Therapeutic perspectives of bone tumors such as osteosarcom are main restricted due to the inefficacy of current treatments. We propose here the construction of a novel anticancers qualene-based nanomedicine with bone affinity and retention capacity. A squalenyl-hydroxybisphosphonate molecule was synthetized by chemical conjugation of a 1-hydroxyl-1,1-bi-sphosphonatemoiety to the squalenechain. This amphiphilic compound was inserted onto squalenoyl-gemcitabinenano-particles using the nanoprecipitation method. The co-assemblyled to nanoconstructsof 75 nm, with different morphology and colloidal properties. The presence of squalenyl-hydroxybi-sphosphonate enhanced the nanoparticles binding affinity for hydroxyapatite,a mineral present in the bone. Moreover, the in vitro anticancer activity was preserved when tested in commercial and patient-treated derived pedia tricoste osarcomacells. Furtherin vivo studies will shed lighton the potential of these nano medicines for the treatment of bones arcomas.
