5α-dihydro-11-keto Testosterone (11KDHT) is a full androgen receptor agonist comparable to dihydrotestosterone (DHT) [1][2][3].

Androgen receptor is a nuclear receptor that is activated by the androgenic hormones, testosterone, or dihydrotestosterone in the cytoplasm and then translocating into the nucleus. Androgen receptor acts as a DNA-binding transcription factor that regulates gene expression.

5α-dihydro-11-keto Testosterone is a full AR agonist exhibiting similar activity to DHT at 1 nM [3]. 5α-dihydro-11-keto Testosterone is a metabolite of 11-ketotestosterone and 11β-hydroxyandrostenedione (11OHA4), which is metabolized by 11βHSD, 17βHSD and SRD5A, resulted in significant increase in androgenic activity at a physiologically relevant concentration. 5α-dihydro-11-keto Testosterone represented a novel androgen which may play an important role in driving AR-mediated gene expression [1]. In COS-1 cells, 5α-dihydro-11-keto Testosterone exhibited activity comparable to DHT (96%). 5α-dihydro-11-keto Testosterone might be implicated in driving castration-resistant prostate cancer (CRPC) in the absence of testicular T [3].
