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: 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 are each as defined above; phenyl, phenyl C.sub.1-3 alkoxy or phenyl C.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 is 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. The majority of the compounds are novel.
式(I)的化合物中,其中n为0、1或2;R.sup.1和R.sup.2,可能相同也可能不同,分别代表一个或多个环取代基,可选自:羟基、卤素、氰基、硝基、C.sub.1-6烷基、C.sub.3-6环烷基或C.sub.1-6烷氧基(其中烷基或环烷基基团可能可选择地被一个或多个取代基取代,取代基可选自卤素原子和羟基);--NR.sup.4 R.sup.5,其中R.sup.4和R.sup.5可能相同也可能不同,分别代表氢或C.sub.1-6如上所定义的烷基;苯基、苯基C.sub.1-3烷氧基或苯基C.sub.1-3烷基,其中苯基可能可选择地被一个或多个取代基独立选择自C.sub.1-6烷基、C.sub.1-6烷氧基、羟基、硝基、卤素和氨基取代;和--CO.sub.2 H或--COR.sup.7,其中R.sup.7为C.sub.1-6烷基或C.sub.3-6环烷基;R.sup.3为氢或C.sub.1-4烷基;以及它们的酯、盐和其他生理功能衍生物,显示出抗病毒药物活性,例如对抗HIV。大多数化合物都是新颖的。
