Relugolix (TAK-385)?is a potent, orally active, nonpeptidic gonadotropin-releasing hormone (GnRH) antagonist. Relugolix possesses high affinity and potent antagonistic activity for human receptor (binding IC50=0.33 nM) and monkey receptor (IC50=0.32 nM) compared with TAK-013 (HY-100209). Relugolix is used for the study of sex-hormone-dependent diseases, such as including endometriosis, uterine fibroids and prostate cancer et al.
Relugolix exhibits strong binding affinity (IC50=0.32 nM) for the monkey receptor comparable to that for the human receptor (IC50=0.33 nM) while displaying a 30000-fold decrease for the rat receptor (IC50=9800 nM). The antagonistic in vitro activity of TAK-385 with respect to the human receptor (IC90=18 nM) exceeded that for the monkey receptor (IC90=1700 nM) by 95-fold in the presence of 40% serum[1].
Relugolix (oral administration
1-3 mg/kg
single dose for pharmacokinetic study) exhibits a good pharmacokinetic profile and obvious suppressive effects of circulating LH levels in monkeys at a dose of 1 mg/kg. The pharmacokinetic profile exhibits with 16.0 ng/mL, 2.7 h, and 90.1 ng for Cmax, Tmax, and AUCo, respectively in male cynomolgus monkeys[1].Relugolix (oral administration
3, 10 or 30 mg/kg
twice daily
4 weeks) significantly decreases the testis weight, and reduces the ventral prostate weight at 3 mg/kg and decreases it to castrate levels at 10 mg/kg in male hGNRHR-knock-in mice[2].Relugolix (oral administration
30, 100 or 200 mg/kg
twice daily
4 weeks) induces constant diestrous phases in all mice within the first week at 100 mg/kg, and significantly decreases the weights of ovaries and uteri at this dose after 4 weeks in female hGNRHR-knock-in mice[2].
