Abstract:
Background: For the first time, the inhibitory effects on the human salivary alpha-amylase
activity of the anti-inflammatory drugs indomethacin, diclofenac sodium, ketoprofen, diclofenac
potassium, diclofenac, triamcinolone acetonide, and the antihistamine drugs levocetirizine
dihydrochloride, desloratadine, cycloheptadine hydrochloride, have been investigated to confirm
the other properties of these drugs.
Objective: This study aimed to determine the effect of nine known drugs on human salivary α-amylase
in vitro and the nature of interactions with structure-activity relationship using molecular docking
experiments.
Methods: The inhibition of human salivary alpha amylase by the six anti-inflammatory and three
antihistamine drugs has been carried out using the new method that has been proved in our previous
work. Molecular docking has been achieved for the first time for these drugs using the Auto-
Dock Vina program.
Results: Cyproheptadine hydrochloride presented the highest inhibitory activity against α-amylase
with IC50=0.7 mg/ml, while the other drugs showed weak activities (IC50 > 2 mg/ml).
Conclusion: We conclude that Cyproheptadine hydrochloride, which was studied by docking experiments,
exhibited the best inhibitory activity on salivary α-amylase in vitro & in silico.
