β-Keto and β-hydroxyphosphonate analogs of biotin-5′-AMP are inhibitors of holocarboxylase synthetase

Holocarboxylase synthetase (HLCS) catalyzes the covalent attachment of biotin to cytoplasmic and mitochondrial carboxylases, nuclear histones, and over a hundred human proteins. Nonhydrolyzable ketophosphonate (β-ketoP) and hydroxyphosphonate (β-hydroxyP) analogs of biotin-5′-AMP inhibit holocarboxylase synthetase (HLCS) with IC50 values of 39.7 μM and 203.7 μM. By comparison, an IC50 value of 7 μM was observed with the previously reported biotinol-5′-AMP. The Ki values, 3.4 μM and 17.3 μM, respectively, are consistent with the IC50 results, and close to the Ki obtained for biotinol-5′-AMP (7 μM). The β-ketoP and β-hydroxyP molecules are competitive inhibitors of HLCS while biotinol-5′-AMP inhibited HLCS by a mixed mechanism.

BIOPROBES FOR LYSYL OXIDASES AND USES THEREOF

The present invention relates to novel bioprobes which are capable of binding to certain amine oxidase enzymes. These bioprobes are useful in methods of detecting and determining the concentration of certain amine oxidase enzymes in a sample as well as in methods for the quantitative assessment of inhibition of certain amine oxidases.

Site-Selective Modification of Peptides and Proteins via Interception of Free-Radical-Mediated Dechalcogenation

The development of site-selective chemistry targeting the canonical amino acids enables the controlled installation of desired functionalities into native peptides and proteins. Such techniques facilitate the development of polypeptide conjugates to advance therapeutics, diagnostics, and fundamental science. We report a versatile and selective method to functionalize peptides and proteins through free-radical-mediated dechalcogenation. By exploiting phosphine-induced homolysis of the C?Se and C?S bonds of selenocysteine and cysteine, respectively, we demonstrate the site-selective installation of groups appended to a persistent radical trap. The reaction is rapid, operationally simple, and chemoselective. The resulting aminooxy linker is stable under a variety of conditions and selectively cleavable in the presence of a low-oxidation-state transition metal. We have explored the full scope of this reaction using complex peptide systems and a recombinantly expressed protein.
