Nrf2 degrader 30 is a small molecule PROTAC that inhibits the degradation of Nrf2, thereby enhancing its activity. Nrf2 is a key transcription factor that regulates cellular antioxidant responses and various protective mechanisms. The activity of Nrf2 is primarily regulated by its interaction with Keap1, which serves as an E3 ubiquitin ligase complex adapter to promote Nrf2 ubiquitination and proteasomal degradation。
