Description_x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ K67 is a specific inhibitor against the interaction between KEAP1 (Kelch-like ECH-associated protein 1) DC (double glycine repeat and C-terminal region) domain and S349-phosphorylated (human Ser349, mouse Ser351) KIR (Keap1-interacting region) of p62/SQSTM1, thereby preventing phospho-p62 from blocking KEAP1-DC and NRF2 (nuclear factor erythroid 2-related factor 2) DLGex motif association. K67 effectively inhibits the proliferation of HCC (hepatocellular carcinoma) cultures (by 59% of Huh7 cells post 72 h 50 μM K67 treatment) with high cellular p62 S351-phosphorylation by restoring KEAP1-driven NRF2 ubiquitination and degradation.
