Carbene-platinum conjugated : novel anticancer complexes

Abstract : Although platinum-based anticancer drugs are well established, several shortcomings have raised concerns, namely their toxicity and resistance mechanisms. Therefore, improved anticancer drugs are strongly awaited to substitute drugs currently used in clinics. Remarkably, the combination of N-Heterocyclic Carbenes (NHCs) to platinum has recently demonstrated very promising results as anticancer agents. In the aim to access novel drugs, this work emphasizes several structural modifications to improve the cytotoxicity and lower side effects. One strategy developed herein focus on the introduction of pnictogens by ligand exchange to access a synergistic effect. Otherwise, efforts mainly focused on NHC-platinum(IV) complexes from their synthesis to stability investigation and anticancer activities and mechanism of action. Finally, the combination of NHC-Pt drugs to nanodelivery devices has been investigated in order to improve both their biocompatibility and selectivity toward cancer cells.
