动物实验
在携带DMS-53肺癌异种移植瘤的裸鼠中,地拉罗司抑制了肿瘤生长。此外,地拉罗司增加了裂解型caspase-3、裂解型聚(ADP-核糖)聚合酶1、细胞周期蛋白依赖性激酶抑制剂p21CIP1/WAF1以及转移抑制蛋白N-myc下游调控基因1的表达,同时降低了细胞周期蛋白D1的表达,这表明地拉罗司是一种有效的抗肿瘤药物。在人源异种移植瘤模型中,地拉罗司显著抑制了肿瘤生长,这与铁水平的降低有关。
铁过载小鼠模型:将6-8周龄的C57BL/6小鼠(每组n=8)每周腹腔注射一次右旋糖酐铁(10 mg/kg),持续4周,以诱导铁过载。将地拉罗司(ICL 670)悬浮于 0.5% 羧甲基纤维素溶液中,以 50 mg/kg/天的剂量灌胃给药,持续 8 周。对照组给予溶剂。治疗结束后,采集血液样本以测定血清铁蛋白和血红蛋白水平;取肝脏和脾脏组织以定量分析铁含量。[1]
白血病异种移植模型:将 K562 细胞(5×10⁶ 个细胞/只)皮下注射到 6-8 周龄的裸鼠(每组 n=7)体内。当肿瘤体积达到约 150 mm³ 时,以 80 mg/kg/天的剂量灌胃给予地拉罗司(ICL 670),持续 21 天。每 3 天测量一次肿瘤体积(体积 = 长 × 宽² × 0.5)。对小鼠实施安乐死,收集肿瘤组织进行铁含量分析和TUNEL染色[2]

药代性质 (ADME/PK)
吸收、分布和排泄
口服混悬剂的地拉罗司片剂的绝对生物利用度(AUC)为静脉注射剂量的70%。
地拉罗司及其代谢物主要(占给药剂量的84%)经粪便排泄。地拉罗司及其代谢物的肾脏排泄量极少(占给药剂量的8%)。
14.37 ± 2.69 L
口服给药后,Exjade 被吸收,达峰时间(tmax)中位数约为1.5-4小时。单次给药后以及在稳态条件下,地拉罗司的Cmax和AUC均随剂量呈近似线性增加。多次给药后,地拉罗司的暴露量累积因子增加1.3-2.3倍。与静脉注射剂量相比,地拉罗司片剂口服混悬液的绝对生物利用度(AUC)为70%。地拉罗司的生物利用度(AUC)在与食物同服时有不同程度的增加。
……本研究评估了单次口服375 mg地拉罗司片剂与130 mg地拉罗司静脉输注的绝对生物利用度。由于这是首次使用地拉罗司静脉注射制剂进行人体研究,因此在正式研究阶段之前,先在3名受试者中进行了较低剂量(65 mg)的预试验,以评估静脉注射制剂的安全性和耐受性。正式研究阶段纳入了17名健康男性志愿者。每次给药后均测量地拉罗司的血浆浓度,并测定包括绝对口服生物利用度在内的药代动力学参数。地拉罗司片剂的绝对口服生物利用度为 70%(90% 置信区间,62%-80%)。地拉罗司的血浆清除率较低,为 3.53 (± 0.87) L/hr。地拉罗司的稳态分布容积 (V(ss)) 较小,为 14.37 (±2.69) L,表明其组织分布较少。
……本研究在健康志愿者和输血性血色素沉着症患者中考察了食物和进食时间对地拉罗司药代动力学的影响。在健康志愿者中,分别于高脂早餐或标准早餐前或与标准早餐同时服用单次口服剂量地拉罗司 (20 mg/kg) 后,评估了其生物等效性,并与空腹状态进行了比较。在患者中,分别于进食和空腹状态下,测定了单次口服剂量地拉罗司 (20 mg/kg) 后的生物利用度。这些数据表明,食物类型、膳食热量和脂肪含量会影响地拉罗司与食物同时摄入时的生物利用度。相反,如果地拉罗司在餐前至少30分钟服用,则不会出现这种情况。总之,建议地拉罗司在餐前至少30分钟服用。如果无法做到这一点,则应在餐前同一时间服用地拉罗司,以减少影响吸收的变异因素。
地拉罗司与血清白蛋白高度结合(约99%),几乎完全与血清白蛋白结合。在人体内,地拉罗司在血细胞中的分布比例为5%。地拉罗司在成人体内的稳态分布容积 (Vss) 为 14.37 ± 2.69 L。

