Biological Activity

Description Pexmetinib is a potent, orally bioavailable, dual p38 MAPK/Tie-2 inhibitor with IC50 of 4 nM/18 nM in a HEK-293 cell line. Phase 1.
Targets
p38 MAPK [1] Tie-2 [1]
In vitro In HeLa cells, Pexmetinib inhibits phospho-HSP27 with IC50 of 2 nM. In isolated PBMCs and human whole blood cells, Pexmetinib inhibits LPS-Induced TNFα with IC50 of 4.5 nM and 313 nM, respectively. [1]
In vivo In male Swiss Webster mice, Pexmetinib (30 mg/kg, p.o.) inhibits the production of the proinfl ammatory cytokines TNFα and IL6 in response to lipopolysaccharide (LPS) or staphyloccus enterotoxin A. In established RPMI 8226 xenografts, ARRY-614 (25 mg/kg, p.o.) inhibits tumor growth and shows additive activity when combines with thalidomide. In ovarian carcinoma A2780 xenografts, ARRY-614 (30 mg/kg, p.o.) also shows additive tumor growth inhibition activity when combines with Taxol. [1]
