Propanoic acid derivatives of formula (1) are described: Ar-X1-Ar1-Z-R in which Ar is a nitrogen base containing group; X1 is linker atom or group; Ar1 is an optionally substituted 5- or 6-membered nitrogen-containing aromatic or non-aromatic monocycle; Z is a group -CH(R13)CH2- [in which R13 is an optionally substituted aliphatic, cycloaliphatic, heteroaliphatic, heterocycloaliphatic, aromatic or heteroaromatic group], -C(R?12a)(R13)-CH(R12b¿)- [in which R?12a and R12b¿ together with the carbon atoms to which they are attached form a C¿3-7?cycloalkyl group] or C(R?13¿)=CH-; R is a carboxylic acid (-CO¿2?H) or a derivative or biostere thereof; and the salts, solvates, hydrates and N-oxides thereof. The compounds are able to inhibit the binding of αV integrins to their ligands and are of use in the prophylaxis and treatment of immune or inflammatory disorders.
