identified novel small-molecule antagonists of the PACAP type I (PAC1) receptor using docking-based in silico screening followed by in vitro/vivo pharmacological assays. In the present study, we synthesized 18 novel derivatives based on the structure of PA-9, a recently developed antagonist of the PAC1 receptor, with a view to obtain a panel of compounds with more potent antagonistic and analgesic activities
我们最近使用基于对接的计算机模拟筛选,然后进行体外/体内药理学鉴定,确定了PACAP I型(PAC1)受体的新型小分子拮抗剂。在本研究中,我们基于PA-9(一种最近开发的PAC1受体拮抗剂)的结构合成了18种新型衍生物,以期获得一组具有更强的拮抗和镇痛活性的化合物。其中,化合物3d显示出改善的拮抗活性。鞘内注射3d抑制垂体腺苷酸环化酶激活多肽(PACAP)和脊髓神经结扎诱导的机械性异常性疼痛。效果比PA-9更有效。口服给药后,化合物3d也显示出抗痛觉过敏作用。因此,
