Chemical Name: 3,4-Difluoro-N-[(1S)-1-[6-[4-(2-pyridinyl)-1-piperazinyl]-2-pyrazinyl]ethyl]benzenepropanamide
Biological ActivityPositive allosteric modulator of α7 nAChRs (EC50 ~0.3 μM); active enantiomer. Increases potency of acetylcholine (EC50 values are 0.007 mM and 0.3 mM in the presence and absence of B 937B, respectively). Potentiates peak acetylcholine-induced currents 6-fold relative to maximal acetylcholine, and slows channel desensitization, resulting in a 6900-fold increase in charge transfer. Decreases paw edema in vivo. Analgesic.
