Application

1(S),9(R)-(-)-Bicuculline methbromide has been used:
  • as a γ-aminobutyric acid (GABAA) receptor A antagonist: in cortical neuron culture
  • in artificial cerebrospinal fluid (ACSF) formature dentate granule neurons
  • in hypothalamic explant cultures

Actions biochimiques/physiologiques

1(S),9(R)-(−)-Bicuculline methbromide is a GABAA receptor antagonist, which blocks Ca2+-activated potassium (SK) channels. It is the water-soluble derivative of (+)-bicuculline.
