Syzygium boisianum (Gagnep.) Merr. & L.M.Perry, locally named Tram bois, is widely distributed in primary or secondary forests of Vietnam, Thailand, and China. [6] For the first time, the current report provides information on chemical compositions in essential oil of S. boisianum leaves, collected from the northern part of central Vietnam. The obtained oil was also used to assess its antibacterial effects. The biological potential is highlighted by the molecular docking study.

Erwinia is a genus of Enterobacteriacea containing mostly pathogens, which cause soft rot disease in many ornamental plants and crops, including Asparagus officinalis. Chemical treatments to control Erwinia have lost their attractiveness because of the development of resistant strains and the negative impacts on the environment and human health.

The Maillard reaction products (MRPs) were synthesized during the gamma irradiation of mixtures of chitosan (CT) and/or oligochitosan (OC) with glucosamine (GA) at the dose of 25 kGy and investigated their some characteristics. The formations of MRPs were determined by UV-vis spectromectric analyses at the wavelength of 284 nm and 420 nm.

This work reports the surface modification of polyacrylonitrile (PAN) fibers by graft copolymerization to ensure the decoration of homogenous and dense Ag nanoparticles. Two facile and subsequent modification processes resulted in a PAN fiber composite with an intact fibrous structure, sufficiently conductive for antistatic application and antibacterial activity. In the first step, some chemically attractive monomers and monomer mixtures, such as acrylic acid (AA), AA-itaconic acid (AA-IA), AA-acrylamide (AA-AAm), were introduced to the fiber surface by grafting.

The chemical composition, antioxidant properties and antibacterial activities of different extracts (water, ethanol, acetate ethyl and hexane) and essential oil from Platycladus orientalis leaves were analysed in this study. The essential oil was extracted by hydrodistillation, and its chemical composition was determined by gas chromatography coupled to mass spectrometry (GC-MS).

We report herein a new chemical platform for coupling chitosan derivatives to antimicrobial peptide dendrimers (AMPDs) with different degrees of ramification and molecular weights via thiol-maleimide reactions. Previous studies showed that simple incorporation of AMPDs to polymeric hydrogels resulted in a loss of antibacterial activity and augmented cytotoxicity to mammalian cells.

The leaves of Combretum quadrangulare Kurz. collected in Long An Province were chemically investigated using multiple chromatographic methods. Four compounds, 5-hydroxy3,7,4′-trimethoxyflavone (1), ayanin (2), kamatakenin (3), and luteolin (4) were isolated and elucidated. Their chemical structures were elucidated by comparing their spectroscopic data with those in previous reports.

Moxifloxacin (MOX) is a fourth-generation synthetic fluoroquinolone antibacterial agent with many important therapeutic properties. Fluorescence quenching was used to study the interaction of MOX with calf thymus DNA (ctDNA) in aqueous solution. As the most common genetic material of various biosomes in nature, deoxyribonucleic acid (DNA) plays a key role in different kinds of vital processes including gene expression, mutagenesis, cell death, etc.

Two novel clusters of cephalosporin based on calixarene were synthesized directly or by ring expansion of the penicillin arms of calixpenams to the corresponding cephem arms via sulfoxide intermediates. Antibiotic tests showed that calixcephems have a noteworthy increase in antibacterial activity against methicillin-resistant strains of Staphylococcus aureus (MRSA) with respect to parent calixpenams and their corresponding single cephems.
