The invention relates to compounds of the general formula (I) <CHEM> and physiologically acceptable salts, hydrates and bioprecursors thereof, in which R1 and R2, which may be the same of different, each represent hydrogen, C1-10 alkyl, cycloalkyl, alkenyl, alkynyl, aralkyl, trifluoroalkyl, or alkyl substituted by hydroxy, alkoxy, amino, alkylamino dialkylamino or cycloalkyl or R1 and R2 may together with the nitrogen atom to which they are attached form a 5 to 10 membered ring which may be saturated or may contain at least one double bond, may be unsubstituted or may be substituted by one or more C1-3 alkyl groups or a hydroxy group and/or may contain another heteroatom which is oxygen or sulphur; Alk represents a straight or branched alkylene chain of 1 to 6 carbon atoms, Q represents a furan or thiophene ring in which incorporation into the rest of the molecule is through bonds at the 2- and 5- positions, the furan ring optionally bearing a further substituent R6 adjacent to the group R1R2N-Alk, or Q represents a benzene ring in which incorporation into the rest of the |
