Compositions and methods of use of gamma-ketoaldheyde scavengers for treating, preventing or improving fibrosis of the liver

A method for treating, preventing, or ameliorating liver fibrosis to a subject with or at risk of liver fibrosis, thereby inhibiting or treating the liver fibrosis, comprising the step of administering to the subject at least one compound in a dosage and amount effective to treat the dysfunction in the mammal, the compound having a structure represented by a compound of the following formula:

• wherein:
• R is N or C;
• R2 is independently H, hydroxy, halogen, nitro, CF3, C1-6 alkyl, C1-6 alkoxy, C3-10 cycloalkyl, C3-8 membered ring containing C, O, S or N, optionally substituted with one or more R2, R3 and R4, and may cyclize with to one or more R2, R3, or R5 to form an optionally substituted C3-8 membered ring containing C, O, S or N;
• R3 is H, hydroxy, halogen, nitro, CF3, C1-6 alkyl, C1-6 alkoxy, C3-10 cycloalkyl, C3-8 membered ring containing C, O, S or N, optionally substituted with one or more R4, R2 and R3 may cyclize with to one or more R2 or R5 to form an optionally substituted C3-8 membered ring containing C, O, S or N;
• R4 is H, hydroxy, halogen, nitro, CF3, C1-6 alkyl, C1-6 alkoxy, C3-10 cycloalkyl, C3-8 membered ring containing C, O, S or N, optionally substituted with one or more R4, R2 and R3 may cyclize with to one or more R2, R3, or R5 to form an optionally substituted C3-8 membered ring containing C, O, S or N;
• R5 is a bond, H, hydroxy, halogen, nitro, CF3, C1-6 alkyl, C1-6 alkoxy, C3-10 cycloalkyl, C3-8 membered ring containing C, O, S or N, optionally substituted with one or more R4, R2 and R3 may cyclize with to one or more R2, R3, or R4 to form an optionally substituted C3-8 membered ring containing C, O, S or N;
• and stereoisomers and analogs thereof;
• with a drug having a known side effect of treating, preventing, or ameliorating liver fibrosis.
