Abstract:

Ursolic acid, a pentacyclic triterpene compound with low toxicity and easy availability, has a variety of biological activities, including antitumor, antioxidant, antihepatitis, anti‑inflammatory and antibacterial effects. The present study aimed to investigate the renoprotective effects of ursolic acid on ischemia/reperfusion‑induced acute kidney injury (I/R‑IAKI) in rats associated with its antioxidant and anti‑inflammatory effects, as well as interference with the signal transducer and activator of transcription (STAT)3/nuclear factor (NF)‑κB signaling pathway. The present study demonstrated that pre‑treatment with ursolic acid significantly increased renal functioning and attenuated increases of serum angiotensin II levels in rats subjected to I/R‑IAKI. In addition, I/R‑IAKI‑induced inflammation and oxidative stress were significantly reduced by pre‑treatment with ursolic acid. Furthermore, ursolic acid significantly suppressed the upregulation of STAT3, NF‑κB and caspase‑3 activities in rats following I/R‑IAKI. These results indicated that ursolic acid may be a potential drug for reducing I/R‑IAKI through suppression of inflammation and oxidative stress damage, as well as modulation of STAT3 and NF‑κB activities.
