产品描述
Talazoparib(原名 BMN-673 和 MDV-3800;商品名:Talzenna)是一种新型高效 PARP1/2 [聚(ADP-核糖)聚合酶] 抑制剂,具有良好的代谢稳定性、口服生物利用度和药代动力学特性。作为一种新型 PARP 抑制剂,Talazoparib 在无细胞测定中的 IC50 为 0.58 nM。它选择性地结合 PARP,并通过碱基切除修复途径阻止 PARP 介导的单链 DNA 断裂的 DNA 修复。这会增强 DNA 链断裂的积累,促进基因组不稳定并最终导致细胞凋亡。 2018年10月16日,Talazoparib被FDA批准用于治疗具有种系BRCA突变的局部晚期或转移性乳腺癌患者。

体外研究 (In Vitro)
体外活性:BMN-673 选择性结合 PARP,并通过碱基切除修复途径阻止 PARP 介导的单链 DNA 断裂的 DNA 修复。这会增强 DNA 链断裂的积累,促进基因组不稳定并最终导致细胞凋亡。 BMN 673 选择性杀死具有 BRCA-1 或 BRCA-2 突变的癌细胞。 BMN 673 在 BRCA-1 突变体(MX-1,IC50 = 0.3 nM)和 BRCA-2 突变细胞(Capan-1,IC50 = 5 nM)中表现出单药细胞毒性。相比之下,在 MRC-5 正常人成纤维细胞和其他具有野生型 BRCA-1 和 BRCA-2 基因的肿瘤细胞系中,BMN 673 的 IC50 范围在 90 nM 至 1.9 μM 之间。在培养的人类癌细胞中,BMN 673 还显着增强替莫唑胺和 SN-38 的细胞毒性功效。脱靶分子筛选未发现此类 PARP 抑制剂具有显着的非特异性活性。激酶测定:对于 PARP 抑制剂 Ki 测定,在 96 孔 FlashPlate 中进行酶测定,最终体积中含有 0.5 U PARP1 酶、0.25x 活化 DNA、0.2 mCi [3H] NAD 和 5 mmol/L 冷 NAD(Sigma) 50 mL 反应缓冲液,含有 10% 甘油 (v/v)、25 mmol/L HEPES、12.5 mmol/L MgCl2、50 mmol/L KCl、1 mmol/L 二硫苏糖醇 (DTT) 和 0.01% NP-40 (v /v),pH 7.6。通过将 NAD 添加到含有或不含抑制剂的 PARP 反应混合物中来引发反应,并在室温下孵育 1 分钟。然后向每孔中加入50微升冰冷的20%三氯乙酸(TCA)以终止反应。将板密封并在室温下再摇动120分钟,然后离心。使用 Top-Count 确定与 FlashPlate 结合的放射性信号。 PARP1 Km 使用 Michaelis-Menten 方程从不同的底物浓度 (1-100 mmol/L NAD) 中确定。根据以下公式从酶抑制曲线计算化合物Ki:Ki 1/4 IC50/[1+(底物)/Km]。 PARP2 酶和化合物 Ki 的 Km 使用相同的测定方案测定,不同之处在于在室温下反应中使用 30 ng PARP2、0.25x 活化 DNA、0.2 mCi [3H] NAD 和 20 mmol/L 冷 NAD 30 分钟。细胞分析:BMN 673 对 11 种 SCLC 细胞系表现出有效的抑制作用(IC50=1.7 至 15 nmol/L),这些细胞系均在临床可达到的范围内。此外,对 BMN673 的敏感性与 DNA 修复蛋白表达和 PI3K 通路活性相关。
体内研究 (In Vivo)
在大鼠药代动力学研究中,BMN 673 显示出 >50% 的口服生物利用度和药代动力学特性,可实现每日单次给药。在 MX-1 异种移植肿瘤模型研究中,每日口服 BMN 673 可以剂量依赖性方式显着增强细胞毒性疗法的抗肿瘤作用。
BMN 673是易于口服的生物利用度,当给药于羧甲基纤维素时,大鼠的绝对口服生物利用度超过40%。口服bmn673在体内具有显著的抗肿瘤活性;携带BRCA突变或PTEN缺乏导致的DNA修复缺陷的异种移植肿瘤对小鼠耐受良好剂量的口服BMN 673治疗非常敏感。当BMN 673与替莫唑胺、SN38或铂类药物联合使用时,也发现了协同或附加的抗肿瘤作用。 结论:BMN 673目前处于早期临床开发阶段,是一种具有潜在优势的PARP1/2抑制剂。[1]
PARP抑制剂与免疫疗法的联合临床试验正在进行中,但PARP抑制剂的免疫调节作用尚未完全研究。在这里,我们试图剖析PARP抑制剂诱导brca1缺陷三阴性乳腺癌(TNBC)肿瘤微环境变化的机制。我们证明PARP抑制剂olaparib在体内诱导CD8+ t细胞浸润和活化,CD8+ t细胞耗损严重影响抗肿瘤效果。奥拉帕尼诱导的t细胞募集是通过激活肿瘤细胞中的cGAS/STING通路介导的,同时伴有旁分泌激活树突状细胞,并且在hr缺乏的TNBC细胞和体内模型中比hr精通的TNBC细胞更明显。crispr介导的敲除癌细胞中的STING可阻止促炎信号,并足以在体内消除奥拉帕尼诱导的t细胞浸润。这些发现阐明了PARP抑制剂的另一种作用机制,并为联合PARP抑制与免疫疗法治疗TNBC提供了理论依据。意义:本研究证实了PARP抑制与肿瘤微环境之间的串扰,这些微环境与肿瘤细胞中STING/TBK1/IRF3通路激活有关,从而调控CD8+ t细胞募集和抗肿瘤效果。这些数据为PARP抑制剂在brca相关乳腺癌中的作用机制提供了新的见解。[3]
酶活实验
