Squalene in Nanoparticles Improves Antiproliferative Effect on Human Colon Carcinoma Cells Through Apoptosis by Disturbances in Redox Balance.

Squalene, a triterpene found in extra virgin olive oil, has therapeutic properties in diseases related to oxidative stress, such as cancer. However, its hydrophobic nature and susceptibility to oxidation limit its bioavailability outside of olive oil. To expand its applications, alternative delivery methods are necessary.

Gold(I) Complexes Based on Nonsteroidal Anti-Inflammatory Derivatives as Multi-Target Drugs against Colon Cancer.

Targeting inflammation and the molecules involved in the inflammatory process could be an effective cancer prevention and therapy strategy. Therefore, the use of anti-inflammatory strategies, such as NSAIDs and metal-based drugs, has become a promising approach for preventing and treating cancer by targeting multiple pathways involved in tumor progression. The present work describes new phosphane gold(I) complexes derived from nonsteroidal anti-inflammatory drugs as multitarget drugs against colon cancer.

Biological Properties of Extract on Caco-2 Cells: Antioxidant, Anticancer, and Anti-Inflammatory Effects.

(BE) is a mushroom well known for its taste, nutritional value, and medicinal properties. The objective of this work was to study the biological effects of BE extracts on human colon carcinoma cells (Caco-2), evaluating parameters related to oxidative stress and inflammation. In this study, a hydroethanolic extract of BE was obtained by ohmic heating green technology.

DNA Interactions and Biological Activity of 2,9-Disubstituted 1,10-Phenanthroline Thiosemicarbazone-Based Ligands and a 4-Phenylthiazole Derivative.

Four 1,10-phenanthroline derivatives (-) were synthesized as potential telomeric DNA binders, three substituted in their chains with thiosemicarbazones (TSCs) and one 4-phenylthiazole derivative. The compounds were characterized using NMR, HRMS, FTIR-spectroscopy and combustion elemental analysis. Quadruplex and dsDNA interactions were preliminarily studied, especially for neutral derivative , using FRET-based DNA melting assays, equilibrium dialysis (both competitive and non-competitive), circular dichroism and viscosity titrations.
