BF-170是一种选择性的tau纤维结合剂,其EC50为221 nM。BF-170具有优越的血脑屏障穿透性,在小鼠静脉注射后2分钟脑组织中的浓度达到9.1% ID g(在30分钟后,脑内清除率为0.25% ID g),可作为阿尔茨海默病(AD)中tau蛋白病理成像的探针。在阿尔茨海默病早期阶段研究中,BF-170具有关键作用,并有潜力用于tau相关神经退行性疾病的成像研究。
The metallo-protein Cu/Zn-superoxide dismutase (SOD1) is a ubiquitous enzyme responsible for scavenging superoxide radicals. Mutations in SOD1, which alter its metal binding capacity and can result in protein misfolding and aggregation, have been linked to familial amyotrophic lateral sclerosis (ALS). Cu-ATSM is an orally bioavailable, blood-brain barrier permeable complex that has traditionally been used in cellular imaging experiments to selectively label hypoxic tissue via its susceptibility to reduction by oxygen-depleted mitochondria. More recently, Cu-ATSM has been reported to improve locomotor function and survival in a transgenic ALS mouse model by delivering copper specifically to cells in the spinal cords of mice producing misfolded SOD1 proteins. Copper chaperone for SOD (CCS) is presumed to utilize the copper from Cu-ATSM to prevent misfolding of the SOD1 protein.
Gadobutrol is a medicinal product used in diagnostic magnetic resonance imaging (MRI) in adults and children. It provides contrast enhancement during cranial, spinal, breast, or other investigations. In the central nervous system, Gadobutrol works by high
