PGLU-D-PHE-TRP-SER-TYR-D-ALA-LEU-ARG-PRO-GLY-NH2 Usage And Synthesis
Uses
[D-Phe2,D-Ala6]-LH-RH is a potent LH-RH antagonist. [D-Phe2,D-Ala6]-LH-RH shows anti-LH/FSH-RH and antiovulatory activities[1].
in vivo
[D-Phe2,D-Ala6]-LH-RH inhibits the LH and FSH release induced by LH-RH in immature male rats[1].
[D-Phe2,D-Ala6]-LH-RH (1 mg/rat, SC) shows marked antiovulatory and contraceptive activity[2].
[D-Phe2,D-Ala6]-LH-RH (0.625, 1.25, 2.5 mg/kg; s.c.; single dose; sacrificed 30 minutes) results a dose-dependent increase in stalk-median eminence (SME)-LHRH activity and decreases plasma LHRH activity as well in rats with hypophysectomized (hypox) at 25 days old[3].
[D-Phe2,D-Ala6]-LH-RH (25 mg/kg; s.c.; single dsoe) is effective in blocking the ovulation normally induced by LRH alone[4].
| Animal Model: | Adult female Sprague-Dawley rats (200-250 g)[2] |
| Dosage: | 1 mg/rat |
| Administration: | SC injections, from 12:00 to 14:30 hr on the day of proestrus |
| Result: | Showed marked antiovulatory and contraceptive activity, with 96% inhibition of ovulation. |
