Pimagedine, also known as aminoguanidine, is an investigational drug for the treatment of diabetic nephropathy that is no longer under development as a drug.[1] Pimagedine is a diamine oxidase and nitric oxide synthase inhibitor. It acts to reduce levels of advanced glycation end products (AGEs) through interacting with 3-deoxyglucosone.
