20-alpha-Dihydroprogesterone definition: A biologically active 20-alpha-reduced metabolite of PROGESTERONE. It is converted from progesterone to 20-alpha-hydroxypregn-4-en-3-one by the 20-ALPHA-HYDROXYSTEROID DEHYDROGENASE in the CORPUS LUTEUM and the PLACENTA.
Progesterone Reductase definition: An enzyme that catalyzes the reduction of a 3 beta-hydroxy-delta(5)-steroid to 3-oxo-delta(4)-steroid in the presence of NAD. It converts pregnenolone to progesterone and dehydroepiandrosterone to androstenedione. EC 1.1.1.145.
testosterone 5 alpha reductase definition: catalyzes the reduction of testosterone to 5 alphadihydrotestosterone.
3-Oxo-5-Alpha-Steroid 4-Dehydrogenase 2 definition: 3-oxo-5-alpha-steroid 4-dehydrogenase 2 (254 aa, ~28 kDa) is encoded by the human SRD5A2 gene. This protein plays a role in sexual differentiation and androgen metabolism.
Tetrahydrocannabinol definition: A psychoactive compound extracted from the resin of Cannabis sativa (marihuana, hashish). The isomer delta-9-tetrahydrocannabinol (THC) is considered the most active form, producing characteristic mood and perceptual changes associated with this compound. Dronabinol is a synthetic form of delta-9-THC.
dronabinol definition: A synthetic pill form of delta-9-tetrahydrocannabinol (THC), an active ingredient in marijuana that is used to treat nausea and vomiting associated with cancer chemotherapy.
dronabinol definition: A synthetic form of delta-9-tetrahydrocannabinol, a psychoactive substance found in Cannabis sativa. Dronabinol acts directly on the appetite and vomiting control centers in the brain to stimulate appetite and prevent emesis. Check for "http://www.cancer.gov/Search/ClinicalTrialsLink.aspx?id=39707&idtype=1" active clinical trials or "http://www.cancer.gov/Search/ClinicalTrialsLink.aspx?id=39707&idtype=1&closed=1" closed clinical trials using this agent.

Dronabinol definition: A synthetic form of delta-9-tetrahydrocannabinol, a psychoactive substance found in Cannabis sativa. Dronabinol acts directly on the appetite and vomiting control centers in the brain to stimulate appetite and prevent emesis. (NCI04)
Cholestenone 5 alpha-Reductase definition: An oxidoreductase that catalyzes the conversion of compounds that contain 5-alpha-cholestan-3-one into the cholest-4-en-3-one derivative. It plays an important role in the conversion of TESTOSTERONE into DIHYDROTESTOSTERONE and PROGESTERONE into DIHYDROPROGESTERONE.
Androstenediol definition: An intermediate in TESTOSTERONE biosynthesis, found in the TESTIS or the ADRENAL GLANDS. Androstenediol, derived from DEHYDROEPIANDROSTERONE by the reduction of the 17-keto group (17-HYDROXYSTEROID DEHYDROGENASES), is converted to TESTOSTERONE by the oxidation of the 3-beta hydroxyl group to a 3-keto group (3-HYDROXYSTEROID DEHYDROGENASES).
syn-stemod-13(17)-ene synthase activity definition: Catalysis of the reaction: syn-copalyl diphosphate = stemod-13(17)-ene + diphosphate. [PMID:17141283]
