11β-methyl-19-nortestosterone
11β-Methyl-19-nortestosterone
Chemical compound
11β-Methyl-19-nortestosterone (11β-MNT) is a synthetic and orally active anabolic–androgenic steroid (AAS) and a derivative of nandrolone (19-nortestosterone) which was developed by the Contraceptive Development Branch (CDB) of the National Institute of Child Health and Human Development (NICHD) and has not been marketed at this time.[1][2][3]
The C17β dodecylcarbonate ester of 11β-MNT, 11β-methyl-19-nortestosterone 17β-dodecylcarbonate (11β-MNTDC) (CDB-4754), is a prodrug of 11β-MNT.[1][2][3] Along with the closely related AAS dimethandrolone (7α,11β-dimethyl-19-nortestosterone; CDB-1321) and its ester prodrug dimethandrolone undecanoate (CDB-4521), 11β-MNT and 11β-MNTDC are under investigation as potential male contraceptives and to treat male hypogonadism.[1][2][3]
