Diabetes mellitus (DM) is a chronic metabolic disorder that seeks treatment instead of available mitigative therapy.
Six (E)-3-(aryl)-1-phenylprop-2-en-1-one chalcones were synthesized and characterized through various spectroscopic techniques. Their anti-diabetic potential was examined through in-vitro (α-glucosidase and α-amylase inhibition assays), in-vivo (alloxan-induced hyperglycemia), and in-silico studies.
All the chalcones derivatives significantly inhibited α-glucosidase and α-amylase. Compounds 11 (IC50 = 1.10 ± 0.02) and 13 (IC50 = 3.25 ± 0.10 µM) exhibited the most potent activity against α-glucosidase. The effect of compounds 11 and 13 was also significant against α-amylase with IC50 of 13.2 ± 0.50 and 10.2 ± 0.4 µM, respectively. In alloxan-induced hyperglycemic model, a significant (p<0.001) reduction in blood glucose level (BGL) was observed by compounds 10, 11 and 14 with maximum percent inhibition of 47.48, 47.22 and 47.55, respectively. In the oral glucose tolerance test, a continuous reduction in BGL was noted at 60 minutes. No negative effect was seen on lipid profile, and in liver and renal function tests. However, a slight gain in body weight was noted. Moreover, docking result indicates good interaction of these molecules with the target enzymes, α-glucosidase and α-amylase.
These results demonstrate that all these molecules have significant anti-diabetic potential.
