the skeletons of the orthosteric muscarinic agonists, iperoxo and isox, on the other hand, were synthesized. The two molecular moieties were connected via a polymethylene linker of varying length. These bipharmacophoric compounds were investigated for inhibition of AChE (from electric eel) and BChE (from equine serum) as well as human ChEs in vitro and compared to previously synthesized dimeric inhibitors
一组杂合化合物,其一方面由毒蕈碱受体的变构调节剂的片段(即W84和萘甲铵)与著名的AChE抑制剂他克林组成,另一方面由正构毒蕈碱激动剂的骨架,peroxox和isox组成。另一方面,是合成的。这两个分子部分通过不同长度的聚亚甲基接头连接。在体外研究了这些双药效化合物对AChE(来自鳗鱼)和BChE(来自马血清)以及人类ChEs的抑制作用,并将其与先前合成的二聚体抑制剂进行了比较。在研究的杂种中,化合物10-C10,其特点是由10个碳的亚烷基接头连接他克林和哌咯酮,被证明是最有效的抑制剂,其pIC 50值最高,为9.81(来自鳗鱼的AChE)和8.75(来自马血清的BChE)。对接用化合物实验10-C10,7B-C10,和图7a-C10有助于解释对乙酰胆碱酯酶,其通过变构分子部分的性质影响了实验的抑制力,与含他克林杂交就比活性更高的含萘二甲酰亚胺和邻苯二甲酰亚胺的类似物。此外,发现最活跃的AChE抑制剂对M
