摘要

Chrysanthemum indicum Linne flower (CF) and Cinnamomum cassia (L.) J. Presl bark (CB) extracts have been used as the main ingredients in several prescriptions to treat the hyperuricemia and gout in traditional medicine. In the present study, we investigated the antihyperuricemic effects of DKB114, a CF, and CB mixture, and the underlying mechanisms in vitro and in vivo. DKB114 markedly reduced serum uric acid levels in normal rats and rats with PO-induced hyperuricemia, while increasing renal uric acid excretion. Furthermore, it inhibited the activity of xanthine oxidase (XOD) in vitro and in the liver in addition to reducing hepatic uric acid production. DKB114 decreased cellular uric acid uptake in oocytes and HEK293 cells expressing human urate transporter (hURAT)1 and decreased the protein expression levels of urate transporters, URAT1, and glucose transporter, GLUT9, associated with the reabsorption of uric acid in the kidney. DKB114 exerts antihyperuricemic effects and uricosuric effects, which are accompanied, partially, by a reduction in the production of uric acid and promotion of uric acid excretion via the inhibition of XOD activity and reabsorption of uric acid. Therefore, it may have potential as a treatment for hyperuricemia and gout.

Presl树皮(CB)提取物已在多种处方中用作治疗传统医学中高尿酸血症和痛风的主要成分。在本研究中,我们研究了DKB114,一种CF和CB混合物的抗高尿酸作用以及其在体内和体外的潜在机制。 DKB114显着降低正常大鼠和PO诱导的高尿酸血症大鼠的血清尿酸水平,同时增加肾脏尿酸排泄。此外,它在抑制肝脏黄嘌呤氧化酶(XOD)活性的同时,还减少了肝脏尿酸的产生。 DKB114降低表达人尿酸转运蛋白(hURAT)1的卵母细胞和HEK293细胞中细胞尿酸的摄取,并降低尿酸转运蛋白URAT1和葡萄糖转运蛋白GLUT9的蛋白表达水平,这与肾脏中尿酸的重吸收有关。 DKB114发挥抗高尿酸的作用和尿酸尿酸作用,部分地是通过抑制XOD活性和重吸收尿酸来减少尿酸的产生并促进尿酸的排泄。因此,它可能具有治疗高尿酸血症和痛风的潜力。
