  Practical Synthesis of Hydroxamate-Derived Siderophore Components by an Indirect Oxidation Method and Syntheses of a DIG−Siderophore Conjugate and a Biotin−Siderophore Conjugate

  摘要：

  A practical large-scale synthesis of hydroxamate-derived siderophore components (30 and 40) that utilizes an efficient indirect oxidation method is described and applied to the syntheses of nonradioactive labeled siderophores. Oxidation of imines derived from L-ornithine (17) and its tripeptide (19) afforded oxaziridines that were isomerized to stable-nitrones (16 and 18). Acid-catalyzed hydrolysis of nitrones provided hydroxylamines that were converted to the desired hydroxamic acids (30 and 40) suitable for constructing siderophore-drug conjugates (2). The entire synthetic sequence required no chromatographic separation. DIG- and biotin-labeled ferrichrome analogues designed to detect and isolate ferrichrome receptors in various microbes were also synthesized.

  (Z) tripeptide inhibitors of angiotensin-converting enzyme (ACE) was synthesized. The effect of varying the antepenultimate amino acid residue in this series on the biological activity was studied. Introduction of Lys and Orn residues at the P1 position provided the most potent inhibitors, 25a and 25b (IC50: 3.5 and 4.9 x 10(-9) M, respectively), which exhibited an oral antihypertensive activity.

  A series of trans-epoxysuccinyl-peptide derivatives based on the natural inhibitor E-64 were synthesized in the (2R,3R) and (2S,3S) configuration in order to analyze the role of the stereochemistry of this residue in dictating inhibitory potency and selectivity for cysteine proteases. We confirmed that binding of E-64 like trans-epoxysuccinyl compounds is remarkably favored by the (2S,3S) con figuration, but we also found that CA030-type compounds are stronger inhibitors in the (2R,3R) configuration than the related diastereomers. Consequently, the structural requirements for exploiting both the S and S' subsites are not additive and a structure-based design of bis-peptidyl derivatives of trans-epoxysuccinic acid to increase selective inhibition becomes even more difficult. Additional contrasting effects were observed for the pH optima required in the electrostatic interactions at the S and S' subsites. (C) 1997 Elsevier Science Ltd.
