The aim of the present study was to analyse the antidiabetic and antioxidant potential of GancidinW (GW) extracted from Streptomyces paradoxus VITALK03.
Materials and Methods:
Antidiabetic potential of GW was evaluated by assay of α-amylase and α-glucosidase inhibitory activity; haemoglobin glycosylation and yeast glucose uptake. The antioxidant potential of GW was assessed by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay, 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation decolorization assay and superoxide assay. The inhibition of α-amylase and α-glucosidase by GW was also studied by in Silico molecular docking analysis.
GW (1mg/ml) showed 69.32% of α-amylase and 54.04% of α-glucosidase inhibitory activity. GW (1mg/ml) prevented haemoglobin glycosylation up to 30.92% and the glucose uptake by yeast cells was increased up to 64.38%. The binding interaction GW with α-amylase showed the least free binding energy of -6.09Kcal/mol and -7.53Kcal/mol with α-glucosidase by docking studies. GW also demonstrated moderate antioxidant activity in all the antioxidant assays performed.
The results of this study suggests that the antidiabetic and antioxidant potential of GW can be probed further to develop GW as effective antidiabetic agent.
