Encapsulation of paclitaxel into a bio-nanocomposite. a study combining inelastic neutron scattering to thermal analysis and infrared spectroscopy

The anticancer drug paclitaxel was encapsulated into a bio-nanocomposite formed by magnetic nanoparticles, chitosan and apatite. The aim of this drug carrier is to provide a new perspective against breast cancer. The dynamics of the pure and encapsulated drug were investigated in order to verify possible molecular changes caused by the encapsulation, as well as to follow which interactions may occur between paclitaxel and the composite. Fourier transformed infrared spectroscopy, thermal analysis, inelastic and quasi-elastic neutron scattering experiments were performed. These very preliminary results suggest the successful encapsulation of the drug.

Molecular structures, electrochemical and spectroscopical properties of dichlorodicarbonylbis(tripenylphosphine)ruthenium(II) and dichlorodicarbonylbis(triphenylarsine)ruthenium(II)

The cct isomers [RuCl 2(CO) 2(PPh 3) 2] (1) and [RuCl 2(CO) 2(AsPh 3) 2] (2) were synthesized from [RuCl 3(PPh 3) 2DMA]DMA and [RuCl 3(AsPh 3) 2DMA]DMA, respectively. The complexes were characterized by elemental analysis, IR and UV-vis spectroscopy and their molecular structures were found to be cis-cis-trans isomers by X-ray crystallography. Cyclic voltammetry data show that the tripenylphosphine stabilizes better the ruthernium(II) complex than the tripenylarsine ligand. © 1994.

Vibrational and rotational spectroscopy of (CD3OD)-C-13

We have used Fourier Transform spectral data on the C-O stretching mode of (CD3OD)-C-13 in order to perform a vibro-rotational analysis for this molecule. We have estimated a few molecular parameters of the ground and C-O stretching vibrational modes. Based on these parameters, and by using the Kwan-Dennison model, we propose assignments for a number of far-infrared laser transitions of (CD3OD)-C-13.
