Julocroton Triqueter
''Croton'' is an extensive flowering plant genus in the spurge family, Euphorbiaceae. The plants of this genus were described and introduced to Europeans by Georg Eberhard Rumphius. The common names for this genus are rushfoil and croton, but the latter also refers to '' Codiaeum variegatum''. The generic name comes from the Greek ('), which means " tick" and refers to the shape of the seeds of certain species. Description ''Croton'' is a diverse and complex taxonomic group of plants ranging from herbs and shrubs to trees. A well-known member of this genus is ''Croton tiglium'', a shrub native to Southeast Asia. It was first mentioned in European literature by Cristóbal Acosta in 1578 as lignum pavanae. The oil, used in herbal medicine as a violent purgative, is extracted from its seeds. Currently, it is considered unsafe and it is no longer listed in the pharmacopeias of many countries. Taxonomy Uses Traditional uses ''C. tiglium'' oil has been used in tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pharmacopeia
A pharmacopoeia, pharmacopeia, or pharmacopoea (from the obsolete typography ''pharmacopœia'', meaning "drug-making"), in its modern technical sense, is a book containing directions for the identification of compound medicines, and published by the authority of a government or a medical or pharmaceutical society. Descriptions of preparations are called monographs. In a broader sense it is a reference work for pharmaceutical drug specifications. Etymology The term derives from grc, φαρμακοποιία ''pharmakopoiia'' "making of (healing) medicine, drug-making", a compound of φάρμακον ''pharmakon'' "healing medicine, drug, poison", the verb ποιεῖν ''poiein'' "to make" and the abstract noun suffix -ία ''-ia''. In early modern editions of Latin texts, the Greek diphthong οι (''oi'') is latinized to its Latin equivalent ''oe'' which is in turn written with the ligature ''œ'', giving the spelling ''pharmacopœia''; in modern UK English, ''œ'' is writ ...

Vermouth
Vermouth (, ) is an aromatized fortified wine, flavoured with various botanicals (roots, barks, flowers, seeds, herbs, and spices) and sometimes colored. The modern versions of the beverage were first produced in the mid- to late 18th century in Turin, Italy. While vermouth was traditionally used for medicinal purposes, it was later served as an apéritif, with fashionable cafés in Turin serving it to guests around the clock. In the late 19th century, it became popular with bartenders as a key ingredient for cocktails, such as the martini, the Manhattan, the Rob Roy, and the Negroni. In addition to being consumed as an apéritif or cocktail ingredient, vermouth is sometimes used as an alternative to white wine in cooking. Historically, there have been two main types of vermouth: sweet and dry. Responding to demand and competition, vermouth manufacturers have created additional styles, including extra-dry white, sweet white (blanc or bianco), red (rosso), amber (ambre), an ...

Campari
Campari () is an Italian alcoholic liqueur, considered an apéritif (20.5%, 21%, 24%, 25%, or 28.5% ABV, depending on the country where it is sold), obtained from the infusion of herbs and fruit (including chinotto and cascarilla) in alcohol and water. It is a type of bitters, characterised by its dark red colour. Use Campari is often used in cocktails and is commonly served with soda water or citrus juice (most often pink grapefruit juice), often garnished with either blood orange or blood lime slice (mainly in Australia) or mixed with prosecco as a spritz. It is produced by the Davide Campari Group, a multinational company based in Italy. Campari is an essential ingredient in the classic Negroni cocktail, the Garibaldi, the Americano (which was named at a time when few Americans were aware of Campari), and the spritz (an aperitif popular in northern Italy). In the Italian market, Campari mixed with soda water is sold in individual bottles as Campari Soda (10% alcohol by vol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sangre De Drago
''Croton lechleri'' is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to northwestern South America. It is commonly known as ''sangre de grado'' (Peruvian Spanish), ''sangre de drago'' (Ecuadorian Spanish) or ''sangre de grada'' (Bolivian Spanish), both of which translate to "dragon's blood".Meza, E.N.(Editor). 1999. They refer to this tree's (and several related species') thick red latex. The latex has medicinal properties, and is used by local peoples as a liquid bandage, applied to seal wounds, as it dries quickly to form a protective skin-like barrier. Its use by native people has led to scientific study and observation of its '' in vitro'' antioxidant activity as well as both mutagenic and antimutagenic behavior. The latex also contains a number of chemicals, including taspine. Oligomeric proanthocyanidins, another kind of chemical contained in the latex, have been investigated for the treatment of HIV-associated diarrhea under th ...

12-O-Tetradecanoylphorbol-13-acetate
12-''O''-Tetradecanoylphorbol-13-acetate (TPA), also commonly known as tetradecanoylphorbol acetate, tetradecanoyl phorbol acetate, and phorbol 12-myristate 13-acetate (PMA) is a diester of phorbol. It is a potent tumor promoter often employed in biomedical research to activate the signal transduction enzyme protein kinase C (PKC). The effects of TPA on PKC result from its similarity to one of the natural activators of classic PKC isoforms, diacylglycerol. TPA is a small molecule drug. In ROS biology, superoxide was identified as the major reactive oxygen species induced by TPA/PMA but not by ionomycin in mouse macrophages. Thus, TPA/PMA has been routinely used as an inducer for endogenous superoxide production. TPA is also being studied as a drug in the treatment of hematologic cancer TPA has a specific use in cancer diagnostics as a B-cell specific mitogen in cytogenetic testing. To view the chromosomes, a cytogenetic test requires dividing cells. TPA is used to stimulate di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ester
In chemistry, an ester is a compound derived from an oxoacid (organic or inorganic) in which at least one hydroxyl group () is replaced by an alkoxy group (), as in the substitution reaction of a carboxylic acid and an alcohol. Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. They perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Phosphoesters form the backbone of DNA molecules. Nitrate esters, such as nitroglycerin, are known for their explosive properties. '' Nomenclature Etymology Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumor Promotion
Tumor promotion is a process in carcinogenesis by which various factors permit the descendants of a single initiated cell to survive and expand in number, i.e. to resist apoptosis and to undergo clonal growth. This is a step toward tumor progression. In order for a tumor cell to survive, it must decrease its expression of tumor suppressor genes such as p53, BRCA1, BRCA2, RB1, or the fas receptor. A tumor suppressor would trigger an apoptotic pathway in a cancer cell if there were DNA damage, polyploidy, or uncontrolled cell growth. Simultaneously, tumor cells need to upregulate oncogenes, which promote or cause downstream activation of growth factors and cell survival signals such as RAS, Mitogen-activated protein kinase kinase, VEGF, or Akt.

Phorbol
Phorbol is a natural, plant-derived organic compound. It is a member of the tigliane family of diterpenes. Phorbol was first isolated in 1934 as the hydrolysis product of croton oil, which is derived from the seeds of the purging croton, '' Croton tiglium''. The structure of phorbol was determined in 1967. Various esters of phorbol have important biological properties, the most notable of which is the capacity to act as tumor promoters through activation of protein kinase C. They mimic diacylglycerols, glycerol derivatives in which two hydroxyl groups have reacted with fatty acids to form esters. The most common and potent phorbol ester is 12-''O''-tetradecanoylphorbol-13-acetate (TPA), also called phorbol-12-myristate-13-acetate (PMA), which is used as a biomedical research tool in contexts such as models of carcinogenesis. History and source Phorbol is a natural product found in many plants, especially those of the Euphorbiaceae and Thymelaeaceae families. Phorbol is the a ...
