General description

Phaclofen is a phosphonic acid derivative of baclofen.

Application

Phaclofen has been used to block GABAB receptor.

Biochem/physiol Actions

Phaclofen plays a vital role in identifying the physiological importance of central and peripheral bicuculline-insensitive receptors with which GABA and (−) baclofen interact. Phaclofen acts as a GABAB receptor antagonist. Phaclofen has an ability to reversibly block the late, bicuculline resistant, K+ dependent inhibitory postsynaptic potential (IPSP) logged in projection cells of the cat and rat dorsal lateral geniculate nucleus and in rat hippocampal CA1 pyramidal neurons.

GABA mediated neuronal system regulates hippocampus-dependent memory and stress responses by controlling plasticity and neuronal excitability. Here, we demonstrate that betaine ameliorates water-immersion restraint stress (WIRS)-induced memory impairments. This improvement was inhibited by a betaine/GABA transporter-1 (GABA transporter-2: GAT2) inhibitor

Phaclofen has recently been described as an antagonist to baclofen at both peripheral and central receptors. We have applied phaclofen in known concentrations to an isolated rat brain slice preparation containing the septal nuclei. Our data demonstrate that phaclofen antagonizes
