A compound of formula I or a pharmaceutically acceptable salt thereof
where
-R₁ is hydrogen or methyl;
-X- is -CO- or -CH₂-;
-Y- is >CH-A or its vinylogous group >C=CH-CH₂-A,
wherein -A is a -NR₄R₅ group, where each R₄ and R₅, equal or different between them, is C₁-C₄-alkyl or a phenyl-substituted C₁-C₄-alkyl; or -A is the N-radical of a 5- or 6-membered, uncharged (i.e. neither quaternary nor zwitterionic) monocyclic ring, either aromatic or non-aromatic, said ring containing one N atom, two N atoms, three N atoms or an N/O pair of atoms, all other atoms in the ring being carbon, and said ring being optionally mono- or di-substituted by groups selected from C₁-C₄-alkyl, benzyl, 2-furanylmethyl and 2-thienylmethyl;
-R₂ is hydrogen or a radical C₁-C₄-alkyl, C₁-C₄-alkoxy, di-(C₁-C₄-alkyl)amino, nitro or halogen, said radical being attached at the 2, 3 or 4 substitution positions of the phenyl ring;
-R₃ is hydrogen, phenyl, C₁-C₁₀-alkyl, a C₃-C₁₀-alkenyl or alkynyl group with the double or triple bond non-adjacent to the O-C bond, -(CH₂CH₂O)n-H with n = 1, 2 or 3, -(CHOH)m-H with m = 2, 3 or 4, or -when X is CO-the radical I-bis where Y is defined as above.
