The History of Aspirin and Salicin

felix hoffmann aspirin

In 1897, Hoffmann added the acetyl group to various molecules hoping one the one hand to decrease the toxicity and on the other to improving the strength of physiologically active substances while working at Bayer under Arthur Eichengrün. By the time the claim that Hoffmann had initiated the development of aspirin was published, the Nazis had banned Jews from the civil service and from independent positions in the professions and in economic life. He turned again to his bioassay system for the answer and within a few days he had convinced himself and his colleagues that this indeed was the missing mechanism of action. Two years later, a scientist at Strathclyde University in Scotland, Walter Sneader, presented a paper at the of Chemistry's annual conference, in which he claimed that Bayer had been falsely attributing the discovery of aspirin to Hoffmann, when it was actually Hoffmann's lab colleague, Arthur Eichengrün 1867-1949 , who deserved the credit. The controversy over who was primarily responsible for aspirin's development spread through much of the twentieth century and into the twenty-first. In deciding whether it is Hoffmann or Eichengrün who initiated the events leading to the introduction of aspirin, the unreliability of the 1934 footnote about Hoffmann must be balanced against the plausibility of the 1949 paper by Eichengrün.

Aspirin Development

More than a cure for headaches and minor pain, aspirin has been clinically proven to work wonders for many conditions. It quickly became the number-one drug worldwide. Aspirin has been used for pain relief and reducing fevers, and also for heart ailments and recovery from heart surgery. This statement was never disputed by Dreser, who contributed the next article in the same publication. Though Bayer applied for a German patent on the product, this was rejected, as acetylsalicylic acid had been synthesized earlier.

Aspirin Development

Determined to alleviate his father's arthritis, Felix Hoffmann made a pain reliever that was safe for everyday use. But had it only been for a short period, he would not have mentioned it. He was the son of Jakob, an industrialist, and went on to earn a science degree—magna cum laude—from the University of Munich in 1891. Something must have induced him to single out acetylsalicylic acid, and the explanation can be found in a paper written by Eichengrün. Hoffmann was methodically following instructions by Eichengrun to make the drug palatable. Such historical revisionism was not unknown in the Nazi era.

Following the synthesis of aspirin, Hoffmann moved to the pharmaceutical marketing department where he stayed until his retirement in 1928. Sneader asserted that the first mention of Hoffmann as aspirin's discoverer did not appear until a year after this, in 1934. It is likely that Hoffman started by recreating the published methods. A low profile was the order of the day, but that was not enough to prevent his company being forcibly transferred to another owner in 1938. Five years earlier, while in Theresienstadt concentration camp, he had typed a letter now in the Bayer archives with wording similar to his 1949 paper. The Eichengrün version was ignored by historians and chemists until 1999, when Walter Sneader of the Department of Pharmaceutical Sciences at the in re-examined the case and came to the conclusion that indeed Eichengrün's account was convincing and correct and that Eichengrün deserved credit for the invention of aspirin.

Bayer patents aspirin

It was difficult for him to move and painkillers at the time were woefully inadequate or made the patient feel worse via dangerous side-effects. The formula worked and so Hoffmann then convinced Bayer to market the. Hoffman set out to learn his trade by working in pharmacies throughout Germany. In addition to the above benefits of aspirin, it has also been shown to have an antiplatelet effect in blood. He believed, mistakenly, that the drug was harmful to the heart. Salicylic acid is derived from the bark and leaves of the willow tree, and this plant had been known for centuries as having analgesic, or pain-relieving, properties. Hoffman is said to have tested versions of the product on his father to find the safest.

Next to the showcase was a similar one filled with acetylcellulose, today also a product of worldwide importance, whose discovery by me it is impossible to doubt since it was established in a series of German patents from 1901 to 1920. Aspirin has been used for pain relief and reducing fevers, and also for heart ailments and recovery from heart surgery. Before 1915, Aspirin was first sold as a powder. In 1859, chemists created salicylic acid synthetically.

But unfortunately, the substance caused stomach pains that made it difficult for everyday use. However, Felix Hoffmann not only succesfully synthesized acetylsalicylic acid in a stable form usable for medical applications and thus, creating one of the most widely beneficial drugs of all time. Felix Hoffmann first made acetylsalicylic acid, better known today as aspirin, to ease his father's arthritis. Convinced of the potential of acetylsalicylic acid, Eichengrün tested it on himself, experiencing no ill effects. Eichengrun was later interned in a concentration camp, and only in 1949 did he manage to publish his own claim on aspirin, saying that Hoffmann had made aspirin under his direction.

Felix Hoffmann and the Discovery of Aspirin

As of 2015, one survey suggested that as many as one-fourth of heart patients in the United States to prevent cardiovascular disease. His research showed pain medicine in that time was made from willow bark and leaves. In his 1949 paper Eichengrün went on to claim that acetylsalicylic acid was sent to several leading clinics for expert assessment. But when people suffering from pain took the salicylic acid, it caused sever stomach and mouth irritation. He stated that he then surreptitiously gave a supply of it to his colleague Dr Felix Goldmann, who then recruited physicians to evaluate the drug in strict secrecy. In 1971 John Vane began his work on aspirin. People at risk of heart attack are advised to take an aspirin a day, and aspirin is used to prevent and treat stroke.

This claim was later supported by research conducted by historian Walter Sneader. They were first to assign to it the correct structure with the acetyl group connected to the phenolic oxygen. Unlike what Hoffmann had created, these earlier isolations had been unable to produce acetylsalicylic acid in a pure, stable form that could be used on a daily basis. Unlike what Hoffmann had created, these earlier isolations had been unable to produce acetylsalicylic acid in a pure, stable form that could be used on a daily basis. But Felix Hoffmann found a way to make this compound safe for common ingestion. It was depicted in clay tablets made by the ancient Sumerians, whose Mesopotamian settlements in the years between 5000 B.
