Assay: TR-FRET Assay for BIR2 and BIR3: Ten nanomolar of 6× Histidine-tagged BIR2 domain, corresponding to amino acids 124-240 of XIAP, or BIR3 domain, corresponding to amino acids 241-356 of XIAP, was mixed with 20 nM of the peptide AVPIAQKSEK-(c-biotin)-OH 1:2 TFA, in the presence of 50 mM Tris-Cl, pH 7.5, 100 mM NaCl, 1 mM dithiothreitol (DTT) and 0.1 mg/mL bovine serum albumin (BSA). Following a 45 min. incubation at 37° C., Europium-Streptavidin and Allophycocyanin conjugated anti-Histidine antibody were added to a final concentration of 1.5 nM and 15 nM, respectively. Time-resolved fluorescence resonance energy transfer (TR-FRET) signals were measured 1 hour later at room temperature. Test compound potency was assessed at 10 serially diluted concentrations. Percentage of inhibition at each concentration was determined to generate an IC50 value for each test compound.

Assay: In Vitro Kinase Assay: In vitro kinase analysis was performed by using HTScan EGF Receptor Kinase Assay Kit (#7909) and HTScan HER2/ErbB2 Kinase Assay Kit (#7058) from Cell Signaling Technology Company. Operation steps refer to the specification of the used kits, and the method was used to measure the inhibition effects of the compound to be tested on substrate peptide phosphorylation of EGFR or Her2 receptor tyrosine kinase. At room temperature, ATP and substrate peptide as well as the compound to be tested were incubated in kinase reaction buffer, after a period of incubation, a stop buffer was added to terminate the reaction and the sample was transferred to a streptavidin-coated 96-well plate, the plate was washed and the phosphorylation level of substrate peptide was detected by using HRP-marked antibody against substrate phosphorylation, colorated with TMB, terminated the reaction with 2M sulfuric acid. Absorption at 450 nm wavelength was detected, and IC50 value (μM) was calculated.

Assay: TR-FRET Assay for BIR2 and BIR3: Ten nanomolar of 6× Histidine-tagged BIR2 domain, corresponding to amino acids 124-240 of XIAP, or BIR3 domain, corresponding to amino acids 241-356 of XIAP, was mixed with 20 nM of the peptide AVPIAQKSEK-(c-biotin)-OH 1:2 TFA, in the presence of 50 mM Tris-Cl, pH 7.5, 100 mM NaCl, 1 mM dithiothreitol (DTT) and 0.1 mg/mL bovine serum albumin (BSA). Following a 45 min. incubation at 37° C., Europium-Streptavidin and Allophycocyanin conjugated anti-Histidine antibody were added to a final concentration of 1.5 nM and 15 nM, respectively. Time-resolved fluorescence resonance energy transfer (TR-FRET) signals were measured 1 hour later at room temperature. Test compound potency was assessed at 10 serially diluted concentrations. Percentage of inhibition at each concentration was determined to generate an IC50 value for each test compound.

The sequence AVPIAQKSEK was identified as optimal for using in an assay. The peptide sequence was derivatized with biotin to provide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA as the substrate for the TR-FRET assay. Ten nanomolar of 6× Histidine-tagged BIR2 domain, corresponding to amino acids 124-240 of XIAP, or BIR3 domain, corresponding to amino acids 241-356 of XIAP, was mixed with 20 nM of the peptide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA, in the presence of 50 mM Tris-C1, pH 7.5, 100 mM NaCl, 1 mM dithiothreitol (DTT) and 0.1 mg/mL bovine serum albumin (BSA). Following a 45 mM incubation at 37° C., Europium-Streptavidin and Allophycocyanin conjugated anti-Histidine antibody were added to a final concentration of 1.5 nM and 15 nM, respectively. Time-resolved fluorescence resonance energy transfer (TR-FRET) signals were measured 1 hour later at room temperature. Test compound potency was assessed at 10 serially diluted concentrations.

Assay: TR-FRET Assay for BIR2 and BIR3: Ten nanomolar of 6× Histidine-tagged BIR2 domain, corresponding to amino acids 124-240 of XIAP, or BIR3 domain, corresponding to amino acids 241-356 of XIAP, was mixed with 20 nM of the peptide AVPIAQKSEK-(c-biotin)-OH 1:2 TFA, in the presence of 50 mM Tris-Cl, pH 7.5, 100 mM NaCl, 1 mM dithiothreitol (DTT) and 0.1 mg/mL bovine serum albumin (BSA). Following a 45 min. incubation at 37° C., Europium-Streptavidin and Allophycocyanin conjugated anti-Histidine antibody were added to a final concentration of 1.5 nM and 15 nM, respectively. Time-resolved fluorescence resonance energy transfer (TR-FRET) signals were measured 1 hour later at room temperature. Test compound potency was assessed at 10 serially diluted concentrations. Percentage of inhibition at each concentration was determined to generate an IC50 value for each test compound.

Assay: TR-FRET Assay: The peptide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA ("Peptide A") was identified as a substrate for the TR-FRET assay by screening the 6× Histidine-tagged BIR2 domain and BIR3 domain of XIAP against a set of 29 peptides synthesized based on sequences reported by Sweeny et al. (Biochemistry, 2006, 45, 14740 14748). The peptides were labeled with the fluorescent tags FITC or TAMRA and Kd values were determined by fluorescence polarization assay. The sequence AVPIAQKSEK was identified as optimal for using in an assay. The peptide sequence was derivatized with biotin to provide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA as the substrate for the TR-FRET assay.
