5-(N,N-Hexamethylene)-amiloride (5-HMA) 是 amiloride 的衍生物，也是 Na+ H+交换抑制剂，可降低白血病细胞的细胞内 pH (pHi) 并诱导凋亡。

5-TAMRA chloride(91809-66-4 free base) 显示出高效力且活性持续时间短，并且在生理上与孕酮相似。 FGA 的效力大约是黄体酮的 20-25 倍。

Pyrimidinone 8 是一种线性非竞争性可逆抑制剂，针对二价金属转运体 1 (DMT1) 的 Ki 为 20 μM (hDMT1)。Pyrimidinone 8 在细胞表面的 hDMT1 表达上没有影响，并且在不同的细胞外 pH 条件下也保持稳定。它能够抑制 hDMT1 介导的铁摄取，IC50 为 13.8 μM。

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.
