Product Description
Information
KYA1797K KYA1797K is a highly potent and selective Wnt/β-catenin inhibitor with IC50 of 0.75 µM (TOPflash assay). In vitro
KYA1797K significantly decreases reporter activities for the Wnt/β-catenin and MAPK/ERK pathways but does not affect the reporter activities of other cancer-related pathways, such as the Notch and TGFβ pathways, thus, KYA1797K selectively regulates the Wnt/β-catenin and Ras/ERK pathways. KYA1797K enhances the β-catenin binding affinity of endogenous axin, GSK3β and β-TrCP. Interaction between APC and β-catenin is not enhanced by KYA1797K. It promotes the formation of the β-catenin destruction complex. KYA1797K degrades both β-catenin and Ras in these cells(CRC lines SW480, LoVo, DLD1 and HCT15) in a dose-dependent manner, cell proliferation is also suppressed by KYA1797K treatment. KYA1797K inhibits proliferation of CRC cells mainly via destabilization of β-catenin with additional Ras degradation. KYA1797K directly targeted axin and modulated conformation of the β-catenin destruction complex.
In vivo
KYA1797K administration by intraperitoneally injection(i.p.) (25 mg/kg) reduces both weight and volume of the tumor by 70% in mice carrying xenografted tumors from the D-MT cell line that harbors both APC and KRAS mutations. KYA1797K treatment significantly reduces levels of β-catenin and Ras proteins as well as Wnt/β-catenin and Ras signaling target. No change in the weight and no abnormalities in liver tissues of mice treated with KYA1797K. KYA1797K significantly reduces the subcellular localization of β-catenin in the nuclei and pan-Ras on the membrane of tumor cells. Thus, KYA1797K has anti-tumor effect. Cell Data
