Fluorescent nitric oxide donor for the detection and killing of: Pseudomonas aeruginosa

The epidemic of multidrug-resistant bacteria calls for the improvement of both detection methods for bacterial infections and methods of treatment. Nitric oxide is a known potent antibacterial agent, but due to its gaseous and highly reactive nature, it is difficult to incorporate into a stable antibacterial compound. In this paper, we synthesize a nitric oxide donor attached to a fluorescent compound, creating a material that can both detect and kill the deadly multi-drug resistant bacteria strain Pseudomonas aeruginosa. Detection occurs through a bacterial enzyme-activated color change, showing a clear and obvious change from blue to yellow under UV light. The synthesized compound spontaneously releases 853 μmol of nitric oxide/g from a 10 mM initial concentration. Antibacterial efficacy studies after exposing Pseudomonas aeruginosa to a 10 mM dose of the synthesized compound show a 55-75% reduction in bacteria after 24 hours. This work is the first instance of a small molecule dual-function material that can both detect and kill bacteria.

Improving the fluorescent probe acridonylalanine through a combination of theory and experiment

Acridonylalanine (Acd) is a useful fluorophore for studying proteins by fluorescence spectroscopy, but it can potentially be improved by being made longer wavelength or brighter. Here, we report the synthesis of Acd core derivatives and their photophysical characterization. We also performed ab initio calculations of the absorption and emission spectra of Acd derivatives, which agree well with experimental measurements. The amino acid aminoacridonylalanine (Aad) was synthesized in forms appropriate for genetic incorporation and peptide synthesis. We show that Aad is a superior F?rster resonance energy transfer acceptor to Acd in a peptide cleavage assay and that Aad can be activated by an aminoacyl tRNA synthetase for genetic incorporation. Together, these results show that we can use computation to design enhanced Acd derivatives, which can be used in peptides and proteins.

Nitration of the Acetanilide-type Compounds

Some aromatic compounds containing the imino group (NH) were nitrated in acetic acid or anhydride, and the ortho/para ratios were measured.N-Methyl derivatives of the aforementioned compounds are much less reactive when nitrated under comparable conditions and give significantly lower o/p ratios.These results along with the literature data support the hypothesis that the acetanilide-type compounds are nitrated via N-nitro intermediates.
