Biological target:
KYA1797K is a potent and selective Wnt/β-catenin inhibitor with an IC50 of 0.75 µM.
In vitro activity:
In cultured proximal tubular cells, KYA1797K shows a better effect on inhibiting cellular senescence and could better suppress mitochondrial dysfunction and ameliorate the fibrotic changes, at the same dose as that in ICG-001. Reference: Kidney Dis (Basel). 2022 Sep 27;8(5):408-423. https://pubmed.ncbi.nlm.nih.gov/36466073/
In vivo activity:
Furthermore, KYA1797K effectively inhibited Kras-driven tumorigenesis in the KrasLA2 mouse model by suppressing the Ras-ERK pathway. Reference: Sci Rep. 2019 Jan 24;9(1):648. https://pubmed.ncbi.nlm.nih.gov/30679620/
