Patent ID: 8299092

Claim:
Derivatives of 2-phenyl-3-hydroxyquinoline-4(1H)-one of the general formula (II), where X represents a nitro group and Y represents an oxygen atom substituted by a C 1 to C 6 carbon chain where the alkyl may be substituted with a halogen, hydroxy, or an alkoxy group with from 1-4 carbon atoms; an oxygen atom substituted with a phenyl group, where the phenyl may be substituted with a halogen, hydrogen or alkoxy group with from 1-4 carbon atoms; a sulfur atom substituted with a C 1 to C 6 carbon chain where the alkyl may be substituted with a halogen, hydroxy, or an alkoxy group with from 1-4 carbon atoms; a sulfur atom substituted with a phenyl group where the phenyl may be substituted with a halogen, a hydroxy or an alkoxy group with from 1-4 carbon atoms; a nitrogen atom substituted with hydrogen; a nitrogen atom substituted with a hydrogen and a C 1 to C 6 carbon chain where the alkyl may be substituted with a halogen, hydroxy, or an alkoxy group with from 1-4 carbon atoms; a nitrogen atom substituted independently with a C 1 to C 6 carbon chain where the alkyl may be substituted with a halogen, hydroxy, or an alkoxy group with from 1-4 carbon atoms and a C 1 to C 6 carbon chain where the alkyl may be substituted with a halogen, hydroxy, or an alkoxy group with from 1-4 carbon atoms; and a saturated or unsaturated 5 to 7 membered ring where 1 or 2 atoms are independently a nitrogen or oxygen atom.
