(+)-Deoxoartelinic acid (13), a new hydrolytically stable, water-soluble, and potent non-acetal-type antimalarial drug candidate, was successfully prepared from artemisinic acid by using sulfur ylide and photooxygenative cyclization in seven steps. This compound showed superior in vitro antimalarial activity against the chloroquine-resistant K1 strain of Plasmodium falciparum and higher suppression
(Y)-脱氧青蒿酸(13)是一种新的水解稳定,水溶性且有效的非乙缩醛类抗疟药物候选物,它是通过使用叶立德硫磺和光氧合环化七个步骤成功地从青蒿酸制备的。该化合物对恶性疟原虫的抗氯喹K1菌株具有优异的体外抗疟活性,并且在体内对沙巴氏疟原虫感染小鼠的抑制作用高于抗关节炎药物(98.7%)。(+)-去氧青蒿酸还显示出显着的稳定性,半衰期为258.66小时,在模拟的胃酸中比临床有用的蒿甲醚稳定23倍,并且溶解度提高,在水中的溶解度比青蒿素高4倍。
