Assay: Biotin Assay: A streptavidin-coated plate (Thermo Scientific, NUNC #436014) was washed three times with 300 μL of PBS-0.05% Tween solution. A biotinylated twenty-six amino acid peptide, corresponding to the BH3 domain of Bim, with the sequence biotin-(β)A-D-M-R-P-E-I-W-I-A-Q-E-L-R-R-I-G-D-E-F-N-A-Y-Y-A-R-R-amide (SEQ ID No. 14), hereafter referred to as biotin-Bim, was obtained (Tufts). The biotin-Bim peptide was diluted to 0.018 μg/mL (5 nM) in SuperBlock blocking buffer in PBS (Thermo Scientific, #37515), and 100 μL of this solution was incubated in the streptavidin-coated plate for 2.5 hours while shaking. Separately, a compound of Formula I or Formula II, which had been prepared in a 10 mM stock DMSO solution, was then incubated with 20 nM GST-Mcl-1 fusion protein in PBS. Compounds were tested in six three-fold dilutions ranging from 20 μM to 0.6 μM, 10 μM to 0.3 or 5 μM to 0.15 μM. In addition, Bim peptide (New England Peptide) was utilized as a control and tested in six-fold dilutions ranging from 100 nM to 3.3 nM. The streptavidin-coated plate which had previously been treated with biotin-Bim peptide was then washed three times with 300 μL of PBS-0.05% Tween solution. A solution of GST-MCL-1 and a compound of Formula I or Formula II (100 μL) was then added to the streptavidin-coated plate, with two wells utilized as controls (PBS buffer only, no GST-MCL-1 or biotin-Bim) and two wells as an alternative control (containing GST-MCL-1 but no biotin-Bim), and four three-fold dilutions of DMSO (0.2%, 0.06%, 0.02%, and 0.008%). All wells containing compounds of Formula I or Formula II were loaded in duplicate. The plate was incubated for 2 hours at RT, then washed three times with 300 μL of PBS-0.05% Tween solution. Anti-GST HRP (GE Healthcare, #RPN1236) is diluted 1:20,000 in freshly prepared PBS, 0.1% Tween20, and 0.5% BSA was then added to the plate and the plate was incubated for 30 minutes. The plate was then washed five times with 300 μL of PBS-0.05% Tween solution. A solution of color reagents A (stabilized peroxide solution) and B (stabilized chrommogen solution) (R&D Systems, #DY999) is mixed in a 1:1 ratio and added to each well in a quantity of 80 μL. The wells were allowed to develop until control wells containing DMSO are blue (approximately 5-10 minutes). A solution of ELISA stop solution (1M sulfuric acid, 20 μL per well) was then added. Absorbance at 450 nM was read on a Tecan GeniosPro plate reader.

Assay: Activity Assay: A human acute lymphoblastic lymphoma T cell line MOLT-4 (which can be purchased under ATCC No. CRL-1582 from ATCC) was cultured in an RPMI1640 medium containing 10% fetal bovine serum to obtain 5108 MOLT-4 cells. The cells were recovered by centrifugation and suspended in 10 ml of buffer solution A (25 mM Tris-HCl, 5 mM 2-mercaptoethanol, 2 mM benzamidine, 2 mM EDTA, and 0.1 mM 4-(2-aminoethyl)benzenesulfonyl hydrochloride, pH 7.5). The cells were homogenized using a Polytron homogenizer and centrifuged (4° C., 25,000 g, 10 minutes). Then, the supernatant was further ultracentrifuged (4° C., 100,000 g, 60 minutes). The obtained supernatant was filtered through a 0.2um filter to obtain a soluble fraction.HiTrap Q HP column (5 ml2, GE Healthcare Japan Corp.) equilibrated with buffer solution A was charged with the obtained soluble fraction. Phosphodiesterase was eluted with 300 ml of buffer solution A containing a linear gradient solution of 0 to 0.8 M NaCl to recover sixty 5-ml fractions. Each fraction was tested for cAMP-metabolizing phosphodiesterase activity. In each fraction, a fraction eluted as an active peak centered around 250 mM NaCl was collected from fractions that had cAMP metabolic activity and did not lose the metabolic activity by 10uM rolipram (PDE4 selective inhibitor) and 10uM milrinone (PDE3 selective inhibitor). In order to confirm whether or not PDE10A mRNA was expressed in the MOLT-4 cells, total RNA was prepared from the MOLT-4 cells according to a standard method and analyzed by RT-PCR using PDE10A gene-specific primers (PDE10A sense primer: 5'-TGCTCCATGGTGGAAGTGGA-3' (SEQ ID NO: 1) and PDE10A antisense primer: 5'-CAACTGGAAGCATGCGGTCA-3' (SEQ ID NO: 2)). As a result, PDE10A mRNA was detected from the total RNA of the MOLT-4 cells. On the other hand, total RNA was prepared from Jurkat cells, one type of human T cell, and similarly subjected to RT-PCR. As a result, PDE10A mRNA was rarely detected. An active peak centered around 250 mM NaCl was not observed in fractions obtained by the treatment of Jurkat cells in the same way as above. Eur J Biochem. 1999, 266 (3), 1118-2 has reported that PDE10A from the rat striatum and testis is eluted as an active peak centered around 250 mM NaCl.

