Patent ID: 8772277

Claim:
A compound represented by the formula wherein A is a cyclic group optionally having substituent(s); L a is a bond, —O—, —CO—, —S—, —SO—, —SO 2 —, —NR L1 — or —NR L1 —CO—; L b is a bond or a C 1-3 alkylene group optionally having substituent(s); L c is a bond, —CO—, —O—CO—, —NR L2 —CO—, —SO 2 — or —NR L2 —SO 2 —; R L1 and R L2 are each independently a hydrogen atom, a hydrocarbon group optionally having substituent(s), a heterocyclic group optionally having substituent(s), a hydroxy group optionally having a substituent, an amino group optionally having substituent(s), or an acyl group; ring G is a 4- to 10-membered saturated heterocycle containing one nitrogen atom as a ring-constituting hetero atom, which is optionally bridged and optionally has substituent(s); and E is a group represented by the formula wherein X is —S—, —O— or —NR X —; and R 1 , R 2 and R X are each independently a hydrogen atom, a hydrocarbon group optionally having substituent(s), a heterocyclic group optionally having substituent(s), a hydroxy group optionally having a substituent, an amino group optionally having substituent(s), or an acyl group, or R 1 and R 2 in combination optionally form, together with the adjacent nitrogen atom, a nitrogen-containing heterocycle optionally having substituent(s), or a salt thereof.
