Patents Assigned to USTAV MAKROMOLEKULARNI CHEMIE AV CR, V.V.I.
  • Publication number: 20210283568
    Abstract: The present invention relates to a process for ion irradiation of a particulate substrate containing the steps of embedding particulate substrate in a solid matrix having 10B atoms, and exposing the matrix obtained in the previous step to a neutron flux to give irradiated particulate substrate. The process is extremely effective and amenable to large scale and is particularly suitable for producing irradiated nanodiamonds and irradiated SiC particles.

  • Patent number: 10626209
    Abstract: The present invention relates to the preparation and use of copolymers composed of N-(2-hydroxypropyl) methacrylamide (HPMAA) and carboxybetaine methacrylamide (CBMAA). The invention further describes polymer brushes having structure I S—R-polymer??(I) wherein S is a substrate; R is a residue of a polymerization initiator or a RAFT agent bound to the substrate; and “polymer” is the copolymer of N-(2-hydroxypropyl) methacrylamide and carboxybetaine methacrylamide Furthermore, production of these polymer brushes, containing random or block copolymers grafted to or from a substrate is described. The copolymer brushes are suitable for protecting substrates from deposition and/or adhesion of biological substances, and/or against thrombus formation. The brushes functionalized by covalent attachment of bioactive substances to CBMAA monomer units are particularly suitable for specific interaction with target biological substances which is not affected by nonspecific deposition of non-target compounds.

  • Patent number: 9173949
    Abstract: The present invention relates to water-soluble high-molecular-weight polymer drug carriers and their conjugates with drugs, derived from dendrimers of the amidoamine and 2,2-bis(hydroxymethyl)propanoic types, the amino and hydroxy end groups of which are attached to semitelechelic copolymers of N-(2 hydroxypropyl)methacrylamide (HPMA) through biodegradable spacers. The polymer carriers and conjugates enable targeted transport notably of anticancer drugs into solid tumors in which biodegradation, the associated controlled drug release and subsequent elimination of polymer carrier from the organism are provided. The polymer carrier conjugated with a cancerostatic for use in targeted therapy of human tumors.
