Spinorphin 是一种内源性的脑啡肽降解酶(氨基肽酶、二肽基氨基肽酶III、血管紧张素转化酶和脑啡肽酶)抑制剂[1]。同时,Spinorphin是人P2X3 受体和N-甲酰基肽受体亚型FPR的强效拮抗剂,IC50值为8.3 pM[2][3]。
脑啡肽降解酶是水解脑啡肽的一系列酶类,在血压、疼痛、高血压和心血管疾病的管理中起重要作用。
在转染小鼠FPR的人胚肾(HEK)293细胞中, spinorphin诱导细胞内Ca2+浓度明显上升,EC50值为128 μM。同时,在正常的小鼠嗜中性粒细胞中,Spinorphin剂量依赖性地诱导钙流动。而来自fMLF 受体亚型FPR缺陷小鼠的嗜中性粒细胞无应答[ 3 ]。
在小鼠中,鞘内注射spinorphin剂量依赖性地抑制鞘内孤啡肽诱发的痛觉异常。另外, spinorphin 增强脑啡肽对孤啡肽诱发的痛觉异常的抑制作用[ 4 ]。
