GtoPdb Ligand ID: 9974

Synonyms: MK8353 | SCH900353
PDB Ligand
Compound class: Synthetic organic
Comment: MK-8353 (formerly know as SCH900353) is an orally bioavailable dual mechanism ERK1/2 inhibitor, i.e. it inhibits ERK1/2 catalytic activity and phosphorylation of ERK1/2 [1]. It has improved pharmacokinetic properties in comparison to SCH772984 (a preclinical ERK1/2 inhibtor tool compound) and has shown preliminary anti-tumour efficacy in patients with BRAF or RAS mutated metastatic melanoma and colorectal cancers.
(Note: ERK1= MAPK3, ERK2= MAPK1).

Bioactivity Comments
MK-8353 demonstrates selectivity for ERK1/2 over 227 tested human kinase enzymes [1]. Only CDC like kinase 2 (CLK2), fms related tyrosine kinase 4 (FLT4), and Aurora kinase B were inhibited by >50% by 1 μM MK-8353. The in vitro anti-proliferative activity of MK-8353 against BRAFV600-mutant and RAS-mutant cancer cell lines is documented in Supplemental Table 1, and in vivo antitumour activity vs. a panel of human xenograft models, including the BRAFV600 mutant colon cancer (Colo-205) and the BRAFV600 mutant melanoma (SK-MEL-28) models [1].
