Abstract:
PURPOSE: A phenoxypropanol derivative is provided to effectively suppress T-type calcium channel or TWIK-related K+ (TREK)-1 channel, thereby treating various diseases caused by the activation of the channels. CONSTITUTION: A phenoxypropanol derivative of chemical formula I or a racemic body, a pharmaceutically acceptable salt, a solvate, or a hydrate thereof is provided. A pharmaceutical composition for preventing or treating diseases related to T-type calcium channel or TREK-1 channel, selected among Parkinson's disease, Alzheimer's disease, schizophrenia, sleep disorder, epilepsy, pain, hypertension, arrhythmia, ventricular hypertrophy, angina pectoris, heart failure, myocardial infarction, cancer, hypoxia, cerebral ischemia, alkalemia, and depression contains the phenoxypropanol derivative, the racemic body, the pharmaceutically acceptable salt, the solvate, or the hydrate as an active ingredient. A method for suppressing T-type calcium channel or TREK-1 channel comprises the steps of: preparing a biological sample from an organ; and applying the phenoxypropanol derivative, the racemic body, the pharmaceutically acceptable salt, the solvate, or the hydrate to the biological sample.

Abstract:
PURPOSE: Provided is a method for producing (alkoxy polyoxyalkylene glycol)alkyl unsaturated carboxylic acid diester compounds which have excellent thermal stability and shelf stability and thus are useful for starting materials of concrete admixture. CONSTITUTION: The method for producing an (alkoxy polyoxyalkylene glycol)alkyl unsaturated carboxylic acid diester compound represented by the following formula 1 comprises carrying out transesterification of a dialkyl ester of unsaturated dicarboxylic acid containing at least one double bond, represented by the following formula 2 with a (polyoxyalkyleneglycol)alkyl ether represented by the following formula 3 in the presence of an acid catalyst. In the above formulae 1-3, R1 is a C1-C6 unsaturated hydrocarbon group containing at least one double bond; R2 is a C2-C6 alkylene group; each of R3 and R4 is a C1-C6 alkyl group; and n is the number of added oxyalkylene group and represents an integer of 3-24.
