Spinorphin 是一种七肽，是一种有效的脑啡肽降解酶抑制剂。Spinorphin 抑制中型和小型培养的大鼠 DRG 神经元中由去极化和辣椒素选择性诱发的细胞质 Ca(2+) ([Ca(2+)]i) 瞬变。

Spinorphin is a heptapeptide, and is a potent enkephalin-degrading enzymes inhibitor.Spinorphin inhibited cytoplasmic Ca(2+) ([Ca(2+)]i) transients, evoked by depolarization and capsaicin selectively in medium and small cultured rat DRG neurons.?Spinorphin (10-300 M) inhibited the Ca(2+) signals in concentration dependant manner in small- and medium diameter DRG neurons.?Capsaicin produced [Ca(2+)]i responses only in small- and medium-sized DRG neurons, and pre-treatment with spinorphin significantly attenuated these [Ca(2+)]i responses.?Spinorphin significantly inhibited the functions of polymorphonuclear neutrophils (PMNs) by suppressing the binding of fMLF to its receptor on PMNs. Further, this inhibitor suppressed the carrageenan-induced accumulation of PMN in mouse air pouches after intravenous administration. These results indicate that spinorphin may be an endogenous anti-inflammatory regulator. The possible role of spinorphin and its analog as regulators in pain and inflammation will be discussed.
