A Fluorescent Chemical Sensor for Biological Amines

摘要

The invention is provides for a variety of fluorescence sensing compounds characterized generally as having a coumarin-3-aldehyde scaffold with a pendant aryl moiety at the C4-position of the scaffold. The further provides a method for detecting primary amines in a biological sample using said compounds. Especially, for the selective labeling and imaging of catecholamines in live and fixed secretory cells.
