Cantharidin is a poisonous chemical compound secreted by many species of blister beetle, and most notably by the Spanish fly, Lytta vesicatoria. Image File history File links Cantharidin_structure. ... IUPAC nomenclature is a system of naming chemical compounds and of describing the science of chemistry in general. ... A chemical formula (also called molecular formula) is a concise way of expressing information about the atoms that constitute a particular chemical compound. ...

Cantharidin was first isolated by Pierre Robiquet in 1810. It is an odorless and colorless solid at room temperature. It is secreted by the male blister beetle and given to the female during the mating. Afterwards the female beetle will cover its eggs with it as a defense against predators. The complete mechanism of the biosynthesis is currently unknown. If cantharidin is ingested by human males, as it is excreted by the kidneys it irritates the urinary tract causing spectacular swelling, called priapism, but this is quite painful and does not result in arousal. To meet Wikipedias quality standards, this article may require cleanup. ... Genera See text. ... Biosynthesis is a phenomenon where chemical compounds are produced from simpler reagents. ...

Diluted, it can be used to remove warts and tattoos. In addition, it can be used to treat the small papules of Molluscum contagiosum. However, when ingested by humans, the LD50 dose is around 0.5 mg/kg, with a dose of as little as 10 mg being potentially fatal. This makes the use of canathadarin as an aphrodisiac highly dangerous and it is illegal to sell it for this purpose in many countries. For the Nintendo character, see Wart (Nintendo). ...

Cantharidin : origin and synthesis (935 words)
Among the insects, the cantharidin is produced by the male and transfered to the female during the mating.
The cantharidin inhibits the proteinphospatase 2A (PP2A), an enzyme that operates in the metabolism of glycogen [23].
The first effective synthesis of the cantharidin was made in 1951 by the American chemist G. Stork (born in Belgium) [4] and [5].
