[Izokorin--a new blockader of gamma-aminobutyric acid receptors in the mammalian nervous system]. / Izokorin--novyi blokator retseptorov gamma-aminomaslianoi kisloty v nervnoi sisteme mlekopitaiushchikh.

Experiments on isolated neurons of sensory ganglions of rats aimed to find physiologically active plant drugs were carried out by means of voltage-clamp, intracellular perfusion and "concentration-clamp" methods. Izokorin was shown to exert blocking action on GABA-activated currents as bicuculline and korlumin. It is suggested that other bicuculline-like alkaloids corresponding to isomers can exert the same effect on GABA-activated currents.
