Supra-sensitivity: Dynamic nuclear polarization (DNP) enhanced solid-state NMR spectroscopy was performed on self-assembled peptide nanotubes. This approach yields significant experimental time savings (about five orders of magnitude; see picture) and was
Biomimetic protecting-group-free 2′, 3′-selective aminoacylation of nucleosides and nucleotides

Aminoacyl phosphate monoesters can be prepared free of an amino-protecting group and used directly in lanthanum-promoted selective monoacylation of either the 2′ or 3′-hydroxyl of nucleosides and nucleotides. For example, phenylalanyl ethyl phosphate rapi

The reaction of amino acids and phosphorus trichloride in THF was studied by 31P NMR tracing and ESI-MS/MS. A series of hydridophoranes and cyclic dipeptides were obtained. The reaction presented interesting diversity and the reaction mechanism was proposed. The mechanism suggests that phosphorus plays an important role in the synthesis of amino acid hydridophorane and cyclic dipeptides. The results also show that 31P NMR and ESI-MS/MS are useful tools for the investigation of reaction mechanism. Copyright
A SYNTHETIC CYCLIC DIPEPTIDE AND A PROCESS THEREOF

Page/Page column 16, (2011/06/11)
The disclosure relates to preparation and self-assembly of aromatic cyclic dipeptide into one and two dimensional nano, meso and micro structures. The said structures of cyclic dipeptide can be electrospinned into threads, fabrics, suture, bandage materials. They are also useful in cell culturing, tissue culturing, drug delivery system, as composite materials, as inhibitors of fibrillization and in Biomedical research such as neurological regeneration and organ replacement studies.

Emeheterone, a fungal metabolite, was synthesized from DL-phenylalanine.Based on the results of this synthesis, the structure of emeheterone was redetermined as 3,6-dibenzyl-2-hydroxy-5-methoxypyrazine 4-oxide.
Pyrazine Chemistry. II. Reduction of 3,6-Dibenzylidenepiperazine-2,5-diones
