Allopurinol (Zyloprim) is a xanthine oxidase inhibitor with an IC50 of 7.82?.12 uM. Xanthine oxidase is responsible for the successive oxidation of hypoxanthine and xanthine resulting in the production of uric acid, the product of human purine metabolism. The inhibition of XO activity by 6-aminopurine (IC50=10.89?.13 uM) and its analogues was compared with that by allopurinol (IC50=7.82?.12 uM). Among these analogues, 2-chloro-6 (methylamino)purine (IC50=10.19?.10 uM) and 4-aminopyrazolo[3,4-d] pyrimidine (IC50=30.26?.23 uM) were found to be potent inhibitors of XO.
