Target: Serine/threonine-protein kinase mTOR (SINGLE PROTEIN), Homo sapiens
UniProt: P42345
Assay: Kinase Assay: The ability of compounds of Formula I to inhibit mTOR was determined in a radioactive filtration assay that measures the transfer of radiolabeled phosphate from [gamma-33P]ATP to the protein substrate 4E-BP1. Compounds were first prepared at 50x the top dose of 10,000 nM and serially diluted 3-fold in DMSO to give ten dose dilution series. Assays were conducted in 96-well polypropylene U-bottom plates in 40 uL (final volume) assay mixtures that contained 50 mM K+HEPES, pH 7.5, 1 mM EGTA, 0.005% Tween-20, 10 mM MnCl2, 2.5 mM DTT, 2% DMSO (final concentration with compound), 10 uM [gamma-33P]ATP (50 uCi/mL), 5 uM 4E-BP1 and 5 nM mTOR, which was added last to initiate the assay. Each plate contained appropriate high (uninhibited) and low (prequenched) controls as well as a reference compound. Incubations were carried out at 22 C. for 45 minutes, after which the reaction was stopped by the addition of 100 uL aliquots of 25% TCA.

Target: Regulator of G-protein signaling 8 (SINGLE PROTEIN), Homo sapiens
UniProt: P57771
Assay: Inhibitory Assay: FCPIA Characterization of RGS Inhibitory Activity: CCG-50014 (FIG. 1) was originally identified as a potential inhibitor of RGS8 and RGS16 in a polyplex high throughput screen to identify inhibitors of the RGS-Gα interaction [4]. This activity was confirmed by analyzing the effect of CCG-50014 on several different RGS proteins with freshly reordered compound using multiplexed FCPIA. CCG-50014 fully inhibited several different RGS proteins including RGS4, 8, 16, and 19, but did not have activity on RGS7 or a mutated form of RGS4 that lacks cysteine residues.

Assay: sAPPbeta Release Assay: SH-SY5Y cells were cultured in DMEM/F-12 with Glutamax, 10% FCS and 1% non-essential amino acids and cryopreserved and stored at −140° C. at a concentration of 7.5-9.5×106 cells per vial. Thaw cells and seed at a conc. of around 10000 cells/well in DMEM/F-12 with Glutamax, 10% FCS and 1% non-essential amino acids to a 384-well tissue culture treated plate, 100 μL cell susp/well. The cell plates were then incubated for 7-24 h at 37° C., 5% CO2. The cell medium was removed, followed by addition of 30 μL compound diluted in DMEM/F-12 with Glutamax, 10% FCS, 1% non-essential amino acids and 1% PeSt to a final conc. of 1% DMSO. The compounds were incubated with the cells for 17 h (overnight) at 37° C., 5% CO2. Meso Scale Discovery (MSD) plates were used for the detection of sAPPβ release. MSD sAPPβ plates were blocked in 1% BSA in Tris wash buffer (40 μL/well) for 1 h on shake at r.t. and washed 1 time in Tris wash buffer (40 μL/well). 20 μL of medium was transferred to the pre-blocked and washed MSD sAPPβ microplates, and the cell plates were further used in an ATP assay to measure cytotoxicity. The MSD plates were incubated with shaking at r.t. for 2 h and the media discarded. 10 μL detection antibody was added (1 nM) per well followed by incubation with shaking at r.t. for 2 h and then discarded. 40 μL Read Buffer was added per well and the plates were read in a SECTOR Imager.

Assay: TR-FRET Assay: The β-secretase enzyme used in the TR-FRET is prepared as follows: The cDNA for the soluble part of the human β-Secretase (AA 1-AA 460) was cloned using the ASP2-Fc 10-1-IRES-GFP-neoK mammalian expression vector. The gene was fused to the Fc domain of IgG1 (affinity tag) and stably cloned into HEK 293 cells. Purified sBACE-Fc was stored in −80° C. in Tris buffer, pH 9.2 and had a purity of 40%.The enzyme (truncated form) was diluted to 6 μg/mL (stock 1.3 mg/mL) and the substrate (Europium)CEVNLDAEFK(Qsy7) to 200 nM (stock 120 μM) in reaction buffer (NaAcetate, chaps, triton x-100, EDTA pH4.5). The robotic systems Biomek FX and Velocity 11 were used for all liquid handling and the enzyme and substrate solutions were kept on ice until they were placed in the robotic system. Enzyme (9 μl) was added to the plate then 1 μl of compound in dimethylsulphoxide was added, mixed and pre-incubated for 10 minutes. Substrate (10 μl) was then added, mixed and the reaction proceeded for 15 minutes at r.t. The reaction was stopped with the addition of Stop solution (7 μl, NaAcetate, pH 9). The fluorescence of the product was measured on a Victor II plate reader with an excitation wavelength of 340 nm and an emission wavelength of 615 nm. The assay was performed in a Costar 384 well round bottom, low volume, non-binding surface plate (Corning #3676). The final concentration of the enzyme was 2.7 g/ml; the final concentration of substrate was 100 nM (Km of 250 nM). The dimethylsulphoxide control, instead of test compound, defined the 100% activity level and 0% activity was defined by wells lacking enzyme (replaced with reaction buffer). A control inhibitor was also used in dose response assays and had an IC50 of 150 nM.

