SCH772984

Biological Activity

SCH772984 is a novel and selective inhibitor of ERK1/2 that displays behaviors of both type I and type II kinase inhibitors. SCH772984 has nanomolar cellular potency in tumor cells with mutations in BRAF, NRAS, or KRAS. SCH772984 effectively inhibited MAPK signaling and cell proliferation in BRAF or MEK inhibitor-resistant models as well as in tumor cells resistant to concurrent treatment with BRAF and MEK inhibitors. SCH772984 induces tumor regressions in xenograft models at tolerated doses.

	Method	QRT-PCR
	Cell Lines	Primary cortical neurons
	Concentrations	5 nM, 50 nM
	Incubation Time	4 h
	Results	These results suggested that in addition to the increase in GluN2A protein levels in the synaptosomes and mitochondria, additional unknown mechanism(s), which could up-regulate the ERK-CREB signaling, might also contribute to the resistance of Hipk2-/- DA neurons to CCCP.

Protocol (for reference only)

Cell Experiment
Cell lines	BRAF- or RAS-mutant tumor cells
Preparation method	Cell proliferation experiments were carried out in a 96-well format (six replicates), and cells were plated at a density of 4,000 cells per well. At 24 hours after cell seeding, cells were treated with DMSO or a 9-point IC50 dilution (0.001–10 μmol/L) at a final concentration of 1% DMSO for all concentrations. Viability was assayed 5 days after dosing using the ViaLight luminescence kit (Lonza) following the manufacturer's recommendations (n = 6, mean ± SE). For the cell line panel viability assay, cells were treated with SCH772984 for 4 days and assayed by the CellTiterGlo luminescent cell viability assay (Promega).
Concentrations	0.001–10 μmol/L
Incubation time	4 days

Animal Experiment
Animal models	Female nude mice bearing human LOX BRAF-mutant/MiaPaCa KRAS-mutant pancreatic/ melanoma xenograft model
