Abstract: Synthesis of a series of urea and thiourea derivatives of glycine and proline conjugated to 2,3-dichlorophenyl piperazine has been reported. The structures were confirmed by physical and spectroscopical measurements followed by characterization of antiglycation activity. All synthesized compounds were able to inhibit protein glycation, particularly halogen containing derivatives without preference of oxygen or sulphur at the urea function. The best analogues are nearly 20 fold (< 5 µM) more potent than the reference standard, rutin (41.9 µM).
