The present invention relates to water-soluble high-molecular polymeric carriers of medicaments and their conjugates with medicaments, derived from dendrimers based on poly (amidoamine) and 2,2-bis(hydroxymethyl)propionic dendrimer, the amino and hydroxy end groups of which are attached to semitelechelic copolymers of N-(2 hydroxypropyl)methacrylamide (HPMA) through the mediation of biodegradable spacers. The polymer carriers and conjugates of the present invention enable targeted transport notably of anticancer medicaments into solid tumors in which biodegradation, the associated controlled drug release and subsequent elimination of polymer carrier from the organism are provided. The efficiency of the polymer carrier conjugated with a cancerostatic is directed to targeted therapy of human tumors.
