It is an object of the present invention to provide a compound inhibiting the binding between ALS-related mutant SOD1 and Derlin-1, a medicament comprising the compound, and a method for treating ALS by administering the medicament to a patient. More specifically, the aforementioned compound is represented by the following formula (1):
wherein X represents a sulfur atom or —CH═CH—; A
1
to A
4
each independently represent a carbon atom or a nitrogen atom, and at least one of A
1
to A
4
is a nitrogen atom; R
1
represents a 1,2,3,4-tetrahydroquinolyl group (or a 3,4-dihydro-1(2H)-quinolyl group), a 3,4-dihydro-4,4-dimethyl-1(2H)-quinolyl group, a 2,3,4,5-tetrahydro-1H-1-benzazepinyl group, or a substituent represented by the following formula (2):
wherein R
4
represents an unsubstituted or optionally substituted phenyl group, an unsubstituted or optionally substituted pyridyl group, or an unsubstituted or optionally substituted naphthyl group, and R
5
represents any one of a hydrogen atom, a lower alkyl group, a lower alkenyl group, a lower alkynyl group (optionally containing an oxygen atom and/or a double bond), or an unsubstituted or optionally substituted aromatic lower alkyl group; R
2
represents a hydrogen atom, a lower alkyl group, a lower acyl group, or an unsubstituted or optionally substituted aromatic lower alkyl group; and R
3
represents a hydrogen atom, or R
2
and R
3
may bind to each other to form a ring.
