Abstract: The present invention relates to platinum (IV) prodrug lipid-based amphiphiles and compositions thereof. In particular, it relates to cisplatin, oxaliplatin and carboplatin prodrugs with the capacity to make stable liquid crystalline nanoparticles and crystalline nanoparticles, and uses thereof to treat cancer in animals, including humans.

Abstract: The present invention relates to improved prodrugs, and compositions thereof. In particular, it relates to amphiphilic gemcitabine prodrugs or amphiphilic prodrugs of other biologically active molecules with the capacity to make liquid crystalline nanostructured nanoparticles, and uses thereof to treat animals, including humans.

Abstract: Amphiphilic prodrugs of general formula A-X are disclosed, wherein A is a biologically active agent or may be metabolized to a biologically active agent; and X is R, or up to three R moieties attached to a linker, Y1, Y2 or Y3. Self-assembly of the amphiphilic prodrugs into reverse lyotropic phases, particularly hexagonal, cubic and sponge, is disclosed.

Abstract: Amphiphilic prodrugs of general formula A-X are disclosed, wherein A is a biologically active agent or may be metabolised to a biologically active agent; and X is selected from the group consisting of R, or up to three R moieties attached to a linker, Y1, Y2 or Y3, wherein R is selected from a group consisting of alkyl, alkenyl, alkynyl, branched alkyl, branched alkenyl, branched alkynyl, substituted alkyl, substituted alkenyl and substituted alkynyl groups and their analogues; Y1 is a linker group which covalently attached to an R group at one site and is attached to A at a further independent site; Y2 is a linker group which is covalently attached to two R groups at two independent sites and is attached to A at a further independent site; and Y3 is a linker group which is covalently attached to three R groups at three independent sites and is attached to A at a further independent site.
