Membrane-bound geranylgeranyl diphosphate phosphatases: purification and characterization from Croton stellatopilosus leaves.

Numai utilizatorii înregistrați pot traduce articole

Geranylgeranyl diphosphate phosphatase is an enzyme catalyzing the dephosphorylation of geranylgeranyl diphosphate (GGPP) to form geranylgeraniol (GGOH). The enzyme activity of GGPP phosphatase was detected in leaves of Croton stellatopilosus, a Thai medicinal plant containing plaunotol, a

Molecular cloning and catalytic activity of a membrane-bound prenyl diphosphate phosphatase from Croton stellatopilosus Ohba.

Geranylgeraniol (GGOH), a bioactive acyclic diterpene with apoptotic induction activity, is the immediate precursor of the commercial anti-peptic, plaunotol (18-hydroxy geranylgeraniol), which is found in Croton stellatopilosus (Ohba). From this plant, a cDNA encoding a prenyl diphosphate

Influence of protein phosphatase inhibitors on HL60 cells death induction by dehydrocrotonin.

Numai utilizatorii înregistrați pot traduce articole

Oxidative stress can be involved in several cellular responses, such as differentiation, apoptosis and necrosis. Dehydrocrotonin (DCTN, diterpene lactone) from Croton cajucara, Brazilian medicinal plant, slightly induced NBT-reducing activity. In presence of protein phosphatase inhibitors

Antiulcer activity and subacute toxicity of trans-dehydrocrotonin from Croton cajucara.

Numai utilizatorii înregistrați pot traduce articole

The antiulcerogenic activity of trans-dehydrocrotonin (DHC), a nor-clerodane diterpene isolated from Croton cajucara Benth. (Euphorbiaceae), and its subacute (35 days) toxicity were studied in mice and rats, respectively. For the antiulcerogenic tests, models of gastric ulcers induced in mice by

Six new diterpenoids from Croton laevigatus.

Diterpenes exhibit potent antineoplastic properties against human and murine carcinoma cell lines. trans-Dehydrocrotonin from Croton cajucara, a Brazilian medicinal plant, is a nor-diterpene with antiulcerogenic activity. In this work, we examined the effect of trans-dehydrocrotonin (t-DCTN) on the

Potent anti-angiogenic component in Croton crassifolius and its mechanism of action.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The root of Croton crassifolius Geisel is traditionally used in China for the treatment of snake bites, stomach ache, sternalgia, joint pain, pharyngitis, jaundice and rheumatoid arthritis, while in Thailand, it has been used as an anticancer herbal medicine by the indigenous people. Yet,

Methanol Extract of Croton Pycnanthus Benth. Inhibits Osteoclast Differentiation by Suppressing the MAPK and NF-κB Signaling Pathways.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Osteoclasts are differentiated from monocytes/macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor-kappa B (NF-κB) ligand (RANKL). Croton pycnanthus Benth. (CPB) is a herbal plant that belongs to Euphorbiaceae family. The aim of this study was to

To evaluate the chemopreventive potential of quercetin in an experimental skin carcinogenesis mouse model. Skin tumor was induced by topical application of 7, 12-dimethyl Benz (a) anthracene (DMBA) and Croton oil in Swiss albino mouse. Quercetin was orally administered at a concentration of 200

ent-Kaurane diterpenoids from Croton tonkinensis stimulate osteoblast differentiation.

Numai utilizatorii înregistrați pot traduce articole

Four new ent-kaurane diterpenoids (1-4) were isolated from the leaves of Croton tonkinensis by bioactivity-guided fractionation using an in vitro osteoblast differentiation assay. Their structures were identified as ent-11β-acetoxykaur-16-en-18-ol (1), ent-11α-hydroxy-18-acetoxykaur-16-ene (2),
