Fz7-21 (Ac-LPSDDLEFWCHVMY-NH2) TFA , a peptide antagonist of Frizzled 7 (FZD 7) receptors, specificly binds to FZD7 CRD subclass. The EC50 values are 58 and 34 nM for human and mouse FZD7 CRD, respectively. Fz7-21 impairs Wnt/β-catenin signaling in HEK293 cells stimulated with exogenous WNT3A (IC50=100 nM) or transfected with a construct expressing WNT3A or WNT1. Fz7-21 also blocks WNT3A-mediated stabilization of β-catenin in mouse L cells (IC50=50 nM). References: [1]. Nile AH, et al.
