| abstract |
The present invention provides a composition comprising (i) a lipid compound comprising at least one non-polar moiety and a polar moiety, wherein the non-polar moiety is of the formula X-Y-Z- wherein X is an acetylenic hydrocarbyl group containing a single C≡C bond, Y is O or CH 2 , and Z is an optional hydrocarbyl group, wherein the polar moiety is of the formula -[T] m PHG, wherein [T] m is an optional group selected from C(O), NH, NR 1 , NHC(O), C(O)NH, NRIC(O) and C(O)NR 1 and CH 2 , where R 1 is a hydrocarbyl group, wherein PHG is a polar head group, and wherein m is the number of non-polar moieties (ii) a therapeutic agent. |
