Design and synthesis of macrocyclic peptidyl hydroxamates as peptide deformylase inhibitors
摘要:
Macrocyclic peptidyl hydroxamates were designed, synthesized, and evaluated as peptide deformylase (PDF) inhibitors. The most potent compound exhibited tight, slow-binding inhibition of Escherichia coli PDF (K(I)* = 4.4 nM) and had potent antibacterial activity against Gram-positive bacterium Bacillus subtilis (MIC = 2-4 mu g/mL).

target for antibacterial drug design. We have previously reported an N-formylhydroxylamine-based, metal-chelating macrocyclic PDF inhibitor, in which the P(1)' and P(3)' side chains are covalently joined. In this work, we have carried out a structure-activity relationship study on the size of the macrocycle and found that 15-17-membered macrocycles are optimal for binding to the PDF active site.

Cobalt porphyrin catalysed intramolecular ring-closing C-H bond amination enables direct synthesis of various N-heterocycles from aliphatic azides. Pyrrolidines, oxazolidines imidazolidines, isoindolines and tetrahydroisoquinoline can be obtained in good to excellent yields in a single reaction step with an air and moisture stable catalyst. Kinetic studies of the reaction in combination with DFT calculations

challenging intramolecular direct C(sp3)–H amination of unactivated organic azides to generate a range of saturated N-heterocycles with the highest turnover number (TON) (1 mol% of 1, 12 h, TON = 62; 0.1 mol% of 1, 7 days, TON = 620) reported to date. The catalyst is easily recycled without noticeable loss of catalytic activity. A detailed kinetic study for C(sp3)–H amination of 1-azido-4-phenylbutane (S1) revealed
Synthesis of medium- and large-sized cyclic amines using alkylation with 2-nitrobenzenesulfonamides is described. Using either conventional alkylation procedures or Mitsunobu conditions, the cyclization reaction proceeded in a highly efficient manner. The usefulness of this methodology has been fully demonstrated in the total synthesis of lipogrammistin-A (9), an 18-membered cyclic polyamine. (C) 2002 Published by Elsevier Science Ltd.
