A series of tertiaryamine analogs derived from lead azaaromatic quaternaryammoniumsalts has been designed and synthesized. The bis-tertiary amine analog exhibited an IC of 0.95nM, while the tris-tertiary amine analog had an IC of 0.35nM at nAChRs mediating nicotine-evoked dopamine release.

of azaaromatic quaternary ammonium analogs has been discovered as potent and selective α9α10nicotinicacetylcholinereceptor (nAChR) antagonists. The preliminary structure–activity relationships of these analogs suggest that increased rigidity in the linker units results in higher potency in inhibition of α9α10 nAChRs and greater selectivity over α7 nAChRs. These analogs represent a new class of analgesic
