Linzagolix choline
Based on 1 Customer Validation
Linzagolix choline (KLH-2109 choline) is an orally active GnRH receptor antagonist with Ki values of 27.4 nM and 274.0 nM for the human and rat GnRH receptors, respectively. Linzagolix choline binds to GnRH1R, blocks GnRH signaling, and inhibits the hypothalamic-pituitary-gonadal axis. Linzagolix choline can be used in research on endometriosis, uterine fibroids, benign prostatic hyperplasia, and polycystic ovary syndrome.

体外実験
Linzagolix choline is a potent antagonist of the canine GnRH receptor in transfected 293 cells, with an IC50 of 79.5 nM[4].
Linzagolix choline exhibits potent concentration-dependent antagonism of human and cynomolgus monkey GnRH receptors at multiple concentrations in the HEK293 Ca2+ flux assay, with an IC50 value of 36.7 nM for the human GnRH receptor and an IC50 value of 441.9 nM for the monkey GnRH receptor[5].

体内実験
Linzagolix (25-100 mg/kg; p.o.; single administration) choline inhibits serum estradiol concentrations in female rats after oral administration[3].
Linzagolix (10-100 mg/kg; p.o.; single dose) choline dose-dependently inhibits GnRH agonist-stimulated LH secretion in male rats, and the duration of inhibition is prolonged with increasing dose[4].
Linzagolix (1.25-5 mg/kg; p.o.; single dose) choline produces dose-dependent suppression of serum testosterone in healthy male dogs, with the 5 mg/kg dose maintaining testosterone below the lower limit of quantification within 24 h[4].
Linzagolix (5 mg/kg; p.o.; once daily; 28 days) choline maintains testosterone suppression and significantly reduces prostate weight in dogs with benign prostatic hyperplasia[4].

Animal Model:Sprague-Dawley (female, 10 weeks old at model preparation; Charles River Japan)[3]
-
Dosage:50 mg/kg; 100 mg/kg; 200 mg/kg
-
Administration:p.o.; twice daily; 14 days
-
Result:Cyst volumes were decreased compared with the control group at 50, 100, and 200 mg/kg.
The lowest dose showing decreased cyst volume was 50 mg/kg.
-
Animal Model:Sprague-Dawley (female, 11 weeks old)[3]
-
Dosage:25 mg/kg; 50 mg/kg; 100 mg/kg
-
Administration:p.o.; single administration
-
Result:Serum E2 concentrations were suppressed dose-dependently at 25, 50, and 100 mg/kg compared with vehicle up to 24 h after oral administration.
At 24 h, E2 concentrations in the 25 mg/kg group had recovered to 80% of the vehicle group.
A recovery trend was observed at 50 mg/kg at 24 h.
-
Animal Model:Sprague-Dawley (male)[4]
-
Dosage:10, 30 and 100 mg/kg
-
Administration:p.o.; single dose
-
Result:Inhibited leuprolide-induced LH secretion in a dose-dependent manner; the significant effect persisted up to 12 h after administration in the 10 mg/kg group and up to 16 h after administration in the 30 and 100 mg/kg groups compared with the vehicle control group.
-
Animal Model:Beagle (male; 12 months old)[4]
-
Dosage:1.25, 2.5 and 5 mg/kg
-
Administration:p.o.; single dose
-
Result:Serum testosterone levels showed a circadian rhythm in the vehicle control group, with the lowest levels at approximately noon.
Suppressed serum testosterone concentrations in a dose-dependent manner; serum testosterone levels were below the limit of quantitation up to 12 h after administration of 1.25 and 2.5 mg/kg and up to 24 h after 5 mg/kg.
-
Animal Model:Beagle (male; 44-90 months old at start of administration)[4]
-
Dosage:5 mg/kg
-
Administration:p.o.; once daily; 28 days
-
Result:Serum testosterone levels were constantly reduced throughout the 28-day dosing period (measured on days 1 and 28).
After 4 weeks of repeated administration, prostate weight per body weight was decreased by 41% compared with the control group.
Testis weight showed a downward trend (decreased by 24%) compared with the control group.
-
Animal Model:Sprague-Dawley (female; 10 weeks old at PCOS model preparation)[4]
-
Dosage:200 mg/kg (200×2 mg/kg/day)
-
Administration:p.o.; twice daily; 14 days
-
Result:In Letrozole-exposed control rats, polycystic formation was significantly increased and corpora lutea decreased.
Significantly decreased the number of follicular cysts (9.8 vs control 20.7; normal 1.1) and increased the number of corpora lutea (33.9 vs control 25.3; normal 40.6).
In the insulin tolerance test, the change in blood glucose levels (0-1 h) was 39.8 mg/dL versus 26.4 mg/dL in the control group, indicating significantly reduced insulin resistance.
Serum FSH was significantly decreased (8.96 ng/mL vs control 11.74; normal 6.65), whereas LH (1.40 vs control 2.35; normal 1.03 ng/mL), LH/FSH ratio (0.15 vs control 0.21; normal 0.16) and testosterone (210.99 vs control 146.12; normal 4.00 ng/dL) were not significantly decreased.
