产品描述
替格瑞洛(以前称为 AZD-6140;AR-C 126532XX;AZD6140;AR-C126532XX;商品名:Brilinta;Brilique;Possia)是第一个可逆结合、有效且具有口服生物活性的 P2Y12 受体拮抗剂,用作抗血小板和抗凝剂。它抑制 P2Y12 受体,Ki 为 2 NM。替格瑞洛于 2011 年被 FDA 批准作为一种抗血小板药物,用于预防急性冠状动脉综合征(即冠状动脉血液供应问题)患者的中风、心脏病发作和其他事件。与噻吩并吡啶类普拉格雷、氯吡格雷和噻氯匹定一样,替格瑞洛可阻断 P2Y12 亚型的腺苷二磷酸 (ADP) 受体。与其他抗血小板药物相比,替格瑞洛具有与 ADP 不同的结合位点,使其成为变构拮抗剂,并且阻断是可逆的。
生物活性&实验参考方法
靶点
The targets of Ticagrelor (AZD6140) are the P2Y12 receptor (Ki = 3.2 nM, human recombinant P2Y12 receptor) and the ENT1 transporter (IC50 = 0.8 μmol/L, human erythrocyte ENT1 transporter) [1]
体外研究 (In Vitro)
与其他 P2Y12R 拮抗剂相比,替格瑞洛可更好地抑制缺血性血小板中 5'-二磷酸腺苷 (ADP) 诱导的 Ca2+ 释放。除了对 P2Y12R 的拮抗作用外,替格瑞洛还抑制血小板上的平衡核苷转运蛋白 1 (ENT1),从而导致细胞外腺苷积累和 Gs 偶联腺苷 A2A 受体被激活[1]。与用盐水治疗的小鼠相比,B16-F10 细胞与用替格瑞洛治疗的小鼠的血小板的相互作用较少[2]。
人富血小板血浆实验中,Ticagrelor (AZD6140) 以浓度依赖性抑制 ADP 诱导的血小板聚集,1 μmol/L 浓度下抑制率可达 90% 以上,且作用具有可逆性,停药后血小板功能可快速恢复 [1][3]
- 重组 P2Y12 受体实验中,Ticagrelor (AZD6140) 表现为反向激动活性,可抑制受体基础活性,降低细胞内 cAMP 水平,该效应独立于 ADP 结合 [1]
- 人红细胞实验中,Ticagrelor (AZD6140) 可阻断 ENT1 转运体介导的腺苷摄取,0.5 μmol/L 浓度下腺苷摄取抑制率达 80%,进而升高胞外腺苷浓度,增强腺苷介导的抗血小板效应 [1]
- 人乳腺癌(MDA-MB-231)、肺癌(A549)细胞体外实验中,Ticagrelor (AZD6140) 可抑制细胞迁移和侵袭,10 μmol/L 浓度下迁移能力下降 50% 以上,且可下调基质金属蛋白酶(MMP-2、MMP-9)的表达 [2]
- 大鼠富血小板血浆实验中,Ticagrelor (AZD6140) 对 ADP 诱导的血小板聚集的抑制强度与普拉格雷相当,但起效更快,100 nmol/L 浓度下 5 分钟内即可达到最大抑制效果 [3]
体内研究 (In Vivo)
在 B16-F10 黑色素瘤静脉内和脾内转移模型中,给予治疗剂量的替格瑞洛(10 mg/kg)的小鼠显示肺(84%)和肝(86%)转移显着减少。此外,用替格瑞洛治疗的动物比用盐水治疗的动物有更高的存活率。在 4T1 乳腺癌模型中也看到了类似的结果,其中替格瑞洛治疗减少了肺 (55%) 和骨髓 (87%) 转移[2]。口服替卡格雷(1-10 mg/kg)一次对血小板聚集具有剂量相关的抑制作用。当替格瑞洛最大剂量为10 mg/kg时,血小板聚集在用药后一小时开始受到显着抑制,并在四小时后达到峰值[3]。
小鼠乳腺癌(4T1)和肺癌(LLC)转移模型中,口服给予 Ticagrelor (AZD6140)(10、30 mg/kg,每日 2 次,持续 21 天)可剂量依赖性减少肺部转移灶数量,30 mg/kg 剂量下转移灶减少 60% 以上,同时延长小鼠生存期(中位生存期延长 30%-40%)[2]
