| dc.description.abstract | Background: Hypertension is one of the most common cardiovascular diseases and
requires long-term treatment with synthetic drugs, which carry the risk of side
effects. Therefore, the use of bioactive peptides derived from plant sources such as
buckwheat (Fagopyrum esculentum) is an alternative as an Angiotensin Converting
Enzyme (ACE) receptor inhibitor.
Objective: This study aims to predict the potential of bioactive peptides resulting
from the hydrolysis of 13S globulin and albumin proteins from Fagopyrum
esculentum seeds using pepsin enzyme as an Angiotensin Converting Enzyme
(ACE) inhibitor in silico.
Methods: This study was conducted by examining predictions of biological activity,
physicochemical properties, pharmacokinetics, allergenicity, and toxicity, as well
as molecular docking simulations on ACE receptors.
Result: Based on the research results, out of 161 peptides obtained from hydrolysis,
there were 121 13S globulin peptides and 40 albumin peptides that had the potential
to be ACE inhibitors. Some of the peptides met Lipinski's Rule of Five criteria and
pharmacokinetic parameters, while others had non-toxic and non-allergenic
properties. The binding affinity values from the docking results ranged from -4,39
to -9,37 kcal/mol, with the IPSPA peptide showing the best binding affinity value
of -7,83 kcal/mol and important amino acid residue interactions similar to the native
ligand and comparator.
Conclusion: Peptides resulting from the hydrolysis of 13S globulin protein and
albumin from Fagopyrum esculentum seeds using pepsin enzyme have potential as
a source of bioactive peptides that inhibit ACE in silico. | |
