Assay: In Vitro Inhibition Assay: ITK and JAK3 Kinase assay procedures:Enzyme was incubated with substrate peptide in reaction buffer in the presence and absence of test compounds or Staurosporine. All additions were done on ice, followed by the addition of ATP mix. Wells were uniformly mixed using an Eppendorff plate shaker and incubated at 30° C. for 20 min, and stopped by the addition of 5 μL of 3% phosphoric acid. Volume was increased to 100 μL by adding 0.8% phosphoric acid which was then transferred to PC filter mats (Millipore), pre-equilibrated with 70% ethanol and water. Plates were washed thrice with 100 μL 0.8% phosphoric acid and dried for an hour at 60° C. 100 μL scintillation fluid was added into each well and reading taken in Perkin Elmer TOPCOUNT beta counter. The data analysis was performed by averaging the duplicate top count readings for each standard, negative, positive control (enzyme control) and samples and subtracting the average negative control from each reading which results in corrected values.

Assay: FRET-Based Assay: The HCV NS3 protease functions have been extensively studied and are considered as potential targets for antiviral therapy: see for example the many references listed in the introductory section of this application. Therefore, the activity of the compounds of the invention as anti-HCV agents was assessed using a full length HCV NS3 protease.The protease activity of the full length NS3/4a was measured using a FRET-based assay utilizing a peptide substrate derived from the NS4A/B cleavage site (Anaspec) and labelled at one end with a quencher (QXL520) and at the other with a fluorophore (5-FAMsp). NS3/4a (produced in-house by literature methods) was incubated with test compounds and peptide substrate in 50 mM Tris pH8, 20 mM DTT, 1% CHAPS, 10% glycerol and 5% DMSO. The reaction was followed by monitoring the change in fluorescence on a Molecular Devices Gemini plate reader for 30 minutes at room temperature.

Assay: In Vitro Radioactive Assays of CETP-Catalyzed CE and TG Transfer (RTA Assay): Radiolabeled donor particles are generated by first combining 100 μl of 200 μM butylated hydroxyl toluene in CHCl3, 216 μL of 21.57 mM DOPC in EtOH, and either 500 μCi [3H]-triolein (Perkin Elmer #NET-431) or 500 μCi [3H]-cholesteryl oleate (GE #TRK886) in a glass tube. Reagents are mixed, dried under nitrogen, and then resuspended in 2 mL of 50 mM Tris, 27 μM EDTA at pH 7.4. After a brief vortex, the solution is sonicated until clear and mixed with 20 mL of fresh human serum. The mixture is incubated overnight at 37° C. The [3H] labeled LDL substrate is separated at 1.063 g/ml density by sequential ultracentrifugal flotation in NaBr according to the method by (Havel, Eder et al. 1955; Chapman, Goldstein et al. 1981). Once isolated the particles are dialyzed 3× in CETP buffer (50 mM Tris, pH 7.4, 100 mM NaCl, 1 mM EDTA). Human HDL is purchased from Intracel and used as the acceptor particles. Transfer assays are performed in a 96 or 384-well v-bottom polypropylene plate. For the RTA using recombinant CETP (2% RTA), an assay cocktail is prepared with the final concentrations 128 μg/mL HDL, 20 nM rCETP, 2% human serum, and 1×CETP buffer. 1 μL of each test compound diluted in DMSO is added to 47 μL of assay cocktail per well and incubated at 37° C. for 1 hour. To initiate the transfer reaction, 2 μL radiolabeled LDL is added. After an additional 60 min of incubation at 37° C., the transfer action is terminated by precipitation of LDL with an equal volume of 20% W/V PEG 8000. The plates are centrifuged at 2000 rpm for 30 minutes at 4° C. A 40 μL aliquot of the HDL-containing supernatant is transferred to a Packard Optiplate™ with 200 μL of MicroScint™ 20. After mixing, plates are counted by liquid scintillation.

PARP reactions contained 1.5 uM [3H]-NAD+ (1.6 uCi/mmol), 200 nM biotinylated histone H1, 200 nM sIDNA, and 1 nM PARP enzyme. Auto reactions utilizing SPA bead-based detection were carried out in 100 uL volumes in white 96 well plates. Reactions were initiated by adding 50 ul of 2xNAD+ substrate mixture to 50 uL of 2x enzyme mixture containing PARP and DNA. These reactions were terminated by the addition of 150 uL of 1.5 mM benzamide (~1000-fold over its IC50). 170 uL of the stopped reaction mixtures were transferred to streptavidin Flash Plates, incubated for 1 hour, and counted using a TopCount microplate scintillation counter.

UniProt: P11309
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 standard curve using the compound of Example 135, WO2005/116035 at a top concentration of 150 μM is also prepared on each test plate. High percentage effect (HPE) is defined by 150 μM of the compound of Example 135, WO2005/116035 and 0% effect (ZPE) is defined by 100% DMSO. Plates containing 1 μl of serially diluted compound, standard and HPE/ZPE are diluted 1/66 in assay buffer (PBS minus Ca2+, minus Mg2+ with 0.05% pluronic F127) using a Wellmate. Using a Platemate Plus, 5 μl of 1/66 diluted test compounds is then transferred to the cell plate and allowed to reach equilibrium by incubating for 30 min at room temperature before addition of agonist stimulus: 10 μl/well of 2 nM (0.571 nM FAC) of the cognate neurotrophin (Peprotech) diluted in agonist buffer (HBSS with 0.25% BSA). Final assay concentration of the test compounds is 8.66 μM, (the compound of Example 135, WO2005/116035 FAC is 0.325 μM). The plates are left at room temperature for a further 2 hours before addition of 10 μl of the DiscoveRx PathHunter detection reagent (made up by adding 1 part Galacton Star, 5 parts Emerald II and 19 parts Cell Assay Buffer as per the manufacturer's instructions). After reagent addition, plates are covered and incubated at room temperature for 60 minutes. Luminescence signal is read using an Envision.

Assay: LCMS Assay: The MGAT enzyme reactions were performed in Corning FALCON® 96-well Polypropylene plates, in a total volume of 60 μL of 50 mM Potassium Phosphate buffer pH 7.4, containing a final concentration of 100 μM 2-oleoylglycerol, 15 μM oleoyl-Coenzyme A and 0.0013 μg/μL Human or Mouse MGAT-2 or 0.0026 μg/μL Rat recombinant MGAT-2 membranes expressed in Sf9 cells. Assay plates were run through a fully automated robotics system and shaken for 5 seconds every minute for a total 10 minutes. The reactions were then quenched with 120 μL of ice cold methanol containing 1 μg/mL 1,2-distearoyl-rac-glycerol as the internal standard. Plates were shaken for 2 minutes and spun down to remove protein precipitation. After the spin, samples were transferred to LC/MS compatible PCR plates. For LC/MS analysis, a ThermoFisher Surveyor pump, utilizing a Waters Symmetry C8, 50×2.1 mm column, was used for the chromatography of enzyme products. The buffer system consists of 0.1% formic acid in water with a mobile phase consisting 0.1% formic acid in methanol. The shallow gradient is 90-100% mobile phase in 0.2 min with a total run time of 2.3 min. The first 0.5 minutes of each injection was diverted to waste to eliminate the presence of Phosphate buffer in the enzymatic reaction. The column was run at 0.6 mL/min and a temperature of 65° C.
