Description

General description

Emodin is an anthraquinone derivative, extracted from rhubarb (Rheum palmatum). It has antibacterial, anti-neoplastic, anti-inflammatory and anti-angiogenesis properties. Emodin exhibits cytotoxic effects, apoptosis and stimulates the expression of hypoxia-inducible factor 1α, glutathione S-transferase P and N-acetyltransferase. It prevents the growth of prostate cancer cells. Emodin is used to treat constipation and hemorrhoid. It displays immunosuppressive and anti-diabetic effects.

Application

Emodin has been used:

• to investigate its regulatory mechanisms on lipopolysaccharide (LPS)-induced inflammatory injury in myocarditis
• as a reference standard for the development and validation of high performance liquid chromatography (HPLC)-photodiode array (PDA) assay method
• to inhibit Tau aggregation
• for direct binding assay

Biochem/physiol Actions

Inhibitor of NF-κB activation and adhesion molecule expression. Casein Kinase 2 (CK2) inhibitor.
