Glutathione peroxidases (GPx) are a family of enzymes with the ability to reduce organic and inorganic hydroperoxides to the corresponding alcohols using glutathione or thioredoxin as an electron donor. These enzymes promote hydrogen peroxide metabolism and protect cell membrane structure and function from oxidative damage. Dysregulated GPx expression is connected with severe pathologies, including obesity and diabetes. GPx1 has been reported to be involved in both pro- and anticancer effects in different tumor models.

In mammals, the GPxs family consists of eight members (GPx1-GPx8) identified so far; five of them (GPx1-GPx4 and GPx6) contain selenocysteine in the catalytic center and the other three are cysteine-containing proteins. GPx1 is one of the most critical members of the GPxs family that catalytically reduces hydrogen peroxide to produce water. The function of GPx3 is to scavenge H2O2 and lipoperoxides in the plasma to reduce systematic oxidative stress and to maintain the bioavailability of vascular nitric oxide. Gpx4 is an essential mammalian glutathione peroxidase, which protects cells against detrimental lipid peroxidation and governs a novel form of regulated necrotic cell death, called ferroptosis.

    GPX4-IN-13
    		Inhibitor
    GPX4-IN-13 (compound 16) is a GPX4 inhibitor with anticancer activity. GPX4-IN-13 reduces thyroid cell proliferation and induces ferroptosis by inhibiting the expression level of GPX4. GPX4-IN-13 inhibits the growth of three thyroid cancer cell lines: N-thy-ori-3-1 (IC50=8.39 μM), MDA-T32 (IC50=10.28 μM) and MDA-T41 (IC50=8.18 μM).

    Lubiprostone-d7
    		Inhibitor
    Lubiprostone-d7 (RU-0211-d7) is the deuterium labeled Lubiprostone. Lubiprostone (SPI-0211) increases intestinal fluid secretion through generation of CIC-2/CFTR and activation of cAMP signaling pathway. Lubiprostone inhibits myeloperoxidase (MPO) activity, downregulates Indomethacin (HY-14397)-induced iNOS and TNFα expression. Lubiprostone can be used for chronic constipation research.

    Ludartin
    		Inhibitor
    Ludartin a sesquiterpene lactone, which can be isolated from the plant Artemisia carruthii Wood. Ludartin reduces the expression of myeloperoxidase and malondialdehyde, enhances the expression of glutathione and superoxide dismutase in spinal cord tissue. Ludartin inhibits neuronal apoptosis. Ludartin inhibits the upregulation of tumor necrosis factor-α, interleukin-1β, and interleukin-6. Ludartin improves the motor function of rats with spinal cord injury.

    2-Acetamidophenol (Standard)
    		Activator
    2-Acetamidophenol (Standard) is the analytical standard of 2-Acetamidophenol. This product is intended for research and analytical applications. 2-Acetamidophenol (Orthocetamol) is a regulator that targets ferroptosis and glutathione metabolic pathways, is the ortho-regioisomer of Paracetamol (HY-66005). 2-Acetamidophenol has anti-atherosclerotic activity, and inhibiting total cholesterol (TC) and triglyceride (TG) in a zebrafish hyperlipidemia model with IC50s for 30 μM and 40 μM, respectively. 2-Acetamidophenol upregulates the expression of glutathione synthesis-related genes (such as GCLC, GCLM, GSS) and iron ion transport genes (such as FPN1, FTH), reduces the accumulation of intracellular reactive oxygen species (ROS) and ferrous ions (Fe2+), and enhances the activity of glutathione peroxidase GPX4, thereby inhibiting macrophage phagocytosis of oxidized low-density lipoprotein (ox-LDL) and foam cell formation.
