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 represents a chain selected from C.sub.8-11 alkyl, C.sub.7-10 alkoxy, C.sub.8-11 alkanoyl and C.sub.7-10 alkanoyloxy wherein said chain is optionally substituted by hydroxyl, C.sub.1-4 alkyl or C.sub.1-4 alkoxy and wherein one of the intervening carbons of said chain is optionally replaced with a heteroatom selected from oxygen, nitrogen and sulfur; R.sup.2 and R.sup.3 each independently represent H or C.sub.1-3 alkyl; and R.sup.4 represents H, C.sub.1-4 alkyl, aryl or 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.
本文描述了一种具有高结合亲和力和选择性的色胺类似物,适用于5-HT1D.beta.受体,其化学式为:其中R.sup.1代表从C.sub.8-11烷基、C.sub.7-10烷氧基、C.sub.8-11烷酰基和C.sub.7-10烷酰氧基中选择的链,该链可以选择性地被羟基、C.sub.1-4烷基或C.sub.1-4烷氧基取代,并且该链的其中一个介入碳原子可以选择性地被氧、氮和硫等杂原子取代;R.sup.2和R.sup.3各自独立地代表H或C.sub.1-3烷基;R.sup.4代表H、C.sub.1-4烷基、芳基或芳基C.sub.1-4烷基;这些化合物可用作受体鉴定的试剂和基于受体的药物筛选计划,并且还可用于治疗5-HT1D配体适应症的情况,例如治疗偏头痛。
