Quisqualamine is the α-decarboxylated analogue of the glutamate receptor agonist and neurotoxin quisqualic acid and an analogue of the neurotransmitter γ-aminobutyric acid (GABA).
α-Decarboxylation of excitatory amino acids can produce derivatives with inhibitory effects. Relatedly, unlike quisqualic acid, quisqualamine has central depressant and neuroprotective effects, and appears to act predominantly as an agonist of the GABAA receptor and to a lesser extent as an agonist of the glycine receptor. Its actions are inhibited by GABAA receptor antagonists like bicuculline and picrotoxin and by the glycine receptor antagonist strychnine in vitro.
