Assay: Homogenous Time-Resolved Fluorescence Assay (HTRF2 Assay): The standard assay conditions for the in vitro HTRF assay consisted of a 50 ul total reaction volume in black 384-well Costar polypropylene plates in 1×PBS buffer pH 7.4, 1 mM DTT, 0.1% BSA, 2.5 nM GST-hMDM2 (aa 1-188), 5 nM biotinylated-p53 (aa 1-83), 1.8 nM SA-XLent (Cisbio; Bedford, Mass.), 0.6 nM anti-GST cryptate monoclonal antibody (Cisbio; Bedford, Mass.) and 200 mM KF. Amino acid residues 1-188 of human MDM2 were expressed as an amino-terminal glutathione-S-transferase (GST) fusion protein (GST-hMDM2) in Escherichia coli. Residues 1-83 of human p53 were expressed as an amino-terminal AviTag™-TrxA-6×His fusion protein (biotinylated p53) in E. coli. Each protein was purified from cell paste by affinity chromatography.Specifically, 10 uL of GST-hMDM2 was incubated with 10 ul of diluted compound (various concentrations, serially diluted) in 10% DMSO for 20 minutes at room temperature. 20 uL of biotinylated-p53 was added to the GST-hMDM2+compound mixture, and then incubated at room temperature for 60 min. 10 uL of detection buffer consisting of SA-XLent, anti-GST cryptate antibody and KF was added to GST-hMDM2, biotinylated-p53 and compound reaction and left at room temperature to reach equilibrium for >4 hrs. The final concentration of DMSO in the reaction was 2%. Time-resolved fluorescence readings were measured on a microplate multilabel reader. Percentage of inhibition was calculated relative to nutlin-3. All assay conditions remained the same as described above, with the exception of the following changes in reagent concentrations: 0.2 nM GST-hMDM2 (1-188), 0.5 nM biotinylated-p53 (1-83), 0.18 nM SA-XLent, and 100 mM KF.

Radioligand binding experiments were conducted in 96 polypropylene well plates in a total volume of 200 μl. All reagents were dissolved in assay binding buffer (PBS with calcium and magnesium, SIGMA), except compounds that were dissolved in DMSO 100%. Non-specific binding (NSB) was measured in the presence of 1 μM atropine. [3H]-NMS was used as the radioligand at a concentration of 1 nM for M2, M3 and M5 and 0.3 nM for M1 and M4. [3H]-NMS and antagonists were incubated with membranes that express human muscarinic receptors M1, M2, M3, M4 and M5 at concentrations of 8.1, 10, 4.9, 4.5 and 4.9 μg/well, respectively. After an incubation period of two hours with gentle shaking, 150 μl of the reaction mix were transferred to 96 GF/C filter plates (Millipore), previously treated with wash buffer (Tris 50 mM; NaCl 100 mM; pH: 7.4), containing 0.05% PEI (Sigma) during one hour. Bound and free [3H]-NMS were separated by rapid vacuum filtration in a manifold from Millipore and washed four times with ice cold wash buffer. After drying 30 min, 30 μl of OPTIPHASE Supermix were added to each well and radioactivity quantified using a Microbeta microplate scintillation counter.

Assay: Kinase Assay: The kinase assay was performed in V-bottom 384-well plates. The final assay volume was 30 ul prepared from 15 ul additions of enzyme, substrates (fluoresceinated peptide FL-AHA-KRRRAL-PSER-VASLPGL-OH and ATP) and test compounds in assay buffer (20 mM HEPES pH 7.4, 30 mM MgCl2, 0.015% Brij35 and 4 mM DTT). The reaction was incubated at room temperature for 22 hours and terminated by adding 45 ul of 35 mM EDTA to each sample. The reaction mixture was analyzed on the Caliper LABCHIPÂ®3000 (Caliper, Hopkinton, Mass.) by electrophoretic separation of the unphosphorylated substrate and phosphorylated product Inhibition data were calculated by comparison of the no enzyme control reactions for 100% inhibition and vehicle-only reactions for 0% inhibition. The final concentration of reagents in the assay were 200 pM CK1ε or CK1δ, 50 uM ATP, 1.5 uM FL-AHA-KRRRAL-PSER-VASLPGL-OH, and 1.6% DMSO. Dose response curves were generated to determine the concentration required to inhibit 50% of the kinase activity (IC50). Compounds were dissolved at 10 mM in dimethylsulfoxide (DMSO) and evaluated at eleven concentrations. IC50 values were derived by non-linear regression analysis.

Assay: cAMP Assay: CHO cells expressing human CB1 or CB2 receptors are seeded 17-24 hours prior to the experiment 50.000 cells per well in a black 96 well plate with flat clear bottom (Corning Costar #3904) in DMEM (Invitrogen No. 31331), 1×HT supplement, with 10% fetal calf serum and incubated at 5% CO2 and 37° C. in a humidified incubator. The growth medium was exchanged with Krebs Ringer Bicarbonate buffer with 1 mM IBMX and incubated at 30° C. for 30 min. Compounds were added to a final assay volume of 100 μl and incubated for 30 min at 30° C. Using the cAMP-Nano-TRF detection kit the assay (Roche Diagnostics) was stopped by the addition of 50 μl lysis reagent (Tris, NaCl, 1.5% Triton X100, 2.5% NP40, 10% NaN3) and 50 μl detection solutions (20 μM mAb Alexa700-cAMP 1:1, and 48 μM Ruthenium-2-AHA-cAMP) and shaken for 2 h at room temperature. The time-resolved energy transfer is measured by a TRF reader (Evotec Technologies GmbH), equipped with a ND:YAG laser as excitation source. The plate is measured twice with the excitation at 355 nm and at the emission with a delay of 100 ns and a gate of 100 ns, total exposure time 10 s at 730 (bandwidth 30 nm) or 645 nm (bandwidth 75 nm), respectively. The FRET signal is calculated as follows: FRET=T730-Alexa730-P(T645-B645) with P=Ru730-B730/Ru645-B645, where T730 is the test well measured at 730 nM, T645 is the test well measured at 645 nm, B730 and B645 are the buffer controls at 730 nm and 645 nm, respectively. cAMP content is determined from the function of a standard curve spanning from 10 μM to 0.13 nM cAMP.
