Abstract:
PURPOSE: A pyrazolylmethylamine-piperazine derivative which is effective as a calcium ion channel modulator is provided to ensure effective activation as an T-type calcium ion channel antagonist and to use as an agent for preventing and treating brain diseases, heart diseases and pain diseases. CONSTITUTION: A pyrazolylmethylamine-peperazine derivative is denoted by chemical formula 1. A pharmaceutical composition for preventing and treating brain diseases, heart diseases or pain diseases by T-type calcium ion channel antagonism contains the pyrazolylmethylamine-peperazine derivative of chemical formula 1 or its pharmaceutically acceptable salt an active ingredient. The brain disease is epilepsy, depression, Parkison's disease, dementia or somnipathy. The heart disease is hypertension, cardiac arrhythmia, myocardial infarction, or congestive failure. The pain disease is chronic pain, acute pain, or neurogenic pain. The pyrazolylmethylamine-peperazine derivative is prepared by binding pyrazolylmethylamine compound of chemical formula 3 with piperazine acetyl halide compound of chemical formula 2.
Abstract:
A composition for blocking T-type calcium channel comprising morpholin-2-one derivatives is provided to block the T-type calcium channel in the same level as the conventional T-type calcium channel blocker, mibefradil, without side effects. A composition for blocking T-type calcium channel comprises morpholin-2-one derivatives represented by the formula(1), or pharmaceutically acceptable salts thereof, wherein R^1 and R^2 are each independently hydrogen, C1-C6 alkyl, C1-C6 cycloalkyl, or phenyl optionally substituted by halogen, nitro, hydroxyl or C1-C6 alkoxy; and R^3 and R^4 are each independently hydrogen, C1-C6 alkyl, C1-C6 thioalkyl, amino or phenyl optionally substituted by halogen, nitro, hydroxyl or C1-C6 alkoxy. The composition prevents or treats diseases caused by overexpression of T-type calcium channel including angina pectoris, hypertension, myocardiac infarction, pain and epilepsy.
