Galantide 是一种特殊的甘丙肽受体 (galanin receptor) 拮抗剂,是一种由甘丙肽和P物质片段组成的肽段,在大鼠下丘脑可识别两类甘丙肽结合位点 (KD 分别小于 0.1 nM 和 ~6 nM)。Galantide 剂量依赖性 (IC50=1.0 nM) 拮抗甘丙肽介导的葡萄糖诱导的小鼠胰岛胰岛素分泌抑制。Galantide 似乎与单一的 SP 受体群结合 (KD~40 nM)。
Galantide do not activate the K+ conductance but produces a concentration-dependent antagonism (IC50=4 nM) of the galanin-induced increase in K+ conductance. Galantide acts like galanin and inhibits the voltage-dependent Ba2+ current (IBa). The inhibition of IBa also is concentration dependent (IC50=16 nM) and the maximum inhibition produced by galantide is approximately 40%[3].
