  Design, Synthesis, Biological Evaluation, and Structure−Activity Relationship (SAR) Discussion of Dipeptidyl Boronate Proteasome Inhibitors, Part I: Comprehensive Understanding of the SAR of α-Amino Acid Boronates

  摘要：

  New series of dipeptidyl boronate inhibitors of 20S proteasome were designed and synthesized, The comprehensive understanding or the SAR was obtained by utilizing the variation of four substituents. From the screened compounds in enzyme, novel inhibitors 49 and 50 were identified to be highly potent druglike candidates with IC50 values of 1.2 and 1.6 nM, respectively, which showed better activities than the drug bortezomib on the market. Two hematologic human tumor cell lines, HL-60 and U266, were significantly sensitive to both candidates and showed nearly the same potency as the standard bortezomib with IC50 values less than 10 nM. But as for most of the eight human solid tumor cell lines, both candidates were more potent than the standard with the IC50 value range of 9.8-70 nM. The activity evaluation of the stereoisomers showed that changing R-isomers to S-isomers greatly reduced the potency and even induced inactivity.

  基于结构的优化和发现 M3258，一种免疫蛋白酶体亚基 LMP7 (β5i) 的特异性抑制剂

  摘要：

  蛋白酶体是泛素依赖性蛋白质降解途径中广泛表达的关键成分，其中包含具有催化活性的亚基（β1、β2 和 β5）。LMP7 (β5i) 是免疫蛋白酶体的一个亚基，是一种主要在造血细胞中表达的诱导型异构体。用于治疗多发性骨髓瘤 (MM) 的临床有效的泛蛋白酶体抑制剂非选择性靶向 LMP7 和组成型蛋白酶体和免疫蛋白酶体的其他亚基，具有相当的效力，这可能会限制这些药物的治疗适用性。在这里，我们描述了新型酰氨基硼酸的发现和基于结构的命中优化，它选择性地抑制 LMP7，同时保留所有其他亚基。对蛋白酶体亚基之间结构差异的开发最终确定了高效能，50 (M3258)。基于 M3258 在 MM 模型中观察到的强大抗肿瘤活性和有利的临床前数据包，在复发/难治性 MM 患者中启动了 I 期临床试验。

  A series of novel dipeptidyl boronic acid proteasome inhibitors composed of beta-amino acids were synthesized, in vitro and in vivo biologically evaluated, and theoretically modeled for the first time. From the screened racemic compounds in enzyme, 4i wits the most active. The IC50 value of its pure enantiomer 4q was 9.6 nM, 36-fold more active than its isomer 4p and as active its the marketed bortezomib in inhibiting human 20S proteasome. This candidate also showed good activities with IC50 values nearly less than 5 mu M against several human solid and hematologic tumor cell lines. Safety evaluation in vivo with zebrafish and Sprague-Dawley (SD) rats showed that the candidate 4q was less toxic than bortezomib. Pharmacokinetic profiles suggested candidate 4q showed a more plasma exposure and longer half-life than bortezomib. Docking results indicated that 4q nearly interacted with 20S proteasome in it similar way as bortezomib.