代谢/代谢物
肝脏代谢。地拉罗司在人体内的 CYP450 催化(氧化)代谢似乎较少(约 8%)。葡萄糖醛酸化是地拉罗司的主要代谢途径,随后经胆汁排泄。
葡萄糖醛酸化是地拉罗司的主要代谢途径,随后经胆汁排泄。葡萄糖醛酸化产物可能在肠道内发生去结合,随后被重吸收(肠肝循环)。地拉罗司主要通过 UGT1A1 进行葡萄糖醛酸化,少量通过 UGT1A3 进行葡萄糖醛酸化。在人体内,地拉罗司的 CYP450 催化(氧化)代谢似乎较少(约 8%)。
……肾脏排泄仅占剂量的 8%,主要包括葡萄糖醛酸苷 M6。细胞色素 450 酶氧化代谢生成 M1 [5-羟基地拉罗司,推测由 CYP1A 催化] 和 M4(5'-羟基地拉罗司,由 CYP2D6 催化)的量较少(分别占剂量的 6% 和 2%)。直接和间接证据表明,地拉罗司代谢的主要途径是通过葡萄糖醛酸化生成代谢物M3(酰基葡萄糖醛酸苷)和M6(2-O-葡萄糖醛酸苷)。
...地拉罗司的代谢包括羧酸基团(酰基葡萄糖醛酸苷M3)和酚羟基的葡萄糖醛酸化,以及程度较低的细胞色素P450催化的羟基化。两种羟基化代谢物(M1 和 M2)被给予大鼠,结果表明它们对体内铁的清除没有显著贡献。
生物半衰期
口服给药后,平均消除半衰期为 8 至 16 小时。
口服给药后,平均消除半衰期 (t1/2) 为 8 至 16 小时。
在健康志愿者中,口服地拉罗司 (ICL 670) (10 mg/kg) 的口服生物利用度为 70%,给药后 4 小时血浆峰浓度 (Cmax) 为 8.5 μg/mL [1]。
地拉罗司 (ICL 670)在人体内的终末半衰期 (t1/2) 为 8 至 16 小时,在小鼠体内为 6 至 8 小时 [1]。
它广泛分布于各种组织中,在以下部位浓度最高:肝脏、脾脏和肾脏(富含铁的器官)[1]
代谢主要在肝脏进行,通过葡萄糖醛酸化(UGT1A9、UGT1A1)形成无活性的葡萄糖醛酸苷结合物[3]
约80%的剂量以葡萄糖醛酸苷代谢物的形式经粪便排出,10%经尿液排出,<5%以原药形式排出[1]
毒性/毒理 (Toxicokinetics/TK)
肝毒性
在地拉罗司的大型临床试验中,6%的患者出现血清转氨酶水平升高至正常值上限(ULN)5倍以上,其中1%至2%的患者因此停药。此外,还有数例地拉罗司治疗期间出现临床表现明显的肝损伤的个案报道,这些肝损伤通常较为严重,甚至危及生命。急性肝损伤的发生时间从开始服用地拉罗司后数天到数年不等,但大多数病例发生在1至3个月内。肝损伤的典型模式为肝细胞性或混合性,并伴有血清转氨酶水平显著升高。未见免疫过敏和自身免疫特征。停用地拉罗司后,患者通常能迅速恢复,但部分病例会出现进行性肝损伤和肝功能衰竭。由于铁过载患者通常合并基础肝病,因此叠加的急性肝细胞性损伤可能会增加急性肝功能衰竭的风险。地拉罗司的包装盒上有关于肝毒性的黑框警告,建议定期监测血清胆红素和转氨酶水平。
可能性评分:C(可能导致临床上明显的肝损伤)。
妊娠和哺乳期影响
◉ 哺乳期用药概述
地拉罗司似乎很少进入乳汁。尽管澳大利亚指南建议在服用地拉罗司期间不要进行母乳喂养,但这些指南是在一份病例报告发布之前发布的。该病例报告显示,一名患有β-地中海贫血的母亲在服用地拉罗司期间安全地进行了母乳喂养,并且未在母乳中检测到药物。然而,由于关于哺乳期使用地拉罗司的公开信息很少,因此建议监测婴儿的血清铁水平。
◉ 对母乳喂养婴儿的影响
一位患有β-地中海贫血的妇女在产后立即开始服用地拉罗司,剂量为每日2250毫克(35毫克/公斤),并纯母乳喂养她的婴儿。分别在产后第1天、第10天和第30天采集婴儿的血样。血清铁蛋白水平分别为190、218和96微克/升(正常范围22至275微克/升)。血清铁水平分别为101、77和71微克/分升(正常范围60至170微克/分升)。婴儿出生后第一个月生长发育正常,处于第41百分位。
◉ 对哺乳和母乳的影响
截至修订日期,未找到相关的已发表信息。
蛋白结合
地拉罗司的蛋白结合率很高(约99%),几乎完全与血清白蛋白结合。
药物相互作用
同时使用UGT诱导剂或考来烯胺会降低地拉罗司的全身暴露量(AUC)。避免将考来烯胺或强效UGT诱导剂(例如利福平、苯妥英钠、苯巴比妥、利托那韦)与Exjade同时使用。如果必须同时使用这些药物,请考虑将Exjade的初始剂量增加至30 mg/kg,并监测血清铁蛋白水平和临床反应,以便进一步调整剂量。
Exjade与含铝抗酸剂同时服用尚未进行正式研究。尽管地拉罗司对铝的亲和力低于对铁的亲和力,但请勿将Exjade与含铝的抗酸剂同时服用。
在为期28天的大鼠亚慢性毒性研究中,地拉罗司(ICL 670)以高达200 mg/kg/天的剂量(口服)引起轻度胃肠道毒性(腹泻、食欲减少)和血清ALT/AST短暂升高(升高1.5倍),停药后恢复正常[1]
临床试验报告的常见不良事件包括:恶心(35%)、腹泻(28%)、腹痛(22%)和皮疹(18%),大多为轻度至中度[3]
在治疗剂量(10-30 mg/kg/天)下,严重毒性(严重肝损伤、肾衰竭)罕见(<2%的患者)[4]
血浆蛋白结合率地拉罗司(ICL 670)在人体中的有效率达99%[1]

