Compounds of formula (I): CHEM in which Y is a halogen atom, preferably a bromine atom, each of R1 and R2 is a hydrogen atom or an acyl radical of the formula X - @ - , in which X is a C1-6 alkyl group or a carboxy group of the formula HO-@-Z- in which Z is a branched- or straight-chain alkylene radical having from 1 to 4 carbon atoms in the chain, with the proviso that R1 and R2 are not simultaneously hydrogen atoms or acetyl groups; are useful in the treatment of viral infection, particularly those caused by herpes viruses.
