本文比较了神经降压素(NT)和鸡肽[Lys 8,Asn 9]神经降压素-(8-13)(LANT-6)的生物学特性:(1)竞争性抑制[~ 3 H]NT与大鼠脑突触膜的结合;(2)舒张大鼠回肠;数据显示,LANT-6与NT受体相互作用,像具有完全内在活性和低亲和力的弱激动剂。LANT-6不太可能代表NT受体的生理激活剂。
The biological properties of neurotensin (NT) and the chicken peptide [Lys8,Asn9]neurotensin-(8–13) (LANT-6) were compared in 3 in vitro assays: (1) competitive inhibition of [3H]NT binding to rat brain synaptic membranes, (2) relaxation of the rat ileum, and (3) contraction of the guinea-pig ileum. The data show that LANT-6 interacted with NT receptors like a weak agonist having full intrinsic activity and low affinity. LANT-6 is unlikely to represent a physiological activator of NT receptors.
