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.
公式(I)的化合物是p38 MAP激酶的抑制剂,因此在治疗炎症性疾病包括类风湿性关节炎和COPD方面具有效用:公式(I)其中:G是-N =或-CH =; D是具有5-13个环成员的可选取代的二价单环或双环芳基或杂芳基基团; R6是氢或可选取代的C1-C3烷基; P代表氢,U代表公式(IA)的基团;或U代表氢,P代表公式-A-(CH2)z-X1-L1-Y-NH-CHR1R2的基团,其中A代表具有5-13个环成员的可选取代的二价单环或双环碳环或杂环基团; z,Y,L1和X1如规范中定义; R1是羧酸基(-COOH)或可由一个或多个细胞内酯酶酶水解为羧酸基的酯基;而R2是天然或非天然α氨基酸的侧链。
