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 or a double bond as described herein; 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)n(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.
