Description: 4BP-TQS is an allosteric agonist of α7 subunit-containing neuronal nicotinic acetylcholine receptors (nAChRs). 4BP-TQS potentiates acetylcholine-induced activation of α7 subunit-containing nAChRs by greater than 540-fold in X. laevis oocytes.1 It activates wild-type α7 subunit-containing nAChRs and nAChRs containing the α7 subunit and W148F, but not M253L, mutations in X. laevis oocytes.
