A highly functionalized aminoacyl nucleolipid based on uridine is here proposed as a novel cationic surfactant. To achieve this, a straightforward, high yielding and versatile protocol has been devised, in principle providing synthetic access to a variety of different, related analogs. Self-aggregation properties of this nucleolipid were determined by using a combined approach, including surface tension, conductivity and DLS measurements. Above the critical micellar concentration of 4 x 10(-5) mol kg(-1), large supramolecular assemblies with a counterion condensation degree of 0.25 were observed. The bioactivity profile of this new compound was investigated on cancer and non cancer cell lines. (C) 2012 Elsevier Masson SAS. All rights reserved.
