Drugs derived from natural sources are commonly produced either by isolation from their natural source or, as described here, through semisynthesis of an isolated agent. From the perspective of chemical synthesis , living organisms act as highly efficient chemical factories, capable of producing structurally complex compounds through biosynthesis .
The acetylation at position 3 and the conversion into a dihydromorphinone class semisynthetic (at position 14 on the morphine carbon skeleton) allows for the drug to more rapidly enter the central nervous system in greater quantity where it is de-acetylated into hydromorphone, and also converted by other processes into hydromorphinol, morphine ...
Hydrocodone is a semisynthetic opioid, converted from codeine [20] [21] or less often from thebaine. [22] Production using genetically engineered yeasts has been developed but is not used commercially. [23] [24] [25]
Drug detection in body fluids requires specific reference data from the target drug. A common pitfall in the detection of New Psychoactive Substances (NPS) is the lack of reference data available for spectrometers to identify the presence of structurally modified illicit substances.
Artemisinin (/ ˌ ɑːr t ɪ ˈ m iː s ɪ n ɪ n /) and its semisynthetic derivatives are a group of drugs used in the treatment of malaria due to Plasmodium falciparum. [1] It was discovered in 1972 by Tu Youyou, who shared the 2015 Nobel Prize in Physiology or Medicine for her discovery. [2]
Morphine. Synthesis of morphine-like alkaloids in chemistry describes the total synthesis of the natural morphinan class of alkaloids that includes codeine, morphine, oripavine, and thebaine and the closely related semisynthetic analogs methorphan, buprenorphine, hydromorphone, hydrocodone, isocodeine, naltrexone, nalbuphine, oxymorphone, oxycodone, and naloxone.

Most opiates are considered drugs with moderate to high abuse potential and are listed on various "Substance-Control Schedules" under the Uniform Controlled Substances Act of the United States of America. In 2014, between 13 and 20 million people used opioids recreationally (0.3% to 0.4% of the global population between the ages of 15 and 65). [5]
