WebSep 23, 2015 · We have shown that a number of active organometallic anticancer agents based on Ru (II), Os (II), and Ir (III) have potential redox components in their mechanisms of action. For such complexes, the possibility arises of using combination therapy together with redox modulators to increase their potency. WebA number of such complexes have been more extensively studied and indeed found greater clinical acceptance as anticancer agents. Recently, developments in coordination chemistry have allowed the design of complexes with well-defined 3-dimensional structures but in which the metal acts as a structural template rather than a reaction centre.
