1H-Imidazole-4-carboxamide, N-[(1S)-2-amino-1-(3-chloro-5-fluorophenyl)ethyl]-1-[5-methyl-2-[(tetrahydro-2H-pyran-4-yl)amino]-4-pyrimidinyl]-, compd. with benzenesulfonate (1:1)

Biological Activity

ERK-IN-3 benzenesulfonate is a potent and orally active inhibitor of ERK. ERK-IN-3 benzenesulfonate inhibits ERK1/2 with low single-digit nM IC50 values. ERK-IN-3 benzenesulfonate can be used for the research of cancers driven by RAS mutations[1]. ERK-IN-3 inhibits the phosphorylation of ERK1/2 substrates such as RSK1, FRA1, and Elk1 in various cell lines[1].ERK-IN-3 showes single-digit nanomolar antiproliferative activity that is selective for MAPK-pathway dependent cancer cell lines[1]. ERK-IN-3 (daily p.o.) inhibits tumor growth in multiple BRAF and KRAS mutant xenograft models in mice and was well tolerated at efficacious doses[1].
