生物活性

Emodin (Frangula emodin), an anthraquinone derivative, is an anti-SARS-CoV compound. Emodin blocks the SARS coronavirus spike protein and angiotensin-converting enzyme 2 (ACE2) interaction[1]. Emodin inhibits casein kinase-2 (CK2). Anti-inflammatory and anticancer effects[2]. Emodin is a potent selective 11β-HSD1 inhibitor with the IC50 of 186 and 86 nM for human and mouse 11β-HSD1, respectively. Emodin ameliorates metabolic disorder in diet-induced obese mice[3].

Emodin (10-400 μM) blocks the binding of S protein to ACE2 in a dose-dependent manner with the IC50 value of 200 μM[1].
Emodin (5-50 μM) inhibits the S protein-pseudotyped retrovirus infectivity in a dose-dependent manner. Emodin blocks the SARS-CoV S protein binding to Vero E6 cells[1].
Emodin inhibits casein kinase-2 (CK2) with IC50s of 5.9, 30.0, and 7.1 μM for CK2α Wild-type, Ile174Ala mutant, and His160Ala mutant at ATP concentration is 50 μM, respectively. The IC50s are 1.40 and 38.00 μM for CK2α Wild-type, and Val66Ala mutant at ATP concentration is 10 μM[2].
Emodin exhibits low inhibitory activity against mouse and human 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2), with an IC50 higher than 1 mM, indicating that Emodin is more than 5000-fold selective for the human and mouse 11β-HSD1 enzymes over the type 2 isoenzyme[3].

生物活性

Aloe emodin is a hydroxyanthraquinone present in Aloe vera leaves, has a specific in vitro and in vivo antitumor activity. IC50 value: Target: in vitro: aloe-emodin treatment led to the dissociation of heat shock protein 90 (HSP90) and ER α and increased ER α ubiquitination. Protein fractionation results suggest that aloe-emodin tended to induce cytosolic ER α degradation [1]. Aloe-emodin, a natural compound found in aloe, inhibited both proliferation and anchorage-independent growth of PC3 cells. Protein content analysis suggested that activation of the downstream substrates of mTORC2, Akt and PKCα, was inhibited by aloe-emodin treatment. Pull-down assay and in vitro kinase assay results indicated that aloe-emodin could bind with mTORC2 in cells and inhibit its kinase activity [2]. Of three anthraquinone derivatives, aloe-emodin, with a lower cytotoxicity showed concentration-dependently reducing virus-induced cytopathic effect and inhibiting replication of influenza A in MDCK cells. Galectin-3 also inhibited influenza A virus replication. Proteomic analysis of treated cells indicated galectin-3 up-regulation as one anti-influenza A virus action by aloe-emodin. Since galectin-3 exhibited cytokine-like regulatory actions via JAK/STAT pathways, aloe-emodin also restored NS1-inhibited STAT1-mediated antiviral responses in transfected cells: e.g., STAT1 phosphorylation of interferon (IFN) stimulation response element (ISRE)-driven promoter, RNA-dependent protein kinase (PKR) and 2’5′,-oligoadenylate synthetase (2’5′,-OAS) expression [3]. AE downregulated mRNA expression and promoter/gelatinolytic activity of Matrix Metalloproteinase (MMP)-2/9, as well as the RhoB expression at gene and protein level. AE suppressed the nuclear translocation and DNA binding of NF-κB [4]. in vivo: Aloe-emodin also exhibited tumor suppression effects in vivo in an athymic nude mouse model [2].
