Target: cAMP and cAMP-inhibited cGMP 3',5'-cyclic phosphodiesterase 10A (SINGLE PROTEIN), Homo sapiens
UniProt: Q9Y233
Assay: Radioactive Assay: For assessing activity of compounds on PDE10 inhibition, the following modifications of the protocol described below are applied:  protein amount: 3 ng  protein concentration: 75 ug/ul.For all experiments the Phosphodiesterase [3H]cAMP SPA Enzyme Assay (TRKQ7090, GE Healthcare Europe GmbH) were used. The enzymatic activity of the PDE2 and the inhibitory potency of compounds was measured by the conversion of [3H]cAMP to [3H]AMP. [3H]AMP associate to the scintillator soaked yttrium-silicate beads resulting in an increase in scintillation events. Compounds that inhibit the respective enzymes decrease the generation of [3H]AMP and accordingly the number of counts detected.SF9 lysate containing PDE2A is incubated at room temperature for 1 h with [3H]cAMP and the reaction is terminated by addition of SPA beads in 18 mM zinc sulphate. The [3H]AMP bound to SPA beads is determined after at least 3 hours of sedimentation of the beads, the signal is recorded using the TopCount.

UniProt: O00408
Assay: Fluorescence Polarization Assay: The inhibition of PDE 2A or 10 enzyme activity was assessed using IMAP-Phosphodiesterase-cAMP fluorescence labeled substrate (Molecular Devices, Order No. R7506), IMAP TR-FRET screening express (Molecular Devices, Order No. R8160, the TR-FRET component will not be used) and PDE 2A or PDE10 protein expressed upon baculovirus infection in SF9 cells. The cells were incubated after infection for ~3 days and protein production was confirmed by Western Blot. The cells were collected by centrifugation and the pellet frozen in liquid nitrogen before it was resuspended in PBS containing 1% Triton X-100 and protease inhibitors. After 45 min incubation on ice, the cell debris was removed by centrifugation (13.000 rpm, 30 min). Since SF 9 cells do not express cAMP hydrolyzing enzymes to a high extent, no further purification of the protein was needed.All reactions were performed in 384 well plates, Perkin Elmer black optiplates and IMAP reaction buffer with 0.1% Tween20 (kit component).

Assay: Radioactive Assay: For assessing activity of compounds on PDE10 inhibition, the following modifications of the protocol described below are applied:  protein amount: 3 ng  protein concentration: 75 ug/ul.For all experiments the Phosphodiesterase [3H]cAMP SPA Enzyme Assay (TRKQ7090, GE Healthcare Europe GmbH) were used. The enzymatic activity of the PDE2 and the inhibitory potency of compounds was measured by the conversion of [3H]cAMP to [3H]AMP. [3H]AMP associate to the scintillator soaked yttrium-silicate beads resulting in an increase in scintillation events. Compounds that inhibit the respective enzymes decrease the generation of [3H]AMP and accordingly the number of counts detected.SF9 lysate containing PDE2A is incubated at room temperature for 1 h with [3H]cAMP and the reaction is terminated by addition of SPA beads in 18 mM zinc sulphate. The [3H]AMP bound to SPA beads is determined after at least 3 hours of sedimentation of the beads, the signal is recorded using the TopCount.

Assay: Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM 001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM 001526) were grown to confluency in DMEM (Hyclone, cat # SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat # SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2Kx G, 5 min at 4 C.), the supernatant was aspirated and the pellets frozen and stored at -80 C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL.

Target: Histone deacetylase 1 (SINGLE PROTEIN), Homo sapiens
UniProt: Q13547
Assay: Inhibition Assay: A similar assay procedure as described in Test 2 was used for HDAC1. Human recombinant full length HDAC1 expressed in a baculovirus expression system was purchased from BPS BioSciences (San Diego, Calif., U.S.A.). The substrate used in the HDAC1 assay was 5 uM of acetyl-Gly-Ala-Lys(acetyl)-AMC. TEST 2: Human recombinant HDAC4 was expressed in full length form (aa 2-1084) in Sf9 insect cells (obtained from ATCC) using baculovirus generated with Bac-to-Bac system (Invitrogen). Test compounds were serially diluted to reach final test concentrations from 0.000128 uM to 10 uM. HDAC4 and test compounds were incubated in 25 mM Tris buffer pH 8.0 containing 137 mM NaCl, 2.7 mM KCl, 1 mM MgCl2, 0.05% (w/v) bovine serum albumine and 0.005% (v/v) Triton-X-100 for 2 hours at room temperature in presence of 5 uM of acetyl-Gly-Ala-Lys(E-trifluoroacetyl)-AMC (AMC=7-amino-4-methyl coumarin) in a final volume of 9 ul. Control wells with HDAC4 only (positive control).
