showed IC50 values of 0.9, 2.0 and 2.7 against 3D7 (chloroquine sensitive), Dd2 and Indo (chloroquine resistant) strains of Plasmodium falciparum respectively. Moreover, 27 and 11, which exhibited selectivity indices of 40 and >111 were also found to be nontoxic to the HeLa cell line. Microscopic studies revealed that the rings and trophozoites obtained from the 27 and 11 (an octupolar tristyrylbenzene
首次系统评价了天然产物和二/三苯乙烯基苯的羟基二苯乙烯家族的抗疟原虫活性。使用修饰的Knoevenagel-Perkin-脱羧化-Heck序列,从容易获得的起始材料(即,羟基苯甲醛-苯乙酸-芳基卤化物)中快速合成了27个不同取代的羟基类苯乙烯类化合物的文库。评价了这些化合物对三种不同菌株恶性疟原虫的体外抗血浆活性。值得注意的是,4,4'4'' - ((1- Ë,1' ë,1'' Ë) -苯-1,3,5-三基三(乙烯-2,1-二基))三(2,6-二甲氧基苯酚)(27),一种八极类芪,对3D7(对氯喹敏感),Dd2和Indo(对氯喹抗性)菌株的IC 50(μM)值分别为0.6、0.5和1.36,而二苯乙烯基苯(11)的IC 50值为0.9、2.0和2.7。的恶性疟原虫分别。此外,还发现选择性指数为40和> 111的27和11对HeLa细胞系无毒。显微镜研究表明,从27和11获得的环和滋养体
