产品名称:TAK-700 (ORTERONEL)CAS:426219-18-3别名：6-(6,7-二氢-7-羟基-5H-吡咯并[1,2-C]咪唑-7-基)-N-甲基-2-萘羧酰胺;6-[7-羟基-6,7-二氢-5H-吡咯并[1,2-C]咪唑-7-基]-N-甲基-2-萘甲酰胺英文名：TAK-700
[] - 生物活性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。Phase 3。
- 体外研究In vitro, TAK-700 shows the potent inhibitory activity against rat and human steroid 17,20-lyase inhibitor 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.
- 体内研究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.
