Doxorubicin (DOX) resistance, which results in a reduced accumulation of DOX in the nucleus and hence decreased DNA damage, is a major challenge for chemotherapy against hepatocellular carcinoma. In this paper, we combined chemotherapy with photodynamic therapy (PDT) to combat DOX-resistant human hepatocellular carcinoma cells. We have prepared the polymeric micelles conjugating with DOX and zinc(II) phthalocyanine (ZnPc) through a pH-responsive hydrazone linker and a glutathione (GSH)-responsive disulfide linker, respectively. The polymeric micelles (DOX-ZnPc-micelles) exhibited a spherical shape with a size of about 98 mn diameter and showed excellent stability in aqueous solution. Due to the self-quenching of the ZnPc inside the micelles, DOX-ZnPc-micelles did not emit fluorescence upon red light irradiation. Drug release experiments verified that DOX and ZnPc could be released under acidic conditions and reducing environments, respectively. A higher concentration of DOX was internalized into DOX-resistant R-HepG2 cells through the delivery of polymeric micelles when compared with the free DOX, hence DOX-ZnPc-micelles exhibited a significant enhancement in anticancer activity. The IC50 value of DOX against R-HepG2 cells was found to be 21 mu M when combined with PDT and it was 5-fold less than that of a single treatment of DOX (102 mu M). The DOX-ZnPc-micelles could induce cell apoptosis and necrosis on R-HepG2 cells by combined therapeutic modalities, while these micelles induced only apoptosis on IiepG2 cells. We have demonstrated that utilization of polymeric micelles can significantly enhance the cellular uptake and cytotoxicity of DOX against R-HepG2 cells when compared with free DOX. Moreover, PDT can act as an adjuvant therapeutic modality and combine with chemotherapy to further improve therapeutic efficacy. Overall speaking, DOX-ZnPc-micelles can overcome DOX resistance and induce a synergistic therapeutic effect against DOX-resistant R-HepG2 cells, hence improving the therapeutic efficacy when compared with monotherapy.

A triply responsive amphiphilic polymer containing poly (ethylene glycol) (PEG) and pyrene linked by a disulfide bond (PEO-SS-PY) was synthesized. Benefiting from its amphiphilicity, PEO-SS-PY could self-assemble into 126 nm micelles in water. PEO-SS-PY with CB[7] forms a 1:1 pseudorotaxane polymer (PEO-SS-Py@CB[7]) in aqueous solution. After the formation of host-guest complex, the micelles size increased to 136 nm and the fluorescence emission intensity increased. Glutathione would break the disulfide bond, leading to the dissociation of the micelles. Spermine and adamantanamine hydrochloride would dissociate the host-guest complex, leading to change of micelle size and decrease of fluorescence intensity. More interestingly, this self-assembly micelle displayed highly sensitive response to Fe3+. Because the effective absorption of Fe3+ hindered the absorption of PEO-SS-Py@CB[7] at the excitation wavelength of 405 nm, Fe3+ distinctly quenched the fluorescence emission of PEO-SS-Py@CB[7], whereas, a very low changes of intensity was observed for other metal ions. Results of this paper provide a new idea for the combination of metal ion detection and controlled release.

Chemo-photodynamic combined therapy is promising in cancer treatment, although low tissue penetration of visible light for activating photosensitizers (e.g., chlorin e6, Ce6) limited its broad applications. Combination of upcoverting nanoparticles (UCNPs) with the photosensitizers endows us with the possibility to utilize highly tissue penetrable near-infrared light; nevertheless, the mismatch between absorption of common photosensitizers (lambda(abs), mainly red) and emission of UCNPs (lambda(em), mainly green) resulted in low energy utilization and unsatisfied therapeutic efficacy in the current UCNP-PDT (photodymanic therapy) platforms. To resolve this problem, herein, we construct polymer-UCNP hybrid micelles (PUHMs) for codelivery of doxorubicin (DOX) and Ce6, and systemically studied the effects of spectral match between lambda(em) of UCNPs and lambda(abs) of Ce6 on efficiency of synergistic chemo-photodynamic therapy. Compared with spectrally mismatched PUHMs, the spectrally matched PUHMs can significantly enhance the utilization efficiency of upconverted emission energy to activate the photosensitizers and generate more reactive oxygen species (ROS) for enhanced photodynamic therapy. Meanwhile, as the assembled structure of PUHMs can be destroyed by the oxidation of ROS upon 980 nm laser irradiation because of the hydrophobic-hydrophilic transformation of poly(propylene sulfide) (PPS) segment, the spectrally matched PUHMs triggered faster release of DOX, thus resulting in more effective chemotherapy. As a result, the spectrally matched PUHMs induced more prominent cytotoxicity and superior synergistic therapeutic effect for cancer cells in vitro. Our results demonstrated that such spectrally matched PUHMs provide us with an effective strategy for photodynamic-chemo synergistic therapy.

