Strychnine
Strychnine (CAS 57-24-9, C21H22N2O2) is a highly toxic alkaloid with a molecular weight of 334.41 g/mol. It is primarily known for its potent, irreversible inhibition of glycine and GABA receptors, acting as a powerful antagonist. Historically used as a pesticide, it is now mainly employed in research settings for neuropharmacological studies and as a chiral resolving agent in asymmetric synthesis.

Neuroscience Research
Strychnine serves as a crucial tool in neuroscience to study the function of glycine and GABA receptors, key inhibitory neurotransmitter systems in the central nervous system. Researchers utilise its antagonist properties to investigate neural pathways and receptor mechanisms.
Asymmetric Synthesis
As a chiral alkaloid, strychnine and its derivatives are employed as chiral resolving agents or catalysts in stereoselective synthesis. They facilitate the separation of enantiomers or the creation of specific stereoisomers in organic chemistry.
Biochemical Probe
Its specific interaction with ion channels and neurotransmitter receptors makes strychnine a valuable biochemical probe for understanding receptor binding sites and signalling pathways.
