Potential tuberculostatic agent: Micelle-forming pyrazinamide prodrug
Pyrazinamide was condensed with the poly(ethylene glycol)-poly(aspartic acid) copolymer (PEG-PASP), a micelle-forming derivative was obtained that was characterized in terms of its critical micelle concentration (CMC) and ...
Preparation of polymeric micelles for use as carriers of tuberculostatic drugs
(Pharmacotherapy Group, 2014)
The hydration of sodium dehydrocholate micelles
The hydration of micellised sodium dehydrocholate molecules was determined by viscosity measurements. It was found that there are 39 water molecules for each micellised surfactant molecule. About ten water molecules may ...
Experimental and thermodynamic analysis of mixed micelles formed by dodecylethylmethacrylatedimethylammonium bromide and tetradecyltrimethylammonium bromide
(Elsevier Science, 2021-04-05)
The micellization process of a surfactant system formed by the mixture of two cationic surfactants, a conventional one, tetradecyltrimethylammonium bromide (TTAB), and a polymerizable surfactant, methylammonium ...
SELF-ASSEMBLY OF TRIBLOCK COPOLYMERS IN AQUEOUS SOLUTION
(Sociedad Chilena de Química, 2008)
Are the mixtures of homologous surfactants ideal?
(Academic Press Inc Elsevier Science, 2006-11)
The interaction between homologous surfactants in mixed micelles was studied by the Regular Solution Theory of mixed micelles. The interaction is independent of the nature of the polar head groups and attractive and the ...
Interaction of sodium cholate with dioctadecyldimethylammonium chloride vesicles in aqueous dispersion
(Elsevier B.V., 2006-11-15)
Mixtures of dioctadecyldimethylammonium chloride (DODAC) cationic vesicle dispersions with aqueous micelle solutions of the anionic sodium cholate (NaC) were investigated by differential scanning calorimetry, DSC, turbidity ...
Interaction between anionic polyelectrolytes and CTAB micelles. A potentiometric study
The interaction between a series of anionic copolymers having variable hydrophobic character with cationic micelles of cetyltrimethylammonium bromide (CTAB) has been studied by measuring the free bromide ion concentration. ...
Monitoring the microenvironment inside polymeric micelles using the fluorescence probe 6-propionyl-2-dimethylaminonaphthalene (PRODAN)
(Elsevier Science, 2021-12)
6-propionyl-2-dimethylaminonaphthalene (PRODAN) is a fluorescent molecule with sensitivity to environmental polarity and hydrogen bond interactions. Although it has been extensively used to study organized systems such as ...
