Cationic lipids nowadays constitute a promising alternative to recombinant
viruses for gene transfer. We have recently explored the transfection potential
of a new class of lipids based upon the use of aminoglycosides as cationic polar
headgroups. The encouraging results obtained with a first cholesterol derivative
of kanamycin A prompted us to investigate this family of vectors further, by
modulating the constituent structural units of the cationic lipid. For this
study, we have investigated the transfection properties of a series of new
derivatives based on a kanamycin A scaffold. The results primarily confirm that
aminoglycoside-based lipids are efficient vectors for gene transfection both in
vitro and in vivo (mouse airways). Furthermore, a combination of transfection and
physicochemical data revealed that some modifications of the constitutive
subunits of kanamycin A-based vectors were associated with substantial changes in
their transfection properties.
