IUPAC Name: (3S,8R,9S,10R,13S,14S)-17-((E)-1-(hydroxyimino)ethyl)-10,13-dimethyl-2,3,4,7,8,9,10,11,12,13,14,15-dodecahydro-1H-cyclopenta[a]phenanthren-3-yl acetate
InChIKey: OVKSHCIVDWZSJD-PYABZAOMSA-N
SMILES: C[C@@]12[C@@]3([C@]([C@]4([C@](C)(CC3)C(C(=NO)C)=CC4)[H])(CC=C1C[C@@H](OC(C)=O)CC2)[H])[H]
Biological Activity: (3β)-3-(Acetyloxy)pregna-5,16-dien-20-one 20-oxime is a human 17α-hydroxylase/C17,20-lyase (P45017α) inhibitor with a human IC50 of 67 nM and a rat IC50 of 2754 nM. (3β)-3-(Acetyloxy)pregna-5,16-dien-20-one 20-oxime blocks the human testicular microsomal enzyme mediating androgen biosynthesis steps. (3β)-3-(Acetyloxy)pregna-5,16-dien-20-one 20-oxime does not inhibit human 5α-reductase in prostatic microsomes[1].
