Other metal ions

Other metal ions is a broad classification used to describe inorganic elements that are not typically categorized as primary electrolytes but are essential for biological function or involved in toxicological processes. This group includes trace elements such as iron, copper, zinc, and manganese, which serve as critical cofactors for a wide array of enzymes and structural proteins [1]. These ions are vital for processes ranging from oxygen transport in hemoglobin to the stabilization of DNA-binding proteins [1]. From a therapeutic perspective, these ions are often the focus of chelation therapy to treat poisoning or genetic accumulation disorders, such as Wilson's disease or hemochromatosis [2]. In these cases, drugs like deferoxamine or penicillamine bind the ions to facilitate their excretion from the body [2]. Furthermore, certain metal-based compounds, such as cisplatin or lithium salts, utilize the unique chemical properties of metal ions to exert anticancer or psychotropic effects [3]. Because the term Other metal ions aggregates many distinct chemical entities with vastly different biological roles, it is considered an imprecise and non-canonical designation for a therapeutic target [4]. It is more accurately viewed as a database category for inorganic elements that do not fit into more specific protein-based target classes [4].

Drugs interact with these ions primarily through chelation to facilitate excretion, or the ions themselves act as therapeutic agents by modulating signaling pathways or inducing DNA damage [2, 3].
