glutathione peroxidase

Glutathione Peroxidase (GSH-Px; EC 1.11.1.9), a member of the peroxidase family, catalyzes the oxidation of reduced glutathione (GSH) to oxidized glutathione (GSSG) by forming a disulfide bridge, while concurrently reducing hydrogen peroxide or lipid peroxides to water, serving as a potent antioxidant and protecting against oxidative stress [1].

5-Aminosalicylic Acid (5-ASA) is a specific PPARγ agonist and also inhibits P21-activated kinase 1(PAK1) and NF-Κb. 5-Aminosalicylic Acid has anti-cancer and anti-inflammatory activities. 5-Aminosalicylic acid can inhibit the activity of osteopontin (OPN).

RSL3 (RSL3 1S) is an inhibitor of GPX4, and inhibits system xc- that blocks GSH synthesis (IC50=100 nM). RSL3 is a VDAC-independent activator of ferroptosis that is selective for tumor cells carrying oncogenic RAS.

ML162 is a covalent glutathione peroxidase 4 (GPX4) inhibitor that induces ferroptosis. ML162 has antitumor activity and selectively inhibits cell lines expressing mutant RAS oncogenes.

AZD8309 is a potent, orally available antagonist of the chemokine receptor CXCR2 that regulates neutrophil transport, significantly reduces MPO in the pancreas and lung, and decreases trypsin and elastase activity in the pancreas.AZD8309 can be used to study a range of inflammatory diseases.

MPO-IN-1 is an orally active myeloperoxidase (MPO) inhibitor, inhibiting MPO and thyroid peroxidase (TPO). It is useful in inflammation research.

icFSP1 is a mitochondria-associated apoptosis-inducing factor regulator with antitumor activity for the study and treatment of tumor diseases.

Cefdinir (FK-482) is a third-generation, semi-synthetic cephalosporin antibiotic effective against common bacterial infections of the ear, sinus, throat, and skin.

Nabumetone (BRL14777)(BRL14777) is a non-steroidal anti-inflammatory drug and its active metabolite 6MNA inhibits the enzymes cyclo-oxygenase I and II.

Melatonin (Melatonine) is a natural hormone secreted by the pineal gland that activates melatonin receptors. Melatonin is a hormone that regulates the biological clock and also has antioxidant and anti-inflammatory activities.

4-POBN (Myeloperoxidase Inhibitor 1) is a potent and irreversible inhibitor of myeloperoxidase (IC50 = 0.3 µM). 4-POBN can be used in studies about subacute stroke.

4-Methylesculetin (Methylesculetin) is one of the coumarin derivatives with great anti-oxidant and anti-inflammatory activities.

Sodium 2-mercaptoethanesulfonate (Uromitexan) is a sulfhydryl compound used to prevent urothelial toxicity by inactivating metabolites from antineoplastic agents, such as ifosfamide or cyclophosphamide.

Pipecolic acid (2-Piperidinecarboxylic acid), a metabolite of lysine found in human physiological fluids such as urine, plasma and CSF, is an important regulator of immunity in plants and humans alike.

3-Chloro-L-Tyrosine (Chlorotyrosine), a specific marker of myeloperoxidase-catalyzed oxidation, is markedly elevated in low-density lipoprotein isolated from human atherosclerotic intima. In particular, myeloperoxidase halogenates tyrosine residues in plasma proteins and generates 3-chlorotyrosine (CY). The detection of free chlorotyrosine in blood or urine arises from the degradation of these chlorinated proteins. CY concentrations may be useful for monitoring the activation of neutrophils in asthmatic patients.

GSTO1-IN-1 is a potent glutathione S-transferase omega 1 inhibitor (GSTO1) with an IC50 of 31 nM.

PF-06282999, a potent and selective myeloperoxidase inhibitor, is potentially useful for the treatment of cardiovascular diseases.

NBDHEX is a potent inhibitor of glutathione S-transferase P1-1 (GSTP1-1) .

4-Aminosalicylic acid (para-aminosalicylic acid) is an analog of para-aminobenzoic acid (PABA) with antitubercular activity.

AZD5904 is a potent and irreversible human Myeloperoxidase (MPO) inhibitor(IC50 of 140 nM and has similar potency in mouse and rat).

ZX782 acts as a GPX4 protein degrader and an inducer of ferroptosis (Ferroptosis), targeting GPX4 for destruction via both the ubiquitin-proteasome system and the autophagy-lysosome pathway. Following the degradation of GPX4 induced by ZX782, there is a significant increase in the accumulation of lipid reactive oxygen species (ROS) in HT1080 cells.

Ferroptosis-IN-17 (Compound 18) is an inhibitor of ferroptosis with an EC50 value of 0.57 μM. It effectively reduces the accumulation of intracellular ferrous ions and lipid peroxidation while restoring levels of glutathione (GSH) and glutathione peroxidase 4 (GPX4). In rat plasma, Ferroptosis-IN-17 demonstrates good solubility and notable metabolic stability. This compound holds potential for research in tumor suppression, neurodegenerative diseases, and cardiovascular disorders.

GPX4-IN-9 (Compound A16) is an inhibitor of glutathione peroxidase 4 (GPX4) that specifically targets GPX4, both in vitro and in vivo, to induce ferroptosis. It exhibits cytotoxic effects on pancreatic cancer cells and can be utilized for cancer research.

Ezatiostat hydrochloride (TLK199 HCl) is an effective inhibitor of glutathione S-transferase. Ezatiostat hydrochloride is a novel glutathione analog and the potential treatment of cytopenias. In addition, Ezatiostat hydrochloride has been revealed to selectively bind to and thus inhibit GSTP1-1.
