Muscimol

CAS 2763-96-4C4H6N2O2Heterocyclic Building Blocks

Muscimol (CAS 2763-96-4) is an isoxazole-derived bioactive small molecule with the molecular formula C4H6N2O2 and a molar mass of 114.10 g/mol. The principal psychoactive constituent of Amanita muscaria, it is a potent, selective agonist of the GABA-A receptor and a structural analogue of the neurotransmitter GABA. Tech Serve Solutions supplies muscimol as a research-grade reagent for neuroscience, receptor pharmacology and cell-biology studies. It is highly toxic and handled accordingly.

01 /Applications

GABA-A receptor research

Muscimol is a potent, selective agonist of the GABA-A receptor and is widely used as a reference pharmacological tool to probe GABAergic signalling and inhibitory neurotransmission in vitro and in tissue preparations.

Neuroscience and electrophysiology

It is employed in neuroscience studies of synaptic inhibition, ion-channel function and receptor binding, where a well-characterised GABA analogue is required as a positive control or probe.

Cell biology and pharmacology

As a bioactive small molecule, muscimol serves in cell-biology and receptor-pharmacology assays investigating GABA-A receptor subunits and downstream chloride-channel activity.

Heterocyclic building block and reference standard

The isoxazole scaffold makes muscimol useful as a heterocyclic building block in chemical synthesis and as an analytical reference standard for identification and method development.
