Design and synthesis of aryloxypropanolamine as β3-adrenergic receptor antagonist in cancer and lipolysis

Eur J Med Chem. 2018 Apr 25:150:757-770. doi: 10.1016/j.ejmech.2018.03.032. Epub 2018 Mar 17.

Abstract

β-adrenergic receptors (β-ARs) are broadly distributed in various tissues and regulate a panel of important physiological functions and disease states including cancer. Above all, β3-adrenergic receptor (β3-AR) plays a significant role in regulating lipolysis and thermogenesis in adipose tissue. In this study, we designed and synthesized a series of novel L-748,337 derivatives as selective human β3-AR antagonists. Among all the tested L-748,337 analogs, compound 23d was found to display 23-fold more potent β3-AR antagonist activity (EC50 = 0.5117 nM) than L-748,337 (EC50 = 11.91 nM). In vivo, compound 23d could alleviate weight loss and inhibit tumor growth in C26 tumor cachexia animal model.

Keywords: Antagonist; Cancer; Lipolysis and cachexia; β-Adrenergic receptor.
