产品描述
曲普瑞林(CL118532;AY25650;Wy42462;达必肽;曲普瑞林)是一种促性腺激素释放激素激动剂(GnRH激动剂),获准用于治疗癌症。它通过持续刺激垂体,降低垂体分泌促性腺激素黄体生成素(LH)和卵泡刺激素(FSH)。与其他GnRH激动剂一样,曲普瑞林可用于治疗激素敏感性癌症,例如前列腺癌或乳腺癌、性早熟、雌激素依赖性疾病(例如子宫内膜异位症或子宫肌瘤),以及辅助生殖。它也用于治疗性别焦虑症。
曲普瑞林(CAS号:57773-63-4)是一种合成的促性腺激素释放激素(GnRH)十肽激动剂类似物,分子式为C₆₄H₈₂N₁₈O₁₃,分子量为1311.47 g/mol。该化合物在第6位引入了D-色氨酸取代,与天然GnRH相比,这增强了其受体结合亲和力并延长了其血浆半衰期。曲普瑞林比天然GnRH效力更强,且具有更高的抗蛋白水解能力,它通过与垂体前叶上的GnRH受体高亲和力结合而发挥GnRH激动剂的作用。曲普瑞林已获得美国食品药品监督管理局 (FDA) 批准,用于治疗 2 岁及以上儿童患者的晚期前列腺癌、子宫内膜异位症和中枢性性早熟。
曲普瑞林是一种合成的十肽类激动剂,是促黄体生成素释放激素 (LHRH)(也称为促性腺激素释放激素 (GnRH))的类似物。它是一种强效的 GnRH 超激动剂,长期给药后可逆性抑制促性腺激素的分泌。曲普瑞林用于晚期前列腺癌、子宫内膜异位症、中枢性性早熟的姑息治疗,以及辅助生殖技术。它也以 Decapeptyl、Trelstar 和 Triptodur 等商品名而闻名。
生物活性&实验参考方法
靶点
Gonadotropin-releasing hormone agonist (GnRH)
Triptorelin binds with high affinity to the gonadotropin-releasing hormone receptor (GnRHR) on anterior pituitary cells, which are Gq/11 protein-coupled seven-transmembrane receptors . By activating the GnRH receptor, triptorelin stimulates the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), but prolonged, continuous exposure leads to desensitization of pituitary gonadotropes, thereby suppressing sex steroid production .
The primary target of triptorelin is the gonadotropin-releasing hormone receptor (GnRHR). It acts as a potent agonist, binding to the GnRHR and initially stimulating the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. This initial stimulation is followed by a paradoxical downregulation of the receptor, leading to a suppression of gonadotropin secretion and a subsequent decrease in sex hormone production (testosterone in men and estradiol in women). This reversible suppression of the hypothalamic-pituitary-gonadal axis is the basis for its therapeutic effects in hormone-dependent conditions.
体外研究 (In Vitro)
