Research use only, not for human use.

Losmapimod (GSK-AHAB, GW856553X, SB856553)?is a selective, potent, orally active p38 MAPK inhibitor with pKi of 8.1 and 7.6 for p38α and p38β, respectively.

Losmapimod (GSK-AHAB, GW856553X, SB856553)?is a selective, potent, orally active p38 MAPK inhibitor with pKi of 8.1 and 7.6 for p38α and p38β, respectively; displays no significant activity for p38γ, p38δ (<25% inhibition at 10 uM), and COX-2; significantly and dose-dependently improves survival, endothelial-dependent and -independent vascular relaxation in rat model of cardiovascular disease.Ischemia Phase 3 Clinical(In Vitro):In the spontaneously hypertensive stroke-prone rat (SHR-SP), chronic treatment with GSK-AHAB significantly and dose-dependently improves survival, endothelial-dependent and -independent vascular relaxation, and indices of renal function, and it attenuates dyslipidemia, hypertension, cardiac remodeling, plasma renin activity (PRA), aldosterone, and interleukin-1β (IL-1β).
