Abstract

Ursolic acid (UA) is a triterpenoid isolated from Chinese herbal medicine. It is extensively distributed in the plant kingdom in at least 63 Chinese herbal medicines of 26 families. UA has multiple bioactivities, including anti‑viral hepatitis, antitumor, anti‑oxidation, anti‑bacterium and anti‑inflammation. The aim of this in vitro study was to examine the effects of UA on diabetes‑induced nephropathy and its possible mechanism. In mice with diabetes‑induced nephropathy, UA increased the body weight, reduced kidney/body weight index, protected kidney cells, alleviated inflammation [tumor necrosis factor (TNF)‑α, interleukin (IL)‑1β, IL‑6 and IL‑18 levels] and kidney cell damage. It was also indicated that UA suppressed Toll‑like receptor 4 (TLR4), myeloid differentiation factor 88 and nuclear factor‑κB protein expression in mice with diabetes‑induced nephropathy. The inhibition of TLR4 increased the anti‑inflammation of UA on inflammation in rat with diabetes‑induced nephropathy through the TLR4 signaling pathway. In conclusion, UA alleviates inflammation and inhibits diabetes‑induced nephropathy through a TLR4‑mediated inflammatory pathway. The present findings indicated that UA may be a possible therapeutic agent against diabetic nephropathy.
