PARP2 0.87 nM (Ki) PARP1 1.2 nM (Ki)
体外研究(In Vitro)
Talazoparib shows an EC50 of 2.51 nM in cellular PARylation assay.
Talazoparib shows EC50s of 0.3 nM, 5 nM and 0.31 for MX-1 cells (BRCA1 mutant), Capan-1 cells (BRCA2 mutant) and MRC-5 cells (normal).
has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
Talazoparib (0.33 mg/kg; i.g.; once daily; for 28 days) exhibits antitumor activity against BRCA1 mutant breast cancer model in mice.
Talazoparib exhibits moderate oral bioavailability (rat 56%) and C max (rat 7948 ng/mL) following oral administration (rat 10 mg/kg). Talazoparib exhibits the terminal elimination half-life (rat 2.25 h) due to plasma clearance (2 mL/min/kg) following intravenous administration (rat 5 mg/kg). has not independently confirmed the accuracy of these methods.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
