<p>The invention is directed to physiologically active compounds of formula (I) wherein R1 represents R?3-Z3, R3-L2-R4-Z3-, R3-L3-Ar1-L4-Z3- or R3-L3-Ar1-L2-R4-Z3-; R2¿ represents hydrogen, halogen, lower alkyl or lower alkoxy; A1 represents a straight chain C¿2-3?alkylene linkage optionally substituted by one or more groups chosen from alkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, imino, oxo, thioxo, or alkyl substituted by -ZR?6, -NY1Y2, -CO¿2R6 or -C(=O)-NY1Y2; L1 represents a direct bond; an alkenylene, alkylene, alkynylene, cycloalkenylene, cycloalkylene, heteroaryldiyl, heterocycloalkylene or arylene linkage each optionally substituted by (a) an acidic functional group, cyano, oxo, -S(O)¿mR?9, R3, -C(=O)-R3, -C(=O)-OR?3, -N(R8¿)-C(=O)-R?9, -N(R8¿)-C(=O)-OR?9, -N(R8)-SO¿2-R?9, -NY4Y5¿ or -[C(=O)-N(R?10)-C(R5)(R11)]¿p-C(=O)-NY4Y5, or by (b) alkyl substituted by an acidic functional group, or by S(O)¿mR?9, -C(=O)-NY?4Y5 or -NY4Y5¿; a -[C(=O)-N(R?10)-C(R5)(R11)]¿p-linkage; a-Z2-R12-linkage; a -C(=O)-CH¿2?-C(=O)-linkage; a -R?12-Z2-R12¿- linkage; a -C(R4)(R13)-[C(=O)-N(R?10)-C(R5)(R11)]¿p- linkage; or a -L5-L6-L7- linkage; Z?1 is NR17¿ or O; Y is carboxy or an acid bioisostere; and the corresponding N-oxides, and their prodrugs; and pharmaceutically acceptable salts and solvates of such compounds and their N-oxides and 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 (α4β1).</p> |
