Acetyl-11-Keto-β-Boswellic Acid and Incensole Acetate Attenuate Lipopolysaccharide-Induced Acute Kidney Injury by Inhibiting Inflammation and Oxidative Stress

Boswellia serrata has been used in traditional medicine to treat various inflammatory diseases. Acetyl-11-keto-beta-boswellic acid (AKBA) and incensole acetate (IA) are two active ingredients of B. serrata that possess anti-inflammatory and antioxidant activities. The present study aimed to investigate the protective effects of AKBA and IA against lipopolysaccharide (LPS)- induced acute kidney injury (AKI) in rats. Wistar rats were intraperitoneally pretreated with AKBA or IA for 2 weeks. After 30 min, an LPS injection was applied to induce AKI. Blood samples and kidney tissues were collected and used for biochemical assays. AKBA and IA not only significantly decreased interleukin-6 as a marker of renal inflammation but also attenuated the oxidative stress markers in kidney tissues. AKBA and IA also remarkably decreased serum creatinine and blood urea nitrogen. These results suggest that AKBA and IA have protective effects against AKI in rats through regulating inflammation and oxidative stress.
