Impact of Zero-Valent Iron Nanoparticles and Ampicillin on Adenosine Triphosphate and Lactate Metabolism in the Cyanobacterium .

In cyanobacteria, the interplay of ATP and lactate dynamics underpins cellular energetics; their pronounced shifts in response to zero-valent iron (nZVI) nanoparticles and ampicillin highlight the nuanced metabolic adaptations to environmental challenges. In this study, we investigated the impact of nZVIs and ampicillin on cellular energetics as determined by adenosine triphosphate (ATP) content, intracellular and extracellular lactate levels, and their impact on cell morphology as visualized by transmission electron microscopy. While a significant increase in ATP concentration was observed in 0.

Antibiotic-Induced Changes in Pigment Accumulation, Photosystem II, and Membrane Permeability in a Model Cyanobacterium.

is a well-studied a model cyanobacterium for photosynthesis due to its efficient light absorption potential and pigment accumulation. In the present study, the impact of ampicillin, tetracycline, kanamycin, and cefotaxime on pigment fluorescence and photosynthetic capacity in strains B481-WT and B481-SD was investigated. Our results indicated that both strains exposed to kanamycin from 0.

Design, synthesis and biological evaluation of novel bischalcone derivatives as potential anticancer agents.

Building on our previous work that discovered chalcone as a promising pharmacophore for anticancer activity, we have various other chalcone derivatives and have synthesized a series of novel bischalcone to explore their anticancer activity. Among all tested compounds, compounds 6a, 6b, and 6c showed the highest antiproliferative activity against A-549 cancer cell lines with the average IC values of 4.18, 4.
