Nucleoside analogues play an important role in antiviral, antibacterial and antineoplastic chemotherapy. Herein we report the synthesis, structural characterization and biological activity of some 4′-C-methyl- and -phenyl dioxolane-based nucleosides. In particular, α and β anomers of all natural nucleosides were obtained and characterized by NMR, HR-MS and X-ray crystallography. The compounds were
核苷类似物在抗病毒、抗菌和抗肿瘤化疗中发挥重要作用。在此,我们报告了一些基于 4'-C-甲基和 -苯基二氧戊环的核苷的合成、结构表征和生物活性。特别是,获得了所有天然核苷的 α 和 β 端基异构体,并通过 NMR、HR-MS 和 X 射线晶体学进行了表征。测试了这些化合物对一些有代表性的人类致病真菌、细菌和病毒的抗菌活性。在多种人类癌细胞系中评估了抗肿瘤活性。尽管大多数化合物表现出不显着的活性,但 23α 微弱地抑制了 HIV-1 的增殖。此外,22α 和 32α 表现出残留的抗肿瘤活性,有趣的是与非自然 α 构型有关。
