title: Nonsteroidal antiinflammatory agents. 2. [(Heteroarylamino)phenyl]alkanoic acids.
abstract: A series of [(heteroarylamino)phenyl]alkanoic acids having pyridine, quinoline, or pyrimidine as the heteroaryl moiety was prepared as potential antiinflammatory agents. Among them, 2-[4-(2-pyridylamino)phenyl]propionic acid (14b) showed excellent antiinflammatory and analgesic activities with less tendency to cause gastric side effects. Structure-activity relationships are discussed.
