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.

| Sulforaphane
Sulforaphane is an orally active inducer of the Keap1/Nrf2/ARE pathway. Sulforaphane promotes the transcription of tumor-suppressing proteins and effectively inhibits the activity of HDACs. Sulforaphane (SFN) extracted from broccoli sprout is an agent with potent anti-oxidant and anti-inflammatory activity. |
| Ginsenoside-Rh3
Ginsenoside Rh3 is a bacterial metabolite of Ginsenoside Rg5. Ginsenoside Rh3 induces Nrf2 activation in human retinal cells. |
| Astilbin
Astilbin is a flavonoid that enhances NRF2 activation. Astilbin also inhibited TNF-α expression and NF-κB activation. |
| Luteolin
Luteolin (Luteolol) is a natural flavonoid that is a modulator of Nrf2. Luteolin exhibits dual regulation of Nrf2. In tumour cells, low concentrations of Luteolin activate the Nrf2 signalling pathway and promote Nrf2 nuclear translocation, while high concentrations of Luteolin inhibit Nrf2 activity and negatively modulate the Nrf2/ARE signalling pathway. Luteolin is also a PDE inhibitor. In addition, Luteolin has a variety of biological activities, including antioxidant, anti-inflammatory, anticancer, and neuroprotection. Luteolin can be used in studies related to ferroptosis. |
| ML 334
ML334 (LH601A) is a inhibitor of Keap1- Nrf2 interaction. |
