Patent ID: 8410089

Claim:
A compound represented by the formula: wherein ring P is a further substituted 6-membered aromatic ring; ring Q is a further optionally substituted 6-membered aromatic ring; A 1 is CR 4a R 4b wherein R 4a and R 4b are each independently a hydrogen atom, an optionally substituted hydrocarbon group, an optionally substituted heterocyclic group or an optionally substituted hydroxy group, NR 4c wherein R 4c is a hydrogen atom or an optionally substituted hydrocarbon group, 0, S, SO or SO 2 ; L 1 is an optionally substituted C 1-5 alkylene group; L 2 is a bond or an optionally substituted C 1-3 alkylene group; L 3 and L 4 are each independently an optionally substituted C 1-3 alkylene group; R 1 is (1) a hydrogen atom, a halogen atom, a cyano group, an optionally substituted hydrocarbon group, an optionally substituted heterocyclic group or an optionally substituted hydroxy group, or (2) when A 1 is CR 4a R 4b , R 1 and R 4a and/or R 4b in combination optionally form, together with the adjacent carbon atoms, an optionally substituted 4- to 8-membered ring, or (3) when A 1 is Nr 4c , R 1 and R 4c in combination optionally form, together with the adjacent carbon atom and nitrogen atom, an optionally substituted 4- to 8-membered nitrogen-containing heterocycle; R 2 is a hydrogen atom, a cyano group or an optionally substituted hydrocarbon group; and R 3a is a group represented by the formula: —CO—SR A1 wherein R A1 is an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group, or R 3a is an optionally substituted 5- or 6-membered aromatic ring group, or a salt thereof.
