  Incorporation of Non-natural Amino Acids Improves Cell Permeability and Potency of Specific Inhibitors of Proteasome Trypsin-like Sites

  摘要：

  Proteasomes degrade the majority of proteins in mammalian cells by a concerted action of three distinct pairs of active sites. The chymotrypsin-like sites are targets of antimyeloma agents bortezomib and carfilzomib. Inhibitors of the trypsin-like site sensitize multiple myeloma cells to these agents. Here we describe systematic effort to develop inhibitors with improved potency and cell permeability, yielding azido-Phe-Leu-Leu-4-aminomethyl-Phe-methyl vinyl sulfone (4a, LU-102), and a fluorescent activity-based probe for this site. X-ray structures of 4a and related inhibitors complexed with yeast proteasomes revealed the structural basis for specificity. Nontoxic to myeloma cells when used as a single agent, 4a sensitized them to bortezomib and carfilzomib. This sensitizing effect was much stronger than the synergistic effects of histone acetylase inhibitors or additive effects of doxorubicin and dexamethasone, raising the possibility that cornbinations of inhibitors of the trypsin-like site with bortezomib or carfilzomib would have stronger antincoplastic activity than combinations currently used clinically.

  The present invention is an inhibitor of the trypsin-like β2/β2i sites of the proteasome. The inhibitor is characterized as being a peptide-based epoxyketone or vinyl sulfone that contains an arginine or 4-aminomethylene-L-phenylalanine at the C-terminus (i.e., at the P1 position). Methods for using the inhibitor to inhibit the activity of the β2/β2i site of a proteasome and treat a proteasome-mediated disease or condition are also described.

  本发明是一种抑制蛋白酶体内类似胰蛋白酶的β2/β2i位点的抑制剂。该抑制剂的特征是含有精氨酸或4-氨基甲基-L-苯丙氨酸在C-末端（即在P1位点）的基于肽的环氧酮或乙烯基磺酰。本发明还描述了使用该抑制剂来抑制蛋白酶体的β2/β2i位点活性和治疗蛋白酶体介导的疾病或症状的方法。
