The alpha- and beta-D-lyxofuranosyl analogues of the naturally occurring nucleosides have been synthesized and their antiviral properties examined. The alpha anomers were prepared by glycosylation of purine and pyrimidine aglycons with tetra-O-acetyl-alpha-D-lyxofuranose, followed by removal of the blocking groups. The beta anomers were obtained by sequential oxidation and reduction of 3',5'-O-(1,1
天然存在的核苷的α-和β-D-呋喃呋喃糖基类似物已经合成,并检查了它们的抗病毒特性。通过将嘌呤和嘧啶糖苷配基与四-O-乙酰基-α-D-lyxofurananose糖基化,然后除去保护基团来制备α端基异构体。通过依次氧化和还原3',5'-O-(1,1,3,3-四异丙基二硅氧烷-1,3-二基)-β-Dx呋喃呋喃糖基核苷来获得β端基异构体。测试了呋喃呋喃糖基核苷对多种RNA和DNA病毒的活性以及对细胞生长的抑制作用。一种化合物9-α-D-lyxofuranosyladenine在体外和体内均显示出对1型和2型单纯疱疹病毒的活性。
