Molecular modulation of muscarinic antagonists. Synthesis and affinity profile of 2,2-diphenyl-2-ethylthio-acetic acid esters designed to probe the binding site cavity

Add time:07/25/2019    Source:sciencedirect.com

The synthesis and preliminary pharmacological profile of a new series of muscarinic antagonists, derived from previously studied 2,2-diphenyl-2-ethylthio-acetic acid esters, are reported. The parent molecules were decorated with linkers of different length, carrying an amino group to catch a putative anionic function outside the recognition site of the receptor. It was hoped that the interception of this function would give molecules with higher potency and selectivity. The attempt has not been successful, but a new series of compounds with a peculiar pharmacological profile has been identified.
