and 5-substitution on affinity for the 5-HT1A receptor was evaluated in competition experiments using rat hippocampal membranes and [3H]8-OH-DPAT as radioligand. Selected compounds were also tested for their affinity to the D1 (rat striatum), D2 (rat striatum), D2A (human cloned), and 5-HT2A (rat cortex) receptors. The intrinsic activity of the compounds was evaluated by measuring their effect on VIP-stimulated
从(R)-和(S)-5-甲氧基-3-氨基-3,4合成了一系列新的对映体纯的3-氨基-3,4-二氢-2H-1-苯并吡喃(3-氨基苯并吡喃) -二氢-2H-1-苯并吡喃。(R)-和(S)-对映体的绝对构型由(R)-3-(N-异丙氨基)-5-甲氧基-3,4-二氢-2H-1-的X射线晶体学推论得出苯并吡喃(R)-9a。通过钯催化的N-取代的3-氨基-5-三氟甲磺酰氧基-3,4-二氢-2H-1-苯并吡喃的羰基化反应引入各种5-取代基。在大鼠海马膜和[3H] 8-OH-DPAT作为放射性配体的竞争实验中,评估了N和5取代对5-HT1A受体亲和力的影响。还测试了所选化合物对D1(大鼠纹状体),D2(大鼠纹状体),D2A(人克隆)和5-HT2A(大鼠皮层)受体的亲和力。通过测量化合物对VIP刺激的cAMP产生的作用进行评估,这些作用在被5-HT1A受体稳定转染的GH4ZD10细胞中产生。在5-位的羧酸酯,
