Inhibition of Na⁺- or Li⁺-induced inward current by CGP-37157. a Current–voltage relationships of 50 mM Na⁺-induced current in the absence (black) and presence (red) of 2 μM CGP-37157 (n = 4). b The current amplitude at −150 mV. c Current–voltage relationships of 50 mM Li⁺-induced current in the absence (black) and presence (red) of 2 μM CGP-37157 (n = 4). d The current amplitude at −150 mV. In all experiments, pipette solution contained 1 μM free Ca²⁺. *p < 0.05. CGP: CGP-37157
