UniProt: P14416
Assay: Functional Calcium Assay: CHO cells stably expressing human dopamine receptor type 2, long variant (hD2L), coupled to Gα16 protein (CHO-Gα16-hD2L) were seeded into black walled clear-base 384-well plates at a density of 8,000 cells per well and grown overnight at 37° C. After washing with the assay buffer (20 mM HEPES, 145 mM NaCl, 5 mM KCl, 5.5 mM glucose, 1 mM MgCl2 and 2 mM CaCl2, pH 7.4) containing 2.5 mM Probenecid, cells were incubated with the cytoplasmic Ca2+ probe Fluo-4 AM at 1 μM (final concentration), 37° C. for 60 min. Plates were washed three times as above and placed into a Fluorometric Imaging Plate Reader (FLIPR Tetra, Molecular Devices) to monitor cell fluorescence (ex=470-495 nm, em=515-575 nm) before and after the addition of different concentrations of test compounds. Compounds of invention were dissolved in DMSO and 200-fold diluted with assay buffer plus 0.01% Pluronic F-127. Cells were exposed first to test compounds for 10 min, then to a submaximal concentration of the hD2 receptor agonist dopamine (EC80, 50-140 nM). The fluorescence before compound addition (baseline) and before and after addition of agonist challenge was monitored. The peak of Ca2+ stimulation (baseline subtracted) was plotted versus the concentration of test compound and the curve fitted using a four-parameter logistic equation (XLfit) to assess the agonist/antagonist potency and maximal response.

Target: Phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta isoform (SINGLE PROTEIN), Homo sapiens
UniProt: P42338
Assay: Inhibition Assays: Class I PI3-Ks can be either purchased (p110α/p85α, p110β/p85α, p110δ/p85α from Upstate, and p110γ from Sigma) or expressed as previously described (Knight et al., 2004). IC50 values are measured using either a standard TLC assay for lipid kinase activity (described below) or a high-throughput membrane capture assay. Kinase reactions are performed by preparing a reaction mixture containing kinase, inhibitor (2% DMSO final concentration), buffer (25 mM HEPES, pH 7.4, 10 mM MgCl2), and freshly sonicated phosphatidylinositol (100 μg/mL). Reactions are initiated by the addition of ATP containing 10 μCi of γ-32P-ATP to a final concentration of 10 or 100 μM and allowed to proceed for 5 minutes at room temperature. For TLC analysis, reactions are then terminated by the addition of 105 μL 1N HCl followed by 160 μL CHCl3:MeOH (1:1). The biphasic mixture is vortexed, briefly centrifuged, and the organic phase is transferred to a new tube using a gel loading pipette tip precoated with CHCl3. This extract is spotted on TLC plates and developed for 3-4 hours in a 65:35 solution of n-propanol:1M acetic acid.

Assay: Radiometric Calcium Assay: The inhibition of TRPA1 receptor activation was measured as inhibition of allylisothiocyanate (AITC) induced cellular uptake of radioactive calcium. Test compounds were dissolved in DMSO to prepare 10 mM stock solution and then diluted using plain medium with 0.1% BSA and 1.8 mM CaCl2 to get desired concentration. Final concentration of DMSO in the reaction was 0.5% (v/v). Human TRPA1 expressing CHO cells were grown in F-12 DMEM medium with 10% FBS, 1% penicillin-streptomycin solution, and 400 ug/ml of G-418. Cells were seeded 24 h prior to the assay in 96 well plates so as to get 50,000 cells per well on the day of experiment. Cells were treated with test compounds for 10 min followed by addition of AITC at a final concentration of 30 micromolar and 5 uCi/ml 45Ca+2 for 3 min at 25° C. Cells were washed and lysed using buffer containing 1% Triton X-100, 0.1% deoxycholate and 0.1% SDS. Radioactivity in the lysate was measured in Packard Top count.

