[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is an agent derived from sulfasalazine, an antiinflammatory agent.  Mesalamine may reduce inflammation through inhibition of cyclooxygenase and prostaglandin production. Following rectal or oral administration, only a small amount of mesalamine is absorbed; the remainder, acting topically, reduces bowel inflammation, diarrhea, rectal bleeding and stomach pain.
