BIBP3226三氟乙酸盐是非肽神经肽Y Y1(NPY Y1)和神经肽FF(NPFF)受体的拮抗剂,对rNPYY1、hNPFF2和rNPFF 的Ki值分别为1.1、79和108。
神经肽Y Y1受体(NPY Y1)参与探索行为和焦虑的调节。神经肽FF(NPFF)是神经递质系统的一部分,作为内源性阿片功能的神经调质发挥功能[1]。
在CHO细胞以及大鼠脊髓背角中,BIBP 3226能够特异性地与NPFF竞争结合。在转染hNPFF2受体的细胞中,BIBP 3226(10 mM)以浓度依赖的方式拮抗NPFF(10 nM)对forskolin刺激的环AMP产生的抑制[2]。
在小鼠模型中,在第三脑室注入BIBP 3226(5 nmol)完全拮抗NPFF(30 nmol)和NPVF(30 nmol)的低温效应。在小鼠甩尾试验中,BIBP 3226(5 nmol)抑制NPFF(10 nmol)的抗吗啡效果。在雄性Wistar大鼠中,5 mg的BIBP3226引起焦虑样作用,而低剂量是无效的。同时,在所有实验组中,整体运动活性没有改变[1]。而且,在尿烷麻醉的大鼠中,BIBP3226(500 nmol / kg)显著降低NPFF(200 nmol / kg)和NPVF(200 nmol / kg)诱导的平均动脉血压[3]。
