1,5-Anhydrohexitol nucleoside analogues represented by the general formula I: ##STR1## wherein the hexitol has the D-configuration and the carbon atom on which the base moiety and the X substituent stand both have the (S)-configuration and further wherein: B is a heterocyclic ring selected from the group consisting of pyrimidine and purine bases; and X is hydrogen, azido, F, Cl, Br, I, amino, --NHR.sup.2, --N(R.sup.2).sub.2, --OR.sup.2, --SR.sup.2, or CN; wherein R.sup.1 and R.sup.2 are the same or different and are selected from the group consisting of hydrogen, substituted or unsubstituted C.sub.1 -C.sub.20 alkyl, substituted or unsubstituted C.sub.1 -C.sub.20 alkenyl, aroyl, C.sub.1 -C.sub.20 alkanoyl, and phosphoryl. These nucleoside analogues are useful as antiviral agents against herpes simplex virus, vaccina virus, or varicella zoster virus. The definition of the X group should include --N(R.sup.2).sub.2 instead of --N(N.sup.2).sub.2.
1,5-去水己糖核苷类似物的一般式I如下:##STR1## 其中,己糖具有D构型,碳原子上的碱基基团和X取代基都具有(S)构型,进一步地:B是从嘧啶和嘌呤碱基组成的杂环环;X是氢、叠氮、F、Cl、Br、I、氨基、-NHR.sup.2、-N(R.sup.2).sub.2、-OR.sup.2、-SR.sup.2或-CN;其中,R.sup.1和R.sup.2相同或不同,选自氢、取代或未取代的C.sub.1-C.sub.20烷基、取代或未取代的C.sub.1-C.sub.20烯基、芳酰、C.sub.1-C.sub.20烷酰和磷酰。这些核苷类似物可用作抗病毒剂,用于对抗单纯疱疹病毒、牛痘病毒或水痘带状疱疹病毒。X组的定义应包括-N(R.sup.2).sub.2而不是-N(N.sup.2).sub.2。
