Assay: Lyn Enzyme Activity : Lyn enzyme activity is measured using the IMAP (immobilized metal ion affinity-based fluorescence polarization) assay as outlined below.Lyn enzyme (Millipore catalog #14-510), is diluted to 250 mU/mL in KR buffer (10 mM Tris-HCl, 10 mM MgCl2, 0.01% Tween-20, 0.05% NaN3, 1 mM DTT, 2 mM MnCl2, pH 7.2).Serial dilution log 10 from 2 mM to 63.2 nM of test compounds are made in 100% DMSO. The dilutions in DMSO are then diluted 50-fold in KR-buffer of which 5 μl is used in the assay, leading to a final compound concentration range in the assay from 10 μM to 0.316 nM.5 μL/well of test compound in KR buffer (final DMSO concentration in the assay is 1%) is mixed with 5 μl/well of 250 mU/mL Lyn enzyme (final concentration in the assay is 62.5 mU/mL). Test compounds and Lyn enzyme are pre-incubated 60 minutes at room temperature, before adding 5 μL/well of 400 nM Fluorescin labeled substrate peptide (Blk/Lyntide substrate, e.g. #R7188/#R7233, Molecular Devices) in KR-buffer. Final peptide substrate concentration in assay is 100 nM. The kinase assay is started by adding 5 μL/well of 8 μM ATP in KR-buffer (final ATP concentration is 2 μM ATP, Km ATP in Lyn IMAP assay). Following incubation for 2 h at room temperature the enzyme reaction is stopped by adding 40 μL/well IMAP Progressive Binding Solution (according to suppliers (Molecular Devices) protocol using 75% 1× buffer A and 25% 1× buffer B with 1:600 Progressive Binding Solution). After 60 min incubation at room temperature in the dark the FP signal is read. Fluorescence at 535 nm is measured using parallel and perpendicular filters to determine differences in rotation due to binding of the phosphorylated substrate peptide to the beads. Values are calculated as percentage of the difference in readout (ΔmPi) of the controls with and without ATP. EC50 values are determined by curve fitting of the experimental results using Activity Base.

Assay: Caliper Assay: A kinase selectivity panel which measures substrate peptide phosphorylation was set-up for wild-type ALK2 (aa172-499), ALK2 FOP mutant (aa172-499 R206H), ALK1 (aa166-493), ALK5 (aa162-503) and ALK6 (aa168-495). The technology used for the described assay is based on the separation and quantification of substrate and product in an electrical field. In the course of the kinase reaction the peptide substrate is phosphorylated by a kinase. The transfer of a phosphate residue also causes the introduction of two additional negative charges and hence to a change in the net charge of the phospho-peptide compared to the unphosphorylated peptide. Due to this difference in charge the phosphorylated und unphosphorylated peptides migrate with different velocities in an electrical field.In the applied method, this separation takes place inside a chip that contains a complex capillary system for simultaneous analysis of 12 samples (12-sipper chip, Caliper Technologies Corp., Mountain View, USA). In order to allow the detection and quantification of the peptides in the capillary system, the peptides carry a fluorescent label (fluorescein). With this label the peptides can be quantified by fluorescence intensity through the instruments laser and detection system (LC3000, Caliper Life Sciences).The assays were performed in 384-well, low volume microtiter assay plates in a final reaction volume of 9 ul. Dose-response curves were generated by incubating 10 nM of each kinase together with 2 μm of the fluorescently labeled substrate peptide 5-Fluo-Ahx-KKYQAEEN-T-YDEYENKK-amid (10 mM stock solution in DMSO) in 50 mM Hepes pH 7.5, 0.02% Tween 20, 0.02% BSA, 1 mM DTT, 10 m Na3VO4, 10 mM If-Glycerolphosphate, 1 mM MgCl2, 12 mM MnCl2 (ALK1 and ALK6 7 mM) and 15 μm ATP for 60 min at 30° C. in the presence or absence of compound diluted in DMSO. Kinase reaction were terminated by adding 15 ul STOP buffer (100 mM HEPES pH 7.5, 5% DMSO, 0.1% Caliper coating reagent, 10 mM EDTA, and 0.015% Brij35.Plates with terminated kinase reactions were transferred to the Caliper LC3000 workstation (Caliper Technologies Corp., Mountain View, USA) for reading. The relative amount of phosphorylated peptide r, was calculated using the heights of the substrate peak, s, and the product peak, p: r=p/(p+s).

Assay: Inhibition Assays: Class I PI3-Ks can be either purchased (p110α/p85α, p110β/p85α, p110δ/p85α from Upstate, and p110γ from Sigma) or expressed as previously described (Knight et al., 2004). IC50 values are measured using either a standard TLC assay for lipid kinase activity (described below) or a high-throughput membrane capture assay. Kinase reactions are performed by preparing a reaction mixture containing kinase, inhibitor (2% DMSO final concentration), buffer (25 mM HEPES, pH 7.4, 10 mM MgCl2), and freshly sonicated phosphatidylinositol (100 μg/mL). Reactions are initiated by the addition of ATP containing 10 μCi of γ-32P-ATP to a final concentration of 10 or 100 μM and allowed to proceed for 5 minutes at room temperature. For TLC analysis, reactions are then terminated by the addition of 105 μL 1N HCl followed by 160 μL CHCl3:MeOH (1:1). The biphasic mixture is vortexed, briefly centrifuged, and the organic phase is transferred to a new tube using a gel loading pipette tip precoated with CHCl3. This extract is spotted on TLC plates and developed for 3-4 hours in a 65:35 solution of n-propanol:1M acetic acid.

Assay: Binding Activity Assay: The binding affinity of the present compounds to human 5-HT1A receptor, human D4 receptor, and human D2 receptor was measured in a manner mentioned below.CHO cell membrane fraction in which human 5-HT1A receptor, human D4 receptor, and human D2 receptor were expressed was purchased from PerkinElmer Co., Ltd. In the evaluation test of binding, the test compound dissolved in DMSO, each receptor membrane preparation diluted with buffer solution, and [3H] 8-OH-DPAT (for 5-HT1A receptor), [3H] dopamine (for D4 receptor), or [3H] spiperone (for D2 receptor) (all were obtained from PerkinElmer Co., Ltd.) were mixed, and each mixture was incubated at room temperature for 30 or 60 minutes. The nonspecific binding to each receptor was evaluated by a competition binding experiment in the presence of 10 μmol/L 8-OH-DPAT, 10 μmol/L dopamine, or 10 μmol/L spiperone, respectively. The radioactivity of each receptor-binding sample was measured with a liquid scintillation counter (PerkinElmer Co., Ltd.), the 50% inhibitory concentration was calculated, and Ki value was evaluated based on the dissociation constant and the substrate concentration caluculated in the saturated bond test, which was used as binding affinity.
