Patent ID: 7820631

Claim:
A compound having the formula: wherein Ar is a substituted aromatic ring system, the aromatic ring system comprising one six-membered aromatic ring, the aromatic ring system being substituted in the para position with an unbranched unsubstituted alkyl or alkoxy moiety, wherein the alkyl or alkoxy moiety, in total, comprises from 3 to 8 carbon atoms; R 8 and R 9 are each independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, halogens, amino, alkylamino, dialkylamino, nitro, cyano, alkoxy, aryloxy, thiol, alkylthiol, arylthiol, and aryl; Q is selected from the group consisting of O, S and CY 2 , where Y may be the same or different and is selected from H, alkyl and halogens; X is selected from the group consisting of O, NH, S, N-alkyl, (CH 2 ) m where m is 1 to 10, and CY 2 where Y may be the same or different and is selected from hydrogen, alkyl and halogens; Z is selected from the group consisting of O, S, NH, and N-alkyl; U″ is H and U′ is selected from H and CH 2 T, or U′ and U″ are joined so as to form a ring moiety including Q wherein U′—U″ together is respectively selected from the group consisting of —CTH—CT′T″ and —CT′—CT′-, so as to provide ring moieties selected from the group consisting of: wherein: T is selected from the group consisting of OH, H, halogens, O-alkyl, O-acyl, O-aryl, CN, NH 2 and N 3 ; T′ is selected from the group consisting of H and halogens and, where more than one T′ is present, they may be the same or different; T″ is selected from the group consisting of H and halogens; and W is selected from the group consisting of H, a phosphate group and a pharmacologically acceptable salt thereof.
