MeSH

Decanoic acid ester of nandrolone that is used as an anabolic agent to prevent or treat WASTING SYNDROME associated with severe chronic illness or HIV infection (HIV WASTING SYNDROME). It may also be used in the treatment of POSTMENOPAUSAL OSTEOPOROSIS.

Year introduced: 2019 (1971)

These compounds stimulate anabolism and inhibit catabolism. They stimulate the development of muscle mass, strength, and power.

Year introduced: 2004

Agents that inhibit BONE RESORPTION and/or favor BONE MINERALIZATION and BONE REGENERATION. They are used to heal BONE FRACTURES and to treat METABOLIC BONE DISEASES such as OSTEOPOROSIS.

Year introduced: 2006

Polycyclic compounds with adjacent rings that share the same two adjacent atoms.

Year introduced: 2017

A group of compounds forming the nucleus of the estrogenic steroid family.

Year introduced: 1968

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

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.

A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists.

Year introduced: 1998

C18 steroid with androgenic and anabolic properties. It is generally prepared from alkyl ethers of ESTRADIOL to resemble TESTOSTERONE but less one carbon at the 19 position.

Year introduced: 1965

Compounds which contain two or more rings in their structure.

Year introduced: 2005(1974)

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)

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

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.

Year introduced: 2004

Steroidal compounds related to TESTOSTERONE, the major mammalian male sex hormone. Testosterone congeners include important testosterone precursors in the biosynthetic pathways, metabolites, derivatives, and synthetic steroids with androgenic activities.

Year introduced: 2004

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

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)

Activities which affect organs and systemic functions without regard to a particular disease.
