  Total Synthesis and Stereochemical Revision of (+)-Aeruginosin 298-A

  摘要：

  [GRAPHICS]Novel routes toward both enantiomers of the bicyclic proline surrogate 2-carboxy-6-hydroxyoctahydroindole, i.e., Choi, were developed on the basis of the oxidative cyclization of L-tyrosine. Synthesis of the proposed sequence of (+)-aeruginosin 298-A did not provide the natural product. Incorporation of a D-leucine residue, in contrast, led to the total synthesis of this thrombin inhibitor.

  A stereoselective synthesis of enantiopure aeruginosin 205B aglycon confirms the presence of a (3R,2S)-3-chloroleucine amide residue and a (6R)-hydroxy (4aR,7aS)-octahydroindole-(2S)-2-carboxamide (Choi) subunit instead of a 6-chloro-substituted core (Ccoi). Enzyme inhibitory tests against thrombin revealed an IC50 of 0.31 μM. The total synthesis of the presumed aeruginosin 205B shows that the α-d-xylopyranosyl

• Structure-based organic synthesis of unnatural aeruginosin hybrids as potent inhibitors of thrombin

  Based on X-ray crystallographic data of complexes of chlorodysinosin A with the enzyme thrombin, a series of analogs were synthesized varying the nature of the P-1, P-2, and P-3 pharmacophoric sites and the central octahydroindole carboxyamide core. In general, introduction of a hydrophobic substituent on the D-leucine amide residue dramatically improved the inhibition of the enzyme. This is rationalized based on a better fit of the P-3 subunit in the hydrophobic S-3 enzyme site. Single digit nanomolar inhibition expressed as IC50 was observed for several analogs.
