Biological Activity
P-glycoprotein[1]
NSC23925 is a novel, selective and effective P-glycoprotein (Pgp) inhibitor. SKOV-3 cells with long-term exposure of 1 μM NSC23925 show stable growth in culture medium. NSC23925 specifically inhibits Pgp overexpression to prevent the emergence of paclitaxel resistance during paclitaxel treatment[1]. NSC23925 reverses chemoresistance in a wide variety of tumor types where Multidrug resistance 1 (MDR1) is highly expressed. Maximal reversal of MDR is typically seen in NSC23925 doses between 0.5 and 1 µM. The IC50 for NSC23925 is 8 µM in SKOV-3/SKOV-3TR and 25 µM in OVCAR8/OVCAR8TR cell lines, whereas the mean concentration of NSC23925 required for maximal reversal of resistance in SKOV-3TR or OVCAR8TR to cytotoxic drugs is 0.5 µM to 1 µM[2].

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: ≥ 1.43 mg/mL (3.39 mM); Clear solution
This protocol yields a clear solution of ≥ 1.43 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (14.3 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: ≥ 1.43 mg/mL (3.39 mM); Clear solution
This protocol yields a clear solution of ≥ 1.43 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (14.3 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
To determine whether NSC23925 can prevent the emergence of paclitaxel resistance, paclitaxel resistant ovarian cancer cells are used. In brief, 1×105 SKOV-3 cells are suspended in culture media containing paclitaxel alone, 1 μM NSC23925 alone, or paclitaxel in combination with 1 μM NSC23925. When the cells are cultured to 90% confluence, 1×105 cells are reseeded in a new tissue culture flask, and the paclitaxel dose is increased stepwise. The initial concentration of paclitaxel is 0.0001 μM. At different selection points cell sublines are collected and stored at liquid nitrogen for further analysis[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Nude female mice at approximately 3 to 4 weeks of age are used. To evaluate the effects of NSC23925 on the induction of paclitaxel resistance in vivo, the paclitaxel resistant cells are established in human ovarian cancer xenograft models. Briefly, on day 1, approximately 2×106 parental sensitive SKOV-3 cells are injected subcutaneously with Matrigel into the flanks of 3 to 4-week-old female nude mice. Administration is initiated 12 days after injection of tumor cells. The mice are randomized into 4 groups and treated intraperitoneally with either saline alone, NSC23925 alone (50 mg/kg), paclitaxel (25 mg/kg) alone, or paclitaxel (25 mg/kg) in combination with NSC23925 (50 mg/kg) twice per week for 3 weeks followed by a treatment-free interval of 2 weeks. The second round of treatment is then continued. The size of tumors is recorded twice a week beginning on day 13. Tumor volume is measured with a digital caliper and calculated according to the formula (length×width2)/2[1].
