Figure 5.
Effect of BDZ-f on the whole-cell current amplitude of the GluA2Qflop receptors obtained from the flow measurement. The inhibition constants were determined from this plot by using eq 6. KI of 3.6 ± 0.2 µM was determined for the closed-channel state (100 µM glutamate, ●); a K̅I of 5.7 ± 0.3 µM was obtained for the open-channel state (3 mM glutamate, ○).
