Tremetone
Tremetone is a chemical compound found in tremetol, a toxin mixture from snakeroot ('' Ageratina altissima'') that causes milk sickness in humans and trembles in livestock. Tremetone is the main constituent of at least 11 chemically related substances in tremetol. Tremetone is toxic to fish, but not to chicken, and is therefore not the major toxic compound in tremetol. Tremetol can be found in a number of different species of the family Asteraceae, including snakeroot and rayless goldenrod (''Isocoma pluriflora''). Synthesis Tremetol, an oil with a straw-colored tinge, was first isolated from white snakeroot by J.F. Couch in 1929. Column chromatography of tremetol yielded a hydrocarbon, two steroids, and three ketones. Further isolation experiments revealed that tremetone is the major ketone constituent of the compound tremetol. Hence, tremetone was hypothesized to be responsible for the “trembles” that characterize the milk sickness disease. Tremetone was first synthesi ...

Werneria Ciliolata
''Werneria'', also known as the torrent toads or smalltongue toads, is a small genus of "true toads", family Bufonidae. They are found in western Central Africa (Equatorial Guinea, Gabon, and Cameroon), with the greatest species richness in the Western High Plateau of Cameroon. The species generally have restricted or patchy distributions and are considered threatened. Etymology The genus is named after Franz Werner Franz Josef Maria Werner (15 August 1867 in Vienna – 28 February 1939 in Vienna) was an Austrian zoologist and explorer. Specializing as a herpetologist and entomologist, Werner described numerous species and other taxa of frogs, snakes, inse ..., Austrian zoologist and herpetologist who was active in Africa. Description ''Werneria'' are medium-sized toads with a snout-to-vent length between ; females tend to be larger than males. They do not have hearing organs, vocal sacs (they are silent), nor parotoid glands. Skin is smooth. Toe webbing ranges f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Toxins
A toxin is a naturally occurring organic poison produced by metabolic activities of living cells or organisms. Toxins occur especially as a protein or conjugated protein. The term toxin was first used by organic chemist Ludwig Brieger (1849–1919) and is derived from the word toxic. Toxins can be small molecules, peptides, or proteins that are capable of causing disease on contact with or absorption by body tissues interacting with biological macromolecules such as enzymes or cellular receptors. Toxins vary greatly in their toxicity, ranging from usually minor (such as a bee sting) to potentially fatal even at extremely low doses (such as botulinum toxin). Toxins are largely secondary metabolites, which are organic compounds that are not directly involved in an organism's growth, development, or reproduction, instead often aiding it in matters of defense. Terminology Toxins are often distinguished from other chemical agents strictly based on their biological origin. Les ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piceol Ethers
Piceol is a phenolic compound found in the needles and in mycorrhizal roots of Norway spruces (''Picea abies''). Picein is the glucoside of piceol. Uses Piceol is used in the synthesis of several pharmaceutical drugs including octopamine, sotalol, bamethan, and dyclonine. Piceol can be used to make acetaminophen by oxime formation with hydroxylamine and subsequent Beckmann rearrangement in acid. Anticonvulsants are also possible by Mannich reaction: Metabolism Diprenylated derivatives of piceol can be isolated from ''Ophryosporus macrodon''. 4-Hydroxyacetophenone monooxygenase is an enzyme that transforms piceol into O-acetylhydroquinone. This enzyme is found in ''Pseudomonas fluorescens''. See also *Paroxypropione, where the acetyl group is replaced by a propionyl group. *Apocynin Apocynin, also known as acetovanillone, is a natural organic compound structurally related to vanillin. It has been isolated from a variety of plant sources and is being studied for its vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
