On Ba/F3 cells, pexidartinib exhibits more activity than CSF1R-IN-15 (0.007-10 μM, 72 h) [1]. Equilibrium dialysis was used to evaluate the plasma protein binding of CSF1R-IN-15. Following a 6-hour incubation period at 37°C and a 5 μM concentration, CSF1R-IN-15 bound to mouse plasma proteins at a rate of 69%[1].

The in vivo pharmacokinetic characteristics of CSF1R-IN-15 were obtained using cassette dosing trials. In C57BLKS mice, the CSF1R-IN-15 t1/2, C0, AUC0-∞, CLobs, and Vss,obs were 0.5 h, 37 ng/ml, 18 h*ng/ml, 54 L/h/kg, and 32 L/k[1].

Cell Viability Assay[1]
Cell Types: Ba/F3-hCSF1R Cells Tested Concentrations: 0.007-10 μM Incubation Duration: 72 h Experimental Results: demonstrated no activity while pexidartinib has superior activity. |
| Animal Protocol |
Animal/Disease Models: In Vivo pharmacokinetic/PK Study
Doses: 1mg/kg Route of Administration: intravenous (iv) injection single dosing of drugs (1 mg/kg each) in a 20% DMSO, 80% PEG400 formulation. Blood sampling was done after 10, 30, 60, 120, 240, and 480 min. Experimental Results: In vivo pharmacokinetic/PK indexes were t1/2 (0.5 h), C0 (37 ng/mL), AUC0-∞ (18 h*ng/mL), CLobs (54 L/ h/kg), and Vss,obs (32 L/kg), respectively. |

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
