Tellurium: an element with great biological potency and potential.
The close chemical relationship between tellurium and sulfur also transcends into in vitro and in vivo situations and provides new impetus for the development of enzyme inhibitors and redox modulators, some of which may be of interest in the field of antibiotics and anticancer drug design. Expand
Monitoring migration and transformation of nanomaterials in polymeric composites during accelerated aging
The incorporation of small amounts of nanoadditives in polymeric compounds can introduce new mechanical, physical, electrical, magnetic, thermal and/or optical properties. The properties of theseExpand
The natural organosulfur compound dipropyltetrasulfide prevents HOCl-induced systemic sclerosis in the mouse
The natural organosulfur compound DPTTS prevents skin and lung fibrosis in the mouse through the selective killing of diseased fibroblasts and its immunomodulating properties. Expand
Selenium- and tellurium-containing multifunctional redox agents as biochemical redox modulators with selective cytotoxicity.
To further improve selectivity, multifunctional sensor/effector agents are now required that recognize the biochemical signature of OS in target cells that provide interesting challenges for chemistry in the future. Expand
Selective antimicrobial activity associated with sulfur nanoparticles.
Together, the ease of production of the sulfur nanoparticles, their chemical stability in aqueous dispersion, amenable physical properties and selective toxicity, turn sulphur nanoparticles into promising antimicrobial prototypes for medical as well as agricultural applications. Expand
Influence of Nanomaterial Compatibilization Strategies on Polyamide Nanocomposites Properties and Nanomaterial Release during the Use Phase.
This study shows that optimal compatibilization between NM and matrix can improve NC performance, reducing polymer degradation and exposure and/or release of the nanofiller. Expand
Redox active secondary metabolites.
Together, these redox-modulating metabolites provide promising new leads to target selectively certain cancer cells and may also be useful in the treatment of autoinflammatory diseases. Expand
Chalcone-Coumarin derivatives as potential anti-cancer drugs: an in vitro and in vivo investigation.
Investigation of the structure-activity relationship of a variety of coumarin derivatives in terms of cytotoxicity towards human and murine carcinoma cell lines found the most potent cytotoxic effect on colon cancer cells, CT26, was linked to their pro-oxidant properties. Expand
Natural Sulfur Products as Redox Modulators and Selective Inducers of Cell Death
Numerous plants, fungi and microorganisms contain organic sulfur compounds (OSCs), which during the last couple of decades have been associated increasingly with chemoprevention, antibacterial andExpand
