Patent ID: 7579323

Claim:
A compound or pharmaceutically acceptable salt thereof, of the formula: wherein: R 1 and R 2 are independently selected from the group consisting of: H and a saturated or unsaturated moiety having a linear, branched, or non-aromatic cyclic skeleton containing one to ten carbon atoms, and the carbon atoms are optionally substituted with: —OH, —I, —Br, —Cl, —F, —CN, —CO 2 H, —CHO, —COSH, or —NO 2 ; R 3 and R 4 are independently selected from the group consisting of: H, R, and ArR—, or R 3 and R 4 are joined to form a ring; R 5 is selected from the group consisting of: H, R, ArR—, and Ar; R 6 is selected from the group consisting of: H, R, and ArR—; R 7 and R 8 are independently selected from the group consisting of: H, R, and ArR—; and R 9 is: R is defined as a saturated or unsaturated moiety having a linear, branched, or non-aromatic cyclic skeleton containing one to ten carbon atoms, zero to four nitrogen atoms, zero to four oxygen atoms, and zero to four sulfur atoms, and the carbon atoms are optionally substituted with: ═O, ═S, —OH, —OR 10 , —O 2 CR 10 , —SH, —SR 10 , —SOCR 10 , —NH 2 , —NHR 10 , —N(R 10 ) 2 , —NHCOR 10 , —NR 10 COR 10 , —I, —Br, —Cl, —F, —CN, —CO 2 H, —CO 2 R 10 , —CHO, —COR 10 , —CONH 2 , —CONHR 10 , —CON(R 10 ) 2 , —COSH, —COSR 10 , —NO 2 , —SO 3 H, —SOR 10 , —SO 2 R 10 , wherein R 10 is a linear, branched or cyclic, one to ten carbon saturated or unsaturated alkyl group, the ring formed by joining R 3 and R 4 is a three to seven member non-aromatic cyclic skeleton within the definition of R, Ar is an aromatic ring selected from the group consisting of: phenyl, naphthyl, anthracyl, and pyrrolyl; Y is a linear, unsaturated, two to six carbon alkyl group, optionally substituted with R, ArR—, or X; provided however if R 8 is H, then the optional substituents on Y are limited to R and ArR— wherein R is linear, branched or cyclic alkyl of one to ten carbon atoms and Ar is phenyl, naphthyl, anthracyl, or phenanthryl; X is defined as a moiety selected from the group consisting of: —OH, —OR, ═O, ═S, —O 2 CR, —SH, —SR, —SOCR, —NH 2 , —NHR, —N(R) 2 , —NHCOR, —NRCOR, —I, —Br, —Cl, —F, —CN, —CO 2 H, —CO 2 R, —CHO, —COR, —CONH 2 , —CONHR, —CON(R) 2 , —COSH, —COSR, —NO 2 , —SO 3 H, —SOR, and —SO 2 R; and Z is defined as a moiety selected from the group consisting of: —OH, —OR; —SH; —SR; —NH 2 ; —NRCH(R 11 )COOH; and —NHCH(R 11 )COOH, wherein R 11 is a moiety having the formula: R, or —(CH 2 ) n NR 12 R 13 , wherein n=1-4 and R 12 and R 13 are independently selected from the group consisting of: H; R; and —C(NH)(NH 2 ), or pharmaceutically acceptable salt thereof.
