In vitro antiglycation and antioxidant properties of benzophenone thiosemicarbazones.

Fifteen benzophenone thiosemicarbazones were synthesized and their in vitro antiglycation activity was evaluated. The most active compound 2 (IC50 = 118.15 +/- 2.41 mu M) showed two folds potent activity than the standard, rutin (IC50 = 294.5 +/- 1.5 mu M). Compounds 1 and 3-7 showed good to moderate antiglycation activity in the range of 204.14 - 488.54 mu M. These compounds were also evaluated for antioxidant activity. Their structure-activity relationships have been developed. The results reveal the potential of these compounds as leads for further studies towards the development of antidiabetic drugs.
