The present invention provides a novel thiol derivative [I] which has an excellent matrix metalloprotease inhibiting activity and is useful as a pharmaceutical composition, particularly a therapeutic agent or prophylactic agent for osteoarthritis and rheumatoid arthritis and a salt thereof, the thiol derivative being a compound represented by the formula [I]:
wherein ring A represents an optionally substituted aromatic heterocyclic ring;
ring B represents an optionally substituted homocyclic or heterocyclic ring;
R1 represents a hydrogen atom, an optionally substituted hydrocarbon group, an acyl group, an optionally substituted heterocyclic group or SR2 (wherein R2 represents a hydrogen atom, an optionally substituted hydrocarbon group, an acyl group or an optionally substituted heterocyclic group);
X represents an optionally substituted divalent C1-3 aliphatic hydrocarbon group;
Y represents an optionally substituted hydrocarbon group, a halogen atom, a carboxy group, an acyl group, an optionally substituted hydroxy group, an optionally substituted amino group, SR3 (wherein R3 represents a hydrogen atom, an optionally substituted hydrocarbon group, an acyl group or an optionally substituted heterocyclic group), an oxo group, a thioxo group, an optionally substituted imino group, a nitro group or a cyano group; and
q represents an integer of 0 to 5.
