THK5351
CAS No. : 1707147-26-9
MCE 国际站：THK5351
产品活性：THK5351被放射性标记后可作为放射性示踪剂，用于研究大脑中tau病理成像。
研究领域：Neuronal Signaling
作用靶点：Tau Protein
In Vitro: Aggregated tau protein is a major neuropathological substrate central to the pathophysiology of neurodegenerative diseases such as Alzheimer's disease (AD). 18F-THK5351 binds to Alzheimer disease hippocampal homogenates with high affinity (Kd=2.9 nM; maximum number of binding sites=368.3 pmol/g tissue). It has fast dissociation from white-matter tissue. The THK5351 binding amount correlates with the amount of tau deposits in tissue.
In Vivo: THK5351 exhibits favorable pharmacokinetics and no defluorination in mice. 18F-THK5351 enters the brain immediately after intravenous injection and shows a fast washout from the brain. At 0.1 and 1 mg/kg, no animals died and no treatment-related changes in any animal are noted in clinical observations, body weight measurement, and pathologic examination. Autoradiography in the brain sections of patients with PSP demonstrates [3H]THK-5351 binding to tau deposits with a high selectivity. Although patients with PSP exhibits no remarkable [18F]THK-5351 retention in the temporal cortex, significantly higher tracer retention is observed in the globus pallidus and midbrain.
