  Synthesis and 5-hydroxytryptamine antagonist activity of 2-[[2-(dimethylamino)ethyl]thio]-3-phenylquinoline and its analogs

  摘要：

  A series of 2-[(2-aminoethyl)thio]quinolines substituted at the 3-position with alkyl, aryl, or heteroaryl groups has been prepared in the search for novel and selective 5-HT2 antagonists. The affinity of the compounds for 5-HT1 receptor sites was measured by their ability to displace [3H]-5-HT from rat brain synaptosomes whereas the affinity for 5-HT2 receptor sites was measured by their ability to displace [3H]spiperone from synaptosomes prepared from rat brain cortex. The 5-HT2 antagonist properties of the compounds were measured in vivo by their antagonism of 5-hydroxytryptophan-induced head twitches in the mouse and by their antagonism of hyperthermia induced by fenfluramine (N-ethyl-alpha-methyl-m-(trifluoromethyl)phenethylamine hydrochloride) in the rat. The structure-activity relationships in this series are discussed and the properties of 2-[[2-(dimethylamino)ethyl]thio]-3-phenylquinoline hydrochloride (70) are highlighted.

  Benzofuro[2,3-b]quinoline (Ia) and its 11-methyl derivative (Ib) were synthesized by demethylcyclization of 3-(o-methoxyphenyl)-1,2-dihydroquinolin-2-ones (VIa,b). Benzofuro[2,3-b]quinoline-11-carboxylic acid (Id) was synthesized by chlorination followed by the action of potassium hydroxide of a lactone (IX) prepared by demethyl-cyclization of 3-(o-methoxyphenyl)-2-oxo-1,2-dihydroquinoline-4-carboxylic

  通过3-（邻甲氧基苯基）-1,2-二氢喹啉-2-酮（VIa，b）的脱甲基环化反应合成苯并呋喃[2,3- b ]喹啉（Ia）及其11-甲基衍生物（Ib）。苯并呋喃[2,3 - b ]喹啉-11-羧酸（Id）通过氯化反应，然后通过3-（邻甲氧基苯基）-2-的甲基环化反应制得的内酯（IX）的氢氧化钾作用合成氧代1,2-二氢喹啉-4-羧酸（VIII）。异构苯并呋喃[3,2-c]喹啉（Ha）及其6-甲基衍生物（IIb）是通过3-（o-甲氧基苯基）-1,4-二氢喹啉-4-酮（XIa，b）。通过与苯甲醛缩合，然后氧化，将两种甲基衍生物（Ib和IIb）都转化为羧酸（Id和IId）。由此获得的苯并呋喃喹啉（Ia，b，d和IIa，b）被氧化成相应的N-氧化物（IIIa，b，d和IVa，b）。
