  Synthesis and evaluation of xanomeline analogs—Probing the wash-resistant phenomenon at the M1 muscarinic acetylcholine receptor

  摘要：

  A series of xanomeline analogs were synthesized and evaluated for binding at the M, muscarinic acetylcholine receptor (M-1 receptor). Specifically, compounds that substitute the O-hexyl chain of xanomeline with polar, ionizable, or conformationally restricted moieties were assessed for their ability to bind to the M, receptor in a wash-resistant manner (persistent binding). From our screen, several novel ligands that persistently bind to the M, receptor with greater affinity than xanomeline were discovered. Results indicate that persistent binding may arise not only from hydrophobic interactions but also from ionic interactions with a secondary M, receptor binding site. Herein, a qualitative model that accounts for both binding scenarios is proposed and applied to understand the structural basis to wash-resistant binding and long-acting effects of xanomeline-based compounds.

  Series of analogs to the functional mi selective agonist, xanomeline (hexyloxy-TZTP), were evaluated for their in vitro ml efficacy in cell lines transfected with the human ml receptor. Systematic variation of the side chain and the azacyclic ring led to the discovery of potent muscarinic agonists with robust ml efficacy, ail having the phenylpropargyloxy/thio as the side chain. The most selective compound was the phenylpropargylthio-[3.2.1] endo analog 28, which is a potent and efficacious mi agonist with no m2 activity. (C) 1998 Elsevier Science Ltd. All rights reserved.
