Ettari et al. recently published the non-covalent amide 6 (Figure 3) that targets β1i- and β5i-subunits of the iCP (Ki values for purified human CPs: 4.9 μM for β1i and 4.4 μM for β5i; Table 1) and inhibits proliferation of a dexamethasone-resistant human multiple myeloma cell line (EC50: 17.8 μM) [88]. The gene discussed is CAD; the disease is AL amyloidosis.
