wherein Ar is a cyclic group optionally having substituent(s); X is a bond or a spacer having a main chain of 1 to 6 atoms;
R
1
and R
2
are the same or different and each is a hydrogen atom or a hydrocarbon group optionally having substituent(s), or R
1
and R
2
may form, together with the adjacent nitrogen atom, a nitrogen-containing heterocycle optionally having substituent(s); Y is a divalent hydrocarbon group optionally having substituent(s) (except CO);
R
3
is a hydrogen atom or a hydrocarbon group optionally having substituent(s); and ring A and ring B
may further have substituents, and when ring B further has a substituent, the substituent may be linked to R
1
to form a ring, or a salt thereof, or a prodrug thereof, is provided.
