ABSTRACT

Introduction:

2,4-Thiazolidinedione and its derivatives exhibit a variety of pharmacological activities including antidiabetic, antiviral, antifungal, anti-inflammatory, anti-cancer and aldose reductase inhibitory activities. Keeping in mind the pharmacological potential of 2,4-Thiazolidinedione derivatives as antidiabetic agents, seven arylidene derivatives of 2,4-thiazolidinedione 1(a-g) and four corresponding acetic acid derivatives 2(a-d) have been synthesized by a three-step procedure.

Methods:

All the synthesized compounds were characterized by elemental analysis, FTIR, 1HNMR, and 13CNMR and further screened for their α-amylase inhibitory potential.

Results:

All the compounds 1(a-g) and 2(a-d) showed varying degree of α-amylase inhibition, especially compound 1c (IC50 = 6.59μg/ml), 1d (IC50=2.03μg/ml) and 1g (IC50 = 3.14μg/ml) displayed significantly potent α-amylase inhibition as compared to the standard acarbose (IC50 = 8.26μg/ml). None of the acetic acid derivatives of 5-arylidene-2,4-thiazolidinedione showed prominent inhibitory activity. Docking results indicated that the best binding conformation was found inside the active site cleft of enzyme responsible for hydrolysis of carbohydrates.

Conclusion:

Therefore, it can be concluded that 2,4-thiazolidinedione derivatives can be used as effective lead molecules for the development of α-amylase inhibitors for the management of diabetes.
