Target: Histamine H3 receptor (SINGLE PROTEIN), Homo sapiens
UniProt: Q9Y5N1
Assay: Guanosine 5'-O-(3-[35S]thio)triphosphate [GTP gamma S] Binding Assay: A GTP gamma S binding assay can be used to investigate antagonist properties of compounds in CHO cells (Chinese Hamster Ovary) transfected with human Histamine H3 receptor (hH3R). Membranes from CHO cells expressing hH3R (10 ug/well) are diluted in GTP gamma S assay buffer (20 mM Hepes, 10 mM MgCl2, 100 mM NaCl, pH 7.4) and preincubated with saponine (3 ug/ml), GDP (10 uM) and PVT-WGA SPA beads (125 ug/well) (Amersham) for 30 minutes. To determine antagonist activity, (R)-methyl histamine (30 nM) is added in 96 well SPA plate with [35S]GTP gamma S (0.2 nM) and various concentration of H3R antagonists. The GTP gamma S binding assay is started with addition of the mixture membrane/saponine/GDP and incubated for 90 minutes at room temperature. The amount of bound [35S]GTP gamma S is determined by using the MicroBeta Trilux counter (PerkinElmer). The percentage of [35S]GTP gamma S bound in each sample is calculated as a percentage of that bound control sample.

UniProt: P15056
Assay: ADP-Glo Kinase Assay: Inhibitor Concentration at 50% enzyme inhibition (IC50) values were calculated by quantifying the end-point ADP production from each kinase reaction using the ADP-Glo Kinase Assay (Promega, Madison, Wis.) as described by the manufacturer. Reactions were performed in Tris buffer (50 mM pH 7.5, RT) containing 20 mM MgCl2 and 0.1% Bovine Serum Albumin. Each assay was performed in 60 uL of the solution in 10x75 mm borosilicate glass test tubes and allowed to continuously shake during the duration of the assay. The total ADP generated was quantified by transferring 25 uL (2x) of each assay to a 96-well luminescence assay plate, followed by the addition of 25 uL of ADP-Glo Reagent (45 min incubation) to remove any remaining ATP. For luminescence readings, 50 uL of Kinase Detection Reagent (45 min incubation) was added to convert the ADP generated from the kinase reaction to ATP, and luminescent intensity was measured using a luciferase/luciferin reaction.

Rat neurons were isolated from the dorsal root ganglions and maintained in culture for 2 to 10 days in the presence of NGF (50 ng/ml) (culture media consisted of NeurobasalA supplemented with B27, glutamine and antibiotics). Small diameter neurons (nociceptors, 8-12 μm in diameter) were visually identified and probed with fine tip glass electrodes connected to an amplifier (Axon Instruments). The voltage clamp mode was used to assess the compound's IC50 holding the cells at −60 mV. In addition, the current clamp mode was employed to test the efficacy of the compounds in blocking action potential generation in response to current injections.

Assay: Assays for Detecting and Measuring of NaV Inhibition: 1) Pre-spotted compounds (in neat DMSO) into compound plates. Vehicle control (neat DMSO), the positive control (20 mM DMSO stock tetracaine, 125 μM final in assay) and test compounds were added to each well at 160× desired final concentration in neat DMSO. Final compound plate volume was 80 μL (80-fold intermediate dilution from 1 μL DMSO spot; 160-fold final dilution after transfer to cell plate). Final DMSO concentration for all wells in assay was 0.625%. 2) Prepared Hexyl Dye Solution. 3) Prepared cell plates. On the day of the assay, medium was aspirated and cells were washed three times with 100 μL of Bath1 Solution, maintaining 25 μL residual volume in each well. 4) Dispensed 25 μL per well of Hexyl Dye Solution into cell plates.
