Terpenoids: Higher
Terpenoids (synonymous with isoprenoids or isopentenoids) are a diverse class of natural products that are derived biosynthetically from an intermediate with a simple five-carbon skeleton (isopentane); higher terpenoids are complex structures that possess minimally between 20 and 40 carbon atoms. Higher terpenoids evolved coincidentally with the evolution of life and play multiple functions in ...
متن کاملNew Naphthoquinone Terpenoids from Marine Actinobacterium, Streptomyces sp. CNQ-509
A member of the marine streptomycete clade MAR4, Streptomyces sp. CNQ-509, has genetic potential for the biosynthesis of hybrid isoprenoids and produces several meroterpenoids such as naphterpin, nitropyrrolin and marinophenazine. Our research on the strain CNQ-509 led to the isolation of two new naphterpin derivatives (1 and 2) comprised of naphthoquinone and geranyl moieties along with the kn...
متن کاملTwo new monoterpene glycosides and trypanocidal terpenoids from Dracocephalum kotschyi.
From the whole plant of Dracocephalum kotschyi BOISS., two new monoterpene glycosides (9, 10), together with seven known terpenoids and a phytosterol (1-8), were isolated. Their structures were determined to be limonen-10-al (1), geranial (2), neral (3), beta-sitosterol (4), oleanolic acid (5), ursolic acid (6), p-mentha-8-en-1,2-diol (7), colosolic acid (8), limonen-10-ol 10-O-beta-D-glucopyra...
متن کاملNew methods for the synthesis of certain alkaloids and terpenoids*
The use of ring-fused gem-dihalocyclopropanes, Au(I)-catalyzed cyclization reactions, and chemoenzymatic techniques in the synthesis of natural products is described.
متن کاملTerpenoids from Achillea setacea.
The aerial parts of Achillea setacea afforded, in addition of a rare monoterpene triol and 12 known sesquiterpene lactones, a new guaianolide containing an endoperoxide ring. Its structure was elucidated by spectral methods.
