摘要

The present invention relates to a compound having the formula XXX
or
wherein R 1 is a C 5 or greater branched or straight chain alkyl group;
R 2 is hydrogen, a C 1 -C 15 branched or straight chain alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted cycloalkyl group, or R 1 and R 2 collectively form a substituted or unsubstituted fused aryl group; and
R 3 is one or more groups comprising, independently, hydrogen, a C 1 -C 15 branched or straight chain alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted cycloalkyl group;
R 6 and R 7 are, independently, hydrogen, a C 1 -C 15 branched or straight chain alkyl group, or a substituted or unsubstituted cycloalkyl group;
R 11 is hydrogen or a C 1 -C 15 branched or straight chain alkyl group; and n is from 0 to 3,
wherein one or more carbon atoms in the ring in formula XXX can optionally be replaced with a heteroatom, or the pharmaceutically-acceptable salt or ester thereof,
wherein the compound is not (2E,4E,6Z,8E)-8-(3',4'-dihydro-1'(2'H-naphthalen-1'-ylidene))-3,7-dimethyl-2,4,6-octatrienoic acid or an ester thereof; (2E,4E,6E,8E)-8-(3',4'-dihydro-1'(2'H-naphthalen-1'-ylidene))-3,7-dimethyl-2,4,6-octatrienoic acid or an ester thereof; (2E,4E,6Z,8E)-8-(3',4'-dihydro-4'methyl-1'(2'H-naphthalen-1'-ylidene))-3,7-dimethyl-2,4,6-octatrienoic acid or an ester thereof; and (2E,4E,6Z,8E)-8-(3',4'-dihydro-5',7'-dimethyl-1'(2'H-naphthalen-1'-ylidene))-3,7-dimethyl-2,4,6-octatrienoic acid or an ester thereof.
