State-of-the-Art Nrf2 Inhibitors: Therapeutic Opportunities in Non-Cancer Diseases

Area of Science:

• Biochemistry
• Molecular Biology
• Cell Biology

Background:

• Nuclear factor erythroid 2-related factor (Nrf2) is a transcription factor crucial for cellular defense against oxidative stress.
• While Nrf2 activation aids in developing therapeutics, its oncogenic role in cancer cell proliferation highlights its complex functions.
• Impaired autophagy can shift Nrf2 from a protective to a detrimental state, leading to ferroptosis.

Purpose of the Study:

• To review diseases where Nrf2 inhibition may offer therapeutic benefits.
• To summarize recent medicinal chemistry approaches for developing Nrf2 inhibitors.
• To emphasize the need for further research into Nrf2's role in chronic diseases.

Main Methods:

• Literature review of studies on Nrf2's role in various diseases.
• Analysis of recent medicinal chemistry strategies for Nrf2 inhibitor development.
• Discussion of conflicting results and methodological variations in Nrf2 research.

Main Results:

• Nrf2's dual role as both protective and detrimental depending on cellular context.
• Potential therapeutic benefits of Nrf2 inhibition in specific non-cancer diseases.
• Challenges in Nrf2 research due to varied experimental models and inhibition/activation strategies.

Conclusions:

• Nrf2 inhibition shows promise for treating certain diseases, especially chronic conditions.
• Targeting transcription factors like Nrf2 requires sophisticated medicinal chemistry approaches.
• Further investigation is crucial to fully understand and leverage Nrf2's complex role in disease pathogenesis.
