Target: Serine/threonine-protein kinase pim-3 (SINGLE PROTEIN), Homo sapiens
UniProt: Q86V86
Assay: Enzyme Assay: 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 96-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 10-point dosing curve having a high dose of 1 uM. A reference compound was included on each assay plate in order to validate that plate; on

Assay: Radiometric Calcium Assay: The inhibition of TRPA1 receptor activation was measured as inhibition of allylisothiocyanate (AITC) induced cellular uptake of radioactive calcium. Test compounds were dissolved in DMSO to prepare 10 mM stock solution and then diluted using plain medium with 0.1% BSA and 1.8 mM CaCl2 to get desired concentration. Final concentration of DMSO in the reaction was 0.5% (v/v). Human TRPA1 expressing CHO cells were grown in F-12 DMEM medium with 10% FBS, 1% penicillin-streptomycin solution, and 400 ug/ml of G-418. Cells were seeded 24 h prior to the assay in 96 well plates so as to get 50,000 cells per well on the day of experiment. Cells were treated with test compounds for 10 min followed by addition of AITC at a final concentration of 30 micromolar and 5 uCi/ml 45Ca+2 for 3 min at 25° C. Cells were washed and lysed using buffer containing 1% Triton X-100, 0.1% deoxycholate and 0.1% SDS. Radioactivity in the lysate was measured in Packard Top count.

Target: Cytochrome P450 3A4 (SINGLE PROTEIN), Homo sapiens
UniProt: P08684
Assay: CYP3A4 Inhibition Assay: The CYP3A4 inhibition assay was performed using human liver microsomes and testosterone 6'-hydroxylation as a P450 isoform-specific marker. In a total volume of 150 uL, 14C-testosterone at a final concentration of 40 uM in a 100 mM phosphate buffer (pH 7.4) was incubated in a 96-well plate with 0.3 mg/mL of human liver microsomes in an Eppendorf thermomixer at 37° C. and 400 rpm. A 1.0 uL-aliquot of the 150-fold concentrated compound stock solution, prepared in DMSO, was added to yield final inhibitor concentrations of 0, 0.1, 0.5, 1.0, 5.0, 10, 25, and 50 uM. The reaction was initiated by addition of 15 uL of the NADPH-regenerating system containing the glucose-6-phosphate dehydrogenase and terminated after 7 min with a 75 uL-aliquot of methanol. After centrifugation at 465 g and 4° C. for 20 min, a 50 uL-aliquot of the supernatant was submitted to HPLC according to the method described below.

UniProt: P35968
Assay: PDGFRbeta: Automated FLIPR (Fluorometric Imaging Plate Reader) technology was used to screen for inhibitors of VEGF induced increases in intracellular calcium levels in fluorescent dye loaded endothelial cells. HUVEC (human umbilical vein endothelial cells) (Clonetics) were seeded in 384-well fibronectin coated black-walled plates overnight at 37° C./5% CO2. Cells were loaded with calcium indicator Fluo-4 for 45 minutes at 37° C. Cells were washed 2 times (Elx405, Biotek Instruments) to remove extracellular dye. For screening, cells were pre-incubated with test agents for 30 minutes, at a single concentration (10 uM) or at concentrations ranging from 0.0001 to 10.0 uM followed by VEGF165 stimulation (10 ng/mL). Changes in fluorescence at 516 nm were measured simultaneously in all 384 wells using a cooled CCD camera. Data were generated by determining max-min fluorescence levels for unstimulated, stimulated, and drug treated samples.
