5-aminosalicylic acid

5-Aminosalicylic Acid (5-ASA) 是一种特异性的PPARγ激动剂，还抑制 p21-激活激酶1(PAK1) 和NF-κB，具有抗炎活性。

N-acetyl-5-Aminosalicylic Acid (N-Acetyl mesalazine) 是美沙拉嗪的主要代谢产物。

Balsalazide sodium hydrate (Balsalazide disodium) 可通过调节IL-6 STAT3通路起抑癌作用，可用于治疗炎症性肠病。

Olsalazine disodium (Dipentum) 是抗炎化合物，可作用于溃疡性结肠炎和炎症性肠病。

Olsalazine-13C6is intended for use as an internal standard for the quantification of olsalazine by GC- or LC-MS. Olsalazine is an orally bioavailable prodrug form of the anti-inflammatory agent 5-aminosalicylic acid that is cleaved by bacterial azo reductases in the gut to generate active 5-ASA.1In vitro, olsalazine increases ion transport in isolated rabbit distal ileum when applied to the luminal side (ED50= 0.3 mM) and stimulates fluid transport in rat jejunum when used at a concentration of 5 mM.2,3Olsalazine (150 mg/kg for 8 days) improves stool consistency and decreases occult and gross bleeding as well as myeloperoxidase (MPO) activity and leukotriene B4levels in colon tissue in a mouse model of acute colitis induced by dextran sulfate .4Olsalazine also inhibits bovine xanthine oxidasein vitro(IC50= 3.4 mg/L) and lowers serum uric acid levels in a mouse model of hyperuricemia induced by oxonic acid when administered at a dose of 20 mg/kg.5Formulations containing olsalazine have been used in the treatment of inflammatory bowel disease (IBD) and ulcerative colitis. 1.Nugent, S.G., Kumar, D., Rampton, D.S., et al.Intestinal luminal pH in inflammatory bowel disease: Possible determinants and implications for therapy with aminosalicylates and other drugsGut48(4)571-577(2001) 2.Pamukcu, R., Hanauer, S.B., and Chang, E.B.Effect of disodium azodisalicylate on electrolyte transport in rabbit ileum and colon in vitro.
