This project is based on the synthesis of novel classes of squalene bioconjugates: these compounds contain a squalene tail, that makes them able to self-assemble in water, and a drug unit connected via a easily releasable linker  inside cells. The approach allows the release of active drug through reducible linkages as well as spacer/linker activated through enzymatic hydrolysis. Several potent anticancer drugs are screened  (taxanes, podophillotoxins, epothilones, colchicine, camptotechin derivatives etc).  All the squalenoyl prodrugs can be able to self-assemble and the obtained nanoparticles are fully characterized from a technological point of view. All compounds are evaluated through cell tests and the best candidates are going to be submitted to preclinical evaluation.
