효소 저해제
These neurotoxic GABAA receptor antagonists, consisting of a nearly 1:1
mixture of picrotoxinin, (FW = 292.29 g/mol; CAS 17617-45-7) and
picrotin (FW = 310.30 g/mol; CAS 124-87-8), is a bitter-tasting (hence the
Greek prefix picros) principle, also known as cocculin, from fishberry seeds
(Anamirta cocculus) and the Philippine bayating (Tinomiscium
philippinense). Picrotoxin binds to the chloride channel of the receptor
without displacing g-aminobutyric acid. Picrotoxin is highly toxic,
exerting both stimulant and convulsant effects, and care must be exercised
when handling this agent.
