  • Patent number: 12144896
    Abstract: The treatment of cancer using platinum-based compounds includes certain drawbacks such as biocompatibility, loading efficacy, leakage of drugs during storage and in the bloodstream, more particularly due to the nature of the nanocarriers for platinum delivery. A nanosystem that allows improving platinum-based drug in vivo performance, kinetics and efficacy. In particular, nanoparticles useful as drug delivery system, these nanoparticles being formed from at least: (a) platinum-based drug, (b) poly-L-arginine, and (c) hyaluronic acid. Particularly, these nanoparticles have been tested in terms of entrapment efficiency and also carried out in vitro experiments in 2D cell culture (viability studies on B6KPC3, A549 and HT-29 cells) and 3D cell model (spheroids made of HTC-116) and in vivo experiments (by injecting intravenously to mice the nanoparticles or comparative oxaliplatin solution) to prove their efficiency.
