sulfasalazine

Sulfasalazine (Azulfidine) 是一种合成的水杨酸衍生物，对含有弹性蛋白的结缔组织具有亲和力，并配制成前药。Sulfasalazine 可以诱导铁死亡，抑制 NF-κB、TGF-β 和 COX-2。

Sulfasalazine-d4 是 Sulfasalazine 的氘代化合物。Sulfasalazine 的 CAS 号为 599-79-1。Sulfasalazine 是一种合成的水杨酸衍生物，对含有弹性蛋白的结缔组织具有亲和力，并配制成前药。

Sulfapyridine (2-Sulfapyridine) 是一种磺酰胺类抗生素，是 Sulfasalazine 的代谢产物。它抑制重组 P. carinii 二氢蝶呤合成酶，IC50为 0.18 μM。它具有抗菌，抗炎和抗风湿作用。

GPX4-AUTAC 是一种靶向 GPX4 的自噬介导降解剂 (AUTAC)，由抑制剂 ML162-yne、降解标签 FBnG 和 glycol linker 构成。它可以促进 E3 连接酶 TRAF6 对 GPX4 的泛素化修饰，并加强与 GPX4 和 p62 的结合，实现 GPX4 的选择性自噬依赖性降解。GPX4-AUTAC 显著诱导铁死亡 (ferroptosis)，在乳腺癌细胞、乳腺癌来源的类器官 (PDOs) 和 MDA-MB-231 肿瘤异种移植小鼠模型中展现出强大的抗癌活性，与 Sulfasalazine (SAS) 或化疗药物 (Paclitaxel 或 Cisplatin) 联合使用时具有明显的协同效应。

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.
