Capzimin (3027) shows 80-fold selectivity for Rpn11 over Csn5, 10-fold over AMSH and 6-fold over BRCC36 (IC50=30 μM, 4.5 μM and 2.3 μM respectively. Capzimin is screened against the NCI panel of 60 cancer cell lines. The median GI50 is 3.3 μM. Capzimin exhibits promising activity in leukemia cells including the SR and K562 cell lines (GI50 values of 0.67 μM and 1 μM respectively), as well as several solid tumor cell lines including NCI-H460 (non-small cell lung cancer; GI50= 0.7 μM) and MCF7 (breast cancer; GI50=1.0 μM). Immunoblotting for the processed form of caspase 3 and caspase-cleaved poly ADP-ribose polymerase in HCT116 cells confirm that Capzimin not only blocks cell growth, but also induces apoptosis[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol
Fluorescence polarization assays are performed in low-volume 384 well solid black plates in quadruplicate. The assays are performed in buffer containing 50 mM Tris-HCl pH7.5, 1mM MgCl2, 50 μM ATP, 1 mM DTT and 0.01% NP-40. The components for the assay are added in the follow sequence: 1) 5 μL compound (Capzimin, et al.) (in 3% DMSO) at different concentrations, 2) 5 μL of diluted human 26S proteasome, and 3) 5μL of substrate (3 nM Ub4- peptideOG). 100 μM Zn(cyclen)2+ is present in the titration reaction for the experiments performed with Zn(cyclen)2+. Fluorescence polarization is measured at 30°C with excitation at 480 nm and emission at 520 nm. Collected data is normalized to DMSO control and fitted to a dose-response curve to determine the IC50 value[1].

HCT116 cells are treated with different concentrations of 3021 or Capzimin for 72 hours in normal or low serum medium and then mixed with CellTiter-Glo reagent to estimate cell proliferation. Measured luminescence values are normalized to DMSO control and data are fitted to a dose-response equation to determine the GI50[1].
