Methandriol (brand names Anabol, Crestabolic, Cytobolin, Diandren, Durabolic, Madiol, Mestenediol, Methabolic, Methydiol, Sterabolic, Stenediol), also known as methylandrostenediol, is an androgen and anabolic steroid (AAS) medication which was developed by Organon and is used in both oral and injectable (as methandriol dipropionate, methandriol propionate, or methandriol bisenanthoyl acetate) formulations. It is an orally active 17ñ-alkylated AAS and a derivative of the endogenous androgen prohormone androstenediol.
Methandriol has been used in the treatment of breast cancer in women. It has been reported to be almost as virilizing as comparable doses of testosterone propionate and methyltestosterone in women.
Methandriol (brand name Androteston M, Notandron, Protandren) was previously marketed as 25 mL and 50 mg/mL aqueous suspensions for use by intramuscular injection.
Methandriol, also known as 17ñ-methyl-5-androstenediol or as 17ñ-methylandrost-5-ene-3ò,17ò-diol, is a synthetic androstane steroid and a 17ñ-alkylated derivative of 5-androstenediol (androst-5-ene-3ò,17ò-diol). A number of esters of methandriol exist, including methandriol dipropionate (methylandrostenediol 3ò,17ò-dipropionate), methandriol propionate (methylandrostenediol 3ò-propionate), methandriol bisenanthoyl acetate (methylandrostenediol 3ò,17ò-dioxononanoate), and methandriol diacetate (methylandrostenediol 3ò,17ò-diacetate; never marketed). Methandriol is closely related to methyltestosterone (17ñ-methyltestosterone or 17ñ-methylandrost-4-ene-17ò-ol-3-one).
An analogue of methandriol is its positional isomer methyl-4-androstenediol (17ñ-methylandrost-4-ene-3ò,17ò-diol). Another analogue of methandriol is ethynylandrostanediol (17ñ-ethynyl-5ñ-androstane-3ò,17ò-diol) as well as its ester ethandrostate (ethynylandrostanediol 3ò-cyclohexylpropionate).
Methandriol was first synthesized in 1935 along with methyltestosterone and mestanolone.
Methandriol is the generic name of methylandrostenediol and its .
Methandriol remains marketed for clinical use only in Taiwan and for veterinary use (as methandriol dipropionate) only in Australia.
