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.

There is only little information about the effects of GABA receptors agonist and antagonist on morphine self-administration. Present study was designed to assess role of GABAB receptors in the regulation of morphine-reinforced self-administration. THIS STUDY WAS PERFORMED IN FOUR GROUPS

The role of GABA in synaptic transmission in the mammalian central nervous system is more firmly established than for any other neurotransmitter. With virtually every neuron studied, the synaptic action of GABA is mediated by bicuculline-sensitive GABAA receptors which selectively

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

The neurotransmitter gamma-aminobutyric acid (GABA) and subtypes of GABA receptors were recently identified in adult testes. Since adult Leydig cells possess both the GABA biosynthetic enzyme glutamate decarboxylase (GAD), as well as GABA(A) and GABA(B) receptors, it is possible that

Phaclofen, the phosphonic acid derivative of baclofen, reversibly antagonized the depression of the cholinergic twitch response of the guinea pig ileum and distal colon by either baclofen or GABA. When administered microelectrophoretically, phaclofen reversibly blocked the presumed presynaptic reduction by
