artemisia vestita/phosphatase

Artemisia roxburghiana is used in traditional medicine for treating various diseases including diabetes. The present study was designed to evaluate the antidiabetic potential of active constituents by using protein tyrosine phosphatase 1B (PTP1B) as a validated target for management of diabetes.

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

Signal transducers and activators of transcription (STAT)-3 is a latent cytosolic transcription factor that has been closely associated with survival, proliferation, chemoresistance, and metastasis of tumor cells. Whether the anti-proliferative, pro-apoptotic, and anti-metastatic effects of

Considerable attention has been paid to protein tyrosine phosphatase 1B (PTP1B) inhibitors as a potential therapy for diabetes, obesity, and cancer. Ten caffeoylquinic acid derivatives (1-10) from leaves of Artemisia princeps Pamp. (Asteraceae) were identified as natural PTP1B inhibitors. Among

The phytohormone abscisic acid (ABA) plays an important role in plant development and environmental stress response. Additionally, ABA also regulates secondary metabolism such as artemisinin in the medicinal plant Artemisia annua L. Although an earlier study showed that ABA receptor, AaPYL9, plays a

BACKGROUND Upon contact with a wet surface, mature pollen grains hydrate and release proteins including allergens. Knowledge of the release mechanism of allergens that are mainly localized intracellularly may allow the design of strategies for inhibition of allergen release and the consequent

In the present study, we evaluated the protective activity of an aqueous extract of Artemisia absinthium against CCl4-induced hepatic damage in rats. The protective activity of this extract at three doses (2.5, 5, and 10 ml/ kg, once orally) against CCl4-induced oxidative damage (1.5 ml/kg, once

BACKGROUND Infusions of aerial parts of Artemisia vulgaris L. (Asteraceae) are used in herbal medicine to treat several disorders, including hepatosis. OBJECTIVE Evaluation of in vivo hepatoprotective effects of A. vulgaris infusion (VI) and inulin (VPI; i.e., the major polysaccharide of

One new (4) and twelve known phenolic compounds (1-3, 5-13) were isolated from a 70% MeOH extract of the aerial parts of Artemisia iwayomogi. The new compound was identified as 7,8-dimethoxy-coumarin-9-O-(6'-O-(E)-coumaroyl)-beta-D-glucopyranoside (4) and named iwayomin. The effects of compounds

Artemisia arborescens is an aromatic shrub whose essential oils are considered a potential source of molecules with industrial and pharmaceutical interest. The chemical profile of A. arborescens essential oils (EOs) was shown to be quite variable and various chemotypes have been

BACKGROUND Currently, natural products have been shown to exhibit interesting biological and pharmacological activities and are used as chemotherapeutic agents. The purpose of this study, conducted on Wistar rats, was to evaluate the beneficial effects of Artemisia arborescens oil on

Two strains of bean rhizobia, Rhizobium vigna 01 (slow-growing Rhizobium) and Rh. vigna 03 (fast-growing Rhizobium), were adopted to study allelopathic effect of artemisinin on the rhizobia. The results showed a significant inhibition of the reproduction and growth of rhizobium by artemisinin. After

Artemisiaafra Jacq. ex Willd. is a widely used medicinal plant in South Africa for the treatment of various diseases. In this study, the effect of the herb on isoproterenol (ISO)-induced myocardial injury in rats was investigated. Pretreatment with the aqueous leaf extract of the plant at 100 and

Dehydroleucodine (DhL), a sesquiterpenic lactone, was isolated and purified from aerial parts of Artemisia douglasiana Besser, a medicinal herb used in Argentina. DhL is an alpha-methylene butyro-gamma-lactone ring connected to a seven-membered ring fused to an exocyclic alpha,beta-unsaturated
