In order to study the structure-activity relationships of dioxolane nucleosides as potential anti-HIV agents, various enantiomerically pure dioxolane-pyrimidine nucleosides have been synthesized and evaluated against HIV-1 in human peripheral blood mononuclear cells. The enantiomerically pure key intermediate 8 has been synthesized in nine steps from 1,6-anhydro-D-mannose (1), which was condensed with

An asymmetric synthesis leading to the enantiomericallypure dioxolane-T has been achieved and its crystalstructure has been determined and compared to the previously reported racemate. (−)-(1′R,4′R )-Dioxolane-T was found to have potent and selective anti-HIV activity in primary human lymphocytes.

An asymmetric process for the preparation of enantiomerically pure β-D-(-)-dioxolane-nucleosides. The enantiomerically pure dioxolane nucleosides are active HIV agents, that are significantly more effective than the prior prepared racemic mixtures of the nucleosides. The anti-viral activity of the compounds is surprising in light of the generally accepted theory that moieties in the endo conformation, including these dioxolanes, are not effective antiviral agents. The toxicity of the enantiomerically pure dioxolane nucleosides is lower than that of the racemic mixture of the nucleosides, because the nonnaturally occurring α-isomer is not included. The product can be used as a research tool to study the inhibition of HIV in vitro or can be administered in a pharmaceutical composition to inhibit the growth of HIV in vivo.
制备对映体纯的β-D-(-)-二氧戊环核苷的不对称工艺。对映体纯的二氧戊环核苷是一种活性艾滋病毒制剂,其效果明显优于之前制备的核苷外消旋混合物。根据普遍接受的理论,内构象的分子(包括这些二氧戊环)不是有效的抗病毒剂,因此这些化合物的抗病毒活性令人惊讶。对映体纯的二氧戊环核苷的毒性低于核苷外消旋混合物,因为其中不包括非天然存在的α-异构体。该产品可用作研究工具,研究体外对 HIV 的抑制作用,也可在药物组合物中施用,抑制 HIV 在体内的生长。
