Five New Biphenanthrenes from Cremastra appendiculata.
نویسندگان
چکیده
Five new biphenanthrenes, cremaphenanthrenes A-E (1-5), along with six known ones, were isolated from the ethanolic extract of the tubers of Cremastra appendiculata (D. Don) Makino (Orchidaceae). Their structures were elucidated on the basis of extensive spectroscopic analyses. All the compounds obtained were tested in vitro for cytotoxic activities against colon (HCT-116), cervix (Hela), and breast (MDA-MB-231) cancer cell lines. They all showed moderate or weak cytotoxicities to the above cancer cell lines.

Premise of the study: Photosynthetic orchids found in highly shaded forests are often mixotrophic, receiving part of their carbon energy via ectomycorrhizal fungi that had originally received carbohydrate from trees. A photosynthetic orchid, Cremastra appendiculata is also found under highly shaded forest, but our preliminary data suggested that its associated fungi were not ectomycorrhizal. We...
متن کاملImplications of Clonal Structure for Effective Population Size and Genetic Drift in a Rare Terrestrial Orchid, Cremastra appendiculata
Effective population size ( Ne ) influences the degree to which random genetic drift changes allele frequencies, increases inbreeding, and decreases genetic diversity, and thus is a parameter of direct relevance to the conservation of rare species. Few empirical data are available, however, concerning the effects of clonal structure on Ne in plant species reproducing both sexually and asexually...
متن کاملHomoisoflavanone inhibits retinal neovascularization through cell cycle arrest with decrease of cdc2 expression.
Neovascularization in the eye is the most common cause of blindness in all age groups; retinopathy of prematurity (ROP), diabetic retinopathy, and age-related macular degeneration. Despite current advances in surgical treatments, ROP remains as the most serious problem of vision loss in children. Here, we report that homoisoflavanone, a natural product from Cremastra appendiculata, significantl...
متن کاملMolecular Evolution of Chloroplast Genomes of Orchid Species: Insights into Phylogenetic Relationship and Adaptive Evolution
Orchidaceae is the 3rd largest family of angiosperms, an evolved young branch of monocotyledons. This family contains a number of economically-important horticulture and flowering plants. However, the limited availability of genomic information largely hindered the study of molecular evolution and phylogeny of Orchidaceae. In this study, we determined the evolutionary characteristics of whole c...
