- Binding Assay Receptor binding was performed using membrane fractions prepared from the HEK-293 cell line recombinantly expressing rat 5-HT7 receptors (NCBI accession NM_022938). Compound affinity for the rat 5-HT7 receptor subtype was evaluated by competitive radioligand binding assays using 5-carboxamido[3H]tryptamine ([3H]5-CT) (Amersham Biosciences, cat. 90000403) detection. HitHunter cAMP assays are in-vitro based competitive immunoassays. The assay was performed on the HEK-293 cell line stably transfected with r5-HT7 receptor. Cells were pre-incubated with test compounds for 10 minutes. For antagonist testing, the cells were then challenged with 100 nM 5-CT for 20 minutes. Cells were then lysed and cAMP measured according to manufacturers protocol (Amersham, cat. NET791250UC) or [3H]mesulergine (Amersham, cat. TRK1041). The assay was performed on membranes prepared from HEK-293 cells stably transfected with h5-HT6. Following centrifugation, membranes were resuspended and incubated for 60 min at room temperature with 1.7 nM [3H]LSD in the presence of increasing concentration of test compounds. Nonspecific binding was defined in the presence of 10 μM clozapine (Tocris, cat. TRK1068). Homogenized HEK-293 membranes expressing the human SERT were incubated in 50 mM Tris-HCl (pH 7.5), 120 mM NaCl, 5 mM KCl with [3H]-citalopram (3 nM) with or without test compounds. Nonspecific binding was determined in the presence of 10 μM fluoxetine. Radioactivity readouts and Ki values were performed as previously described for r5-HT7.
- 3H]-Spiperone Binding Assay CHO cells stably expressing human dopamine receptor type 2, long variant (hD2L), coupled to Gα16 protein (CHO-Gα16-hD2L) were re-suspended in 20 mM HEPES, 2 mM EDTA (pH 7.4), homogenised and centrifuged at 40,000 g (20 min, 4° C.). After re-suspension, homogenization and centrifugation as above, the final pellet was re-suspended in 20 mM HEPES, 100 mM NaCl, 10 mM MgCl2, 1 mM EDTA (pH 7.4) and aliquots were kept at −80° C. [3H]-Spiperone Binding experiments were performed in 96 deep-well polypropylene plates in 50 mM Tris/HCl, 120 mM NaCl, 5 mM KCl, 5 mM MgCl2 (pH 7.4). Compounds of invention were serially diluted in DMSO at 100 fold final concentrations in the assay (1% DMSO final in the assay). Displacement was performed in the presence of 0.08 nM [3H]-Spiperone. The reaction was initiated by the addition of membrane suspension (2 μg of protein for CHO-hD2 membranes) and lasted for 120 min at 23° C. in a final volume of 1000 μl. Non specific binding (NSB) was determined in the presence of 0.1 μM Spiperone. The binding reaction was stopped by rapid filtration through GF/B filterplates pre-soaked in 0.5% polyetylenimmine (PEI) using a Packard cell harvester. After washing with ice-cold 0.9% NaCl, the plate was left to dry before the addition of Microscint 20 (50 μl/well, PerkinElmer). Radioactivity was counted with a TopCount (PerkinElmer). Data were analysed by non-linear regression analysis using GraphPad Prism 5.0 (GraphPad Software) or XLfit Version 5.2.0.0 (Copyright 2006-2009 ID Business Solutions Ltd). Saturation binding experiments were performed similar to the competition binding experiments using a radioligand concentrations ranging from 0.011 to 3.0 nM. Ref: Durcan M. J. et al. (1995).
