Cordycepin, or 3'-deoxyadenosine, is a derivative of the nucleoside adenosine, differing from the latter by the replacement of the hydroxy group in the 3' position with a hydrogen. It was initially extracted from the fungus Cordyceps militaris , [ 1 ] but can now be produced synthetically. [ 2 ]
Cordyceps / ˈ k ɔːr d ɪ s ɛ p s / is a genus of ascomycete fungi (sac fungi) that includes over 260 species worldwide, many of which are parasitic. Diverse variants of cordyceps have had more than 1,500 years of use in Chinese medicine. [1]
Like other members of the Cordyceps genus, C. militaris produces the pharmacologically active compound cordycepin. Cordycepin is a nucleoside analogue of adenosine-differing by only a single hydroxyl group. It has been shown to induce apoptosis, reduce inflammation, and inhibit RNA transcription in cell cultures.
Ophiocordyceps sinensis consists of two parts, a fungal endosclerotium (within the caterpillar) and stroma. [12] The stroma is the upper fungal part and is dark brown or black, but can be a yellow color when fresh, and longer than the caterpillar itself, usually 4–10 cm.
Ophiocordyceps unilateralis, commonly known as zombie-ant fungus, [2] is an insect-pathogenic fungus, discovered by the British naturalist Alfred Russel Wallace in 1859. . Zombie ants, infected by the Ophiocordyceps unilateralis fungus, are predominantly found in tropical rainfo
Cordyceps gunni is a species of fungus in the family Cordycipitaceae, and is of the genus Cordyceps.It was originally found and recorded by Gunn in Tasmania and named as Sphaeria gunnii and later moved into the Cordyceps genus and renamed Cordyceps gunnii. [1]
U.S. Census Bureau regions and divisions. Since 1950, the United States Census Bureau defines four statistical regions, with nine divisions. [1] [2] The Census Bureau region definition is "widely used... for data collection and analysis", [3] and is the most commonly used classification system.
The 5-HT 1B receptor as an example of a metabotropic serotonin receptor. Its crystallographic structure in ribbon representation. 5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems.
