phoradendron juniperinum/neoplasms

Four novel proteins (phoratoxins C-F) have been isolated from the North American mistletoe Phoradendron tomentosum. The amino acid sequences of these phoratoxins were determined unambiguously using a combination of Edman degradation and trypsin enzymatic digestion, and by electrospray ionization

OBJECTIVE We previously showed that extracts from Phoradendron serotinum and Croton lechleri exerted in vitro cytotoxic and in vivo antitumor effects and that their main component was rutin (RTN; 3-rhamnosyl-glucosylquercetin). However, it is unknown whether RTN exerts in vivo antitumoral effects on

Mistletoe generally is categorized as American mistletoe or European mistletoe. Despite its well-known potential for toxicity, mistletoe continues to be used as an herbal remedy and recently has received a great deal of media attention. The U.S. Food and Drug Administration classified mistletoe as a

BACKGROUND Phoradendron serotinum is commonly used in Mexican traditional medicine for the empirical treatment of cancer. However, there are no studies regarding the antitumoral or immunomodulatory activities of Phoradendron serotinum. METHODS The in vivo toxicity of ethanolic extracts of

Three new lupane-type triterpenes, 3α,24-dihydroxylup-20(29)-en-28-oic acid (1), 3α,23-dihydroxy-30-oxolup-20(29)-en-28-oic acid (2), and 3α,23-O-isopropylidenyl-3α,23-dihydroxylup-20(29)-en-28-oic acid (3), together with eight known compounds (4-11) were isolated from a methanol extract of

Some of the most effective anti-mitotic microtubule-binding agents, such as paclitaxel (Taxus brevifolia) were originally discovered through robust National Cancer Institute botanical screenings. In this study, a high-through put microarray format was utilized to screen 897 aqueous extracts of

The antimicrobial effects of the Mexican medicinal plants Guazuma ulmifolia, Justicia spicigera, Opuntia joconostle, O. leucotricha, Parkinsonia aculeata, Phoradendron longifolium, P. serotinum, Psittacanthus calyculatus, Tecoma stans and Teucrium cubense were tested against several human multi-drug
