system using the model virus expressing recombinant HCV envelopes, E1 and E2. Now, we disclosed dimeric hydrolysable tannin oenothein B (1) from MeOH extract of Oenothera erythrosepala as an active principle for inhibition of HCV invasion and its potency was almost the same as that of monomeric hydrolysable tannin, tellimagrandin I (2). Furthermore, by use of stereoselectively prepared 1-β- and 1-α-O-methyl
已发现丙型肝炎病毒(HCV)的包膜蛋白E1和E2对HCV的入侵至关重要。因此,我们使用表达
重组HCV包膜E1和E2的模型病毒,通过测定系统寻找抗HCV入侵的
抑制剂。现在,我们公开了来自月见草红景天的MeOH
提取物的二聚体可
水解丹宁Oenothein B(1)作为抑制HCV入侵的有效原理,其功效几乎与单体可
水解丹宁(tellimagrandin I)相同(2)。此外,通过使用立体选择性制备的1-β-和1-α- O-甲基tellmagrandin Is(4和5),引入甲基部分的成1-羟基2澄清导致略微还原活性和β异构体显露出比α-一个稍微更强的活性。
