代谢
Talazoparib 通过单一氧化、脱氢、半胱氨酸与单一去氟代谢物的结合以及葡萄糖醛酸结合进行代谢。代谢对 Talazoparib 清除的整体贡献是微小的。
Talazoparib is metabolized via mono-oxidation, dehydrogenation, cysteine conjugation of a mono-desfluoro metabolite, and glucuronide conjugation. The overall contribution of metabolism to talazoparib elimination is minimal.

毒理性
  • 毒性总结
Talazoparib 由于其药理机制具有致裂变性。Talazoparib 似乎不具有致突变性,并且没有关于其致癌性的数据。在长达3个月的重复剂量毒性研究中,大鼠的剂量≥0.04 mg/kg/天和犬的剂量≥0.01 mg/kg/天导致了器官重量减轻、腔内细胞碎片、精子减少以及睾丸和附睾的退化和萎缩。这些剂量相当于大约是正常人体暴露的1.0倍和0.2倍。在大鼠中,当剂量≥1 mg/kg/天,相当于正常人体暴露的9.5倍时,观察到卵巢滤泡闭锁。虽然不存在生育数据,但这些结果提示由于Talazoparib暴露可能会降低生育能力。
Talazoparib is clastogenic due to its pharmacological mechanism. Talazoparib does not appear to be mutagenic and no data is available on carcinogenicity. In repeat-dose toxicity studies up to 3-months duration at doses ≥0.04 mg/kg/day in rats and ≥0.01 mg/kg/day in dogs resulted in decreased organ weights, luminal cellular debris, reduced sperm, and degeneration/atrophy in the testis and epididymis. These doses were equivalent to approximately 1.0 times and 0.2 times normal human exposure. Follicular atresia of the ovary was observed in rats at doses ≥1 mg/kg/day, equivalent to 9.5 times normal human exposure. While no fertility data exists these results suggest a potential for reduced fertility due to talazoparib exposure.

毒理性
  • 肝毒性
血清氨基转移酶水平升高在塔拉佐帕利治疗期间很常见,发生在33%的患者中,但仅有1%的患者会升高到正常上限的5倍以上。这些升高通常是暂时的,不伴随症状或黄疸。此外,对照组和比较组中报告的氨基转移酶升高率相似。塔拉佐帕利在临床上的使用有限,但并未与出现急性肝损伤症状或黄疸的实例相关联。由于使用塔拉佐帕利和其他PARP抑制剂的临床经验有限,它们导致肝损伤的潜力尚未得到很好的定义。
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.

制备方法与用途

生物活性

Talazoparib (BMN 673) 是一种新型PARP抑制剂,在无细胞试验中对PARP1的IC50为0.58 nM,并有效抑制PARP-2,但不抑制PARG,对PTEN突变型高度敏感。Phase 3研究显示其有效性。

体外研究

BMN-673 选择性与PARP结合,且通过碱基切除修复途径抑制单链DNA断裂的修复。它增强了DNA链断裂的积累,促进基因组不稳定性,并最终导致细胞凋亡。BMN 673特别针对携带BRCA-1或BRCA-2突变的癌细胞具有单药细胞毒性作用:对于BRCA-1突变(MX-1, IC50 = 0.3 nM)和BRCA-2突变(Capan-1, IC50 = 5 nM)的细胞。相反,它对MRC-5正常人类成纤维细胞及其他含野生型BRCA-1 和 BRCA-2基因的肿瘤细胞系表现出较低的毒性(IC50为90 nM到1.9 μM)。此外,BMN 673作用于培养的人类癌细胞时,显著增强了Temozolomide 和 SN-38的细胞毒性效果。

体内研究

在大鼠的药代动力学研究中,BMN673每天单独给药具有>50%口服生物有效性和良好的药代动力学特性。在MX-1移植瘤肿瘤模型的研究中,BMN 673每天口服给药显著增强了细胞毒性疗法的抗肿瘤效果,并且这种作用表现出剂量依赖性。

特征

Talazoparib (BMN 673, LT-673) 是目前已报道的最有效的选择性PARP抑制剂。
