(alphaR)-6-[5-chloro-2-[(tetrahydro-2H-pyran-4-yl)amino]-4-pyrimidinyl]-N-[(1S)-1-(3-fluoro-5-methoxyphenyl)-2-hydroxyethyl]-1,3-dihydro-alpha-methyl-1-oxo-2H-isoindole-2-acetamide
ERK 1/2 Inhibitor ASTX029 is an orally bioavailable inhibitor of the extracellular signal-regulated kinases (ERK) 1 and 2, with potential antineoplastic activity. Upon administration, ASTX029 specifically binds to and inhibits both ERK 1 and 2, thereby preventing the activation of mitogen-activated protein kinase (MAPK)/ERK-mediated signal transduction pathways. This results in the inhibition of ERK-dependent tumor cell proliferation and survival. The MAPK/ERK pathway is often upregulated in a variety of tumor cell types and plays a key role in the proliferation, differentiation and survival of tumor cells.
