Dihydro-benzo(1,4)oxazines

Abstract

The invention is directed to physiologically active compounds of formula (I): wherein R1 represents R3—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 C2-3alkylene linkage optionally substituted by one or more groups chosen from alkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, imino, oxo, thioxo, or alkyl substituted by —ZR6, —NY1Y2, —CO2R6 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)mR9, R3, —C(═O)—R3, —C(═O)—OR3, —N(R8)—C(═O)—R9, —N(R8)—C(═O)—OR9, —N(R8)—SO2—R9, —NY4Y5 or —[C(═O)—N(R10)—C(R5)(R11)]p—C(═O)—NY4Y5, or by (b) alkyl substituted by an acidic functional group, or by S(O)mR9, —C(═O)—NY4Y5 or —NY4Y5; a —[C(═O)—N(R10)—C(R5)(R11)]p— linkage; a —Z2—R12— linkage; a —C(═O)—CH2—C(═O)— linkage; a —R 12—Z2—R12— linkage; a —C(R4)(R13)—[C(═O)—N(R10)—C(R5)(R11)]p— linkage; or a —L5—L6—L7— linkage; Z1 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).
