摘要

A compound of formula (I): or a tautomeric form thereof and/or a pharmaceutically acceptable salt thereof, and/or a pharmaceutically acceptable solvate thereof, wherein: A<1> represents a substituted or unsubstituted aromatic heterocyclyl group; A<2> represents a benzene ring having three optional substituents; A<3> represents a moiety of formula -(CH2)m-CH(OR<1>)- wherein R<1> represents substituted or unsubstituted alkyl, aryl, aralkyl or alkylcarbonyl and m represents an integer in the range of from 1 to 5, or A<3> represents a moiety of formula - (CH2)m-1-CH=C(OR<1>)- wherein R<1> and m are as defined above; R<2> represents OR<3> wherein R<3> represents hydrogen, alkyl, aryl or aralkyl or R<2> represents an aromatic heterocyclyl group or -NR<4>R<5> wherein R<4> and R<5> each independently represent hydrogen, alkyl or alkylcarbonyl or R<4> and R<5> together with the nitrogen atom to which they are attached form a heterocyclic ring, providing that R<2> represents an aromatic heterocyclyl group only when Y as defined below represents a bond ; X represents NR wherein R represents a hydrogen atom, an alkyl group, an acyl group, an aralkyl group wherein the aryl moiety may be substituted or unsubstituted, or a substituted or unsubstituted aryl group; Y represents CO or CS or a bond providing that Y represents a bond only when R<2> represents the above mentioned aromatic heterocyclyl group; and n represents an integer in the range of from 2 to 6; a process for preparing such a compound, a composition comprising such a compound and the use of such a compound and composition in medicine.
