Some drugs developed that include metals interact directly with other metals already present in protein active sites, while other drugs can use metals to interact with amino acids with the highest reduction potential. [4] Figure 2. Structure of Cisplatin, a platinum coordination complex. Examples of metals used in treatment include:
Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .
Polymerization of ethylene oxide is an exothermic process. Overheating or contaminating ethylene oxide with catalysts, such as alkalis or metal oxides, can lead to runaway polymerization, which can end in an explosion after a few hours. Polyethylene oxide, or high-molecular-weight polyethylene glycol, is synthesized by suspension polymerization.
Carboplatin, an example of a metallopharmaceutical. A metallopharmaceutical is a drug that contains a metal as an active ingredient. [1] [2] Most commonly metallopharmaceuticals are used as anticancer or antimicrobial agents. The efficiency of metallopharmaceuticals is crucially dependent on the respective trace metal binding forms. [3]
Applications of iron oxide nanoparticles include terabit magnetic storage devices, catalysis, sensors, superparamagnetic relaxometry, high-sensitivity biomolecular magnetic resonance imaging, magnetic particle imaging, magnetic fluid hyperthermia, separation of biomolecules, and targeted drug and gene delivery for medical diagnosis and ...
In biology and medicine, nitric oxide is however an important signalling molecule in nature and this fact is the basis of the most important applications of metal nitrosyls. The nitroprusside anion, [Fe(CN) 5 NO] 2− , a mixed nitrosyl cyano complex, has pharmaceutical applications as a slow release agent for NO.
Compounds containing metal ions can be used as medicine, such as lithium compounds and auranofin. [19] [20] Metal compounds and ions can also produce harmful effects on the body due to the toxicity of several types of metals. [18] For example, arsenic works as a potent poison due to its effects as an enzyme inhibitor, disrupting ATP production ...
For example, arsenopyrite, a common impurity in gold- and copper-containing ores, liberates arsenic trioxide upon heating in air. The processing of such minerals has led to numerous cases of poisonings, [ 22 ] and after the mine is closed, the leftover trioxide waste will present environmental hazard (as was the case with the Giant Mine , for ...
