This work investigates the antimicrobial activity of the Schinus molle L. leaves extracts obtained under supercritical conditions using carbon dioxide and co-solvents. Antimicrobial qualitative evaluation was carried out through the bioautography technique and the microorganisms studied were Staphylococcus aureus, Pseudomonas aeruginosas, Escherichia coli, Micrococcus luteus, and Salmonella choleraesuis. The supercritical fluid extraction was carried out in a pilot
Aiming to target vitamin D receptors (VDR) expressed in melanoma cells, vitamin D 3 functionalized hybrid lipid-polymer nanoparticles (HNP-VDs) comprising a poly(lactic-co-glycolic acid) (PLGA) core and a lipid shell composed of hydrogenated soy phosphatidylcholine (HSPC), cholesterol (CHOL) and 1,2-disteroyl-sn-glycero-3-phosphaethanolamine-N[succinyl(polyethyleneglycol)-2000 (DSPE-PEG 2000 ) were synthesized. The nanocarriers were optimized to a lipid surface area coverage of 97%. In vitro drug release studies showed an initial burst release in the first 24 h followed by diffusive transport. Finally, cellular uptake experiments demonstrated that the HNP-VDs efficiently targeted B16 melanoma cells, thus resulting in a promising vehicle to deliver therapeutics for the melanoma treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
