Abstract
p38 mitogen-activated protein kinases (p38 MAPKs) are key signalling molecules that regulate cellular behavior in response to environmental stresses. They regulate pro-inflammatory cytokines and therefore p38 MAPKs are implicated in the pathogenesis of many inflammatory-driven conditions, including atherosclerosis. Therapeutic inhibition of p38 MAPKs to attenuate inflammation has been the focus of comprehensive research in the last 2 decades, following the discovery of p38α as the molecular target of pyrindinyl imidazole compounds, which suppress the cytokines tumor necrosis factor-α and interleukin-1. The potential of p38 MAPK inhibitors was initially explored within archetypal inflammatory conditions such as rheumatoid arthritis and Crohn’s disease, but early studies demonstrated poor clinical efficacy and unacceptable side effects. Subsequent clinical trials evaluating different p38 MAPK inhibitor compounds in disease models such as chronic obstructive pulmonary disease (COPD) and atherosclerosis have shown potential clinical efficacy. This review aims to provide succinct background information regarding the p38 MAPK signaling pathway, a focus of p38 MAPKs in disease, and a brief summary of relevant pre-clinical studies. An update of human clinical trial experience encompassing a clinically orientated approach, dedicated to cardiovascular disease follows. It provides a current perspective of the therapeutic potential of p38 MAPK inhibitors in the cardiovascular domain, including safety, tolerability, and pharmacokinetics.
