4-methyl-3',4'-di-O-(-)-camphanoyl-(+)-cis-khellactone (4-methyl DCK) analogs (7a-d) with different alkyl substituents at the 2'-position were synthesized and evaluated for inhibition of HIV-1 replication in H9 lymphocytes. 2'-Methyl-2'-ethyl-4-methyl DCK (7b) was more potent (EC(50)=0.22 microM, TI>175) than the other three compounds (7a, 7c, and 7d), but significantly less potent than 4-methyl DCK (2, EC(50)=0
四个4-甲基-3',4'-二-O-(-)-樟脑酰基-(+)-顺式-甲壳酮(4-甲基DCK)类似物(7a-d),其在2'-位具有不同的烷基取代基合成并评估其对H9淋巴细胞中HIV-1复制的抑制作用。2'-甲基-2'-乙基-4-甲基DCK(7b)比其他三种化合物(7a,7c和7d)更有效(EC(50)= 0.22 microM,TI> 175)效力高于4-甲基DCK(2,EC(50)= 0.0059 microM,TI> 6600)。生物测定结果表明,2'取代基对抗HIV活性具有很强的影响,在2'-位置的宝石-二甲基取代比较大的烷基取代基或氢原子更可取。
