A commonly consumed example of said precursors are androstenedione and androstenediol, both of which are currently banned substances in the United States. [6] [7] However, several illegal steroids, such as 1-testosterone, are still being produced legally under different chemical names, and the majority have not undergone clinical studies. [6] [8]
A steroid with modifications away from testosterone in one or both of these areas is commonly referred to as a "prohormone". These enzymatic changes occur with the body's bidirectional enzymes. [3] [4] On October 22, 2004, President Bush signed into law the Anabolic Steroid Control Act of 2004 (118 Stat. 1661). [5]
The prefix nor-is derived as an abbreviation of the word "normal", used to indicate a demethylated compound. [5] Norepinephrine consists of a catechol moiety (a benzene ring with two adjoining hydroxyl groups in the meta-para position), and an ethylamine side chain consisting of a hydroxyl group bonded in the benzylic position. [6] [7]
The 5α-reduction is a chemical reaction where a functional group attached to the carbon in position 5α of the steroid nucleus is reduced, and a double bond between carbon atoms numbered 4 and 5 (see § Figure 2) in the steroid molecule is replaced to the single bond in a chemical reaction catalyzed by the SRD5A1 enzyme (see examples on the ...
Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone precursor. [4] It is one of the most abundant circulating steroids in humans. [ 5 ] DHEA is produced in the adrenal glands , [ 6 ] the gonads , and the brain. [ 7 ]

11-Deoxycorticosterone (DOC), or simply deoxycorticosterone, also known as 21-hydroxyprogesterone, as well as desoxycortone , deoxycortone, and cortexone, [1] [2] is a steroid hormone produced by the adrenal gland that possesses mineralocorticoid activity and acts as a precursor to aldosterone. [3] It is an active (Na+-retaining ...
Boldione, also known as androstadienedione or 1-dehydroandrostenedione, as well as 1,4-androstadiene-3,17-dione, is an important industrial precursor for various steroid hormones. [1] In the United States the chemical is regulated as a Schedule III Controlled Substance.
