The outcomes are to be compared with typical drugs given that compounds are examined against gram-positive and gram-negative strains of bacteria and fungus. Against bacterial strains, products with nitro, methyl, and bromo substituents in the p-position of the benzene ring, as well as products with the nitro group at the m-position, showed very excellent activities against bacterial strains, while compounds with chloro substituent at p-position and m-position demonstrated good activity against the fungal strains Aspergillus niger and Fusarium javanicum.

In this study, a facile synthesis and grafting method is reported for tetradentate Cu(II) Schiff base complex onto the surface of graphene oxide (GO). The Schiff base Cu-complex was synthesized through the condensation reaction between 2,3-diamino pyridine and 2-hydroxy-1-naphthaldehyde, followed by the addition of Cu(II) ion to afford N2O2-Cu(II) complex.

Resistance to pathogenic bacteria may lead to serious health problems. Scientists found that discovering novel antimicrobial compounds is possible by exploring rarely investigated environments. Therefore, this work focused on isolating and identifying some fungal strains collected from the Co To sea. We tested whether such strains can produce compounds with vital activities, including antibacterial and antifungal. The antimicrobial activity of the marine fungi crude extracts was performed by the Bioassay method in a 96-well tray.

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.

Antibacterial packaging represents an active packaging solution crafted to uphold the quality and safety of products. One of the popular polymer used in food packaging is Linear Low-Density Polyethylene (LLDPE), due to its low cost, ease of processing, and high mechanical properties. Polymer blend based on LLDPE and antibacterial agent PHMG were prepared in the presence of PE-g_AM compatibilizer and DCP initiator.

The biological activities of E. ciliata essential oils (Ec EOs) in Vietnam have yet to be thoroughly studied and have received less attention than other species of genus Elsholtzia in the world. In this study, we evaluated the antioxidant, antimicrobial, and anticancer of Ec EOs and examined their chemical compositions. Fresh leaves of E. ciliata were hydro-distilled to yield essential oil of 0.82% dry weight, respectively.

Magnolia citrata Noot. & Chalermglin was collected in the Central Highlands of Vietnam and examined for its essential oils’ chemical compositions and antimicrobial activities. The essential oils were obtained from the leaves, twigs, and stem barks of M. citrata using hydrodistillation, then analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) and evaluated for antimicrobial activities.

This study aimed to isolate and identify marine fungi from Bai Tu Long Bay and assess their antimicrobial potential. We successfully isolated twenty strains of marine-derived fungi. The crude extracts from these fungi were tested against pathogenic microorganisms. All twenty strains exhibit some degree of growth inhibition against the tested microorganisms.

The methanol extracts as well as some compounds from this plant exhibited anti-inflammatory, antimicrobial activity, antioxidant, hepatoprotective and anti-cancer effect, and antiosteoporotic. On going to search for bioactive components from the Vietnamese plant, this paper reported the isolation of seven phenolic compounds including one new from the aerial parts of A. ilicifolius. The cytotoxic activity of the isolates against two cancer cell lines (HepG2 and SK-LU1) were also screened and reported herein.

The essential oils were also tested for their antioxidant, anti-imflammatory, antimicrobial and cytotoxic activities. The HD essential oil sample showed inhibitory activity against 6/8 tested microorganisms, i.e., Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus subtillis, Candida albicans, and Saccharomyces cerevisiae. The MHD and EHD exhibited the inhibitory activity against three strains E. coli, A. niger and F. oxysporum. The UHD inhibited E. coli and F. oxysporum.

In ebook "Peptide and protein interaction with membrane systems: Applications to antimicrobial therapy and protein drug delivery" the study of peptide-membrane interactions has been carried out using model membranes. It has been shown, indeed, that peptides feature the same activity on these systems. The most common membrane model is represented by lipid vesicles (liposomes), a simple but realistic system for physical and chemical studies of a variety of phenomena.
