Synthesis and biological activity of some new flavonyl-2,4-thiazolidinediones

A new series of flavonyl-2,4-thiazolidinediones (Va–c, VIa–c) was prepared by Knoevenagel reaction. The synthesized compounds were tested for their ability to inhibit rat kidney aldose reductase (AR) and for their insulinotropic activities in INS-1 cells. Compound Vb was able to increase insulin release in the presence of 5.6 mmol/l glucose. Compounds VIa–c displayed moderate to high AR inhibitory activity levels. Particularly, compound VIa showed the highest AR inhibitory activity (86.57%).

A new series of flavonyl-2,4-thiazolidinediones were prepared by Knoevenagel reaction. The prepared compounds were tested for their aldose reductase inhibitory and insulinotropic activities.Figure optionsDownload as PowerPoint slide
