The synthesis of aminodeoxybestatin and epi-aminodeoxybestatin [(2S,3R)- and (2R,3R)-2,3-di-amino-4-phenylbutanoyl-L-leucine; (2S,3R)- and (2R,3R)-DAPBA-L-Leu)], bestatin and epi-bestatin analogues, respectively, in which the hydroxy group has been replaced with an amino group, is described by two different methods. The first one involves the synthesis of bis-(N-Z)-DAPBA, by homologation of N-Z-phenylalanine, via a modified Strecker synthesis followed by subsequent coupling with the methyl…

From amino acids to heteroaromatics--thiopeptide antibiotics, nature's heterocyclic peptides.
TLDR
This Review shows how organic chemists have developed innovative methods for the synthesis of the heterocyclic ring systems, including routes inspired by the likely biosynthetic processes, and successfully assembled such building blocks into the final target molecule by application of orthogonal protecting groups and coupling methodologies.
A new and versatile procedure for the incorporation of α,β-diamino acids into peptides
A new route to peptide segments incorporating α,β-diamino acids either at the α- or β-positions is provided by enzymeimimetic ring opening of 3-amino β-lactams with α-amino acid esters promoted by
A Novel Method for the Asymmetric Synthesis of α,β-Diamino Acids by a Glucose-Mediated Stereoselective Strecker Reaction
A novel method for the asymmetric synthesis of α,β-diamino acids by using the 2,3,4,6-tetra-O-pivaloyl-β-D-glucopyranosyl group (Piv4Glc) as chiral auxiliary was developed (Table and Scheme). The

Synthesis of sulfur-containing analogues of bestatin. Inhibition of aminopeptidases by alpha-thiolbestatin analogues.
TLDR
The results suggest that the sulfur atoms in 2-thiolbestatin and bestatin thioamide do not interact strongly with the active-site zinc atom of these aminopeptidases when the inhibitors are bound to the enzyme.
alpha,alpha-Difluoro-beta-aminodeoxystatine-containing renin inhibitory peptides.
TLDR
Angiotensinogen analogues VII and VIII that contain these novel amino analogues of difluorostatine were shown to be inhibitors of the enzyme renin.
Synthesis and structure-activity relationships of bestatin analogues, inhibitors of aminopeptidase B.
TLDR
In a series of compounds in which the L-leucine residue of bestatin was substituted with other amino acids, only the one containing isoleucine showed more activity than bestatin, and the p-Methyl-, p-chloro-, and p-nitrobestatins showed greater activity.
Inhibition of arginine aminopeptidase by bestatin and arphamenine analogues. Evidence for a new mode of binding to aminopeptidases.
TLDR
Analysis of the synthesis and inhibition kinetics of a new, potent inhibitor of arginine aminopeptidase and structure-activity data for a series of ketomethylene dipeptide isosteres show that the S1 and S1' subsites preferentially bind basic and aromatic side chains, respectively.

Leucine aminopeptidase: bestatin inhibition and a model for enzyme-catalyzed peptide hydrolysis.
TLDR
The three-dimensional structures of native bovine lens leucine aminopeptidase and its complex with bestatin, a slow-binding inhibitor, have been solved and exhaustively refined and features of a mechanism of catalysis of peptide hydrolysis by leucinescence by bestatin are discussed.
