Conjugation of tripeptide derivatives with olsalazine, a clinically used anti-inflammatory prodrug, yields small molecules that self-assemble in water to form supramolecular hydrogels that undergo a gel-to-sol phase transition upon reduction, resulting in the controlled release of 5-aminosalicylic acid as the

Sulfasalazine, consisting of 5-aminosalicylic acid bound to sulfapyridine by a diazo bond, was first used for treatment of ulcerative colitis in the early 1940s and later found effective in placebo-controlled trials for acute disease and for long-term maintenance of remission.
