In Vitro

Zipalertinib (TAS6417) inhibits EGFR phosphorylation and downstream molecules in NSCLC cell lines expressing EGFR exon 20 insertions, resulting in caspase activation^[1].
? Zipalertinib (TAS6417) is a robust inhibitor against the most common EGFR mutations (exon 19 deletions and L858R) and the most potent against cells harboring EGFR-T790M (1st/2nd generation TKI resistance mutation)^[2].
? Zipalertinib (TAS6417) covalently modified the cysteine residue at position 797 of recombinant EGFR harboring an in-frame insertion mutation in the exon 20 region^[1].
? Zipalertinib (TAS6417) inhibits EGFR signal transduction, leading to cell growth inhibition and apoptosis induction in NSCLC cells driven by EGFR exon 20 insertion mutations^[1].
? Zipalertinib (TAS6417) (0-10 μM) inhibits cell proliferation and EGFR signaling in NSCLC cell lines harboring EGFR common mutations in the presence or absence of T790M^[2].

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

Apoptosis Analysis^[2]

Cell Line:

PC-9, H1975, BID007, BID019, BEAS-2B cells.
Concentration:

0-10 μM.
Incubation Time:

24-48 h.
Result:

Led to apoptosis via inhibition of mutant EGFR.

In Vivo

Zipalertinib (TAS6417) (10-200 mg/kg) causes persistent tumor regression in vivo in EGFR exon 20 insertion-driven tumor models. TAS6417 inhibits mutant EGFR in tumors but not WT EGFR in skin tissues^[1].
? Zipalertinib (TAS6417) had no effect on EGFR-independent proliferation in NCI-H23 or NCI-H460 cells^[1].
? Zipalertinib (TAS6417) administered at 20 mg/kg, which achieves complete suppression of tumor growth, induces a significant decrease in pEGFR, leading to reduction of pAKT and pERK at 1 h. The inhibitory effect is still noted at 6 h, and phosphorylation of EGFR, ATK, and ERK recovered by 24 h^[1].
? Zipalertinib (TAS6417) (100 and 200 mg/kg/day) prolongs survival of animals bearing lung cancer^[1].

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

Animal Model:

Mice implanted with NCI-H1975 EGFR D770_N771insSVD xenografts^[1].
Dosage:

50 and 100 mg/kg.
Administration:

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: ≥ 2.08 mg/mL (5.25 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.08 mg/mL (5.25 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
