Abstract
A new sensitive cyclic voltammetry method was developed for measuring the α-amylase inhibitory activity of six antidiabetic drugs commonly prescribed for type 2 diabetes: acarbose, amaryl, repaglinide, diamecron, dapagliflozin, and metformin. The electrochemical response of an enzyme-starch mixture was measured in the absence and presence of these drugs. Results indicated varying inhibitory potencies with IC50 values ranging from 6.770 to 41.423 µM, with acarbose as the most potent. UV-Vis absorption spectroscopy at 580 nm validated the cyclic voltammetry results, with very good concordance. This study highlights the utility of electrochemical assays for the rapid, quantitative screening of α-amylase inhibitors and supports their integration with spectroscopic methods for the evaluation of antidiabetic drugs.
