Aglaia is a genus of 117 species of woody dioecious trees belonging to the Mahogany family (Meliaceae). These trees occur in the subtropical and tropical forests of Southeast Asia, Northern Australia and the Pacific.
Copper(II) chloride is the chemical compound with the chemical formula CuCl2. The anhydrous form is yellowish brown but slowly absorbs moisture to form a blue-green dihydrate.
The Pauson–Khand reaction is a chemical reaction described as a [2+2+1] cycloaddition between an alkyne, an alkene and carbon monoxide to form a α,β-cyclopentenone. The reaction was discovered by Ihsan Ullah Khand (1935-1980), who was working as a postdoctoral associate with Peter Ludwig Pauson (1925–2013) at the University of Strathclyde in Glasgow. The seminal report dates back to 1970, however a detailed follow up was reported in 1973. Initial findings by Pauson and Khand were intermolecular in nature, however many intramolecular examples have been highlighted in both synthesis and methodology reports, starting a decade later from reaction discovery. This reaction was originally mediated by stoichiometric amounts of dicobalt octacarbonyl, but newer versions are both more efficient and catalytic utilizing different chiral auxiliaries for stereo induction, main group transition-metals, and additives to enhance rate of reactivity and yield. For a more extensive review on PKR, refer to Torres' book.
Chlorogenic acid (CGA) is the ester of caffeic acid and (−)-quinic acid, functioning as an intermediate in lignin biosynthesis. The term "chlorogenic acids" refers to a related polyphenol family of esters, including hydroxycinnamic acids with quinic acid.
Pentacene is a polycyclic aromatic hydrocarbon consisting of five linearly-fused benzene rings. This highly conjugated compound is an organic semiconductor. The compound generates excitons upon absorption of ultra-violet (UV) or visible light; this makes it very sensitive to oxidation. For this reason, this compound, which is a purple powder, slowly degrades upon exposure to air and light.
Betulinic acid is a naturally occurring pentacyclic triterpenoid which has antiretroviral, antimalarial, and anti-inflammatory properties, as well as a more recently discovered potential as an anticancer agent, by inhibition of topoisomerase. It is found in the bark of several species of plants, principally the white birch from which it gets its name, but also the ber tree, selfheal, the tropical carnivorous plants Triphyophyllum peltatum and Ancistrocladus heyneanus, Diospyros leucomelas, a member of the persimmon family, Tetracera boiviniana, the jambul, flowering quince, rosemary, and Pulsatilla chinensis.

Steviol glycosides are the chemical compounds responsible for the sweet taste of the leaves of the South American plant Stevia rebaudiana (Asteraceae) and the main ingredients of many sweeteners marketed under the generic name stevia and several trade names. They also occur in the related species Stevia phlebophylla and in the plant Rubus chingii (Rosaceae).
Piceatannol is a stilbenoid, a type of phenolic compound.
Transient receptor potential cation channel, subfamily V, member 3, also known as TRPV3, is a human gene encoding the protein of the same name.
Taxodone is a naturally occurring diterpenoid found in Taxodium distichum, Rosmarinus officinalis (rosemary), several salvia species and other plants, along with its oxidized rearrangement product, taxodione. Taxodone and taxodione exhibit anticancer, antibacterial, antioxidant, antifungal, insecticide, and antifeedant activities.
Baliospermum montanum, commonly known as red physic nut, wild castor, wild croton and wild sultan seed, is a plant in the family Euphorbiaceae. Baliospermum montanum is a stout undershrub with numerous flowers.
Cucurbitane is a class of chemical compounds with formula C
30H
54. It is a polycyclic hydrocarbon, specifically triterpene. It is also an isomer of lanostane, from which it differs by the formal shift of a methyl group from the 10 to the 9β position in the standard steroid numbering scheme.
A quinone methide is a type of conjugated organic compound that contain a cyclohexadiene with a carbonyl and an exocyclic methylidene or extended alkene unit. It is analogous to a quinone, but having one of the double bonded oxygens replaced with a carbon. The carbonyl and methylidene are usually oriented either ortho or para to each other. There are some examples of transient synthetic meta quinone methides.
Flavaglines are a family of natural products that are found in plants of the genus Aglaia (Meliaceae). These compounds are characterized by a cyclopenta[b]benzofuran skeleton. In 1982 King and colleagues discovered the first member of this family, rocaglamide, based on its antileukemic activity. Since then, about 50 other flavaglines have been characterized. These molecules display strong insecticidal, antifungal, anti-inflammatory, neuroprotective, cardioprotective and anticancer activities. In mouse models of cancer, flavaglines enhance the efficacy of chemotherapies and also alleviate the cardiac adverse effect of these chemotherapies.
δ-Viniferin is a resveratrol dehydrodimer. It is an isomer of epsilon-viniferin. It can be isolated from stressed grapevine leaves. It is also found in plant cell cultures and wine. It can also be found in Rheum maximowiczii.
8-Prenylnaringenin is a prenylflavonoid phytoestrogen. It is reported to be the most estrogenic phytoestrogen known. The compound is equipotent at the two forms of estrogen receptors, ERα and ERβ, and it acts as a full agonist of ERα. Its effects are similar to those of estradiol, but it is considerably less potent in comparison.
The fluorosulfates or fluorosulfonates are a set of salts of fluorosulfuric acid with an ion formula SO3F−. The fluorosulfate anion can be treated as though it were a hydrogen sulfate anion with hydroxyl substituted by fluorine. The fluorosulfate ion has a low propensity to form complexes with metal cations. Since fluorine is similar in size to oxygen, the fluorosulfate ion is roughly tetrahedral and forms salts similar to those of the perchlorate ion. It is isoelectronic with hydrogen sulfate, HSO−
4. When an organic group is substituted for the anions, organic fluorosulfonates are formed.
Mitrephora glabra is a species of plant in the family Annonaceae. It is native to Borneo. Rudolph Scheffer, the Dutch botanist who first formally described the species, named it after its hairless leaves and mature twigs.
Silvestrol is a natural product from the flavagline family, with a cyclopenta[b]benzofuran core structure and an unusual dioxane ether side chain, which is found in the bark of trees from the genus Aglaia, especially Aglaia silvestris and Aglaia foveolata.
