Biological Activity

Description iCRT14 is a β-catenin/Tcf inhibitor with a Ki value of 54 ± 5.2 μM in homogeneous fluorescence polarization (FP) assay.
Targets
β-catenin/Tcf [1]
54 μM(Ki)
In vitro
In vitro

iCRT14 suppresses the transcriptional activity of canonical Wnt signaling, downregulates Wnt/β-catenin-induced target genes, and inhibits the growth of colorectal cancer cells in vitro[1]. iCRT14 shows a modest reduction in the amount of Dvl but has no effect on Dvl phosphorylation itself. iCRT14 inhibits the Wnt responsive STF16-luc reporter in mammalian HEK293 cells with an IC50 of 40.3 nM. iCRT14 can also interfere with TCF binding to DNA in addition to its ability to influence TCF-β-catenin interaction[2].
Cell Research Cell lines Rat2 cells
Concentrations 25 and 50 μM
Incubation Time 2 h
Method

Rat2 cells are pretreated with iCRTs at the indicated doses and stimulated for 2 h with Wnt3a or Wnt5a. Cell lysate is harvested for western analysis of Dvl2 phosphorylation.

Administration of iCRT14 to the HCT116 and HT29 xenograft models reveals a marked decrease in CycD1, coincided with reduced proliferation of the tumors. Furthermore, these effects are correlated with a marked reduction (∼50%) in the initial growth rate of tumors within the first 3 wk (∼day 19) of compound administration. After day 19, however, the rate of tumor growth is comparable with that of DMSO-treated control. Throughout the course of the study, the mice does not display any signs of systemic toxicity or weight loss that would indicate off-target or nonspecific effects. The compound may be metabolized rapidly in vivo, thus reducing its bioavailability[2].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
