产品描述
Degarelix acetate(CAS 号 934016-19-0)是Degarelix(地加瑞克,CAS号214766-78-6,货号:BA2748)的醋酸盐形式,Degarelix是一种强效、高选择性促性腺激素释放激素(GnRH)受体拮抗剂,核心生物活性为竞争性结合 GnRH 受体(G 蛋白偶联受体),阻断 GnRH 介导的信号传导,抑制垂体分泌促黄体生成素(LH)和促卵泡激素(FSH),进而持续降低血清睾酮水平,用于治疗晚期前列腺癌;IC50 具有受体特异性,体外对人 GnRH 受体的竞争结合 IC50 约 0.1-1 nM(体现高亲和力);常用应用浓度:体外细胞实验(垂体细胞、前列腺癌细胞系)采用 0.1-100 nM 梯度浓度(用于受体结合验证、激素分泌抑制实验),动物实验中大鼠皮下注射 0.1-1 mg/kg、恒河猴皮下注射 0.3-1 mg/kg,可在 24-48 小时内显著降低血清 LH、FSH 及睾酮水平;临床有效治疗浓度对应成人晚期前列腺癌治疗方案,负荷剂量为第 1 天皮下注射 240 mg(分两次 120 mg 注射),维持剂量为每 4 周皮下注射 80 mg,稳态下可使睾酮持续降至去势水平(<0.5 ng/mL),无需根据年龄、体重调整剂量(严重肝肾功能不全患者除外),耐受性良好,主要不良反应为注射部位反应、热潮红等。
