Abstract:
PURPOSE: A 2-benzylsulfanyl-benzimidazole-4-carboximide derivative is provided to ensure activity of suppressing poly(ADP-ribose)polymerase-1-(PARP-1) and to prevent or treat diseases caused by over-activation of the PARP-1. CONSTITUTION: A 2-benzylsulfanyl-benzimidazole-4-carboximide derivative is denoted by chemical formula 1. The 2-benzylsulfanyl-benzimidazole-4-carboximide derivative is prepared by performing alkylation of a compound of chemical formula 2 with a compound of chemical formula 3 at room temperature to boiling point under the presence of basic catalyst. The catalyst is carbonate, hydroxise, hydride, alkoxide, triethylamine, or pyridine. A pharmaceutical composition for preventing or treating diseases caused by over-activation of poly(ADP-ribose)polymerase-1(PARP-1) contains the 2-benzylsulfanyl-benzimidazole-4-carboximide derivative of chemical formula 1 or its pharmaceutically acceptable salt as an active ingredient.
Abstract:
A novel 4-methylimidazol-5-ylcarbonylguanidine derivative is provided to show strong inhibitory activity on NHE-1, a sodium and hydrogen exchange passage, and show excellent heart protecting effect, thereby being usefully used as a therapeutic agent of ischemic heart diseases or a heat protecting agent such as a fibrinolytic enzyme. A 4-methylimidazol-5-ylcarbonylguanidine derivative represented by the formula(1) is at least one selected from the group consisting of (2-(2,3-dichlorophenyl)-4-methyl-1H-imidazol-5-ylcarbonyl)guanidine bis-methanesulfonate, (2-(2,5-dichlorophenyl)-4-methyl-1H-imidazol-5-ylcarbonyl)guanidine bis-methanesulfonate, (2-(3,5-dichlorophenyl)-4-methyl-1H-imidazol-5-ylcarbonyl)guanidine, (2-(2-methoxy-5-chlorophenyl)-4-methyl-1H-imidazol-5-ylcarbonyl)guanidine bis-methanesulfonate, and (2-(2-methoxy-5-fluorophenyl)-4-methyl-1H-imidazol-5-ylcarbonyl)guanidine bis-methanesulfonate and is prepared by reacting a carboxylic acid derivative having a leaving group(L) represented by the formula(2) with guanidine, wherein each R^1 and R^2 is independently H, halogen, trihalomethyl, mesyl, nitro, amino, C1-5 linear or branched alkyl or OR^3(wherein R^3 is H, trihalomethyl, C1-5 linear or branched alkyl or phenyl); X is H, C1-5 linear or branched alkyl or phenyl; and L is halogen, hydroxy, alkoxy, mesylate, or tosylate. A pharmaceutical composition for preventing and treating ischemic cardiac diseases comprises the 4-methylimidazol-5-ylcarbonylguanidine derivative or a pharmaceutically acceptable salt thereof as an effective ingredient.
