Chanoclavine
Chanoclavine, also known as chanoclavin-l is a tri-cyclic ergot alkaloid (ergoline) isolate of certain fungi. It is mainly produced by members of the genus claviceps Ergot ( ) or ergot fungi refers to a group of fungi of the genus ''Claviceps''. The most prominent member of this group is ''Claviceps purpurea'' ("rye ergot fungus"). This fungus grows on rye and related plants, and produces alkaloids that ca ....

Chanoclavine-I Dehydrogenase
Chanoclavine-I dehydrogenase (, ''easD (gene)'', ''fgaDH (gene)'') is an enzyme with systematic name ''chanoclavine-I:NAD+ oxidoreductase''. This enzyme catalises the following chemical reaction : chanoclavine-I + NAD+ \rightleftharpoons chanoclavine-I aldehyde + NADH + H+ This enzyme catalyses a step in the pathway of ergot alkaloid Ergoline is a chemical compound whose structural skeleton is contained in a variety of alkaloids, referred to as ergoline derivatives or ergoline alkaloids.

Ergoline
Ergoline is a chemical compound whose structural skeleton is contained in a variety of alkaloids, referred to as ergoline derivatives or ergoline alkaloids. Ergoline alkaloids, one being ergine, were initially characterized in ergot. Some of these are implicated in the condition ergotism, which can take a convulsive form or a gangrenous form. Even so, many ergoline alkaloids have been found to be clinically useful. Annual world production of ergot alkaloids has been estimated at 5,000–8,000 kg of all ergopeptines and 10,000–15,000 kg of lysergic acid, used primarily in the manufacture of semi-synthetic derivatives. Others, such as lysergic acid diethylamide, better known as LSD, a semi-synthetic derivative, and ergine, a natural derivative found in ''Argyreia nervosa'', ''Ipomoea tricolor'' and related species, are known psychedelic substances. Natural occurrence Ergoline alkaloids are found in lower fungi and some species of flowering plants: the Mexican species ...

Claviceps
Ergot ( ) or ergot fungi refers to a group of fungi of the genus ''Claviceps''. The most prominent member of this group is ''Claviceps purpurea'' ("rye ergot fungus"). This fungus grows on rye and related plants, and produces alkaloids that can cause ergotism in humans and other mammals who consume grains contaminated with its fruiting structure (called ''ergot sclerotium''). ''Claviceps'' includes about 50 known species, mostly in the tropical regions. Economically significant species include ''C. purpurea'' (parasitic on grasses and cereals), ''C. fusiformis'' (on pearl millet, buffel grass), ''C. paspali'' (on dallis grass), ''C. africana'' (on sorghum), and ''C. lutea'' (on paspalum). ''C. purpurea'' most commonly affects outcrossing species such as rye (its most common host), as well as triticale, wheat, and barley. It affects oats only rarely. ''C. purpurea'' has at least three races or varieties, which differ in their host specificity: *G1 — land grasses of open ...

D2 Receptor
Dopamine receptor D2, also known as D2R, is a protein that, in humans, is encoded by the ''DRD2'' gene. After work from Paul Greengard's lab had suggested that dopamine receptors were the site of action of antipsychotic drugs, several groups, including those of Solomon Snyder and Philip Seeman used a radiolabeled antipsychotic drug to identify what is now known as the dopamine D2 receptor. The dopamine D2 receptor is the main receptor for most antipsychotic drugs. The structure of DRD2 in complex with the atypical antipsychotic risperidone has been determined. Function D2 receptors are coupled to Gi subtype of G protein. This G protein-coupled receptor inhibits adenylyl cyclase activity. In mice, regulation of D2R surface expression by the neuronal calcium sensor-1 (NCS-1) in the dentate gyrus is involved in exploration, synaptic plasticity and memory formation. Studies have shown potential roles for D2R in retrieval of fear memories in the prelimbic cortex and in discrimin ...
