A-385358 is a selective inhibitor of Bcl-XL with Kis of 0.80 and 67 nM for Bcl-XL and Bcl-2, respectively, in fluorescence polarization assays. Treatment of IL-3-deprived FL5.12/Bcl-XL cells for 24 hours with A-385358 results in cell killing with an EC50 of 0.47±0.05 μM (n=68). This effect is accompanied by an increase in caspase-3 activity. Consistent with the greater affinity for the Bcl-XL versus Bcl-2 hydrophobic grooves, the EC50 of A-385358 for IL-3-depleted FL5.12/Bcl-2 cells (1.9±0.1 μM; n=55) is 4-fold higher relative to the cytokine-deprived FL5.12/Bcl-XL cells. In addition, A-385358 is more effective at stimulating cytochrome c release from mitochondria isolated from FL5.12/Bcl-XL versus Bcl-2 cells[1].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (3.91 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 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 (25.0 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.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (3.91 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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
FL5.12 cells suspended in EMB growth medium containing 4% fetal bovine serum (FBS) are incubated at 37°C for 1 hour in 10 μM A-385358. Compound concentration is determined by high-performance liquid chromatography before and after the 1-hour incubation following brief centrifugation. To analyze membrane-bound fractions following compound incubation, cells are washed once with 10 volumes of cold PBS and lysed with 4 mL of water. A-385358 concentration is determined from aliquots of lysate before and after centrifugation[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
A549 cells (1×105) are plated in 96-well plates in medium containing 10% fetal bovine serum. Following attachment, A-385358 is added to one set of wells (final concentration of 50 μM in 10% FBS) and medium is added to another set. [3H]Paclitaxel (5 μM; 0.5 μCi/mL final concentration) is added to all wells and the cells are incubated at 37°C for various periods of time. For washout experiments, cells are exposed first to [3H]paclitaxel for 2 hours. The cells are washed once with medium and then incubated with fresh medium with or without 50 μM A-385358 at 37°C for various periods of time[1].

For efficacy studies, male CD-1 nude mice are inoculated with a 1:5 dilution of tumor brei in 50% Matrigel and analysis is conducted. A-385358 is delivered in a vehicle containing 5% Tween 80, 20% propylene glycol, and 75% PBS (pH 3.8). Paclitaxel is formulated according to the recommendations of the manufacturer. For combination therapy of paclitaxel plus A-385358, both drugs are administered i.p. with the paclitaxel given several hours before treatment with A-385358 (except for immunohistochemistry studies looking at expression of MPM-2 and caspase-3 wherein the two drugs are given simultaneously)[1].
