The present invention provides an α-synuclein aggregate binding agent that has high binding selectivity for an α-synuclein aggregate.
The α-synuclein aggregate binding agent contains a compound represented by a formula (I), a pharmaceutically acceptable salt thereof, or a solvate thereof:
in the formula (I), R1 and R2 are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, acyl, and hydroxyalkyl; R3 is hydrogen or halogen; the ring A is a benzene or pyridine ring; the ring B is represented by the following formula (i) or (ii):
R4 and R5 are each independently selected from the group consisting of hydrogen, hydroxy, alkoxy, haloalkoxy, halohydroxyalkoxy, and aminoalkyl.
