Methacholine (Acetyl-β-methylcholine) bromide 是一种有效的muscarinic-3 (M3)激动剂。Methacholine bromide 直接作用于平滑肌上的乙酰胆碱受体,导致支气管收缩和气道变窄。Methacholine bromide 对识别支气管高反应性 (BHR) 显示出高灵敏度,BHR 是哮喘的重要特征。Methacholine bromide 可用于测量气道高反应性 (AHR),作为评估具有哮喘样症状和正常静息呼气流速的个体的诊断辅助[2]。 | |||

Indoxyl sulfate-d5 is intended for use as an internal standard for the quantification of indoxyl sulfate by GC- or LC-MS. Indoxyl sulfate is a uremic toxin and a metabolite of tryptophan. It is formed via sulfation of indole, an intermediate generated from tryptophan by intestinal bacteria, by the sulfotransferase (SULT) isoform 1A1 variant 2 (SULT1A1*2) in the liver. Indoxyl sulfate activates the aryl hydrocarbon receptor (AhR) in HepG2 40/6 hepatoma cells (EC50 = 12.1 nM in a reporter assay). It also inhibits the organic anion transporter (OAT) isoforms OAT1 and OAT3 (Kis = 34.2 and 74.4 µM, respectively for the rat transporters) in S2 proximal tubule cells. Indoxyl sulfate (0.2 and 1 mM) increases superoxide anion and nitric oxide levels in isolated human mononuclear blood cells. It increases serum creatinine and blood urea nitrogen (BUN) levels in the 5/6 nephrectomized rat model of chronic renal failure when administered at a dose of 50 mg/kg. | |||

Dendrogenin A (DDA) 作为一种选择性肝X受体(LXR)调节剂(SLiM)、胆固醇环氧水解酶(ChEH; Ki = 120 nM)的抑制剂及胆固醇的活性代谢产物,通过DDA合成酶将5,6α-环氧胆固醇与组胺结合形成。DDA在非癌性人乳腺上皮细胞和上皮黑色素细胞中存在,但在多种乳腺癌细胞或黑色素瘤细胞中未发现,且在分离的人乳腺肿瘤组织中仅以低水平存在。它抑制22(R)-羟基胆固醇诱导的LXRβ和LXRα激活(分别以IC50 = 76和362 nM),但也是LXR的部分激动剂,在B16/F10小鼠黑色素瘤细胞中增加Nur77、NOR-1、LC3-I和LC3-II的蛋白水平。DDA选择性调节LXRα和LXRβ,而非孕烯X受体(PXR)、芳香烃受体(AhR)、维生素D受体(VDR)、维甲酸X受体γ(RXRγ)、维甲酸受体α(RARα)、过氧化物酶体增殖物激活受体α(PPARα)、PPARγ、糖皮质激素受体、雄激素受体、雌激素受体α(ERα)及ERβ在2.5 µM下。此外,DDA在2.5和5 µM的浓度下增加B16/F10和SK-MEL-28癌细胞中LC3-II的蛋白水平,并在2.5 µM时诱导这些细胞类型的自噬细胞死亡。DDA (0.37 µg/kg)在B16/F10小鼠黑色素瘤模型和TS/A小鼠乳腺癌模型中减缓肿瘤生长,并在体内外诱导癌细胞分化。 |

TMPJ-00423 | TIM-1/KIM-1/HAVCR1 Protein, Mouse, Recombinant (His) | Mouse | Human Cells | ||
TIM-1/KIM-1/HAVCR belongs to the immunoglobulin superfamily that cosisits 305 amino acid (aa). It is expressed by stimulated T-cells. TIM-1/KIM-1/HAVCR may play a role in T-helper cell development and the regulation of asthma and allergic diseases. Receptor for TIMD4. And may have a role in kidney injury and repair. Belongs to the T-cell and airway phenotype regulator (Tapr) locus, a single chromosomal region that confers reduced T-helper type 2 responsiveness and protects against airway hyperactivity (AHR), the hallmark of human asthma.
