產(chǎn)品描述：

(–)-Stepholidine is a dopamine receptor antagonist and a partial agonist of the serotonin (5-HT) receptor subtype 5-HT1A.[1],[2],[3] (–)-Stepholidine binds to dopamine D1, D2, D3, D4, and D5 receptors (Kis = 5.1, 11.6, 24, 1,450, and 5.8 nM, respectively) as well as 5-HT1A, 5-HT2B, α2C-adrenergic receptors (α2C-ARs), and sigma-2 (σ2) receptors in a radioligand binding assay (Kis = 143, 226, 215, and 53 nM, respectively).[1] It inhibits dopamine-induced cAMP accumulation in HEK293 cells expressing dopamine D1, D2, and D5 receptors with IC50 values of 20.5, 128, and 27 nM, respectively. (–)-Stepholidine inhibits forskolin-induced cAMP production in CHO cells expressing rat 5-HT1A receptors (EC50 = 1.2 μM).[2] In vivo, (–)-stepholidine (1 mg/kg, i.v.) increases dopamine neuron firing rates, the number of spikes in bursts, and the amplitude of slow oscillations by 20, 155, and 126%, respectively, in the rat ventral tegmental area (VTA), effects that can be blocked by the 5-HT1A antagonist WAY-100635. [3] Pretreatment with (–)-stepholidine inhibits amphetamine- and phencyclidine-induced locomotor activity in rats (ED50s = 2.4 and 6.5 mg/kg, respectively).[4]
