Isorhamnetin 3-O-robinobioside from Nitraria retusa leaves enhance antioxidant and antigenotoxic activity in human chronic myelogenous leukemia cell line K562.[Pubmed: 22913434]
In this report, the isorhamnetin 3-o-robinobioside and its original extract, the ethyl acetate extract, from Nitraria retusa leaves, were evaluated for their ability to induce antioxidant and antigenotoxic effects in human chronic myelogenous leukemia cell line.
METHODS AND RESULTS:
Nitraria retusa products properties were carried out by firstly evaluating their effects against lipid peroxidation induced by H2O2, using the thiobarbituric acid reactive substances species (TBARS) assay, and proceeding to the assay of cellular antioxidant activity, then doing the comet assay. The isorhamnetin 3-o-robinobioside(Isorhamnetin 3-robinobioside) showed a protective effect against lipid peroxidation induced by H2O2. The same natural compound and ethyl acetate extract inhibited oxidation induced by 2,2'-azobis (2-amidinopropane) dihydrochloride in human chronic myelogenous leukemia cells with respectively 50% inhibitory concentration values of 0.225 mg/ml and 0.31 mg/ml, reflecting a significant antioxidant potential. The same two products inhibited the genotoxicity induced by hydroxyl radicals in the same human cell line (by 77.77% at a concentration of 800 μg/ml and by 80.55% at a concentration of 1000 μg/ml respectively).
CONCLUSIONS:
The isorhamnetin 3- o-robinobioside and its original extract, the ethyl acetate extract, from Nitraria retusa leaves, have a great antioxidant and antigenotoxic potential on human chronic myelogenous leukemia cell line K562. CONCLUSIONS: The isorhamnetin 3- o-robinobioside and its original extract, the ethyl acetate extract, from Nitraria retusa leaves, have a great antioxidant and antigenotoxic potential on human chronic myelogenous leukemia cell line K562.
Isorhamnetin 3-robinobioside Description

Solvent: DMSO, Pyridine, Methanol, Ethanol, etc.
Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Potent α-glucosidase and protein tyrosine phosphatase 1B inhibitors from Artemisia capillaris.[Pubmed: 23435948]
As a part of our ongoing effort to identify anti-diabetic constituents from natural sources, we examined the inhibitory activity of the methanol extracts of 12 species of the genus Artemisia, against α-glucosidase and protein tyrosine phosphatase 1B (PTP1B). The methanol extracts of different species exhibited promising α-glucosidase and PTP1B inhibitory activities. Since the methanol extract of Artemisia capillaris exhibited the highest α-glucosidase inhibitory activity together with significant PTP1B inhibitory activity, it was selected for further investigation.
METHODS AND RESULTS:
Repeated column chromatography based on bioactivity guided fractionation yielded 10 coumarins (esculetin, esculin, scopolin, isoscopolin, daphnetin, umbelliferone, 7-methoxy coumarin, scoparone, scopoletin, 6-methoxy artemicapin C), 8 flavonoids (hyperoside, quercetin, isorhamnetin, cirsilineol, arcapillin, Isorhamnetin 3-robinobioside, linarin, isorhamnetin 3-glucoiside), 6 phenolic compounds (1,5-dicaffeoylquinic acid, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid methyl ester, 4,5-dicaffeoylquinic acid, 3-caffeoylquinic acid), and one chromone (capillarisin). Among these compounds, esculetin, scopoletin, quercetin, hyperoside, isorhamnetin, 3,5-dicaffeoylquinic acid methyl ester, 3,4-dicaffeoylquinic acid, and 1,5-dicaffeoylquinic acid exhibited potent α-glucosidase inhibitory activity when compared to the positive control acarbose. In addition, esculetin and 6-methoxy artemicapin C displayed PTP1B inhibitory activity. Interestingly, all isolated dicaffeoylquinic acids showed significant PTP1B inhibitory activity.
CONCLUSIONS:
Therefore, the results of the present study clearly demonstrate the potential of the A. capillaris extract to inhibit α-glucosidase and PTP1B. These inhibitory properties can be largely attributed to a combination of different chemical structures, including coumarins, flavonoids, and dicaffeoylquinic acids, which could be further explored to develop therapeutic or preventive agents for the treatment of diabetes.
