Abstract:
Reactive oxygen species by uncoupled eNOS is linked to endothelial dysfunction. Ellagic acid (EA), a polyphenol possesses
numerous biological activities including radical scavenging. whether EA exerts a vasculo-protective efect via antioxidant
mechanisms in blood vessels remains unknown. Molecular docking provides an initial model of protein and molecular
interactions in various physiological and/or pathological functions. To identify a eNOS modulatory biomolecule through
molecular docking as possible vascular protective agent. On the basis of binding afnities and other physicochemical features,
a molecular docking-based approach was used to classify and evaluate eNOS binding micronutrients found in natural sources,
Lipinski’s rule was used taking into account their adsorption, delivery, metabolism, and excretion (ADME). An insilico
approach focused on the ligand–protein interaction technique to determine the therapeutic potential of certain phytochemicalbased drugs for the vascular remodelling.20 bioactive molecules were screened, docking analysis on human eNOS proteins
was performed. The best poses for target protein was established based on binding energy and inhibition constant. EA and
cafeine acid are the strongest candidates for eNOS protein functional norms. This provides a novel insight into the interaction properties of known human eNOS protein with EA and used as a therapeutic agent in various pathologies.
