Inhibition of the Human Proteasome by Imidazoline Scaffolds
The
proteasome has emerged as the primary target for the treatment
of multiple myeloma. Unfortunately, nearly all patients develop resistance
to competitive-type proteasome inhibitors such as bortezomib. Herein,
we describe the optimization of noncompetitive proteasome inhibitors
to yield derivatives that exhibit nanomolar potency (compound <b>49</b>, IC<sub>50</sub> 130 nM) toward proteasome inhibition and
overcome bortezomib resistance. These studies illustrate the feasibility
of the development of noncompetitive proteasome inhibitors as additives
and/or alternatives to competitive proteasome inhibitors
