produce adverse effects in vivo. Herein we present the synthesis and pharmacological evaluation of a series of pyrrole-3-carboxamides with a diverse range of allosteric profiles. We proposed structural modifications at top, core, or pendant moieties of a prototypical molecule. Although generally there was a correlation between the degree of agonist activity and the modulatory potency of the PAMs, some derivatives
定位于M 1的变构位点毒蕈碱型乙酰胆碱受体是一种治疗阿尔茨海默氏病的有前途的策略。正变构调节剂不仅可以增强内源性激动剂乙酰胆碱(ACh)的结合和/或信号传导,而且还可以具有直接激动剂活性(因此称为PAM激动剂)。最近的研究表明,具有强大内在功效的PAM激动剂更可能在体内产生不良反应。本文中,我们介绍了一系列具有多种变构特征的吡咯-3-羧酰胺的合成和药理学评价。我们提议在原型分子的顶部,核心或侧基部分进行结构修饰。尽管通常激动剂活性的程度与PAM的调节效能之间存在相关性,一些衍生物显示出较弱的内在功效,但仍保持强的变构调节作用。我们还确定了具有主要增强ACh亲和力或亲和力和功效的能力的分子。
