Abstract: xanthine oxidoreductase(XOR)is a member of the molybdoenzyme family and best known for its catalytic role in purine degradation , metabolizing hypoxanthine and xanthine to uric acid with concomitant generation of superoxide and hydrogen peroxide.In addition to its role in the pathophysiology of hyperuricaemia and gout , the role for XOR beyond purine metabolism was first suggested in ischaemia-reperfusion injury , there is growing evidence that it also participates in endothelial dysfunction,hypertension and heart failure.Importantly , the XOR inhibitor attenuates dysfunction especially in heart failure caused by XOR in these disease states.Attention to the broader range of XOR bioactivity in the cardiovascular system has prompted strong interest based XOR drug development by pharmaceuticals company.

Key words: xanthine oxidoreductase, reactive oxygen species, ischaemia-reperfusion injury, heart failure, drug development
