PRIMARY MedKoo CAT NO: 205818; CAS NO: 1126084-37-4; Description: ASP9521 is a novel, selective, orally bioavailable inhibitor of 17.BETA.-hydroxysteroid dehydrogenase type 5 (17.BETA.HSD5AKR1C3). ASP9521 has demonstrated anti-tumour activity in in vitro and in vivo preclinical models. ASP9521 inhibited conversion of androstenedione (AD) into testosterone (T) by recombinant human or cynomolgus monkey AKR1C3 in a concentration-dependent manner (IC50,human: 11 nmol/L - IC50,monkey: 49 nmol/L). ASP9521 showed >100-fold selectivity for AKR1C3 over the isoform AKR1C2. In LNCaP-AKR1C3 cells, ASP9521 suppressed AD-dependent PSA production and cell proliferation. In patients with mCRPC, ASP9521 demonstrated dose-proportional increase in exposure over the doses evaluated, with an acceptable safety and tolerability profile. However, the novel androgen biosynthesis inhibitor showed no relevant evidence of clinical activity. (Last update: 11/18/2015).
