New Laurene-type Sesquiterpene from Bornean Laurencia nangii.
We report the chemical composition of a population of Bornean Laurencia nangii Masuda. A new compound, neolaurene (1), along with five known metabolites, neolaurallene (2), 2,10-dibromo-3-chloro-α-chamigrene (3), deoxyprepacifenol (4), cycloelatanene B (5) and intricatetraol (6), were isolated and their chemical structures elucidated based on spectroscopic data. In addition, their cytotoxicity ...
متن کاملA new bromoallene-producing chemical type of the red alga Laurencia nangii masuda.
Six populations of Laurencia nangii were found to produce three bromoallenes; dihydroitomanallene B (1), itomanallene B (2) and pannosallene (3). Prior to this report, L. nangii were only known to produce C(15)-acetogenins with acetylene functionality. This could be regarded as a new chemical race of L. nangii. The compound structures were elucidated on the basis of spectroscopic analysis and c...
متن کاملA new cembrane-type diterpenoid from Bornean liverwort Chandonanthus hirtellus.
A new compound, chandonanol (1), along with four known compounds, chandonanthone (2), iso-chandonanthone (3), anastreptene (4), and (6R,7S)-sesquiphellandrene (5), was isolated from the MeOH extract of Bornean liverwort Chandonanthus hirtellus. The structure of the new metabolite was established by analyses of the spectroscopic data (1D NMR, 2D NMR, HRESIMS, and IR). These compounds were tested...
متن کاملBadrakemonin, a New Eremophilane-Type Sesquiterpene from the Roots of Ferula badrakema Kos.-Pol.
Phytochemical investigation of the dichloromethane extract of the dried roots of Ferula badrakema resulted in the identification of one new and six known compounds. Known compounds were sesquiterpene coumarins: mogoltacin, feselol, badrakemin acetate, ferocaulidin, conferone and conferol acetate. The new compound was a sesquiterpene, named badrakemonin. The structures of these compounds were el...
