Metabolite Identification

Common Name

Etiocholanolone

Description

Etiocholanolone is the 5-beta-reduced isomer of androsterone. Etiocholanolone is a major metabolite of testosterone and androstenedione in many mammalian species including humans. It is excreted in the urine and is androgenically inactive. Classified a ketosteroid, it causes fever (it is a pyrogen), immunostimulation and leukocytosis. The pyrogenic effect of Etiocholanolone has been shown to be due to the release of interleukin-1 (IL-1) from the leukocytes that are mobilized in response to its production or injection. Etiocholanolone has anticonvulsant activity and may be an endogenous modulator of seizure susceptibility. Significantly increased values of etiocholanolone (along with testoterone and androsterone) an be detected in the urine of men with androgenic alopecia (male pattern baldness).

Enzyme Details

1. Aldo-keto reductase family 1 member C4

General function:: Involved in oxidoreductase activity
Specific function:: Catalyzes the transformation of the potent androgen dihydrotestosterone (DHT) into the less active form, 5-alpha-androstan-3-alpha,17-beta-diol (3-alpha-diol). Also has some 20-alpha-hydroxysteroid dehydrogenase activity. The biotransformation of the pesticide chlordecone (kepone) to its corresponding alcohol leads to increased biliary excretion of the pesticide and concomitant reduction of its neurotoxicity since bile is the major excretory route.
Gene Name:: AKR1C4

2. UDP-glucuronosyltransferase 2B28

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme has glucuronidating capacity with steroid substrates such as 5-beta-androstane 3-alpha,17-beta-diol, estradiol, ADT, eugenol and bile acids. Only isoform 1 seems to be active.

3. UDP-glucuronosyltransferase 2B4

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme is active on polyhydroxylated estrogens (such as estriol, 4-hydroxyestrone and 2-hydroxyestriol) and xenobiotics (such as 4-methylumbelliferone, 1-naphthol, 4-nitrophenol, 2-aminophenol, 4-hydroxybiphenyl and menthol). It is capable of 6 alpha-hydroxyglucuronidation of hyodeoxycholic acid.

6. UDP-glucuronosyltransferase 2B7

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. Its unique specificity for 3,4-catechol estrogens and estriol suggests it may play an important role in regulating the level and activity of these potent and active estrogen metabolites. Is also active with androsterone, hyodeoxycholic acid and tetrachlorocatechol (in vitro).

7. UDP-glucuronosyltransferase 2B15

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme displays activity toward several classes of xenobiotic substrates, including simple phenolic compounds, 7-hydroxylated coumarins, flavonoids, anthraquinones, and certain drugs and their hydroxylated metabolites. It also catalyzes the glucuronidation of endogenous estrogens and androgens.

8. UDP-glucuronosyltransferase 2A1

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: UDP-glucuronosyltransferases catalyze phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase water solubility and enhance excretion. They are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. Active on odorants and seems to be involved in olfaction; it could help clear lipophilic odorant molecules from the sensory epithelium.
