Semisynthetic Phenol Derivatives Obtained from Natural Phenols: Antimicrobial Activity and Molecular Properties.

Journal of agricultural and food chemistry
Semisynthetic phenol derivatives were obtained from the natural phenols: thymol, carvacrol, eugenol, and guaiacol through catalytic oxychlorination, Williamson synthesis, and aromatic Claisen rearrangement. The compounds characterization was carried ...

Baicalin inhibits Escherichia coli isolates in bovine mastitic milk and reduces antimicrobial resistance.

Journal of dairy science
In this study, we aimed to evaluate the inhibitory effect of baicalin on Escherichia coli in vitro and the effects of baicalin treatment on antimicrobial resistance of the E. coli isolates. Through isolation, purification, and identification, a total...

Synthesis and Evaluation of Biological Activities of Aziridine Derivatives of Urea and Thiourea.

Molecules (Basel, Switzerland)
In the present paper, we report the synthesis and evaluation of in vitro antimicrobial activities of aziridine-thiourea derivatives. A series of aziridines in reaction with isocyanates and isothiocyanates to obtain urea and thiourea derivatives were ...

Antibacterial activity of selenium-enriched lactic acid bacteria against common food-borne pathogens in vitro.

Journal of dairy science
Selenium (Se) is an essential trace element for human health and animal nutrition. The aim of this study was to evaluate the inhibitory activities of Se-enriched lactic acid bacteria (LAB), Lactobacillus delbrueckii ssp. bulgaricus and Streptococcus ...

Antimicrobial Furoquinoline Alkaloids from Vepris lecomteana (Pierre) Cheek & T. Heller (Rutaceae).

Molecules (Basel, Switzerland)
Three new prenylated furoquinoline alkaloids named lecomtequinoline A (), B (), and C (), together with the known compounds anhydroevoxine (), evoxine (), dictamnine (), methylflindersine (), evoxanthine (), hesperidin, lupeol, -sitosterol, stigmaste...

Antibacterial mechanisms of a novel type picosecond laser-generated silver-titanium nanoparticles and their toxicity to human cells.

International journal of nanomedicine
In this study, we explored the antibacterial mechanisms for a novel type of Ag-TiO compound nanoparticles (NPs) produced from an Ag-TiO alloy using a picosecond laser and evaluated the toxicity of the Ag-TiO NPs to a range of human cell types. Transm...

Nitric oxide-releasing injectable hydrogels with high antibacterial activity through in situ formation of peroxynitrite.

Acta biomaterialia
UNLABELLED: Nitric oxide (NO) is an endogenous molecule with many critical biological functions that depend on its concentration. At high levels, NO provides broad-spectrum antibacterial effects through both its pathogen inhibition and killing abilit...

Aptamer facilitated purification of functional proteins.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences
DNA aptamers are attractive capture probes for affinity chromatography since, in contrast to antibodies, they can be chemically synthesized and, in contrast to tag-specific capture probes (such as Nickel-NTA or Glutathione), they can be used for puri...

Preservative effect of Camellia sinensis (L.) Kuntze seed extract in soy sauce and its mutagenicity.

Food research international (Ottawa, Ont.)
The purpose of this study was to investigate the applicability of green tea seed (GTS) extract as a natural preservative in food. Food preservative ability and mutagenicity studies of GTS extract and identification of antimicrobial compounds from GTS...
