| Losmapimod (GW856553X) Usage And Synthesis |
| Description | GW 856553X is a dual inhibitor of p38α and p38β MAPK (Kis = 0.0079 and 0.025 μM, respectively, in cell-free assays). It is selective for p38α and p38β MAPK over p38γ and p38δ MAPK when used at a concentration of 10 μM. GW 856553X inhibits LPS-induced TNF-α production in isolated rat and human peripheral blood mononuclear cells (PBMCs; IC50s = 0.6 and 0.13 μM, respectively). It decreases disease severity in a mouse model of collagen-induced arthritis when administered at doses ranging from 0.8 to 20 mg/kg. GW 856553X (1.2 and 12 mg/kg) improves survival, normalizes blood pressure, and reduces increases in plasma levels of HDL, LDL, and triglycerides in spontaneously hypertensive stroke-prone rats fed a high-salt high-fat diet. | | Uses | Losmapimod is a selective, potent, and orally active p38 MAPK inhibitor. | | references | [1]. willette rn, eybye me, olzinski ar, et al. differential effects of p38 mitogen-activated protein kinase and cyclooxygenase 2 inhibitors in a model of cardiovascular disease. j pharmacol exp ther, 2009, 330(3): 964-970.
