Design and optimization of quinazoline derivatives as melanin concentrating hormone receptor 1 (MCHR1) antagonists

Bioorg Med Chem Lett. 2012 May 1;22(9):3157-62. doi: 10.1016/j.bmcl.2012.03.050. Epub 2012 Mar 23.


Melanin concentrating hormone (MCH) is an important mediator of energy homeostasis and plays a role in metabolic and CNS disorders. The modeling-supported design, synthesis and multi-parameter optimization (biological activity, solubility, metabolic stability, hERG) of novel quinazoline derivatives as MCHR1 antagonists are described. The in vivo proof of principle for weight loss with a lead compound from this series is exemplified. Clusters of refined hMCHR1 homology models derived from the X-ray structure of the β2-adrenergic receptor, including extracellular loops, were developed and used to guide the design.
