    Liposomal formulations prepared by extrusion from natural phospholipids and 1,2-dioleoylglycerol conjugates of methotrexate and melphalan (egg phosphatidylcholine–phosphatidylinositol–prodrug, 8:1:1, by mol.) were characterized by size, composition and stability. Both prodrugs were shown to incorporate completely into unilamellar liposomes with the mean size below 100 nm and form stable dispersions containing the drug concentrations relevant for systemic injections in animals. For long-term storage, the dispersions can be  subjected to deep freezing (- 196°C) and stored at - 70°C; before usage, they should be defrosted and treated shortly in an ultrasonic bath. According to the example of methotrexate conjugate, stability of prodrug ester bond in liposomal formulation towards hydrolysis by human plasma esterases during 24-h incubation were established. Also, liposomes bearing methotrexate conjugate were shown to overcome resistance of human leukemia cells related to impaired transport of initial drug across the membrane.

    Tetraantennary peptides [glycine(n)-NHCH(2)](4)C can form stable noncovalent structures by self-assembly through intermolecular hydrogen bonding. The oligopeptide chains assemble as polyglycine II to yield submicron-sized, flat, one-molecule-thick sheets. Attachment of alpha-N-acetylneuraminic acid (Neu5Acalpha) to the terminal glycine residues gives rise to water-soluble assembled glycopeptides that are able to bind influenza virus multivalently and inhibit adhesion of the virus to cells 10(3)-fold more effectively than a monomeric glycoside of Neu5Acalpha. Another antiviral strategy based on virus-promoted assembly of the glycopeptides was also demonstrated. Consequently, the self-assembly principle offers new perspectives on the design of multivalent antivirals.
