Synthesis and anti-inflammatory and analgesic activities of pyridyloxy- and phenoxyalkanoic acid derivatives

Abstract

Synthesis of pyridyloxy-, pyridyloxyphenoxy- and phenoxylphenoxyalkanate derivatives and their anti-inflammatory and analgesic activities were investigated. Analysis of structure-activity relationships showed that in pyridyloxyalkanoic acid derivatives anti-edematous potency was associated with the presence of chlorophenoxypropionic acid moiety and 2-nitrated methyl propionates contributed to the analgesic activity.
