Assay: Calcium Flux Assay Using Fluorometric Imaging Plate Reader (FLIPR) Assay: Test compounds were prepared by adding 90 μL of HBSS/20 mM HEPES/0.1% BSA buffer to 2 μL of serially diluted compounds. To prepare serial dilutions, 10 mM stocks of compounds were prepared in 100% DMSO. The compound dilution plate was set up as follows: well #1 received 29 μL of stock compound and 31 μL DMSO. Wells 2-10 received 40 μL of DMSO. After mixing, 20 μL of solution from well #1 was transferred into well #2, followed by 1:3 serial dilutions out 10 steps. 2 μL of diluted compound was transferred into duplicate wells of 384 well "assay plate" and then 90 μL of buffer was added. After incubation, both the cell and "assay" plates were brought to the FLIPR and 20 μL of the diluted compounds were transferred to the cell plates by the FLIPR. Compound addition was monitored by the FLIPR to detect any agonist activity of the compounds. Plates were then incubated for 30 minutes at room temperature protected from light. After the incubation, plates were returned to the FLIPR and 20 μL of 4.5× concentrated agonist was added to the cell plates. During the assay, fluorescence readings were taken simultaneously from all 384 wells of the cell plate every 1.5 seconds. Five readings were taken to establish a stable baseline, then 20 μL of sample was rapidly (30 μL/sec) and simultaneously added to each well of the cell plate. The fluorescence was continuously monitored before, during and after sample addition for a total elapsed time of 100 seconds.

Assay: LANCE (Lanthanide Chelate Excite) TR-FRET (Time-resolved fluorescence resonance energy transfer) Assay: BTK enzymatic activity was determined with the LANCE (Lanthanide Chelate Excite) TR-FRET (Time-resolved fluorescence resonance energy transfer) assay. In this assay, the potency (IC50) of each compound was determined from an eleven point (1:3 serial dilution; final compound concentration range in assay from 1 uM to 0.017 nM) titration curve using the following outlined procedure. To each well of a black non-binding surface Corning 384-well microplate (Corning Catalog #3820), 5 nL of compound (2000 fold dilution in final assay volume of 10 uL) was dispensed, followed by the addition of 7.5 uL of 1x kinase buffer (50 mM Hepes 7.5, 10 mM MgCl2, 0.01% Brij-35, 1 mM EGTA, 0.05% BSA & 1 mM DTT) containing 5.09 pg/uL (66.67 pM) of BTK enzyme (recombinant protein from baculovirus-transfected Sf9 cells: full-length BTK, 6HIS-tag cleaved). Following a 60 minute compound & enzyme incubation, each reaction was initiated by the addition of 2.5 uL 1x kinase buffer containing 8 uM biotinylated "A5" peptide (Biotin-EQEDEPEGDYFEWLE-NH2) (SEQ ID NO: 1), and 100 uM ATP. The final reaction in each well of 10 uL consists of 100 pM hBTK, 2 uM biotin-A5-peptide, and 25 uM ATP. Phosphorylation reactions were allowed to proceed for 120 minutes. Reactions were immediately quenched by the addition of 20 uL of 1x quench buffer (15 mM EDTA, 25 mM Hepes 7.3, and 0.1% Triton X-100) containing detection reagents (0.626 nM of LANCE-Eu-W1024-anti-phosphoTyrosine antibody, PerkinElmer and 86.8 nM of Streptavidin-conjugated Dylight 650, Dyomics/ThermoFisher Scientific). After 60 minutes incubation with detection reagents, reaction plates were read on a PerkinElmer EnVision plate reader using standard TR-FRET protocol. Briefly, excitation of donor molecules (Eu-chelate:anti-phospho-antibody) with a laser light source at 337 nm produces energy that can be transferred to Dylight-650 acceptor molecules if this donor:acceptor pair is within close proximity. Fluorescence intensity at both 665 nm (acceptor) and 615 nm (donor) are measured and a TR-FRET ratio calculated for each well (acceptor intensity/donor intensity). IC50 values were determined by 4 parameter robust fit of TR-FRET ratio values vs. (Log10) compound concentrations.