曲普瑞林对雷公藤多糖苷诱导的小鼠卵巢细胞功能损伤具有保护作用[2]。在培养的人颗粒黄体化(hGL)细胞中,曲普瑞林(1 nM 和 3 nM,处理 48 小时)可使细胞活力略微增加约 4-10%,与未处理的对照组相比。虽然两种浓度均未显著影响雌二醇的分泌,但 3 nM 曲普瑞林处理的细胞培养物中雌二醇水平低于对照组,且与 1 nM 西曲瑞克处理的细胞相比,差异具有统计学意义。两种浓度的曲普瑞林均可使孕酮水平略微降低,但差异无统计学意义(3 nM 时降低约 10%)。其他研究表明,曲普瑞林可抑制DU145、LNCaP、PC3前列腺癌细胞和OVCAR-3卵巢癌细胞的生长。
体外实验表明,曲普瑞林能以高亲和力与GnRHR结合,并刺激培养的垂体细胞释放LH和FSH。在表达GnRHR的细胞中进行的细胞实验表明,该化合物可激活下游信号通路,包括磷脂酶C和MAPK通路。此外,该化合物还被证实能抑制雌二醇诱导的癌细胞增殖。这些体外研究证实了该化合物作为GnRH激动剂的作用机制。
体内研究 (In Vivo)
曲普瑞林对雷公藤多糖苷诱导的雌性小鼠卵巢功能损伤具有保护作用[2]。
在Sprague-Dawley雄性大鼠中,皮下注射醋酸曲普瑞林二氧化硅缓释制剂后的体内药代动力学研究表明,其Cmax值比参考产品帕莫瑞林®低5倍,且具有相似的缓释特性。在为期91天的研究期间,该缓释制剂可维持可检测的曲普瑞林血浆浓度,同时睾酮血浆水平在相同时间内保持在去势水平以下。在临床试验中,通过GnRH或GnRH激动剂刺激试验、基础LH水平或血清性激素浓度来监测曲普瑞林治疗中枢性性早熟的疗效。
在体内,曲普瑞林可有效降低性激素水平并治疗激素依赖性疾病。在晚期前列腺癌患者中,它可将睾酮水平降低至去势水平,从而抑制肿瘤生长。在子宫内膜异位症中,它能降低雌二醇水平,从而使子宫内膜异位病灶消退。在中枢性性早熟中,它能阻止青春期发育进程。该化合物以缓释注射剂的形式给药,可长期抑制下丘脑-垂体-性腺轴。
酶活实验
曲普瑞林在促性腺激素释放激素(GnRH)受体上的活性通常使用无细胞体系中的放射性配体结合试验进行评估。将表达GnRH受体的细胞膜制备物与放射性标记的曲普瑞林或GnRH类似物以及不同浓度的未标记曲普瑞林孵育。通过过滤或离心分离结合的和游离的放射性配体,并测量放射性以计算IC₅₀或Kd值。
曲普瑞林的体外酶或受体结合(非细胞)试验包括研究其与GnRHR的结合亲和力。放射性配体结合试验使用表达GnRHR的细胞膜制备物进行。将化合物与放射性标记的配体孵育,并测量配体的置换情况以确定Ki或IC50值。这些试验证实了化合物对GnRHR的高亲和力。功能性试验,例如测量肌醇磷酸酯的生成,用于评估其激动剂活性。
细胞实验
从接受体外受精(IVF)治疗的女性中采集人颗粒黄体化(hGL)细胞,并以20,000个活细胞/孔的密度接种于96孔板中。将细胞置于含6%胎牛血清、2% Ultroser G、100 IU/ml青霉素和100 ng/ml链霉素的RPMI-1640培养基中,在37°C、5% CO₂条件下培养48小时以恢复细胞功能。随后,将细胞置于无血清培养基中,分别用1 nM或3 nM曲普瑞林处理48小时。采用 MTT 法评估细胞活力:向每个孔中加入 10 μl MTT 溶液(5 mg/ml,溶于无菌 PBS),于 37°C 孵育 4 小时,然后加入 100 μl 含 10% SDS 和 50% DMF(pH 4.7)的溶剂缓冲液,于室温避光孵育 10-20 小时。在 595 nm 波长处测量光密度值。采用 ELISA 法测定培养上清液中雌二醇和孕酮的浓度。
使用垂体细胞或表达 GnRHR 的细胞系进行曲普瑞林的体外细胞实验。用该化合物处理细胞,并通过 ELISA 或放射免疫分析法测定 LH 和 FSH 的释放。通过测量细胞内钙离子水平或 MAPK 磷酸化水平来评估下游信号通路的激活情况。使用癌细胞系评估该化合物对细胞增殖的影响。
动物实验
对于合格、健康的SD雌性小鼠,采用阴道脱落细胞法选取30只具有正常动情周期的小鼠作为实验动物,随机分为3组,每组10只:• A组:空白对照组,每日灌胃0.35 mL生理盐水,持续11周;• B组:雷公藤苷组,自第8天起每日灌胃0.35 mL雷公藤苷溶液,持续10周;• C组:雷公藤内酯醇+曲普瑞林组:每日皮下注射0.1 mg/kg曲普瑞林,持续11周;自第8天起每日灌胃0.35 mL雷公藤内酯醇溶液,持续10周。从实验第一天起,观察并记录小鼠的一般状况,包括精力、活动量、毛发状况、食物摄入量、饮水量、胃食欲、第二次排便等。每周称量小鼠体重,观察体重变化。采用操作简便的阴道脱落细胞法观察动情周期。治疗11周后,停药3周,处死所有小鼠。