Abstract:
PURPOSE: Provided are the novel NMDA receptor antagonist, 4-(3-substituted-propyloxy)-quinoline-2-carboxylic acid derivatives and the preparation method thereof. CONSTITUTION: The derivatives are represented as shown in the chemical formula 1, where A represents carbamate, amide, thiourea, sulfonylurea, acylthiourea, thiocarbamate, amidine, guanidine, imidate, thioimidate, phosphorylamide, sulfonamide, sulfonthiourea or amines and R represents alkyl (C1¯C20), aryl (C6¯C12), aralkyl, heterocycles, carbocycles (C3¯C14), fused bicyclic, hydrogen or cyano groups. The synthetic process comprises the steps of alkylating 5,7-dichlorokynurenic acid methylester with 1,3-dibromopropane; substitution of the bromine with NaN3 to make azidomine; reducing the resultant to amine compound with Pd-catalyst; converting to amide with the corresponding isocyanate, thioisocyanate or acid chloride and finally hydrolysing the ester group in the parent moiety to make the compound of formula 1. They are strong and unique antagonist acting on the coupling position of the strychnine non-susceptive glycine in the NMDA receptor complex and penetrate effectively into central nervous system. They are effective in the treatment of neurodegeneration, especially useful for the CNS damages effected by the diseases such as heart attack, low blood sugar, local anemia and heart beat halt arising from the low oxygen concentration caused by the external wounds or anemia.
