TAK-700

SKU: orb1301118

Description

Orteronel (TAK-700) is a highly selective 17,20-lyase inhibitor with an IC50 of 38 nM, showing >1000-fold selectivity over related CYPs. It has been investigated in clinical research, including Phase 3 trials, for conditions like prostate cancer, where it targets androgen biosynthesis in both in vitro and in vivo models.

Bioactivity

• Target IC50:
  17, 20-lyase (human):38 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.

• 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.
