Patent ID: 7799913

Claim:
A compound having the Structure Ia or Ib: wherein: Q and Q′ are independently hydrogen, —CH 2 —, —O—, —S—or alkyl, or, when Y or R 3 serve to link the aromatic ring to A, hydroxyalkyl or alkoxyalkyl, R 1 is hydrogen, alkyl or together with Q may be a cycloalkyl ring, R 2 is absent when Q and Q′ are independently hydrogen, alkyl, hydroxyalkyl or alkoxyalkyl, or if present, is —CH 2 —, —CO—, —CH 2 CH 2 —, —CH 2 CO—, —CH 2 O—, —CRR′—, or —CONR—, Y is hydrogen or —OR 3 , or serves to link the aromatic ring to A or A′ as a single bond, ═N—or —NR—, R 3 is hydrogen, alkyl, substituted alkyl, or serves to link the attached oxygen to A or A′ by being a lower alkylene or substituted lower alkylene linking the aromatic ring to A or A′ to form a substituted or unsubstituted 6, 7 or 8—membered ring, or a bond linking the oxygen to A or A′ in order to form a 5—or 6—membered ring, A is —NRR′, —OR, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, cycloalkylalkyl, aryl, substituted aryl, a heterocycle or a substituted heterocycle containing one or two heteroatoms selected from the group consisting of oxygen, nitrogen, sulfur and mixtures thereof, A′ is —NRR′, R is hydrogen, aryl, arylalkyl, substituted aryl, substituted arylalkyl, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, or heterocycloalkyl, R′ is absent or is hydrogen, aryl, arylalkyl, substituted aryl, substituted arylalkyl, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl or may join together with R to form a 4- to 8- membered ring, which may be substituted by X and may be linked to Y to form a 6- membered ring and which may optionally contain one or two heteroatoms selected from the group consisting of oxygen, nitrogen, sulfur and mixtures thereof, X and X′ are independently R, halo, —CO 2 R, —CN, —NRR′, —NRCOR′, —NO 2 , —N 3 or —OR.
