Positive allosteric modulators (PAMs) of nicotinic acetylcholine receptors (nAChR) are important therapeutic candidates as well as valuable research tools. We identified a novel type II PAM, (R)-7-bromo-N-(piperidin-3-yl)benzo[b]thiophene-2-carboxamide (Br-PBTC), which both increases activation and reactivates desensitized nAChRs. This compound increases acetylcholine-evoked responses of α2* and α4* nAChRs, but is without effect on α3* or α6* nAChRs ("*" indicates presence of other nAChR subunits). Br-BPTC binds to the C-terminal extracellular sequences of a4 subunits, which is also a PAM site for steroid hormone estrogens such as 17-β estradiol. Br-PBTC is much more potent than estrogens. Like 17-P-estradiol, the non-steroid Br-PBTC only requires one α4 subunit to potentiate nAChR function, and its potentiation is stronger with more a4 subunits. This feature enables Br-BPTC to potentiate activation of (α4β2)(α6β2)β3 but not (α6β2)2β3 nAChRs. Various bioactive analogs of Br-PBTC are provided.
