Our understanding of the regulation of appetite and energy balance has advanced significantly over the past decade as several peptides, centrally or peripherally expressed, have been characterized and shown to profoundly influence food intake and energy expenditure. (1)The growing number of putative appetite-regulating neuropeptides includes peptides that are orexigenic (appetite-stimulating) signals and anorectic peptides. Neuropeptide Y (NPY), melanin concentrating hormone (MCH), orexins A and B, galanin, and agouti -related peptide (AgRP) all act to stimulate feeding while alpha-melanocyte stimulating hormone (alphaMSH), corticotropin releasing hormone (CRH), cholecystokinin (CCK), cocaine and amphetamine regulated transcript (CART), neurotensin, glucagon-like peptide 1 (GLP 1), and bombesin have anorectic actions.(1) Leptin, expressed in the periphery in white adipose tissue, acts in the CNS to modulate the expression of several of these hypothalamic peptides.(1) This creates a functional link between the adipose tissue and the brain that translates the information on body fat provided by leptin to input into energy balance regulating processes. In the current review we examine the significant role of the melanocortin system (alphaMSH, agouti and AgRP peptides, and their receptors and mahogany protein) and melanin concentrating hormone in the regulation of energy balance.

Public health efforts and current antiobesity agents have not controlled the increasing epidemic of obesity. Investigational antiobesity agents consist of 1) central nervous system agents that affect neurotransmitters or neural ion channels, including antidepressants (bupropion), selective serotonin 2c receptor agonists, antiseizure agents (topiramate, zonisamide), some dopamine antagonists, and cannabinoid-1 receptor antagonists (rimonabant); 2) leptin/insulin/central nervous system pathway agents, including leptin analogues, leptin transport and/or leptin receptor promoters, ciliary neurotrophic factor (Axokine), neuropeptide Y and agouti-related peptide antagonists, proopiomelanocortin and cocaine and amphetamine regulated transcript promoters, alpha-melanocyte-stimulating hormone analogues, melanocortin-4 receptor agonists, and agents that affect insulin metabolism/activity, which include protein-tyrosine phosphatase-1B inhibitors, peroxisome proliferator activated receptor-gamma receptor antagonists, short-acting bromocriptine (ergoset), somatostatin agonists (octreotide), and adiponectin; 3) gastrointestinal-neural pathway agents, including those that increase cholecystokinin activity, increase glucagon-like peptide-1 activity (extendin 4, liraglutide, dipeptidyl peptidase IV inhibitors), and increase protein YY3-36 activity and those that decrease ghrelin activity, as well as amylin analogues (pramlintide); 4) agents that may increase resting metabolic rate ("selective" beta-3 stimulators/agonist, uncoupling protein homologues, and thyroid receptor agonists); and 5) other more diverse agents, including melanin concentrating hormone antagonists, phytostanol analogues, functional oils, P57, amylase inhibitors, growth hormone fragments, synthetic analogues of dehydroepiandrosterone sulfate, antagonists of adipocyte 11B-hydroxysteroid dehydrogenase type 1 activity, corticotropin-releasing hormone agonists, inhibitors of fatty acid synthesis, carboxypeptidase inhibitors, indanones/indanols, aminosterols, and other gastrointestinal lipase inhibitors (ATL962). Finally, an emerging concept is that the development of antiobesity agents must not only reduce fat mass (adiposity) but must also correct fat dysfunction (adiposopathy).
