intestinal organoids

Fz7-21 ((Ac)-LPSDDLEFWCHVMY-NH2) is a peptide antagonist of FZD7 . It antagonises WNT3A-induced Wnt-β-catenin signalling in HEK293 expressing FZD7. 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).

GA-017 is a potent, selective inhibitor of LATS1 and LATS2 (large tumor suppressor kinase 1/2), exhibiting IC50 values of 4.10 and 3.92 nM, respectively. This compound simultaneously acts as an activator of cell proliferation by promoting YAP/TAZ activation and their nuclear translocation. Additionally, GA-017 enhances cell growth in 3D culture conditions and augments the ex vivo formation of mouse intestinal organoids [1].

RS-246204 is an R-spondin-1 substitute compound capable of initiating and sustaining intestinal organoids in R-spondin-1-deficient media, activating R-spondin-dependent pathways in DSS-induced colitis models, and promoting regeneration of damaged intestinal epithelium.
