Described herein are tryptamine analogs that display high binding affinity and selectivity for the 5-HT1D.beta. receptor, of the formula: ##STR1## wherein R.sup.1 is a group selected from aryl-C.sub.1-7 alkyl; aryl-C.sub.2-7 alkoxy; aryl-C.sub.2-7 alkanoyl and aryl-C.sub.1-7 alkanoyloxy, wherein said alkyl, alkoxy, alkanoyl and alkanoyloxy groups are optionally substituted by a C.sub.1-4 alkyl substituent and wherein said aryl group is optionally substituted by one or more substituent selected from hydroxyl, halogen, mercapto, linear or branched C.sub.1-4 alkyl, linear or branched C.sub.1-4 alkoxy, linear or branched C.sub.1-4 alkylthio, thiol substituted C.sub.1-4 alkyl and nitro substituted C.sub.1-4 alkyl; R.sup.2 and R.sup.3 are selected independently from H and C.sub.1-4 alkyl; and R.sup.4 is selected from H, C.sub.1-4 alkyl, aryl and arylC.sub.1-4 alkyl. The compounds are useful as reagents for receptor identification and in receptor-based drug screening programs, and can also be used therapeutically to treat conditions for which administration of a 5-HT1D ligand is indicated, for example in the treatment of migraine.
本文描述了一类色胺类似物,其在5-HT1D.beta.受体上表现出高结合亲和力和选择性,其化学式为:##STR1## 其中R.sup.1是从芳基-C.sub.1-7烷基;芳基-C.sub.2-7烷氧基;芳基-C.sub.2-7酰基和芳基-C.sub.1-7酰氧基中选择的基团,其中所述的烷基,烷氧基,酰基和酰氧基基团可以被C.sub.1-4烷基取代,所述的芳基基团可以被一个或多个取代基所取代,所述取代基被选择自羟基,卤素,巯基,线性或支链C.sub.1-4烷基,线性或支链C.sub.1-4烷氧基,线性或支链C.sub.1-4烷基硫基,硫醇取代的C.sub.1-4烷基和硝基取代的C.sub.1-4烷基中的一种或多种;R.sup.2和R.sup.3独立地选择自H和C.sub.1-4烷基;R.sup.4选择自H,C.sub.1-4烷基,芳基和芳基C.sub.1-4烷基。这些化合物可用作受体鉴定试剂和受体基药物筛选计划,并且也可以用于治疗需要给予5-HT1D配体的情况,例如治疗偏头痛。
