Pexmetinib
Based on 2 publication(s) in Google Scholar
Pexmetinib (ARRY-614) is an orally active dual Tie-2 and p38 MAPK inhibitor. Pexmetinib binds to Tie-2 and p38 MAPK in a "DFG-out" conformation, attenuates the phosphorylation of p38, inhibits STAT3 activation, reduces the promoter-binding activity of NFATc1, and decreases the expression of MMPs. Pexmetinib inhibits leukemia cell proliferation, abrogates TNF-α-mediated myelosuppression of healthy hematopoietic stem cells, stimulates hematopoiesis in primary myelodysplastic syndrome (MDS) samples, inhibits RANKL-induced osteoclast formation and bone resorption, and suppresses migration, invasion and induced osteolysis of breast cancer cells. Pexmetinib can be used in research related to myelodysplastic syndrome, acute myeloid leukemia and breast cancer-induced osteolysis.
