Biochem/physiol Actions

SR 57227A is a highly selective of central and peripheral 5-HT3 receptors and an inhibitor of NMDA receptor-mediated responses in rat cortical pyramidal cells. It exhibits anti-depressant like effects in rats and decreased isolation-induced aggressive behavior.
Potent and selective 5-HT3 serotonin receptor agonist.

We have investigated the effect of SR 57227A, a selective 5-HT3 receptor agonist which crosses the blood brain barrier, on three rodent models in which antidepressants are active. In the forced swimming test, SR 57227A dose-dependently reduced the duration of...

The serotonin 5-HT(3) receptor is the only ligand-gated ion channel activated by serotonin and is expressed by GABAergic interneurons in many brain regions, including the cortex, amygdala and hippocampus. Furthermore, 5-HT(3) receptors are expressed by glutamatergic Cajal-Retzius cells in the...

The techniques of intracellular recording and single-electrode voltage-clamp were used to study the effect of serotonin (5-HT) and the selective 5-HT3 receptor agonist SR 57227A on N-methyl-D-aspartic acid (NMDA)-evoked responses in pyramidal cells of the rat medial prefrontal cortex (mPFC)...

Journal of neurophysiology, 94(5), 3397-3405 (2005-07-29)
Centrally expressed 5-HT3 receptors (5-HTR3) are well known for their role in wakefulness, cognition, and nociception. However, clear evidence of their participation in motor control is still lacking despite specific 5-HTR3 expression in hindlimb motor areas of the spinal cord...

Seizure, 19(1), 17-22 (2009-11-28)
There is some evidence that epileptic seizures could be induced or increased by 5-hydroxytryptamine (5-HT) attenuation, while augmentation of serotonin functions within the brain (e.g. by SSRIs) has been reported to be anticonvulsant. This study was performed to determine the...
