derivatives, seselin (3) and (+/-)-cis-(4), (+)-cis- (5), and (+/-)-trans-dihydroseselin-3',4'-diol (7) were also tested for their in vitro anti-HIV activity. An optically pure compound, 3',4'-di-O-(-)-camphanoyl-(+)-cis-khellactone (16), showed potent inhibitory activity and remarkable selectivity against HIV replication. The EC50 value and in vitro therapeutic index (TI) of 16 are 4 x 10(-4) microM and
为了评估其抗HIV活性,合成了42种基于Suksdorfin(1)结构的二氢香豆素。这些合成衍生物包括3',4'-二-O-酰基-和3'-或4'-O-酰基-顺式-二氢芝麻素(8-21)和3',4'-反式-二氢芝麻素与O-酰基和/或在3'和4'位置(6、22-43)的O-烷基。还制备了两个4'-叠氮基(44、45)和三个4'-烷基酰胺基(46、48、49)衍生物。通过使用光学纯试剂,合成了三对非对映异构体,并将其分离为光学纯化合物(14、15、16、17、38、39)。塞斯林(3)和(+/-)-顺-(4),(+)-顺-(5)和(+/-)-反-二氢塞塞林3',4'与上述合成衍生物一起还测试了-二醇(7)的体外抗HIV活性。光学纯的化合物3',4' -di-O-(-)-camphanoyl-(+)-cis-khellactone(16)具有较强的抑制活性,并且对HIV复制具有明显的选择性。EC50值和体外治疗指数(TI)为16分别为4
