Interaction and solubilization of some phenolic antioxidants in Pluronic® micelles

pH induced tuning of size, charge and viscoelastic behavior of aqueous micellar solution of Pluronic ® P104–anthranilic acid mixtures: A scattering, rheology and NMR study

“…The apparent hydrodynamic diameter (D h ) of P104 micelles is about 16 ± 3 nm [47] which is in agreement to our previous studies [34,48]. The apparent hydrodynamic diameters of P104 (1% 5% and 10%) micelles in the presence of various concentrations of AA are displayed in Fig.…”

“…The crosspeaks observed above and below the diagonals indicate through space interaction between those protons and hence confirm the association of AA with Pluronics. The cross peaks observed between all aromatic ring protons of AA (a-d) with proton methyl group (B 1 ) from PPO block and also with methylene protons of both blocks (PEO and PPO), indicating AA reside in core as well as core-corona interface of the micelles [34].…”

“…Gadelle et al [32] studied solubilization of aromatic solutes and found that solubilization depends on the structure of solute, EO/PO ratio, molecular weight of the polymer and concentration. Recently, our group also investigated solubilization of poorly water soluble aromatic hydrocarbons, acids, alcohol and drugs in Pluronic ® micelles [8,12,[33][34][35][36]. Verma et al [37] studied the pH-induced microstructural changes in cetyltrimethylammonium bromide (CTAB) micelles in the presence of AA and probed spherical globule to wormlike micellar transition by rheological and scattering measurements.…”

Production of stabilized quercetin aqueous suspensions by supercritical fluid extraction of emulsions

“…Furthermore it can promote the oxidation of Fe 2+ to Fe 3+ , which is less effective in generating free radicals. These effects of quercetin may be explained by its o-diphenol B-ring structure [2] and the ability of donating π electrons from the benzene ring, while it is remaining relatively stable [3]. It has also anti-proliferative effects in a wide range of human cancer cell lines [4].…”

Self-assembling systems based on quaternized derivatives of 1,4-diazabicyclo[2.2.2]octane in nutrient broth as antimicrobial agents and carriers for hydrophobic drugs

“…This drug is an anionic polyphenol possessing antioxidant and chelating properties [67]. In addition, quercetin is an effective anti-inflammatory, anti-tumor, and heart disease drug [68,69].…”
