rubus idaeus/tyrosine

Protein tyrosine phosphatase 1B (PTP1B) has led to an intense interest in developing its inhibitors as anti-diabetes, anti-obesity and anti-cancer agents. The fruits of Rubus chingii (Chinese raspberry) were used as a kind of dietary traditional Chinese medicine. The methanolic extract of R. chingii

This paper presents a study on chemical composition, antimicrobial, antioxidant and tyrosinase inhibitory properties of the essential oil from leaves of Rubus pungens var. oldhamii (REO). The major component of the REO is sesquiterpenes (36.04%), which consists of 1,5-Cyclooctadiene,3-(1-me

The vascular endothelial growth factor (VEGF) plays a key role in angiogenesis, which is a process where new blood vessels develop from the endothelium of a pre-existing vasculature. VEGF exerts its activity by binding to its receptor tyrosine kinase, KDR/Flk-1, which is expressed on the surface of

Berries have been found to inhibit colon carcinogenesis in animal models, and thus represent a potential source of compounds for prevention and treatment of colorectal cancer. The mechanistic basis for their effects is not well understood. We used human colon carcinoma cells and Min mice to

There is growing evidence that fruit polyphenols exert beneficial effects on the metabolic syndrome, but the underlying mechanisms remain poorly understood. In the present study, we aimed to analyse the effects of polyphenolic extracts from five types of Arctic berries in a model of diet-induced

Many potential health benefits of raspberry (Rubus idaeus L.) leaves were attributed to polyphenolic compounds, especially flavonoids. In this study, the methanol extract of R. idaeus leaves showed significant protein tyrosine phosphatase-1B (PTP1B) inhibitory activity with IC50 value of 3.41 ± 0.01

Seven plant species, belonging to different families, were collected in the eastern part of the Republic of Congo (Kivu) based on ethnopharmacological information. Their dichloromethane and methanolic extracts were tested for biological activity. Five of the seven collected plants exhibited
