Activity of 7, 4, and 5 at the α7 nAChR. The vertical axis refers to the net charge of the compound at the given concentration co-applied with 10 µM 1, relative to 60 µM ACh controls. Experimental values are the average normalized response of at least four cells (± S.E.M.). In all cases these compounds showed less than 10% of the control ACh response when they were applied alone to the receptor.