治疗用途
铁螯合剂
Exjade(地拉罗司)适用于治疗2岁及以上患者因输血引起的慢性铁过载(输血性血铁沉积症)。在这些患者中,Exjade已被证实可降低肝脏铁浓度和血清铁蛋白水平。尚未完成证实其可提高生存率或确认临床获益的临床试验。/美国产品标签包含/
药物警告
/黑框警告/肾衰竭。Exjade可能导致急性肾衰竭和死亡,尤其是在合并其他疾病的患者以及处于血液系统疾病晚期的患者中。在开始治疗前,应测量血清肌酐并重复测定肌酐清除率,并在治疗后至少每月监测一次肾功能。对于基线肾功能受损或急性肾衰竭风险增加的患者,应在第一个月每周监测肌酐,之后至少每月监测一次。根据血清肌酐升高情况考虑减少剂量、暂停或停药。
/黑框警告/ 肝功能衰竭。Exjade 可导致肝损伤,包括肝功能衰竭和死亡。所有患者在开始治疗前、治疗后第一个月每 2 周以及之后至少每月均应检测血清转氨酶和胆红素水平。对于重度(Child-Pugh C 级)肝功能损害患者,应避免使用 Exjade;对于中度(Child-Pugh B 级)肝功能损害患者,应降低剂量。
/黑框警告/ 胃肠道出血。Exjade 可导致胃肠道出血,这可能致命,尤其是在患有晚期血液系统恶性肿瘤和/或血小板计数低的年长患者中。监测患者,若怀疑出现胃肠道溃疡或出血,应停止使用Exjade。
根据预期临床获益和治疗风险,并考虑患者的预期寿命和合并症等因素,个体化决定是否开始Exjade治疗。

药效学
地拉罗司是一种口服活性螯合剂,对铁(以Fe3+形式)具有选择性。它是一种三齿配体,以2:1的比例与铁高亲和力结合。尽管地拉罗司对锌和铜的亲和力很低,但在服用地拉罗司后,这些微量金属的血清浓度会出现不同程度的下降。这些下降的临床意义尚不明确。
地拉罗司 (ICL 670)是一种口服、每日一次的铁螯合剂,对 Fe³⁺ 的选择性远高于其他金属离子(例如 Zn²⁺、Cu²⁺)[1]
其核心作用机制是螯合不稳定的铁和与蛋白质(例如铁蛋白)结合的铁,形成稳定的水溶性复合物并排出体外,从而减少铁过载和铁介导的氧化应激[1]
临床上,它适用于治疗慢性输血引起的铁过载(例如地中海贫血、镰状细胞病)和非输血依赖性地中海贫血[4]
在临床前研究中,它通过消耗细胞增殖和 DNA 合成所需的铁,在铁依赖性癌症(白血病、结直肠癌)中表现出抗肿瘤活性[2][5]
已获 FDA 批准2005年,地拉罗司(ICL 670)获批用于治疗成人和2岁及以上儿童患者的慢性铁过载[3]

配方 4 中的溶解度: 5% DMSO + 40% PEG300 + 5% Tween 80 + 50% ddH2O: 3.7mg/ml (9.91mM)

请根据您的实验动物和给药方式选择适当的溶解配方/方案:
1、请先配制澄清的储备液(如:用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液,按从左到右的顺序依次添加助溶剂,澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明,并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
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 2.6783 mL 13.3915 mL 26.7831 mL
5 mM 0.5357 mL 2.6783 mL 5.3566 mL
10 mM 0.2678 mL 1.3392 mL 2.6783 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。

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) 。
