Hepato & nephro protective effects of naringenin-loaded tpgs polymeric nanosuspension against cisplatin-induced toxicity
Cisplatin (Cis-Diammineplatinum (II) dichloride/CIS) is one of the most potent chemotherapeutic agents widely used in treatment of various cancers. Naringenin (NAR), a natural flavonoid, protect against CIS-induced injury in rats without hampering CIS beneficial cytotoxic activity. Even though NAR exhibits therapeutic potency, clinical evolution of the molecule is embarrassed because of very less aqueous solubility which corresponds to low availability at the site of the tumor. In our former analysis, nanosuspension of naringenin (NARNS) was developed by the method of high-pressure homogenization. The study had been continued to evaluate the protective role of D-α-Tocopheryl polyethylene glycol succinate (TPGS) coated NARNS, against oxidative stress-induced hepato and nephrotoxicity in male Wistar rats upon CIS treatment. Induction of acute hepato and neprotoxicity was done by intraperitoneal injection (i.p) injection of CIS (7 mg/kg of body weight) and administration of NAR and NARNS. Administration of NARNS virtually suppressed CIS-induced and liver injury evidenced by a reduction of lipid peroxidation level, blood urea nitrogen, serum uric acid, creatinine and elevated enzymatic antioxidant activities of superoxide dismutase, catalase, and glutathione peroxidase in rats liver tissue. Histological studies substantiated the biochemical parameters. The study suggests that NARNS has strong hepato and nephroprotective effect compared to NAR.
