Application

Oxypurinol, an allopurinol metabolite, is used as an inhibitor to study the specificity and kinetics of of xanthine oxidase(s). Oxypurinol is also used as an anti-inflammatory agent via inhibition of xanthine oxidase.
Oxypurinol has been used as a xanthine oxidase inhibitor, to evaluate its effects on hepatocellular carcinoma cell proliferation. It has also been used as a xanthine inhibitor to elucidate its contribution in the induction of hpv16 late gene expression.

Packaging

100, 500 mg in glass bottle

Biochem/physiol Actions

Oxypurinol has the ability to stimulate osteoblast differentiation and enhance the formation of bone. It is used to treat gout and hyperuricemia. Oxypurinol is considered as a strong antioxidant. It can prevent the actions of xanthine oxidase (XO) in osteoblasts.
An allopurinol metabolite.

Xanthine oxidase (XO) is a critical source of reactive oxygen species (ROS) that contribute to vascular inflammation. Binding of XO to vascular endothelial cell glycosaminoglycans (GAGs) results in significant resistance to inhibition by traditional pyrazolopyrimidine-based inhibitors such as allopurinol. Therefore
