产品详情
生物活性:
CGP 25454A is a selective presynaptic dopamine autoreceptor antagonist which induces the increase of dopamine and acetyl choline. CGP 25454A can be used for major depression research.

体内研究:
CGP 25454A (10-100 mg/kg, 腹腔注射, 60 min) 在大鼠纹状体中产生明显且高度依赖的 Spiperone 结合增加。CGP 25454A (0.5-100 mg/kg, 腹腔注射, 10-60 min) 在不同浓度下显示出相反的作用,在低剂量范围内具有轻微的行为刺激作用,在高剂量范围内具有明确的中枢抑制作用。Animal Model:Male Tif rats with Amphetamine-induced hyperactivity
Dosage:0.5-100 mg/kg
Administration:Intraperitoneal injection (i.p.)
Result:Did not modify ambulation but increased rearing at 2.5 and 10mg/kg, started to produce sedation at 30 mg/kg and sedation became strong at 100 mg/kg as rats were almost motionless and none of them were cataleptic.

体外研究:
CGP 25454A (0.5-10 μM, 15 min) 在大鼠纹状体切片上诱导了可重复和浓度依赖性的 DA 与 ACh 释放增加,在 10 μM 时分别增加了 62±3% 和 100±7%。CGP 25454A 与突触前DA 受体的作用比突触后的 DA 受体强 12.9 倍。
