The invention is directed to physiologically active compounds of formula (I):
1
wherein:
R
1
represents optionally substituted aryl, optionally substituted heteroaryl, R
3
NH—Ar
1
—L
2
— or R
3
—NH—C(═O)—NH—Ar
2
—L
2
—; R
3
represents aryl or heteroaryl; Ar
1
represents a saturated, partially saturated or fully unsaturated 8- to 10-membered bicyclic ring systerm containing at least one heteroatom selected from O, S or N; Ar
2
represents aryldiye or heteroaryldiyl; L
1
represents a linkage, such as an alkylene linkage; L
2
represents an alkylene chain linkage; R
2
represents hydrogen, halogen, C
1-4
alkyl or C
1-4
alkoxy; and Y is carboxy or an acid bioisostere;
but excluding compounds where an oxygen, nitrogen or sulfur atom is attached directly to a carbon carbon multiple bond of an alkenylene or alkynylene residue;
and the corresponding N-oxides and ester prodrugs thereof, and the pharmaceutically acceptable salts and solvates of such compounds, and the N-oxides and ester prodrugs thereof.
Such compounds have valuable pharmaceutical properties, in particular the ability to regulate the interaction of VCAM-1 and fibronectin with the integrin VLA-4 (&agr;4&bgr;1).
本发明涉及式(I)的生理活性化合物:1其中:R1表示可选取代的芳基,可选取代的杂芳基,R3NH—Ar1—L2—或R3—NH—C(═O)—NH—Ar2—L2—;R3表示芳基或杂芳基;Ar1表示含有至少一个从O、S或N中选取的杂原子的饱和、部分饱和或完全不饱和的8至10个成员的双环状环系;Ar2表示芳基双亚基或杂芳基双亚基;L1表示连接,例如烷基连接;L2表示烷基链连接;R2表示氢、卤素、C1-4烷基或C1-4烷氧基;Y是羧基或酸生物异构体;但不包括氧、氮或硫原子直接连接到烯烃或炔烃残基的碳碳多键的化合物;以及其相应的N-氧化物和酯前药、该化合物的药学上可接受的盐和溶剂化物,以及其N-氧化物和酯前药。这些化合物具有有价值的药物性质,特别是调节VCAM-1和纤维连接蛋白与整合素VLA-4(&agr;4&bgr;1)相互作用的能力。
