(S)-5-Bromo-2,3-dimethoxy-N-[(1-ethyl-2-pyrrolidinyl)methyl]benzamide (6) and some related compounds, i.e. the R isomer 7, the 3-hydroxy analogue 8, the desbromo derivative 9, the monomethoxy compound 10, and the 2,4-dimethoxy analogue 11, have been synthesized from the corresponding benzoic acids. The benzamides, lacking o-hydroxy groups, were evaluated for their affinity for the [3H]spiperone binding
(S)-5-溴-2,3-二甲氧基-N-[(1-乙基-2-吡咯烷基)甲基]苯甲酰胺(6)和一些相关化合物,即R异构体7、3-羟基类似物8,由相应的苯甲酸合成去溴衍生物9,单甲氧基化合物10和2,4-二甲氧基类似物11。评估缺少邻羟基的苯甲酰胺对[3H] spiperone结合位点的亲和力,以及与相应水杨酰胺作用有关的对阿扑吗啡诱导的行为反应的抑制作用。除了2-羟基-3-甲氧基苯甲酰胺12和相关的1,4-苯并二恶烷(13)和2,3-二氢苯并呋喃(14)外,还研究了羧酰胺,以评估受体对2-甲氧基的立体电子要求相互作用。该研究支持以下观点:邻甲氧基可以采用共面和垂直方向,并维持生物活性构象中所需的分子内氢键。在体外和体内,均发现苯甲酰胺6与类似的高活性水杨酰胺3(FLB 463)等价。另外,6显示出对行为综合症的多动成分的优先抑制,这被认为表明在抗精神病有效剂量下,人诱发锥体束外副作用的趋势较
