摘要

A series of esters and amides of l-alkyl-2-oxo-l, 2-dihydroquinoline-4-carboxylic acid or 2- alkoxyquinoline-4-carboxylic acid containing a basic azabicycloalkyl moiety has been synthesized and evaluated for affinity for the [3Hlquipazine-labeled 5-HT3 receptors. Most of the esters exhibited 10-fold more potent activity than that of ondansetron (1; Ki= 7.6 nM). Lipophilic substituents at the 1-or 2-position of the quinoline ring enhanced affinity for the ...
