1. Synthesis and Evaluation of Antibacterial Activity of 1,2,3-Triazole and Ether Derivatives of Paeonol
Multi-drug-resistant bacteria (MDR) are the cause of different infections and diseases that have affected humanity for a long time, and have been an emerging global health problem that has led to increased morbidity and mortality. The growing emergence of MDR bacteria has underlined the need for development and discovery of new antibacterial compounds. In th

2. Monoglyceride biosynthesis from coconut milk with lypase enzyme of sesame seed sprouts as biocatalyst
Abstract Monoglycerides are oleochemical compounds that were widely used as emulsifying agents for foods, anti-bacterial and anti-viruses (monolaurin, monocaprin). The objective of this research was to study the optimal reaction conditions in monoglyceride production from coconut milk. To achieve that purpose, the research was carried out with two factors, n

6. A IMPORTÂNCIA DAS CUMARINAS PARA A QUÍMICA MEDICINAL E O DESENVOLVIMENTO DE COMPOSTOS BIOATIVOS NOS ÚLTIMOS ANOS
Coumarins are natural products characterized as 2H-chromen-2-one, according to IUPAC nomenclature, largely distributed in plants, as well as, in species of fungi and bacteria. Nowadays, many synthetic procedures allow the discovery of coumarins with expanded chemical space. The ability to exert non-covalent interactions with many enzymes and receptors in liv

8. Antibacterial Effects of Cuminum cyminum Extract Against Enterococcus Faecalis Biofilms From Clinical Isolates
Abstract Objective: To compare the antibacterial efficacy of Cuminum cyminum (cumin) extract and 2% chlorhexidine. Material and Methods: E. faecalis was isolated from non-vital teeth with chronic apical abscess. Samples were then bred in the ChromAgar medium. Subsequently, E. faecalis bacteria’s DNA extraction was performed. DNA was then amplified by con

9. In situ DEPOSITION OF COPPER NANOPARTICLES ON POLYETHYLENE TEREPHTHALATE FILTERS AND ANTIBACTERIAL TESTING AGAINST Escherichia coli AND Salmonella enterica
Abstract This study reports a synthesis of copper nanoparticles (CuNP) deposited on polyethylene terephthalate (PET) filters and antibacterial evaluation of the obtained filters against Escherichia coli and Salmonella enterica. CuNP were synthesized by a two-step method involving adsorption of [Cu(OH)4]2- ions onto a PET filter and subsequent chemical reduct

11. Amphotericin-B and vancomycin-loaded chitosan nanofiber for antifungal and antibacterial application
In the present study, a mucoadhesive non-woven fiber mat (d= 116 nm) was fabricated by the electrospinning method using chitosan (80% Wt), polyethylene oxide (10% Wt), cysteine (4% Wt) and drugs (6% Wt), respectively. In addition, a comparative study was conducted to define effect of drugs and mucoadhesive agent on the nanofiber formation. FTIR, SEM, DSC and
