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

Chemistry &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.

Peptide Arginases from Cryptic Pathways Install Ornithine Residues in Uncharacterized Members of Orphan RiPP Families

ChemBioChem, EarlyView.
The incorporation of the non‐proteinogenic amino acid ornithine into antibiotic peptides has shown potential in influencing antibacterial efficacy. Novel peptide arginases from cryptic ribosomally synthesized and post‐translationally modified peptide (RiPP) pathways are identified and found to incorporate ornithine residues into various peptide ...

Future Perspective On Materials, Electrochemistry, and Cell Concepts for Redox‐Mediated CO2 Direct Air Capture Scenarios

ChemistryEurope, EarlyView.
Direct air capture (DAC) of carbon dioxide (CO2) emerges as a key strategy for climate crisis mitigation. Redox‐mediated electrochemical carbon capture offers a promising route for energy‐efficient DAC. This perspective discusses recent advances in the field, highlighting key challenges, such as oxygen interference at low CO2 concentrations, and ...

Investigating Metal and Fluorophore Controlled Intracellular Localization in Noble Metal Thiosemicarbazone Complexes

Chemistry – A European Journal, EarlyView.
Same ligand, same dye, different metal: Thiosemicarbazone conjugates of Pt and Pd show distinctly different localization patterns inside mammalian cells. Abstract Transition metal complexes have been widely utilized as cellular imaging tools. To impart organelle specificity, ligand architecture is usually modified to modulate properties like overall ...
