The present invention generally relates to various compounds that are useful as α-synuclein ligands. The invention further relates to methods of using these compounds and their radiolabeled analogs for the detection of synucleinopathies, including Parkinson's disease (PD).
Two new synthetic routes for (E)-N-methyl-2-styryl-4-quinolones have been established, both starting from (E)-2′-cinnamoylaminoacetophenones. In the first, (E)-2′-cinnamoylaminoacetophenones are cyclized and then methylated, while in the second they are methylated followed by in situ cyclization.
