rhein

Rhein (NSC 38629) is an anthraquinone compound extracted from Polygonaceae Rheum Officinale with anti-inflammation and antitumor activities.

Rhein-8-O-beta-D-glucopyranoside(Rhein-8-glucoside calcium (Rhein-8-glucoside calcium salt) salt) shows moderate bioactivity against human Protein Tyrosine Phosphatase 1B (hPTP1B) in vitro.

D-Arabitol is a polyol that can lead to neurotoxicity when accumulated in the body.

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 (Standard) is a reference standard for research and analysis in studies involving Rhein. Rhein (NSC 38629) is an anthraquinone compound extracted from Polygonaceae Rheum Officinale with anti-inflammation and antitumor activities.

Rhein 8-Glucoside (Standard) is a reference standard for research and analysis in studies involving Rhein 8-Glucoside. D-Arabitol is a polyol that can lead to neurotoxicity when accumulated in the body.

Rhein 8-β-D-glucuronide is a biochemical reagent utilized in glycobiology research. Glycobiology examines the structure, synthesis, biology, and evolution of sugars, encompassing carbohydrate chemistry, glycan formation and degradation enzymology, protein-glycan recognition, and glycan roles in biological systems. This field is closely linked to fundamental research, biomedicine, and biotechnology.

Aporheine is a natural product from Phellinus igniarius.

Diacerein (Fisiodar) is a prodrug which is metabolized to rhein. It is currently approved in France for the treatment of osteoarthritis although the use of diacerein is restricted due to the side effects including sevre diarrhea [L780]. Diacerein is under investigation for the treatment of Insulin Resistance, Diabetes Mellitus (Type 2), and Diabetes-Related Complications.

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.
