Fulvestrant
An estradiol derivative and estrogen receptor antagonist that is used for the treatment of estrogen receptor-positive, locally advanced or metastatic breast cancer.
Year introduced: 2019 (1991)
Estrogen Receptor Antagonists
Compounds and drugs that bind to and block or inhibit the activation of ESTROGEN RECEPTORS.
Year introduced: 2015
Antineoplastic Agents, Hormonal
Antineoplastic agents that are used to treat hormone-sensitive tumors. Hormone-sensitive tumors may be hormone-dependent, hormone-responsive, or both. A hormone-dependent tumor regresses on removal of the hormonal stimulus, by surgery or pharmacological block. Hormone-responsive tumors may regress when pharmacologic amounts of hormones are administered regardless of whether previous signs of hormone sensitivity were observed. The major hormone-responsive cancers include carcinomas of the breast, prostate, and endometrium; lymphomas; and certain leukemias. (From AMA Drug Evaluations Annual 1994, p2079)
Year introduced: 1996
Estradiol Congeners
Steroidal compounds related to ESTRADIOL, the major mammalian female sex hormone. Estradiol congeners include important estradiol precursors in the biosynthetic pathways, metabolites, derivatives, and synthetic steroids with estrogenic activities.
Year introduced: 2004
Gonadal Hormones
Hormones produced by the GONADS, including both steroid and peptide hormones. The major steroid hormones include ESTRADIOL and PROGESTERONE from the OVARY, and TESTOSTERONE from the TESTIS. The major peptide hormones include ACTIVINS and INHIBINS.
Steroids
A group of polycyclic compounds closely related biochemically to TERPENES. They include cholesterol, numerous hormones, precursors of certain vitamins, bile acids, alcohols (STEROLS), and certain natural drugs and poisons. Steroids have a common nucleus, a fused, reduced 17-carbon atom ring system, cyclopentanoperhydrophenanthrene. Most steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus. (From Hawley's Condensed Chemical Dictionary, 11th ed)
Year introduced: 1963
Gonadal Steroid Hormones
Steroid hormones produced by the GONADS. They stimulate reproductive organs, germ cell maturation, and the secondary sex characteristics in the males and the females. The major sex steroid hormones include ESTRADIOL; PROGESTERONE; and TESTOSTERONE.
Year introduced: 2004 (1963)
Polycyclic Compounds
Compounds which contain two or more rings in their structure.
Year introduced: 2005(1974)
Hormones, Hormone Substitutes, and Hormone Antagonists
A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists.
Year introduced: 1998
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.
Estrenes
Unsaturated derivatives of the ESTRANES with methyl groups at carbon-13, with no carbon at carbon-10, and with no more than one carbon at carbon-17. They must contain one or more double bonds.
Year introduced: 1975
Estranes
A group of compounds forming the nucleus of the estrogenic steroid family.
Year introduced: 1968
Estradiol
The 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position. Estradiol-17-beta is the most potent form of mammalian estrogenic steroids.
Fused-Ring Compounds
Polycyclic compounds with adjacent rings that share the same two adjacent atoms.
Year introduced: 2017
Therapeutic Uses
Uses of chemicals which affect the course of conditions, diseases, syndromes or pathology to benefit the health of an individual.
Physiological Effects of Drugs
Activities which affect organs and systemic functions without regard to a particular disease.
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
Hormone Antagonists
Chemical substances which inhibit the function of the endocrine glands, the biosynthesis of their secreted hormones, or the action of hormones upon their specific sites.
Estrogen Antagonists
Compounds which inhibit or antagonize the action or biosynthesis of estrogenic compounds.
Year introduced: 1978
