represents aryl, heteroaryl or a group R
3
-L
2
-Ar
1
-L
3
-;
R
2
represents hydrogen or lower alkyl;
R
3
represents aryl or heteroaryl; and
Ar
1
represents an optionally substituted saturated, partially saturated or fully unsaturated 8 to 10 membered bicyclic ring system containing at least one heteroatom selected from O, S or N;
Y is carboxy or an acid bioisostere;
and their corresponding N-oxides or prodrugs, and pharmaceutically acceptable salts and solvates of such compounds and their corresponding N-oxides or prodrugs.
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).
该发明涉及一般式(I)的生理活性化合物:
其中:
R1代表芳基、杂环芳基或R3-L2-Ar1-L3-基团;
R2代表氢或较低的烷基;
R3代表芳基或杂环芳基;以及
Ar1代表含有至少一个来自O、S或N的杂原子的可选择取代的饱和、部分饱和或完全不饱和的8至10个成员的双环环系统;
Y为羧基或酸生物同位素;
以及它们对应的N-氧化物或前药,以及这些化合物及其对应的N-氧化物或前药的药用可接受盐和溶剂。
