Keap1-Nrf2 is the major regulator of cytoprotective responses to electrophilic chemicals or reactive oxygen species (ROS). Keap1 is an E3 ligase, which induces the degradation of Nrf2 by ubiquitin-proteasome system (UPS). Upregulation of Nrf2 inducing by inactivation of Keap1 is often observed in cancer cells. Aberrant activation of Nrf2 in cancer cells accelerates proliferation and metabolism. For this case, Nrf2 is an attractive molecule as a therapeutic target in cancer and a lot number of Nrf2 inhibitors are developed. What’s interesting, Nrf2 induction is also reported to be treatment strategies for accelerating the detoxification of carcinogens and protect the body from chemical carcinogenesis.

    Necrosulfonamide-d4
    		Activator 99.65%
    Necrosulfonamide-d4 is the deuterium labeled Necrosulfonamide (HY-100573). Necrosulfonamide is a MLKL and Gasdermin D (GSDMD) inhibitor, capable of separately inhibiting necroptosis and pyroptosis of cells. Necrosulfonamide does not affect the activation of upstream signals, but specifically inhibits the downstream executor oligomerization step. Necrosulfonamide reduces the expression of the key kinases NLRP3 and caspase-1 involved in necroptosis and pyroptosis, activate the Nrf2 pathway and the downstream antioxidant enzymes, and also downregulates a variety of inflammatory factors. Necrosulfonamide plays significant roles in various diseases such as neurodegenerative diseases (such as Parkinson’s disease), tissue damage and ischemia-reperfusion injury, inflammatory bowel disease, osteoarthritis and fracture repair, and hair loss by regulating two important programmed necrosis pathways.
