For GM7373 cells treated with FGF2 (30 ng/mL) and PBS (10%), respectively, KIN59 (0-100 µM; 24 h) suppresses cell growth with IC50 values of 5.8 and 63 µM [1]. In FGFR1-overexpressing GM7373-FGFR1 cells stimulated by FGF2 (10 ng/mL), KIN59 (60 µM; 30 min) suppresses the production of P-Akt and p-FGFR1 [1]. KIN59 has IC50 values of 44 μM and 67 μM, respectively, which indicate its ability to inhibit human thymidine phosphorylase (TPase) and recombinant bacteria (E. coli) [2].

ln Vivo |
In mice, anticancer activity is demonstrated by KIN59 (15 mg/kg; subcutaneous injection; twice daily beginning on day 2 for 20 days) [1].

Cell Assay |
Cell Proliferation Assay[1]
Cell Types: GM7373 cells Tested Concentrations: 0-100 µM Incubation Duration: 24 h Experimental Results: Inhibited FGF2 (30 ng /mL)-induced proliferation of bovine macrovascular endothelial GM7373 cells in a dose-dependent manner with IC50 values of 5.8, 63 µM for FGF2 and PBS, respectively. Western Blot Analysis[1] Cell Types: GM7373-FGFR1, GM7373-VEGFR2 cells Tested Concentrations: 60 µM Incubation Duration: 30 min Experimental Results: Inhibited FGFR1 phosphorylation and Akt activation triggered by FGF2 in FGFR1-overexpressing GM7373-FGFR1 cells, demonstrated minor inhibitors on VEGF-mediated VEGFR2 phosphorylation and Akt activation in GM7373 cells overexpressing VEGFR2. |
Animal Protocol |
Animal/Disease Models: Eightweeks old female, 25 g, athymic, nude nu/nu (nude) mice (F2T-luc2.9 cells)[1]
Doses: 15 mg/kg Route of Administration: Sc; twice (two times) daily from day 2 (one time/day during the weekend) at a site distant from the tumor (inoculation) site for 20 days Experimental Results: Caused a significant inhibition in the rate of tumor growth. |

Solubility (In Vivo) |
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).

10 mM | 0.1959 mL | 0.9794 mL | 1.9587 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.
