Pexmetinib

Research use only, not for human use.

Pexmetinib (ARRY-614) is a potent, orally active, dual Tie-2/p38 MAPK inhibitor with IC50 of 1, 26 and 35 nM for Tie-2, p38α and p38β, respectively.

Pexmetinib (ARRY-614) is a potent, orally active, dual Tie-2/p38 MAPK inhibitor with IC50 of 1, 26 and 35 nM for Tie-2, p38α and p38β, respectively; demonstrates in vitro mechanistic models (Angpt-1 or anisomycin-stimulated HUVEC) as well as functional readouts (LPS-induced TNF-alpha release from human PBMCs) with IC50 of 2282 nM and 172 nM for Tie2 and p38, respectively; abrogates cytokine mediated myelosuppresive effects in hematopoietic cells; inhibits leukemic cell proliferation and stimulates hematopoietic activity in MDS; inhibits LPS-induced TNF-alpha release) murine models .Blood Cancer Phase 1 Discontinued.

Pexmetinib is a Tie-2 and p38 MAPK dual inhibitor, with IC50s of 1 nM, 35 nM and 26 nM for Tie-2, p38α and p38β, respectively. Pexmetinib also shows IC50s of 4 nM (Abl), 10 nM (Arg), 28 nM (FGFR1), 47 nM (Flt1), 42 nM (Flt4), 41 nM (Fyn), 26 nM (Hck), 25 nM (Lyn), and 26 nM (MINK), respectively. Pexmetinib (0.5, 1 μM) blocks leukemic cell proliferation and stimulates hematopoietic activity in myelodysplastic syndromes.
