Description3-Epikatonic acid, also known as 3-epikatonate, belongs to the class of organic compounds known as pentacyclic triterpenoids. These are terpene molecules containing six isoprene units. In higher plants, the biosynthesis of terpenoids proceeds via two independent pathways localized indifferent cellular compartments. The mevalonate (MVA) pathway in the cytoplasm is responsible for the biosynthesis of sesquiterpenes and triterpenes such as 3-epikatonic acid. In the cytoplasm-localized MVA pathway, three molecules of acetyl-coenzyme A are used to produce MVA. Two ATP react with MVA to produce mevalonate diphosphate, followed by decarboxylation and dehydration with the involvement of a third molecule of ATP to give isopentenyl pyrophosphate(IPP). IPP is isomerized to the other isoprene unit, dimethylallyl pyrophosphate (DMAPP), byisopentenyl-diphosphate-D-isomerase (EC 5.3.3.2). IPP and DMAPP are active hemiterpeneintermediates (C5) in the pathways leading to more complicated terpenoids. DMAPP can produce the fundamental sesquiterpene precursor farnesyl diphosphate (FPP), with the successive addition of two further IPPs. Two molecules of FPP are joined tail-to-tail to yield theprecursor of triterpenes, squalene (C30), from which other triterpenes arise (PMID: 17250858 ).3-Epikatonic acid was first isolated from the plant Cyamopsis tetragonoloba, which is also known as guar or cluster bean (https://Doi.Org/10.1002/Mrc.1009). Cyamopsis tetragonoloba is anannual legume and the source of guar gum. Later it was isolated from Tripterygium wilfordii, Trypterygium hypolaucum and then Austroplenckia populnea. 3-Epikatonic acid has been shown to have antimalarial and anti-trypanosome activity (T. (S.) Cruzi) (PMID: 12048549 ).
