Metals and Life Chapter 9. Metals in medicine. Metals and their compounds have been used for medical applications throughout history and it is interesting here to take a brief look at some of the milestones. Some of the earliest examples date from as far back as 3. At present, mass spectrometry MSbased metabolomics has been widely used to obtain new insights into human, plant, and microbial biochemistry drug and biomar. The Study of Organic Chemistry. Organic chemistry is primarily devoted to the unique properties of the carbon atom and its compounds. These compounds play a critical.

There are also reports of gold based medicines being used in China and Arabia around 2. BC. Gold has also been used in dentistry excavated graves in Italy dating from 1. Ft245r Usb Fifo Driver Windows Xp. BC were found to have skulls containing gold bridges. Zinc was also reportedly used to promote the healing of wounds by the Romans. Mercury has been in use in medicine for around 2. I chloride was traditionally used in the 1. Europe, and was also used to treat syphilis, often effectively poisoning the patient. By the 1. 9th century Hg. Cl was incorporated in a tonic known as blue mass and prescribed for many ailments including such diverse conditions as constipation, toothache and depression. The use of mercury compounds is now largely forbidden because of their poisonous properties, but they are still to be found in traditional therapies such as Chinese, Tibetan and Ayurvedic medicines.

The semimetal or metalloid, arsenic, well known as a poison, was also used for medicinal purposes it was prescribed for a range of ailments, such as rheumatism, malaria, tuberculosis and diabetes. The medicinal use of arsenic sulfides was described by the ancient physician Hippocrates however, it was in the 1. Dr Fowlers solution, a mixture of potassium arsenite and lavender water. This was typically taken with wine as a general tonic and aphrodisiac. It was not until the 2. The structure of this drug has only recently been determined Lloyd et al., 2. Figure 9. 1. This drug was later superseded by antibiotics. A lack of vitamin B1. Chapter 7, was found to be the cause of pernicious anaemia. This protein was first isolated in 1. Dorothy Hodgkin using protein X ray crystallography for this and for the structure of penicillin, she was awarded the Nobel Prize in 1.

Its anticancer activity was discovered serendipitously by Barnett Rosenberg in the 1. Intensive research in this area has since spawned the development of other metal complexes for cancer therapy. It was the 2. 0th century that also saw a growth in the use of radioactive metals to treat certain types of cancers, such as bone cancer. Figure 9. 1 Two phenyl arsenic compounds found in the crystal structure of arsphenamine. Activity 9. 1 gives you the opportunity to read an overview of this subject in the opening chapter of Medicinal Applications of Coordination Chemistry, by C. J. Jones and J. R. Thornback, Jones and Thornback, 2. Royal Society of Chemistry e. Books that we will be using throughout this chapter. Read Section 1. 1 of the opening chapter of Medicinal Applications of Coordination Chemistry Jones and Thornback, 2. The complete book can be accessed through the RSC e. Book collection, however this extract is also available as a PDF file by clicking on the following link Extract for Activity 9. Question. Other than as therapeutic agents what other major use do metals find in medicine Reveal Answer. Answer. Metals are also used for diagnostic applications, in particular in imaging. End of answer. As you have seen in this brief introduction the number of metal containing compounds that have found use as therapeutic and diagnostic agents for medical applications is ever expanding, and it will not be possible in a single chapter to discuss the chemistry of all of these in detail. Response Surface Methodology Software here. What we will aim to do here is to highlight examples of some of the different areas in which metal complexes are important and to demonstrate the particular chemical and physical properties that make them useful. The text in this online chapter will be supplemented by video material and also sections of texts from books in the Royal Society of Chemistry e. Book collection which support this topic area. First, we will look at the use of metals as pharmaceuticals in general. We will then consider metal homeostasis, looking in particular at the nature of those diseases which arise when metals are either deficient or present in excess and will see what treatments are available. Next, we will consider the use of metals in imaging. Magnetic resonance imaging MRI is widely used for the diagnosis of many ailments and it has been found that certain gadolinium complexes can be used to enhance the contrast of the image. We will also take a detailed look at the use of radioactive nuclei to monitor the functioning of particular organs in the body. Finally, we shall consider metals as therapeutic agents, in particular those used for the treatment of cancer. This detailed study will consider both the mechanism of operation of cisplatin and other metal anticancer drugs used in chemotherapy, and also the use of radioactive nuclei in radiotherapy. Metals as pharmaceuticals. Before we start to explore some of the different examples of the use of metals for medical applications, we should consider the general factors that arise in the design of metal based pharmaceuticals.

Read Sections 1. 3 and 1. Chapter 1 of Medicinal Applications of Coordination Chemistry Jones and Thornback, 2. The complete book can be accessed through the RSC e. Book collection, however this extract is also available as a PDF file by clicking on the following link Extract for Activity 9. Question. What factors determine the pharmokinetic behaviour of a drug Reveal Answer. Answer. The pharmokinetic behaviour of a drug depends on the rates of absorption, distribution, metabolism and elimination. End of answer. Question. Summarise these processes for the example of a drug injected intravenously into the body, highlighting key issues that might arise at each point. Reveal Answer. Answer. When a drug is injected intravenously into the body, the drug is injected directly into the bloodstream. Here, the solubility of the drug can be an issue, along with competitive complexation with proteins in the bloodstream. In some examples this complexation might be desirable to aid distribution of the drug to where it is required, in others it can be detrimental. The drug will need to be sufficiently stable so that it can have the desired effect before being broken down by metabolic processes and excreted, but not so stable as to remain in the body to become toxic. In many examples, the drug may actually need to be metabolised to produce the active form of the drug. End of answer. Question. What is meant by the term prodrug Reveal Answer. Answer. A prodrug is an example of a drug where the form administered is metabolised in the body to produce the active form. End of answer. In the next two sections we will return to the role of metals in the body and in particular the problems that can arise from too little or too much of a metal and how this can be treated. Metal deficiency. We have seen throughout this book just how vital metals are for many of the key biological processes in organisms. It is therefore not surprising that a deficiency or excess of certain metals can severely compromise an organism, as we addressed briefly in Chapter 1.
