How to use

In Vitro:

VPC-14337 (0-500 nM) inhibits proliferation of MCF-7 (luminal), MDA-MB-231 (claudin-low), MDA-MB-468 (basal-like) and SkBr3 (HER2-OE) cells in a dose-dependent manner, with IC50 value of 1170±105.0 nM against MDA-MB-231 cell line. VPC-14337 significantly inhibits self-renewal and proliferation of BCSCs, and suppresses BCSC population with a distinct phenotype. VPC-14337 significantly decreases average expression levels of FZD1, FZD10, WNT1, WNT7B, CTNNB1, MYC, and LRP5 at transcriptional level. Moreover, VPC-14337 also efficiently down-regulates the expression of other stemness genes including ALDH1, CD44 and ABCG2. VPC-14337 blocks colon cancer cell growth in vitro in a dose-dependent manner with great differences in the inhibitory concentration (IC50), ranging from 0.6 to 65 μM for colon cancer cells with mutations in WNT signaling. VPC-14337 decreases messenger RNA (mRNA) and protein levels of known WNT target genes as c-MYC and thereby led to the induction of p21. VPC-14337 ultimately inhibits Wnt signalling despite its lack of efficacy on CK1. VPC-14337 imposes specific toxicity on cardiac fibroblasts in ischemia (IC50=9.5 nM). The cytotoxic effect of VPC-14337 on cardiac fibroblasts specifically under glucose- and glutamine-deficient condition.

In Vivo:

In the xenograft model, VPC-14337 (500 nM)-pretreatment strongly delays tumor size and tumor weight, and the tumor volume is markedly decreased.
