Membranes were purchased from Perkin Elmer. Test compounds were then added to each well and then [3H] CP 55, 940 (0.4 nM final well concentration) in assay buffer (50 mM Tris-HCl pH 7.4, 5 mM MgCl2 and 0.5 mg/ml (0.05%) Ultra fatty acid free BSA) was added. Samples were mixed and incubated for 90 min at 30° C. in the Greiner V Bottom Polypropylene plate. After incubation, assay reagents were transferred to a blocked 384 well polypropylene filter plates. The binding reaction was stopped by filtration and washed seven times with ice cold rinse buffer. Filter plates were then dried overnight at room temperature. The next day, plate bottoms were sealed with plate tape and 15 ul MicroScint 20 was added to each well. Plates were incubated for 2 h and radioactivity was measured by Topcount.Binding Assay: Experimental Procedure CB-1 Membrane Binding: Into Greiner V bottom polypropylene plates, hCB1-CHO-K1 membranes (2 ug/well final concentration) in assay buffer (50 mM Tris-HCl pH 7.4, 5 mM MgCl2 and 0.5 mg/ml (0.05%) Ultra fatty acid free BSA) were dispensed.

The growth medium was exchanged with Krebs Ringer Bicarbonate buffer with 1 mM IBMX and incubated at 30.degree. C. for 30 min Compounds were added to a final assay volume of 100 ul 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 ul lysis reagent (Tris, NaCl, 1.5% Triton X100, 2.5% NP40, 10% NaN.sub.3) and 50 ul detection solutions (20 uM mAb Alexa700-cAMP 1:1, and 48 uM 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.

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.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.

Briefly, 25 μg of mouse brain homogenates were incubated for 30 minutes at 30° C. with 0.1 nM [35S]GTPγS, 10 μM GDP, and either cannabinoid+/−antagonist, 10 μM unlabeled GTPγS (non-specific binding) or vehicle (total binding), in triplicate, in a volume of 1 mL of buffer containing 20 mM HEPES, 10 mM MgCl2, 100 mM NaCl, 20 units/L adenosine deaminase, 0.05% BSA and the appropriate DMSO (0.1%) and/or ethanol (<0.2%) vehicle. Assay buffer containing 100 mM KCl, instead of 100 mM NaCl, was used to increase basal G-protein activity in experiments examining inverse agonism. Reactions were terminated by quick vacuum filtration through Whatman GF/B glass fiber filters, followed by five washes with ice-cold buffer (20 mM HEPES, 0.05% BSA). Filters were immediately placed into 7 mL scintillation vials to which 4 mL of ScintiVerse™ BD Cocktail scintillation fluid was added. Bound radioactivity was determined after overnight incubation at room temperature and shaking by liquid scintillation spectrophotometry with an efficiency of 93% (Tri Carb 2100 TR Liquid Scintillation Analyzer, Packard Instrument Company, Meriden, Conn.).[35S]GTPγS Binding Assay: [35S]GTPγS binding was performed as previously described [Brents et al., PLoS One, 6:e21917].

The growth medium was exchanged with Krebs Ringer Bicarbonate buffer with 1 mM IBMX and incubated at 30.degree. C. for 30 min Compounds were added to a final assay volume of 100 ul 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 ul lysis reagent (Tris, NaCl, 1.5% Triton X100, 2.5% NP40, 10% NaN.sub.3) and 50 ul detection solutions (20 uM mAb Alexa700-cAMP 1:1, and 48 uM 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.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.times.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.
