important in the modulation of tonic pain sensitivity. We report the synthesis and properties of a small library of peptidic agonists based on the active neurotensin fragment NT(8–13). Two tetrahydrofuran amino acid derivatives were synthesized to replace Tyr11 in NT(8–13). Additionally, Arg8, Arg9, and Ile12 of the lead peptide were exchanged by Lys, Lys, and Gly, respectively. The new compounds showed
NTS2神经降压素受体的刺激引起抗精神病作用,并导致非阿片类阿片类抗伤害感受的促进,这在调节补剂疼痛敏感性中很重要。我们报告了基于活性神经降压素片段NT(8-13)的小肽激动剂文库的合成和性质。合成了两个四氢呋喃氨基酸衍生物来取代NT(8-13)中的Tyr 11。另外,先导肽的Arg 8,Arg 9和Ile 12分别被Lys,Lys和Gly交换。新化合物显示出显着的NTS2结合亲和力,选择性是NTS1的1000倍。最高选择性(K i(NTS2):29 nM,K对于肽类似物17 R反式观察到i(NTS1):35,000 nM)。
