In vivo batch selection In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	3.5mg/ml (5.51mM)	Taking the 1 mL working solution as an example, add 50 μL of 70 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	3.5mg/ml (5.51mM)	Taking the 1 mL working solution as an example, add 50 μL of 70 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	FGFR1 (Cell-free assay) 3.09 nM FGFR2 (Cell-free assay) 4.3 nM FGFR3 (Cell-free assay) 27 nM FGFR4 (Cell-free assay) 45.3 nM
In vitro	In FGFR1-4 Ba/F3 cells, FIIN-2 inhibits cell proliferation with EC50 in the single- to double-digit nanomolar range. This compound also shows excellent antiproliferative activity in a variety of backgrounds, including cell lines that have gatekeeper mutations in FGFR1 and that are dependent on FGFR4.
Kinase Assay	Biochemical assays
Kinase Assay	Biochemical assays are performed by a broad-coverage, TR-FRET-based kinase binding assay platform.
In vivo	In a zebrafish developmental model, FIIN-2 causes mild or severe phenotypes to the tail morphogenesis by inhibiting FGFR.
