structure
Date introduced: January 1, 1972
Phytoestrogens
Compounds derived from plants, primarily ISOFLAVONES that mimic or modulate endogenous estrogens, usually by binding to ESTROGEN RECEPTORS.
Year introduced: 2005(1978)
Pyrans
Isoflavones
3-Phenylchromones. Isomeric form of FLAVONOIDS in which the benzene group is attached to the 3 position of the benzopyran ring instead of the 2 position.
Year introduced: 1991(1975)
Heterocyclic Compounds, 2-Ring
A class of heterocyclic compounds that include a two-ring fused structure. Both aromatic and non-aromatic ring structures are included in this category.
Year introduced: 1998
Heterocyclic Compounds, 1-Ring
Organic compounds that contain a ring structure made up of carbon and one or more additional elements such as nitrogen and oxygen.
Heterocyclic Compounds
Cyclic compounds that include atoms other than carbon in their ring structure.
Flavonoids
A group of phenyl benzopyrans named for having structures like FLAVONES.
Year introduced: 2004(1963)
Chromones
Benzopyrans
Compounds with a core of fused benzo-pyran rings.
Year introduced: 1966
Heterocyclic Compounds, Fused-Ring
Multiple ring heterocyclic compounds containing two or more rings that share two atoms and one bond in common.
Year introduced: 2017
Physiological Effects of Drugs
Activities which affect organs and systemic functions without regard to a particular disease.
Year introduced: 2004
Pharmacologic Actions
A broad category of chemical actions and uses that result in the prevention, treatment, cure or diagnosis of disease. Included here are drugs and chemicals that act by altering normal body functions, such as the REPRODUCTIVE CONTROL AGENTS and ANESTHETICS. Effects of chemicals on the environment are also included.
Year introduced: 2004(1999)
Chemical Actions and Uses
A group of pharmacologic activities, effects on living systems and the environment, and modes of employment of drugs and chemicals. They are broken into actions, which describe their effects, and uses, which describe how they are employed.
Year introduced: 1999
Hormones, Hormone Substitutes, and Hormone Antagonists
A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists.
Hormones
Chemical substances having a specific regulatory effect on the activity of a certain organ or organs. The term was originally applied to substances secreted by various ENDOCRINE GLANDS and transported in the bloodstream to the target organs. It is sometimes extended to include those substances that are not produced by the endocrine glands but that have similar effects.
Estrogens, Non-Steroidal
Non-steroidal compounds with estrogenic activity.
Year introduced: 1975
Estrogens
Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds.
Year introduced: 1963
