The Controlled Drugs and Substances Act is Canada's federal drug control statute. Passed in 1996 under Prime Minister Jean Chrétien's government, it repeals the Narcotic Control Act and Parts III and IV of the Food and Drugs Act, and establishes eight Schedules of controlled substances and two Classes of precursors. It provides that "The Governor in Council may, by order, amend any of Schedules I to VIII by adding to them or deleting from them any item or portion of an item, where the Governor in Council deems the amendment to be necessary in the public interest."
Phenanthrenoids are chemical compounds formed with a phenanthrene backbone. These compounds occur naturally in plants, although they can also be synthesized.
In enzymology, a 3,4-dihydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione 4,5-dioxygenase (EC 1.13.11.25) is an enzyme that catalyzes the chemical reaction
Dendrobium nobile, commonly known as the noble dendrobium, is a member of the family Orchidaceae. It has become a popular cultivated decorative house plant, because it produces colourful blooms in winter and spring, at a time when little else is in flower. It is also one of the 50 fundamental herbs used in traditional Chinese medicine, known as shí hú or shí hú lán. Dendrobium nobile is one of the most widespread ornamental members of the orchid family. Its blooms are variegated in colour, shading from white through pink and purple, and the many different cultivated varieties produce different sized and coloured blooms.
Ajmalan is a parent hydride used in the IUPAC nomenclature of natural products and also in CAS nomenclature. It is a 20-carbon alkaloid with six rings and seven chiral centres.
Bulbophyllum reptans is a species of orchid in the genus Bulbophyllum.
3,4-DHSA is an organic compound which is the intermediate product of the metabolism of cholesterol, by the bacteria most commonly responsible for tuberculosis. 3,4-DHSA is an acronym for 3,4-dihydroxy-9,10-seco-androst-1,3,5(10)-triene-9,17-dione, the official name of this substance. It is classified as a secosteroid, since one of the four rings of cholesterol from which it is derived is broken.
The flavans are benzopyran derivatives that use the 2-phenyl-3,4-dihydro-2H-chromene skeleton. They may be found in plants. These compounds include the flavan-3-ols, flavan-4-ols and flavan-3,4-diols (leucoanthocyanidin).
A dihydroxyanthraquinone is any of several isomeric organic compounds with formula C
14H
8O
4, formally derived from 9,10-anthraquinone by replacing two hydrogen atoms by hydroxyl groups. Dihyroxyantraquinones have been studied since the early 1900s, and include some compounds of historical and current importance. The isomers differ in the position of the hydroxyl groups, and of the carbonyl oxygens (=O) of the underlying anthraquinone.
A dihydroxynaphthoquinone is any of several organic compounds that can be viewed as derivatives of naphthoquinone through replacement of two hydrogen atoms (H) by hydroxyl groups (OH).
Dihydrostilbenoids (bibenzyls) are natural phenols formed from the dihydrostilbene (bibenzyl) backbone.

This enzyme catalyses the following chemical reaction
2,4-Dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one 2-D-glucosyltransferase is an enzyme with systematic name UDP-alpha-D-glucose:2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one 2-beta-D-glucosyltransferase. This enzyme catalyses the following chemical reaction
4-Hydroxy-7-methoxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl glucoside beta-D-glucosidase (EC 3.2.1.182, DIMBOAGlc hydrolase, DIMBOA glucosidase) is an enzyme with systematic name (2R)-4-hydroxy-7-methoxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D-glucopyranoside beta-D-glucosidase. This enzyme catalyses the following chemical reaction
Gymnopusin is a phenanthrenediol produced by the orchid Bulbophyllum gymnopus. It is also found in Bulbophyllum reptans and Maxillaria densa.
Nudol is a phenanthrenoid of the orchids Eulophia nuda, Eria carinata, Eria stricta and Maxillaria densa.
Orchinol is a 9,10-dihydrophenanthrene, a type of phenanthrenoid. It can be isolated from infected Orchis militaris and infected Loroglossum hircinum with Rhizoctonia repens. This molecule has a phytoalexin effect. It reduces the growth of Cattleya aurantiaca seedlings and has an antifungal activity.
