Mechanism of Action

Features	Does not directly inhibit MEK1, MEK2, BRAF, or CRAF enzyme activity.
Targets/IC₅₀/Ki	ERK2 ^[1] (Cell-free assay) 1 nM ERK1 ^[1] (Cell-free assay) 4 nM
In vitro	SCH772984 is a novel, selective and ATP competitive inhibitor of ERK1/2. This compound inhibits phosphorylation of the ERK substrate p90 ribosomal S6 kinase (T359/S363 phospho-RSK) in a dose-dependent manner. It also inhibits phosphorylation of residues in the activation loop of ERK itself. This inhibitor demonstrates EC50 values <500 nM in approximately 88% and 49% of BRAF-mutant or RAS-mutant tumor lines, respectively. Importantly, it effectively inhibited MAPK signaling and cell proliferation in tumor cells resistant to concurrent treatment with BRAF and MEK inhibitors. ^[1]
Kinase Assay	ERK2 IMAP enzymatic assay
Kinase Assay	SCH772984 is tested in 8 point dilution curves in duplicate against purified ERK2 or ERK1. The enzyme is added to the reaction plate. and incubated with this compound before adding a solution of substrate peptide and ATP. 14μl of diluted enzyme (0.3ng active ERK2 per reaction) is added to each well of a 384-well plate. The plates are gently shaken to mix the reagents and incubated for 45 minutes at room temperature. The reaction is stopped with 60μl of IMAP Binding Solution (1:2200 dilutions of IMAP beads in 1X Binding Buffer). The plates are incubated at room temperature for an additional 0.5 hours to allow complete binding of phosphopeptides to the IMAP beads. Plates are read on the LJL Analyst.
In vivo	SCH772984 induces tumor regressions in xenograft models at tolerated doses. This compound effectively inhibites MAPK signaling and cell proliferation in BRAF or MEK inhibitor resistant models. ^[1]
