Site-specific single point mutation by anthranilic acid in hIAPP8-37 enhances anti-amyloidogenic activity

Annulation-Triggered Denitrogenative Transformations of 2-(5-Iodo-1,2,3-triazolyl)benzoic Acids

The ability of [1,2,3]triazolobenzoxazinones to act as a source of "hidden" diazo group was discovered. These diazo precursors can be easily prepared by the intramolecular cyclization of 2-(5-iodo-1,2,3-triazolyl)benzoic acids. The Cu-catalyzed capture of the hidden diazo group allows for further functionalization through the denitrogenative pathway. The transformations proceed via the formation of either diazoimine or diazoamide intermediates. Novel routes to various anthranilamides as well as thiolated benzoxazinones were developed using the one-pot cyclization/diazo capture procedure.

Versatility in Self-assembly and Morphology of Non-Coded Anthranilic acid and Phenylglycine based Dipeptide Stereoisomers

Beauty in the self-assembly patterns of isomeric dipeptides of Boc-Ant-L-Phg-OMe (1) bearing two rigid, unnatural amino acids (Ant: Anthranilic acid, Phg: Phenylglycine) is demonstrated. Additionally, self-assembly and morphological variation by...
