A p38α MAP kinase inhibitor
IC50: 13 nM
BMS-582949 is a p38 MAPK inhibitor
p38R MAP kinase plays a key role in regulating the biosynthesis of various inflammatory cytokines, such as tumor necrosis factor alpha and interleukin-1β. Thus, p38R inhibitors are considered as a promising therapy for inflammatory disease treatment.
In vitro: BMS-582949 was found to be 450-fold selective over Jnk2, a MAP kinase involved in inflammation, and 190-fold selective against Raf. Moreover, the binding mode of BMS-582949 with p38R was further demonstrated by X-ray crystallographic analyses [1].
In vivo: In a pseudoestablished rat adjuvant arthritis model, BMS-582949 at doses of 10 and 100 mg/kg was found to display dose-dependent reduction in paw swelling with qd dosing. In addition, with bid dosing at doses of 1 and 5 mg/kg, BMS-582949 showed improved efficacy, resulting in great reduction in paw swelling. Moreover, the statistically significant reduction in paw swelling was also observed with the treatment of BMS-582949 at doses as low as 0.3 mg/kg bid [1].
Clinical trial: A multicenter FDG-PET trial showed that in stable atherosclerosis, 12 weeks of treatment with BMS-582949 was not able to reduce arterial inflammation or hs-CRP when compared with placebo, while intensification of statin therapy could decrease arterial inflammation significantly [2].
