This invention provides compounds having the structure:
wherein each of R1, R2, R3 and R9 is independently H; straight chain or branched, substituted or unsubstituted C1-C7 alkyl, C2-C7 alkenyl or alkynyl; C3-C7 cycloalkyl or cycloalkenyl; acyl, phenyl, substituted phenyl, or heteroaryl; wherein each dashed line represents a single bond or a double bond with the proviso that if R1 is present, R3 is absent and there is a double bond between N at position 3 and C at position 2 and a single bond between C at position 2 and N at position 1 and if R3 is present, R1 is absent and there is a double bond between N at position 1 and C at position 2 and a single bond between C at position 2 and N at position 3; wherein each of R4, R5 and R6 is independently H, F, Cl, Br, I; straight chain or branched, substituted or unsubstituted C1-C7 alkyl, C2-C7 alkenyl or alkynyl; C3-C7 cycloalkyl or cycloalkenyl; phenyl, substituted phenyl, heteroaryl, —OH, —OR7, —CN, —COR7, —CO2R7, —CON(R7)2, —OCOR7, —SR7, —N(R7)2, —NR7COR7, —(CH2)nOR7, —(CH2)nN(R7)2, —(CH2)nNR7COR7, wherein n is an integer from 1 to 4; and wherein each of R7 and R8 is independently H; straight chain or branched, substituted or unsubstituted C1-C7 alkyl, C2-C7 alkenyl or alkynyl; phenyl or substituted phenyl.
These compounds are selective for cloned human alpha 2 receptors and are useful as analgesic, sedative or anaesthetic agents.
本发明提供了具有以下结构的化合物:其中R1、R2、R3和R9中的每一个独立地是H;直链或支链,取代或未取代的C1-C7烷基,C2-C7烯基或炔基;C3-C7环烷基或环烯基;酰基,苯基,取代苯基或杂环基;其中每个虚线表示单键或双键,但如果R1存在,则R3不存在,并且在位置3的N和位置2的C之间存在双键,在位置2的C和位置1的N之间存在单键,如果R3存在,则R1不存在,并且在位置1的N和位置2的C之间存在双键,在位置2的C和位置3的N之间存在单键;其中R4、R5和R6中的每一个独立地是H、F、Cl、Br、I;直链或支链,取代或未取代的C1-C7烷基,C2-C7烯基或炔基;C3-C7环烷基或环烯基;苯基,取代苯基,杂环基,—OH,—OR7,—CN,—COR7,—CO2R7,—CON(R7)2,—OCOR7,—SR7,—N(R7)2,—NR7COR7,—(CH2)nOR7,—(CH2)nN(R7)2,—(CH2)nNR7COR7,其中n是1到4的整数;其中R7和R8中的每一个独立地是H;直链或支链,取代或未取代的C1-C7烷基,C2-C7烯基或炔基;苯基或取代苯基。这些化合物选择性地作用于克隆的人类α2受体,并且可用作镇痛、镇静或麻醉剂。
