Abstract
Nicotinic acetylcholine receptors containing α9 subunits (α9*-nAChRs) are potential druggable targets arousing great interest for pain treatment alternative to opioids. Nonpeptidic small molecules selectively acting as α9*-nAChRs antagonists still remain an unattained goal. Here, through modifications of the cationic head and the ethylene linker, we have converted the 2-triethylammonium ethyl ether of 4-stilbenol (MG624), a well-known α7- and α9*-nAChRs antagonist, into some selective antagonists of human α9*-nAChR. Among these, the compound with cyclohexyldimethylammonium head (7) stands out for having no α7-nAChR agonist or antagonist effect along with very low affinity at both α7- and α3β4-nAChRs. At supra-micromolar concentrations, 7 and the other selective α9* antagonists behaved as partial agonists at α9*-nAChRs with a very brief response, followed by rebound current once the application is stopped and the channel is disengaged. The small or null postapplication activity of ACh seems to be related to the slow recovery of the rebound current.

Abstract
Adenocarcinoma and glioblastoma cell lines express α7- and α9α10-containing nicotinic acetylcholine receptors (nAChRs), whose activation promotes tumor cell growth. On these cells, the triethylammoniumethyl ether of 4-stilbenol MG624, a known selective antagonist of α7 and α9α10 nAChRs, has antiproliferative activity. The structural analogy of MG624 with the mitocan RDM-4'BTPI, triphenylphosphoniumbutyl ether of pterostilbene, suggested us that molecular hybridization among their three substructures (stilbenoxy residue, alkylene linker, and terminal onium) and elongation of the alkylene linker might result in novel antitumor agents with higher potency and selectivity. We found that lengthening the ethylene bridge in the triethylammonium derivatives results in more potent and selective toxicity toward adenocarcinoma and glioblastoma cells, which was paralleled by increased α7 and α9α10 nAChR antagonism and improved ability of reducing mitochondrial ATP production. Elongation of the alkylene linker was advantageous also for the triphenylphosphonium derivatives resulting in a generalized enhancement of antitumor activity, associated with increased mitotoxicity.
