Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
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

Assay: Binding Assay: The binding assays were performed by testing the ability of the new compounds to displace the radiolabeled synthetic non-selective cannabinoid agonist [3H]CP55940 (168 Ci/mmol; PerkinElmer) from the human CB1 (hCB1) or human CB2 (hCB2) receptors on membranes derived from stably transfected HEK-293 cells (PerkinElmer). Membranes were diluted in assay buffer (50 mM Tris-HCl, 1 mM EDTA, 1 mM MgCl2, 1 mg/ml BSA, pH=7.4). The amount of membrane was determined for each batch of membranes according to protein binding assay. The minimum amount of membrane that gave 50% specific binding was used for the binding assay. In most assays, binding was tested using 8 μg and 4 μg protein of hCB1 and hCB2 membranes, respectively. The tested compounds were dissolved in DMSO and diluted in assay buffer to a final concentration of 0.1% solvent. Total binding of [3H]CP55940 was evaluated with 1.5 nM to hCB1 and with 0.5 nM to hCB2, according to Kd affinity of [3H]CP55940 for the respective membranes. The ability of the tested compounds to displace [3H]CP55940 was evaluated first at a single concentration point of 100 nM for binding toward hCB2 or hCB1. In certain cases, the displacement was tested at compound concentrations ranging from 0.03 nM to 10 μM. Non-specific binding was measured by the addition of 1 μM of unlabelled CP55940 to the tubes. Binding assays were performed in triplicate in a total volume of 500 μl for 60 minutes at 30° C., in a shaking bath. Free and bound radioligands were separated by rapid filtration through GF/C filter plates (PerkinElmer) that had been presoaked with 0.1% Polyethylenimine (Sigma). Filters were shaken for 1 hour in 7 ml scintillation fluid (PerkinElmer) and radioactivity was determined by liquid scintillation counter (Wallac; PerkinElmer).

Assay: Electrophysiology Assay: Cells: The hNav1.7 expressing HEK-293 cells were plated on 35 mm culture dishes pre-coated with poly-D-lysine in standard DMEM culture media (Mediatech, Inc., Herndon, Va.) and incubated in a 5% CO2 incubator at 37° C. CuItured cells were used approximately 12-48 h after plating.Electrophysiology: On the day of experimentation, the 35 mm dish was placed on the stage of an inverted microscope equipped with a perfusion system that continuously perfuses the culture dish with fresh recording media. A gravity driven superfusion system was used to apply test solutions directly to the cell under evaluation. This system consists of an array of glass pipette glass connected to a motorized horizontal translator. The outlet of the shooter was positioned approximately 100 μm from the cell of interest.Whole cell currents were recorded using the whole-cell patch clamp configuration using an Axopatch 200B amplifier (Axon Instruments, Foster City Calif.), 1322A A/D converter (Axon Instruments) and pClamp software (v. 8; Axon Instruments) and stored on a personal computer. Gigaseals were formed and the whole-cell configuration was established in voltage clamp mode, and membrane currents generated by hNav1.7 were recorded in gap-free mode. Borosilicate glass pipettes have resistance values between 1.5 and 2.0 MΩ when filled with pipette solution and series resistance (<5 MΩ) was compensated 75-80%. Signals were sampled at 50 kHz and low pass filtered at 3 kHz.Voltage Protocols: After establishing the whole-cell configuration in voltage clamp mode, two voltage protocols were run to establish: 1) the holding potential; and 2) the test potential for each cell.

Assay: Binding of PEG-Nalbuphine assays: Specific binding is determined by subtraction of the cpm bound in the presence of 50-100× excess of cold ligand. Binding data assays were analyzed using GraphPad Prism 4.0 and IC50 is generated by non-linear regression from dose-response curves. Ki values were calculated using the Cheng Prusoff equation using the Kd values from saturation isotherms as follows: Ki=IC50/(1+[Ligand]/Kd).

Target: Leucine-rich repeat serine/threonine-protein kinase 2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q5S007
Assay: LanthaScreen Kinase Activity Assay: In the assay, 1 nM LRRK2 WT or 250 pM LRRK2 G2019S kinase is incubated with the test compound (typically at 0 to 30 μM) for 30 minutes before the kinase reaction is initiated by addition of 1.3 mM ATP and 0.4 μM fluorescein-LRRKtide. The reaction mixture (20 μl total volume) is incubated for 2 hours at 30° C. before the reaction is terminated by addition of 10 mM EDTA and 1 nM terbium-labelled anti-phospho-LRRKtide antibody (final volume 20 μl). The mixture is further incubated for 30 minutes at RT. TR-FRET is measured by excitation of the terbium-donor with 340 nm light and subsequent (delay time 100 μs) measurement of terbium and fluorescein emission at 495 nm and 520 nm, respectively, over a time window of 1000 μs. The measurement is repeated 10 times for fluorescein and 10 times for terbium emission with a 2000 μs time window between repeats. TR-FRET measurements are performed on a Biomek Synergy plate. The TR-FRET signal is calculated as the emission-ratio at 520 nm over 495 nm.
