Abstract:
The present invention relates to compounds and their uses, in particular, compounds in the form of prodrugs that promote transport of a pharmaceutical agent to the lymphatic system and subsequently enhance release of the parent drug.

Claim (Index 24):
A compound of formula (I): wherein R 1  and R 2  independently represent H or a residue of a C 2 -C 28  fatty acid; \u2014X\u2014 is \u2014O\u2014; \u2014Y\u2014 represents an optionally substituted \u2014C 3 -C 20 alkyl-, \u2014C 3 -C 20 alkenyl-, or \u2014C 3 -C 20 alkynyl-group, wherein one or more of the carbon atoms in the alkyl, alkenyl, or alkynyl group may be replaced with NH, S, or O, provided that the alkyl, alkenyl, or alkynyl group does not exceed a length equivalent to a linear C 20 alkyl group; represents a residue of a pharmaceutical agent;\n -L- is \u2014X\u2032\u2014 or \u2014X\u2032C(O)\u2014; \n X\u2032 is O, S, N, N(R 4 ), or S(O) 2 NH; \n  represents a single bond when X\u2032 is O, S, N(R 4 ), or S(O) 2 NH; or \n  represents two separate bonds when X\u2032 is N; \n \u2014Z\u2014 is \u2014C(O)\u2014 or \u2014C(O)R 3 \u2014 when -L- is \u2014X\u2032\u2014; or \n \u2014Z\u2014 is absent when -L- is \u2014X\u2032C(O)\u2014; \n R 3  is a self-immolative group; and \n R 4  is H or C 1 -C 4 alkyl; \n provided that \u2014Y\u2014 is substituted or \u2014Z\u2014 is \u2014C(O)R 3 \u2014; \n or \u2014Y\u2014 is substituted and \u2014Z\u2014 is \u2014C(O)R 3 \u2014; \n or a pharmaceutically acceptable salt thereof.
