Description AR-M 1896 Acetate is the selective agonist of GalR2.
In vitro 去除第 1 位的甘氨酸残基后,AR-M1896 与 GalR2 的亲和力和功能活性几乎不变,对 GalR2-Rs 的选择性是 GalR1-Rs 的 500 倍[1]。
In vivo 在正常大鼠中,通过脊髓内注射低剂量的galanin可以引起后爪的机械性和冷性痛觉过敏。与galanin等摩尔剂量的AR-M1896或AR-M961(同时作用于GalR1和GalR2受体的激动剂)也能产生同样效果。在痛觉过敏的Bennett模型大鼠中,通过脊髓内注射高剂量AR-M961后,机械阈值呈剂量依赖性增加,而在对照组或AR-M1896组中未观察到此效应。在非痛觉过敏的Bennett模型大鼠中,这两种化合物均未显示任何效果[1]。
