合成了一系列新的30种对称双吡啶鎓和相关的N-杂芳族双季铵盐与丙烷-1,3-二基连接基,并表征了它们在加利福尼亚鱼雷的烟碱乙酰胆碱受体(nAChR)MB327结合位点的结合亲和力。靶向此结合位点的化合物对于研究针对有机磷酸酯中毒的新型解毒剂特别感兴趣,因为其具有治疗活性,可被4-叔丁基取代的双吡啶鎓盐MB327以前被鉴定为nAChR再敏化剂。通过新开发的方法可以有效地获得目标化合物,该方法可以使具有多种官能团的空间受阻或电子失活的杂环进行N烷基化。使用最近开发的基于质谱(MS)的结合测定法测定对nAChR处MB327结合位点的结合亲和力,结果表明几种化合物的亲和力与MB327相似(p K i = 4.73±0.03)。值得注意的是,发现新制备的亲脂性4-叔丁基-3-苯基取代的双吡啶鎓盐PTM0022(3 h)具有明显更高的结合亲和力,p Ki值为5.16±0.07,代表在开发更有效的nAChR再敏化剂方面取得了可观的进步。
摘要 由3-取代的吡啶前体在无过渡金属的两步反应序列中合成了多种在4-位具有叔丁基的3,4-二取代的吡啶衍生物。在TIPS活化的吡啶中高区域选择性地添加t- Bu 2 Mg,并以硫作为氧化剂进行有效的微波辅助芳构化,以中等至极好的收率得到了所需的3,4-二取代的吡啶衍生物。该方法与3-位上存在的许多官能团如酯,酰胺,卤化物,腈或炔基兼容。 由3-取代的吡啶前体在无过渡金属的两步反应序列中合成了多种在4-位具有叔丁基的3,4-二取代的吡啶衍生物。在TIPS活化的吡啶中高区域选择性地添加t- Bu 2 Mg,并以硫作为氧化剂进行有效的微波辅助芳构化,以中等至极好的收率得到了所需的3,4-二取代的吡啶衍生物。该方法与3-位上存在的许多官能团如酯,酰胺,卤化物,腈或炔基兼容。
