First Report on some N2O2‐Donor Sets Tetradentate Schiff Base and Its Metal Complexes: Characterization and Antimicrobial Investigation

open access: yesChemistry &Biodiversity, EarlyView.
Mass spectrometry, UV‐Vis. spectra, thermal analysis and antimicrobial evaluation were done for a novel tetradentate Schiff base ligand (H2L) and its metal complexes. ABSTRACT The new Schiff base ligand N,N′‐thiophene‐(bis‐1‐ethyl‐6,8‐difluoro‐7‐(3‐methylpiperazin‐1‐yl)‐4‐oxo‐1,4‐dihydroquinoline‐3‐carboxylic acid) (H2L) was synthesized via ...

Co‐cultivation and Medium Optimization: A Strategy for Discovering Fungal‐derived Protease Inhibitors

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The fungi Fusarium guttiforme and Phytophthora palmivora were cultivated in four different media (Potato Dextrose Agar, Czapek, rice, and ISP2) and co‐cultured to stimulate fungal interactions and enhance secondary metabolite production. Promising extracts were fractionated, yielding compounds such as the iron complex of fusaric acid (1 ...

Impact of Species, Growth Conditions, and Plant Processing on the Phytochemistry and Antimicrobial Activity of Agrimonia Extracts

open access: yesChemistry &Biodiversity, EarlyView.
Agrimony is a medicinal herb known for its content of polyphenols and beneficial bioactivity, both of which can be strongly influenced by cultivation and processing. This study reveals that agrimony plant structures, species, and postharvest processing are the main drivers of observed variability in both phytochemical composition and antimicrobial ...

Chemodiversity of Essential Oils From Eugenia uniflora L. Collected in Different Phytophysiognomies of the Coastal Region of Rio de Janeiro

open access: yesChemistry &Biodiversity, EarlyView.
Essential oils from Eugenia uniflora collected in different coastal phytophysiognomies of Rio de Janeiro showed notable chemodiversity. GC‐MS and GC‐FID analyses revealed nine chemotypes, mainly rich in curzerene and selina‐1,3,7(11)‐trien‐8‐one. ABSTRACT This study aimed to evaluate the yield, color, and chemical composition of Eugenia uniflora ...

Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.
