The synthesis, characterization, and results of evaluation of the biological behavior of N-(2-hydroxy-propyl)methacrylamide (HPMA) copolymer conjugates bearing anti-cancer drugs doxorubicin and mitomycin C are described. Two HPMA copolymer carrier types were synthesized: the linear copolymer and the biodegradable high-molecular-weight diblock copolymer containing a degradable disulfide bond. The polymer-drug conjugates incubated in buffers modeling the intracellular environment released the drugs more rapidly than those incubated in bloodstream conditions. Significant in vitro and in vivo antitumor synergistic activity of the conjugates in the treatment of EL-4 T-cell demonstrates their high potential for solid tumor treatment.
