  Exploring the chiral space within the active site of α-thrombin with a constrained mimic of d -Phe-Pro-Arg — design, synthesis, inhibitory activity, and X-ray structure of an enzyme–inhibitor complex

  摘要：

  An indolizidinone motif with strategically placed substitutents was designed and synthesized as a constrained mimic of D-Phe-Pro-Arg. Low nanomolar inhibition of a-thrombin validates the design elements in this inhibitor which also exhibits a 20-fold selectivity for thrombin versus trypsin. An X-ray crystal structure of the inhibitor with alpha-thrombin shows the expected interactions with key amino acids within the active site and some notable changes in positions.

  A versatile synthesis of a β-turn peptidomimetic scaffold: An approach towards a designed model antagonist of the tachykinin NK-2 receptor

  摘要：

  A general and stereocontrolled synthesis of an azabicyclo[4.3.0] nonane amino acid template with an appended substitutent at C-5 was developed The approach allows for stereochemical and functional variations that extend the utility of these rigid amino acid motifs as peptidomimetics. The synthesis of a weakly active but specific NK-2 receptor antagonist is described. Copyright (C) 1996 Elsevier Science Ltd

  The hydroxymethyl-substituted indolizidines 6 and 7, representative members of a ring-B-expanded alexine- australine subclass, are readily accessible by starting with furan-based silyloxydiene 12 and hydroxymethyl hemiaminal 11, through a synthesis sequence involving a scantily exploited vinylogous version of the Mannich reaction. The key iminium electrophilic acceptor 11 is, in turn, available through a vinylogous intermolecular Mukaiyama aldolization process between pyrrole-based silyloxydiene 8 and (S)-glyceraldehyde 9.
