2-e]isoquinolines was synthesized. The (−)-enantiomers had much greater κ-, μ-, and δ-opioid receptor binding affinity than the corresponding (+)-enantiomers. Compounds (−)-1a, (−)-1b, and (−)-1c displayed subnanomolar binding affinity for the μ-receptor, and (−)-1b had a high affinity for the κ-receptor. Compound (−)-1a was a μ-partial agonist and κ-antagonist. Compound (−)-1b was a potent neutral μ-antagonist
合成了一系列对映体N-取代的2,
3,4,4a,5,6,7,7a-八氢-1 H-
苯并呋喃[3,2- e ]
异喹啉。(-)-对映异构体比相应的(+)-对映异构体具有更大的κ-,μ-和δ-阿片样物质受体结合亲和力。化合物(-)- 1a,(-)- 1b和(-)- 1c显示出对μ受体的亚纳摩尔结合亲和力,并且(-)- 1b对κ受体具有高亲和力。化合物(-)- 1a是μ-部分激动剂和κ-拮抗剂。化合物(-)- 1b是有效的中性μ拮抗剂(K d = 0.22 nM)和κ部分激动剂。
