The Relationship

: Copper is an essential element for most aerobic organisms, with an important function as a structural and catalytic cofactor, and in consequence, it is implicated in several biological actions. The relevant aspects of chemistry and biochemistry and the importance of copper compounds in medicine give us a comprehensive knowledge of the multifaceted applications of copper in physiology and physiopathology. In this review, we present an outline of the chemistry and the antitumor properties of copper complexes on breast, colon, and lung cancer cells focus on the role of copper in cancer, the relationship between structure-activity, molecular targets, and the study of the mechanism of action involved in its anticancer activity. This overview is expected to contribute to understanding the design, synthesis, uses of copper complexes as antitumor agents in the most common cancers.

Abstract Depolymerisation of a copper(II)/pyrrolidine-based 2D -polymer 2 by 4,4′-bipyridyl [molar ratio: 2 (CuL2) : 1 (Bipy)] and recrystallisation of the reaction product leads to two visually distinguishable crystal charges, composed of dark green octahedra meso-4 and light green rod-shaped crystals racem-5. Separation of the conglomerate of the morphologically different crystals is accomplished by pick out. The structure of the dinuelear complex racem-5 has been established unambigously by X-ray structure analysis. EPR and susceptibility measurements of mixtures of complex meso-4 and racem-5 indicate that there is no interaction be­tween the two copper(II) centres.
