TAK-700 (Orteronel) 是一种有效的,高度选择性的,人17,20-lyase抑制剂,IC50为38 nM,比作用于其他CYPs(例如11-羟化酶和CYP3A4)选择性高1000倍以上。TAK-700 (Orteronel) 是一种雄性激素 androgen 生物合成抑制剂。
Information
TAK-700 (Orteronel) is a potent and highly selective human17,20-lyaseinhibitor withIC50of 38 nM, exhibits >1000-fold selectivity over other CYPs (e.g. 11-hydroxylase and CYP3A4). TAK-700 (Orteronel) is anandrogenbiosynthesis inhibitor. Phase 3.
In vitro
In vitro, TAK-700 shows the potent inhibitory activity against rat and human steroid 17,20-lyase with IC50 of 54 nM and 38 nM, respectively. While other CYP isoforms including 11-hydroxylase and CYP3A4 are not significantly affected by TAK-700. In microsomes expressing human CYP isoforms, TAK-700 exhibit greater inhibitory effects on 17,20-lyase with IC50 of 19 nM compared to the other CYP isoforms. TAK-700 shows the inhibitory activity against monkey 17,20-lyase and 17-hydroxylase with IC50 of 27 nM and 38 nM, respectively. In monkey adrenal cells, TAK-700 inhibits the ACTH stimulated production of DHEA and androstenedione with IC50 of 110 nM and 130 nM, respectively. Moreover, TAK-700 also potently inhibits DHEA production in human adrenocortical tumor line H295R cells with IC50 of 37 nM.
In vivo
In cynomolgus monkeys, oral treatment of TAK-700 at a dose of 1 mg/kg markedly reduces serum testosterone and dehydroepiandrosterone (DHEA) levels. Oral treatment of TAK-700 at a dose of 1 mg/kg results in favorable pharmacokinetic parameters with Tmax, Cmax, t1/2 and AUC0-24 hours of 1.7 hours, 0.147 μg/mL, 3.8 hours and 0.727 μg h/mL, respectively.
