| 产品描述: | p38 MAPK 抑制剂;p38 MAPK Inhibitors;产品介绍:Pexmetinib (ARRY-614)是一种有效的,口服生物可利用的,双重p38 MAPK/Tie-2抑制剂,其在HEK-293细胞中的IC50分别为4 nM/18 nM。Phase 1。;InformationPexmetinib (ARRY-614) Pexmetinib (ARRY-614) 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.Targetsp38 MAPK ; Tie-2In vitroIn 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.In vivoIn 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. |
