CGP 35348 hydrate has been used as a γ-aminobutyric acid-B (GABAB) receptor inhibitor:
  • to study its effects on intrinsic optical signal (IOS) in rat hippocampus
  • alone or in combination with sodium salicylate to study its effects on auditory responses in the rat′s dorsal cortex of rat
  • to study its effects on hepatocellular carcinoma cells (HCC)


5, 25 mg in glass bottle

Biochem/physiol Actions

CGP 35348 is a γ-aminobutyric acid-B (GABAB) receptor antagonist. It has a higher affinity towards post-versus presynaptic receptors that can penetrate the blood-brain barrier.

Stress exerts profound inhibitory effects on reproductive function by suppressing the pulsatile release of gonadotrophin-releasing hormone (GnRH) and therefore luteinising hormone (LH). This effect is mediated in part via the corticotrophin-releasing factor (CRF) system, although another potential mechanism is via...

Gamma-hydroxybutyrate (GHB) is used therapeutically and recreationally. The mechanism by which GHB produces its therapeutic and recreational effects is not entirely clear, although GABA(B) receptors seem to play an important role. This role could be complex, because there are indications...

Synaptic responses resulting from stimulation of the main olfactory and vomeronasal (VN) nerves were measured in main and accessory olfactory bulb (AOB) of frog, Rana pipiens, to test the hypothesis that properties of these synapses would reflect the distinct differences...

The effects of subcutaneous (s.c.) administration of the GABA(B) receptor agonist baclofen were investigated on primary drinking in rats. Baclofen (1-4 mg/kg) produced a dose-related reduction in cumulative water intake in 16 h water-deprived rats during the 120 min measurement...

Interleukin-1beta (IL-1beta), a cytokine that is closely associated with inflammation and immune stress, is known to interfere with reproductive functions. Earlier studies have demonstrated that IL-1beta inhibits the luteinizing hormone (LH) surge during the afternoon of proestrus in female rats....
