Cytotoxic activities of naturally occurring oleanane-, ursane-, and lupane-type triterpenes on HepG2 and AGS cells
BACKGROUND It is well known that the naturally occurring modified triterpenes in plants have a wide diversity of chemical structures and biological functions. The lupane-, oleanane-, and ursane-type triterpenes are the three major members of natural triterpenes with a wide range of biological properties. A systematic approach is necessary to review their structures and biological activities acc...
متن کاملBioactive oleanane, lupane and ursane triterpene acid derivatives.
Betulinic, ursolic and oleanolic acids isolated from the aerial parts of Eriope blanchetii (Lamiaceae) were subjected to different esterification reactions, yielding 12 C-3 position ester derivatives. All compounds were identified using spectroscopic techniques, such as IR, 1H-NMR and MS. The derivatives were further investigated for their antioxidant level, Artemia salina lethality and antimic...
متن کاملSix new ursane- and oleanane-type triterpenes from the aerial roots of Ficus microcarpa.
Four new ursane-type triterpenes, 3beta-acetoxy-11alpha-methoxy-12-ursene (1), 3beta-acetoxy-11alpha-ethoxy-12-ursene (2), 3beta-acetoxy-11alpha-hydroperoxy-12-ursene (3), 3beta-hydroxy-11alpha-hydroperoxy-12-ursene (4), and two new oleanane-type triterpenes, 3beta-acetoxy-11alpha-ethoxy-12-oleanene (5), 3beta-acetoxy-111alpha-hydroperoxy-12-oleanene (6), together with 3beta-acetoxy-11alpha-hyd...
متن کاملPhenolic Compounds and Pentacyclic Triterpenes
Decoctions, macerations and fumigations of the stem bark and wood of Terminalia brownii 20 Fresen. are used in traditional medicine for fungal infections and as pesticides on field crops and in 21 traditional granaries in Sudan. In addition, T. brownii is commonly used for protecting wooden 22 houses and furniture. Therefore, using agar disc diffusion and macrodilution methods, eight extracts 2...
متن کاملPentacyclic triterpene distribution in various plants - rich sources for a new group of multi-potent plant extracts.
Pentacyclic triterpenes are secondary plant metabolites widespread in fruit peel, leaves and stem bark. In particular the lupane-, oleanane-, and ursane triterpenes display various pharmacological effects while being devoid of prominent toxicity. Therefore, these triterpenes are promising leading compounds for the development of new multi-targeting bioactive agents. Screening of 39 plant materi...
