QUINAZOLINO- AND QUINOLINO- GUANIDINES AS LIGANDS FOR THE NEUROP EPTIDE FF (NPFF) RECEPTORS

摘要

This invention provides compounds having the structure formula (I); wherein X= CH, C(CH3) or N; each of R1, R2, R3, R4 and R5 is independently H, C1-C10 straight chained or branched alkyl, C2-C10 straight chained or branched alkenyl, C2-C10 straight chained or branched alkynyl, C3-C10 cycloalkyl, substituted or unsubstituted aryl, hydroxy, halogenated ether, nitro, amino, halogen, -CN, -C(=Z)R6, -C(=Z)OR6, -C(=Z)N(R6)2' -N(R6)-C(=Z)R6, -N(R6)-C(=Z)N(R)2, -OC(=Z)R6, -C(=Z)OR6 OR6 or SR6; wherein Z is O or S; and wherein R6 is C1-C10 straight chained or branched alkyl, aryl, (CH2)nQ, C2-C10 alkenyl, C3-C10 cycloalkyl, C3-C10 cycloalkyl, c5-c10 cycloalkenyl, wherein Q is OR7, SR7, N(R7)2 or aryl, wherein R7 is H, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, wherein R2 and R3 and the carbons to which they are attached form a fused aryl, heteroaryl, C5-C10 cyclic alkyl or heterocyclic alkyl ring; or wherein R3 and R4 and the carbons to which they are attached form a fused aryl, heteroaryl, cyclic alkyl or heterocyclic alkyl ring; and wherein each alkyl, alkenyl, alkynyl and alkoxy group is optionally substituted with a substituent independently selected from Ra, where Ra is 1) hydroxy, 2) C1-C10 a1koxy, 3) halogen, 4) nitro, 5) amino, 6) CF3, or 7) carboxy, and each cycloa1kyl group is optionally substituted with a substituent independently selected from Rb, where Rb is 1) a group selected from Ra, 2) C1-C7 alkyl, 3) C2-C7 alkenyl, 4) C2-C7 alkynyl or 5) cyclic C1-C10 alkyl, and each aryl is optionally substituted with R1. This invention also provides methods of treating pain, urge incontinence; as well as methods of preparing the compounds.
