摘要

Several chloro and fluoronicotinic acids have been examined for hypoloipidemic activity in dogs (Carlson et. al., 1972). It was demonstrated that 5-fluoronicotinic acid, 6- fluoronicotinic acid, and 5-chloronicotinic acid were effective for the supresssion of elevated free fatty acid levels, with the fluoroacids having longer duration. A few simple alkyl esters of these acids also showed some activity , pre- sumably due to in vivo hydrolysis to the acids. While it would seem feasible to study possible hypolipidemic activi- ties of nicotinic acids and esters with a dual combination of fluorine and chlorine on the pyridine ring, such studies have been limited by the relative nonavailability of these com- pounds.
