Stereoisomeric probes for the D1 dopamine receptor: synthesis and characterization of R-(+) and S-(-) enantiomers of 3-allyl-7,8-dihydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine and its 6-bromo analog

3-allyl-6-chloro (6-Cl-APB) analogues of SKF 38393 are reported to have higher affinity and selectivity for the D1 DA receptor and higher in vivo central neuropharmacologic activity than SKF 38393. We recently reported the corresponding 3-allyl-6-bromo analogue (6-Br-APB) also to be a high-affinity D1 agonist. We now describe the synthesis and characterization of the R-(+) and S-(-) enantiomers of both APB
取代的1-苯基-3-苯并ze庚因(例如,SKF 38393和非诺多))在对D1多巴胺受体的适度高亲和力结合和部分激动剂活化中表现出立体选择性。据报道,SKF 38393的3-烯丙基(APB)和3-烯丙基-6-氯(6-Cl-APB)类似物对D1 DA受体具有更高的亲和力和选择性,并且在体内中枢神经药理活性高于SKF 38393我们最近报道了相应的3-烯丙基6-溴类似物(6-Br-APB)也是高亲和力的D1激动剂。现在,我们描述APB和6-Br-APB的R-(+)和S-(-)对映体的合成和表征,以及与D1受体结合亲和力和D1和D2的SKF 38393对应对映体的比较选择性。两种新型取代的1-苯基-3-苯并ze庚因的R-(+)对映体均以比其S-(-)对映体高得多的亲和力和选择性与大鼠前脑组织中的D1受体位点结合。R-(+)-3-烯丙基-6-溴-7,8-二羟基-1-苯基-2,3,4,5-四氢-1H-3-苯并ze
