Abstract:
PURPOSE: A urea derivative is provided to selectively suppress the action of mPTP in the brain, thereby being used as a neuroprotective agent which improves the action of the mitochondria. CONSTITUTION: A urea derivative is denoted by chemical formula 1. A method for preparing the urea derivative comprises the steps of making a compound of chemical formula 2 react with isocyanate compounds or isothiocyanate compounds. The compound of chemical formula 2 is prepared by making a compound of chemical formula 3 react with benzyl halide compounds. A pharmaceutical composition for suppressing the action of mPTP contains the urea derivative or a pharmaceutically acceptable salt thereof as an active ingredient. A pharmaceutical composition for treating nervous diseases contains the urea derivative or a pharmaceutically acceptable salt thereof as an active ingredient.
Abstract:
PURPOSE: A biphenyl derivative or a pharmaceutically acceptable salt thereof is provided to ensure excellent activity to 5-HT7 serotonin receptor and to be used as a preventive and therapeutic agent for depression, migraine, anxiety, pain especially inflammatory pain and neuropathy pain, bio rhythm, sleep, smooth muscle related diseases. CONSTITUTION: A biphenyl derivative is denoted by chemical formula 2. The biphenyl derivative has a structure of chemical formula 4 or 5. A pharmaceutical composition for preventing or treating diseases contains the biphenyl derivative or a pharmaceutically acceptable salt thereof. A method for preparing the biphenyl derivative of chemical formula 2 comprises: a step of performing Suzuki coupling of aryl boronic acid of chemical formula 6 and bromobenzene aldehyde of chemical formula 7 to prepare a biphenyl aldehyde intermediate of chemical formula 8; and a step of performing reductive amination of the biphenyl aldehyde intermediate with arylpiperazine of chemical formula 9.
