Abstract:
PURPOSE: A novel pyrazoloimidazole compound is provided to suppress various protein kinase causing abnormal cell growth disorders. CONSTITUTION: A pyrazoloimidazole compound is denoted by chemical formula 1. A method for preparing the pyrazoloimidazole compound comprises: a step of performing cyclization and nitrosation of compounds of chemical formulas 2 and 3 to obtain a compound of chemical formula 4; a step of reducing the compound of chemical formula 4 to obtain a compound of chemical formula 5; a step of condensing the compound of chemical formula 5 with carboxylic acid compound of chemical formula 6 to obtain a compound of chemical formula 7; a step of reducing the compound of chemical formula 7 to obtain a compound of chemical formula 1a. A pharmaceutical composition for preventing and treating abnormal cell growth contains pyrazoloimidazole compounds of chemical formula 1 and pharmaceutically acceptable salt as an active ingredient.
