The present aim of this investigation was to evaluate the effect of catechin from faba beans on oxidative stress and glucose uptake in yeast cells. Flow cytometry approach indicated that 2-NBDG (1.98 ± 0.37) seed extract had a lower relative fluorescence signal than methanol (5.98 ± 0.67) and acetone seed extract (4.43 ± 0.55). In comparison to the control and seed extract, HOexposure increased the apoptosis rate of yeast cells from 8.20% to 64.80%. Yeast cells incubated with HOproduced significantly more ROS intensity (162 ± 4.32, < 0.05) than control cells (118 ± 2.52, < 0.05) and less than seed extract-treated cells. Molecular dynamics simulation studies were performed for cat:α-amylase (catechin-α-amylase complex) which revealed the stable and mixed mode of inhibition during a simulation. The synergistic action of polyphenols or catechin present in seed extract may be responsible for the anti-oxidative stress and hypoglycaemic effects. The findings of this study may provide insight into the further development of a novel antidiabetic drug for T2DM. Communicated by Ramaswamy H. Sarma.
