Biological Activity

Description Orteronel(TAK-700) is a potent and highly selective human 17,20-lyase inhibitor with IC50 of 38 nM, exhibits >1000-fold selectivity over other CYPs (e.g. 11-hydroxylase and CYP3A4). TAK-700 (Orteronel) is an androgen biosynthesis inhibitor. Phase 3.
Targets
17,20-lyase (Human) [1] 17,20-lyase (Rat) [1]
38 nM 54 nM
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. [1] 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. [1] TAK-700 shows the inhibitory activity against monkey 17,20-lyase and 17-hydroxylase with IC50 of 27 nM and 38 nM, respectively. [2] 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. [2]
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. [1] 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.
