Abstract

A series of 3,5-disubtituted pyridin-2(1)-ones was synthesized. As part of a structure-activity relationship study performed in this series, structural modifications were based on 3-(indol-4-yl)-5-(pyridin-4-ylamino)pyridin-2(1)-one B, which exhibited a potent anti-allodynic effect in a rat model of inflammatory pain. In this study, new compounds were assessed for their ability to inhibit cutaneous mechanical allodynia in rats by using the capsaicin pain model. Compound 36, a 2-methoxypyridine derivative, yielded the most promising outcome, demonstrating an enhanced analgesic effect.

摘要

合成了一系列3,5-二取代吡啶-2(1)-酮。作为对该系列进行的构效关系研究的一部分,结构修饰基于3-(吲哚-4-基)-5-(吡啶-4-基氨基)吡啶-2(1)-酮B,其在炎性疼痛大鼠模型中表现出强效的抗痛觉过敏作用。在本研究中,通过使用辣椒素疼痛模型评估了新化合物抑制大鼠皮肤机械性痛觉过敏的能力。化合物36,一种2-甲氧基吡啶衍生物,产生了最有前景的结果,显示出增强的镇痛效果。
