Spirocyclopentanone–anthracene adducts, novel antimalarial agents, have been synthesized by employing the racemic and the optically active dimethyl itaconate–anthracene adducts in a reaction with piperine via tandem Michael addition–Dieckmann condensation reactions as the key steps. All adducts exhibited antimalarial activity with IC50 values of 3.4–4.7 μg/mL, and importantly displayed non-cytotoxicity
螺环戊酮-蒽加合物,新型抗疟剂,是通过将外消旋和旋光性衣康酸二甲基衣康酸酯-蒽加合物与胡椒碱反应,通过串联迈克尔加成反应-狄克曼缩合反应合成的。所有加合物均表现出抗疟活性,IC 50值为3.4–4.7μg/ mL,重要的是对Vero细胞无细胞毒性。
