Biological Activity

Description

ETC-159 (ETC-1922159) is an orally available, potent porcupine inhibitor with an IC50 of 2.9 nM for inhibiting β-catenin reporter activity in STF3A cells.

Targets

Porcn ^[1]

In vitro
In vitro	ETC-159 treatment causes decreased abundance of Wnt3a-stabilized β-catenin protein in both mouse L cells and HEK293 cells. ETC-159 inhibits β-catenin signaling in response to multiple active Wnts. ETC-159 inhibits mouse PORCN with an IC50 of 18.1 nM, whereas the IC50 for Xenopus Porcn is approximately fourfold higher (70 nM)^[1].
Cell Research	Cell lines	Mouse L cells
	Concentrations	100 nM
	Incubation Time	0-24 h
	Method	Mouse L cells stably expressing Wnt3a are trypsinizised and treated with DMSO or 100 nM ETC-159 before plating in cell culture dishes. The cells are harvested at indicated time points and total β-catenin levels are assessed by immunoblot.

In Vivo
In vivo	ETC-159 is orally bioavailable and effectively inhibits the growth of mouse mammary tumor virus-Wnt1 tumors. After a single oral dose of 5 mg/kg in mice, ETC-159 is rapidly absorbed into the blood with a Tmax of ~0.5 h and oral bioavailability of 100%. The plasma half-life is ~1.18 h and its concentration in the blood remained above the in vitro IC50 for at least 16 h. Treatment of mice with increasing doses of ETC-159 leads to a dose-related increase in exposure. ETC-159 also effectively inhibits Wnt autocrine signaling and growth of teratocarcinomas. ETC-159 effectively inhibits the growth and induces differentiation of colon cancers with RSPO translocations and induces global remodeling of gene expression. Suppression of Wnt/β-catenin signaling with ETC-159 in genetically defined tumors induces irreversible cellular differentiation thus preventing regrowth of these tumors^[1].
Animal Research	Animal Models	BALB/c nude, NCr nude or NOD-scid-gamma mice
	Dosages	5, 30 or 100 mg/kg
	Administration	by oral gavage
