Abstract

Purpose: To investigate the anti-hyperammonemic activity of naringin by molecular docking via in silico studies.
Methods: Urea cycle proteins were docked to the natural compound naringin as well as a standard drug, sodium benzoate. Hydrogen bonds and binding energy were obtained using Catalytic Site Atlas and Cast P Finder Software Tool.
Results: There were six urea cycle enzymes, including N-acetyl glutamate synthase, carbamoyl phosphate synthase I, ornithine transcarbamylase, argininosuccinate synthase, argininosuccinate lyase and arginase I. On evaluating protein interactions with naringin, which is dynamically  connected to the urea cycle pathway with hyperammonemia, naringin showed more hydrogen bonds and also produced higher binding energy when compared to the standard drug, sodium benzoate.
Conclusion: The results of the molecular docking study show that naringin interacts with urea cycle enzymes with more hydrogen bonds and higher bonding energy than the standard drug, sodium benzoate. This supports the hypothesis that naringin can prevent experimental hyperammonemia.
