have precluded febrifugine as a potential clinical drug. As part of an ongoing malaria chemotherapy project, novel febrifugine analogues were designed and synthesized. Lower toxicity of these newly designed compounds was achieved by reducing or eliminating the tendency to form chemically reactive and toxic intermediates. New compounds possess excellent in vivo antimalarial activity and most of them become
Febrifugine 是从 Dichroa febrifuga 中分离出来的一种生物碱,是抗恶性疟原虫的活性成分。不良副作用已排除 febrifugine 作为潜在的临床药物。作为正在进行的疟疾化学疗法项目的一部分,设计并合成了新型发热剂类似物。这些新设计的化合物的毒性较低是通过减少或消除形成化学反应性和有毒中间体的趋势来实现的。新化合物具有优异的体内抗疟活性,其中大多数变得比天然产物 febrifugine 毒性更小。其中一些化合物的治疗指数比退热药和常用的抗疟药氯喹高十倍以上。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。