为了确定 PARP 抑制剂 Ki,在 96 孔 FlashPlate 中使用 0.5 U PARP1 酶、0.25x 活化 DNA、0.2 mCi [3H] NAD 和 5 mmol/L 冷 NAD (Sigma) 在最终样品中进行酶测定。 50 mL 反应缓冲液,含有 10% 甘油 (v/v)、25 mmol/L HEPES、12.5 mmol/L MgCl2、50 mmol/L KCl、1 mmol/L 二硫苏糖醇 (DTT) 和 0.01% NP-40 (v/v),pH 7.6。将 NAD 添加到 PARP 反应混合物中(无论有或没有抑制剂)以启动反应,然后在室温下孵育一分钟。然后通过向每个孔中添加50微升冰冷的20%三氯乙酸(TCA)来终止反应。将板密封并在室温下另外摇动120分钟后,进行离心。 Top-Count 用于确定与 FlashPlate 结合的放射性信号。采用 Michaelis-Menten 方程计算不同底物浓度(1 至 100 mmol/L NAD)下的 PARP1 Km。使用公式 Ki 1/4 IC50/[1+(底物)/Km],从酶抑制曲线计算化合物 Ki。使用相同的测定方案,发现了 PARP2 酶的 Km 和化合物 Ki。然而,反应在室温下运行 30 分钟,而不是使用 30 ng PARP2、0.25x 活化 DNA、0.2 mCi [3H] NAD 和 20 mmol/L 冷 NAD。
PARP酶测定[1]
根据制造商的说明,使用Trevigen的PARP检测试剂盒评估测试化合物抑制PARP-1酶活性的能力。采用GraphPad Prism5软件计算IC50值。对于PARP抑制剂Ki的测定,酶分析在96孔FlashPlate上进行,0.5单位PARP1酶,0.25倍活化DNA, 0.2 μCi [3H] NAD和5 μM冷NAD,最终体积为50 μL反应缓冲液,含10%甘油(v/v), 25 mM Hepes, 12.5 mM MgCl2, 50 mM KCl, 1 mM DTT和0.01% NP-40(v/v), pH 7.6。将NAD加入到有或没有抑制剂的PARP反应混合物中,在室温下孵育1分钟,开始反应。然后在每孔中加入50 μL冰凉的20% TCA以停止反应。将板密封并在RT下振荡120分钟,然后离心。使用TopCount测定绑定到FlashPlate的放射性信号。采用Michaelis-Menten方程测定不同底物浓度(1-100 μM NAD)下PARP1 Km。根据酶抑制曲线计算化合物Ki,公式为:Ki = IC50/(1+[底物]/Km)。除30 ng PARP2、0.25x活化DNA、0.2 μCi [3H] NAD和20 μM冷NAD在室温下反应30min外,采用相同的检测方法测定PARP2酶Km和化合物Ki。
Biacore结合试验[1]
我们自制了带有n端6xhis标签的重组人PARP1 (rhPARP1)催化结构域(残基662 - 1011),并使用Biacore T200 (GE Healthcare)进行PARP抑制剂相互作用的结合试验。通过胺偶联法将rhPARP1固定在CM5传感器芯片上。简单地说,首先以10 μL/min的速率注射新鲜制备的50 mM NHS: 200 mM EDC(1:1),以10 μL/min的速度注射7 min,激活CM5芯片的一个流动细胞。然后以10 μL/min的速度将rhPARP1 (100 μg/mL, 10 mM MES pH 6.5)注射到流式细胞上60秒。以10 μL/min注射1M乙醇胺7 min阻断剩余活性偶联位点。固定化缓冲液含有10 mM Hepes pH 7.4, 150 mM NaCl, 0.05%表面活性剂P20, 5 mM MgCl2和0.5 mM TCEP(三(2-羧乙基)膦)。固定水平为~7600 RU。为了测量结合动力学,在芯片表面注射浓度增加的PARP抑制剂(12.5、25、50、100、200 nM),每次注射60秒。最后一次注射后,在运行缓冲液(固定缓冲液+ 1% DMSO)中进行3600秒的解离期。流速为50 μL/min。根据参考流的信号对传感器图进行校正后,使用Biacore T200评估软件ver.1.0计算动力学。
细胞内PAR形成试验[1]
细胞PAR合成试验评估了测试化合物抑制PAR聚合的能力。在96孔微滴板中生长的LoVo人结直肠肿瘤细胞在增加PARP抑制剂浓度的条件下预处理30分钟,然后加入终浓度为50 mM的H2O2。在室温下处理5分钟后,细胞在- 20°C下用预冷甲醇/丙酮(7:3)固定10分钟。固定细胞用抗par单克隆抗体孵育60 min,然后用FITC偶联山羊抗小鼠IgG(稀释1:100)和1 μg/mL DAPI孵育60 min,用DAPI信号归一化FITC信号,用GraphPad Prism计算EC50值。
细胞实验
一组 11 个 SCLC 细胞系(IC50=1.7 至 15 nmol/L),所有这些细胞系都在临床可行的范围内,证明了 BMN 673 的强大抑制作用。此外,PI3K 通路活性和 DNA 修复蛋白表达与 Talazoparib (BMN 673; MDV3800)  敏感性相关。
共焦显微镜[1]
细胞接种于6孔板盖盖上,24小时后用不同浓度的奥拉帕尼或Talazoparib (BMN 673; MDV3800) 处理24小时后,将细胞用10%福尔马林(3.7% PFA)固定1小时。用0.2% Triton X-100在PBS中渗透20分钟,用50 μL DNase I(在PBS中稀释1/10)在37℃下处理1小时,然后用IFF (PBS + 1% BSA和2% FBS,过滤灭菌)阻断1小时。盖片与兔抗γ - h2ax原代和小鼠抗rad51原代(均为1:1000,50μL IFF)在4°C下孵育过夜。次日,细胞与抗小鼠Alexafluor 546和抗兔Alexafluor 488(均为1:1000,50μL IFF)共孵育1小时。细胞在含DAPI 1:10.000的PBS中洗涤10分钟,用vectasshield和指甲油贴在玻璃板上。使用徕卡共聚焦显微镜对每个盖盖至少拍摄四张照片,随后对细胞进行计数。每次覆盖至少评估100个细胞,如果每个细胞核有超过5个病灶,则为γ - h2ax阳性。绘制阳性细胞的百分比。
动物实验
Xenograft experiments[1]
