    • The invention is directed to physiologically active compounds of general formula (I): wherein R1 is lower alkyl, R2 is aryl, arylalkyl, heteroaryl or heteroarylalkyl, or R1 and R2 together with the nitrogen atom to which they are attached form a cyclic amine, Ar1 is aryldiyl or heteroaryldiyl, Ar2 is optionally substituted phenylene or heteroaryldiyl, L1 is an a —R5—R6— linkage where R5 is alkylene, alkenylene or alkynylene and R6 is a direct bond, cycloalkylene, heterocycloalkylene, arylene, heteroaryldiyl, —C(═Z1)—NR4—, —NR4—C(═Z1)—, —Z1—, —C(═O)—, —C(═NOR4)—, —NR4—, —NR4—C(═Z1)—NR4—, —SO2—NR4—, —NR4—SO2—, —O—C(═O)—, —C(═O)—O—, —NR4—C(═O)—O— or —O—C(═O)—NR4—, L2 is a direct bond, an optionally substituted alkylene, alkenylene, alkynylene, cycloalkenylene, cycloalkylene, heteroaryldiyl, heterocycloalkylene or aryldiyl linkage, a —[C(═O)—N(R9)—C(R4)(R10)]p— linkage, a —Z3—R11— linkage, a —C(═O)—CH2—C(═O)— linkage or a —R11—Z3—R11— linkage, and Y is carboxy or an acid bioisostere; and the corresponding N-oxides, and their prodrugs; and pharmaceutically acceptable salts and solvates (e.g. hydrates) 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 (&agr;4&bgr;1).
