High Quality Content by WIKIPEDIA articles! Oenanthotoxin is a toxin extracted from hemlock water dropwort (Oenanthe crocata) and other plants of the genus Oenanthe. It is a central nervous system poison, and acts as a noncompetitive gamma-aminobutyric acid antagonist. This toxin played some role in euthanasia in ancient Sardinia, for inducing risus. It was first isolated by a Boehm scientist in 1876 and was crystallized in 1949 by E.G.C. Clarke, D.E. Kidder and W.D. Robertson (J. Pharm. Pharmacol.). It is structurally closely related to the toxins cicutoxin and carotatoxin.

High Quality Content by WIKIPEDIA articles! Opipramol (Insidon, Pramolan, Ensidon, Oprimol) is an antidepressant and anxiolytic used in Germany and other European countries. Although it is a member of the tricyclic antidepressants, opipramol`s primary mechanism of action is much different in comparison. Most TCAs act as reuptake inhibitors, but opipramol does not, and instead acts as a sigma receptor agonist, among having other properties.
High Quality Content by WIKIPEDIA articles! Organosilicon compounds are organic compounds containing carbon silicon bonds. Organosilicon chemistry is the corresponding science exploring their properties and reactivity. Most organosilicon compounds are similar to the ordinary organic compounds, being colourless, flammable, hydrophobic, and stable. The first organosilicon compound, tetraethylsilane, was discovered by Charles Friedel and James Crafts in 1863 by reaction of tetrachlorosilane with diethylzinc. The carbosilicon silicon carbide is an inorganic compound.
High Quality Content by WIKIPEDIA articles! Organoiron chemistry is the chemistry of organometallic compounds containing a carbon-to-iron chemical bond. Organoiron compounds are relevant in organic synthesis as reagents such as iron pentacarbonyl, diiron nonacarbonyl and disodium tetracarbonylferrate. Iron adopts oxidation states from Fe(-II) through to Fe(IV). Although iron is generally less active in many catalytic applications, it is less expensive and "greener" than other metals. Organoiron compounds feature a wide range of ligands that support the Fe-C bond; as with other organometals, these supporting ligands prominently include phosphines, carbon monoxide, and cyclopentadienyl, but hard ligands such as amines are employed as well.

An organochloride, organochlorine, chlorocarbon, chlorinated hydrocarbon, or chlorinated solvent is an organic compound containing at least one covalently bonded chlorine atom. Their wide structural variety and divergent chemical properties lead to a broad range of applications. Many derivatives are controversial because of the effects of these compounds on the environment and on human and animal health.

They are studied in academic research, but have not received widespread use otherwise. The dominant oxidation states for organogold compounds are I with coordination number 2 and a linear molecular geometry and III with CN = 2 and a planar molecular geometry. The gold carbide Au2C2 was discovered in 1900.
High Quality Content by WIKIPEDIA articles! An organolithium reagent is an organometallic compound with a direct bond between a carbon and a lithium atom. As the electropositive nature of lithium puts most of the charge density of the bond on the carbon atom, effectively creating a carbanion, organolithium compounds are extremely powerful bases and nucleophiles. For use as bases, butyllithiums are often used and are commercially available.
High Quality Content by WIKIPEDIA articles! The origin and usage of the term metalloid is convoluted. Its origin lies in attempts, dating from antiquity, to describe metals and to distinguish between typical and less typical forms. It was first applied to metals that floated on water (lithium, sodium and potassium), and then more popularly to nonmetals. Only recently, since the mid-20th century, has it been widely used to refer to elements with intermediate or borderline properties between metals and nonmetals.
High Quality Content by WIKIPEDIA articles! Orlistat is marketed as a prescription under the trade name Xenical by Roche in most countries, or over-the-counter as Alli by GlaxoSmithKline in the United Kingdom and the United States), also known as tetrahydrolipstatin, is a drug designed to treat obesity. Its primary function is preventing the absorption of fats from the human diet, thereby reducing caloric intake. It is intended for use in conjunction with a physician-supervised reduced-calorie diet. Orlistat is the saturated derivative of lipstatin, a potent natural inhibitor of pancreatic lipases isolated from the bacterium Streptomyces toxytricini. However, due to simplicity and stability, orlistat rather than lipstatin was developed...
