KYA1797K is a potent and selective Wnt/β-catenin inhibitor with an IC₅₀ of 0.75 µM.

IC50: 0.75 (Wnt/β-catenin)^[1]

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 Apc^min/+/Kras^G12DLA2 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].
