Compounds of formula (I) wherein n is 0, 1 or 2; and R.sup.1 and R.sup.2, which may be the same or different, each represent one or more ring substituent(s) selected from: hydrogen, hydroxy, halogen, cyano, nitro, C.sub.1-6 alkyl, C.sub.3-6 cycloalkyl or C.sub.1-6 alkoxy (where the alkyl or cycloalkyl moiety may be optionally substituted by one or more substituents selected from halogen atoms and hydroxyl groups); --NR.sup.4 R.sup.5 where R.sup.4 and R.sup.5, which may be the same or different, each represent hydrogen or C.sub.1-6 alkyl; --S(O).sub.m R.sup.6, where m is 0, 1, 2 or 3 and R.sup.6 represents hydrogen, C.sub.1-6 alkyl or C.sub.3-6 cycloakyl; --SO.sub.2 NR.sup.4 R.sup.5 where R.sup.4 et R.sup.5 are each as defined above; phenyl, phenylC.sub.1-3 alkoxy or phenylC.sub.1-3 alkyl where the phenyl group may be optionally substituted by one or more substituents independently selected from C.sub.1-6 alkyl, C.sub.1-6 alkoxy, hydroxy, nitro, halogen and amino; and --CO.sub.2 H or --COR.sup.7 where R.sup.7 is C.sub.1-6 alkyl or C.sub.3-6 cycloalkyl; R.sup.3 represents hydrogen or C.sub.1-4 alkyl; and esters, salts and other physiologically functional derivatives thereof; show activity as antiviral agents, for example against HIV. Certain of the compounds are novel.
