  • 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.

  • Patent number: 4062831
    Abstract: The invention relates to copolymers based on N-substituted acrylamides, N-substituted methacrylamides and N,N-disubstituted acrylamides and to a method for their manufacturing, which copolymers are prepared under conditions when the phase separation takes place. The resulting copolymer contains reactive groups and serves as the intermediate for preparation of biologically active compounds (enzymes, hormones, drugs, etc.) bonded to the polymer. The procedure according to the invention enables to prepare porous polymers suitable as separation barriers (membranes) or column packings for gel or affinity chromatography, if the polymerization is carried out in the presence of a divinyl component.
