  Unique Overlap in the Prerequisites for Thrombin Inhibition and Oral Bioavailability Resulting in Potent Oral Antithrombotics

  摘要：

  Despite intense research over the last 10 years, aided by the availability of X-ray structures of enzyme-inhibitor complexes, only very few truly orally active thrombin inhibitors have been found. We conducted a comprehensive study starting with peptide transition state analogues (TSA). Both hydrophobic nonpeptide analogues as well as hydrophilic peptidic analogues were synthesized. The bioavailability in rats and dogs could be drastically altered depending on the overall charge distribution in the molecule. Compound 27, a tripeptide TSA inhibitor of thrombin, showed an oral bioavailability of 32% in rats and 71% in dogs, elimination half-lives being 58 and 108 min, respectively. The thrombin inhibition constant of compound 27 was 1.1 nM, and in an in vivo arterial flow model, the ED50 was 5.4 nmol/kg(.)min, comparable to known non-TSA inhibitors. A molecular design was found that combines antithrombotic efficiency with oral bioavailability at low dosages.

• Peptide Fragment Coupling Using a Continuous-Flow Photochemical Rearrangement of Nitrones
  作者：Yuan Zhang、Melissa L. Blackman、Andrew B. Leduc、Timothy F. Jamison

  DOI：10.1002/anie.201300504

  日期：2013.4.8

  amide bond formation by way of a continuous‐flow photochemical rearrangement of nitrones was described (see scheme). Simple aryl‐alkyl amide bonds as well as complex peptide bonds were constructed efficiently with a residence time less than 20 minutes. A tetrapeptide was synthesized in this way and the method could be applied to peptide fragment coupling.

• Studies on N-deprotection of ψ(CH₂NH) pseudodipeptide methyl esters. Cyclization to 2-ketopiperazines

  日期：——

  N-Deprotection of Z- and Boc-aminomethylene pseudodipeptide methyl esters yielded not only the expected linear deprotected compounds but also the 2-ketopiperazine cyclic analogues. The extent of lactamization was found to be dependent on the nature of the amino acid, the sequence order, and the deprotection conditions. Hydrogenation of Z-pseudodipeptides containing N-terminal basic amino acids in acidic media afforded linear compounds, while replacement of these basic residues by Leu gave mixtures of linear and cyclic pseudodipeptides. The reverse-sequence analogues, with Lys or Arg at the C-terminus, yielded the corresponding 2-ketopiperazines as the only reaction products. Opposite results were obtained for C-terminal Leu derivatives in which almost no cyclization occurred. Hydrogenation under neutral conditions gave mainly cyclic derivatives, while linear analogues were predominant after treatment of Boc-protected pseudodipeptides with trifluoroacetic acid or HCl.
