Description

Zotizalkib (TPX-0131) is a potent, selective, CNS-penetrant and orally active inhibitor of wild-type ALK (IC50 of 1.4 nM) and ALK-resistant mutation, e.g. G1202R (IC50 of 0.3 nM), L1196M (IC50 of 0.3 nM). Zotizalkib has strong antitumor activities[1].

IC50 & Target

IC50: 1.4 nM (Wild-typr AKT); 0.2-6.6 nM (mutant ALK variants)[1]

In Vitro

Zotizalkib potently inhibits wild-type ALK (IC50=1.4 nM) and 26 ALK resistance mutations. Zotizalkib inhibits C1156Y, E1210K/S1206C, L1198F/C1156Y, L1196M/L1198F, E1210K, L1196M, T1151M, deleted G1202, S1206R, G1202R/L1198F, F1174L, F1245C, R1275Q, and G1202R ALK mutations with IC50 values of <1 nM. Zotizalkib has IC50 values of 1-2 nM for the following ALK mutations: L1198F, L1152R, F1174S, T1151-L1152 insT, V1180L, G1269A, F1174C. Zotizalkib is less active against ALK mutations including I1171N, L1152P, D1203N, D1203N/E1210K, and G1269S, with IC50 values of 2-7 nM[1].
Zotizalkib is a potent inhibitor of ALK autophosphorylation in Ba/F3 cells expressing EML4-ALK G1202R solvent front, EML4-ALK G1202R/L1196M, or EML4-ALK G1202R/L1198F mutations, with IC50 values of approximately 3-10 nM[1].

In Vivo

Zotizalkib (2-10 mg/kg; p.o.; twice a day; for 2 weeks) treatment at 2 mg/kg, 5 mg/kg, and 10 mg/kg resulted in dose-dependent tumor growth inhibition (TGI) of 64%, 120%, and 200% (complete regression), respectively[1].

Dosage: 2 mg/kg, 5 mg/kg, and 10 mg/kg
Administration: p.o.; twice a day; for 2 weeks
Result: Caused complete tumor regression in ALK mutation-dependent xenograft models.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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 (4.65 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.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.08 mg/mL (4.65 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

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.
