rhein

Rhein (NSC 38629) 从蓼科大黄中提取的一种蒽醌类化合物，有抗炎、抗氧化、抗癌等作用。

Rhein-13C4 is intended for use as an internal standard for the quantification of rhein by GC- or LC-MS. Rhein is an anti-inflammatory anthraquinone found in rhubarb and is the bioactive derivative of its prodrug diacerein . At 10 μM, rhein inhibits IL-1β signaling, suppressing signaling through NF-κB, and reduces the expression of the matrix metalloproteases MMP-1 and MMP-13.1 It inhibits IKKβ (IC50 = 11.8 μM), decreasing iNOS and IL-6 expression in LPS-stimulated macrophages but paradoxically increasing TNF-α, IL-1β, and HMBG1 expression.2 Rhein shows efficacy against pancreatic fibrosis, chronic pancreatitis, and hyperglycemia-induced pancreatic β-cell apoptosis.3,4 It also inhibits angiogenesis of breast cancer cells under normoxic and hypoxic conditions.5

Rhein-8-glucoside calcium (Rhein-8-glucoside calcium salt) salt 是一种从 Saussurea lappa 根的 EtOH 提取物中，分离得到的蒽醌类 hPTP1B 抑制剂，IC50值为11.5 μM，具有抗菌作用。

Rhein 8-Glucoside 是一种蒽醌糖苷，存在于大黄 (rhubarb) 中，显示出泻下活性。

Rhein 8-β-D-glucuronide 是一种应用于糖生物学研究的生化试剂。糖生物学涉及对糖的结构、合成、生物学和进化的研究，包括碳水化合物化学、聚糖形成和降解的酶学过程、蛋白质-聚糖识别以及聚糖在生物系统中的功能。此领域与基础科学研究、生物医学以及生物技术息息相关。

Aporheine is a natural product from Phellinus igniarius.

Diacerein (Fisiodar) 是一种慢效具有白介素-1β 抑制效果的蒽醌类化合物。

6,9-Dichloro-1,2,3,4-tetrahydroacridine is a synthetic intermediate in the synthesis of tacrine-based acetylcholinesterase (AChE) inhibitors.1It is also an intermediate in the synthesis of multifunctional tacrine hybrids that possess radical scavenging, amyloid-β aggregation inhibitory, and or β-secretase 1 (BACE1) inhibitory activities in addition to their activity as AChE inhibitors.2,3 1.Recanatini, M., Cavalli, A., Belluti, F., et al.SAR of 9-amino-1,2,3,4-tetrahydroacridine-based acetylcholinesterase inhibitors: Synthesis, enzyme inhibitory activity, QSAR, and structure-based CoMFA of tacrine analoguesJ.
