Biological Activity
MRK-A is a highly potent, selective, orally bioavailable inhibitor of YAP1/TEAD with EC50 of 3.4 nM in cellular MCF7 assay expressing TEAD-reporter luciferase, inhibits TEAD palmitoylation that leads to allosteric YAP1/TEAD complex disruption.
MRK-A exhibits potent cell growth inhibition in the Hippo pathway-deficient NCI-H226 and MSTO-211H vs proficient NCI-H28 and NCI-2452 CTG assays.
MRK-A suppressed the transcription of endogenous YAP1/TEAD target genes in H226 cells
MRK-A (30 mg/kg BID) demonstrated dose-dependent efficacy in the NCI-H226 (mesothelioma) xenograft model, showed suppression of TEAD target genes ANKRD1 and CTGF in a dose-dependent manner over 24 h in NF2-deficient NCI-H226 (mesothelioma) tumor-bearing mice.
