Biological Activity
| Targets | FGFR4 6.5 nM (IC50) FGFR2 505 nM (IC50) |
| ln Vivo | FGFR4-IN-5 (oral gavage; 10 mg/kg; single dose) reveals a high Cmax, low clearance, the Cmax values are 423 ng/ml, 588 ng/ml, and 2820 ng/ml in mice, rat and cynamolgus monkey, respectively. And the oral bioavailability are 20, 12, and 27% in mouse, rat, and cyno, respectively[1]. FGFR4-IN-5 (oral gavage; 100 mg/kg; twice daily; 28 days) exhibits strong antitumor activity in an orthotopic Hep3B HTX model[1]. FGFR4-IN-5 (oral gavage; 10, 30, and 100 mg/kg; twice daily; 11 days) results in dose-dependent growth inhibition of resistant tumors. Tumor Regression is observed at 30 and 100 mg/kg, with %ΔT/ΔC of 67% and 70%, respectively. However, treatment with sorafenib at 100 mg/kg once daily does not provide any benefit in vivo[1]. |
| Animal Protocol |
Animal/Disease Models: Hep3B cell bearing mice model[1] Doses: 100 mg/kg Route of Administration: Oral gavage; 100 mg/kg; twice (two times) daily; 28 days Experimental Results: Resulted in tumor regression and sustained growth inhibition. Animal/Disease Models: Sorafenib-resistant tumors established to mice bearing Huh7 tumors[1] Doses: 10, 30, and 100 mg/kg Route of Administration: Oral gavage; 10, 30, and 100 mg/kg; twice (two times) daily; 11 days Experimental Results: Resulted in dose-dependent growth inhibition of resistant tumors. |

Solubility Data
| Solubility (In Vitro) | DMSO: 100 mg/mL (192.17 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.80 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (4.80 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
