The biological activities of sequential combinations of anticancer drugs, SOS thiophene (SOS) and mesochlorin e 6 monoethylenediamine (Mce 6), in the form of free drugs, nontargeted N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer-drug conjugates, P-GFLG-Mce 6 and P-GFLG-SOS (P is the HPMA copolymer backbone and GFLG is the glycylphenylalanylleucylglycine(More)
BACKGROUND There is an immense clinical need for novel therapeutics for the treatment of angiogenesis-dependent calcified neoplasms such as osteosarcomas and bone metastases. We developed a new therapeutic strategy to target bone metastases and calcified neoplasms using combined polymer-bound angiogenesis inhibitors. Using an advanced "living(More)
N-(2-Hydroxypropyl)methacrylamide (HPMA) copolymer-bound doxorubicin has showed greater potency than free doxorubicin in the treatment of ovarian cancer in vivo and in vitro. The promising activity of the conjugate demonstrated in clinical trials has generated considerable interest in understanding the mechanism of action of this macromolecular therapeutic.(More)
Many studies have described macromolecular conjugates designed to deliver antitumour agents lysosomotropically Monsigny et al., 1980). Such conjugates should be stable in the extracellular environment, but degrade intralysosomally via pH mediated hydrolysis or enzymatic cleavage to liberate the cytotoxic drug. Recently, it has been demonstrated that the(More)
