Synthesis and antiprotozoal activity of furanchalcone–quinoline, furanchalcone–chromone and furanchalcone–imidazole hybrids
(Springer Verlag, 2018)
We report herein the synthesis and biological activities (cytotoxicity, leishmanicidal, and trypanocidal) of several furanchalcone–quinoline, furanchalcone–chromone, and furanchalcone–imidazole hybrids. The synthesized ...
Synthesis of second-generation self-assembling Gemini Amphiphilic Pseudopeptides
(Elsevier, 2019-12-28)
Hypothesis
The structural modularity of Gemini Amphiphilic Pseudopeptides (GAPs) allows the tuning of the self-assembling properties by slight modifications in the chemical structures. We hypothesized that the introduction ...
Development of a glass-ceramic glaze formulated from industrial residues to improve the mechanical properties of the porcelain stoneware tiles
(Elsevier, 2018)
In this research a mixture of 90%wt of industrial residues (recycled soda-lime glass and ashes from a coalpower thermal plant) have been vitrified for their use as ‘‘secondary raw material”. Then, a glaze suspen-sion was ...
Sizing Down a Supramolecular Gel into Micro- and Nanoparticles
(American Chemical Society, 2017)
A low molecular weight gelator with a fluorescent 1,8-
naphthalimide unit forms micro- and nanoparticles in aqueous media. Slow
addition of a DMSO solution of the gelator into water affords either a selfassembled
fibrillar ...
Lung tumorspheres as a drug screening platform against cancer stem cells
(Oxford University Press (OUP), 2019-04)
Treatment resistance and metastasis are linked to cancer stem cells (CSCs). This population represents a promising target, but remains unexplored in lung cancer. The main objective of this study was to characterize lung ...
Influence of nanoparticle morphology and its dispersion ability regarding thermal properties of water used as phase change material
(2018-01-05)
Nanoparticles with different morphologies were added to water to study if the morphology of the nanoparticles affects the main parameters of water used as phase change material (PCM). Considered morphologies were spherical, ...
Effects on tubulin polymerization and down-regulation of c-Myc, hTERT and VEGF genes by colchicine haloacetyl and haloaroyl derivatives
(Elsevier, 2018-04-25)
Several colchicine analogues in which the N-acetyl residue has been replaced by haloacetyl, cyclohexylacetyl, phenylacetyl and various aroyl moieties have been synthesized. The cytotoxic activities of the synthesized ...
Atmosphere- and Voltage-Dependent Electronic Conductivity of Oxide-Ion-Conducting Zr1-xYxO2-x/2 Ceramics
(ACS, 2017-05)
Cubic, fluorite-structured solid solutions Zr1-xYxO2-x/2 (YSZ; x = 0.4-0.7) were prepared by sol-gel synthesis. Impedance measurements on pellets of 85% approximate density sintered at 1300 °C for 24 h showed strong evidence ...
A cost-effective combination of Rose Bengal and off-the-shelf cationicpolystyrene for the photodynamic inactivation ofPseudomonas aeruginosa
(Elsevier, 2020)
Two new photoactive materials have been prepared, characterized and tested againstPseudomonas aeruginosabacteria (planktonic suspension). The synthesis of the polymeric photosensitizers can be made at a multigramscale, in ...
Synthesis and Antiproliferative Activity of 3 and 7-Styrylcoumarins
(Springer Verlag, 2018)
A series of styrylcoumarins were obtained via Mizoroki-Heck reactions between 3-bromo-4-methyl7-(octyloxy)-2H-chromen-2-one
or 2-oxo-2H-chromen-7-yl trifluoromethanesulfonate and
functionalized styrenes. The structures ...
