Abstract

In this study, new benzoic acid derivatives of the quinazolinone ring, which is one of the biologically active members of nitrogen‐containing heterocyclic compounds, were synthesized with excellent yields (98–90 %). The structures of the novel compounds (

H NMR–
13
C NMR), and High‐Resolution Mass Spectroscopy (HRMS). α‐Glucosidase and α‐Amylase inhibition properties were examined to evaluate the anti‐diabetic properties of the synthesized compounds. For α‐Glucosidase, molecules showed IC

s in ranging of >100–3.310±0.326 μM. For α‐Amylase, molecules showed IC

in ranging of >100–1.215±0.225 μM. 4‐[(2‐[(4‐phenylpiperazin‐1‐yl)methyl]‐4‐oxoquinazolin‐3(4
H
)‐ylimino)methyl]benzoicacid (

) has the strongest inhibitory effect for both enzymes. It is 5.4 times more potent inhibitor for α‐Glucosidase and 34.9 times more potent for α‐Amylase than the standard inhibitor Acarbose. Also, the molecular docking study was carried out for the most active compound for the determination of ligand‐enzyme interactions. Binding affinities of the most active compound were calculated as −5.978 kcal/mol and −5.548 kcal/mol for α‐Glucosidase and α‐Amylase, respectively. The aromatic ring and the aminomethyl group of the quinazoline and the carboxyl group moieties have played a critical role in the inhibition.
