Biological Activity
Kd: 5.1 nM (P-gp)[1]
Tariquidar methanesulfonate, hydrate (XR9576 methanesulfonate, hydrate) is a potent modulator of P-gp mediated [3H]-Vinblastine and [3H]-Paclitaxel transport as it increases the steady-state accumulation of these cytotoxics in CHrB30 cells to levels observed in non-P-gp-expressing AuxB1 cells (EC50=487±50 nM). [3H]-Tariquidar binds to CHrB30 membranes with the highest affinity (Kd=5.1±0.9 nM, n=7) and a binding capacity (Bmax) of 275±15 pmol/mg membrane protein. In contrast to the parental cell line, the accumulation of [3H]-Vinblastine is increased in a dose-dependent fashion by the modulators XR9576 (EC50=487±50 nM). The MDR modulator Tariquidar is able to inhibit 60-70% of the vanadate-sensitive ATPase activity, with potent IC50 value of 43±9 nM[1]. Tariquidar (XR9576) potentiates the cytotoxicity of several drugs including Doxorubicin, Paclitaxel, Etoposide, and Vincristine; complete reversal of resistance is achieved in the presence of 25-80 nM Tariquidar. Tariquidar is a potent inhibitor of photoaffinity labeling of P-gp by [3H]Azidopine implying a direct interaction with the protein[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: ≥ 5 mg/mL (5.60 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.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Protocol
Cells (EMT6 AR1.0 8×102/well; A2780 5×103/well; 2780AD 6×103/well) are seeded into 96-well plates. After ~4 h, varying concentrations of Tariquidar are added, and cells are incubated for an additional 4 days (EMT6 AR1.0) or 6 days (2780AD) before quantification of cell growth and calculation of IC10 values (concentration resulting in 10% inhibition of cell growth)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice[2]
MC26 tumor slurry is implanted s.c. in BALB/c mice (day 0). The animals are then randomized, 24 h later, into groups of 15-18 and treated once with various regimens. Tariquidar methanesulfonate or vehicle is administered either i.v. via a lateral tail vein or p.o. with Doxorubicin (5 mg/kg) or vehicle i.v. The modulator is administered either i.v. at 2-4 mg/kg (10 mL/kg) at the same time as Doxorubicin or p.o. at 2-8 mg/kg (10 mL/kg) 1 h before the Cytotoxic drug. GG918 is administered p.o. 1 h before doxorubicin. All of the animals are weighed twice weekly. The animals are killed by cervical dislocation on day 14, and the tumors are excised and weighed. The data are analyzed by Student’s t test.
Rat[2]
Male CD rats (3 animals per time point) are dosed i.v. with paclitaxel alone [15 min infusion at 10 mg/kg in Tween 80:ethanol:5% dextrose (5:10:85% v/v/v)] or in combination with Tariquidar methanesulfonate (10 mg/kg). Tariquidar methanesulfonate is administered as a bolus (i.v.) dose 15 min before infusion of Paclitaxel. Blood samples are collected by cardiac puncture using heparinized syringes at various times between 0.083 and 48 h and are centrifuged to prepare plasma, which is stored at −20°C until analysis. Paclitaxel concentration in plasma samples is measured by a LC-MS/MS assay.
