The use of gold compounds has decreased since the 1980s because of numerous side effects and monitoring requirements, limited efficacy, and very slow onset of action. Most chemical compounds of gold, including some of the drugs discussed below, are not salts, but are examples of metal thiolate complexes.
Most drugs based on gold are Au(I) derivatives. [3] Au(III) (referred to as the auric) is a common oxidation state, and is illustrated by gold(III) chloride, Au 2 Cl 6. The gold atom centers in Au(III) complexes, like other d 8 compounds, are typically square planar, with chemical bonds that have both covalent and ionic character.
Sodium aurothiomalate (INN, known in the United States as gold sodium thiomalate) is a gold compound that is used for its immunosuppressive anti-rheumatic effects. [ 2 ] [ 3 ] Along with an orally-administered gold salt, auranofin , it is one of only two gold compounds currently employed in modern medicine.
It also includes the study of existing drugs, their biological properties, and their quantitative structure-activity relationships (QSAR). [1] [2] Medicinal chemistry is a highly interdisciplinary science combining organic chemistry with biochemistry, computational chemistry, pharmacology, molecular biology, statistics, and physical chemistry.
Lipinski's rule of five, also known as Pfizer's rule of five or simply the rule of five (RO5), is a rule of thumb to evaluate druglikeness or determine if a chemical compound with a certain pharmacological or biological activity has chemical properties and physical properties that would likely make it an orally active drug in humans.
Their new text was first published in 1941 under the title The Pharmacological Basis of Therapeutics: A Textbook of Pharmacology, Toxicology and Therapeutics for Physicians and Medical Student. [1] Because the volume was twice as long as a typical textbook, Macmillan printed few copies, but demand for a readable, up-to-date pharmacological text ...

In 1935, gold drugs were reported to be effective for the treatment of rheumatoid arthritis. [1] Although many patients reacted positively to the drug, gold thioglucose was not uniformly effective. Only one gold drug remains in active clinical use for this purpose in the United States: auranofin although sodium aurothiomalate (gold sodium ...
