  A Versatile Amino Acid Analogue of the Solvatochromic Fluorophore 4-N,N-Dimethylamino-1,8-naphthalimide: A Powerful Tool for the Study of Dynamic Protein Interactions

  摘要：

  We have developed a new unnatural amino acid based on the solvatochromic fluorophore 4-N,N-dimethylamino-1,8-naphthalimide (4-DMN) for application in the study of protein-protein interactions. The fluorescence quantum yield of this chromophore is highly sensitive to changes in the local solvent environment, demonstrating "switch-like" emission properties characteristic of the dimethylaminophthalimide family of fluorophores. In particular, this new species possesses a number of significant advantages over related fluorophores, including greater chemical stability under a wide range of conditions, a longer wavelength of excitation (408 nm), and improved synthetic accessibility. This amino acid has been prepared as an Fmoc-protected building block and may readily be incorporated into peptides via standard solid-phase peptide synthesis. A series of comparative studies are presented to demonstrate the advantageous properties of the 4-DMN amino acid relative to those of the previously reported 4-N,N-dimethylaminoph-thalimidoalanine and 6-N,N-dimethylamino-2,3-naphthalimidoalanine amino acids. Other commercially available solvatochromic fluorophores are also include in these studies. The potential of this new probe as a tool for the study of protein-protein interactions is demonstrated by introducing it into a peptide that is recognized by calcium-activated calmodulin. The binding interaction between these two components yields an increase in fluorescence emission greater than 900-fold.

  The present invention generally relates to environment-sensitive fluorophores, including environment-sensitive fluorophores for reporting protein/protein and peptide/protein interactions. In one aspect, the present invention is directed to compounds and salts thereof, compositions and methods useful in determining biological interactions. In some cases, the compounds of the present invention are environment-sensitive fluorophores that have spectroscopic behavior that may depend on factors such as the physicochemical properties of the surrounding environment. The compounds of the present invention can be used, in certain embodiments, to monitor ions, small molecules, and biological processes such as protein folding, protein-protein interactions and phosphorylation events.