Female athymic nu/nu mice (8-10 week old) were used for all in vivo xenograft studies. Mice were quarantined for at least 1 week before experimental manipulation. Exponentially growing cells (LNcap, MDA-MB-468) or in vivo passaged tumor fragments (MX-1) were implanted subcutaneously at the right flank of nude mice. When tumors reached an average volume of ~150 mm3, mice were randomized into various treatment groups (6-8 mice/group) in each study. Mice were visually observed daily and tumors were measured twice weekly by calliper to determine tumor volume using the formula [length/2] × [width2]. Group median tumor volume (mm3) was graphed over time to monitor tumor growth. In single agent studies, olaparib (100mg/kg), Talazoparib (BMN 673; MDV3800)  (various doses as indicated), or vehicle (10% DMAc, 6% Solutol and 84% PBS) was administered by oral gavage (p.o.), once daily or Talazoparib (BMN 673; MDV3800)  (0.165 mg/kg) twice daily for 28 consecutive days. Mice were continuously monitored for 10 more days after last day of dosing. In cisplatin combination study, Talazoparib (BMN 673; MDV3800) , olaparib, or vehicle was administered p.o. once daily for 8 days starting on day 1. Cisplatin at a dosage of 6 mg/kg or its vehicle (saline) was administered intra-peritoneally (i.p) as a single injection on day 3, 30 minutes after PARP inhibitor was administered. Combination with carboplatin was conducted in a similar way in MX-1 model in which Talazoparib (BMN 673; MDV3800)  was administered p.o. once daily for either 8 days or 5 days and carboplatin was injected i.p. at single dose of 35 mg/kg, 30 min after Talazoparib (BMN 673; MDV3800)  on day 3.[1]
PAR assay in vivo[1]
MX-1 tumor xenografts were prepared as described in methods. When tumors reached an average volume of ~150 mm3, olaparib (100 mg/kg), Talazoparib (BMN 673; MDV3800)  (1 mg/kg) or vehicle was administered in a single p.o. dosing. Tumors were harvested at 2, 8 and 24 hours after drug dosing, snap frozen in liquid N2. Tumor tissue was then homogenized in PBS on ice and extracted with lysis buffer (25mM Tris pH 8.0, 150mM NaCl, 5mM EDTA, 2mM EGTA, 25mM NaF, 2mM Na3VO4, 1mM Pefabloc, 1% Triton X-100, and protease inhibitor cocktail) containing 1% SDS. Levels of PAR in the tumor lysates were determined by ELISA using PARP in vivo PD Assay II kit.
0.33 and 0.1 mg/kg; Oral gavage and twice daily for 28 consecutive days.

药代性质 (ADME/PK)
Absorption, Distribution and Excretion
After administration of talazoparib 1 mg orally once daily, the mean [% coefficient of variation (CV%)] AUC and maximum observed plasma concentration (Cmax) of talazoparib at steady-state was 208 (37%) ng x hr/mL and 16.4 (32%) ng/mL, respectively. The mean (CV%) steady-state Ctrough was 3.53 (61%) ng/mL. Steady state was reached within two to three weeks of therapy. The Tmax ranges from one to two hours. A high-fat, high-calorie food increased the mean Cmax by 46% and the median Tmax from one to four hours, without affecting the AUC.
