Elagolix sodium is a highly potent, selective, orally-active, short-duration, non-peptide antagonist of the gonadotropin-releasing hormone receptor (GnRHR) (IC50=0.94nM) [1]. Elagolix sodium inhibits the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) by blocking the endogenous GnRH signaling pathway, thereby reducing the production of estradiol and progesterone[2]. Elagolix sodium has been widely used in various studies to alleviate endometriosis and improve uterine fibroids[3].
In vitro, Elagolix sodium treatment at 100μM for 1h inhibited inositol-1-phosphate accumulation induced by GnRH peptide in HEK293T cells[4]. Treatment with 100nM Elagolix sodium for 48 hours significantly reduced the expression level of COL1A1 and inhibited the MAPK pathway in leiomyoma cells [5].
In vivo, Elagolix sodium treatment via oral administration at a dose of 30mg/kg for 4h reduced the LH levels in castrated male cynomolgus macaques[6].

Elagolix sodium是一种高效、选择性、口服活性、短效、非肽类的促性腺激素释放激素受体（GnRHR）拮抗剂（IC50=0.94nM）[1]。Elagolix sodium通过阻断内源性GnRH信号通路，抑制黄体生成素（LH）和卵泡刺激素（FSH）的分泌，从而减少雌二醇和孕酮的产生[2]。Elagolix sodium已被广泛用于各类研究，以缓解子宫内膜异位症并改善子宫肌瘤 [3]。
在体外，使用100µM的Elagolix sodium处理HEK293T细胞1小时，抑制了GnRH肽诱导的肌醇-1-磷酸积累[4]。使用100nM的Elagolix sodium处理48小时，显著降低了平滑肌瘤细胞中COL1A1的表达水平，并抑制了MAPK通路[5]。
在体内，口服给予30mg/kg剂量的Elagolix sodium 4小时，降低了去势雄性食蟹猴的LH水平[6]。
| Cell experiment [1]: | |
Cell lines | HEK293T cells |
Preparation Method | The cDNA of the wild-type GnRH1R was subcloned into the pcDNA3.1(+) expression vector with the HA signal, and expressed in HEK293T cells. HEK293T cells were seeded in six-well plates at a density of 3×105 cells per well, and the culture medium was Dulbecco modified Eagle medium supplemented with 10% fetal bovine serum. The cells were pre-treated with Elagolix sodium (100μM) for 1 hour, and then stimulated with the GnRH peptides for 1 hour. The optical density values (OD) were read at 450nm. |
Reaction Conditions | 100μM; 1h |
Applications | Elagolix sodium treatment inhibited inositol-1-phosphate accumulation induced by GnRH peptide in HEK293T cells. |
| Animal experiment [2]: | |
Animal models | Male cynomolgus macaques |
Preparation Method | A total of six male cynomolgus macaques, aged approximately 3.7-6.5 years, underwent complete testicular resection. Drug administration was carried out at least 4 weeks after the surgery. No sedation was administered to the macaques during the administration, but macaques were temporarily confined outside the cage. A single oral administration of 30mg/kg dose of Elagolix sodium was given, blood samples were collected before and 4 hours after administration to determine the concentration of bioactive LH in the serum samples. |
Dosage form | 30mg/kg for once; p.o. |
Applications | Elagolix sodium treatment reduced the LH levels in castrated male cynomolgus macaques. |
