Target	ERK1 ERK2
In Vitro	KO-947 is a 10 nM inhibitor of ERK with at least 50-fold selectivity against a panel of 450 kinases. KO-947 blocks ERK signaling and proliferation of tumor cells exhibiting dysregulation of MAPK pathway signaling, including mutations in BRAF, NRAS or KRAS, at low nanomolar concentrations[1].
In Vivo	In cell-line derived xenograft studies, KO-947 profoundly suppresses ERK signaling for up to five days after a single dose and induces regressions in RAS- and RAF-mutant melanoma, NSCLC and pancreatic cancer models on administration schedules ranging from daily to weekly. Intermittent dosing enables comparable antitumor activity at reduced dose-intensity[1].
