Compounds of formula (I) are inhibitors of matrix metalloproteinases, and are of use in the treatment of, for example fibrotic disease, multiple sclerosis, emphysemia, bronchitis and asthma: formula (I) wherein Ar represents an optionally substituted aryl, heteroaryl, C3-C8 cycloalkyl or heterocycloakyl group; R represents hydrogen or C1-C6 alkyl, or C3-C6 cycloalkyl; Alk represents a divalent C1-C5 alkylene or C2-C5 alkenylene radical; and R1 and R2 taken together with the nitrogen atom to which they are attached form a first heterocycloalkyl ring which is optionally fused to a second C3-C8 cycloalkyl or heterocycloalkyl ring, the said first and second rings being optionally substituted by at least one group of formula (II): formula (II) wherein m, p and n are independently 0 or 1; Z represents, hydrogen, or an optionally substituted carbocyclic or heterocyclic ring of from 5 to 7 ring atoms which is optionally fused to another optionally substituted carbocyclic or heterocyclic ring of from 5 to 7 ring atoms; Alk1 and Alk2 independently represent optionally substituted divalent C1-C3 alkylene radicals; X represents -0-, -S-, -S(O)-, -S(O2)-, -C(=O)-, -NH-, -NR3-, -S(O2)NH-, -S(O2)NR3-, -NHS(O2)-, or -NR3S(O2)-, where R3 is C1-C3 alkyl.
式(I)的化合物是基质金属蛋白酶的抑制剂,并可用于治疗纤维化疾病、多发性硬化症、肺气肿、支气管炎和哮喘等疾病:式(I)中Ar代表可选择地取代的芳基、杂环芳基、C3-C8环烷基或杂环烷基基团;R代表氢或C1-C6烷基,或C3-C6环烷基;Alk代表二价的C1-C5烷基或C2-C5烯基基团;R1和R2与它们连接的氮原子一起形成第一杂环烷基环,该环可选择地与第二个C3-C8环烷基或杂环烷基环融合,所述的第一和第二环可选择地被至少一个式(II)的基团取代:式(II)中m、p和n独立地为0或1;Z代表氢,或由5至7个环原子组成的可选择地取代的碳环或杂环环,该环可选择地与另一个由5至7个环原子组成的可选择地取代的碳环或杂环环融合;Alk1和Alk2独立地代表可选择地取代的二价的C1-C3烷基基团;X代表-0-、-S-、-S(O)-、-S(O2)-、-C(=O)-、-NH-、-NR3-、-S(O2)NH-、-S(O2)NR3-、-NHS(O2)-或-NR3S(O2)-,其中R3为C1-C3烷基。
