S6648	PF-06282999	PF-06282999 is an orally bioavailable, irreversible inactivator of myeloperoxidase enzyme and is currently in clinical trials for the potential treatment of cardiovascular diseases.	J Chromatogr B Analyt Technol Biomed Life Sci, 2021, 1181:122924
E1375	JKE-1674	JKE-1674 is an analog of ML-210 in which the nitroisoxazole ring is replaced with an -nitroketoxime. It is an orally active inhibitor of glutathione peroxidase 4 (GPX4) and also is an active metabolite of GPX4 inhibitor ML-210. JKE-1674 can convert into a nitrile oxide JKE-1777.	Redox Rep, 2025, 30(1):2440204
E1244	FINO2	FINO2 is a potent ferroptosis inducer which inhibits GPX4 activity. This compound causes widespread lipid peroxidation.
S0316	MPO-IN-28	MPO-IN-28 (Compound 28) is an inhibitor of myeloperoxidase (MPO) with IC50 of 44 nM.
S4966	4-Methylesculetin	4-Methylesculetin is one of the coumarin derivatives with great anti-oxidant and anti-inflammatory activities. 4-Methylesculetin inhibits myeloperoxidase (MPO) activity and reduces IL-6 level.
E2989^New	AZD5904	AZD5904 is a selective and irreversible human Myeloperoxidase (MPO) inhibitor. AZD5904 reduces 3-chlorotyrosine-modified MYBPC3 levels, restores MYBPC3 phosphorylation, and alleviates the calcium signalling and relaxation defects.
S3274	Glucosyl-vitexin	Glucosyl-vitexin (Glucosylvitexin), the major C-glycosylflavone present in millet, inhibits thyroid peroxidase (TPO) activity.
S3299	Demethyleneberberine	Demethyleneberberine (DMB), a component of Cortex Phellodendri Chinensis (CPC), significantly alleviates the weight loss and diminishes myeloperoxidase (MPO) activity, while significantly reduces the production of pro-inflammatory cytokines, such as interleukin (IL)-6 and tumor necrosis factor-α (TNF-α), and inhibits the activation of NF-κB signalling pathway. This compound potentially ameliorates NAFLD (Non-alcoholic fatty liver disease) by activating AMPK pathways.
S8155	RSL3	RSL3 ((1S,3R)-RSL3) is a ferroptosis activator in a VDAC-independent manner, exhibiting selectivity for tumour cells bearing oncogenic RAS. RSL3 binds, inactivates GPX4 and thus mediates GPX4-regulated ferroptosis.
