KYA1797K is a potent and selective Wnt/β-catenin inhibitor with an IC50 of 0.75 uM.
KYA1797K binds directly to the regulators of G-protein signaling domain of axin, initiating b-catenin and Ras degradation through enhancement of the b-catenin destruction complex activating GSK3b. KYA1797K effectively suppresses the growth of CRCs harboring APC and KRAS mutations. KYA1797K enhances formation of the β-catenin destruction complex and induced GSK3β activation, leading to phosphorylation of both β-catenin and K-Ras at S33/S37/T41 and T144/T148. KYA1797K degrades both β-catenin and Ras SW480, LoVo, DLD1 and HCT15 cells in a dose-dependent manner. KYA1797K destabilizes β-catenin and Ras in DLD1 cells expressing WT β-catenin or WT K-Ras[1].
KYA1797K significantly suppresses tumor growth and progression both in mouse xenografts of CRC cells harboring APC and K-Ras mutations and in an Apcmin/+/KrasG12DLA2 mouse model. KYA1797K administration (25 mg/kg) reduces both weight and volume of the tumor by 70%. KYA1797K treatment significantly reduces levels of β-catenin and Ras proteins as well as Wnt/β-catenin and Ras signaling target [1].

Cell experiment: | SW480, LoVo, DLD1 and HCT15 cells are treated with KYA1797K (0.2, 1, 5, 25 µM) for 24 h or 4 d. MTT assay is used to determine effects of KYA1797K on cell proliferation[1]. |
Animal experiment: | Mice: KYA1797K (20 mg/kg) is injected intraperitoneally (i.p.) into mice carrying xenografted tumors from the D-MT cell line that harbors both APC and KRAS mutations for 28 days. Tumor weight is measured at time of sacrifice and tumor volumes of mice are measured every 4 d[1]. |
