Fz7-21 (Ac-LPSDDLEFWCHVMY-NH2) TFA is a potent peptide antagonist of FZD7 receptors , selectively binds to FZD7 CRD subclass and alters the conformation of the CRD and the architecture of its lipid-binding groove. The EC50 values are 58 and 34 nM for human and mouse FZD7 CRD, respectively. Fz7-21 TFA impairs the function of FZD7 in Wnt-β-catenin signalling and stem cell function in intestinal organoids[1][2].
Fz7-21 (Ac-LPSDDLEFWCHVMY-NH2) TFA (0-100 μM; 6 h; HEK293-TB cells) impairs Wnt signaling with IC50 value of 100 nM[1].
Fz7-21 (Ac-LPSDDLEFWCHVMY-NH2) TFA (1 µM) blocks WNT3A-mediated stabilization of β-catenin in mouse L cells with IC50 value of 50 nM[1].
Fz7-21 (Ac-LPSDDLEFWCHVMY-NH2) TFA (200 µM; 48 h; LGR5–GFP+ stem cells) disrupts LGR5+ stem cell function[1].
