| 包装规格: | 5mg 25mg 100mg 250mg in glass bottle |
| 产品简介: | Relugolix (TAK-385) 是一种有效的,具有口服活性,非肽性促性腺激素释放激素(GnRH) 的拮抗剂。与 TAK-013 (HY-100209 ) 相比,Relugolix 对人 (IC50=0.33 nM) 和猴子 (IC50=0.32 nM) 的受体具有高亲和力和强拮抗活性。Relugolix 用于性激素依赖性疾病的研究,如子宫内膜异位症、子宫肌瘤、前列腺癌等。 |
| 溶解性: | 不溶于水;不溶于乙醇 |
| 体内实验: | 1、请依序添加每种溶剂: 10% DMSO→40% PEG300→5% Tween-80→45% saline Solubility: ≥ 0.83 mg/mL (1.33 mM); Clear solution 此方案可获得 ≥ 0.83 mg/mL (1.33 mM,饱和度未知) 的澄清溶液。 以 1 mL 工作液为例,取 100 μL 8.3 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。 2、请依序添加每种溶剂: 10% DMSO→90% (20% SBE-β-CD in saline) Solubility: ≥ 0.83 mg/mL (1.33 mM); Clear solution 此方案可获得 ≥ 0.83 mg/mL (1.33 mM,饱和度未知) 的澄清溶液。 以 1 mL 工作液为例,取 100 μL 8.3 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中,混合均匀。 3、请依序添加每种溶剂: 10% DMSO→90% corn oil Solubility: ≥ 0.83 mg/mL (1.33 mM); Clear solution 此方案可获得 ≥ 0.83 mg/mL (1.33 mM,饱和度未知) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。 以 1 mL 工作液为例,取 100 μL 8.3 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。 <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;⼀旦配成溶液,请分装保存,避免反复冻融造成的产品失效。 |
| 靶点: | IC50: 0.33 nM (human GnRH) IC50: 0.32 nM (monkey GnRH) |
| 体外研究: | 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. |
| 体内研究: | 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. 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. 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. |