随后通过剖腹手术取出卵巢,并使用电子分析天平称量卵巢湿重。卵巢指数的计算公式为:卵巢湿重(mg)/小鼠体重(g)×100%。称重后,将卵巢固定于4%多聚甲醛溶液中3天,然后按常规进行脱水、二甲苯透明、石蜡包埋、切片(4 µm)等步骤,并按照免疫组化试剂盒说明书进行操作。免疫组织化学平均光密度(平均光密度)分析方法:每组切片随机选取至少三个位置,以200倍视野(FoV)进行拍照。拍照时,选择视野范围以确保待测组织完全充满视野。此外,尽量保持每张照片的背景照明一致。使用Image-Pro Plus 6.0软件选择相同的棕黄色作为所有照片阳性结果的统一标准。分析每张照片以获得积分光密度(IOD)和像素面积(AREA)。平均光密度(AO)的计算公式为AO = IOD/AREA。(1)AO值越大,阳性表达水平越高。[2]
雄性Sprague-Dawley大鼠皮下注射曲普瑞林醋酸盐二氧化硅微粒缓释制剂。在91天的研究期间,于不同时间点采集血样。采用超高效液相色谱-串联质谱法 (UPLC-MS/MS) 分析曲普瑞林血浆浓度,并以睾酮浓度作为药效学终点进行评估。将缓释制剂的药代动力学和药效学特征与参考产品帕莫瑞林® LA 进行比较。对于中枢性性早熟的治疗,由医护人员每 24 周肌注一次 22.5 mg 曲普瑞林。
曲普瑞林的体内动物实验采用啮齿动物模型进行。给予该化合物后,评估其对性激素水平、生殖功能和肿瘤生长的影响。在前列腺癌模型中,测量肿瘤体积。在子宫内膜异位症模型中,评估子宫内膜异位症病灶的大小。此外,还评估该化合物对动情周期和生育能力的影响。
药代性质 (ADME/PK)
吸收、分布和排泄
曲普瑞林静脉注射后可完全吸收。曲普瑞林主要经肾脏和肝脏排泄。健康男性单次静脉注射0.5 mg曲普瑞林后,曲普瑞林肽的分布容积为30-33 L。健康男性志愿者曲普瑞林的总清除率为211.9 mL/min。代谢/代谢物 曲普瑞林在人体内的代谢机制尚未完全阐明;然而,其代谢可能不涉及细胞色素P450等肝酶。关于曲普瑞林是否以及如何影响其他代谢酶知之甚少。曲普瑞林没有已知的代谢物。生物半衰期 曲普瑞林的药代动力学符合三室模型。其估计半衰期分别为 6 分钟、45 分钟和 3 小时。
由于第 6 位 D-色氨酸取代,曲普瑞林与天然 GnRH 相比,具有更高的受体结合亲和力和更长的血浆半衰期。其药效学特征呈双相模式:初始刺激垂体促性腺激素(LH 和 FSH)分泌,随后受体持续下调,导致性腺性激素生成受到抑制,雄性睾酮水平降至去势水平。在大鼠中,醋酸曲普瑞林的二氧化硅缓释制剂表现出缓释特性,在 91 天的研究期间维持可检测的血浆浓度。对于中枢性性早熟,曲普瑞林每 24 周肌注 22.5 mg。
曲普瑞林的药代动力学 (PK) 特性以其快速的初始分布和缓释制剂的持续释放为特征。该化合物的分子量为1311.45,分子式为C64H82N18O13。它是一种肽类药物,以缓释注射剂的形式给药,可在数周或数月内持续释放。该化合物经肽酶代谢,并通过肾脏排泄。缓释制剂的长半衰期使其可以每月一次或每三个月一次给药。
毒性/毒理 (Toxicokinetics/TK)
肝毒性
长期使用曲普瑞林可导致 2% 至 5% 的患者出现血清酶升高,但升高幅度很少超过正常上限的三倍(概率评分:E(不太可能是造成临床显著肝损伤的原因))。蛋白结合:曲普瑞林在临床相关浓度下不与血浆蛋白结合。
根据对 FDA 不良事件报告系统 (FAERS) 数据库(2004 年第一季度至 2024 年第三季度)的药物警戒分析,在 4,018 份以曲普瑞林为主要怀疑药物的报告中,最常见的不良反应包括血管舒缩症状(尤其是潮热,>70%)、性功能障碍、头痛、情绪变化和注射部位反应。警告和注意事项包括:由于初始刺激作用导致性激素水平升高、精神事件(例如情绪不稳、易怒、愤怒、攻击性)、惊厥、严重皮肤不良反应和假性脑瘤。根据FAERS数据,不良事件的中位发生时间为132天(四分位距36-361天),呈双峰分布:22.59%发生在第一个月内,25.07%发生在一年后。曲普瑞林禁用于妊娠期或对GnRH激动剂或制剂中任何成分过敏的患者。曲普瑞林的毒理学数据表明,其总体耐受性良好。最常见的副作用与性激素水平的初始激增(爆发现象)以及随后的性激素抑制有关。这种药物的刺激反应可能导致症状暂时加重,例如前列腺癌患者的骨痛。长期抑制性激素会导致潮热、性欲减退、骨质疏松以及其他性腺功能减退的症状。该化合物在妊娠期禁用。

