Cembrane diterpenoids: Chemistry and pharmacological activities

Phytochemistry, 2023
Cembrane diterpenoids (cembranoids), characterized by a 14-membered carbon ring and wide variety of functional groups, found in marine and terrestrial organisms. Many studies have shown that cembrane diterpenoids have cytotoxic and anti-inflammatory activities and are widely used in the development of new drugs.

A cembrane from Echinodorus grandiflorus

Phytochemistry, 1997
A new cembrane, echinoic acid ((1E,3E,7E,11E)-8-carboxyl-1-isopropyl-5,18-dimethylcyclotetradecatetraene), is a major secondary metabolite from Echinodorus grandiflorus. Its structure was confirmed by spectral and crystallographic analysis.

Cembrane-type diterpenoids from Macaranga pustulata

Fìtoterapìâ, 2018
Three new cembrane-type diterpenoids, deheiculatins M-O (1-3), together with five known analogues (4-8), were isolated from the twigs of Macaranga pustulata King ex Hook. The structures of new compounds 1-3 were elucidated by extensive spectroscopic analyses, modified Mosher's method, and the experimental and calculated electronic circular dichroism ...

Bioactive Cembrane Diterpenoids of Anisomeles indica

Journal of Natural Products, 2008
Five new cembrane-type diterpenoids with a trans-fused alpha-methylene-gamma-lactone (1-5), a new flavonoid glucoside (6), and 17 known compounds were isolated from a methanol extract of Anisomeles indica. The structures of 1-6 were elucidated by spectroscopic analysis, and the absolute configuration of compound 1 was determined using the modified ...

Naturally Occurring Cembranes

1979
The first studies which established the structures of members of the new group of diterpenes known as cembranes appeared in 1962 when Dauben, Thiessen, and Resnick (1), and Kobayashi and Akiyoshi (2) simultaneously published the structure of the hydrocarbon cembrene (1) from pine oleoresins, and Rowland and Roberts (3) published the structure of two ...

New Cembrane Diterpenoids from a Hainan Soft Coral Sinularia sp.

Marine Drugs, 2012
Five new cembrane diterpenoids, named sinuflexibilins A–E (1–5), along with nine other known diterpenoids (6–14), have been isolated from the organic extract of a Hainan soft coral Sinularia sp. Their structures were determined on the basis of extensive spectroscopic analyses and by comparison of their spectral data with those of related metabolites ...
