Compounds of the following formula have pharmaceutical properties: <CHEM> in which X is R min (HO)C=C(CN)-, R<1>(CO)-CH(CN)- or <CHEM> R<1> and R<2> are each hydrogen or C1-6 alkyl, R<3>, R<4>, R<5> and R<6> are each hydrogen, hydroxy, halogen, nitro, cyano, carboxy, C1-4 alkyl, C1-4 alkoxy, C1-4 alkylthio, halo-substituted C1-4 alkyl, halo-substituted C1-4 alkoxy, halo substituted C1-4 alkythio, C2-5 alkoxycarbonyl, optionally substituted phenyl, optionally substituted phenoxy, R min R sec N- where R min and R sec are each hydrogen or C1-4 alkyl or R'''CONH- where R''' is C1-4 alkyl, or a group of the formula -CR<7>R<8>R<9> in which R<7>,R<8> and R<9> are each C1-6 alkyl, halo-substituted C1-6 alkyl or optionally substituted phenyl, or R<7> and R<8>, together with the carbon atom to which they are attached, form a cycloalkyl group containing 3 to 7 carbon atoms, or R<7>, R<8> and R<9> together with the carbon atom to which they are attached, form a bicycloalkyl group containing 4 to 9 carbon atoms, and Y is a 5- or 6-membered heterocyclic ring excluding pyrazole; and salts thereof. |
