important flaviviruses. It has a serine protease which is important for viral replication and this enzyme constitutes a suitable target for new anti-retroviral drugs. Herein we disclose a series of amide and ester peptide mimetic inhibitors of serine proteases, all of them obtained via coupling reactions of isomannide derivatives with N-protected amino acids. The arginine derivative 19 showed 45% of inhibition
丙型肝炎病毒(HCV)是最重要的黄病毒之一。它具有丝氨酸蛋白酶,这对于病毒复制很重要,并且该酶构成新的抗逆转录病毒药物的合适靶标。本文中,我们公开了一系列丝氨酸蛋白酶的酰胺和酯肽模拟物抑制剂,它们都是通过异甘露糖衍生物与N-保护的氨基酸的偶联反应而获得的。精氨酸衍生物19在100μM浓度下抑制了NS3 / 4A丝氨酸蛋白酶的45%,分子模型研究表明19与该酶的活性位点相互作用。
