Upon administration, ASP9521 selectively binds to and inhibits the activity of 17bHSD5. This prevents the conversion of the adrenal androgens dehydroepiandrosterone and androstenedione into 5-androstenediol and testosterone. By blocking testosterone production, ASP9521 may inhibit the growth of testosterone-dependent cancers such as castration-resistant prostate cancer (CRPC). 17bHSD5, expressed both in normal prostate tissue and in prostate cancer (PC), plays a crucial role in persistent production of androgens despite castration; its expression is associated with increased malignancy of PC.

개요ASP9521 is an inhibitor of 17β-hydroxysteroid dehydrogenase type 5/aldo-keto reductase 1C3 (17β-HSD5/AKR1C3; IC50 = 120 nM). It is selective for 17β-HSD5/AKR1C3 over AKR1C2 (IC50 = 20 μM). ASP9521 inhibits conversion of androstenedione into testosterone by 17β-HSD5/AKR1C3 (IC50s = 11 and 49 nM for human and cynomolgus monkey enzymes, respectively). It inhibits androstenedione-dependent production of prostate specific androgen (PSA) in and proliferation of LNCaP cells expressing 17β-HSD5/AKR1C3. ASP9521 (3 and 10 mg/kg) inhibits androstenedione-induced intratumor testosterone production in a CWR22R prostate cancer mouse xenograft model.
