Published: July 2022

Three new glycosylated secondary metabolites, including a new indole alkaloid, pityriacitrin D (), and two new trehalose lipids ( and ), together with three known compounds (-) were isolated from two marine-derived bacterial strains, 168CLC-66.1 and IV19-045. The structures of - were determined by extensive analysis and comparison of their spectroscopic data with literature values. The absolute configurations of sugar moieties were determined by chemical derivatization followed by LC-MS analysis. Cytotoxicity of - against six cancer cell lines was evaluated by SRB assay, and showed moderate activity against all the tested cell lines with GI values ranging from 8.0 to 10.9 µM.

Genome-wide identification of UDP-glycosyltransferases involved in flavonol glycosylation induced by UV-B irradiation in Eriobotrya japonica.

Plant Physiol Biochem

January 2025

College of Agriculture & Biotechnology, Zhejiang University, Hangzhou, 310058, China; Zhejiang Key Laboratory of Horticultural Crop Quality Improvement, Zhejiang University, Hangzhou, 310058, China. Electronic address:

Flavonol glycosides are secondary metabolites important for plant development and stress defense such as UV-B irradiation. UDP-glycosyltransferase (UGT) catalyzes the last step in the biosynthesis of flavonol glycosides. Eriobotrya japonica is abundant in flavonol glycosides, but UGTs responsible for accumulation of flavonol glycosides remain unknown.

ObjectiveThis study aimed to investigate associations between patient activation, healthcare use and clinical outcomes for Aboriginal peoples living with a chronic condition in remote Northern Territory (NT) communities.MethodsA retrospective cohort study was undertaken between 2 April 2020 and 1 April 2022 to measure activation and its associations with chronic conditions secondary prevention treatment targets and healthcare usage: hospitalisations, potentially preventable hospitalisations and patient travel. All Aboriginal peoples enrolled at NT Government health services, who had one or more preventable chronic conditions and were prescribed one or more oral chronic condition medications identified in the Primary Care Information System, were included in the study.

Pickering emulsion stabilized by food grade nanoparticles with stimulus response as a targeted delivery system for lipophilic bioactive compounds has attracted people's attention. In this study, ferulic acid was used to modify saccharified zein to prepare pH-sensitive nanoparticles for stabilizing Pickering emulsion. The structure, interface behavior, stability of Pickering emulsion and gastrointestinal digestion characteristics of nanoparticles in vitro were studied.

Glycosylated peptides isolated from cheese whey have antifreezing activity.

Food Chem

December 2024

Department of Food Science, The University of Tennessee, Knoxville (UTK), TN 37996, United States. Electronic address:

The glycomacropeptide (GMP) present in the cheese whey byproduct can be an excellent antifreezing agent due to its unique molecular structure. The objective of this study was to concentrate this peptide and investigate its ice recrystallization inhibition (IRI) ability. Heat denaturation of the non-GMP proteins and preparative liquid chromatography were used to create fraction 1 (F1) and fraction 2 (F2) and these were tested using the splat assay and a modified sucrose sandwich assay to investigate their IRI activity.

Article Synopsis
  • The study investigates lymph node stromal cell cultures (LNSCs) from oral squamous cell carcinoma (OSCC) patients to understand tumor interactions for better treatment options.
  • Primary cultures were developed from both metastatic and non-metastatic patient nodes, confirming their purity and revealing a variety of cell types.
  • Transcriptomic and cytokine profiling showed different molecular alterations based on node status, with key insights into immune response and potential pathways for metastasis, highlighting the relevance of these models for future cancer research.
