PF-3758309 dihydrochloride is less active against the other two group A PAKs (PAK2, IC50=190 nM; PAK3, IC50=99 nM) but exhibits similar enzymatic potency against the kinase domains of the other group B PAKs (PAK5, Ki=18.1 nM; PAK6, Ki=17.1 nM) and group A PAK1 (Ki=13.7 nM)[1]. PF-3758309 dihydrochloride is known to suppress anchorage-independent growth of a panel of tumor cell lines (IC50=4.7 nM) as well as phosphorylation of the PAK4 substrate GEF-H1 (IC50=1.3 nM) in cells[1]. Additionally, in HCT116 cells, PF-3758309 dihydrochloride prevents endogenous pGEF-H1 accumulation. PF-3758309 effectively suppresses A549 cell growth that is anchorage-independent (IC50=27 nM) and proliferation (IC50=20 nM)[1].

| ln Vivo |
In HCT116 and A549 models, PF-3758309 dihydrochloride (7.5-30 mg/kg; po; twice daily for 9–18 days) causes a statistically significant tumor growth inhibition (TGI)[1].
|
| Animal Protocol |
Animal/Disease Models: Female nu/nu, CRL breed 6–8 weeks old mice (bearing HCT116 and A549 tumors)[1]
Doses: 7.5-30 mg/kg Route of Administration: Oral administration; twice (two times) daily for 9-18 days Experimental Results: Significant tumor growth inhibition (TGI) in HCT116 and A549 models. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
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.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 1.7745 mL | 8.8723 mL | 17.7447 mL | |
| 5 mM | 0.3549 mL | 1.7745 mL | 3.5489 mL | |
| 10 mM | 0.1774 mL | 0.8872 mL | 1.7745 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
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.
