Obesity has reached epidemic proportions in industrialized countries, especially the United States, and is rapidly increasing in prevalence worldwide. Obesity is not a simply cosmetic concern, but a serious health problem. Thus, the World Health Organization (WHO) recently declared that obesity has become a global epidemic. Obesity is characterized by excess of body fat, and includes a pro-inflammatory state event Read More

In addition to its enormous impacts on an individual's quality of life, obesity is a daunting health problem in the world today and the increasing rate of obesity is now causing a severe burden on health care systems. Fortunately, the normalization or reduction of increased body fat reverses the obesity-associated morbidities, such as hypertension, glucose intolerance, dyslipidemia, and fatty liver diseases. However, the modificati Read More

Since the discovery of rimonabant (Acomplia: 1), a large effort has been directed at the discovery of new, potent and selective CB1R antagonists that serve as anti obesity drugs. As a result, a number of compounds reached various stages of clinical trials by late 2008. However, the announcement by Sanofi-Aventis that they were discontinuing all ongoing trials with rimonabant, as a result of the finding that risks asso Read More

Despite remarkable progress in the elucidation of energy balance and regulation, the development of new antiobesity drugs is still at the stage of infancy. Herein we briefly reviewed several investigational anti-obesity agents currently under development, consisting of agents controlling appetite, modulating nutrient absorption and lipid metabolism, sensing and regulating nutrient status, stimulating energy expenditure, a Read More

Many orphan G-protein-coupled receptors (GPCR) have emerged as potential obesity targets. The authors are interested in the computer-aided discovery and development of small molecule anti-obesity agents targeting GPCR. Computational modeling studies have mainly been conducted on ghrelin receptor (GHS-R), melanocortin 4-receptor (MC4R), melanin-concentrating hormone 1 receptor (MCH1R) and cannabinoid 1 rece Read More

Current biological and pharmacological evidence suggests that the melanocortin 4 and melanocortin 3 receptors which are seven transmembrane G-protein coupled receptors (GPCRs) are involved in various aspects of energy balance and feeding behaviors in animals including humans. The natural endogenous ligands for these receptors are products of the gene pro-opiomelanocortin (POMC), and include α-melanocyte stim Read More

The prevalences of overweightedness and obesity are increasing globally at frightening rates, driven by social and economic changes. Furthermore, obesity is associated with the pathogeneses of major diseases, particularly diabetes and cardiovascular diseases. However, no satisfactorily safe, effective obesity drugs are commercially available at the present time. Only two drugs have been approved in the United States for the l Read More
