Compounds based on CHALCONE. They are important intermediates in the formation of FLAVONOIDS.
A plant genus of the family Apiaceae.
A plant genus of the family SALICACEAE. Members contain salicin, which yields SALICYLIC ACID.
A plant genus of the family FABACEAE. Members contain ISOFLAVONES, some of which show molluscicidal and schistosomicidal activity. Some species of Pongamia have been reclassified to this genus and some to DERRIS.
A group of FLAVONOIDS characterized with a 4-ketone.
The outer layer of the woody parts of plants.
Luciferases from RENILLA that oxidizes certain LUMINESCENT AGENTS to cause emission of PHOTONS.
The location of the atoms, groups or ions relative to one another in a molecule, as well as the number, type and location of covalent bonds.
The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.
Substances that are destructive to protozoans.
A group of phenyl benzopyrans named for having structures like FLAVONES.
Chemicals used in agriculture. These include pesticides, fumigants, fertilizers, plant hormones, steroids, antibiotics, mycotoxins, etc.
Lists of words, usually in alphabetical order, giving information about form, pronunciation, etymology, grammar, and meaning.
The study of the physical and chemical properties of a drug and its dosage form as related to the onset, duration, and intensity of its action.
A plant species of the genus PINUS which is the source of pinosylvin. It is sometimes called Scotch pine or Scots pine, which is also a common name for other species of this genus.
A plant genus in the family PINACEAE, order Pinales, class Pinopsida, division Coniferophyta. They are evergreen trees mainly in temperate climates.
Enzymes from the transferase class that catalyze the transfer of acyl groups from donor to acceptor, forming either esters or amides. (From Enzyme Nomenclature 1992) EC 2.3.
An enzyme that converts UDP glucosamine into chitin and UDP. EC
Gymnosperms are a group of vascular plants whose seeds are not enclosed by a ripened ovary (fruit), in contrast to ANGIOSPERMS whose seeds are surrounded by an ovary wall. The seeds of many gymnosperms (literally, "naked seed") are borne in cones and are not visible. Taxonomists now recognize four distinct divisions of extant gymnospermous plants (CONIFEROPHYTA; CYCADOPHYTA; GINKGOPHYTA; and GNETOPHYTA).
Woody, usually tall, perennial higher plants (Angiosperms, Gymnosperms, and some Pterophyta) having usually a main stem and numerous branches.
Naturally occurring or synthetic substances that inhibit or retard the oxidation of a substance to which it is added. They counteract the harmful and damaging effects of oxidation in animal tissues.
Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).
