Rational design of a high-affinity fluorescent probe for visualizing monitoring the amyloid β clearance effect of anti-Alzheimer's disease drug candidates

Beta-amyloid (Aβ), the most pivotal pathological hallmark for Alzheimer's disease (AD) diagnosis and drug evaluation, was recognized by TZ095, a high-affinity fluorescent probe developed by rational molecular design. With a TICT mechanism, TZ095 exhibited remarkable affinity with Aβ aggregates (K
