The synthesis of a new series of Erythrina alkaloid analogues and their pharmacological characterization at various nicotine acetylcholine receptor (nAChR) subtypes are described. The compounds were designed to be simplified analogues of aromatic erythrinanes with the aim of obtaining subtype-selective antagonists for the nAChRs and thereby probe the potential of using these natural products as scaffolds
描述了一系列新的刺桐生物碱类似物的合成及其在各种烟碱乙酰胆碱受体(nAChR)亚型上的药理学表征。这些化合物被设计为芳香族赤藓醚的简化类似物,目的是获得nAChRs的亚型选择性拮抗剂,从而探索使用这些天然产物作为支架进行进一步配体优化的潜力。最有选择性和最有力的nAChR配体来自6,7-二甲氧基-2-甲基-1,2,3,4-四氢异喹啉(3c)系列(也是O的天然产物)-甲基corypalline),显示出对α4β2nAChR的亚微摩尔结合亲和力,其选择性是α4β4,α3β4和α7的300倍以上。此外,这种铅结构(对单胺氧化酶A和B以及5-羟色胺和去甲肾上腺素转运蛋白也具有抑制活性)在小鼠强迫游泳试验中以30 mg / kg的剂量表现出抗抑郁样作用。
