ribo- and 2′-deoxyribobenzimidazoles (40–55% vs 60–90%). The compounds obtained were tested against the herpes simplex virus type 1, by using the Vero E6 cells. 5-Methoxy-4,6-difluoro-1-β-d-(2′-deoxy-2′-fluoroarabinofuranosyl)benzimidazole did not show any antiviral activity, when used in nontoxic concentration. All other nucleosides proved to exhibit a selective antiherpes activity. In contrast, it
摘要 含有4,6-二氟-,4,5,6-三氟-,5-氟-6-甲氧基和5-甲氧基的1-(2'-脱氧-2'-氟-β- d-阿拉伯呋喃糖基)苯并咪唑采用嘌呤核苷磷酸化酶催化化学酶法合成了-4,6-二氟苯并咪唑片段。不出所料,与核糖和2'-脱氧核糖苯并咪唑类化合物的合成相比,酶促合成核苷的目标化合物产率较低(40-55%vs 60-90%)。通过使用Vero E6细胞,对获得的化合物针对1型单纯疱疹病毒进行了测试。5-甲氧基-4,6-二氟-1-β- d当以无毒浓度使用时,-(2'-脱氧-2'-氟阿拉伯呋喃糖基)苯并咪唑没有显示任何抗病毒活性。已证明所有其他核苷均表现出选择性抗疱疹活性。相反,已表明,二取代和三取代衍生物的苯并咪唑-β - d-阿拉伯呋喃糖苷以及在苯环的4-6位具有取代基的化合物,以及未取代的化合物均不能通过酶促糖基化反应合成。1-(β- d通过的糖基化得到-Arabinofuranosyl)苯并咪唑Ñ
