Potentiation of acetylcholine responses by allosteric modulators on M260L α7 nAChRs. Representative traces are shown illustrating responses to acetylcholine (100 μM) (left) together with responses from the same oocyte after pre- and co-application of an allosteric modulator (10 μM) (right). Representative traces are shown for NS-1738 (A), TQS (B), TBS-346 (C), TBS-546 (D), TBS-345 (E), TBS-556 (F) and TBS-516 (G).
