Hypothesis: Amino acid-based surfactants have been proposed as skin permeation enhancers. In this work, we investigated the potentiality of two arginine-based amphiphiles as permeation enhancers by studying their interaction with stratum corneum (SC) model lipid membranes. Experiments: Na-benzoyl arginine decyl- and dodecylamide were tested in com...

Vitamin D exerts pleiotropic effects in the body, mainly in the mineral homeostasis as well as extra-skeletal actions. Deficiency of vitamin D is very frequent and its supplementation might be needed. In this work, a novel nanocarrier for vitamin D3 based on polymersomes is developed. The polymersomes were prepared by self-assembly of previously sy...

Cationic amino acid-based surfactants are known to interact with the lipid bilayer of microorganism resulting in cell death through a disruption of the membrane topology. To elucidate the interaction of a cationic surfactant synthesized in our lab, investigations involving Nα-benzoyl-arginine decyl amide (Bz-Arg-NHC10), and model membranes composed...
Article
The strong UV absorption of the bromide in aqueous solution undergoes a remarkable red shift of more than 10 nm induced by the addition of the salts that constitute a saline buffer. The maximum absorption wavelength of the bromide is displaced from approximately 194 nm in ultrapure water to wavelengths above 200 nm, depending on the composition of...

A novel arginine-based cationic surfactant Nα-benzoyl-arginine dodecylamide (Bz-Arg-NHC12) was synthesized in our laboratory. In this paper we study the interaction of Bz-Arg-NHC12 with sheep and human red blood cells (SRBC and HRBC respectively) due to their different membrane physicochemical/biophysical properties. SRBC demonstrated to be slightl...

Two novel arginine-based surfactants, Bz-Arg-NHC10 and Bz-Arg-NHC12, were characterized with respect to surface properties and their interaction with human red-blood-cell (HRBC) membranes. The values for critical micellar concentration (CMC), the maximum surfactant adsorption at the air–liquid interface, and the area per molecule indicated better s...
