This paper describes the synthesis and biological evaluation of a conjugate of the highly cytotoxic drug 2-pyrrolinodoxorubicin (p-DOX) with an N-(2-hydroxypropyl) methacrylamide copolymer (PHPMA) as a water-soluble biocompatible polymer carrier, utilizing the advantageous concept of polymer–drug conjugates. The conjugate of p-DOX with HPMA copolymer (PHPMA/p-DOX) was prepared by reacting the PHPMA/DOX conjugate, where ...
