compuesto con (1aR-(1a-alfa,2a-beta,3-beta,6-beta,6a-beta,8(1aR-(1a-alfa,2a-beta,3-beta,6-beta,6a-beta,8aS*,8b-beta,9S*))-hexahidro-2a-hidroxi-9-(1-hidroxi-1-metiletil)-8b-metil--3,6-metano-8H-1,5,7-trioxaciclopenta(ij)cicloprop(a)azuleno-4,8(3H)-dio
Scope note: Mezcla de picrotoxinina y picrotina, que es un antagonista no competitivo de los receptores GABA-A que actúa como convulsionante. La picrotoxina bloquea el ionóforo de cloruro activado por el ÁCIDO GAMMA-AMINOBUTÍRICO. Aunque se utiliza más comúnmente como herramienta de investigación, se ha utilizado también como estimulante del SNC y como antídoto en intoxicaciones causadas por depresores del SNC, especialmente barbitúricos.

Scope note: A mixture of PICROTOXININ and PICROTIN that is a noncompetitive antagonist at GABA-A receptors acting as a convulsant. Picrotoxin blocks the GAMMA-AMINOBUTYRIC ACID-activated chloride ionophore. Although it is most often used as a research tool, it has been used as a CNS stimulant and an antidote in poisoning by CNS depressants, especially the barbiturates.