Assay: sAPPbeta Release Assay: SH-SY5Y cells were cultured in DMEM/F-12 with Glutamax, 10% FCS and 1% non-essential amino acids and cryopreserved and stored at −140° C. at a concentration of 7.5-9.5×106 cells per vial. Thaw cells and seed at a conc. of around 10000 cells/well in DMEM/F-12 with Glutamax, 10% FCS and 1% non-essential amino acids to a 384-well tissue culture treated plate, 100 μL cell susp/well. The cell plates were then incubated for 7-24 h at 37° C., 5% CO2. The cell medium was removed, followed by addition of 30 μL compound diluted in DMEM/F-12 with Glutamax, 10% FCS, 1% non-essential amino acids and 1% PeSt to a final conc. of 1% DMSO. The compounds were incubated with the cells for 17 h (overnight) at 37° C., 5% CO2. Meso Scale Discovery (MSD) plates were used for the detection of sAPPβ release. MSD sAPPβ plates were blocked in 1% BSA in Tris wash buffer (40 μL/well) for 1 h on shake at r.t. and washed 1 time in Tris wash buffer (40 μL/well). 20 μL of medium was transferred to the pre-blocked and washed MSD sAPPβ microplates, and the cell plates were further used in an ATP assay to measure cytotoxicity. The MSD plates were incubated with shaking at r.t. for 2 h and the media discarded. 10 μL detection antibody was added (1 nM) per well followed by incubation with shaking at r.t. for 2 h and then discarded. 40 μL Read Buffer was added per well and the plates were read in a SECTOR Imager.

InChIKey: HJMCUUCUCMHIEU-UHFFFAOYSA-N
Target: Amyloid-beta precursor protein (SINGLE PROTEIN), Homo sapiens
UniProt: P05067
Assay: TR-FRET Assay: The β-secretase enzyme used in the TR-FRET is prepared as follows: The cDNA for the soluble part of the human β-Secretase (AA 1-AA 460) was cloned using the ASP2-Fc 10-1-IRES-GFP-neoK mammalian expression vector. The gene was fused to the Fc domain of IgG1 (affinity tag) and stably cloned into HEK 293 cells. Purified sBACE-Fc was stored in −80° C. in Tris buffer, pH 9.2 and had a purity of 40%.The enzyme (truncated form) was diluted to 6 μg/mL (stock 1.3 mg/mL) and the substrate (Europium)CEVNLDAEFK(Qsy7) to 200 nM (stock 120 μM) in reaction buffer (NaAcetate, chaps, triton x-100, EDTA pH4.5). The robotic systems Biomek FX and Velocity 11 were used for all liquid handling and the enzyme and substrate solutions were kept on ice until they were placed in the robotic system. Enzyme (9 μl) was added to the plate then 1 μl of compound in dimethylsulphoxide was added, mixed and pre-incubated for 10 minutes. Substrate (10 μl) was then added, mixed and the reaction proceeded for 15 minutes at r.t. The reaction was stopped with the addition of Stop solution (7 μl, NaAcetate, pH 9). The fluorescence of the product was measured on a Victor II plate reader with an excitation wavelength of 340 nm and an emission wavelength of 615 nm. The assay was performed in a Costar 384 well round bottom, low volume, non-binding surface plate (Corning #3676). The final concentration of the enzyme was 2.7 g/ml; the final concentration of substrate was 100 nM (Km of 250 nM). The dimethylsulphoxide control, instead of test compound, defined the 100% activity level and 0% activity was defined by wells lacking enzyme (replaced with reaction buffer). A control inhibitor was also used in dose response assays and had an IC50 of 150 nM.
Measurement: IC50 = 7.3 nM (pChEMBL 8.140000343322754)
