Quassinoids
Quassinoids are degraded triterpene lactones (similar to limonoids) of the Simaroubaceae plant family grouped into C-18, C-19, C-20, C-22 and C-25 types. The prototypical member of the group, quassin, was first described in the 19th century from plants of the genus ''Quassia'' from which it gets its name. It was isolated in 1937, and its structure elucidated in 1961. Sources More than 200 currently-known quassinoids have been isolated and identified from various species of simaroubaceae family. Quassinoids can also be extracted from various Simaroubaceae family species such as; '' Ailanthus excelsa'', ''Ailanthus vilmoriniana'', (the fruits of) '' Brucea javanica'', '' Hannoa klaineana'', '' Pierreodendron kerstingii'', '' Quassia africana'', '' Quassia amara'', (the wood of ) '' Picrasma ailanthoides'', '' Picrasma javanica'', '' Picrolemma pseudocoffea'', '' Simaba guianensis'', and '' Simaruba glauca''. They are found in species from American and West African genera (belong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Compound
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances. In this process, bonds between atoms may be broken or new bonds formed or both. There are four major types of compounds, distinguished by how the constituent atoms are bonded together. Molecular compounds are held together by covalent bonds; ionic compounds are held together by ionic bonds; intermetallic compounds are held together by metallic bonds; coordination complexes are held together by coordinate covalent bonds. Non-stoichiometric compounds form a disputed marginal case. A chemical formula specifies the number of atoms of each element in a compound molecule, usin ...

Simaba Guianensis
''Simaba'' is a genus of flowering plants belonging to the family Simaroubaceae. Its native range stretches from southern tropical America and Trinidad, across to western tropical Africa to Angola then across to western Malesia. It was first published by French botanist Jean Baptiste Christophore Fusée Aublet (1720–1778), in Hist. Pl. Guiane on page 409 in 1775. Hans Peter Nooteboom (1934–2022) in 1962 (published in 1963), took a very broad view of the genus ''Quassia'' and included therein various genera including, ''Hannoa'' , '' Odyendyea'' , '' Pierreodendron'' , '' Samadera'' , ''Simaba'' and '' Simarouba'' In 2007, molecular analyses of the Simaroubaceae family (Clayton et al., 2007), suggested the splitting up of genera ''Quassia'' again, with all Nooteboom's synonyms listed above being resurrected as independent genera. Species As accepted by Plants of the World Online; *'' Simaba africana'' *'' Simaba borneensis'' *'' Simaba guianensis'' *'' Simaba monophy ...

In Vitro
''In vitro'' (meaning ''in glass'', or ''in the glass'') Research, studies are performed with Cell (biology), cells or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from ''in vitro'' experiments may not fully or accurately predict the effects on a whole organism. In contrast to ''in vitro'' experiments, ''in vivo'' studies are those conducted in living organisms, including humans, known as clinical trials, and whole plants. Definition ''In vitro'' (Latin language, Latin for "in glass"; often not italicized in English usage) studies are conducted ...

Heterocyclic Compounds With 5 Rings
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles. Examples of heterocyclic compounds include all of the nucleic acids, the majority of drugs, most biomass (cellulose and related materials), and many natural and synthetic dyes. More than half of known compounds are heterocycles. 59% of US FDA-approved drugs contain nitrogen heterocycles. Classification The study of organic heterocyclic chemistry focuses especially on organic unsaturated derivatives, and the preponderance of work and applications involves unstrained organic 5- and 6-membered rings. Included are pyridine, thiophene, pyrrole, and furan. Another large class of organic heterocycles refers to those fused to benzene rings. For example, the fused benzene derivatives of p ...
