Talmapimod hydrochloride is a selective and ATP-competitive p38α inhibitor (IC50: 9 nM). It also shows about 10-fold selectivity over p38β, and at least 2000-fold selectivity over a panel of 20 other kinases, including other MAPKs.

| Description | Talmapimod hydrochloride is a selective and ATP-competitive p38α inhibitor (IC50: 9 nM). It also shows about 10-fold selectivity over p38β, and at least 2000-fold selectivity over a panel of 20 other kinases, including other MAPKs. |
| Targets&IC50 | p38α:9 nM, p38β:90 nM |
| In vitro | Talmapimod hydrochloride inhibits LPS-induced TNF-a production in human whole blood. Talmapimod hydrochloride decreases constitutive p38alpha MAPK phosphorylation of both 5T2MM and 5T33MM cells. Talmapimod hydrochloride (100-200 nM; 1 hour) inhibits phosphorylation of p38 MAPK in MM cells [1][2][3]. |
| In vivo | Talmapimod hydrochloride (10-90 mg/kg; P.o.; twice daily for 14 days) dose-dependently reduced both tumor growth and the weight of palpable tumors at termination [4]. |
