FCE 28260 is an orally active 4-azacyclic 5α-reductase (5αR) inhibitor. FCE 28260 exhibits IC₅₀ values for human 5αR type 1 and 5αR type 2 of 36 and 3.3 nM, respectively, and for human and rat prostates with IC₅₀ values of 16 and 15 nM, respectively. FCE 28260 simultaneously blocks the production of dihydrotestosterone (DHT) in the prostate and peripheral tissues. FCE 28260 can significantly inhibit the induction of prostatic and seminal vesicle hyperplasia by testosterone (T) in rat models, without inhibiting the growth of the prostate in DHT implantation models. FCE 28260 can be used for the studies DHT-dependent diseases such as benign prostatic hyperplasia (BPH).
