The interactions of tandospirone (formerly called SM-3997) with 5-HT and other neurotransmitter receptor binding sites were determined in brain homogenates. Tandospirone is most potent at the 5-HT1A receptor, displaying a Ki value of 27 +/- 5 nM. The agent is approximately two to three orders of magnitude less potent at 5-HT2, 5-HT1C, alpha 1-adrenergic, alpha 2-adrenergic, and dopamine D1 and D2 receptors (Ki values ranging from 1300 to 41000 nM). Tandospirone is essentially inactive at 5-HT1B… Expand
Tandospirone and its metabolite, 1-(2-pyrimidinyl)-piperazine—II. Effects of acute administration of 1-PP and long-term adminstration of tandospirone on noradrenergic neurotransmission
TLDR
It is concluded that 1-PP acts as an antagonist at somatodendritic and terminal alpha 2-adrenergic autoreceptors, as well as at postsynaptic alpha 2 -adrenoceptor agonists, in the central nervous system of the rat. Expand
Effect of tandospirone, a serotonin-1A receptor partial agonist, on information processing and locomotion in dizocilpine-treated rats
TLDR
Findings suggest that behavioural changes induced by tandospirone are not fully blocked by 5-HT1A antagonists and that tandosphereirone (5 mg/kg) potentiates the effect of MK-801, and point to an interaction between NMDA and 5- HT1A receptors. Expand
Tandospirone potentiates the fluoxetine-induced increases in extracellular dopamine via 5-HT1A receptors in the rat medial frontal cortex
TLDR
Results indicate that tandospirone potentiates the fluoxetine-induced increase in dopamine release via 5-HT(1A) receptors in the rat medial frontal cortex, and suggest that t andospir one may have therapeutic potential for the treatment of depression. Expand
Tandospirone and its metabolite, 1-(2-pyrimidinyl)-piperazine—I. Effects of acute and long-term administration of tandospirone on serotonin neurotransmission
TLDR
It is concluded that desensitization of somatodendritic 5-HT autoreceptors permits5-HT neurones to regain their physiological rate of firing during long-term treatment with tandospirone and, consequently, to release a normal amount of 5- HT into the synaptic cleft. Expand
Characterization of 5-hydroxytryptamine1A properties of flesinoxan: In Vivo electrophysiology and hypothermia study
TLDR
The flesinoxan-induced hypothermia was significantly attenuated by prior administration of the non-selective 5-HT1A antagonist pindolol and the 5- HT1/2 antagonist methysergide, suggesting that it may be an effective anxiolytic/ant antidepressant agent. Expand
In vivo drug action of tandospirone at 5-HT1A receptor examined using positron emission tomography and neuroendocrine response
TLDR
Despite the significant effect on growth hormone and body temperature, a clinical dose of tandospirone had a negligible effect on [11C]WAY 100635 binding, which indicates that the agonist produces a pharmacological effect without measurable occupancy, and a new index other than occupancy will be required for the in vivo evaluation of agonists. Expand
Tandospirone suppresses impulsive action by possible blockade of the 5-HT1A receptor.
TLDR
Tandospirone could be a therapeutic candidate for impulsivity-related disorders and may be due to the antagonistic action of the 5-HT1A receptor. Expand
Trazodone and its active metabolite m-chlorophenylpiperazine as partial agonists at 5-HT1A receptors assessed by [35S]GTPγS binding
TLDR
The agonist properties of trazodone and its active metabolite, m-chlorophenylpiperazine (m-CPP), at 5-HT1A receptors are elucidated by means of the guanosine-5′-O-(3-[ 35S]thio)-triphosphate ([35S]GTPγS) binding assay. Expand
The effects of azapirones on serotonin1A neurons of the dorsal raphe.
TLDR
The dose-response curves from buspirone and tandospirone demonstrated enough dissimilarity to the dose- response curves from gepirone and ipsapirone to suggest differences in their rates of absorption, and/or differences in the production of active and inactive metabolites. Expand
Tandospirone activates neuroendocrine and ERK (MAP kinase) signaling pathways specifically through 5-HT1A receptor mechanisms in vivo
TLDR
The results are the first evidence that systemic 5-HT1A receptor agonist administration produces a rapid increase in p-ERK levels in vivo, providing further insight into the signaling mechanisms of the 5- HT1A receptors. Expand

The results suggest that the anxiolytic effects of buspirone and TVX Q 7821 may be mediated by central 5-HT1A receptors. Expand
Interaction of SM-3997 with serotonin receptors in rat brain.

Results suggest that the action of SM-3997 may be mediated via central 5-HT1A receptors but not the BZ-GABA receptor complex. Expand

Results indicate that SM-3997 binds selectively and with high affinity to 5-HT-1A receptors in rat brain and may be an agonist. Expand

3H-PAT seems to be a useful ligand for studying the biochemical and pharmacological characteristics of presynaptic autoreceptors in selected regions of rat brain. Expand

TLDR
The concentration-response data show that the inhibition of forskolin-stimulated adenylate cyclase activity in guinea pig and rat hippocampal membranes is mediated by a receptor with the characteristics of the 5-HT1A binding site, and it is proposed that this response is suitable for measuring activities and affinities of drugs acting at 5- HT1A receptors.

The results show that SM-3997 is a new anxioselective anxiolytic agent which is weaker than buspirone in the dopaminergic neuron system. Expand
