Four new diastereoisomeric neolignan glycosides from the root bark of Lycium chinense Miller. and their α-glucosidase inhibitory activity.

Four new diastereoisomeric neolignan glycosides (1-4) along with nine known lignan glycosides (5-13) were isolated from the root bark of Lycium chinense Mill. Their structures with absolute configurations were elucidated on the basis of NMR spectroscopy, ECD, Mo(OAc)-induced ECD spectra, enzymatic hydrolysis and acid hydrolysis. The isolated compounds were evaluated for their α-glucosidase inhibitory activity.

[Method and application of proteomics in study of targets of traditional Chinese medicines].

The study on the targets of traditional Chinese medicine is an important part of researchers using modern scientific language to clarify the mechanism of traditional Chinese medicine. However, the research on the targets of Chinese medicine is full of challenges due to the complexity of active ingredients. As a branch of systems biology, proteomics focus on specific proteins in living organisms from a holistic perspective, which significantly improves the efficiency of targets discovery and has obvious advantages in the research of targets of Chinese medicine.

The antitumor activity of naturally occurring chromones: A review.

Chromones are a group of compounds widely distributed in nature with wide range of biological activities, including antitumor, antimicrobial, antiviral, anti-inflammatory, antioxidant, and so on. This review mainly summarizes chromones with antitumor activity in nature and classifies them into three groups, including chromanones, simple chromones, and fused chromones. They exhibit antitumor activity through broad range of mechanisms including cytotoxicity, antimetastasis, antiangiogenesis, chemoprevention, immune regulation, etc.
