Evaluation of antimicrobial activity
-
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.

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.

In the last few decades, pyrazoline-based substances have emerged as potential antimicrobial and anticancer candidates. In concern with antimicrobial activity, this study aims to build a docking model to predict the structure of potential 2-pyrazoline derivatives. The cytotoxicity of some compounds was also evaluated to get insight into the structure–anticancer activity relationship of the 2- pyrazoline derivatives.

Synthesis, characterization, and antimicrobial evaluation of polyvinylalcohol-osthol composite films
Although poly-vinyl alcohol (PVA) has certain mechanical drawbacks such as a weak barrier, it has widely been used in food packaging over the last many years. To increase the suitability of PVA (C2H4O)n and render it ideal for food packaging, a diversity of studies have already been carried out. In the below-mentioned script, we, for the first time, report the use of natural product osthol in making a new composite with PVA for enhancing thermal, physicochemical, and antimicrobial properties.

The species belonging to the Lamiaceae family have been useful tools for many years as a folk remedy. In the present study, a microemulsion system was developed with extract of Scutellaria salviifolia Benth (endemic), Sideritis libanotica Labill. subsp. linearis (Bentham) Bornm (endemic), and Ziziphora clinopodioides Lam. Both and related microemulsion formulations were also investigated for their potential biological activities.

Hydnophytum formicarum is a medicinal plant that has a variety of bioactive compounds and has been traditionally used for therapeutic purposes. Hydnophytum formicarum grows on the stems of large trees and in a symbiosis with a type of ants. This study investigates the effects of technological factors on the extraction process of Hydnophytum formicarum in n-hexan, ethyl acetate, and ethanol solvents by using the Soxhlet method.

In this study we extracted bioactive ingredients from fruiting bodies of Laetiporus sulphureus with different solvents and tested the antimicrobial and antitumor activities. The predominant lipid composition of the fruiting bodies was studied with GC–MS and revealed a high amount of oleic acid, octadecenoic acid and ergosterol derivatives.

Around 200 different lipopeptides (LPs) have been identified to date, most of which are produced via Bacillus and Pseudomonas species. The clinical nature of the lipopeptide (LP) has led to a big surge in its research. They show antimicrobial and antitumor activities due to which mass-scale production and purification of LPs are beneficial. Response surface methodology (RSM) approach has emerged as an alternative in the field of computational biology for optimizing the reaction parameters using statistical models. In the present study, Pseudomonas sp.

A new class of 2-[4-(1H-benzimidazol-1-yl)phenyl]-1H-benzimidazoles (13–22) were synthesized via cyclocondensation reaction of the substituted 1,2-phenylenediamines (1,4–12) and 1-(4-formylpheny)-1H-benzimidazole (3). The synthesized compounds were evaluated for antibacterial and antifungal activities against S. aureus, methicillinresistant Staphylococcus aureus (MRSA), and Candida albicans by the tube dilution method. Compounds 13, 15, 18, 20, and 21 have moderate antifungal activity against C. albicans.

A new, less expensive, solvent-free procedure was developed for the synthesis of some new derivatives of various fused heterocyclic ring systems, namely azolopyridazine, azolotriazine, azinotriazine, thienopyridine, and pyrazolopyridine. The structures of the products prepared were established by their spectral data and elemental analyses. Eight compounds were evaluated for their in vitro antimicrobial activity. Some of the tested compounds exhibited moderate to significant antibacterial and antifungal activities.