其他信息
曲普瑞林是一种寡肽,由焦谷氨酰、组氨酸、色氨酸、丝氨酸、酪氨酸、D-色氨酸、亮氨酸、精氨酸、脯氨酸和甘氨酸残基按顺序连接而成。它是促性腺激素释放激素 (LHRH) 的激动剂类似物。曲普瑞林可用作 LHRH 激动剂、抗肿瘤药物和避孕药。曲普瑞林是一种合成的十肽,也是 LHRH 的激动剂类似物。曲普瑞林比内源性 LHRH 更有效,并可逆性地抑制促性腺激素的分泌。长期连续给药可持续降低 LH 和 FSH 的产生,以及睾丸和卵巢中类固醇的产生。血清睾酮浓度可能降低至通常在接受手术去势的男性中观察到的水平。曲普瑞林是一种促性腺激素释放激素 (GnRH) 激动剂,可强效抑制男性睾酮和女性雌激素的合成,用于治疗晚期前列腺癌。曲普瑞林治疗期间血清酶短暂升高的发生率较低,但尚无确凿证据表明其与具有临床意义的急性肝损伤病例相关。曲普瑞林是一种合成的十肽促黄体生成素释放激素 (LHRH) 激动剂类似物。曲普瑞林比内源性 LHRH 更有效,可逆性抑制促性腺激素的分泌。长期连续用药可持续降低促黄体生成素 (LH) 和促卵泡激素 (FSH) 的产生,以及睾丸和卵巢中的类固醇激素生成。血清睾酮浓度可能降低至通常在接受手术去势的男性中观察到的水平。 (NCI04)

