Abstract |
Due to the explosive increase in the number of people diagnosed with diabetes world-wide in the past two decades, we can now speak of diabetes epidemic even if this word seems inappropriate in conjunction with a chronic disease. Diabetes is now considered as one of main threats to human health in the 21-st century. It is a metabolic disorder primarily characterized by insulin resistance and elevated blood glucose levels. Insulin resistance and glucose intolerance are key elements of the metabolic syndrome, which is currently associated with impaired function of PPAR gamma nuclear receptor and excessive production of fat tissue hormones. PPAR gamma is critical transcription factor in regulating lipid and glucose metabolism as well as insulin sensitivity, thus PPAR gamma receptor is considered as a very promising molecular target for developing new antidiabetic compounds. New investigated compound is a phenylpropanoic acid derivative (non-thiazolidinedione), selective, partial agonist of PPAR gamma nuclear receptor. As a partial PPAR gamma agonist, new compound has less than 30% of the activity associated with currently marketed full PPAR gamma agonist, rosiglitazone. Theoretically, our partial agonist should minimize side effects associates with rosiglitazone treatment by limiting the spectrum of activation of PPAR gamma. Consistent with this prediction, animal studies have revealed that the compound is effective in lowering blood glucose levels and demonstrates a relatively benign adverse event profile at putative therapeutic dose ranges. Doses used in animal models of diabetes such as the db/db mouse and the ZDF rat showed significant efficacy in the control of blood glucose level with minimized body weight gain, when compared to rosiglitazone. Moreover safety pharmacology and toxicology studies with mice, rats, dogs and monkeys suggest a broad safety window in which to study new compound’s benefits in humans. |
