Assay: Apoptosis Signal-Regulating Kinase Assay: The assay measures the phosphorylation level of a biotinylated peptide substrate by the ASK1 kinase using HTRF detection. This is a competitive, time-resolved fluorescence resonance energy transfer (TR-FRET) immunoassay, based on HTRF® KinEASE™-STK manual from Cisbio. Test compound, 1 μM STK3 peptide substrate, 4 nM of ASK1 kinase were incubated with 10 mM MOP buffer, pH. 7.0 containing 10 mM Mg-acetate, 0.025% NP-40, 1 mM DTT, 0.05% BSA and 1.5% glycerol for 30 minutes then 100 μM ATP was added to start the kinase reaction and incubated for 3 hr. Peptide antibody labeled with 1× Eu3+ Cryptate buffer containing 10 mM EDTA and 125 nM Streptavidin XL665 were added to stop the reaction and phosphorylated peptide substrate was detected using Envision 2103 Multilabeled reader from PerkinElmer. The fluorescence was measured at 615 nm (Cryptate) and 665 nm (XL665) and a ratio of 665 nm/615 nm was calculated for each well. The resulting TR-FRET level (a ratio of 665 nm/615 nm) was proportional to the phosphorylation level. Under these assay conditions, the degree of phosphorylation of peptide substrate was linear with time and concentration for the enzyme.

Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9P1W9
Assay: Homogeneous Time Resolved Fluorescence Assay (HTRF): The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF® (homogeneous time resolved fluorescence) technology to detect the product in a 384-well plate format. The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction. Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer]. Final concentrations either Pim-1 enzyme [5 pM], or Pim-2 enzyme [0.5 pM], DMSO [1%], BLC BAD (S112) [0.5 μM], ATP [1.5 μM], streptavidin:Allophycocyanin [0.002 mg/mL] and biotinylated-BAD (S112) mAb [100 pM]. Initial incubations were carried out at RT (22° C.) for 30 min for both Pim-1 and for Pim-2. Pim enzyme is added to compound in buffer, and plates are incubated of 30 min. Biotinylated BAD and ATP are added and plates are incubated for 1 h. A mixture of labeled p-BAD (S112) mAb and quench/detection buffer are added and incubated for 2 h. Fluorescence was measured by an HTRF® Envision microplate reader.

Assay: Cellular Assay: Assay b) HT29 cells (ECACC #85061109) were seeded into 384 well assay plates (Costar #3712) at a density of 6000 cells/well in 40 μl EMEM medium containing 1% L glutamine and 10% FBS and allowed to adhere overnight. The following morning compound of Formula (I) in 100% DMSO was added to assay plates by acoustic dispensing. After 1 h incubation at 37° C. and 5% CO2, 40 nl of 3 mM 4NQO in 100% DMSO was added to all wells by acoustic dispensing, except minimum control wells which were left untreated with 4NQO to generate a null response control. Plates were returned to the incubator for a further 1 h. Then cells were fixed by adding 20 μl of 3.7% formaldehyde in PBS solution and incubating for 20 mins at r.t. Then 20 μl of 0.1% Triton X100 in PBS was added and incubated for 10 minutes at r.t., to permeabalise cells. Then the plates were washed once with 50 μl/well PBS, using a Biotek EL405 plate washer. Phospho-Chk1 Ser 345 antibody (Cell Signalling Technology #2348) was diluted 150 fold in PBS containing 0.05% polysorbate/Tween and 15 μl was added to each well and incubated over night at r.t. The next morning plates were washed three times with 50 μl/well PBS, using a Biotek EL405 plate washer, and then 20 μl of secondary Ab solution, containing 500 fold diluted Alexa Fluor 488 Goat anti-rabbit IgG (Molecular Probes #A-11008) and 0.002 mg/ml Hoeschst dye (Molecular Probes #H-3570), in PBST, was added. After 2 h incubation at r.t., the plates were washed three times with 50 μl/well PBS, using a Biotek EL405 plate washer, and plates were then sealed with black plate seals until read. Plates were read using an ArrayScan VTI instrument, using an XF53 filter with 10× objective. A two laser set up was used to analyse nuclear staining with Hoeschst (405 nm) and secondary antibody staining of pChk1 (488 nm).

Target: Baculoviral IAP repeat-containing protein 2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q13490
Assay: DELFIA Assay: R3 domains of human XIAP (covering amino acids 241 to 356; XIAP BIR3) and cIAPl (covering amino acids 256 to 363; cIAPl BIR3) were expressed and purified from Ecoli as GST-fusion proteins. Peptide AVPIAQKSE-Lys(Biotin), representing the N-terminus of mature human SMAC (SMAC peptide), was used as interaction partner in the protein- peptide interaction assay.BIR3 domains (10 nM) were incubated with SMAC peptide (10 nM) in assay buffer (50 mM Tris, 120 mM NaCl, 0.1% BSA, 1 mM DTT, 0.05% TritonXlOO) for one hour at room temperature in the presence of inhibitiory compounds. The assay mixture was transferred to a strepatvidin coated plate and incubated for one hour at room temperature to allow binding of the biotinylated peptide and associated BIR3 domains to the plate. After several washing steps Eu labeled anti-GST antibody (e.g. Perkin Elmer DELFIA Eu-Nl- antiGST AD0250) was added to detect BIR3 domain-SMAC peptide interactions according to Perkin Elmer's instructions. Briefly, the antibody was added (dilution 1:5000 in Perkin Elmer DELFIA Assay Buffer 2013-01) and incubated for one hour. After 3 washing steps using Delfia Washing Buffer (Perkin Elmer DELFIA Wash 2013-05), Enhancement Solution (Perkin Elmer Enhancement Asolution 2013-02) was added and incubation continued for 10 minutes. Time resolved Europium fluoresecence was measured in a Wallac Victor using Standard assay settings.
