Patent ID: 7875721

Claim:
A compound according to the chemical structure I: Where X is N—R; R is H, an optionally substituted C 1 -C 6 alkyl group or an optionally substituted —C(O)—(C 1 -C 6 ) alkyl group; R 1 , R 2 and R 5 are each independently selected from H, OH, halogen (F, Br, Cl or I), a C 1 -C 6 optionally substituted carboxylic acid group, an optionally substituted O—(C 1 -C 6 )alkyl, an optionally substituted C 1 -C 6 hydrocarbyl or an optionally substituted aryl group: R 3 and R 4 together form a 5-membered optionally substituted heteroaryl or heterocyclic group; R 6 and R 7 together form a 5-membered optionally substituted carbocyclic group; R 6′ is absent, H, CH 3 or a CH 2 CH 3 group; R 7′ is absent, H, CH 3 or a CH 2 CH 3 group; R 7″ is absent; R 8′ is absent H, CH 3 or CH 2 CH 3 ; R 10 , R 11 , R 12 and R 13 are each independently H, OH, NO 2 , halogen (F, Br, Cl or I), a C 1 -C 6 optionally substituted carboxylic acid group, optionally substituted O—(C 1 -C 6 )alkyl, optionally substituted —C 1 -C 6 )hydrocarbyl, an optionally substituted —C(O)—(C 1 -C 6 ) alkyl, an optionally substituted —C(O)—O—(C 1 -C 6 ) alkyl, an optionally substituted O—C(O)—(C 1 -C 6 ) alkyl, or an optionally substituted —C(O)—N(C 1 -C 6 )dialkyl; R 14 together with the carbon to which R 7 is attached forms a 6-membered optionally substituted heterocyclic ring; or a stereoisomer or pharmaceutically acceptable salt thereof.
