Compounds are disclosed of the formula (I):
in which U, T, V and W are each a nitrogen atom or carbon atom. When U, T, V or W is a carbon atom, it may be substituted. The compounds are inhibitors of p38 MAP kinase and are useful for treating inflammatory diseases such as arthritis. An example of such a compound is:
The invention provides a compound for use in the prophylaxis or treatment of a disease state or condition mediated by a p38 MAP kinase such as rheumatoid arthritis and osteoarthritis; the compound being of the general formula (I): wherein U, T, V and W are each a nitrogen atom or a group CR4 provided that no more than three of U, T, V and W are nitrogen atoms; R0 is hydrogen, C1-4 hydrocarbyl, halogen or a group -A-R3; R1 is hydrogen, C1-4 hydrocarbyl or a group -A-R3; provided that only one of R0 and R1 is a group -A-R3; R2 is hydrogen, C1-4 hydrocarbyl or halogen; A is a carbon- or heteroatom-containing linker group having a linking chain length of one or two atoms; R3 is a monocyclic or bicyclic heteroaryl group containing from five to twelve ring members; each group R4 is independently selected from hydrogen, hydroxy, halogen, nitro, cyano, a monocyclic heterocyclic group having up to seven ring members, a group N(R5)2, a group C(O)N(R6)2, a group S02N(R6)2, a group Ra-Rb and a group Y; provided that no more than one group Y is present;

2-amino-3-benzyloxypyridine 1 (IC(50) 1.3 mM) and 3-(2-(4-pyridyl)ethyl)indole 2 (IC(50) 35 microM) identified using X-ray crystallographic screening of p38alpha MAP kinase. Using two separate case studies, the article focuses on the key compounds synthesized, the structure-activity relationships and the binding mode observations made during this optimization process, resulting in two potent lead series that demonstrate
