Abstract

Two series of compounds, 2 and 3, were synthesized and their binding affinities were evaluated for the human recombinant muscarinic M(1) receptor subtype expressed in CHO cells. Comparing their binding affinities for the NMS binding sites and the Oxo-M binding sites, they were assumed as agonists. In particular, compound 2e was a good ligand for the agonist binding sites with an IC(50) of 23 nM, which represents over 1585 times stronger binding than for the antagonist binding sites.
