Abstract:
Enamine derivatives of formula (1) are described. In said formula , R a group Ar L Ar Alk- in which Ar is an aromatic or heteroaromatic group, L is a covalent bond or a linker atom or group, Ar is an arylene or heteroarylene group and Alk is a chain -CH2-CH(R)-, -CH=C(R)- or (a) in which R is a carboxylic acid or a derivative or biostere thereof; R is a hydrogen atom or a C1-6alkyl group; Cy is a cycloaliphatic or heterocycloaliphatic ring in which X is a N atom or a C(R ) group; R is a oxo, thioxo, or imino group; R and R are each a hydrogen atom or optional substituent; provided that Cy is not a cyclobutenedione group; and the salts, solvates, hydrates and N-oxides thereof. The compounds are able to inhibit the binding of integrins to their ligands and are of use in the prophylaxis and treatment of immune or inflammatory disorders, or disorders involving the inappropriate growth or migration of cells.
Abstract:
The present invention provides an albumin-binding compound essentially of the following elements: a spacer group, a water-soluble bridging group, a fatty acid chain and an acidic group characterised in that the acidic group is attached to the distal end of the fatty acid chain. The invention also provides an albumin-binding compound to which one or more biologically active moieties are attached.
Abstract:
Branched molecular scaffolds are provided which are capable of linking two polymer residues (derived, for example, from polyethylene glycol) to two, three or four residues derived from biologically active molecules (e.g. from whole antibodies or from functionally active fragments or derivatives thereof), the latter being attached to the scaffold by means of hydrolytically stable linkages.

Abstract:
The present invention provides a compound consisting essentially of the following elements : one or more reactive groups ; and two or more cross- linked antibodies or fragments thereof ; characterised in that the or each reactive group is suitable for attaching an effector molecule but does not react with any of the antibodies or fragments thereof.
