"Manipulating Boron and Sugar Acid Interactions for Sensing and Catalysis"
PLEASE NOTE ROOM AND TIME
Abstract: Elevated levels of free sialic acid (FSA) in serum can serve as a marker for certain diseases such as cancer and alcoholism. We have recently developed a fluorescent receptor for FSA that incorporates a unique divergent response mechanism. This dampens the signal of potentially competing ligands such as other monosaccharides. We have now applied this to a receptor for the unique sugar acid KDO found in the LPS of gram negative bacteria. Additionally, we have discovered a remarkably rapid amide bond forming reaction to allow rapid assembly of boron-based sensors.
