alpha, 2 beta, 3 beta, 4 alpha)-4-amino-1,2,3-cyclopentanetriol (7). Also prepared from the same starting material were the related hypoxanthine (4), guanine (5), and 2,6-diaminopurine (6) analogues. Compounds 3-6 were evaluated for antiviral activity against a large number of viruses with marked activity being observed for 3 towards vaccinia virus, human cytomegalovirus, vesicular stomatitis virus, parainfluenza
从(+/-)-(1 alpha,2 beta,3 beta,4 alpha)的2,3-O-异亚丙基衍生物开始,分三步制备(+/-)-5'-诺拉霉素(3) -4-氨基-1,2,3-环戊三醇(7)。同样由相同的原料制得的是相关的次黄嘌呤(4),鸟嘌呤(5)和2,6-二氨基嘌呤(6)类似物。评估化合物3-6对大量病毒的抗病毒活性,并观察到3对牛痘病毒,人巨细胞病毒,水疱性口炎病毒,副流感(3型)病毒,麻疹病毒,呼吸道合胞病毒,呼肠孤病毒(类型)具有显着活性1)以及arenaviruses Junin和Tacaribe。没有一种化合物对抗病毒研究中使用的宿主细胞单层显示出细胞毒性。已经发现3和6都是S-腺苷-L-高半胱氨酸水解酶(AdoHcy水解酶)的抑制剂,这很可能说明了它们的抗病毒活性。抑制AdoHcy水解酶代表了应进行的人类巨细胞病毒药物设计的新方法。同样,应进一步检查3的活性,以治疗痘病毒
