  Synthesis, in Vitro and in Vivo Biological Evaluation, Docking Studies, and Structure−Activity Relationship (SAR) Discussion of Dipeptidyl Boronic Acid Proteasome Inhibitors Composed of β-Amino Acids

  摘要：

  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.
