Balsalazide synthesis: Biorex Laboratories, GB 2080796 (1986). Starting material is 4-aminohippuric acid, obtained by coupling para-aminobenzoic acid and glycine. That product is then treated with nitrous acid to give the diazonium salt. Reaction of this species with salicylic acid proceeds at the position para to the phenol to give balsalazide.
English: Skeletal formula of balsalazide (brand names Giazo ®, Colazal ®, Colazide ® and others)—an anti-inflammatory drug (derivative of 5-aminosalicylic acid), used to treat ulcerative colitis in men. Created with ChemDoodle 7.0.2 and Adobe Illustrator CC.
It is also the active component of the prodrug balsalazide along with the inert carrier molecule 4-aminobenzoyl-beta-alanine. [21] It is in the category of disease-modifying antirheumatic drugs (DMARDs) family of medications. [22] It is unclear exactly how it works. [22] Mesalazine is claimed to be a PPAR-γ agonist. [23]

Ozanimod, sold under the brand name Zeposia, is an immunomodulatory medication for the treatment of relapsing multiple sclerosis and ulcerative colitis. [3] [4] [6] [7] It acts as a sphingosine-1-phosphate receptor (S1PR) agonist, sequestering lymphocytes to peripheral lymphoid organs and away from their sites of chronic inflammation.
The azide functional group can be shown by two resonance structures. An organic azide is an organic compound that contains an azide (– N 3) functional group. [1] Because of the hazards associated with their use, few azides are used commercially although they exhibit interesting reactivity for researchers.
In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −.It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1]
Management of ulcerative colitis involves first treating the acute symptoms of the disease, then maintaining remission. Ulcerative colitis is a form of colitis, a disease of the intestine, specifically the large intestine or colon, that includes characteristic ulcers, or open sores, in the colon.
