Antimicrobial Activity of Kaurane Diterpenes against Oral Pathogens

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 2008
Two kaurane diterpenes, ent-kaur-16(17)-en-19-oic acid (KA) and 15-β-isovaleryloxy-entkaur- 16(17)-en-19-oic acid (KA-Ival), isolated from Aspilia foliacea, and the methyl ester derivative of KA (KA-Me) were evaluated against oral pathogens.

Kaurane and trachylobane diterpenes from Xylopia aethiopica

Phytochemistry, 1994
Abstract Phytochemical investigation of Xylopia aethiopica (Annonaceae) has resulted in the isolation of two novel diterpenes, 15-oxo-(-)-trachyloban-19-oic acid and (-)-kaur-15-en-17-al-19-oic acid. Also encountered were the known compounds 15-hydroxy-(-)-trachyloban-19-oic acid, 15β-hydroxy-(-)-kaur-16-en-19-oic acid (as an inseperable mixture), 15-

HPLC quantitation of kaurane diterpenes in Xylopia species

Fitoterapia, 2001
Xylopia frutescens is a tree native to the Brazilian Amazon whose seeds are rich in kaurenoic acid, a diterpene that showed in vitro activity against Trypanosoma cruzi. Aiming to find out alternative sources for kaurenoic acid, the content of some kaurane diterpenes was evaluated in X. aromatica and X.

Correlation of diterpenes of the (–)-kaurane series and atractyligenin

Australian Journal of Chemistry, 1968
19-Nor-16a- and 19-nor-16ß-(-)-kaurane (11) and (111) have been prepared by unambiguous methods from 16a-( -)-kaurane-3a,l7,19-triol (IV) and (-)-kaur-16-ene-3a,l9-diol (V) and have been identified with samples derived from atractyligenin, thus providing conclusive proof for the skeleton of the latter.
