Abstract
Ruthenium complexes hold great potential as alternatives in cancer treatment and have been the most widely studied nonplatinum anticancer drug candidate. During the recent years our group has been involved in the synthesis of new half sandwich ?Ru(η5-C5H5)? derived compounds, of which cytotoxicity was found, in most of the cases, better than that of cisplatin against several cancer cell lines of typically low, medium and high resistance to metallodrugs, namely ovarian, breast, colon and prostate human tumors (A2780, MCF7, MDAMB231, HT29 and PC3 cell lines). The therapeutic effect of one of these compounds was evaluated in an orthotopic triple negative breast cancer (TNBC) mouse model and has demonstrated the in vivo capacity to suppress tumor growth, not presenting the severe side-effects of other non-targeted chemotherapeutic agents. Moreover, autopsy of the animals did not show any metastasis in the lungs or other organs. In this presentation, we present an overview of our most recent progress in this field, highlighting our chief results. Thus, a new generation of compounds will be presented, based in the fragment ?Ru(η5-C5H5)?with appended molecules, in order to optimize our best results already obtained, having also in view the recognition by cancer cells, for target therapy. Finally, studies to understand the pharmacokinetic and the involved mechanisms of action will also be presented.
