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).

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the CDK toolkit. All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

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].
