In Vitro

TAI-1 disrupts Hec1-Nek2 protein interaction, leads to Nek2 degradation, induces significant chromosomal misalignment in metaphase, and induces apoptotic cell death^[1].
TAI-1 induces cancer cell death through the induction of cleavage of apoptotic proteins Caspase 3 and PARP and degradation of anti-apoptotic proteins MCL-1 and suggests that TAI-1 leads to activation of the apoptotic pathways^[1].
TAI-1 is effective in many cancer cells, such as Chronic myeloid leukemia, Cervical cancer, Breast, metastatic-pleural, invasive ductal carcinoma, Acute myeloid leukemia, Myelogenous leukemia, Colorectal carcinoma cells, with GI₅₀ less than 100 nM^[1].

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

In Vivo

TAI-1 (20 mg/kg intravenously IV/ or 150 mg/kg per oral PO/BID) inhibits tumor growth in multiple cancer xenograft models^[1].

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

Animal Model:

C.B-17 SCID mice (6-7 weeks, 21-24 g)^[1].
Dosage:

20 mg/kg intravenously IV/ or 150 mg/kg per oral PO/BID.
Administration:

QDx28 cycles.
Result:

Led to significant tumor growth retardation in Huh-7 and modest tumor inhibition was noted tor the Colo205 and MDA-MB-231 models.

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 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (5.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 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 (25.0 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.
