17-Ketosteroids
Pharmacologic Substance
Steroids that contain a ketone group at position 17.
Any natural, endogenously-derived, synthetic or semi-synthetic compound with pharmacologic activity. A pharmacologic substance has one or more specific mechanism of action(s) through which it exerts one or more effect(s) on the human or animal body. They can be used to potentially prevent, diagnose, treat or relieve symptoms of a disease. Formulation specific agents and some combination agents are also classified as pharmacologic substances.

estrone
Steroids that contain a ketone group at position 17.
An aromatized C18 steroid with a 3-hydroxyl group and a 17-ketone, a major mammalian estrogen. It is converted from ANDROSTENEDIONE directly, or from TESTOSTERONE via ESTRADIOL. In humans, it is produced primarily by the cyclic ovaries, PLACENTA, and the ADIPOSE TISSUE of men and postmenopausal women.

2-hydroxyestrone
Steroids that contain a ketone group at position 17.
A metabolite formed during the catabolism of estrone by the liver through the hydroxylation of the carbon at position 2 by cytochrome P450 (CYP) enzymes, including CYP1A1 and 1A2, with potential anticarcinogenic activity. The mechanism of action for the antitumor activity of 2-hydroxyestrone is not known but this metabolic product has minimal estrogenic activity compared to the parent compound and other estrone metabolites. Additionally, O-methylation of this compound produces 2-methoxyestradiol (2-MeOE2), which is a potent inhibitor of both cell proliferation and angiogenesis.

formestane
Steroids that contain a ketone group at position 17.
A synthetic steroidal substance with antineoplastic activity. Formestane binds irreversibly to and inhibits the enzyme aromatase, thereby blocking the conversion of cholesterol to pregnenolone and the peripheral aromatization of androgenic precursors into estrogens. (NCI04)

estropipate
Steroids that contain a ketone group at position 17.
A natural estrogenic substance composed of estrone sulfate and piperazine. Estropipate diffuses through the cell membrane and binds to and subsequently activates the nuclear estrogen receptor found in the reproductive tract, breast, pituitary, hypothalamus, liver, and bone. The activated complex binds to the estrogen response element on the DNA and activates the transcription of genes involved in the functioning of the female reproductive system and secondary sex characteristics.

polyestradiol phosphate
Steroids that contain a ketone group at position 17.
A synthetic long-acting polymer derivative of the female sex hormone estradiol. As the primary, most potent estrogen hormone produced by the ovaries, estradiol binds to and activates specific nuclear receptors. Estradiol exhibits mild anabolic and metabolic properties, and increases blood coagulability. Administration of polyestradiol phosphate leads to the marked decrease of testosterone levels and may exhibit a bone mass-preserving effect in patients with prostatic cancer. (NCI04)

trilostane
Steroids that contain a ketone group at position 17.
A synthetic derivative of androstane with adrenocortical suppressive properties. Trilostane reversibly inhibits 3 beta-hydroxysteroid dehydrogenase delta 5-4 isomerase in the adrenal cortex, resulting in the decreased synthesis of mineralocorticoids and glucocorticoids and the decreased conversion of pregnenolone to progesterone.

16 alpha-hydroxyestrone
Steroids that contain a ketone group at position 17.
A metabolite formed during the catabolism of estrone by the liver through the hydroxylation of the carbon at position 16 by cytochrome P450 (CYP) family enzymes, including CYP3A4 and 3A5, with potential carcinogenic activity. With increased estrogenic activity compared to the parent compound, 16alpha-hydroxyestrone (16alpha-OHE1) increases the expression of ER-responsive genes, which leads to increased proliferation of susceptible tumor cells. The ratio between the two estrogen metabolites, 2-hydroxyestrone (2-OHE1), a weak estrogen and metabolite from the 2-hydroxylation pathway, and 16alpha-OHE1, a metabolite from the 16-hydroxylation pathway, may be used to assess the risk of certain cancers; a higher ratio of 2-OHE1:16alpha-OHE1 correlates with decreased cancer risk.

Steroids that contain a ketone group at position 17.
An irreversible steroidal aromatase inhibitor, with antiestrogen and antineoplastic activities. Upon oral administration, exemestane binds irreversibly to and inhibits the enzyme aromatase, thereby blocking the peripheral aromatization of androgens, including androstenedione and testosterone, to estrogens. This lowers estrogen levels in the blood circulation.

2-5A Synthetase
OASL protein, human
An enzyme that catalyzes the conversion of ATP into a series of (2'-5') linked oligoadenylates and pyrophosphate in the presence of double-stranded RNA. These oligonucleotides activate an endoribonuclease (RNase L) which cleaves single-stranded RNA. Interferons can act as inducers of these reactions.
