In Vitro

Neratinib displays no activity against other serine-threonine kinases such as Akt, cyclin D1/cdk4, cyclin E/cdk2, cyclin B1/cdk1, IKK-2, MK-2, PDK1, c-Raf, and Tpl-2, as well as the tyrosine kinase c-Met^[1].
Neratinib (0.5 ng/mL–5 μg/mL, 2 days) inhibits the proliferation of cell lines that show high levels of HER-2 (3T3/neu, SK-Br-3, and BT474) and is much less active in cell lines that express neither HER-2 nor EGFR (3T3, MDA-MB-435, and SW620) ^[1].
Neratinib (0-2 nM, 12-16 h) arrests BT474 cell cycle at G1-S phase^[1].
Neratinib results in the inhibition of MAPK and Akt phosphorylation, down-regulation of cyclin D1 levels, and induction of p27^[1].

Cell Cycle Analysis^[1]

Cell Line:

BT474
Concentration:

0–2 nM
Incubation Time:

12–16 h

Blocked cell cycle progression, causing a G1-S arrest, a 50% decrease in the number of cells in the S (DNA synthesis) phase of the cell cycle was observed at a concentration of 2 nM.

In Vivo

Neratinib (HKI-272) (0-80 mg/kg/day; i.g.; 42 days) shows anticancer activities against cancer cells that expresses high levels of HER-2 or EGFR^[1].

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

Animal Model:

Female athymic (nude) mice, tumor xenograft^[1]
Dosage:

10, 20, 40, 60 or 80 mg/kg/day
Administration:

Gavage, 42 days
Result:

Reduced tumor growth in a dose-dependent manner in 3T3/neu, BT474, SK-OV-3 and A431 xenografts, but was o inactive in xenografts of MX-1 and MCF-7. Inhibited phosphorylation of HER-2 in BT474 xenografts.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 0.83 mg/mL (1.49 mM); Clear solution

This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
