生物活性

Enciprazine dihydrochloride is an orally active non-benzodiazepine anxiolytic. Enciprazine dihydrochloride acts as an agonist of 5-HT1A receptor (5-HT1AR) and an antagonist of α1-adrenergic receptor (α1-adrenergic receptor) . Enciprazine dihydrochloride induces drug-related electroencephalogram changes by reducing the average power of δ waves and θ waves, and increasing the average power of α waves and fast β waves. Enciprazine dihydrochloride exhibits anti-aggressive activity, with only weak sedative and ataxic effects. Enciprazine dihydrochloride regulates plasma corticosterone levels and activates the hypothalamic-pituitary-adrenal axis. Enciprazine dihydrochloride can be used in research related to anxiety disorders, generalized anxiety syndrome and psychosis[1][2][3].

体内研究
(In Vivo)

Enciprazine (口服) dihydrochloride 在雄性小鼠中表现出抗攻击抗焦虑活性,在电休克诱导打斗试验中的口服 ED50 为 1.4 mg/kg[1]
Enciprazine (0.3-1.25 mg/kg;腹腔注射;单次给药) dihydrochloride 可使雌性大鼠在高架十字迷宫实验中在开放臂停留的时间轻度延长,最高可达 32%;而在高架放射臂迷宫实验中,1.5 至 20 mg/kg 的口服剂量未观察到活性[1]
Enciprazine (口服) dihydrochloride 在小鼠中表现出共济失调镇静作用,口服 ED50 为 120 mg/kg,相较于其抗焦虑抗攻击活性,治疗指数为 86[1]
Enciprazine (口服) dihydrochloride 可增强小鼠中己巴比妥诱导的镇静作用,其口服 ED50 为 46.4 mg/kg,相对于其抗焦虑抗攻击活性,治疗指数达 33[1]
Enciprazine (口服) dihydrochloride 可增强乙醇诱导的小鼠镇静作用,其口服 ED50 为 45.5 mg/kg,相较于其抗焦虑抗攻击活性,治疗指数为 32.5[1]
Enciprazine (25-50 mg/kg;口服;每日 2 次;每周给药 6 天,持续 45 天) dihydrochloride 在大鼠中每日口服剂量高达 2 × 50 mg/kg 时,未表现出躯体依赖性倾向,这一点可由长期给药 45 天后未出现戒断症状得到证实[1]
Enciprazine (5 mg/kg;腹腔注射;单次给药) dihydrochloride 可在自由活动的雄性 Sprague-Dawley 大鼠中诱导具有统计学意义、时间依赖性的脑电图 (EEG) 变化,表现为 δ 波和 θ 波活动减弱,α 波和 β2 波活动增强,且注射后 30-45 分钟达到作用峰值[2]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
