Doxepin 是作为三环类抗抑郁药，可抑制血清素和去甲肾上腺素的再摄取。Doxepin 对特应性皮炎、慢性荨麻疹有治疗作用，能改善认知过程，保护中枢神经系统。Doxepin 也被认为是抗氧化应激的保护因子。

Doxepin inhibits reuptake of serotonin and norepinephrine as a tricyclic antidepressant. Doxepin has therapeutic effects in atopic dermatitis，chronic urticarial，can improve cognitive processes， protect central nervous system. Doxepin has also been proposed as a protective factor against oxidative stress [1] [2] [3].

The protective effect of doxepin is associated with the enhancement of PSD-95 and synapsin 1 expression via PI3K/AKT/mTOR signaling pathway [4]. Western Blot Analysis [4] Cell Line: SH-SY5Y human neuroblastoma cell line Concentration: 10 ng/mL Incubation Time: 2 h Result: Improved the protein expre-ssion levels of PSD-95, synapsin 1 and p-AKT in SH-SY5Y cells, and decreased the protein expression level of p-mTOR in SH-SY5Y cells.

Doxepin (intraperitoneal injection of 1 mg/kg and 5 mg/kg doxepin once a day for 21 days) can protect against the Aβ1-42-induced memory impairment in rats [4]. Animal Model: SD male rats [4] Dosage: 1, 5mg/kg Administration: Doxepin (intraperitoneal injection of 1 mg/kg and 5 mg/kg doxepin once a day for 21 days) Result: Improved the protein expression levels of PSD-95 and synapsin 1 in hippocampus and tem-poral lobe, and decreased the protein expression level of p-AKT in hippocampus and temporal lobe after treatment of 1 mg/kg of doxepin.
