Plasmodium falciparum parasites. Many of these derivatives were highly efficacious; carboxylate ester 9f, carbamate ester 10a, and sulfonate ester 12a had antimalarial potency similar to that of artemisinin, and carboxylate esters 9b and 9d, carbamate esters 10b and 10c, and phosphate esters 11a-c had antimalarial potency up to 7 times higher than that of artemisinin. Several of these most active analogs
设计并合成了新的外消旋三环三恶烷醇3,作为临床上有用的四环抗疟青蒿素的结构简单类似物。可以轻松制备一系列20种醇3的酯和醚衍生物,而不会破坏基本的三恶烷体系。在体外针对抗氯喹和氯喹敏感的恶性疟原虫疟原虫评估了每种衍生物的化学结构-抗动物活性。这些衍生物中的许多是高效的。羧酸酯9f,氨基甲酸酯10a和磺酸酯12a的抗疟药功效与青蒿素相似,而羧酸酯9b和9d,氨基甲酸酯10b和10c以及磷酸酯11a-c的抗疟药功效比青蒿素高7倍。青蒿素 这些最活跃的类似物中的几个(例如,
