bitter drimane-type sesquiterpenoids with an isocitricacid group named cryptoporicacids (CA) A-G have been isolated from the fungus Cryptoporous volvatus and their absolute stereostructures established by a combination of chemical transformation, NMR spectral data and X-ray crystallographic analysis. Cryptoporicacids strongly inhibited the release of superoxide anion radicals from guinea-pig peritoneal

The present application relates to a method of producing a drimane sesquiterpene such as albicanol, drimenol and/or derivatives thereof by contacting at least one polypeptide with farnesyl diphosphate (FPP) with a polypeptide comprising a Haloacid dehalogenase (HAD)-like hydrolase domain and having bifunctional terpene synthase activity. The method may be 5 performed in vitro or in vivo. Also provided are amino acid sequences of polypeptides useful in the methods and nucleic acids encoding the polypeptides described. The method further provides host cells or organisms genetically modified to express the polypeptides and useful to produce a drimane sesquiterpene such as albicanol, drimenol and/or derivatives thereof.
