Abstract
Hypertension (HTN) still constitutes a worldwide problem to the
healthcare section and individual’s life. The current angiotensin
converting enzyme (ACE) inhibitors are first-choice option but pose
deleterious side effects upon prolonged administration. The goal of the
present in silico study is to evaluate the Allium sativum and Solanum
lycopersicum proteins as source for anti-hypertensive natural peptides.
The corresponding protein sequences were obtained from the UniProt
database and then inputted to antihypertensive peptides predictor
online tool. Using the same tool, 3 digestive enzymes (pepsin, trypsin
and elastase 1) were chosen for the digestion of proteins into small peptides
and subsequently assess their hypotensive activity. Some biochemical
characteristics of positive bioactive peptides were calculated via
Pepstats web interface while HAPPENN tool examined hemotoxicity.
Afterwards, the secondary structure of positive bioactive peptides was
de novo predicted through PEPstrMOD server prior to docking against
human ACE (PDB ID: 1o86) using HPEPDOCK and ClusPro platforms.
A.sativum peptides are more potent than S.lycopersicum ones in
terms of IC50 as well as docking score albeit neither of which showed
hemotoxicity. The present in silico work suggests the hypotensive
activity of A.sativum and S.lycopersicum as natural treatment option
of HTN.
