Morphological and biochemical alterations activated by antitumor clerodane diterpenes

Chemico-Biological Interactions, 2014
Casearia sylvestris Swartz (Salicaceae) is a plant commonly widespread in the Americas. It has oxygenated tricyclic bioactive clerodane diterpenes with antimicrobial, antiulcer, larvicidal, chemopreventive, anti-inflammatory, antioxidant and antiproliferative properties.

A clerodane diterpene and other constituents of Croton megalocarpus

Phytochemistry, 1989
Abstract A novel clerodane-type furano-diterpene with the 9,10-abeo-methyl group has been isolated from Croton megalocarpus as a major constituent. Structure elucidation has been achieved by a combination of spectroscopic measurements including 2D-NMR and NOE experiments, on the parent compound as well as the monoacetyl derivative. Lupeol, betulin,

Rearranged clerodanes and other diterpenes fromMicroglossa pyrrhopappa

Phytochemistry, 1990
Abstract The aerial parts ofMicroglossa pyrrhopappa gave in addition to isochiliolide lactone, nine further rearranged clerodanes, sevencis-clerodanes four alicyclic diterpenes. The structures were elucidated by high field NMR techniques. Biogenetic and chemotaxonomic aspects are discussed briefly.

Abietane and clerodane diterpenes from Salvia regla

Phytochemistry, 1995
The known ursolic and oleanolic acids, the abietane quinone diterpenes, sessein, and deacetylsessein, together with the also known clerodane diterpenes hardwickiic and clerodermic acids were isolated from the aerial parts of Salvia regla. The structure of a novel compound, reglin, present in this species was established by spectral means as ...

Rearranged clerodane diterpenes from Tinospora baenzigeri

Phytochemistry, 1999
Abstract Baenzigeride A, a new rearranged clerodane diterpene and baenzigeride A glucoside, baenzigeroside A, have been isolated from the stems of Tinospora baenzigeri . The structures were established on the basis of the spectroscopic data.

Nor-clerodane diterpenes from Croton cajucara

Phytochemistry, 1989
Abstract A new nor -clerodane diterpene, t -crotonin, was isolated from the cortices of Croton cajucara along with the previously isolated diterpene, of which the structure was not confirmed, dehydrocrotonin. The structures of these compounds were elucidated by chemical and spectroscopic methods.
