Pexmetinib

Pexmetinib is a potent Tie-2 and p38 MAPK dual inhibitor, with IC₅₀s of 1 nM, 35 nM and 26 nM for Tie-2, p38α and p38β, respectively, and can be used in the research of acute myeloid leukemia. IC50 & Target: IC50: 1 nM (Tie-2), 35 nM (p38α), 26 nM (p38β)^[1] In Vitro: 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^[1].
