Application

CGP52432 has been used as a γ-aminobutyric acid B (GABAB) antagonist:
  • to study its effects on the simulation of the onset of status epilepticus (SE) in mice
  • for voltage-clamp recording in mice neurons
  • to study its effects on the GABAB receptor-mediated neurotransmission in guinea pig hippocampus

Biochem/physiol Actions

CGP52432 is a very potent antagonist of GABAB receptors. (IC50 = 85 nM).
CGP52432 participates in inhibiting the glycine overflow in the hippocampus.

GABA(B) receptors mediate inhibition of neurotransmitter exocytosis from nerve endings. Unexpectedly, the well known GABA(B) receptor antagonist CGP35348 and, in part, the compound CGP52432, are now found to inhibit on their own the K(+)-evoked exocytosis of glycine when added at

Gamma-aminobutyric acid (GABA) is one of the most important neurotransmitters that regulate the excitability of GnRH neurons. Numerous studies have shown that GABA activates Cl(-) currents in GnRH neurons, and these effects are antagonized by GABA(A) receptor antagonists. The GABA(B)

Enhanced renal sympathetic nerve activity during ischemic period and the renal venous norepinephrine overflow after reperfusion play important roles in the development of ischemic acute kidney injury. We investigated the effect of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter mainly in