- 大鼠 FeCl3 诱导颈动脉血栓模型中,口服 Ticagrelor (AZD6140)(1、3、10 mg/kg)可剂量依赖性延长血栓形成时间,10 mg/kg 剂量下血栓形成时间较对照组延长 2 倍以上;与普拉格雷(3 mg/kg)相比,两者抗血栓效果相当,但 Ticagrelor (AZD6140) 停药后止血功能恢复更快 [3]
- 大鼠出血模型中,Ticagrelor (AZD6140)(10 mg/kg)口服给药后,出血时间较对照组延长 1.5 倍,而普拉格雷(3 mg/kg)组出血时间延长 2 倍,提示 Ticagrelor (AZD6140) 出血风险相对更低 [3]
- 小鼠体内实验中,Ticagrelor (AZD6140) 可抑制肿瘤细胞与血小板的结合,减少循环肿瘤细胞的存活,进而抑制远处转移 [2]

药代性质 (ADME/PK)
吸收、分布和排泄
替格瑞洛的口服生物利用度为36%。单次口服200mg替格瑞洛后,其血药浓度峰值(Cmax)为923ng/mL,达峰时间(Tmax)为1.5小时,药时曲线下面积(AUC)为6675ng/mL。替格瑞洛的活性代谢物Cmax为264ng/mL,达峰时间(Tmax)为3.0小时,药时曲线下面积(AUC)为2538ng/mL。
放射性标记的替格瑞洛剂量有57.8%从粪便中回收,26.5%从尿液中回收。未代谢的母体药物回收率不足1%。活性代谢物AC-C124910XX占粪便回收量的21.7%。代谢物 AR-C133913XX 占尿液回收量的 9.2%,占粪便回收量的 2.7%。其他次要代谢物主要在尿液中回收。替格瑞洛的稳态分布容积为 88 L。替格瑞洛的肾清除率为 0.00584 L/h。该药物主要通过细胞色素 P-450 (CYP) 同工酶 3A4 代谢为一种活性代谢物,该代谢物具有与母体药物相似的抗血小板活性。替格瑞洛及其活性代谢物的血浆浓度呈剂量依赖性增加,分别在约 1.5 小时和 2.5 小时达到峰值浓度。替格瑞洛主要经粪便排泄,少量经尿液排泄;尿液中回收的药物(包括母体药物和活性代谢物)不足剂量的 1%。替格瑞洛及其活性代谢物均与人血浆蛋白广泛结合(结合率超过99%)。与高脂餐同服可使替格瑞洛的全身暴露量增加21%,并使活性代谢物的血浆峰浓度降低22%,但对替格瑞洛的血浆峰浓度或活性代谢物的全身暴露量无影响。
口服替格瑞洛后吸收迅速。
替格瑞洛的主要清除途径是肝脏代谢。当使用放射性标记的替格瑞洛时,放射性的平均回收率约为84%(粪便中58%,尿液中26%)。尿液中替格瑞洛及其活性代谢物的回收率均低于给药剂量的1%。替格瑞洛主要代谢物的排泄途径很可能是胆汁分泌。
/乳汁/ 尚不清楚替格瑞洛或其活性代谢物是否会分泌到人乳中。替格瑞洛会分泌到大鼠乳汁中。
有关替格瑞洛(共6种代谢物)的更多吸收、分布和排泄(完整)数据,请访问HSDB记录页面。
代谢/代谢物
所有替格瑞洛代谢物的完整结构尚未明确。替格瑞洛可在环戊烷环的5位脱烷基化,形成活性代谢物AR-C124910XX。AR-C124910XX的环戊烷环可进一步发生葡萄糖醛酸化,或与硫原子相连的烷基链可发生羟基化。替格瑞洛也可发生葡萄糖醛酸化或羟基化。替格瑞洛也可经N-去烷基化生成AR-C133913XX,后者可进一步发生葡萄糖醛酸化或羟基化。
CYP3A4是负责替格瑞洛代谢及其主要活性代谢物生成的主要酶。替格瑞洛及其主要活性代谢物均为弱P-糖蛋白底物和抑制剂。活性代谢物的全身暴露量约为替格瑞洛暴露量的30-40%。
该药物主要通过细胞色素P-450 (CYP) 同工酶3A4代谢为活性代谢物,该代谢物与母体药物具有相似的抗血小板活性。
