摘要

To expand the scope of D-pi-A based near-infrared (NIR) probes for detecting beta-amyloid (A beta) plaques and to systematically explore the relationship among their structural characteristics, optical properties, and biological properties, three series of smart NLR. probes with different aromatic rings and up to seven trans double bonds were synthesized and evaluated. Marked correlations between the conjugated pi system and properties of these probes, such as optical data, binding ability, and brain uptake, were observed. One probe, PHC-4, displayed improved properties as a NIR probe for the in vivo detection of A beta plaques.
