Development of Melanin Concentrating Hormone Receptor R1 Antagonists for the Pharmacological Treatment of Obesity

Gildardo Rivera, Antonio Monge and Virgilio Bocanegra-Garcia

Abstract

In this chapter we review the development of melanin concentrating hormone receptor 1 (MCH-R1) antagonists as a new perspective for the pharmacological treatment of obesity. We will initially focus on melanin concentrating hormone (MCH): structure, localization and function in the regulation of feeding behavior and energy balance and two receptors for MCH in humans. We will then review the discovery of the first MCH-R1 antagonists, the drug-design strategies used to obtained new series of MCH-R1 antagonists and an analysis of their structure-activity relationship. Finally, we will evaluate the absorption, distribution, metabolism and excretion, efficacy, safety and toxicity in preclinical and clinical trials.