Cancer., 121:1138-48 and Perez-Balado et al., 2007, J. Med. Chem., 50:2497-2505. Inhibition assays using nuclear extract were performed essentially as described in Herman et al., 2006, Nat. Chem. Biol., 2:551-558. Briefly, the purified HDACs or nuclear extract were incubated with an acetylated substrate in the absence of the compound to be assayed and with increasing concentrations of the compound. The rate of substrate deacetylation was measured under each condition, and half-maximal inhibitory concentration with regard to each HDAC was determined by standard means.

Assay: Aldosterone Synthase Inhibition Assay: The aldosterone synthase inhibition assay employs cynomolgus adrenal gland mitochondria as the source of aldosterone synthase (CYP11B2). Mitochondria are prepared from frozen cynomolgus monkey adrenal glands according to Method A described in by J. D. McGarry et al. (Biochem. J., 1983, 214, 21-28), with a final resuspension in the AT buffer described in R. Yamaguchi et al. (Cell Death and Differentiation, 2007, 14, 616-624), frozen as aliquots in liquid nitrogen and stored at -80° C. until use. Assays are performed in 96-well format in a final volume of 60 uL/well, containing 100 mM potassium phosphate, pH 7.4, 1% (v/v) DMSO, and additionally, 2 uM of corticosterone and 6 mg of mitochondrial protein. Reactions are started by the addition of NADPH to 1 mM and allowed to proceed for 60-90 minutes at 37° C. Reactions are terminated by the addition of 60 uL of acetonitrile. One hundred microliters are then transferred to a glass filter plate and centrifuged at 570xg.

Assay: Radio ABL1 (64-515) Assay: For determination of ABL kinase activity, the radiometric filter-binding assay was used. The assay was performed by mixing 10 uL of the compound pre-diluted with 10 uL of ATP (20 uM ATP with 0.1 uCi [γ-33P]-ATP) with the phospho-acceptor peptide poly[Ala6Glu2LysHBr5Tyr1]=polyAEKY) in 20 mM Tris/HCl pH 7.5, 1 mM DTT, 10 mM MgCl2, 0.01 mM Na3VO4, 50 mM NaCl. 10 uL of enzyme (ranging between 5 nM to 20 nM) was added to initiate the reaction. Pre-incubation of enzyme with compounds (when stated) was performed by exposing the enzyme to compounds prior to addition of the substrate mixture (ATP and/or peptide substrate). After 15 mM at room temperature, the reaction was stopped by the addition of 50 uL 125 mM EDTA, and the peptide-bound 33P separated on filter-plates (PVDF or MAIP; Millipore, Volketswil, Switzerland) prepared according to the manufacturer's instructions. Filter-plates were washed 3x with 0.5% H3PO4, followed by addition of 30 uL scintillation cocktail (Microscint, Perkin Elmer) per well and then analysed in a TopCount NXT scintillation counter (Perkin Elmer).
