e (BChE) and the human cannabinoid receptor 2 (hCB2R) represent promising targets for pharmacotherapy in the later stages of Alzheimer’s disease. We merged pharmacophores for both targets into small benzimidazole-based molecules, investigated SARs, and identified several dual-acting ligands with a balanced affinity/inhibitory activity and an excellent selectivity over both hCB1R and hAChE.

丁酰胆碱酯酶(BChE)和人类大麻素受体2(h CB 2 R)代表了阿尔茨海默氏病晚期药物治疗的有希望的靶点。我们将两个靶点的药效基团合并到小的苯并咪唑基分子中,研究了SAR,并鉴定了几种双作用配体,它们在h CB 1 R和h AChE上均具有平衡的亲和力/抑制活性和出色的选择性。基于h CB 1 R的晶体结构开发了h CB 2 R的同源性模型,并用于分子动力学研究以研究结合模式。体外研究证明h CB 2 R激动作用。可以设计出不需要的μ阿片受体亲和力。关于认知改善,一种平衡良好的双作用和选择性h BChE抑制剂/ h CB 2 R激动剂在体内活性方面优于铅CB 2激动剂。数据显示将小分子与选择性和平衡的GPCR活性/酶抑制作用以及体内活性结合起来治疗AD的可能性,并可能有助于合理化其他双重作用配体的开发。
