The Benefit of Passion Fruit as an Anti-ulcerogenic Diet: Scientific Evidence by In vitro and In silico H+/K+ATPase Inhibitory Activity Assessment
Abstract
BACKGROUND: H+/K+ ATPase a protein present in the gastric parietal cells is a better target for the prevention and treatment of gastric ulcer. Plant flavonoids have been reported to elicit anti-ulcer activity by inhibiting the proton pump as well as by antioxidant defense mechanism.
METHODS: Chloroform fraction of hydro-alcoholic extract of passion fruit was screened for proton pump inhibitory assay using goat parietal cell. In-silico computational docking studies were carried out using Glide program in order to validate the inhibitory action of selected constituents.
RESULTS: The flavonoid rich fruit possess a promising radical scavenging activity against DPPH. 10.41μg/mL is sufficient to inhibit 50% of ATPase enzyme activity. A synergistic activity was also achieved by the fruit with sub-effective doses of lansoprazole. Fenton's oxidation induced by H2O2 was also blunted by the fruit extract.
CONCLUSION: The in-vitro and in-silico findings indicated that, passion fruit can be a good dietary supplement for the prevention and management of ulcer.
