Evaluation of fluorogenic aminonaphthalenesulfonamides and 6-hydrazinobenz[de]isoquinoline-1,3-diones for the detection of bacteria
摘要:
New fluorogenic enzyme substrates were synthesized by the coupling of aminonaphthalenesulfonamides or 6-hydrazinobenz[de]isoquinoline-1,3-diones with beta-alanine. The 6-hydrazinobenz[de]isoquinoline-1,3-diones were also condensed with a range of aryl aldehydes to give the corresponding hydrazones. The photophysical properties of the synthesized amines and hydrazines and their amide, hydrazide and hydrazone derivatives, were examined and they were also incorporated into Columbia agar in order to determine their potential for the detection of pathogenic bacteria.

Biomacromolecules such as proteins are inactivated by hydrophobic ANSA derivatives of the formula:
wherein R
1
and R
2
are hydrophobic or affinity groups and R
3
is selected from the group consisting of aminoacyl groups and peptidyl groups upon nitrosation. ANSA derivatives can be designed to selectively kill tumor cells and various pathogens, including bacteria, viruses, and fungi.
