Metabolite Identification
Common NameEdaxadiene
DescriptionEdaxadiene is a diterpene metabolite described in biomedical literature. It is produced in vitro from geranylgeranyl diphosphate by the enzymes Rv3377c and Rv3378c in Mycobacterium tuberculosis (Mtb), where it is the most abundant diterpene, exhibiting a specific mass fragmentation pattern (PMID:20670276 ). A related compound, olefin edaxadiene B, is consistently found in the same proportions relative to edaxadiene, suggesting it is a side product of the Rv3378c reaction in vivo (PMID:20670276 ). Additionally, tuberculosinol, a dephosphorylated side-product of the edaxadiene pathway, is the least abundant diterpene in Mtb extracts (PMID:20670276 ). The biosynthetic pathway of edaxadiene and edaxadiene B has been defined through these studies (PMID:20670276 ). Synthesis efforts have led to a structural revision of edaxadiene, with a stereodivergent synthesis of its bicyclic core achieved through a key intramolecular oxidative ketone allylation (PMID:22114734 ). However, discrepancies between spectroscopic data of synthetic constructs and natural isolates have raised questions regarding the structural assignment of edaxadiene (PMID:22114734 ). Further synthesis work has also focused on related compounds, including isotuberculosinol (PMID:20462237 ).
