ReviewMolecular imaging of HPMA copolymers: visualizing drug delivery in cell, mouse and man.
N-(2-Hydroxypropyl)methacrylamide (HPMA) copolymers and their drug conjugates are some of the most intensively investigated drug delivery systems for over 30years. Some of the HPMA copolymer drug conjugates have entered clinical trials. ⋯ Magnetic resonance imaging and nuclear medicine, including gamma-scintigraphy, SPECT and PET, have been used for the non-invasive visualization of pharmacokinetics, biodistribution and drug targeting efficiency of HPMA copolymers in animal models. gamma-Scintigraphy has been used to study HPMA copolymer drug conjugates in human patients. The application of imaging technologies in the study of HPMA copolymers and properties of the copolymers demonstrated by imaging is summarized in this review.

Comparative Study Historical ArticleHPMA copolymers: origins, early developments, present, and future.
The overview covers the discovery of N-(2-hydroxypropyl)methacrylamide (HPMA) copolymers, initial studies on their synthesis, evaluation of biological properties, and explorations of their potential as carriers of biologically active compounds in general and anticancer drugs in particular. The focus is on the research in the authors' laboratory - the development of macromolecular therapeutics for the treatment of cancer and musculoskeletal diseases. In addition, the evaluation of HPMA (co)polymers as building blocks of modified and new biomaterials is presented: the utilization of semitelechelic poly(HPMA) and HPMA copolymers for the modification of biomaterial and protein surfaces and the design of hybrid block and graft HPMA copolymers that self-assemble into smart hydrogels. Finally, suggestions for the design of second-generation macromolecular therapeutics are portrayed.
