In vitro
In vitro In RT-112 cells, HUVECs, KATO-III cells, and SNU-16 cells, LY2874455 inhibits FGF/FGFR-mediated signaling activities. LY2874455 shows FGFR-dependent antiproliferative effects in KMS-11, OPM-2, SNU-16 and KATO-III cells. [1]
Kinase Assay Biochemical filter-binding assays for detection of FGFR phosphorylation activities
Reaction mixtures contains 8 mM Tris-HCl (pH 7.5), 10 mmol/L HEPES, 5 mM dithiothreitol, 10 μM ATP, 0.5 μCi 33P-ATP, 10 mM MnCl2, 150 mM NaCl, 0.01% Triton X-100, 4% dimethyl sulfoxide, 0.05 mg/mL poly(Glu:Tyr) (4:1, average molecular weight of 20–50 kDa), and 7.5, 7.5, and 16 ng of FGFR1, FGFR3, and FGFR4, respectively, and are incubated at room temperature for 30 minutes followed by termination with 10% H3PO4. The reaction mixtures are transferred to 96-well MAFB filter plates that are washed 3 times with 0.5% H3PO4. After air-drying, the plates are read with a Trilux reader.

Concentrations ~1 μM
Incubation Time 72 hours
Method

Cells (2,000 per well) are first grown in RPMI for 6 hours and treated with LY2874455 at 37 ℃ for 3 days. The cells are stained at 37℃ for 4 hours and then solubilized at 37℃ for 1 hour. Finally, the plate is read at 570 nm using a plate reader (Spectra Max Gemini XS).

In Vivo
In vivo LY2874455 exhibits a potent inhibition of FGF-induced Erk phosphorylation in the heart tissues of mice with TED50 and TED90 values of 1.3 and 3.2 mg/kg, respectively. In mice bearing RT-112, OPM-2 (DSMZ), SNU-16, or NCI-H460 xenograft, LY2874455 (3 mg/kg p.o.) results in dose-dependent inhibition of the tumor growth. [1]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 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.
