Xanthine Oxidase

Allopurinol is a purine analog; it is a structural isomer of hypoxanthine (a naturally occurring purine in the body) and is an inhibitor of the enzyme xanthine oxidase.

Baicalein is a flavonoid originally isolated from the roots of Scutellaria baicalensis Georgi. Baicalein inhibits lipid peroxidation, as assessed by production of TBARS, with an IC50 value of 5 µM.

Febuxostat is a non-purine inhibitor of xanthine oxidase (Ki = 1.2 nM).

Lobetyolin is isolated from the hairy roots of Lobelia inflata.

Oxipurinol (Oxipurinol), the major active metabolite of Allopurinol, is an inhibitor of xanthine oxidase. Oxipurinol can be used to regulate blood urate levels and treat gout.

Topiroxostat (FYX-051) is a novel and potent xanthine oxidoreductase (XOR) inhibitor with IC50 value of 5.3 nM.

Phytic Acid is a constituent of wheat bran shown to have antineoplastic action in colon carcinogenesis.

Benzbromarone is a CYP2C9 inhibitor, it binds to CYP2C9 with Ki value of 19.3 nM.

Febuxostat D9 is deuterium labeled Febuxostat, which is a selective xanthine oxidase inhibitor with Ki of 0.6 nM.

H-Tyr-Phe-OH (L-Tyrosyl-L-phenylalanine) is an orally active inhibitor of Angiotensin converting enzyme (ACE), with an inhibiton rate of 48% at 50 μM. H-Tyr-Phe-OH can be used as an biomarker for differentiating benign thyroid nodules (BTN) from thyroid cancer (TC). H-Tyr-Phe-OH exhibits xanthine oxidase inhibition (uric acid lowering) activity and serves as regulator in IL-8 production in neutrophil-like cells.
