生物活性

Pyrotinib dimaleate (SHR-1258 dimaleate) is a potent and selective EGFR/HER2 dual inhibitor with IC50s of 13 and 38 nM, respectively[1].

IC50 & Target[1]

HER2

38 nM (IC50)

EGFR

13 nM (IC50)

体外研究
(In Vitro)

Pyrotinib dimaleate has high potency in HER2-dependent cell lines (BT474, SK-OV-3), while showing much weaker inhibition in the HER2 negative cell line (MDA-MB-231). Pyrotinib dimaleate inhibits BT474 and SK-OV-3 cells with IC50s of 5.1 and 43 nM, respectively. Pyrotinib dimaleate displays high selectivity as HKI-272 when tested in a panel of different kinases such as KDR, c-Kit, PDGFRβ, c-Src and C-Met (c-Src with an IC50 of 790 nM, and others >3000 nM)[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Pyrotinib dimaleate has acceptable bioavailability of 20.6%, 43.5% and 13.5% in nude mice, rats and dogs, respectively. Pyrotinib dimaleate has favorable drug-like physicochemical properties and shows relatively higher oral exposure in human subjects (oral; t1/2=15 h) with a much longer half life than that of preclinical animal species such as mouse (i.v.; t1/2=1.56 h; i.g.; t1/2=2.52 h) and rat (i.v.; t1/2=4.42 h; i.g.; t1/2=3.38 h)[1].

动物实验:

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2.5 mg/mL (3.07 mM); 悬浊液; 超声助溶

    此方案可获得 2.5 mg/mL的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (3.07 mM); 悬浊液; 超声助溶

    此方案可获得 2.5 mg/mL的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

    20% SBE-β-CD in Saline 的配制(4°C,储存一周):2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。

Cell Assay
[1]

Cancer cells (A431, SK-BR-3 and NCI-N87) are treated at a suitable concentration of Pyrotinib for 72 hours. Cell proliferation is determined by a sulforhodamine B (SRB) method. The IC50 values are calculated by the data of inhibition rates of serial concentrations of Pyrotinib dimaleate[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[1]

Rats[1]
Sprague Dawley (SD) rats (200-250g, 3 males and 3 females) are used .Test compounds (include Pyrotinib dimaleate) are administrated in both intravenous ( i.v. ; 3 mg/kg) and intragastric ( i.g. ;3 mg/kg) for rats to obtain their bioavailability. Plasma samples of nude mice is collected at pre-dose and 0.083, 0.25, 0.5, 1, 2, 4, 6, 8, 12, 24 h after the IV administration [1].
Mice[1]:
In vivo efficacy studies are performed on BALB/Ca-nude mice (6 to 7 weeks, female) from SLAC. Nude mice are hypodermic inoculated BT-474 human breast cancer cell or SK-OV-3 ovarian cancer cell. After tumor grows to 150-250 mm3, mice are randomly divided into groups and dosed with Pyrotinib (2.5, 5, 10, 20 mg/kg) once daily. The volume of tumors and the weight of the mice are measured and recorded for 2-3 times per weeks[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
