Assay: AlphaScreen Assay: The following example describes an assay that measured the ability of compounds to inhibit the binding of p53 to MDM2 using the AlphaScreen assay technology (PerkinElmer). The following protocol is an adaptation of the method described by H. R. Lawrence et al. (Bioorg. Med. Chem. Lett. 19 (2009) 3756-3759). Recombinant, truncated, human, N-terminal GST-MDM2 (aa 1-150) was obtained from GeneScript. Wild-type, full length human N-terminal 6-his p53 was purchased from SignalChem.Resulting in a final reaction volume of 24 μl PBS, 0.1% Tween-20, and 10% glycerol, 30 ng of MDM2 was added, followed by the addition of 10 of compound diluted in 100% DMSO that provided a final DMSO concentration of 4%. 30 ng of p53 was then added, mixed, and incubated at room temperature for 1 hour. Glutathione donor beads and Nickel acceptor beads (0.5 μg each; PerkinElmer) were added under subdued lighting conditions to a final reaction volume of 30 μl/well in a 96 well, ½ volume Proxima plate.

Assay: AlphaScreen Assay: The following example describes an assay that measured the ability of compounds to inhibit the binding of p53 to MDM2 using the AlphaScreen assay technology (PerkinElmer). The following protocol is an adaptation of the method described by H. R. Lawrence et al. (Bioorg. Med. Chem. Lett. 19 (2009) 3756-3759). Recombinant, truncated, human, N-terminal GST-MDM2 (aa 1-150) was obtained from GeneScript. Wild-type, full length human N-terminal 6-his p53 was purchased from SignalChem.Resulting in a final reaction volume of 24 μl PBS, 0.1% Tween-20, and 10% glycerol, 30 ng of MDM2 was added, followed by the addition of 10 of compound diluted in 100% DMSO that provided a final DMSO concentration of 4%. 30 ng of p53 was then added, mixed, and incubated at room temperature for 1 hour. Glutathione donor beads and Nickel acceptor beads (0.5 μg each; PerkinElmer) were added under subdued lighting conditions to a final reaction volume of 30 μl/well in a 96 well, ½ volume Proxima plate.

Assay: HTRF Biochemical Assay: Among the advantages of this Abeta 42 HTRF gamma-secretase assay is the construction of the biotinylated, recombinant CT6-I45F substrate, which has provided a highly active substrate allowing for increased sensitivity and detection of gamma-secretase activity. This recombinant protein is based on the sequence of APP, but has a truncation that removes an auto-inhibitory domain. This provides markedly increased activity. Furthermore, an AviTag site has been cloned into the vector encoding this substrate. Consequently, overproduction of the CT6-I45F substrate in the presence of biotin ligase and biotin results in direct biotinylation of our substrate. This novel approach further increases the sensitivity of the assay. Other attempts at development of a high throughput gamma-secretase assay that screens for Abeta 42 have been unsuccessful. This is the first successful development of a biochemical assay that screens for gamma-secretase cleavage at the Abeta 42-site.

Assay: Inhibition Assay: To determine their in vitro action on human PDE 5, the test substances are dissolved in 100% DMSO and serially diluted. Typically, dilution series (1:3) from 200 uM to 0.091 uM are prepared (resulting final concentrations in the test: 4 uM to 0.0018 uM). In each case 2 ul of the diluted substance solutions are placed into the wells of microtitre plates (Isoplate-96/200 W; Perkin Elmer). Subsequently, 50 ul of a dilution of the above-described PDE 5 preparation are added. The dilution of the PDE 5 preparation is selected such that, during the later incubation, less than 70% of the substrate is converted (typical dilution: 1:100; dilution buffer: 50 mM tris/hydrochloric acid pH 7.5, 8.3 mM magnesium chloride, 1.7 mM EDTA, 0.2% BSA). The substrate, [8-3H]cyclic guanosine-3',5'-monophosphate (1 uCi/ul; Perkin Elmer) is diluted 1:2000 with assay buffer (50 mM tris/hydrochloric acid pH 7.5, 8.3 mM magnesium chloride, 1.7 mM EDTA).

Assay: Inhibition Assay: To determine their in vitro action on human PDE 5, the test substances are dissolved in 100% DMSO and serially diluted. Typically, dilution series (1:3) from 200 uM to 0.091 uM are prepared (resulting final concentrations in the test: 4 uM to 0.0018 uM). In each case 2 ul of the diluted substance solutions are placed into the wells of microtitre plates (Isoplate-96/200 W; Perkin Elmer). Subsequently, 50 ul of a dilution of the above-described PDE 5 preparation are added. The dilution of the PDE 5 preparation is selected such that, during the later incubation, less than 70% of the substrate is converted (typical dilution: 1:100; dilution buffer: 50 mM tris/hydrochloric acid pH 7.5, 8.3 mM magnesium chloride, 1.7 mM EDTA, 0.2% BSA).
