A compound of the formula:
R1 and R2 are independently C1-C4 alkyl; or R1 and R2, taken together with the carbon atom to which they are attached, form a mono-, bi-, tri- or spiro-cyclic group having 3 to 13 carbon atoms, wherein the cyclic group is optionally substituted by one to five substituents; A is (C1-C3)alkyl, phenyl, benzyl or the like; R is hydrogen, (C1-C3)alkyl, amino-(C1-C6)alkyl, heterocyclic-(C1-C3)alkyl wherein the heterocyclic is optionally substituted by amino, ((C1-C4)alkyl)-Z-(C1-C6)alkyl wherein Z is OC(=O) or the like; and X is (C1-C3)alkyl, phenyl or the like. These compounds are useful as ORL1-receptor agonists, and useful as analgesics or the like in mammalian subjects.
式中的化合物:
R1 和 R2 独立地为 C1-C4 烷基;或 R1 和 R2 与它们所连接的碳原子一起,形成具有 3 至 13 个碳原子的单环、双环、三环或螺环基团,其中环基团任选被 1 至 5 个取代基取代;A是(C1-C3)烷基、苯基、苄基或类似物;R是氢、(C1-C3)烷基、氨基-(C1-C6)烷基、杂环-(C1-C3)烷基(其中杂环任选被氨基取代)、((C1-C4)烷基)-Z-(C1-C6)烷基(其中 Z 是 OC(=O) 或类似物);X是(C1-C3)烷基、苯基或类似物。这些化合物可用作 ORL1 受体激动剂,也可用作哺乳动物的镇痛剂或类似药物。