The major route of elimination is renal excretion. Approximately 68.7% of the total administered radiolabeled dose of talazoparib was recovered in urine, where 54.6% of that dose was in the form of an unchanged drug. About 19.7% of the drug was recovered in feces, with 13.6% of the dose is unchanged.
The mean apparent volume of distribution of talazoparib is 420 L.
The mean apparent oral clearance is 6.45 L/h. The inter-subject variability is 31%.
Metabolism / Metabolites
Talazoparib undergoes minimal hepatic metabolism. The metabolic pathways include mono-oxidation, dehydrogenation, cysteine conjugation of mono-desfluoro talazoparib, and glucuronide conjugation.
Biological Half-Life
The mean terminal plasma half-life (±standard deviation) is 90 (±58) hours in patients with cancer.
毒性/毒理 (Toxicokinetics/TK)
Hepatotoxicity
Elevations in serum aminotransferase levels are common during talazoparib therapy occurring in 33% of patients, but rising above 5 times the upper limit of the normal range in only 1%. The elevations are generally transient and not associated with symptoms or jaundice. Furthermore, similar rates of aminotransferase elevations were reported in control, comparator arms. Talazoparib has had limited clinical use but has not been linked to instances of acute liver injury with symptoms or jaundice. Because of the limited clinical experience with using talazoparib and other PARP inhibitors, their potential for causing liver injury is not well defined.
Likelihood score: E* (unproved but suspected cause of clinically apparent liver injury).
Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation
No information is available on the clinical use of talazoparib during breastfeeding. Because talazoparib is 74% bound to plasma proteins, the amount in milk is likely to be low. The manufacturer recommends that breastfeeding be discontinued during talazoparib therapy and for one month after the last dose.
◉ Effects in Breastfed Infants
Relevant published information was not found as of the revision date.
◉ Effects on Lactation and Breastmilk
Relevant published information was not found as of the revision date.
Protein Binding
_In vitro_, the protein binding of talazoparib is 74% and is independent of talazoparib concentration.

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。
