Talmapimod (hydrochloride)

Talmapimod (SCIO-469) hydrochloride is an orally active and selective inhibitor of p38α MAPK with an IC50 of 9 nM. Talmapimod hydrochloride inhibits the secretion of inflammatory factors (such as TNFα, IL-1β, IL-6, and VEGF) by suppressing the p38α MAPK pathway, and it also inhibits angiogenesis and osteoclast activation. Talmapimod hydrochloride inhibits the growth of multiple myeloma cells and induces apoptosis. Talmapimod hydrochloride can be used to study various hematological malignancies (such as multiple myeloma, myelodysplastic syndrome) [1][2][3][4].
