To study the anti-hyperuricemic efficacy, assess the safety of compound CC18013, and explore its possible mechanism related to xanthine oxidase (XOD) inhibition.
By establishing the acute and chronic hyperuricemic mice models and use of febuxostat as the positive control drug, the effect of CC18013 on serum uric acid levels was detected; the XOD inhibiting ability of CC18013 was determined using in vitro XOD model. The effect of CC18013 on serum and tissue XOD activity in hyperuricemic mice was measured. The interaction between CC18013 and XOD was analyzed by molecular-docking. The body weight change and general state of the mice were observe after a single dose treatment of CC18013.
CC18013 dose-dependently reduced serum uric acid levels in vivo, with the lowest effective dose of 0.5 mg·kg-1. Its IC50 value of XOD inhibition in vitro was 4.6 nmol·L-1. Moreover, it significantly inhibited XOD activity in liver and small intestine. Molecular-docking result indicated that it had a strong interaction with XOD. It showed no evident toxicity under the single dose of 500 mg·kg-1.
CC18013 is an XOD inhibitor with strong anti-hyperuricemic effect and high safety.
