Keap1-Nrf2

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.

    Rosolutamide
    Activator
    Rosolutamide (ASC-JM17), a curcumin analog, is an orally active, potent Nrf1 and Nrf2 activator. Rosolutamide activates Nrf1, Nrf2 and heat shock factor 1 (Hsf1), thereby activating the expression of proteasome subunits, antioxidant enzymes and molecular chaperones. Rosolutamide degrades the polyglutamine (polyQ) androgen receptor (AR) via the ubiquitin-proteasome pathway and improves motor function in mouse models of spinal and bulbar muscular atrophy (SBMA). Rosolutamide improves mitochondrial function and promotes autophagy, decreases mutant protein aggregates, and attenuates intracellular/mitochondrial reactive oxygen species (ROS) levels.

    L-Cystine (Standard)
    Activator
    L-Cystine (Standard) is the analytical standard of L-Cystine. This product is intended for research and analytical applications. L-Cystine, the extracellular form of L-Cysteine (HY-Y0337), is a nutritionally dispensable semiessential sulfur-containing amino acid, occurring in proteins of plants and animals. L-Cystine induces Nrf2 protein elevation in a Keap1 (HY-P75897)-dependent manner and activates Nrf2 transcription factor. L-cystine can elicit cytoprotection by reducing ROS generation and protecting against oxidant- or doxorubicin-induced apoptosis. The reduced reabsorption of L-Cystine in renal tubules and its poor solubility in urine are the important causes of cystine precipitation and cystine crystal formation eventually leading to kidney stones. L-Cystine combined with L-theanine (HY-15121) enhances the production of antigen-specific IgG by increasing glutathione (GSH) levels and T helper 2 (Th2) mediated responses in mice. L-Cystine is promising for research of cystinuria and cystinosis
