Abstract
The therapeutic benefit of doxorubicin has led to a tremendous improvement in treating cancer. However, it has been associated with cardiotoxicity, renal, and hepatic toxicities, among others. Hence, the continuous search for natural scavengers of DOX-induced toxicity remains imperative. This study evaluated the hepatoprotective and nephroprotective effects of ethanol extracts of Urtica dioica (UD) leaves on doxorubicin-induced oxidative stress. This study comprised 5 groups: control, doxorubicin (DOX: 15 mg/kg), UD-treated group (DOX + 300 mg/kg), a second UD-treated group (DOX + 600 mg/kg), and UD-treated group (600 mg/kg alone). The in vitro antioxidant potential of UD was assayed with FRAP and DPPH, and GCMS-identified UD phytoconstituents were docked against NADPH oxidase (2CDU) and nitric oxide synthase (2FLQ) using molecular docking tools such as Discovery Studio, Open Babel, and PyRX. UD had a concentration-dependent FRAP better than BHT and a DPPH scavenging activity of IC50 265.96 g/ml. The DOX group had hepatic and renal alteration that was evident in the significant (p < 0.05) elevation of hepatic (AST and ALT) and renal (BUN, creatinine, Na+) markers with reduced antioxidant markers (GPx, CAT, GSH). The CRP level of the DOX group was also significantly (p < 0.05) higher than that of the control group. The UD-treated group (DOX + 300 mg/kg) showed a significant (p < 0.05) reduction in the CRP, hepatic, and renal biomarkers, with a significant improvement in the activities of the antioxidant markers. The selected UD compounds showed good binding affinities against 2CDU and 2FLQ. Beta-Bissabolene (-9.2 and -8.0 kg/mol) and Alpha-Terpineol (-7.7 and -7.0 kg/mol) have higher binding affinities and good hydrogen interactions with 2FLQ and 2CDU, with acceptable drug-likeness properties. Urtica dioica extract and its compounds showed great potential for preventing DOX-induced hepatotoxicity and nephrotoxicity through modulation and reduction of biomarkers of cellular toxicity and enhancement of endogenous antioxidant enzymes. Beta-Bissabolene and Alpha-Terpineol from UD, through molecular docking, showed to be very potent in preventing ROS-mediated oxidative stress; hence, they may be adopted as toxicity-preventive candidates in doxorubicin treatments.
