Kaurane-Type Diterpene Glycoside from the Stem Bark ofAcanthopanax trifoliatus
Planta Medica, 2004A new diterpene glycoside, acantrifoside D ( 1), as well as three known diterpenes (2 - 4) were isolated from the stem bark of Acanthopanax trifoliatus from Vietnam. Based on 1D and 2D NMR spectroscopic data, their chemical structures were determined to be 16alpha,17-dihydroxy- ent-kauran-19-oic acid 16- O-beta- D-glucopyranoside 19- O-beta- D ...

A unified synthetic approach to trachylobane-, beyerane-, atisane- and kaurane-type diterpenes
Tetrahedron, 2006A general synthetic approach to the polycyclic carbon skeleton of biogenetically related trachylobane, beyerane, atisane, and kaurane diterpenes from carvone is described. The skeleton of these diterpenes is prepared from a common intermediate, that is, 25, readily prepared from carvone using an IMDA reaction and an intramolecular diazo ketone ...

A New ent-kaurane Diterpene Glycoside from Seeds of Pharbitis nil
Chemistry of Natural Compounds, 2017A new ent-kaurane diterpene glycoside, pharboside H (1), and three known compounds, benzyl β-D-glucopyranoside (2), 1-(4′-O-glucopyranosyl-4′-hydroxy-3′,5′-dimethoxyphenyl)-2{2′′,6′′-dimethoxy-4′′-[1-(E) propen-3-ol]-phenoxy}-propane-l,3-diol (3), and butyl caffeate (4), were isolated from the seeds of Pharbitis nil. The structure of the new compound 1

Kaurane-Related Diterpenes as Leishmania Pteridine Redutase Inhibitors: an In-Silico Study
2013Pteridine reductase-1 (PTR1) is one of enzymes discovered as being responsible for the reduced susceptibility to antifolates (eg, metotrexato) of trypanosomic parasites, which has become a chemotherapeutic target. Therefore, thirteen known kaurane-related diterpenes were evaluated in silico against PTR1 by molecular docking and pharmacophore modeling ...
