Assay: Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) Assay: The inhibition constant (Ki) is the dissociation constant of an enzyme-inhibitor complex or a protein/small molecule complex, wherein the small molecule is inhibiting binding of one protein to another protein or peptide. Where the Ki for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-XL) is greater than the limits of detection of the assay used. Where the binding selectivity ratio for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the selectivity of a particular compound for Bcl-2 over Bcl-XL is at least as great as the number indicated. Where the Ki for a compound is represented as < (less than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-2) is lower than the limit of detection of the assay used. Inhibition constants were determined using Wang's equation (Wang Z-X).

This procedure was repeated and the final pellet resuspended in HEPES-NaOH containing 0.1 mM EDTA and homogenized using the Polytron. Typically, aliquots of 2 ml membrane portions were stored at -80° C. With each new membrane batch the dissociation constant (Kd) was determined via a saturation curve. The TAAR1 radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine (described in WO 2008/098857) was used at a concentration equal to the calculated Kd value, that was usually around 2.3 nM, resulting in the binding of approximately 0.2% of the radioligand and a specific binding representing approximately 85% of the total binding. Nonspecific binding was defined as the amount of 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine bound in the presence of 10 uM unlabeled ligand. All compounds were tested at a broad range of concentrations (10 pM to 10 uM) in duplicates. The test compounds (20 ul/well) were transferred into a 96 deep well plate (TreffLab), and 180 ul of HEPES-NaOH (20 mM, pH 7.4) containing MgCl2 (10 mM) and CaCl2 (2 mM) (binding buffer), 300 ul of the radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine at a concentration of 3.3xKd in nM and 500 ul of the membranes (resuspended at 50 ug protein per ml) added. The 96 deep well plates were incubated for 1 hr at 4° C. Incubations were terminated by rapid filtration through Unifilter-96 plates (Packard Instrument Company) and glass filters GF/C (Perkin Elmer) presoaked for 1 hr in polyethylenimine (0.3%) and washed 3 times with 1 ml of cold binding buffer. After addition of 45 ul of Microscint 40 (PerkinElmer) the Unifilter-96 plate was sealed and after 1 hr the ratioactivity counted using a TopCount Microplate Scintillation Counter (Packard Instrument Company).

UniProt: Q9P1W9
Assay: Enzyme Assay: The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF® (homogeneous time resolved fluorescence) technology to detect the product in a 96-well plate format. The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction.Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 10-point dosing curve having a high dose of 1 uM. A reference compound was included on each assay plate in order to validate that plate; on

UniProt: O15379
Assay: Enzyme Assay: Enzyme activity of HDAC1,3 is determined using the substrate Ac-Lys-Tyr-Lys(Ac)-AMC while the enzyme activity of HDAC6 is assayed using the substrate Boc-lys(Ac)-AMC. The reaction is carried out in flat-bottom, 96-well, or 384-well microplates. After the substrate was deacetylated by HDACs, the product AMC which was obtained from hydrolysis by trypsin can generate fluorescence signal. Measurement is taken in using an multilabe plate reader a 355 nm excitation filter and a 460 nm emission filter. The initial rate of fluorescence should accurately reflect the rate of product formation and enzyme activity. Sample processing: The sample was dissolved in DMSO and kept at a low temperature. DMSO in the final system is limited under a low concentration which won't affect the enzyme activity.

Assay: Biochemical Assay: To measure inhibitory activity of FAK/PYK2 inhibitors, compounds were first prepare as a 1 mM stock in 100% DMSO and 3-fold serial dilution was performed in a 96-well plate (Corning, 3897) to generate 12 different concentration of 100× stock. A 5 μl of 100× stock of each concentration was added to wells containing 95 μl of 1× reaction buffer (40 mM Tris, pH7.5, mM MgCl2, 1 mM DTT and 1 mM CHAPS) to generate 5× stock. Then 2 μl of 5× stock of each concentration was added to a 384 wells-OptiPlate (PerkinElmer, 6007299). For FAK, 4 μl of 2.5 nM FAK, 1 μl of 8 μg/μl BSA and 1.5 μl of 666 nM ULight-poly Glu, Ala, Tyr (1:1:1) peptide substrate, prepared in above reaction buffer, were added to each well. The reaction was initiated by adding 1.5 μl of 33.3 μM ATP. The reaction was allowed to proceed for 120 min before being quenched with 5 μl of 40 mM EDTA stop buffer prepared in 1×LANCE detection buffer (PerkinElmer, CR97-100). For PYK2, 5 μl of 2 nM PYK2 and 1.5 μl of 666 nM ULight-poly Glu, Ala, Tyr (1:1:1) peptide substrate, prepared in above reaction buffer, were added to each well. The reaction was initiated by adding 1.5 μl of 46.6 μM ATP. The reaction was allowed to proceed for 40 min before being quenched with 5 μl of 40 mM EDTA stop buffer prepared in 1×LANCE detection buffer (PerkinElmer, CR97-100). Upon quenching of the reaction, 5 μl of 8 nM anti-phosphotyrosine antibody was added to each well and incubated for 60 minutes.
