Biological Activity

[Description]:

Phaclofen is a selective GABAB receptor antagonist. Phaclofen is a peripheral and central baclofen antagonist. Phaclofen maybe a potential compound in determining the physiological significance of central and peripheral bicuculline-insensitive receptors with which GABA and (-)-baclofen interact[1][2].

GABAB receptor[1]

[In Vivo]

Phaclofen (100 nmol; intrathecal injection) antagonizes the depressant effect of baclofen. Phaclofen (100 nmol) is devoid of stimulatory or depressant effects on spinal reflexes[3].

J. Neurophysiol. 112(1) , 22-9, (2014)

Transmitter-mediated homosynaptic potentiation is generally implemented by the same transmitter that mediates the excitatory postsynaptic potentials (EPSPs), e.g., glutamate. When a presynaptic neuron...
