Patent ID: 7037922

Claim:
A compound of the formula: or pharmaceutically acceptable non-toxic salts or pharmaceutically acceptable solvates thereof wherein: Y is hydrogen, straight or branched chain lower alkyl having 1–6 carbon atoms, halogen, amino, hydroxyl, or lower alkoxy having 1–6 carbon atoms; or Y is straight or branched chain lower alkyl having 1–6 carbon atoms or lower alkoxy having 1–6 carbon atoms each of which is substituted on the alkyl chain with an amino or mono or dialkylamino group where each alkyl is independently lower alkyl; W is phenyl, thienyl, or pyridyl, each of which may be mono or disubstituted with halogen, cyano, trifluoromethyl, trifluoromethoxy, hydroxy, straight or branched chain lower alkyl having 1–6 carbon atoms, straight or branched chain lower alkoxy having 1–6 carbon atoms, amino, or mono or dialkylamino where each alkyl is straight or branched chain lower alkyl having 1–6 carbon atoms; wherein: A represents C—R 1 ; B represents C—R 2 ; C represents C—R 3 ; D represents nitrogen; R 1 through R 3 are the same or different and represent hydrogen, halogen, cyano, trifluoromethyl, trifluoromethoxy, hydroxy, straight or branched chain lower alkyl having 1–6 carbon atoms, amino, mono or dialkylamino where each alkyl is straight or branched chain lower alkyl having 1–6 carbon atoms, or straight or branched chain lower alkoxy having 1–6 carbon atoms: X is dihydroimidazolyl, —CONR 6 R 7 , or —NR 7 COR 6 , where R 6 is (C 3 –C 6 )cycloalkyl(C 1 –C 6 )alkyl, alkyl substituted with optionally substituted phenyl, or cycloalkyl fused to phenyl; R 7 represents hydrogen or straight or branched chain lower alkyl having 1–6 carbon atoms; or R 6 and R 7 together form a 6-membered ring fused to a benzene to form a tetrahydroisoquinoline group.
