In Vitro

Tinodasertib (ETC-206) inhibits eIF4E phosphorylation in HeLa cell line with an IC₅₀ of 321 nM. The anti-proliferative effects of ETC-206 are assessed in vitro, using CellTiter-Glo viability assay against 25 hematological cancer cell lines including the K562 cell line that overexpresses eIF4E (K562 o/e eIF4E). The IC₅₀s are 1.71 μM, 3.36 μM, 3.70 μM, 4.81 μM, 5.13 μM, 5.05 μM, 6.70 μM, 9.76 μM, and 48.8 μM for SU-DHL-6, GK-5, MC 116, P3HR-1, DOHH2, MPC-11, Ramos.2G6.4C10, AHH-1, and K562 o/e eIF4E cells, respectively^[1].

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

In Vivo

The antitumor effect of ETC-206 is then assessed in a K562 e/o eIF4E mouse xenograft model after oral administration at 25, 50, or 100 mg/kg alone or in combination with a 2.5 mg/kg fixed dose of Dasatinib throughout the study. Dasatinib at 2.5 mg/kg elicits a tumor growth inhibition (TGI) of 88% with one tumor-free animal. In contrast, ETC-206 alone only yields a maximum TGI of 23% at the highest administered dose of 100 mg/kg, which does not impede tumor growth, and is similar to the nontreated animals. ETC-206 with 2.5 mg/kg of Dasatinib not only increases tumor growth inhibition in a dose-dependent manner but, more importantly leads to 2, 5, and 8 out of 8 tumor-free animals at 25, 50, and 100 mg/kg, respectively. The combination of ETC-206 and Dasatinib inhibits tumor growth at all tested doses, and no weight loss is recorded. Both the combination of ETC-206 and Dasatinib and, on the other hand, the dual MNK1/2 and BCR-ABL1 inhibitors prevent tumor growth in the same mouse xenograft model. ETC-206 has moderate terminal elimination half-life (t_1/2=1.7 h, and 1.77 h for mouse (1 mg/kg, i.v.), mouse (5 mg/kg, p.o.))^[1].

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: ≥ 5 mg/mL (12.24 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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% (20% SBE-β-CD in Saline)

Solubility: ≥ 5 mg/mL (12.24 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

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

Solubility: ≥ 5 mg/mL (12.24 mM); Clear solution

This protocol yields a clear solution of ≥ 5 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 (50.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Animal Administration^[1]

Mice^[1]
CD-1 female mice (6-8 weeks old) are weighed, and those selected for dosing are 24±2 g. Three mice are randomly grouped per time point. Mice are administered a single dose of 1 mg/kg of ETC-206 via tail vein injection or a single dose of 5 mg/kg of ETC-206 via oral gavage. The volume of injection for intravenous (i.v.) and oral (p.o.) administration is 4 mL/kg and 8 mL/kg, respectively^[1].

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.
