Objectives: To use molecular docking and dynamic simulation to investigate the inhibitory action of chlorogenic acid (CHA) and its analogues against sortase A of Staphylococcus aureus.
Results: Five novel, natural inhibitors with different activities were discovered for sortase A (SrtA). The inhibition mechanism of the novel inhibitors was consistent with the mechanism of CHA, which was reported previously by Wang et al. (Front Microbiol 6:1031, 2015). Based on structure-activity relationship analysis, the hydroxyl moiety (C1) of the inhibitors is critical in the catalytic region of SrtA, which could be confirmed by the calculation of the binding free energy between SrtA and the inhibitors.
Conclusions: The mechanism obtained by molecular dynamics simulation is thus useful for the development of novel, selective SrtA inhibitors.

Selenium and boron can alleviate lead (Pb) toxicity in plants, but their stress resistance mechanisms in tobacco remain unclear. The aim of this study was to investigate the effects of Se/B application on lead-induced oxidative stress, subcellular distribution, cell wall properties, and Pb accumulation. Additionally, a comprehensive analysis of transcriptomics and metabolomics data was conducted.

Eucommia ulmoides Oliver leaf is rich in chlorogenic acid, which has antioxidant, antiviral, and anti-inflammatory activities. In this work, a new and green strategy for functional hyper-crosslinked adsorption resin based on Friedel-Crafts reaction of pendant vinyl groups in divinylbenzene with anhydrous ethanol and acrylamide grafting polymerization was developed, and the obtained HCREt-AM resin had excellent performance on chlorogenic acid separation from Eucommia ulmoides Oliver leaf extract. Adsorption isotherm and kinetics study showed the adsorption process fitted by Langmuir adsorption isotherm and pseudo-second-order kinetic equation.

Although floral morphology in ornamental chrysanthemums has been widely investigated, its genetic basis in medicinal varieties such as Chrysanthemum morifolium cv. 'Hangju' remains largely unexplored, despite its direct relevance to both capitulum development and medicinal quality. To address this gap, we performed transcriptome profiling of ray and disc florets from wild-type and mutant plants, which led to the identification of two MYB-related transcription factor genes, CmDIV-like and CmRAD1, as differentially expressed and potentially associated with altered floral symmetry.

Aster incisus is a perennial herbaceous plant belonging to the Asteraceae family, known for its pharmacologically active secondary metabolites. In this study, we conducted a comparative profiling and quantification of secondary metabolites in A. incisus extracts cultivated in two regions, Eumseong (AIE) and Inje (AII), using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and high-performance liquid chromatography with a variable wavelength detector (HPLC/VW).