药物适应症

FDA标签
用于断奶母猪的排卵同步化,以便进行单次定时人工授精。
作用机制
曲普瑞林是促性腺激素释放激素 (GnRH) 的合成激动剂类似物。动物研究比较了曲普瑞林与天然促性腺激素释放激素 (GnRH),结果表明曲普瑞林释放的黄体生成素是天然GnRH的13倍,卵泡刺激素是天然GnRH的21倍。
药效学
首次使用曲普瑞林后,体内会出现卵泡刺激素 (FSH)、黄体生成素 (LH)、雌二醇和睾酮的短暂激增。睾酮在体内的出现时间、峰值和下降速度取决于给药剂量。这种初始激增通常会加剧前列腺癌的早期症状,例如尿道或膀胱出口梗阻、骨痛、脊髓损伤和血尿。通常,在开始治疗 2-4 周后,FSH 和 LH 水平会逐渐下降,睾酮生成也会显著减少。最终,血清睾酮水平会下降到与接受手术去势的男性相似的水平。最终,需要这些激素的组织和功能会变得不活跃。曲普瑞林的作用通常在停药后消失。

假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀/澄清;向上述体系中加入50 μL Tween-80,混合均匀/澄清;然后继续加入450 μL ddH2O (或 saline)定容至 1 mL;

3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出,可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果,工作液请现配现用!
6、如不确定怎么将母液配置成体内动物实验的工作液,请查看说明书或联系我们;
7、 以上所有助溶剂都可在 Invivochem.cn网站购买。
制备储备液 1 mg 5 mg 10 mg
1 mM 0.7625 mL 3.8126 mL 7.6251 mL
5 mM 0.1525 mL 0.7625 mL 1.5250 mL
10 mM 0.0763 mL 0.3813 mL 0.7625 mL

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;

2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;

3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);

4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。

计算器

摩尔浓度计算器可计算特定溶液所需的质量、体积/浓度,具体如下:

  • 计算制备已知体积和浓度的溶液所需的化合物的质量
  • 计算将已知质量的化合物溶解到所需浓度所需的溶液体积
  • 计算特定体积中已知质量的化合物产生的溶液的浓度
使用摩尔浓度计算器计算摩尔浓度的示例如下所示:
假如化合物的分子量为350.26 g/mol,在5mL DMSO中制备10mM储备液所需的化合物的质量是多少?
  • 在分子量(MW)框中输入350.26
  • 在“浓度”框中输入10,然后选择正确的单位(mM)
  • 在“体积”框中输入5,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案17.513 mg出现在“质量”框中。以类似的方式,您可以计算体积和浓度。

稀释计算器可计算如何稀释已知浓度的储备液。例如,可以输入C1、C2和V2来计算V1,具体如下:

制备25毫升25μM溶液需要多少体积的10 mM储备溶液?
使用方程式C1V1=C2V2,其中C1=10mM,C2=25μM,V2=25 ml,V1未知:
  • 在C1框中输入10,然后选择正确的单位(mM)
  • 在C2框中输入25,然后选择正确的单位(μM)
  • 在V2框中输入25,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案62.5μL(0.1 ml)出现在V1框中
g/mol

分子量计算器可计算化合物的分子量 (摩尔质量)和元素组成,具体如下:

注:化学分子式大小写敏感:C12H18N3O4  c12h18n3o4
计算化合物摩尔质量(分子量)的说明:
  • 要计算化合物的分子量 (摩尔质量),请输入化学/分子式,然后单击“计算”按钮。
分子质量、分子量、摩尔质量和摩尔量的定义:
  • 分子质量(或分子量)是一种物质的一个分子的质量,用统一的原子质量单位(u)表示。(1u等于碳-12中一个原子质量的1/12)
  • 摩尔质量(摩尔重量)是一摩尔物质的质量,以g/mol表示。
/

配液计算器可计算将特定质量的产品配成特定浓度所需的溶剂体积 (配液体积)

  • 输入试剂的质量、所需的配液浓度以及正确的单位
  • 单击“计算”按钮
  • 答案显示在体积框中
动物体内实验配方计算器(澄清溶液)
第一步:请输入基本实验信息(考虑到实验过程中的损耗,建议多配一只动物的药量)
第二步:请输入动物体内配方组成(配方适用于不溶/难溶于水的化合物),不同的产品和批次配方组成不同,如对配方有疑问,可先联系我们提供正确的体内实验配方。此外,请注意这只是一个配方计算器,而不是特定产品的确切配方。

DMSO母液配制方法 mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。

体内配方配制方法μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。

(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
            (2) 一定要按顺序加入溶剂 (助溶剂) 。
