(R)-Nepicastat HCl 是一种有效的和选择性的多巴胺β-羟化酶抑制剂,(R)-Nepicastat的作用较Nepicastat弱2 ~ 3倍[1].
在比格犬与自发性高血压大鼠中,Nepicastat剂量依赖性地减少大脑皮质\左心室以及动脉中去甲肾上腺素,并增加多巴胺以及多巴胺/去甲肾上腺素比率.在比格犬中,Nepicastat(2 mg/kg)显著减少血浆中去甲肾上腺素(52%),并增加多巴胺(646%)以及多巴胺/去甲肾上腺素比率[1].在毁脊髓的自发性高血压大鼠中,Nepicastat刺激交感节前神经,以抑制升压和正性变时作用.在自发性高血压大鼠中,Nepicastat(3 mg/kg)具有降压作用并降低肾血管阻力(38%)[2].在大鼠中,Nepicastat显著增加内侧前额叶皮质中Cocaine和Amphetamine诱导的胞外多巴胺积累.
