The design of novel and functional biomimetic foldamers remains a major challenge in creating mimics of native protein structures. Herein, we report the stabilization of a remarkably short β-sheet by incorporating N-(hydroxy)glycine (Hyg) residues into the backbone of peptides. These peptide- peptoid hybrids form unique parallel β-sheet structures by selfassembly upon hydrogenation. Our spectroscopic and crystallographic data suggest that the local conformational perturbations induced by N-(hydroxy)amides are outweighed by a network of strong interstrand hydrogen bonds.

A new class of methionine aminopeptidase (MetAP) inhibitors, which contain an internal hydroxamate (N-acyl-N-alkylhydroxylamine) core as the metal-chelating group, has been designed, synthesized, and tested. The compounds exhibited reversible, competitive inhibition against Escherichia coli MetAP as well as human MetAP-1 and MetAP-2. The most potent inhibitor had a Ki value of 2.5 μM and >20-fold selectivity toward E. coli MAP.
Synthesis and antimicrobial properties of cephalosporin derivatives substituted on the C(7) nitrogen with arylmethyloxyimino or arylmethyloxyamino alkanoyl groups

Some 7-aminocephalosporanic acid (7-ACA) derivatives substituted on the C(7) nitrogen with 2-(arylmethyloxyimino)propionyl (3a-f), 2-(arylmethyloxyamino)propionyl (4a-d) and (arylmethyloxyamino)acetyl (2a-d) moieties were synthesized by reaction of the ap
