General description

Gaboxadol, also referred to as 4,5,6,7-tetrahydroisoxazolo(5,4-c)pyridin-3-ol (THIP), is a GABA site agonist. It has great affinity to the δ subunit of extrasynaptic high-affinity GABAA receptors. Gaboxadol was first developed for the treatment of schizophrenia, epilepsy, primary insomnia and Huntington′s disease. It can easily cross the blood-brain barrier and is rapidly absorbed by the body.

Application

Gaboxadol hydrochloride has been used in cell migration and invasion assay to assess liver cancer cell migration.

Biochem/physiol Actions

GABAA receptor agonist.

We have made use of the δ subunit-selective allosteric modulator DS2 (4-chloro-N-[2-(2-thienyl)imidazo[1,2-a]pyridine-3-yl benzamide) to assay the contribution of δ-GABAARs to tonic and phasic conductance changes in the cerebellum, thalamus and neocortex. In cerebellar granule cells, an enhancement of the tonic
