A pharmacophore model for butyrylcholinesterase (BChE) inhibitors was applied to a human cannabinoid subtype 2 receptor (hCB2R) agonist and verified it as a first‐generation lead for respective dual‐acting compounds. The design, synthesis, and pharmacological evaluation of various derivatives led to the identification of aminobenzimidazoles as second‐generation leads with micro‐ or sub‐micromolar activities
将丁酰胆碱酯酶(BChE)抑制剂的药效团模型应用于人类大麻素亚型2受体(h CB 2 R)激动剂,并验证其是相应双作用化合物的第一代先导。对各种衍生物的设计,合成和药理学评估导致鉴定出氨基苯并咪唑为第二代产品,在两个目标上均具有微或亚微摩尔活性,并且在h CB 1和AChE上具有优异的选择性。通过在活跃的h CB 2 R模型上应用分子动力学(MD)以及在h上的对接和MD来对第一代和第二代铅结构进行计算研究BChE可以解释它们在蛋白质水平上的结合情况,并为进一步优化开辟了道路。可以获得具有“平衡”亲和力和出色选择性的双作用化合物,它们代表了治疗神经退行性疾病中发生的认知和病理生理损伤的线索。
