In Vitro

Navitoclax (ABT-263) is active against approximately one-half of the cell lines of the PPTP in vitro panel. The median IC₅₀ for all of the lines in the panel is 1.91 μM^[1]. Navitoclax in combination with chemotherapy agents leads most ovarian cancer cell lines a synergistic response, and enhances the caspase activation in both SK-OV-3 and IGROV-1 cell lines^[2].

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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% Ethanol 60% Phosal 50 PG 30% PEG400
Solubility: 7.5 mg/mL (7.70 mM); Clear solution; Need ultrasonic
Protocol 2

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.08 mg/mL (2.13 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 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 3

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.08 mg/mL (2.13 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.
Protocol 4

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.08 mg/mL (2.13 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.
