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.

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

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

ML162 is an inhibitor of GPX4 that is selectively lethal to mutant RAS oncogene-expressing cell lines (IC50s = 25 and 578 nM for HRASG12V-expressing and wild-type BJ fibroblasts, respectively)

ML-210 (CID 49766530) is a selective RAS and covalent glutathione peroxidase 4 (GPX4) inhibitor(GPX4, EC50 : 30 nM), with anti-cancer activity

Mitiperstat is a potent myeloperoxidase (MPO) inhibitor that is effective in preventing cardiovascular diseases such as heart failure and coronary artery disease.

Verdiperstat (AZD 3241) is a selective, irreversible and orally active myeloperoxidase inhibitor, with an IC50 of 630 nM, and can be used in the research of neurodegenerative brain disorders.

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].

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

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

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

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

Cefdinir (FK-482) is a semi-synthetic, broad-spectrum antibiotic in the third generation of the cephalosporin class, proven effective for common bacterial infections of the ear, sinus, throat and skin.

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.

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, concurrently reducing hydrogen peroxide or lipid peroxides to water. This enzyme serves as a potent antioxidant, protecting against oxidative stress [1].
