Article Abstract

Melanin-concentrating hormone (MCH) regulates feeding and energy homeostasis through interaction with its receptor, the melanin-concentrating receptor 1 (MCHR1), making it a target in the treatment of obesity. Molecular modeling and docking studies were performed in order to find a binding model for the docking of two new series of MCHR1 antagonists to the receptor. Results suggested interactions between the ligands and two glutamines (Gln5.42 and Gln6.55) not conserved in many of the GPCRs family members. Histamine 3 receptor (HRH3) presents two apolar residues in the aforementioned positions and the available biological data against this receptor supported the role of the two glutamines in the binding of antagonists to the MCHR1. This knowledge could be useful in the development of new, more active and more selective MCHR1 antagonists.
