BF 227 is a candidate for an amyloid imaging probe for PET, with a Ki of 4.3 nM for Aβ1-42 fibrils.
BF-227 has a high binding affinity for Aβ1-42 fibrils. The Ki value for Aβ1-42 fibrils in competitive binding assay using [125I]BF-180 is 4.3±1.3 nM in BF-227 (Kd value of [125I]BF-180: 10.8±1.5 nM)[1]. [11C]BF-227 is a PET tracer. The AUC for BF-227 (0.994) is much higher than that for FDG (0.839), indicating that BF-227 is more sensitive as well as more specific than FDG in diagnosing AD[2].
