9 N-alkylated derivatives of dextromethorphan are synthesized and studied as non-competitive inhibitors of α3β4 nicotinic acetylcholine receptors (nAChRs). In vitro activity towards α3β4 nicotinic acetylcholine receptor is determined using a patch-clamp technique and is in the micromolar range. Homology modeling, molecular docking and molecular dynamics of ligand-receptor complexes in POPC membrane
合成并研究了9种右美沙芬的N-烷基化衍生物,作为α3β4烟碱型乙酰胆碱受体(nAChRs)的非竞争性抑制剂。使用膜片钳技术测定对α3β4烟碱乙酰胆碱受体的体外活性,其活性在微摩尔范围内。利用POPC膜上的配体-受体配合物的同源性建模,分子对接和分子动力学,寻找N-烷基化右美沙芬衍生物与α3β4nAChR的相互作用方式。该化合物与右美沙芬相似,与α3β4nAChR离子通道的中间部分相互作用。最后,行为测试证实了所研究化合物在成瘾治疗中的潜在应用。
