General description

The synthetic androgen mibolerone (7α,17α dimethyl-19-nortestosterone) is an androgenic steroid.

Biochem/physiol Actions

Mibolerone is a synthetic anabolic steroid with a similar profile of activity as R1881 (Metribolone) with a higher affinity (Kd = 1.5 nM) for the androgen receptor in human prostate tissue than R1881 (Kd = 2.3 nM).
The synthetic androgen mibolerone (7α,17α dimethyl-19-nortestosterone) reversibly blocks the multiplication of LNCaP (human prostate carcinoma cell line) cells. In prostate, liver, and cultured cells, it serves as an efficient radioactive ligand for the quantitation and characterization of androgen receptors.
