体外研究
(In Vitro)

Napamezole (hydrochloride) 可抑制 [3H]Clonidine 与大鼠脑 α-2 肾上腺素能受体的结合,其 Ki 为 28 nM;还可抑制 [3H]Prazosin 与大鼠脑 α-1 肾上腺素能受体的结合,其 Ki 为 93 nM[2]

体内研究
(In Vivo)

Napamezole (口服;皮下注射) 可拮抗可乐定诱导的小鼠镇痛作用,其口服给药的 ED50 为 36 mg/kg,皮下注射给药的 ED50 为 3 mg/kg,表明其具有体内 α-2 肾上腺素能受体阻断活性[1]
Napamezole (30 mg/kg;口服) 可增强大鼠脑内去甲肾上腺素的转换率,证实了其体内 α-2 肾上腺素能受体阻断活性[1]
Napamezole (≥ 1 mg/kg,静脉注射) 可增强大鼠蓝斑神经元的放电活动,还能逆转 Clonidine 对该放电活动的抑制效应,表明其具有体内 α2 肾上腺素能受体阻断活性[1]

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.
