How to use

In Vitro:

Talmapimod (SCIO-469) hydrochloride (100-200 nM; 1 hour) inhibits phosphorylation of p38 MAPK in MM cells. 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.

In Vivo:

Talmapimod hydrochloride (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.
