Thirty one derivatives were prepared from the natural alkaloids haemanthamine (1), haemanthidine (2) and 11-hydroxyvittatine (3). They were evaluated for their in vitro antimalarial activity against chloroquine-sensitive strains of Plasmodium falciparum and some structure–activity relationships were outlined. For haemanthamine derivatives having a methoxy group at C-3, the presence of a free hydroxyl
三十酮衍生物是从天然生物碱haemanthamine(制备1),haemanthidine(2)和11-hydroxyvittatine(3)。他们评估了它们对恶性疟原虫氯喹敏感菌株的体外抗疟活性,并概述了一些构效关系。对于在C-3处具有甲氧基的血红花胺衍生物,对于C-11活性而言,在C-11处存在游离羟基是重要的。C-1–C-2处的双键也起重要作用,以实现良好的抑制活性。在C-3和C-11处具有两个烟酸酯基的化合物35是活性最高的化合物,IC 50 = 0.8±0.06μM。
