  Enhanced cytotoxicity of a polymer–drug conjugate with triple payload of paclitaxel

  摘要：

  The development of targeting approaches to selectively release chemotherapeutic drugs into malignant tissue is a major challenge in anticancer therapy. We have synthesized an N-(2-hydroxypropyl)-methacrylamide (HPMA) copolymer-drug conjugate with an AB(3) self-immolative dendritic linker. HPMA copolymers are known to accumulate selectively in tumors. The water-soluble polymer-drug conjugate was designed to release a triple payload of the hydrophobic drug paclitaxel as a result of cleavage by the endogenous enzyme cathepsin B. The polymer-drug conjugate exhibited enhanced cytotoxicity on murine prostate adenocarcinoma (TRAMP C2) cells in comparison to a classic monomeric drug-polymer conjugate. (C) 2009 Elsevier Ltd.

  Polymeric systems useful for theranostic applications are disclosed. The polymeric systems comprise a fluorescent or fluorogenic moiety and a therapeutically active agent, each attached to the same or different polymeric moiety. The polymeric systems are designed such that a fluorescent signal is generated in response to a chemical event, preferably upon contacting an analyte (e.g., an enzyme) that is over- expressed in a diseased tissue or organ. Probes useful for inclusion in such polymeric systems, processes of preparing such probes and the polymeric systems, and uses thereof in diagnostic and/or theranostic applications are also disclosed.

  The generation of rationally designed polymer therapeutics via the conjugation of low molecular weight anti-cancer drugs to water-soluble polymeric nanocarriers aims to improve the therapeutic index. Here, we focus on applying polymer therapeutics to target two cell compartments simultaneously - tumour cells and angiogenic endothelial cells. Comparing different polymeric backbones carrying the same therapeutic agent and targeting moiety may shed light on any correlation between the choice of polymer and the anti-cancer activity of the conjugate. Here, we compared three paclitaxel (PTX)-bound conjugates with poly-l-glutamic acid (PGA, 4.9mol%), 2-hydroxypropylmethacrylamide (HPMA, 1.2mol%) copolymer, or polyethyleneglycol (PEG, 1:1 conjugate). PGA and HPMA copolymers are multivalent polymers that allow the conjugation of multiple compounds within the same polymer backbone, while PEG is a bivalent commercially available Food and Drug Administration (FDA)-approved polymer. We further conjugated PGA-PTX and PEG-PTX with the integrin alpha(v)beta(3)-targeting moiety RGD (5.5mol% and 1:1 conjugate, respectively). We based our selection on the overexpression of integrin alpha(v)beta(3) on angiogenic endothelial cells and several types of cancer cells. Our findings suggest that the polymer structure has major effect on the conjugate's activity on different tumour compartments. A multivalent PGA-PTX-E-[c(RGDfK)(2)] conjugate displayed a stronger inhibitory effect on the endothelial compartment, showing a 50% inhibition of the migration of human umbilical vein endothelial cell cells, while a PTX-PEG-E-[c(RGDfK)(2)] conjugate possessed enhanced anti-cancer activity on MDA-MB-231 tumour cells (IC50 = 20 nM versus IC50 300 nM for the PGA conjugate).
