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].
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].
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].
