常見問題列表

生物活性
Lesopitron dihydrochloride 是選擇性的 5-HT1A 受體激動劑,作用于大鼠海馬膜,IC50 為 125 nM。
靶點(diǎn)

5-HT 1A Receptor

125 nM (IC 50 , in rat hippocampal membranes)

體外研究

In vitro binding and autoradiographic studies with [ 3 H]8-OH-DPAT and [ 3 H]Lesopitron as radioligands confirm that Lesopitron binds to 5-HT 1A receptors in the rat brain with a relatively high affinity (pK i =7.35). As expected of a full agonist at postsynaptic 5-HT 1A receptors, Lesopitron (IC 50 =125 nM) inhibits forskolin-stimulated adenylate cyclase activity in rat hippocampal membranes to the same extent as 5-HT. Lesopitron inhibits the firing of serotoninergic neurons both in vitro (in brainstem slices, IC 50 =120 nM).

體內(nèi)研究

Lesopitron inhibits the firing of serotoninergic neurons both in vivo (in chloral hydrate-anaesthetized rats, ID 50 =35 μg/kg i.v.). Lesopitron administered at a dose which induces anxiolytic behaviour in rats (30 μg/kg, i.p.) markedly reduces 5-HT levels (to 45% of the basal value) in cortical perfusates.
