Biochem/physiol Actions

4BP-TQS is an atypical agonist of a7-nAChR that binds to the receptor in an intrasubunit cavity, and activates the channel via a mechanism that is distinct from conventional agonists. Maximal activation of a7-nAChR by 4BP-TQS is eight fold greater than activation by a maximum dose of acetylcholine (Ach), and 4BP-TQS can poteniate an EC10 concentration of ACh to invoke a response that is 540-fold higher than the maximal dose of ACh alone.
