Anti-angiogenic activity of convallamaroside, the steroidal saponin isolated from the rhizomes and roots of Convallaria majalis L. (1/7)
Angiogenesis plays a pivotal role in tumor growth and represents a key target for chemopreventive intervention. Despite the large number of existing angiogenesis inhibitors, there is still a great demand for new anti-angiogenic compounds. The objective of this study is to investigate the effect of administration of convallamaroside, a steroidal saponin isolated from the lily of the valley (Convallaria majalis L.) to mice on tumor angiogenesis reaction induced by tumor cells. Angiogenic activity was evaluated by mice intradermal test. Convallamaroside showed a significant inhibitory effect on the number of new vessels induced in mice by human kidney tumor cells (p < 0.001). Similarly, administration of convallamaroside to mice decreased the number of new vessels induced by sarcoma mice cells (p < 0.001).

The rhizomes of Convallaria majalis have been analyzed for their steroidal glycoside constituents, resulting in the isolation of a new 5beta-spirostanol triglycoside, named convallasaponin A, along with two known cardenolide glycosides and a known cholestane glycoside. The structure of convallasaponin A was determined on the basis of extensive spectroscopic analysis, including 2D NMR data, and the results of hydrolytic cleavage. The cardenolide glycosides showed tumor specific cytotoxic activity. (+info)Imaging fluorescence detected linear dichroism of plant cell walls in laser scanning confocal microscope. (3/7)

(+info)"Convallaria" is a genus name in botany, which refers to the Lily of the Valley plant. In a medical context, it may be mentioned because all parts of this plant are considered toxic and can cause various symptoms if ingested or come into contact with the skin. These symptoms can include stomach upset, reduced heart rate, and skin irritation. In severe cases, it can lead to more serious complications such as heart rhythm abnormalities and seizures.
It's important to note that while some people use Lily of the Valley extract in traditional medicine or as a natural remedy, it should be used with caution and under the guidance of a healthcare professional due to its potential toxicity.
Oligohymenophorea is a class within the phylum Ciliophora, which includes protozoans commonly known as ciliates. This group is characterized by having a complex ciliary structure called an undulating membrane and a reduced number of oral primordia (hence the name "oligo" meaning few and "hymenophorea" referring to the oral apparatus).
Members of Oligohymenophorea are diverse, ranging from free-living species found in various aquatic environments to parasitic forms that infect animals. Some well-known examples include Tetrahymena, Paramecium, and Ichthyophthirius (the causative agent of "white spot" disease in freshwater fish).
It's important to note that the classification of ciliates has undergone significant revisions in recent years due to advances in molecular biology and ultrastructural studies. As a result, some sources may use different names or classifications for this group.
I'm sorry for any confusion, but "Spirostans" is not a recognized term in medical terminology. It seems like it might be a reference to a specific chemical compound or class of compounds, possibly related to steroids, based on the prefix "spiro-" and the suffix "-stan." However, I cannot provide a precise definition without more context.
If you're referring to a specific medical or scientific concept, could you please provide more information or check the spelling? I'm here to help, and I want to make sure I give you the most accurate and helpful response possible.
Ciliophora is a phylum in the taxonomic classification system that consists of unicellular organisms commonly known as ciliates. These are characterized by the presence of hair-like structures called cilia, which are attached to the cell surface and beat in a coordinated manner to facilitate movement and feeding. Ciliophora includes a diverse group of organisms, many of which are found in aquatic environments. Examples of ciliates include Paramecium, Tetrahymena, and Vorticella.
