Assay: Competitive Inhibition Binding Assay: A competitive inhibition binding assay was performed using membrane homogenates prepared from HEK-293 cells that express recombinant hMCR-1a or hMCR-4 (in each instance where the h prefix refers to human), or alternatively membrane homogenates from B16-F10 mouse melanoma cells containing endogenous murine MCR-1. In the examples that follow, all MCR-1 and MCR-4 values are for human recombinant receptors, unless otherwise noted. Assays were performed in 96 well polypropylene round-bottom plates (VWR catalog number 12777-030). Membrane homogenates were incubated with 0.1 nM [I125]-NDP-α-MSH (Perkin Elmer) and increasing concentrations of test peptides of the present invention in buffer containing 25 mM HEPES buffer (pH 7.5) with 100 mM NaCl, 2 mM CaCl2, 2 mM MgCl2, 0.3 mM 1,10-phenanthroline, and 0.2% bovine serum albumin. After incubation for 90 minutes at 37° C., the assay mixture was filtered onto GF/B Unifilter plates (Perkin-Elmer catalog number 6005177) and washed with 3 mL of ice-cold buffer per well. Filters were air dried and 35 uL of scintillation cocktail added to each well. Plates were counted in a Microbeta counter for bound radioactivity. Non-specific binding was measured by inhibition of binding of [I125]-NDP-α-MSH in the presence of 1 uM NDP-α-MSH. Maximal specific binding (100%) was defined as the difference in radioactivity (cpm) bound to cell membranes in the absence and presence of 1 uM NDP-α-MSH. Each assay was conducted in duplicate and the actual mean values are described, with results less than 0% reported as 0%. Ki values for peptides of the present invention were determined using Graph-Pad Prism curve-fitting software.

Target: Lysophosphatidic acid receptor 1 (SINGLE PROTEIN), Homo sapiens
UniProt: Q92633
Assay: In Vitro LPA1 Receptor Assay: Engagement of the LPA1 receptor by its ligand, oleoyl-L-α-lysophosphatidic acid (LPA), leads to the release of intracellular stores of calcium into the cytoplasm mediated through a Gq-driven increase in inositol triphosphate (IP3) levels. Gq is a heterotrimeric G protein subunit that activates phospholipase C.The ability of test compounds to prevent LPA-driven intracellular release of stored calcium from RH7777 cells expressing human LPA1 receptors was assayed by stimulating the cells with LPA in the presence of various test compounds to measure the test compounds' antagonism, i.e. activity in vitro. Approximately 10,000 cells in normal culture medium (Dulbecco's Modified Eagle Media, 10% Foetal Calf Serum) were dispensed per assay well in a black clear bottom collagen coated 384 well plate (Beckton Dickinson). Cells were allowed to settle for thirty minutes at room temperature before being incubated overnight at 37° C., 5% CO2. Sixteen to twenty hours after dispensing, the cells were loaded with a calcium-sensitive fluorescent dye by replacing the culture medium with assay buffer (1× Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH7.4) containing 1.25 mM probenecid and 1× Calcium 5 Reagent (Molecular Devices). Cells were incubated at 37° C. for one hour to allow for dye uptake. To test for antagonist activity, test compounds at a final concentration range between 0.32 nM-10 μM (diluted in assay buffer) were added to the assay wells and allowed to incubate for twenty five minutes. After incubation with test compounds the assay plate was placed in a FLIPR Tetra system (Molecular Devices) and LPA (diluted in assay buffer) was added to give a final concentration equivalent to its determined EC80 against LPA1 receptor. Ligand-dependent changes in intracellular calcium levels were determined by measuring changes in fluorescence of the dye over 515-575 nM following excitation over 470-495 nM.

Assay: Biological Assay: The compounds of the invention can be tested for their ability to inhibit LSD1. The ability of the compounds of the invention to inhibit LSD1 can be tested as follows. Human recombinant LSD1 protein was purchased from BPS Bioscience Inc (catalog reference number 50100: human recombinant LSD1, GenBank accession no. NM_015013, amino acids 158-end with N-terminal GST tag, MW: 103 kDa). In order to monitor LSD1 enzymatic activity and/or its inhibition rate by our inhibitor(s) of interest, di-methylated H3-K4 peptide (Anaspec) was chosen as a substrate. The demethylase activity was estimated, under aerobic conditions, by measuring the release of H2O2 produced during the catalytic process, using the Amplex Red hydrogen peroxide/peroxidase assay kit (Invitrogen).Briefly, a fixed amount of LSD1 was incubated on ice for 15 minutes, in the absence and/or in the presence of at least eight 3-fold serial dilutions of the respective inhibitor (e.g., from 0 to 75 uM, depending on the inhibitor strength). Tranylcypromine (Biomol International) was used as a control for inhibition. Within the experiment, each concentration of inhibitor was tested in duplicate. After leaving the enzyme interacting with the inhibitor, KM of di-methylated H3-K4 peptide was added to each reaction and the experiment was left for 30 minutes at 37° C. in the dark. The enzymatic reactions were set up in a 50 mM sodium phosphate, pH 7.4 buffer. At the end of the incubation, Amplex Red reagent and horseradish peroxidase (HPR) solution were added to the reaction according to the recommendations provided by the supplier (Invitrogen), and left to incubate for 5 extra minutes at room temperature in the dark. A 1 uM H2O2 solution was used as a control of the kit efficiency. The conversion of the Amplex Red reagent to resorufin due to the presence of H2O2 in the assay, was monitored by fluorescence (excitation at 540 nm, emission at 590 nm) using a microplate reader (Infinite 200, Tecan). Arbitrary units were used to measure level of H2O2 produced in the absence and/or in the presence of inhibitor. The maximum demethylase activity of LSD1 was obtained in the absence of inhibitor and corrected for background fluorescence in the absence of LSD1. The IC50 value of each inhibitor was calculated with GraphPad Prism Software.

Assay: Shift AlphaScreen Assay : The AlphaScreen Assay is modified to include the testing of inhibitors against ADAMTS-5 in the presence of 50% Lewis rat plasma in order to determine the effects of plasma protein binding on inhibitor potency. The ratio between the IC50 of the inhibitor against ADAMTS-5 in 50% Lewis rat plasma versus the IC50 of the inhibitor in buffer is calculated and is described as the plasma shift of the inhibitor. The assay is completed in the same manner using 10 nM ADAMTS-5 instead of 2.1 nM. A similar assay is used with dog ADAMTS-4 in the presence of 25% dog plasma.

Calcium dye fluorescence was monitored in FLIPR as the cells were challenged by adding 50 uL/well of BzATP (final concentration is 250 uM BzATP (human and rat) or 600 (mouse)). The fluorescence change was measured 180 seconds after adding the agonist.

Target: Serine/threonine-protein kinase pim-3 (SINGLE PROTEIN), Homo sapiens
UniProt: Q86V86
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
