Background:

NRX-2663 is an enhancer of the interaction between β-catenin, and its cognate E3 ligase, SCFβ-TrCP. NRX-2663 enhances the binding of β-catenin peptide for β-TrCP with an EC50 of 22.9 µM and a Kd of 54.8 nM[1].

NRX-2663 displays both improved potency in the binding assay with pSer33/Ser37 β-catenin (EC50 of 80 µM) and cooperativity of binding (13-fold). NRX-2663 also markedly enhances the ubiquitylation of the pSer33/Ser37 β-catenin peptide, with ubiquitin chain formation at ligand concentrations of 16 μM and above resembling ubiquitin chain formation on wild-type pSer33/pSer37 β-catenin peptide[1].
