  Development of peptidomimetic boronates as proteasome inhibitors

  摘要：

  Proteasome inhibition has emerged over the past decade as an effective therapeutic approach for the treatment of hematologic malignancies. It is a multicatalytic complex, whose proteolytic activity relies in three types of subunits: chymotrypsin-like (beta 5), trypsin-like (beta 2) and caspase-like (beta 1). Most important for the development of effective antitumor agents is the inhibition of the beta 5 subunits. In this context, the dipeptide boronate bortezomib (Velcade (R)) represents the first proteasome inhibitor approved by the FDA and the lead compound in drug discovery. This paper describes the synthesis and biological evaluation of a series of conformationally constrained pseudopeptide boronates (1-3) structurally related to bortezomib. The synthesized compounds showed a promising inhibitory profile by blocking primarily the chymotrypsin-like activity of the proteasome with K-i values in submicromolar/micromolar range. These compounds also resulted quite selective since no significant inhibition was recorded in the test against bovine pancreatic alpha-chymotrypsin. The obtained results were rationalized by means of docking experiments based on a model of the crystal structure of bortezomib bound to the yeast 20S proteasome providing essential insights for further optimization of this class of inhibitors.

  This paper describes the design, synthesis, and biological evaluation of peptidomimetic boronates as inhibitors of the 20S proteasome, a validated target in the treatment of multiple myeloma. The synthesized compounds showed a good inhibitory profile against the ChT‐L activity of 20S proteasome. Compounds bearing a β‐alanine residue at the P2 position were the most active, that is, 3‐ethylphenylamino
