Synonyms: compound 23 [PMID: 31730343] | MS-432
Compound class: Synthetic organic
Comment: MS432 is the first-reported mitogen-activated protein kinase kinase 1/2 (MEK1/2) degrader . Structurally MS432 is a hybrid molecule, combining a kinase-targeting ligand (based on mirdametinib) with a VHL-engaging moeity In this case VHL ligand 2, (S,R,S)-AHPC-Me . These types of agents are known as PROTACs, or proteolysis targeting chimeras. It targets the kinases for VHL E3 ligase- and proteasome-mediated degradation. In vitro, the effect of MS432 is phenocopied by MEK1/2 knockdown. MS432 is bioavailable and suitable for in vivo studies.
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.✖