Assay: Aequorin Functional Assay: Changes in intracellular calcium levels are a recognized indicator of G protein-coupled receptor activity. The efficacy of compounds of the invention to inhibit NKA-mediated NK-3 receptor activation was assessed by an in vitro Aequorin functional assay. Chinese Hamster Ovary recombinant cells expressing the human NK3 receptor and a construct that encodes the photoprotein apoaequorin were used for this assay. In the presence of the cofactor coelenterazine, apoaequorin emits a measurable luminescence that is proportional to the amount of intracellular (cytoplasmic) free calcium. Antagonist Testing: the antagonist activity of compounds of the invention is measured following pre-incubation (3 minutes) of the compound with the cells, followed by addition of the reference agonist (NKA) at a final concentration equivalent to the EC80 (3 nM) and recording of emitted light (FDSS 6000 Hamamatsu) over the subsequent 90-second period. The intensity of the emitted light is integrated using the reader software. Compound antagonist activity is measured based on the inhibition of the luminescence response to the addition of Neurokinin A.Â  Inhibition curves are obtained for compounds of the invention and the concentrations of compounds which inhibit 50% of reference agonist response (IC50) were determined (see results in table 5 below). The IC50 values shown in table 5 indicate that compounds of the invention are potent NK-3 antagonist compounds.

Assay: Cathepsin Enzyme Inhibition Assay: Enzyme activity is measured by observing the increase in fluorescence intensity caused by cleavage of a peptide substrate containing a fluorophore whose emission is quenched in the intact peptide. Assay buffer: 100 mM potassium phosphate pH 6.5, EDTA-Na 5 mM, Triton X-100 0.001%, DDT 5 mM. Enzymes (all at 1 nM): human and mouse Cathepsin S, Cat K, Cat B, Cat LSubstrate (20 uM): Z-Val-Val-Arg-AMC, except for Cat K which uses Z-Leu-Arg-AMC (both from Bachem). Z=Benzyloxycarbonyl. AMC=7-Amino-4-Methyl-Coumarin. Final volume: 100 uL. Excitation 360 nm, Emission 465 nm. Enzyme is added to the substance dilutions in 96-well microtitre plates and the reaction is started with substrate. Fluorescence emission is measured over 20 minutes, during which time a linear increase is observed in the absence of inhibitor.

Assay: [35S]GTPgammaS Binding Assay: The frozen cell membrane fraction prepared as described above was thawed before use, and the resultant was diluted with a buffer for a binding assay (final concentrations: 20 mM HEPES, 100 mM NaCl, 1 mM MgCl2, 3 uM GDP, 300 ug/mL saponin, 0.1% BSA). The compound of each example was added to a cell membrane fraction containing 1.8 to 3 ug/assay of membrane protein on a plate, followed by incubation at room temperature for 30 minutes. Thereafter, with glutamic acid (in a final concentration of 10 uM) added thereto, incubation was performed at room temperature for 15 minutes, and thereafter, [35S]GTPγS (in a final concentration of 0.8 kBq) and 588 ug WGA-SPA beads were added thereto, followed by incubation at room temperature for 1 hour. After the incubation, the plate was subjected to the centrifugal separation at 2,500 rpm and room temperature, and then, membrane cell binding radioactivity was measured with a top count. A [35S]GTPγS binding amount obtained in the presence of glutamic acid was defined as specific binding. On the basis of ratios of inhibiting the specific binding at various concentrations of the compounds of the respective examples, inhibition curves were obtained. Concentrations of the compounds of the respective examples at which the specific [35S]GTPγS binding amount was suppressed by 50% (IC50 values) were calculated on the basis of the inhibition curves.
