Hypidone hydrochloride (YL0919) 是一种口服活性抗抑郁剂，具有双重活性，是一种高选择性的 5-HT uptake 阻滞剂和有效的 5-HT_1A receptor 激动剂 (K_i=0.19 nM)。Hypidone hydrochloride 对大鼠大脑皮层突触体和 HEK293 细胞摄取 [³H]-5-HT 有抑制作用，IC₅₀s 分别为 1.78 nM 和 1.93 nM。Hypidone hydrochloride 在动物模型中表现出明显的抗抑郁作用，对抑郁症的研究具有重要意义。

Hypidone hydrochloride (YL0919) is an orally active antidepressant agent with dual activity as a highly seletive 5-HT uptake blocker and an effective 5-HT 1A  receptor agonist (K i =0.19 nM). Hypidone hydrochloride inhibits the uptake of [H]-5-HT into rat cerebral cortical synaptosomes and HEK293 cells with IC 50 s of 1.78 nM and 1.93 nM, respectively. Hypidone hydrochloride shows remarkable antidepressant effects in animal models and has the poential for the investigation of depressive disorder.

5-HT1A Receptor

Hypidone hydrochloride inhibits the uptake of [H]-5-HT into rat cerebral cortical synaptosomes and HEK293 cells stably expressing hSERT with IC50 values of 1.78 nM and 1.93,respectively.
Hypidone hydrochloride (0.01 nM-10 μM) concentration-dependently inhibits forskolin-stimulated cAMP formation,  exerts a concentration-dependent inhibitory effect on cAMP formation with an IC50 of approximately 23.9 nM. And in antagonism studies, WAY-100635 prevents Hypidone hydrochloride-mediated inhibition of forskolin-stimulated cAMP formation.
Hypidone hydrochloride shows affinities to rat 5-HT1A receptors, SERTs, NETs, and DATs, it binds to 5-HT1A receptor, serotonin transporter (SERT) with high affinity (Ki=0.19 and 0.72 nM, respectively), but its affinity to NET and DAT are low, blocking [H]nisoxetine and [H]win35428 binding

Hypidone hydrochloride (YL0919) (oral administration; 1.25 or 5 mg/kg; 4 weeks) and fluoxetine (10 mg/kg) reverses the inhibition of locomotor activity in CUS rats.
Hypidone hydrochloride (oral administration; 1.25, 2.5, and 5 mg/kg; 4 weeks) significantly reduces the immobility time in TST in mcie FST in mice. Besides, Hypidone hydrochloride displays no effect on the locomotor activity in a separate OFT. Furthermore, the antidepressant-like effect of Hypidone hydrochloride in TST and FST is completely bunted by coadministration with WAY-100635. has not independently confirmed the accuracy of these methods. They are for reference only.
