Name That Steroid: Round Five

As always, your challenge is to correctly identify each steroid from the structural diagrams.

Leave your answers in the comments section. Trivial names are preferred, though nomenclatures or proprietary names will be accepted.

Steroid Biochemistry and Pharmacology. Academic Press; 1970, p127.

For bonus points identify which one is the odd one out; a steroid that as far as I know has no trivial name, has never been used clinically (or recreationally) and appears to have been included in error.

  1. #1 DHT, Dihydrotestosterone; CAS# 521-18-6
    #2 Phenobolin, Nandrolone phenylpropionate; CAS# 62-90-8
    #3 Mestalone, 17-methyl-DHT CAS# 521-11-9
    #4 Norethandrolone, 17α-ethyl-19-nortestosterone; CAS# 52-78-8
    #5 Proviron, Mesterolone; CAS# 1424-00-6
    #6 Orabolin, Ethylestrenol; CAS# 965-90-2
    #7 Superdrol, Methasterone; CAS# 3381-88-2
    #8 Oxandrolone, Anavar, CAS# 53-39-4
    #9 Masteron, Drostanolone propionate, CAS# 521-12-0
    #10 Metenolone, CAS# 969-76-6
    #11 Anadrol, Oxymetholone, CAS# 434-07-1
    #12 Winstrol, Stanazolol, CAS# 302-96-5

    #12 Has a slight drawing error. It is drawn with the double bond off of the #3 position on the A ring connecting to the H as opposed to the C.

    #10 unesterified Metenolone seems to likely have the least amount of use. It was found in one female Olympic athlete

    This would have been a lot easier if I actually had access to the book.

    I think your next identify this steroid should be reader submitted “Steroids that have yet to be on the market, but should be made.” Would likely start an interesting discussion. Such things at 17-methyl analog of THG. Reduced tibolone with a couple extra double bonds.

  2. Good work Justin.
    Yeah there’s a slight mistake on #12 but that wasn’t what I was looking for. Have another look at the stereochemistry of the methyl groups.

  3. Right. They labelled it as “Methalone”, but methalone is actually a trivial name for masteron (drostanolone). See the picture below:
