The invention provides new lipopolyamines of spermine type of the general formula I, wherein X is C-N bond or aminopolyethyleneglycolcarboxamide linker or o-hydroxy- alkylcarboxamide linker or ω-hydroxyalkylcarboxamidopolyethyleneglycol- carboxamide linker, and wherein a hydrophobic domain Y is an acyl symmetrically branched in the position C(2) or cholesteryl. The invention further provides a method of preparation of said lipopolyamines and their use for construction of polycationic liposomal drug carriers.

Supramolecular assemblies for delivering active agents to cancerous or precancerous tissues in a subject are provided. These supramolecular assemblies are also useful in assays for detecting and imaging of cancerous and precancerous cells. The assemblies are protease-sensitive and comprise a peptide linkage containing a protease consensus sequence. The assemblies can be selectively targeted to cancerous tissue where the protease enzymes degrade the peptide linkage thereby releasing the active agents which were physically or mechanically contained in or retained by the supramolecular assembly.
