Synthesis, molecular modeling and biological evaluation of novel 2-allyl amino 4-methyl sulfanyl butyric acid as α-amylase and α-glucosidase inhibitor

• Synthesized a novel compound of AMSB.
• Investigated antioxidant and antidiabetic activity.
• Performed kinetic study.
• Docking study.

In the present study 2-allyl amino 4-methyl sulfanyl butyric acid (AMSB) was synthesized in good yield. AMSB was characterized by Fourier transforms infrared spectroscopy (FTIR), Nuclear magnetic resonance (NMR) (1H and 13C) and Liquid chromatography mass spectrometry (LCMS). The radical scavenging activity and reducing power assay of AMSB was assessed using 1-1-diphenyl 2-picryl hydrazyl (DPPH), 2,2′-azino-bis (3-ethyl benzothiazoline-6-sulfonic acid) (ABTS) and ferric ion reducing antioxidant power assay (FRAP) and was found to be 44.1, 34.71 and 41.7 μg/ml respectively. The compound showed effective inhibition against α-amylase and α-glucosidase. AMSB was identified to be a reversible mixed noncompetitive inhibitor of α-amylase and α-glucosidase. The molecular docking study was carried out to evaluate the specific groove binding properties and affords valuable information of AMSB binding mode in the active site of α-glucosidase the study may lead to the which leads to the rational design of new class of antidiabetic drugs targeting α-glucosidase based on AMSB in near future.