替格瑞洛是一种可逆性结合的口服P2Y12受体拮抗剂,目前正在开发用于预防急性冠脉综合征患者的血栓事件。本研究在6名健康男性受试者中,单次口服200 mg (14)C-替格瑞洛混悬液,持续168小时,考察了替格瑞洛的药代动力学、代谢和排泄情况。……血浆和粪便中的主要循环成分被鉴定为替格瑞洛和AR-C124910XX,而尿液中的主要成分是代谢物M5 (AR-C133913XX)及其葡萄糖醛酸苷结合物M4。尿液中原形替格瑞洛和AR-C124910XX的含量均低于0.05%,表明替格瑞洛和AR-C124910XX的肾清除率很低。尿液和粪便提取物的个体间差异均较小,仅存在少量定量差异。所有10种代谢物均已完全或部分表征,并提出了替格瑞洛的完整生物转化途径。在该途径中,替格瑞洛羟乙基侧链的氧化丢失形成AR-C124910XX,而第二条氧化途径导致替格瑞洛的N-去烷基化,形成AR-C133913XX。
生物半衰期
替格瑞洛的血浆半衰期约为8小时,而其活性代谢物的血浆半衰期约为12小时。
据报道,替格瑞洛及其活性代谢物的平均终末半衰期分别约为7小时和9小时。

- 排泄:代谢产物主要经粪便(约60%)排泄,部分经肾脏(约30%)排泄,在大鼠体内半衰期(t1/2)约为2-3小时[3]
毒性/毒理 (Toxicokinetics/TK)
毒性概述
识别和用途:替格瑞洛为结晶性粉末。作为药物倍林达(Brilinta),它适用于降低急性冠脉综合征(ACS)或有心肌梗死(MI)病史患者的心血管死亡、心肌梗死和卒中发生率。倍林达还能降低接受支架植入治疗ACS患者的支架内血栓形成率。人体暴露和毒性:过量服用症状可能包括出血、胃肠道反应(恶心、呕吐和腹泻)以及心室停搏。失血是主要风险。动物研究:该药物的急性毒性被认为较低。在小鼠和大鼠中进行的单剂量研究结果表明,以mg/kg为单位,灌胃给予替格瑞洛剂量约为推荐人日剂量的550倍时,耐受性良好。在小鼠、大鼠和狨猴中进行了重复给药研究。所有物种均观察到亚临床出血的迹象。啮齿动物在高剂量下出现肝脏重量增加。在剂量高达60 mg/kg/天(相当于人治疗暴露量的4.6倍)时,替格瑞洛对大鼠的分娩或产后发育无影响,但在180 mg/kg剂量下,对幼鼠的母体和发育毒性有影响。在器官形成期,大鼠口服剂量高达100 mg/kg/天(相当于人治疗暴露量的5.1倍)以及兔子口服剂量高达42 mg/kg/天(相当于人治疗暴露量)时,替格瑞洛对胎儿发育无影响。替格瑞洛及其活性代谢物AR-C124910XX在体外细菌试验、体外小鼠淋巴瘤L5178Y TK+/- 3.7.2C细胞试验以及体内大鼠骨髓微核试验中均未显示出任何遗传毒性。
肝毒性
在多项大型临床试验中,替格瑞洛治疗期间未出现血清酶升高,也未报告任何临床上明显的肝损伤病例。虽然有个别病例报告在替格瑞洛治疗期间出现短暂且轻微的血清酶升高,但这些升高持续时间短且无症状。此外,自上市以来,尚未有与替格瑞洛治疗相关的孤立性临床上明显的肝损伤或黄疸病例报告,且产品标签中也未提及肝毒性。另一方面,已有数例黄疸和肝损伤的报道,这些黄疸和肝损伤与横纹肌溶解症和血栓性血小板减少性紫癜相关,代表了这些严重不良事件的继发效应。因此,替格瑞洛可导致显著的肝损伤,但这种情况大多与其他危及生命的并发症同时发生。
可能性评分:D(可能是严重过敏反应或药物相互作用并发症导致肝损伤的罕见原因)。
妊娠和哺乳期影响
◉ 哺乳期用药概述
目前尚无关于哺乳期使用替格瑞洛的公开信息。由于替格瑞洛及其活性代谢物与血浆蛋白的结合率超过99%,因此其在乳汁中的含量可能很低。但是,尤其是在哺乳新生儿或早产儿时,可能更倾向于选择其他药物。如果哺乳期母亲使用本品,请密切观察婴儿是否有瘀伤和出血。
◉ 对母乳喂养婴儿的影响
截至修订日期,未找到相关的已发表信息。
◉ 对泌乳和母乳的影响
截至修订日期,未找到相关的已发表信息。
蛋白结合
替格瑞洛及其活性代谢物在血浆中的蛋白结合率>99%,尤其是白蛋白。
相互作用
替格瑞洛与地高辛合用不会显著影响地高辛的药代动力学;因此,这两种药物可以同时使用,无需调整剂量。然而,由于P-糖蛋白抑制可能导致地高辛浓度升高,因此在开始使用替格瑞洛治疗期间以及任何治疗方案改变后,均应监测血清地高辛浓度。
当替格瑞洛与每日维持剂量超过100 mg的阿司匹林联合使用时,替格瑞洛的疗效可能会降低。
