SQ-3

SQ-3, a quinoline analogue, demonstrates moderate selectivity towards α-synuclein aggregates (α-syn aggregates) (K i = 39.3 nM) over β-amyloid (Aβ) aggregates (K i = 230 nM) . [18 F]SQ-3 exhibits foundational characteristics as a potential lead compound in developing an effective α-synuclein imaging probe [1].
