Effects of chrodrimanin B on the concentration-response curve for GABA on silkworm RDL GABAR expressed in <i>Xenopus</i> oocytes.

<p>The GABA-induced responses were measured at various concentrations in the presence and absence of chrodrimanin B. The EC₅₀ value for GABA shifted from 41.1 μM (n = 4, CI = 37.3–45.2 μM) without chrodrimanin B to 143 μM (n = 4, 121–170 μM) with 3 nM chrodrimanin B and to 565 μM (n = 4, 478–668 μM) with 10 nM chrodrimanin B, respectively.
