Abstract

The present disclosure relates to novel pharmaceutical compositions comprising a nanoparticle associated with, tether to, or encapsulating a platinum-based active pharmaceutical agent. The platinum-based drug is released from the nanoparticles in a controlled fashion. Also contemplated are methods of making the nanoparticles, as well as methods for using them in the treatment or prevention of diseases or conditions. One embodiment relates to phenanthriplatin nanoparticles and methods of using and making the same.
