trans-5-methoxy analogs showed selective 5-HT1A receptor activity in vitro but displayed mixed 5-HT1A and D2 agonist properties in vivo. The corresponding trans-5-hydroxy analogs were found to be potent D2 agonists with full intrinsic activity. An examination of nitrogen substitution (R2 in 3) revealed that analogs with either an allyl or an n-propyl group displayed equipotent activities. Substitution
研究了5-和8-羟基-2-(二-正丙基氨基)-四氢萘的构象受限的线性三环类似物的血清素能和多巴胺能特性。这些2,3,3a,4,9,9a-六氢-1H-苯并[f]吲哚(3)的顺式和反式类似物,其中五元环稠合在2-的氮和C-3碳之间氨基四氢萘是由5-甲氧基四氢萘酮和8-甲氧基四氢萘酮合成的。反式-5-甲氧基-Nn-丙基和-N-烯丙基类似物的对映异构体是通过对其二对甲苯甲酰基-L(或D)酒石酸盐的分步重结晶而获得的。在体外5-HT1A和D2结合试验中评估了所有类似物,并在生化和行为测试中进一步研究了所选类似物。在5取代的系列中(3中的R1),发现反式异构体比相应的顺式异构体具有更高水平的药理活性。反式-5-甲氧基类似物在体外显示选择性的5-HT1A受体活性,但在体内显示混合的5-HT1A和D2激动剂特性。发现相应的反式5-羟基类似物是具有完全内在活性的有效D2激动剂。氮取代的研究(3中的R2)表明
