| | Solid Phase Integrin alphav/beta6 Binding Assay (B-2) |
| Description: | A third series of exemplary compounds was selected for testing in the solid phase integrin αvβ6 binding assay. The compounds tested were compound samples prepared according to procedures described in the Synthetic Examples section, with the stereochemical purity as indicated in the Examples. As in Example B1, microplates were coated with recombinant human integrin αvβ6 (2 μg/mL) in PBS (100 μL/well 25° C., overnight). The coating solution was removed, washed with wash buffer (0.05% Tween 20; 0.5 mM MnCl2; in 1×TBS). The plate was blocked with 200 μL/well of Block Buffer (1% BSA; 5% sucrose; 0.5 mM MnCl2; in 1×TBS) at 37° C. for 2 h. Dilutions of testing compounds and recombinant TGFβ1 LAP (0.67 μg/mL) in binding buffer (0.05% BSA; 2.5% sucrose; 0.5 mM MnCl2; in 1×TBS) were added. The plate was incubated for 2 hours at 25° C., washed, and incubated for 1 hour with Biotin-Anti-hLAP. Bound antibody was detected by peroxidase-conjugated streptavidin. The IC50 values for testing compounds were calculated by a four-parameter logistic regression. |
