(wherein, R
1
and R
2
are the same or different and each represents a hydrogen atom, hydrocarbon group or heterocyclic group, or R
1
and R
2
may form, together with the adjacent carbon atom, a 3-8 membered iso- or heterocyclic group, R
3
represents a cyclic group, a hydroxy group, a mercapto group that may have oxo, or an amino group, R
4
represents a hydrogen atom, a hydrocarbon group, a hydroxy group, a mercapto group which may have oxo, or an amino group, or R
2
and R
4
may link together to form a double bond, X represents a bond or a linear hydrocarbon group, W represents an oxygen atom or a sulfur atom, ring B represents a 5-8 membered nitrogen-containing heterocyclic group, ring C represents a benzene ring, and
represents a single bond or a double bond), or a salt or a prodrug thereof that has excellent neurodegenerative inhibitory activity and brain penetrability, and is useful as an agent for preventing/treating neurodegenerative diseases.
