Compounds are described of the formula
wherein:
R¹ is C₃₋₆alkyl or C₁₋₃alkylthioC₁₋₃alkyl;
R² is an optionally substituted C₁₋₆alkyl or C₁₋₆alkoxy group, aryl, heteroaryl, arylC₁₋₄alkyl, heteroarylC₁₋₄alkyl or a side-chain of a natural α-amino acid;
R³ is hydrogen, C₁₋₆alkyl, CHR⁴COR⁵ (where R⁴ is a side-chain of a natural α-amino acid and R⁵ is hydroxyl, C₁₋₆alkoxy or NHR⁶ where R⁶ represents a hydrogen atom or a C₁₋₆alkyl group) or a group (CH₂)nX (where n is 1 to 6 and X is hydroxyl, C₁₋₄alkoxy, heteroaryl or a group NR⁷R⁸ where R⁷ and R⁸ are each hydrogen or C₁₋₆alkyl or the group NR⁷R⁸ forms a 5 to 7 membered cyclic amine); and
Het is an optionally substituted cyclic imide where the cyclic imide ring system has the formula (i), (ii) or (iii)
in which A, B, C and D are each CH or 1 or 2 of A, B, C and D represents N and the others represent CH, and E and F may each independently represent CH or N; and physiologically acceptable salts and solvates thereof.
These compounds inhibit metalloproteases involved in tissue degradation. Compounds of the invention may be formulated for use in a variety of conditions involving tissue degradation including arthropathy, dermatological conditions, bone resorption, inflammatory diseases, tumour invasion and multiple sclerosis and related diseases involving myelin degradation, and in the promotion of wound healing.
