Dimiristoylphosphatidylcholine/genistein molecular interactions: A physico-chemical approach to anti-glioma drug delivery systems.

Regarding free genistein small delivery to the central nervous system, physico-chemical parameters of dimiristoylphosphatidylcholine liposome-loaded genistein were investigated, as well as its in vitro activity against the DPPH radical and glioma cells. Data obtained by UV-vis spectroscopy, Fourier Transform Infrared Spectroscopy, Nuclear Magnetic Resonance, Differential Scanning Calorimetry and Dynamic Light Scattering were used to characterize the liposomal system with respect to motion restriction, hydration degree, trans-gauche isomerization and phase state. In vitro antitumoral effects were monitored through conting and viability assays.
