XMD17-109

XMD17-109 is a cell-permeable, non-cytotoxic ATP site-targeting pyrimido-diazepinone derivative that acts as a potent inhibitor against ERK5 (MAPK7, BMK1) kinase activity in cell-free assay, and EGF-induced ERK5 autophosphorylation in HeLa cells.

XMD17-109 is a cell-permeable, non-cytotoxic ATP site-targeting pyrimido-diazepinone derivative that acts as potent inhibitor against ERK5 (MAPK7, BMK1) kinase activity in cell-free assay (IC₅₀ = 162 nM; [ATP] = 50 μM) and EGF-induced ERK5 autophosphorylation in HeLa cells (IC₅₀  = 90 nM). XMD17-109 displayed excellent target selectivity on a 442-kinase panel. XMD17-109 effectively inhibits inflammatory stimuli-induced IL-6 and IL-8 production from human endothelial cells in vitro and protects mice from LPS-induced mortality and systemic inflammation & coagulopathy in vivo with good pharmacokinetics.
