《Design of a multivalent bifunctional chelator for diagnostic 64Cu PET imaging in Alzheimer′s disease》 was published in Proceedings of the National Academy of Sciences of the United States of America in 2020. These research results belong to Cho, Hong-Jun; Huynh, Truc T.; Rogers, Buck E.; Mirica, Liviu M.. Product Details of 139115-91-6 The article mentions the following:
Herein, we report a 64Cu positron emission tomog. (PET) imaging agent that shows appreciable in vivo brain uptake and exhibits high specific affinity for beta-amyloid (Aβ) aggregates, leading to the successful PET imaging of amyloid plaques in the brains of 5xFAD mice vs. those of wild-type mice. The employed approach uses a bifunctional chelator with two Aβ-interacting fragments that dramatically improves the Aβ-binding affinity and lipophilicity for favorable blood-brain barrier penetration, while the use of optimized-length spacers between the Cu-chelating group and the Aβ-interacting fragments further improves the in vivo Aβ-binding specificity and brain uptake of the corresponding 64Cu PET imaging agent. The results came from multiple reactions, including the reaction of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6Product Details of 139115-91-6)
tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6) belongs to ethers.The C-O bonds that comprise simple ethers are strong. Product Details of 139115-91-6 They are unreactive toward all but the strongest bases. Although generally of low chemical reactivity, they are more reactive than alkanes.
