  Synthesis of Novel Thrombin Inhibitors. Use of Ring-Closing Metathesis Reactions for Synthesis of P2 Cyclopentene- and Cyclohexenedicarboxylic Acid Derivatives

  摘要：

  The thrombin inhibitory tripeptide D-Phe-Pro-Arg has been mimicked using either cyclopentenedicarboxylic derivatives or a cyclohexenedicarboxylic derivative as surrogate for the P2 proline. In the P3 position, tertiary amides were optimized as D-Phe P3 replacements. The P1 arginine was, in all compounds, substituted with the more rigid and biocompatible 4-amino-methylbenzamidine. One of the novel inhibitors was cocrystallized with a-thrombin and subjected to X-ray analysis. From analysis of the X-ray crystal structure, new ligands were designed leading to significantly improved binding affinity, the lead candidate exhibiting an in vitro IC50 of 49 nM.

  New Proline Mimetics:  Synthesis of Thrombin Inhibitors Incorporating Cyclopentane- and Cyclopentenedicarboxylic Acid Templates in the P2 Position. Binding Conformation Investigated by X-ray Crystallography

  摘要：

  With the aim to prepare nonpeptidic thrombin inhibitors, the amino acids of the thrombin-inhibiting tripeptide chain D-Phe-Pro-Arg were replaced with isosteres. Arg was replaced with the more rigid P1 truncated p-amidinobenzylamine (Pab), Pro with either cyclopentane-1,2-dicarboxylic acid or cyclopentene-1,5-dicarboxylic acid, and D-Phe with a series of readily available lipophilic amines. One of the most potent compounds (25, pIC(50) = 6.01) in these series was cocrystallized with thrombin where the X-ray crystal structure provide insight to the structure-activity relationship (SAR).

  With the aim to replace the natural amino acid proline by a proline mimetic structure, a cyclopent-2-enecarbonyl moiety was studied at the P2 position of prolyl oligopeptidase (POP) inhibitors. The cyclopent-2-enecarbonyl moiety proved to be an excellent proline mimetic at the P2 position of POP inhibitors. The replacement is particularly useful when increased lipophilicity is needed.
