Vesicle formation by amphiphilic 10-alkyl-3-methyl isoalloxazine in aqueous medium.

ABSTRACT

The synthetic 10-alkyl isoalloxazines have been found to form vesicles in aqueous and binary solvent systems and confirmed by UV-visible, fluorescence,transmission electron microscopy and quasi elastic light scattering experiments. The mean external diameters of vesicles have been calculated for isoalloxazine with different carbon atom chain at position 10 by transmission electron microscopy and quasi elastic laser light scattering. The gel to liquid phase transition of liposomes measured by differential scanning calorimetry shows reproducible endothermic peak which lies well in the range of typical aqueous vesicles.
