Total synthesis of marine terpenoids
Complex architectures of marine terpenoids and vast assortments of their scaffolds have served as a proving ground for synthetic chemists, inspiring them to develop, assess, and test new methodologies and disconnections. Moreover, besides advancing the field of organic synthesis, marine natural …

DEVELOPING MOLECULAR TOOLS TO IMPROVE TERPENOIDS PRODUCTION IN RHODOSPORIDIUM TORULODIES
Terpenoids produced are usually highly toxic to the host cells, leading to early shut-off of the biosynthesis. Red yeasts, particularly species in Rhodosporidium, were considered high-yielding platform for terpenoids production due to their remarkable potentials for lipid production and their …

Metabolic engineering for the production of functionalized terpenoids in heterologous hosts
Terpenoids are a large and diverse group of secondary metabolites which natively play essential biochemical roles, and have been adopted for a wide range of uses by humans. These molecules are of interest scientifically due to their often complex structures, as well as commercially, with market …

Mono-Oxygenase Activity and Nutritional Ecology of Larvae of the Gypsy Moth, Lymantria Dispar
… high concentrations of potentially toxic terpenoids, we hypothesized that older instar larvae have inducible mono-oxygenases (MFOs) that can detoxify pine terpenoids. To test this hypothesis, NADPH oxidase and O-demethylase specific activities were determined using midgut microsomes from …
