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

Ezatiostat (TER199(free base)) is a tripeptide analog of glutathione that can selectively inhibit GSTP1-1 catalytic activity.

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

LAS17 is a selective and highly effective inhibitor of glutathione S-transferase Pi (GSTP1), which inhibits GSTP1 activity in vitro in a concentration-dependent manner. LAS17 has anti-tumor activity and inhibits breast cancer cell growth.

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

N-Acetyl lysyltyrosylcysteine amide is a non-toxic, potent, reversible, and specific myeloperoxidase (MPO) tripeptide inhibitor that effectively inhibits MPO production in vivo, attenuates neuronal damage, preserves brain tissue and neurological function post-stroke, and inhibits MPO-dependent hypochlorite (HOCl) production, protein nitration, and LDL oxidation. It is also used in the study of bronchial dysplasia.

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

PF-1355 (PF 06281355) is a selective 2-thiouracil mechanism-based MPO inhibitor. PF-1355 is used for treatment of vasculitic diseases.

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.

Tinoridine hydrochloride (Y-3642 hydrochloride) is a non-steroidal anti-inflammatory drug. Tinoridine hydrochloride (5-100 μM), produced a concentration-dependent inhibition on the simultaneous increases in lipid peroxide formation and renin release induced by 50 μM ascorbic acid in the renin granule fraction. On the other hand, indomethacin, hydrocortisone, and prednisolone, which had no ability to inhibit the lipid peroxidation in the renin granule fraction, did not influence the release of renin from the granules. These results suggest that tinoridine suppresses renin release by inhibiting the oxidative disintegration of membranes of renin granules.

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

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

MPO-IN-28 is a novel potent, irreversible Myeloperoxidase (MPO) inhibitor with IC50 of 44 nM.

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

GPX4-IN-4 (Compound 24) is a potent inhibitor of GPX4, employed in cancer research [1].

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.

NC-R17, an RSL3-based noncovalent GPX4 degrader implicated in ferroptosis, demonstrates anti-tumor activity and is utilized in the design of noncovalent GPX4-targeted proteolysis targeting chimeras (PROTACs) [1].

N-Acetyl lysyltyrosylcysteine amide acetate is an effective and selective tripeptide inhibitor of myeloperoxidase (MPO). N-Acetyl lysyltyrosylcysteine amide acetate inhibits MPO-dependent hypochlorous acid (HOCl) generation, protein nitration, and LDL ox

Moracin N, a ferroptosis inhibitor derived from mulberry leaves, exhibits neuroprotective activity by mitigating oxidative stress [1].

Lepadin E, a notably cytotoxic compound, effectively stimulates ferroptosis via the canonical p53-SLC7A11-GPX4 pathway. By elevating p53 and repressing SLC7A11 and GPX4 expression, it heightens ROS and lipid peroxidation while also augmenting ACSL4 expression, culminating in cell death. This compound exhibits a considerable antitumor effect [1].

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].
