Antioxidant, anti-inflammatory and anti-apoptotic effects of amentoflavone on gentamicin-induced kidney damage in rats
Abstract
Gentamicin (GEN) is an extensively used aminoglycoside. Contrary to its antibacterial potential, it can induce oxidative stress in several organs, including kidney. Amentoflavone (AMN) is a biflavonoid with conspicuous pharmacological activities. The current study was held to estimate the curative efficacy of AMN to antagonize the nephrotoxic effects instigated by GEN. 48 albino rats were separated into four groups: control group, GEN administrated group (80 mgkg−1 intraperitoneally), GEN + AMN treated group (80 mgkg−1 + 40 mgkg−1) and only AMN administrated group (40 mgkg−1). Following 30 days of administration, results showed that GEN disturbed antioxidant enzymes i.e., glutathione (GSH), glutathione reductase (GSR), glutathione peroxidase (GPx), glutathione S-transferase (GST), superoxide dismutase (SOD), catalase (CAT) activity, besides elevated malondialdehyde (MDA) along with reactive oxygen species (ROS) level. Besides this, level of inflammatory cytokines involving interleukin-6 (IL-6), nuclear factor-kappa B (NF-κB), interleukin-1 beta (IL-1β), tumor necrosis factor alpha (TNF-α) & cyclo-oxygenase-2 (COX-2) were escalated. Furthermore, treatment with GEN enhanced the level of apoptotic proteins comprising of Bax, caspase-9 along with caspase-3 besides lessened the level of Bcl-2. In addition to this, GEN reduced the level of albumin, creatinine clearance & augmented the level of creatinine, urea, urobilinogen, urinary protein, kidney injury molecules-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL) as well as instigated various histopathological damages. However, co-treated group (AMN + GEN) revoked abovementioned renal dysregulations instigated by GEN. Taken together, AMN could significantly counteract GEN-instigated nephrotoxic effects due to its antioxidant capabilities.
