p38 MAP kinase is a ubiquitous, highly conserved enzyme which regulates the production of proinflammatory mediators (such as TNFα and IL-1) in response to inflammatory cytokines or environmental stress [6,12-13]. Four p38 MAP kinase homologs have been identified, as have the upstream and downstream signalling mechanisms and enzyme substrates [5,8,15]. Inhibition of these enzymes reduces inflammatory cytokine synthesis. p38 MAP kinase enzymes are therefore highly pursued drug targets for conditions including inflammation, arthritis and other joint diseases, septic shock, and myocardial injury.
