  Synthesis of New (−)-Bestatin-Based Inhibitor Libraries Reveals a Novel Binding Mode in the S1 Pocket of the Essential Malaria M1 Metalloaminopeptidase

  摘要：

  The malarial PfA-M1 metalloaminopeptidase is considered a putative drug target. The natural product dipeptide mimetic, bestatin, is a potent inhibitor of PfA-M1. Herein we present a new, efficient, and high-yielding protocol for the synthesis of bestatin derivatives from natural and unnatural N-Boc-D-amino acids. A diverse library of bestatin derivatives was synthesized with variants at the side chain of either the alpha-hydroxy-beta-amino acid (P1) or the adjacent natural a-amino add (P1'). Surprisingly, we found that extended aromatic side chains at the P1 position resulted in potent inhibition against PfA-M1. To understand these data, we determined the X-ray cocrystal structures of PfA-M1 with two derivatives having either a Tyr(OMe) 15 or Tyr(OBz1) 16 at the 131 position and observed substantial inhibitor-induced rearrangement of the primary loop within the PEA-M1 pocket that interacts with the PI side chain. Our data provide important insights for the rational design of more potent and selective inhibitors of this enzyme that may eventually lead to new therapies for malaria.
