Pexmetinib is a potent and orally bioavailable dual p38 MAPK/Tie-2 inhibitor preventing tumor growth. | [Biological Activity]
pexmetinib (arry-614) is a potent inhibitor of cytokine synthesis, via the dual inhibition of p38 mitogen-activated protein kinase (mapk), and tie2/tek receptor tyrosine kinase. the in vitro ic50 values of arr y-614 for both tie2 and p38 mitogen-activated protein kinase are 1000 ng/ml and 100 ng/ml, respectively [1, 2].p38 is a group of mitogen-activated protein kinases. mapks are activated by the dual phosphorylation of tyr and thr residues in the thr-xaa-tyr motif in subdomain viii. data indicated that p38 mapk may mediate signaling to the nucleus [3].arry-614 is active against mapk and tie2/tek receptor tyrosine kinase in cells. in primary human bone marrow stromal cells, arry-614 inhibited basal cytokines with an ic50 value ranging from 50-100 nm [4].in dose escalation or expansion cohorts, treatment with arry-614 either once daily or twice daily was applied to forty-five patients. arry-614 reduced the levels of circulating biomarkers and the p38 mapk activation of bone marrow [1]. in ex vivo stimulated human whole blood, lps-induced cytokines was inhibited by arry-614 with an ic50 value ranging from 50-120 nm. arry-614 inhibited the release of il-6 from sea- or lps-challenged mice with an ed50 value less than 10 mg/kg. combining arry-614 with lenalidomide inhibited both pro-inflammatory cytokines and tumor growth in vivo with higher potency, compared with either agent alone [4]. | [storage]
