designed and synthesized. Lower toxicity was achieved by reducing or eliminating the tendency of forming chemically reactive and toxic intermediates and metabolites
Febrifugine 是从 Dichroa febrifuga Lour 中分离出来的一种生物碱,作为对抗恶性疟原虫的活性成分。强肝毒性使得常古碱无法作为潜在的临床药物。在这项研究中,设计并合成了新型常古碱类似物。较低的毒性是通过减少或消除形成化学反应性和有毒中间体和代谢物的趋势来实现的。在体外评估合成化合物对氯喹敏感(D6)和氯喹抗性(W2)恶性疟原虫菌株的功效,并在新鲜分离的大鼠肝细胞中评估潜在的细胞毒性。最佳化合物的 IC(50) 优于其母体化合物常新。值得注意的是,这些化合物的毒性也比常古碱低 100 多倍。这些化合物以及潜在的设计原理可能有助于发现和开发新的抗疟药物。
