摘要

Compounds of formula (I) are inhibitors of p38 MAP kinase, and are therefore of utility in the treatment of, inter alia, inflammatory conditions including rheumatoid arthritis and COPD: formula (I) wherein: G is -N= or -CH=; D is an optionally substituted divalent mono- or bi-cyclic aryl or heteroaryl radical having 5 - 13 ring members; R6 is hydrogen or optionally substituted C1-C3 alkyl; P represents hydrogen and U represents a radical of formula (IA); or U represents hydrogen and P represents a radical of formula -A-(CH2)z-X1-L1 -Y-NH-CHR1R2 wherein A represents an optionally substituted divalent mono- or bicyclic carbocyclic or heterocyclic radical having 5 - 13 ring members; z, Y, L1, and X1 are as defined in the specification; R1 is a carboxylic acid group (-COOH), or an ester group which is hydrolysable by one or more intracellular esterase enzymes to a carboxylic acid group; and R2 is the side chain of a natural or non-natural alpha amino acid.
