PHACLOFEN Chemical Properties,Usage,Production

Uses

Phaclofen is a selective GABAB?receptor antagonist.

General Description

Phaclofen is a phosphonic acid derivative of baclofen.

Biological Activity

Selective GABA B antagonist. Phosphono analog of GABA B agonist baclofen ((RS)-4-Amino-3-(4-chlorophenyl)butanoic acid ).

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.