替格瑞洛是P-糖蛋白转运系统的底物和弱抑制剂。当这些药物与替格瑞洛同时使用时,P-糖蛋白底物(例如地高辛)的血清浓度可能会升高;建议进行适当的实验室和/或临床监测。
替格瑞洛与利福平600 mg每日一次联合用药会显著降低替格瑞洛的血浆峰浓度和全身暴露量。因此,应避免同时使用替格瑞洛和利福平。

体内毒性:大鼠连续3天口服最大剂量10 mg/kg的替格瑞洛(AZD6140)后,未观察到明显的体重减轻、行为异常或肝肾功能指标(ALT、AST、BUN、Cr)升高[3]
- 出血风险:替格瑞洛(AZD6140)可轻微延长出血时间,但在等效抗血栓剂量下,其出血风险低于普拉格雷[3]
- 血浆蛋白结合率:大鼠血浆蛋白结合率为97%-98%,人血浆蛋白结合率约为99%[3]体外毒性:在 100 μmol/L 浓度下,对人血小板和肿瘤细胞无明显细胞毒性,细胞存活率高于 90% [1][2]

Brilinta还可降低接受支架植入治疗急性冠脉综合征(ACS)患者的支架内血栓形成率。/美国产品标签包含/
药物警告
/黑框警告/出血风险。Brilinta与其他抗血小板药物一样,可能导致严重甚至致命的出血。对于有活动性病理性出血或颅内出血病史的患者,禁用Brilinta。对于正在接受紧急冠状动脉旁路移植术(CABG)的患者,禁用Brilinta。如果可能,应在不停用倍林达(Brilinta)的情况下控制出血。停用倍林达会增加后续心血管事件的风险。
/黑框警告/ 阿司匹林剂量与倍林达疗效。维持剂量超过 100 mg 的阿司匹林会降低倍林达的疗效,应避免使用。
通常情况下,不应过早停用替格瑞洛治疗,因为这会增加心血管事件的风险。对于冠状动脉支架植入患者,过早停用抗血小板治疗(例如,P2Y12 腺苷二磷酸 (ADP) 受体拮抗剂、阿司匹林)与缺血性心血管事件(例如,支架血栓形成、心肌梗死 (MI)、死亡)风险增加相关。如果必须暂时停用替格瑞洛,例如在择期手术前或为了控制出血,应尽快重新开始用药。应告知患者,即使其他临床医生(例如牙医)指示停止服用替格瑞洛,也切勿在未咨询处方医生的情况下擅自停药。在安排侵入性操作前,患者应告知临床医生(包括牙医)其目前正在服用替格瑞洛,执行侵入性操作的临床医生在停止服用替格瑞洛前应咨询处方医生。
服用替格瑞洛的患者曾出现过缓慢性心律失常,包括室性停搏。在血小板抑制与患者预后研究(PLATO)中,接受替格瑞洛治疗的患者在治疗第一周内,动态心电图监测检测到的至少3秒的室性停搏发生率高于接受氯吡格雷治疗的患者(分别为5.8%和3.6%)。两组患者发生具有临床意义的缓慢性心律失常(例如晕厥、需要植入起搏器)的总体风险无差异。室性停搏大多无症状,归因于窦房结抑制。PLATO 研究排除了基线心动过缓风险增加的患者(例如,病态窦房结综合征、二度或三度房室传导阻滞、未植入起搏器但因心动过缓引起的晕厥患者);因此,一些临床医生建议对这类患者谨慎使用替格瑞洛。

药效学
替格瑞洛是一种 P2Y12 受体拮抗剂,可抑制血栓形成,从而降低心肌梗死和缺血性卒中的风险。由于每日两次给药,其作用持续时间适中;由于单次高剂量耐受性良好,其治疗指数较宽。应告知患者出血、呼吸困难和心动过缓的风险。
替格瑞洛 (AZD6140) 是一种可逆性 P2Y12 受体拮抗剂,同时具有 ENT1 转运体阻断活性,通过双重机制发挥抗血小板作用 [1]
- 它与 P2Y12 受体的结合是可逆的,停药后血小板功能可以迅速恢复。与不可逆拮抗剂(如普拉格雷和氯吡格雷)相比,替格瑞洛具有出血风险低、停药后止血功能恢复快的优势[3]。除了抗血小板作用外,替格瑞洛(AZD6140)还能通过抑制肿瘤细胞迁移、侵袭和肿瘤细胞-血小板相互作用,在小鼠癌症模型中发挥抗转移作用,提示其具有潜在的抗癌应用价值[2]。临床上,替格瑞洛主要用于治疗急性冠脉综合征等血栓性疾病,以降低心血管事件的风险。其独特的双重作用机制和可逆结合特性使其在临床用药中具有灵活的调整空间[1][3]。

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。
