Biological Activity
In vitro, PLX647 potently inhibits proliferation of BCR-FMS cells, with an IC50 of 92 nM. A corresponding Ba/F3 cell line expressing BCR-KIT is also quite sensitive to PLX647, with an IC50 of 180 nM. PLX647 also inhibits endogenous FMS and KIT, as demonstrated by inhibition of the ligand-dependent cell lines M-NFS-60 (IC50=380 nM) and M-07e (IC50=230 nM), which express FMS and KIT, respectively[1].
PLX647 potently inhibits the growth of FLT3–ITD-expressing MV4-11 cells (IC50=110 nM). PLX647 displayed minimal inhibition of the proliferation of Ba/F3 cells expressing BCR–KDR (IC50=5 μM). PLX647 inhibits osteoclast differentiation with an IC50 of 0.17 μM[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
PLX647 (40 mg/kg; p.o.; male Swiss Webster mice) reduces LPS-induced TNF-α and IL-6 release[1].
PLX647 (20-80 mg/kg; p.o.; daily or twice daily from 27-41 days) shows effects on collagen-induced arthritis[1].
PLX647 (30 mg/kg) results in significant inhibition of TRAP5b immunostaining and bone osteolysis. PLX647 (30 mg/kg BID) is able to prevent bone damage by the tumor cells[1].

Animal Model:Male C57BL/6 mice (mouse unilateral ureter obstruction model)[1]
-
Dosage:40 mg/kg
-
Administration:P.o.; twice daily for 7 days
-
Result:Resulted in reduction in the levels of F4/80+ macrophages by 77%.
-
Animal Model:7-9 wk old Male DBA/1J mice (Mouse collagen-induced arthritis model)[1]
-
Dosage:20 mg/kg, 80 mg/kg
-
Administration:P.o.; daily (20 mg/kg) from 27-41 days, twice daily (80 mg/kg) from 27-41 days
-
Result:20 mg/kg PLX647 had no initial effect on the development of severe arthritis. However, starting on day 33, no further development of disease severity was recorded, and a 30% inhibition of the macroscopic signs of arthritis was evident in clinical score on day 41. Mice treated with 80 mg/kg BID PLX647 initially shows delayed development of severe arthritic signs. Starting on day 33, the signs of arthritis began to decrease in this treatment group, reaching a maximum reversal of 76% on day 41.

Solvent & Solubility
DMSO : 25 mg/mL (65.38 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.54 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 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.
Please enter the basic information of animal experiments:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
