Alzheimer's disease is a neurodegenerative disease with complex and unclear etiology. Amyloid-beta plays an important role in its development and can activate a series of pathological events, leading to brain lesions and death. Therefore, the development of efficient and reliable A beta-specific probes is crucial for the diagnosis and treatment of AD.
Alzheimer's disease (AD) is a neurodegenerative disease. Due to its complex pathological mechanism, its etiology is not yet clear. As one of the main pathological markers of AD, amyloid-beta (A beta) plays an important role in the development of AD. The deposition of A beta is not only related to the degeneration of neurons, but also can activate a series of pathological events, including the activation of astrocytes and microglia, the breakdown of the blood-brain barrier, and the change in microcirculation, which is the main cause of brain lesions and death in AD patients. Therefore, the development of efficient and reliable A beta-specific probes is crucial for the early diagnosis and treatment of AD. This paper focuses on reviewing the application of small-molecule fluorescent probes in A beta imaging in vivo in recent years. These probes efficiently map the presence of A beta in vivo, providing a pathway for the early diagnosis of AD and providing enlightenment for the design of A beta-specific probes in the future.
