Common NameAvermitilol
DescriptionAvermitilol is a sesquiterpene alcohol belonging to the class of terpenoids. Its biosynthesis involves complex pathways in the bacterium Streptomyces avermitilis, where the enzyme SAV_76 catalyzes the conversion of farnesyl diphosphate (FPP) into avermitilol. Quantum chemical calculations have identified several secondary carbocations as potential intermediates in this biosynthetic pathway (PMID:21322615 ). The structure of avermitilol was elucidated through a combination of NMR techniques, revealing its stereochemistry and confirming its identity as a new sesquiterpene alcohol (PMID:20536237 ). The synthesis proceeds through a cyclization mechanism that involves the formation of an intermediate bicyclogermacrene, which undergoes proton-initiated anti-Markovnikov cyclization and subsequent hydration to yield avermitilol (PMID:20536237 ). The recombinant expression of SAV_76 has also led to the production of avermitilone, a derived ketone, alongside minor amounts of other sesquiterpenes such as germacrene A, germacrene B, and viridiflorol (PMID:20536237 ). This intricate biosynthetic process highlights the chemical complexity and biological significance of avermitilol within the terpenoid family.