Assay: ELISA-Based Assay: Measurement of inhibition by compounds was performed using the HCV replicon system. Several different replicons encoding different HCV genotypes or mutations were used. In addition, potency measurements were made using different formats of the replicon assay, including different ways of measurements and different plating formats. See Jan M. Vrolijk et al., A replicons-based bioassay for the measurement of interferons in patients with chronic hepatitis C, 110 J. VIROLOGICAL METHODS 201 (2003); Steven S. Carroll et al., Inhibition of Hepatitis C Virus RNA Replication by 2'-Modified Nucleoside Analogs, 278(14) J. BIOLOGICAL CHEMISTRY 11979 (2003). However, the underlying principles are common to all of these determinations, and are outlined below.Stable neomycin phosphotransferase encoding replicons-harboring cell lines were used, so all cell lines were maintained under G418 selection prior to the assay. Potency was determined using a cell ELISA assay with an antibody to the replicons encoded NS3/4a protease. See Caterina Trozzi et al., In Vitro Selection and Characterization of Hepatitis C Virus Serine Protease Variants Resistant to an Active-Site Peptide Inhibitor, 77(6) J. Virol. 3669 (2003).

Cells were seeded at a density of 25000 cells/well (96-well clear bottom black walled plates) in 100 μl volume/well. On the day of the experiment, cell plates were washed with assay buffer, containing (in mM): 130 NaCl, 2 KCl, 1 CaCl2, 1 MgCl2, 10 HEPES, 5 glucose; pH 7.40 and 300 mOs. After the wash, cells were loaded with the Calcium-4 dye (Molecular Device) and incubated in the dark for 60 minutes. Test compounds were prepared at 250× the test concentration in neat DMSO. Intermediate 96-well compound plates were prepared by transferring 1.2 μL of the compound into 300 μL of assay buffer. A further 3× dilution occurred when transferring 50 μL/well of the compound plate to 100 μL/well in the cell plate. Cells were incubated with test compounds and dye for 30 minutes. Calcium dye fluorescence was monitored in FLIPR as the cells were challenged by adding 50 μL/well of BzATP (final concentration is 250 μM BzATP (human and rat)). The fluorescence change was measured 180 seconds after adding the agonist. Peak fluorescence was plotted as a function of BzATP concentration using Origin 7 software.

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: Cellular Assay: Assay d) MDA-MB-468 cells (human breast adenocarcinoma ##ATCC HTB 132) were seeded at 1500 cells/well in 40 μl of DMEM containing 10% FBS and 1% glutamine into Greiner 384 well black flat-bottomed plates. Cell plates were incubated for 18 h in a 37° C. incubator before dosing with compounds of formula (I) in 100% DMSO using acoustic dispensing. Compounds were dosed in a 12 point concentration range into a randomised plate map. Control wells were generated either by dosing of 100% DMSO (max signal) or addition of a reference compound (a PI3K-β inhibitor) that completely eliminated the pAKT signal (min control). Plates were incubated, at 37° C. for 2 h, cells were then fixed by the addition of 10 μl of a 3.7% formaldehyde solution. After 30 minutes the plates were washed with PBS using a Tecan PW384 plate washer. Wells were blocked and cells permeabilised with the addition of 40 μl of PBS containing 0.5% Tween20 and 1% Marvel™ (dried milk powder) and incubated for 60 minutes at r.t. The plates were washed with PBS containing 0.5% (v/v) Tween20 and 20 μl rabbit anti-phospho AKT Ser473 (Cell Signalling Technologies, #3787) in same PBS-Tween+1% Marvel™ was added and incubated overnight at 4° C. Plates were washed 3 times with PBS 0.05% Tween 20 using a Tecan PW384. 20 μl of secondary antibody Alexa Fluor 488 anti-Rabbit (Molecular Probes, #A11008) diluted in PBS+0.05% Tween20 containing 1% Marvel™ was added to each well and incubated for 1 h at r.t. Plates were washed three times as before then 20 μl PBS added to each well and plates sealed with a black plate sealer. The plates were read on an Acumen plate reader as soon as possible, measuring green fluorescence after excitation with 488 nm laser.
