A number of mono- and bicyclic endoperoxides were prepared and tested for antimalarial activity in search of a simplified analogue of the 5-oxygen-substituted 1,2,4-trioxane ring structure of the naturally occurring antimalarial qinghaosu. The compounds were assayed in an in vitro system for antimalarial activity against chloroquine-susceptible and chloroquine-resistant strains of P. falciparum. The
为了寻找天然抗疟药青蒿素的 5-氧取代 1,2,4-三恶烷环结构的简化类似物,制备了许多单环和双环内过氧化物并测试其抗疟活性。在体外系统中测定了这些化合物对恶性疟原虫的氯喹敏感和氯喹抗性菌株的抗疟活性。该试验中活性最强的化合物是 2-[((丁氧基)-羰基)oxy]-1,1,10-trimethyl-6,9-epidioxy-delta 7-octalin (17a),其 IC50 为 100,并且分别为 57 ng/mL。相比之下,青蒿素的平均 IC50 小于 3.4 ng/mL。
