To explore the better prodrug of 4-aminosalicylic acid (4-ASA) with higher activity and less side effects against the inflammatory bowel disease.4-ASA, after a succession of synthesis process, was conjugated with various carrier molecules to get seven azo derivatives of 4-ASA.All compounds were characterized by FT-IR, ¹H NMR, ¹³C NMR spectras in detail.New derivatives of 4-ASA were definituded.