Clinical application of drug cocktails for cancer therapy is limited by their severe systemic toxicity. To solve a catch-22 dilemma between safety and efficacy for drug cocktails, a heterotargeted nanococktail (PPPDMA) with traceless linkers is developed. In the PPPDMA nanogel, a heterotargeting strategy is employed to improve its tumor selective targeting efficacy by overcoming the cancer cell monoligand density limitation. Benefitting from its glutathione and reactive oxygen species responsiveness, the loaded paclitaxel and doxorubicin can be quickly and tracelessly released into the cytoplasm in their original form, which bestows upon PPPDMA nanogels the capability to overwhelm the processing capacity of the cancer cell’s P-glycoprotein efflux pump, and ultimately kill them without inducing side effects. The PPPDMA treatment reduced its tumor burden over 99% (in tumor weight) and 96% (in tumor number). Most importantly, no detectable tumor in more than half of the PPPDMA treated mice was observed. It is concluded that traceless linker and heterotargeted nanococktail strategy can be a safe and effective approach for cancer treatment.

Novel chitosan-cystamine-retinoic acid conjugate (CS-SS-RA) was synthesized and could self-assemble into redox-sensitive micelles in aqueous environment with low critical micelle concentration value. CS-SS-RA micelles were characterized with spherical shape, desirable particle size, negative zeta potential, high paclitaxel (PTX) loading and encapsulation efficiency and redox-sensitivity. Hemolysis and cytotoxicity studies proved the safety of CS-SS-RA micelles for intravenous administration. Cytotoxicity study against HepG2 cells and the growth inhibition study on three-dimensional multicellular tumor spheroids (MCTSs) revealed that PTX-loaded CS-SS-RA micelles exhibited higher antitumor activity than free PTX. The in vitro cellular uptake profiles of FITC-labeled CS-SS-RA micelles evaluated via confocal laser scanning microscopy and flow cytometry indicated that CS-SS-RA micelles could enhance cellular uptake efficiency of PTX, and their internalization by HepG2 cells were mediated by clathrin-mediated endocytosis and macropinocytosis. These results demonstrated that CS-SS-RA micelles could be developed as a promising platform for intracellular delivery of hydrophobic antitumor agents.

The surface chemistry of colloidal silica has tremendous effects on its properties and applications. Commonly the design of silica particles is based on their de novo synthesis followed by surface functionalization leading to tailormade properties for a specific purpose. Here, the design of robust precursor polymer-decorated silica nano- and microparticles is demonstrated, which allows for easy post-modification by polymer embedded thiolactone chemistry. To obtain this organic-inorganic hybrid material, silica particles (SiO2P) were functionalized via surface-initiated atom transfer radical polymerization (SI-ATRP) with poly(2-hydroxyethyl acrylate) (PHEA)-poly(thiolactone acrylamide (PThlAm) co-polymer brushes. Exploiting the versatility of thiolactone post-modification, a system was developed that could be used in three exemplary applications: 1) the straightforward molecular post-functionalization to tune the surface polarity, and therefore the dispersibility in various solvents; 2) the immobilization of metal nanoparticles into the polymer brushes via the in situ formation of free thiols that preserved catalytic activity in a model reaction; 3) the formation of redox-responsive, permeable polymer capsules by crosslinking the thiolactone moieties with cystamine dihydrochloride (CDH) followed by dissolution of the silica core.

Amphiphilic derivatives of (+/-)-trans-1,2-diselenane-4,5-diol (DSTox) decorated with long alkyl chains or aromatic substituents via ester linkages were applied as glutathione peroxidase (GPx)-like catalysts. The reduction of H2O2 with the diselenide catalysts was accelerated through a GPx-like catalytic cycle, in which the diselenide (Se-Se) bond was reduced to the diselenolate form ([Se-,Se-]) by coexisting dithiothreitol, and the generated highly active [Se-,Se-] subsequently reduced H2O2 to H2O retrieving the original Se-Se form. In the lipid peroxidation of lecithin/cholesterol liposomes induced by 2,2′-azobis(2-amidinopmpane) dihydrochloride (AAPH), on the other hand, the Se-Se form directly reduced lipid peroxide (LOOH) to the corresponding alcohol (LOH), inhibiting the radical chain reaction, to exert the antioxidative effect. Thus, the two GPx-like catalytic cycles can be switched depending on the peroxide substrates. Furthermore, hydrophilic compounds with no or short alkyl groups (C3) showed high antioxidative activities for the catalytic reduction of H2O2, while lipophilic compounds with long alkyl chains (C6-C14) or aromatic substituents were more effective antioxidants against lipid peroxidation. In addition, these compounds showed low cytotoxicity in cultured HeLa cells and exhibited sufficient anti-lipid peroxidative activities, suggesting their potentials as selenium-based antioxidative drugs.
