Abstract

Flurbiprofen-nicotinamide solid dispersions were prepared by the fusion method. The solid dispersions were evaluated for dissolution rate. The drug-carrier interaction in the liquid and solid states were studied by using phase solubility analysis, phase diagram, X-ray diffraction (XRD), and differential scanning calorimentry (DSC). Solid dispersions gave fast and rapid dissolution of flurbiprofen compared with the pure drug and the physical mixture. Phase diagram and DSC indicated that flurbiprofen and nicotinamide form a eutectic mixture. The aqueous solubility of flurbiprofen was enhanced in the presence of nicotinamide.

Relationship between blood compatibility and water structure--comparative study between 2-methoxyethylacrylate- and 2-methoxyethylmethacrylate-based random copolymers.

We have proposed that the excellent blood compatibility of poly(2-methoxyethylacrylate (MEA)) is caused by freezing bound water contained in it on the basis of results on platelet activation (Tanaka and Mochizuki, J Biomed Mater Res A 2004; 68:684-695). To clarify the applicability of this mechanism to other indexes for blood compatibility, the relationship between complement activation and water structure was investigated by using two copolymers, poly(MEA-2-hydroxyethylmethacrylate (HEMA)) and poly(2-methoxyethylmethacrylate (MEMA)-HEMA), where HEMA content was varied from 25 to 90 mol %. ESCA analysis revealed that the surface compositions of these copolymers (dry state) agreed with the compositions determined by (1)H NMR. However, analysis by water contact angle (wet state) showed that their surfaces were quite different. The contact angle of poly(MEMA-HEMA) depended on the monomer composition, whereas the angle of poly(MEA-HEMA) was close to that of polyHEMA regardless of the monomer composition. The effect of HEMA content in the copolymers on complement activation (production of C3a) was investigated in an in vitro test. The activation by poly(MEMA-HEMA) was enhanced according to the HEMA content, while the activation by poly(MEA-HEMA) with 0-40 mol % of HEMA was weak and did not depend on the HEMA content. These properties are discussed from the viewpoints of the water structure observed by DSC and the surface structure.

Shape dependence in the formation of condensed phases exhibited by disubstituted sucrose esters.

We report on the self-organizing properties of sucrose esters that are di-(1',6', 1',6, and 6,6')-substituted with aliphatic chains of identical or different chain lengths and levels of saturation. For the materials possessing two saturated aliphatic chains, the compounds exhibited thermotropic lamellar smectic A phases. A remarkable new phase transition was observed for the di-octadecanoyl homologue in which one smectic A phase transformed into another with a continuous change in layer spacing, but with a discontinuous change in the correlation length. The incorporation of long cis-unsaturated chains led to increased cross-sectional areas of the chains relative to the sucrose head groups and, hence, columnar phases were observed.

Photoluminescence and conductivity of self-assembled pi-pi stacks of perylene bisimide dyes.

The self-assembly of a new, highly fluorescent perylene bisimide dye 2 into pi stacks, both in solution and condensed phase, has been studied in detail by NMR spectroscopy, vapor pressure osmometry (VPO), UV/Vis and fluorescence spectroscopy, differential scanning calorimetry (DSC), optical polarizing microscopy (OPM) and X-ray diffraction. The NMR and VPO measurements revealed the formation of extended pi-pi stacks of the dye molecules in solution. The aggregate size determined from VPO and DOSY NMR measurements agree well with that obtained from the concentration and temperature-dependent UV/Vis spectral data by employing the isodesmic model (equal K model). In the condensed state, dye 2 possesses a hexagonal columnar liquid crystalline (LC) phase as confirmed by X-ray diffraction analysis. The columnar stacking of this dye has been further explored by atomic force microscopy (AFM). Well-resolved columnar nanostructures of the compound are observed on graphite surface. A color-tunable luminescence from green to red has been observed upon aggregation which is accompanied by an increase of the fluorescence lifetime and depolarization. The observed absorption properties can be explained in terms of molecular exciton theory. The charge transport properties of dye 2 have been investigated by pulse radiolysis-time resolved microwave conductivity measurements and a 1D charge carrier mobility up to 0.42 cm(2) V(-1) s(-1) is obtained. Considering the promising self-assembly, semiconducting, and luminescence properties of this dye, it might serve as a useful functional material for nano(opto)electronics.
