Spontaneous catanionic vesicles formed by the interaction between an anionic β-cyclodextrins derivative and a cationic surfactant

Abstract

Catanionic vesicles containing an anionic β-cyclodextrins derivative and a cationic surfactant.

Cyclodextrin modified niosomes to encapsulate hydrophilic compounds

“…Mod-b-CD was synthetized in the laboratory as was previously described. 38,39 Chloroform and methanol (HPLC quality) were obtained by J. T. Baker. Milli Q water was used in all experiments.…”

“…Thus, the interaction of the active compounds with the CDs loaded niosomes could be different. Mod-b-CD has been synthetized and studied in our laboratory 38,39 and it was demonstrated that it can form aggregates in aqueous and organic media, and in both systems, the cavity is available to interact with external guests. [40][41][42] It is worth to mention that all the molecules used in this work for the synthesis of the carriers are fatty acids and sugar derivated.…”

Base-triggerable lauryl sarcosinate–dodecyl sulfate catanionic liposomes: structure, biophysical characterization, and drug entrapment/release studies

“…11,12 To date, various types of cationic and anionic surfactants or lipids have been used to make catanionic vesicles. [13][14][15][16][17][18][19][20][21] The spontaneous formation, higher colloidal stability, and versatility in the charge and size of catanionic vesicles have made them attractive candidates over conventional liposomes for drug delivery applications. 15,[22][23][24][25] Over the last decade or so, researchers have been attracted to amino acid based surfactants for the design of stable catanionic vesicles due to their good surface properties, versatile self-assembly, and simple synthesis.…”

In initial work in this direction, we have reported the preparation and characterization of catanionic vesicles made up of alkyl esters of glycine/alanine and the anionic surfactant sodium dodecyl sulfate.…”
