Executive Summary

NRF2-targeted therapies represent a compelling opportunity in neurodegeneration drug development, with approximately 40-50 active trials examining NRF2-activating compounds. The field has seen significant pharmaceutical investment following successful clinical trials in chronic kidney disease (bardoxolone methyl) and COPD. Key investment themes include:

• Direct NRF2 activators (bardoxolone methyl, sulforaphane derivatives)
• Indirect NRF2 modulators (KEAP1 inhibitors, PKC activators)
• Natural product derivatives (isothiocyanates, polyphenols)
• Gene therapy approaches targeting NRF2 pathway components

Therapeutic Approaches

1. Direct NRF2 Activators

Directly bind to KEAP1 or NRF2 to release transcriptional activation:

| Approach | Advantages | Challenges |
|----------|------------|------------|
| KEAP1-binding electrophiles | Potent activation | Off-target effects |
| NRF2-binding disruptors | Targeted approach | Limited CNS penetration |
| Protein-protein interaction inhibitors | Novel mechanism | Drug discovery challenges |

2. Indirect NRF2 Modulators

Activate NRF2 through upstream signaling pathways:

| Target | Compound Class | Examples |
|--------|---------------|----------|
| PKC | Phorbol esters, bryostatin | Limited due to toxicity |
| MAPK | MEK inhibitors | Selumetinib in trials |
| PI3K/Akt | [mTOR](/mechanisms/mtor-signaling-pathway-pathway) inhibitors | Rapamycin, everolimus |
| AMPK | Biguanides, AICAR | Metformin trials in PD |

3. Natural Product-Derived

Plant-derived compounds with NRF2-activating properties:

• Sulforaphane: Broccoli extract, most studied
• Curcumin: Turmeric derivative, bioavailability challenges
• Resveratrol: SIRT1 activator, also NRF2 effects
• EGCG: Green tea catechin, multiple
