The research presented in this book is comprised of two parts. Part A is related to research focused on protein glycation which is one of the major causes of diabetic complications. standard bio-assay was established to screen natural and synthetic compounds to discover new lead molecules with high potency and low toxic effects. More than 1000 compounds were investigated and detailed studies were performed. As a result several promising inhibitors of protein glycation belonging to different classes were identified and their cytotoxic effects were determined for their safer use. Part B of this...
