Potassium 1H-indol-3-yl sulfate (Potassium 3-indoxyl sulfate) 是人芳烃受体(AhR)的激动剂。芳烃受体(AhR)最近被发现是免疫炎症条件的病理生理调节剂,Potassium 1H-indol-3-yl sulfate 已被证明是AhR的配体。Potassium 1H-indol-3-yl sulfate 也是膳食蛋白质中色氨酸的代谢物。色氨酸被肠道细菌代谢为吲哚,吲哚被吸收到血液中,然后在肝脏中进一步代谢为硫酸吲哚,通常通过尿液排出体外。在肾功能受损的慢性肾病患者中,Potassium 1H-indol-3-yl sulfate 可作为尿毒症毒素在血清中积累,诱导氧化应激并加速疾病进展。250 μM Potassium 1H-indol-3-yl sulfate 可诱导NF-Κb活化,促进大鼠近端小管细胞TGF-β1和Smad3的表达,与促纤维化活性相关。

产品描述 | Potassium 1H-indol-3-yl sulfate (Potassium 3-indoxyl sulfate) is an agonist for the human Aryl Hydrocarbon Receptor (AhR). The Aryl Hydrocarbon Receptor (AhR) has recently emerged as a pathophysiological regulator of immune-inflammatory conditions and potassium 1H-indol-3-yl sulfate has been shown to be a ligand for AhR. Potassium 1H-indol-3-yl sulfate is also a metabolite of tryptophan derived from dietary protein. Tryptophan is metabolized by intestinal bacteria into indole, which is absorbed into the blood and then further metabolized to indoxyl sulfate in the liver, which is normally excreted in urine. In chronic kidney disease patients where renal function is compromised, potassium 1H-indol-3-yl sulfate can accumulate in serum as a uremic toxin, inducing oxidative stress and accelerating progression of the disease. Potassium 1H-indol-3-yl sulfate at 250 μM can induce the activation of NF-Κb, promoting the expression of both TGF-β1 and Smad3 expression in proximal tubular cells of rats, which is associated with profibrotic activity. |
