The enantiomers of cis- and trans-1,2,3,4,4a,5,10,10a-octahydro-9-hydroxy-1- propylbenzo[g]quinolines (10 and 11, respectively) and the enantiomers of trans-1,2,3,4,4a,5,6,10b-octahydro-10- hydroxy-4-propylbenzo[f]quinoline (12) have been synthesized and their stereochemical and conformational characteristics have been studied by use of X-ray crystallography and molecular mechanics (MMP2) calculations
顺式和反式1,2,3,4,4a,5,10,10a-八氢-9-羟基-1-丙基苯并[g]喹啉的对映体(分别为10和11)以及反式对映体的对映体合成了1,2,3,4,4a,5,6,10b-八氢-10-羟基-4-丙基苯并[f]喹啉(12),并通过X射线研究了其立体化学和构象特征晶体学和分子力学(MMP2)计算。已评估了这些化合物是有效的5-羟基色胺(5-HT)受体激动剂8-羟基-2-(二丙基氨基)四氢萘(8-OH-DPAT; 1)的构象限制类似物的中心5-HT和多巴胺通过使用大鼠的生化和行为测试来刺激受体的活性。此外,我们已经评估了这些化合物和许多先前报道的类似物从5-HT1A结合位点置换[3H] -8-OH-DPAT的能力。12种对映体的作用类似于有效的5-HT1A-受体激动剂,而八氢苯并[g]喹啉衍生物的效力或惰性则低得多。通常,化合物的亲和力与它们的激动剂效力密切相关。正在研究的一组化合物由
