The synthesis of aspirin is classified as an esterification reaction

Discovering mechanisms underlying disparate phenomena is the font of basic science. Science, especially biochemistry and molecular biology, advanced tremendously since aspirin made its debut. The castle of NSAIDs’ working principles was still intact, but siege engines were ready. The first to breach the wall in 1971, and would receive a Nobel Prize for it, was pharmacologist John Vane.

Aspirin works. Willow bark works; it is available as herbal medicine and clinical trials find it effective against osteoarthritic pain. The old NSAIDs work. Chemical analysis brought more knowledge about are working – chemical molecules whose structures are known precisely. However, for seven decades physiological and pharmacological knowledge of the old NSAIDs did not advance much beyond that of willow bark. Both remained on the empirical and phenomenological level. People knew from experience aspirin worked, but lacked scientific knowledge about it worked and it worked like its cousins. aptly called it in 1966: “The wonder drug nobody understands.”

No scientific discovery is solely the work of a single person, as acknowledged in Isaac Newton’s famous aphorism: “If I have seen further, it is by standing on ye shoulders of giants.” So it was with Vane. He was brought to aspirin in 1968 by Henry Collier, a pharmacologist who had worked on it for a decade. Collier had discovered that although both morphine and aspirin kill pain, they act by different principles. Morphine acts on the brain. Aspirin acts locally at the sites of injury. What local biochemical mechanisms underlie aspirin’s actions? Collier’s research was stymied, partly because his tools and techniques were rather blunt.

The second innovation was in marketing. The dyes industry pioneered the practice of targeting not ordinary consumers but professionals. It hired technical salesmen to explain to other technicians how to use various dyes on various fashionable fabrics. Adapting this approach, Bayer mounted an extensive sales campaign for aspirin targeting physicians. It initiated the drug marketing strategy “to help doctors to help their patients,” which thrives alongside advertisements prompting consumers to “ask your doctor about it.”

Exercise 11 Synthesis of Aspirin ..

Many kinds of prostaglandin exist in the body to serve a plethora of physiological functions, some of which are irritable, others beneficial. Prostaglandins are among the chemicals secreted by the body’s immune system when it fights off bacteria and other invaders in injuries. Located around wounds , these chemicals cause pain and inflammation. Following bacterial infection, prostaglandins are also produced the hypothalamus, the brain’s center for controlling body temperature, resulting in a rise in temperature. In their capacities to cause pain, inflammation, and fever, prostaglandins are nuisances. Inhibiting their production, consequently reducing pain, inflammation, and fever, is the main therapeutic value of aspirin.

He also synthesized Aspirin because his father, who had severe arthritis, could not tolerate the salicylic acid he was taking for pain relief.
The Kolbe Synthesis for the production of salicylic acid was created by the German chemist Hermann Kolbe.

How does aspirin curb prostaglandin production? The many kinds of prostaglandin are synthesized by a host of complicated biochemical pathways. However, all pathways share a common stage facilitated by an enzyme called COX, whose action aspirin suppresses.
