| Description | [D-Phe2,D-Ala6]-LH-RH is a potent luteinizing hormone-releasing hormone (LH-RH) antagonist, exhibiting significant activity against LH/FSH-RH and possessing the ability to inhibit ovulation [1]. |
| In vivo | [D-Phe2,D-Ala6]-LH-RH effectively suppresses the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) stimulated by LH-RH in immature male rats [1]. Administered subcutaneously at 1 mg/rat, the compound shows significant anti-ovulatory and contraceptive effects [2]. A single subcutaneous dose at varying concentrations (0.625, 1.25, 2.5 mg/kg) leads to a dose-dependent enhancement of LH-RH activity in the stalk-median eminence (SME) while reducing plasma LH-RH activity in 25-day-old hypophysectomized (hypox) rats [3]. A higher dose of 25 mg/kg, administered subcutaneously, effectively prevents ovulation induced by LRH [4]. |
