Abstract: | A new series of perfluoroalkylated fatty acid monoesters of α,α-trehalose and sucrose has been evaluated with respect to their
physicochemical and biological properties for possible biomedical use. These water-soluble compounds strongly reduce the water
surface tension and fluorocarbon/water interfacial tension. As co-surfactants in perfluorodecalin/Pluronic F-68 type emulsions
they significantly increase the stability of these emulsions. Remarkably stable concentrated perfluorodecalin-in-water (50%
w/v) emulsions were obtained when the C8F17CH2CH2C(O)-α,α-trehalose monoester was used as the sole surfactant, while no emulsion could be obtained with its maltoside analogue.
No significant effect on the growth and viability of Namalva cell cultures and no hemolytic activity on human erythrocytes
at concentrations up to 50 g/L were detected for these amphiphiles in spite of their high surface activity. The LD50 was found to be in the range of 250–375 mg/kg of body weighti.v. in mice. |
