Titre : Auto-assemblages constitués de peptides pénétrants et de ferrocifène : une plateforme innovante pour le traitement du cancer du poumon

Directeur de Thèse: Pr Catherine PASSIRANI

Co-directrice de thèse : Dr Elise LEPELTIER


The aim of this project was to develop a new type of nanoparticle in order to transport ferrocifen molecules, combining three different strategies: the use of cell-penetrating peptides (CPPs), prodrug and their potential self-association. The synthesis of conjugates (CPP-p54) consisting of two different types of cell-penetrating peptides Argn-p54 (n=6 to 9) and RLW-p54, their self-assembly in water and the complete characterization of the self-assemblies were carried out, by highlighting the importance of the methods used to characterize the suspension.  In vitro studies were also performed on healthy cell line and lung cancer cells showing an improvement in biological activity by a factor 9.

 Key words:

ferrocifen; cell-penetrating peptides; lung cancer
