Biological Activity

Febuxostat (Uloric) is a non-purine selective xanthine oxidase inhibitor with IC50 of 114 -210 nM. It works by non-competitively blocking the molybdenum pterin center which is the active site on xanthine oxidase. Xanthine oxidase is needed to successively oxidize both hypoxanthine and xanthine to uric acid. Hence, febuxostat inhibits xanthine oxidase, therefore reducing production of uric acid. Febuxostat inhibits both, oxidized as well as reduced form of xanthine oxidase because of which febuxostat cannot be easily displaced from the molybdenum pterin site.

Method apoptosis assay
Cell Lines H/R and H/R + Veh cells
Concentrations 1 and 10 μM
Incubation Time 24 h
Results 24 h In comparison with Sham group, I/R treatment increased the apoptotic index (34.9 ± 2.6 vs. 4.5 ± 0.9%, P < 0.01). Pretreatment with either febuxostat or allopurinol effectively attenuated the increase in apoptotic index (Febuxostat: 26.9 ± 3.7 vs. 34.9 ± 2.6%; Allopurinol: 29.4 ± 1.9 vs. 34.9 ± 2.6%, P < 0.01, respectively).

Results Febuxostat treatment effectively blocked the increase of CK and LDH activities compared with I/R mice (CK: 121.9 ± 16.6 vs. 196.3 ± 15.3 mU/ml; LDH 765.5 ± 166.1 vs. 1549.8 ± 365.8 mU/ml; P < 0.01, respectively), similar to allopurinol (CK: 138.2 ± 7.18 vs. 196.3 ± 15.3 mU/ml; LDH: 1005.9 ± 53.1 vs. 1549.8 ± 365.8 mU/ml; P < 0.01, respectively).

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
