Inoue H, Yoshida T, Kishi T: Determination of muscimol
and ibotenic acid
According to literature, GABA[sub]AR selective agonist muscimol
(MUS) can inhibit NMDAR-induced neurotoxicity in primary cell cultures,[sup] it can also reduce cell death in global or focal cerebral ischemia.
After ketamine microinfusion with or without muscimol
, the rodents underwent behavioral testing to assess the degree of depression or anxiety they displayed in situations of stress.

Son importantes intermediarios sinteticos ya que se pueden considerar como aminoalcoholes enmascarados, los cuales hacen parte de una amplia variedad de compuestos biologicamente activos, tales como el acido ibotenico, el muscimol
y la acivicina; asimismo tras algunas transformaciones simples pueden dar origen a iminas ciclicas, lactamas, [beta]-hidroxicetonas, nitrilos y cetonas [alfa], [beta]-insaturadas (6).

Two primary compounds, ibotenic acid and muscimol
, are known to occur in pharmacologically active levels and are partially, if not entirely, responsible for Amanita muscaria's psychoactive effects.
The researchers used the GABAergic modulators picrotoxin and mucimol to test the sleep promoting effects of withania and found that the herb's root extract induced sleep promoting effects by involving GABAergic modulation, which was antagonised by picrotoxin but potentiated by muscimol
A] agonist muscimol
to preferentially activate an inward current, while baclofen had a weak or variable response.
In the same experiments, however, injections of muscimol
(a GABA agonist) in the posterior hypothalamus transiently recovered sleep, suggesting that the sleep-promoting role of the anterior hypothalamus is dependent on inhibition of posterior hypothalamic histaminergic awakening neurons.
