Synthesis and pharmacological evaluation of [18F]PBR316: a novel PET ligand targeting the translocator protein 18 kDa (TSPO) with low binding sensitivity to human single nucleotide polymorphism rs6971
RSC Medicinal Chemistry(2021)
摘要
PBR316 has high brain uptake, biodistribution consistent with TSPO expression and is insensitive to rs6971 polymorphism with a LAB:HAB ratio of 1.5. It can be prepared in >99% radiochemical purity, 160–400 GBq μmol−1 and >98.5% stability after 4 h.
