The neurotensin receptor subtype 2 (NTS2) is involved in the modulation of tonic pain sensitivity and psychiatric diseases and is, therefore, regarded as a highly attractive pharmacological target protein. Aiming to discover NTS2 selective ligands, we herein describe the identification of screening hits and the chemical synthesis of structural variants leading to the highly potent and NTS2 selective
神经降压素受体亚型2(NTS2)参与调节强直性疼痛敏感性和精神疾病,因此被认为是极具吸引力的药理靶蛋白。旨在发现NTS2选择性配体,我们在本文描述的筛选命中的鉴定和结构变体导致高度有效的化学合成和选择性NTS2类型的肽-类肽杂合体3的神经降压素模拟物3A和3E -克结合有ñ - (4-羟苯乙基)甘氨酸亚结构表现出一位数纳摩尔亲和力(K i= 4.3-8.8 nM)和1900-12000倍于神经降压素受体亚型1(NTS1)的选择性。根据功能实验,受试化合物3a和3e - g表现出对组成型有丝分裂原激活的蛋白激酶(MAPK)活性的抑制作用,是内源性配体神经降压素逆激动剂活性的2.6-4.6倍。
