Patent ID: 8110555

Claim:
A method for treating ROS mediated diseases and conditions comprising administering to a host in need thereof an effective amount of a composition comprising a 7-hydroxychromone or a mixture of 7-hydroxychromones wherein said 7-hydroxychromone or a mixture thereof is selected from the group of compounds having the following structure: wherein R l is an oxoalkyl or oxoalkenyl group; R 2 and R 3 are independently selected from the group consisting of —H, —OH, alkyl, alkenyl, oxoalkyl, oxoalkenyl, hydroxylalkyl, hydroxylalkenyl, —OR, —SR, —NH 2 , —NRH, —NR 2 , —NR 3 + X − , an ester selected from the group consisting of gallate, acetate, cinnamoyl and hydroxyl-cinnamoyl esters, trihydroxybenzoyl esters and caffeoyl esters; and a carbon, oxygen, nitrogen or sulfur glycoside of a single or a combination of multiple sugars selected from the group consisting of aldopentoses, methyl aldopentose, aldohexoses, ketohexoses; wherein said alkyl and/or alkenyl group is a straight and/or branched chain having between 1-20 carbon atoms with and/or without double bonds in different positions; X is selected from the group of pharmaceutically acceptable counter anions consisting of hydroxyl, chloride, iodide, sulfate, phosphate, acetate, fluorideand carbonate; R is an alkyl group having between 1-20 carbon atoms and wherein the composition is comprised of 1% to 100% of said 7-hydroxychromones.
