Assay: Radioligand Binding Assay: Aliquots of membrane preparations were thawed at RT, resupended in assay buffer (D2, D3: 50 mM Tris-HCl, 120 mM NaCl, 5 mM MgCl2, 1 mM EDTA, 5 mM KCl, 1.5 mM CaCl2, pH=7.4; 5-HT2A: 50 mM Tris-HCl, 10 mM MgCl2, 1 mM EGTA, pH=7.4), homogenized with a Polytron for 20-30 sec at 12.000 rpm and adjusted to a final concentration of approximately 7.5 μg protein/well (D2, D3) and 15 μg protein/well (5-HT2A), respectively. The binding affinity (Ki) of the compounds was determined using radioligand binding. Membranes were incubated in a total volume of 200 μl with a fixed concentration of radioligand (final concentration approximately 0.7 nM [3H]-spiperone for D2, 0.5 nM [3H]-spiperone for D3, and 1.1 nM [3H]-ketanserin for 5-HT2A) and ten concentrations of test compound in ranging between 10 μM-0.1 nM for 1 h at RT.

Assay: Mobility-Shift kinase assay: Compounds of the examples provided herein were assessed for their ability to inhibit Syk kinase by utilizing Caliper Life Sciences' proprietary LabChip technology. The off-chip incubation mobility-shift kinase assay uses a microfluidic chip to measure the conversion of a fluorescent peptide substrate to a phosphorylated product. The reaction mixture, from a microtiter plate well, is introduced through a capillary sipper onto the chip, where the nonphosphorylated substrate and phosphorylated product are separated by electrophoresis and detected via laser induced fluorescence. The signature of the fluorescence signal over time reveals the extent of the reaction. The phosphorylated product migrates through the chip faster than the non-phosphorylated substrate, and signals from the two forms of the peptide appear as distinct peaks.

Compounds are serially diluted in kinase buffer (20 mM Tris-HCl, pH 7.4, 50 mM NaCl, 1 mM DTT, 1 mg/ml BSA) and added to the reaction mixture containing 2.5 ng/ml Cdk4/CyclinD1 or Cdk6/CyclinD3, 25 μM ATP, 10 μCi/ml [33P]-ATP, 0.1 μg/ml Rb in the kinase buffer. The mixture is incubated at room temperature for 1 hour and the proteins precipitated with an equal volume of 20% TCA. The plates are washed with 10% TCA according to the manufacturer's instruction and dried at room temperature. The amount of the phosphorylated Rb is determined with a TopCount (PerkinElmer).
