It has been found that 1,5-anhydrohexitol nucleoside analogues, wherein a 4-substituted-2,3,4-trideoxy-1,5-anhydrohexitol is coupled via its 2-position to the heterocyclic ring of a pyrimidine or purine base, exhibit remarkable anti-viral properties against herpes viruses, pox viruses and related viruses. The new nucleoside analogues are represented by the general formula I <IMAGE> (I) wherein B is a heterocyclic ring derived from a pyrimidine or purine base, X represents H, N3, F, Cl, Br, I, amino, -NHR2, -N(R2)2, -OR2, -SR2 or CN, R1 and R2 are the same or different and hydrogen, alkyl, acyl or phosphate groups are represented, or wherein X is hydrogen and a double bond is situated between the 3- and 4- position of the 1,5-anhydrohexitol ring. Pharmaceutically acceptable salts and esters thereof are included.
