摘要

Compounds of general formula (I) wherein R<1> represents a hydrogen atom or a C1-C6 alkyl, C1-C6 alkenyl, phenyl, phenyl(C1-C6)alkyl, C1-C6 alkylthiomethyl, phenylthiomethyl, substituted phenylthiomethyl, phenyl(C1-C6)alkylthiomethyl or heterocyclylthiomethyl group; or R<1> represents -S-R wherein R represents a group alpha ; R<2> represents a hydrogen atom or a C1-C6 alkyl, C1-C6 alkenyl, phenyl(C1-C6)alkyl, cycloalkyl(C1-C6)alkyl, or cycloalkenyl(C1-C6)alkyl; R<3> represents an amino acid side chain or a C1-C6 alkyl, benzyl, (C1-C6)alkoxybenzyl, benzyloxy(C1-C6)alkyl or benzyloxybenzyl group; R<4> represents a hydrogen atom or a methyl group; R<5> represents a group (CH2)nA; or R<4> and R<5> together represent a group beta ; Q represents CH2 or CO; m is an integer from 1 to 3; n is an integer from 1 to 6; and A represents a hydroxy, (C1-C6)alkoxy, (C2-C7)acyloxy, (C1-C6)alkylthio, phenylthio, (C2-C7)acylamino or N-pyrrolidone group or a salt and/or N-oxide and/or (where the compound is a thio-compound) a sulphoxide or sulphone thereof have collagenase inhibition activity and are useful in the management of disease involving tissue degradation and/or the promotion of wound healing. Diseases involving tissue degradation include arthropathy (particularly rheumatoid arthritis), inflammation, dermatological diseases, bone resorption diseases and tumour invasion.
