The present invention provides a compound represented by the following formula (I), a pharmaceutically acceptable salt thereof, or a solvate thereof.
wherein:
R
1
and R
2
are each separately selected from the group consisting of hydrogen, alkyl, alkenyl, acyl, and hydroxyalkyl;
R
3
is hydrogen or halogen;
ring A is a benzene ring or a pyridine ring;
ring B is selected from the group consisting of the following formulas (i), (ii), (iii), and (iv):
in the formula (ii), R
a
is alkyl;
R
4
and R
5
are each separately selected from the group consisting of hydrogen, hydroxy, alkoxy, haloalkoxy, halohydroxyalkoxy, and aminoalkyl; and
[Formula 3]
represents a double bond or a triple bond. The above compound can be used as a molecular probe for imaging tau proteins that accumulate in the brain.
