Cancer is a heterogeneous and multifactorial disease with high mortality rates worldwide. Medicinal Inorganic Chemistry is a young field that focuses on the design, synthesis, characterization, preclinical evaluation, and mechanism of action of new inorganic compounds known as metallodrugs. Metallodrugs have the advantage of adjusting their physicochemical and stereochemical properties to bind with a wide range of targets, thus preventing the invasion and metastasis of cancer. Several metal compounds show potential in inhibiting signaling pathways associated with cancer progression.
Cancer is a heterogeneous and multifactorial disease that causes high mortality throughout the world; therefore, finding the most effective therapies is a major research challenge. Currently, most anticancer drugs present a limited number of well-established targets, such as cell proliferation or death; however, it is important to consider that the worse progression of cancer toward pathological stages implies invasion and metastasis processes. Medicinal Inorganic Chemistry (MIC) is a young area that deals with the design, synthesis, characterization, preclinical evaluation, and mechanism of action of new inorganic compounds, called metallodrugs. The properties of metallic ions allow enriching of strategies for the design of new drugs, enabling the adjustment of physicochemical and stereochemical properties. Metallodrugs can adopt geometries, such as tetrahedral, octahedral, square planar, and square planar pyramid, which adjusts their arrangement and facilitates binding with a wide variety of targets. The redox properties of some metal ions can be modulated by the presence of the bound ligands to adjust their interaction, thereby opening a range of mechanisms of action. In this regard, the mechanisms of action that trigger the biological activity of metallodrugs have been generally identified by: (a) coordination of the metal to biomolecules (for instance, cisplatin binds to the N7 in DNA guanine, as Pt-N via coordination of the inhibition of enzymes); (b) redox-active; and (c) ROS production. For this reason, a series of metallodrugs can interact with several specific targets in the anti-invasive processes of cancer and can prevent metastasis. The structural base of several metal compounds shows great anticancer potential by inhibiting the signaling pathways related to cancer progression. In this minireview, we present the advances in the field of antimetastatic effects of metallodrugs.
