产品介绍
Lapatinib ditosylate monohydrate (GW572016 ditosylate monohydrate) 是一种ErbB-2EGFR酪氨酸激酶结构域的有效抑制剂,对纯化的EGFRErbB-2IC50值分别为 10.2 和 9.8 nM。
生物活性

Lapatinib ditosylate monohydrate (GW572016 ditosylate monohydrate) is a potent inhibitor of theErbB-2andEGFRtyrosine kinase domains withIC50values against purifiedEGFRandErbB-2of 10.2 and 9.8 nM, respectively[1].

IC50& Target[1]

EGFR

10.8 nM (IC50)

ErbB2

9.2 nM (IC50)

体外研究
(In Vitro)

Lapatinib (GW2016; 0.03-10 μM; 6 hours; BT474 and HN5 cells) treatment inhibits receptor autophosphorylation of EGFR and ErbB-2 in a dose-responsive manner. Phosphorylation of serine 473 of AKT was inhibited by GW2016 in a dose-dependent manner[1].
Lapatinib (GW2016; 72 hours; HN5, A-43, BT474, N87, and CaLu-3 cells) treatment has a selective inhibition of the proliferation of human tumor cell lines[1].
Lapatinib (GW2016; 1-10 μM; 72 hours; HN5 cells) treatment results in induces G1 arrest[1].

Western Blot Analysis[1]

Cell Line:BT474 and HN5 cells
Concentration:0.03 μM, 0.1 μM, 0.3 μM, 1 μM, 3 μM, or 10 μM
Incubation Time:6 hours
Result:Inhibited receptor autophosphorylation of EGFR and ErbB-2 in a dose-responsive manner. Phosphorylation of serine 473 of AKT was also inhibited in a dose-dependent manner.

Cell Proliferation Assay[1]

Cell Line:HN5, A-43, BT474, N87, and CaLu-3 cells
Concentration:
Incubation Time:72 hours
Result:Inhibited the growth of tumor cells overexpressing EGFR or ErbB-2.

Cell Cycle Analysis[1]

Cell Line:HN5 cells
Concentration:1 μM, or 10 μM
Incubation Time:72 hours
Result:Resulted in induction of G1 arrest.
体内研究
(In Vivo)

Lapatinib (GW2016; 30-100 mg/kg; oral administration; twice daily; for 21 days; CD-1 nude female mice) treatment inhibits tumor xenograft growth of the HN5 cells in a dose-responsive manner at 30 and 100 mg/kg, with complete inhibition of tumor growth at the higher dose[1].

Animal Model:CD-1 nude female mice (4-6 weeks old) with HN5 cells[1]
Dosage:30 mg/kg, 100 mg/kg
Administration:Oral administration; twice daily; for 21 days
Result:Inhibited tumor xenograft growth of the HN5 cells in a dose-responsive manner.

    请依序添加每种溶剂: 10% DMSO    90% (20%SBE-β-CDin saline)

    Solubility: 2.5 mg/mL (2.65 mM); Suspended solution; Need ultrasonic

    此方案可获得 2.5 mg/mL (2.65 mM) 的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL20% 的 SBE-β-CD 生理盐水水溶液中,混合均匀。

    将 2 g 磺丁基醚 β-环糊精加入 5 mL 生理盐水中,再用生理盐水定容至 10 mL,完全溶解,澄清透明
