- The biosynthesis of the 3,4-dihydroxybenzoate (3,4-DHB) moieties of the siderophore petrobactin, produced by B. anthracis str. Sterne, was probed by isotopic feeding expts. in Fe-deficient media with a mixt. of unlabeled...
- Synthesis and conformational analysis of a cyclic peptide obtained via i to i+4 intramolecular side-chain to side-chain azide-alkyne 1,3-dipolar cycloaddition.
[作者:Cantel, Sonia;Le Chevalier Isaad, Alexandra;Scrima, Mario;Levy, Jay J.;DiMarchi, Richard D.;Rovero, Paolo;Halperin, Jose A.;D'Ursi, Anna Maria;Papini, Anna Maria;Chorev, Michael;,期刊:Journal of Organic Chemistry, 页码:5663-5674 , 文章类型: 研究论文,,卷期:2008年73-15]
- Intramol. side-chain to side-chain cyclization is an established approach to achieve stabilization of specific conformations and a recognized strategy to improve resistance toward proteolytic degrdn. To this end, cycliza...
