Patent ID: 7629383

Claim:
A compound of formula I where n is an integer having a value of 5 to 12; R 1 is an optionally unsaturated C 1-15 alkyl group optionally substituted with one or more of hydroxyl groups, oxo groups, halogenyl groups, alkoxy groups, acyloxy groups, thiol groups, amino groups, alkylthio groups, and alkylamino groups, or is a group —CHR 3 —O—CO—R 2 ; each R 2 independently is an optionally unsaturated C 1-15 alkyl or alkoxy group, an aryl, alkaryl, aralkyl, aryloxy, alkaryloxy or aralkoxy group having up to 16 carbons, wherein any alkyl group is optionally substituted with one or more of hydroxyl groups, oxo groups, halogenyl groups, alkoxy groups, acyloxy groups, thiol groups, amino groups, aromatic groups, alkylthio groups, and alkylamino groups, or together with the R 3 gamma to it is a 2 to 5 backbone atom bridging group; and each R 3 independently is hydrogen, an optionally unsaturated C 1-15 alkyl group optionally substituted with one or more of hydroxyl groups, oxo groups, halogenyl groups, alkoxy groups, acyloxy groups, thiol groups, amino groups, aromatic groups, alkylthio groups, and alkylamino groups, or is a group R 2 —CO—O— or together with R 2 forms a 2 to 5 backbone atom bridging group, or a physiologically tolerable salt thereof, provided that the compound of formula I is not bis(1-(acetyloxy)ethyl) nonanedioate.
