Targets

FLT3 ^[1]	Syk ^[1] (Cell-free assay)
	41 nM

In Vitro
In vitro	R406 is an ATP-competitive inhibitor of Syk with a Ki value of 30 nM. R406 selectively inhibits Syk-dependent signaling with EC50 values ranging from 33 nM to 171 nM, more potently than Syk-independent pathways in different cells. ^[1] R406 inhibits cellular proliferation of a large panel of diffuse large B-cell lymphoma (DLBCL) cell lines at EC50 values ranging from 0.8 μM to 8.1 μM. R406 treatment (1 μM or 4 μM) induces the activation of caspases 9 and 3, but not caspase 8, leading to significant apoptosis of the majority of DLBCL cell lines. Pretreatment of R406 completely blocks the phosphorylation of SYK525/526 and the SYK-dependent phosphorylation of BLNK in R406-sensitive DLBCLs following B-cell receptor (BCR) crosslinking. ^[2] R406 potently decreases MMP-9 mRNA levels by 2.8- and 4.3-fold lower than controls after 24 and 48 hours treatment, respectively, and reduces the invasive capacity of the RL cells. ^[3]
Kinase Assay	In-vitro Fluorescence Polarization Kinase Assays
Kinase Assay	R406 is serially diluted in DMSO and then diluted to 1% DMSO in kinase buffer (20 mM HEPES, pH 7.4, 5 mM MgCl₂, 2 mM MnCl₂, 1 mM DTT, 0.1 mg/mL acetylated BGG). ATP and substrate in kinase buffer are added at room temperature, resulting in a final DMSO concentration on 0.2%. The kinase reactions are performed in a final volume of 20 μL containing 5 μM HS1 peptide substrate and 4 μM ATP and started by addition of 0.125 ng of Syk in kinase buffer. The reaction is allowed to proceed for 40 minutes at room temperature. The reaction is stopped by the addition of 20 μL of PTK quench mix containing EDTA/anti-phosphotyrosine antibody (1X final)/fluorescent phosphopeptide tracer (0.5X final) diluted in FP Dilution Buffer. The plate is incubated for 30 minutes in the dark at room temperature and then read on a Polarion fluorescence polarization plate reader. Data are converted to amount of phosphopeptide present using a calibration curve generated by competition with the phosphopeptide competitor provided in the Tyrosine Kinase Assay Kit. For IC50 determination, R406 is tested at eleven concentrations in duplicate and curve-fitting is performed by non-linear regression analysis using Prism GraphPad Software.

	濃度	Dissolved in DMSO at a concentration of 10 mM, final concentrations ~ 5 μM
	反応時間	72 or 96 hours
	実験の流れ	DLBCL cell lines are treated with serial dilutions of R406 (0.3, 0.6, 1.25, 2.5, or 5 μM) for 72 or 96 hours. Thereafter, cellular proliferation is determined by MTT assay, and cell apoptosis is assessed by using annexin V–FITC/propidium iodide (PI) staining. For the determination of caspase 9, 8, and 3, cells are lysed, size-fractionated by polyacrylamide gel electrophoresis (PAGE), and immunoblotted.

In Vivo
In Vivo	R406 has shown efficacy in a number of animal models of immune disorders. Oral administration of R406 in mice with immune complex-mediated inflammation significantly inhibits the cutaneous reverse passive Arthus reaction by approximately 72% and 86% at 1 mg/kg and 5 mg/kg, respectively, compared with the control. R406 treatment at 10 mg/kg significantly reduces inflammation and swelling, decreases the progressive arthritis to a lower level in the passive anticollagen antibody-challenged mice, and delays the onset and reduces paw thickening and clinical arthritis by approximately 50% in the K/BxN serum transfer mice model. ^[1]
