Abstract
Bile salts are biosurfactants that can induce structure transformations in supramolecular nanoassemblies with conventional surfactants owing to their unique, planar amphiphilic character and the rigidity of their hydrophobic steroid skeleton. However, structural information about the association of bile salts and amphiphilic glycosides is lacking. In this work, we investigated the micelle structure of two anionic di- and trihydroxy bile salts [sodium deoxycholate (SDC) and sodium cholate (SC)] and a conventional anionic surfactant [sodium dodecyl sulfate (SDS)] in mixtures with a nonionic steviol glycoside [α-glucosyl stevia (Stevia-G)] and studied their potential as a nanocarrier system for two poorly water-soluble drugs (clotrimazole and ketoconazole). Decreased critical micelle concentrations determined from surface tension measurements demonstrate synergistic interactions between Stevia-G and SDS/SDC/SC in a decreasing order. Small-angle X-ray and neutron scattering, interpreted by a core-shell ellipsoid model, indicate that SDS and bile salts act differently on the mixed micelle structure. Compared with SDS/Stevia-G, bile salt/Stevia-G had a core-shell structure more similar to that of pure Stevia-G micelles. SDC and SDS had an increasing and decreasing influence, respectively, on the available molecular surface area in mixtures with Stevia-G on the micelle core but a similar influence on the micelle shell solvation number relative to that of their pure micellar structures. The number of bile salt hydroxyl groups was influential in determining the micelle stoichiometry: an increasing number of hydroxyl groups corresponded to decreasing bile salt aggregation numbers and a smaller hydrophobic micellar core. The core volume was the most important structural factor in explaining the drug solubilization capacity of the nanocarrier systems. Therefore, bile salt-steviol glycoside mixed micellar assemblies exhibit structure control mechanisms allowing the fine-tuning of their interior hydrophobic domains important for nanocarrier applications toward solubilization of poorly water-soluble drugs.

Abstract
Background Curcumin (CUR) is a functional ingredient from the spice turmeric. It has attracted considerable attention recently, owing to its diverse biological activities. However, curcumin has low water solubility, which limited its applications. Some sugar molecules were found to be able to solubilise poorly water-soluble compounds by forming micelles in aqueous solutions. Purpose To improve the water solubility and oral absorption of CUR, using a non-nutritive natural sweetener, namely, Mogroside V (Mog-V). Methods A solid dispersion of CUR in Mog-V was prepared using a solvent evaporation method. The solid dispersion was characterised by using X-ray diffraction and differential scanning calorimetry. The solid dispersion can dissolve in water to form micelles with a diameter of ~160 nm, which were characterised by using dynamic light scattering. To find out the mechanism of solubilisation, the aggregation behaviour of Mog-V molecules in aqueous solution was investigated using nuclear magnetic resonance spectroscopy. Finally, oral absorption of CUR in the solid dispersion was evaluated using a rodent model. Results A solid dispersion was formed in a ratio of 1 CUR to 10 Mog-V by weight. Upon dissolution into water, CUR laden micelles formed via self-assembly of Mog-V molecules, which increased the solubility of CUR by nearly 6000 times compared with pure CUR crystals. In rats, the solid dispersion increased the oral absorption of CUR by 29 folds, compared with CUR crystals. In terms of solubilisation mechanism, it was found that Mog-V self-assembled into micelles with a core-shell structure and CUR molecules were incorporated into the hydrophobic core of the Mog-V micelles. Conclusion Mog-V can form a solid dispersion with CUR. Upon dissolution in water, the Mog-V in the solid dispersion can self-assemble into micelles, which solubilise CUR and increase its oral absorption.

Abstract
Transglycosylation has been used to modify the physicochemical properties of original compounds. As a result, transglycosylated compounds can form molecular aggregates in size ranges of a few nanometers in an aqueous medium when their concentrations exceed a specific level. Incorporating these hydrophobic compounds has been observed to enhance the solubility of hydrophobic compounds into aggregate structures. Thus, this review introduces four transglycosylated compounds as food additives that can enhance the solubility and oral absorption of hydrophobic compounds. Here, transglycosylated hesperidin, transglycosylated rutin, transglycosylated naringin, and transglycosylated stevia are the focus as representative substances. Significantly, we observed that amorphous formations containing hydrophobic compounds with transglycosylated compounds improved solubility and oral absorption compared to untreated hydrophobic compounds. Moreover, combining transglycosylated compounds with hydrophilic polymers or surfactants enhanced the solubilizing effects on hydrophobic compounds. Furthermore, the enhanced solubility of hydrophobic compounds improved their oral absorption. Transglycosylated compounds also influenced nanoparticle preparation of hydrophobic compounds as a dispersant. This study demonstrated the benefits of transglycosylated compounds in developing supplements and nutraceuticals of hydrophobic compounds with poor aqueous solubility.

Abstract
The poor water solubility of rebamipide was enhanced by the mixed micelles of transglycosylated stevia (Stevia-G) and trimethylammonium chloride with varying carbon chain length (C nTAC, n = 14, 16, and 18). Fluorometry, isothermal titration calorimetry (ITC) and dynamic light scattering techniques examined the aggregation properties of Stevia-G and C nTAC. Synergism was found between Stevia-G and C nTAC using the approaches of Clint and Rubingh. The negative interaction parameter (average βm = -4.17, -5.47, and -7.07) and excess free energy (average ΔG°ex = -2.47, -3.06, and -3.88 kJ mol-1) increased with increasing chain length of C nTAC. The negative B1 values by the Maeda approach suggested that chain-chain interactions contribute to the formation of a mixed micelle. The solubilization of rebamipide in the mixed micelle was evaluated in the term of the molar solubilization ratio (MSR) and partition coefficient ( Km). The Km from the Stevia-G/C16TAC system was highest at a low mole fraction of C nTAC (0.2-0.6). In conclusion, the solubilization of rebamipide was more favorable between Stevia-G and C16TAC, although the stability of the mixed micelle was enhanced by an increase in hydrophobicity of the longer chain lengths used in C nTAC.
