MedChemExpress - Model Talmapimod - 309913-83-5

Talmapimod (SCIO-469) is an orally active, selective, and ATP-competitive p38α inhibitor with an IC50 of 9 nM. Talmapimod shows about 10-fold selectivity over p38β, and at least 2000-fold selectivity over a panel of 20 other kinases, including other MAPKs[1][2][3].

Description：Talmapimod (SCIO-469) is an orally active, selective, and ATP-competitive p38α inhibitor with an IC50 of 9 nM. Talmapimod shows about 10-fold selectivity over p38β, and at least 2000-fold selectivity over a panel of 20 other kinases, including other MAPKs.

In Vitro：Talmapimod (SCIO-469) (100-200 nM; 1 hour) inhibits phosphorylation of p38 MAPK in MM cells[1]. Talmapimod inhibits LPS-induced TNF-a production in human whole blood[2]. Talmapimod decreases constitutive p38alpha MAPK phosphorylation of both 5T2MM and 5T33MM cells[3].

In Vivo：Targeting p38α MAPK with Talmapimod (SCIO-469) decreases myeloma burden in addition to preventing the development of myeloma bone disease[2]. Talmapimod inhibits multiple myeloma growth and prevents bone disease in the 5T2MM and 5T33MM models[3]. Talmapimod (10-90 mg/kg; p.o.; twice daily orally for 14 days) dose-dependently reduced tumor growth and also dose-dependently reduced weight of the palpable tumors at termination[4].

IC50 & Target：p38α 9 nM (IC50) p38β 90 nM (IC50)
