Biochem/physiol Actions

TQS is a type-II positive allosteric modulator of α7 nAChR. TQS potentiates agonist-invoked responses, and dramatically reduces the rate of desensitization of α7 nAChR. The compound has no agonist activity alone. The EC50 for potentiation of submaximal doses of acetylcholine is 6.2µM.

Conventional nicotinic acetylcholine receptor (nAChR) agonists, such as acetylcholine, act at an extracellular "orthosteric" binding site located at the interface between two adjacent subunits. Here, we present evidence of potent activation of α7 nAChRs via an allosteric transmembrane site. Previous
