KY-1220

Research use only, not for human use.

KY-1220 is a small molecule destabilizer of both β-catenin and Ras via inhibition of the Wnt/β-catenin pathway (IC50=2.1 uM).

KY-1220 is a small molecule destabilizer of both β-catenin and Ras via inhibition of the Wnt/β-catenin pathway (IC50=2.1 uM); dose-dependently decreases Wnt3a-CM-induced TOPflash reporter activation and mRNA expression of Wnt target genes CCND1 and MYC in HEK293 cells; reduces β-catenin and pan-Ras protein levels via polyubiquitin-dependent proteasomal degradation, consequently inhibits the activities of both ERK and Akt in various CRC cell lines; efficiently inhibits proliferation and transformation in HCT15, SW480, D-WT and D-MT CRC cells.

KY1220 shows an IC50 of 2.1 μM in HEK293 reporter cells. KY1220 dose dependently decreases Wnt3a-CM-induced TOPflash reporter activation and mRNA expression of Wnt target genes CCND1 and MYC in HEK293 cells. In HEK293 cells, both β-catenin and panRas protein levels are similarly reduced in a dose-dependent manner after treatment with KY1220, whereas the mRNA levels of CTNNB1 (which encodes β-catenin), NRAS, KRAS and HRAS remain unchanged. K-Ras, which has a critical role in progression of CRCs, is also destabilized by KY1220 via polyubiquitin-dependent proteasomal degradation. KY1220 accelerates the degradation rates of both β-catenin and Ras in SW480 cell lines. Ras destabilization by KY1220 consequently inhibits the activities of both ERK and Akt, which are downstream effectors of Ras in SW480 cells harboring a KRAS mutation. The proliferation and transformation of the HCT15, SW480, D-WT and D-MT CRC cells are efficiently inhibited after treatment with KY1220.
