Abstract
Aim: To formulate and assess the anticancer effect of the poly(lactic-co-glycolic acid) (PLGA) copolymer with the thioether groups (diethyl sulfide [Des]) and disulfide bond (cystamine containing disulfide [Cys]), which encapsulated the anticancer drug paclitaxel (PTX) and triggered PTX release in cancer cell H2O2-rich or glutathione-rich surroundings. Methods: PLGA-b-P (Des@Cys) and PLGA-b-P nanoparticles loaded with PTX were prepared and characterized in vitro. The delivery ability of the PLGA-b-P nanoparticles and PLGA-b-P-PTX nanoparticles was assessed on a CT26 (mouse colon cancer cell line) and mouse lung cancer LLC model. Results: The nanoparticles were successfully prepared. Compared with free PTX, the formulated PLGA-b-P nanoparticles loaded with PTX exhibited greater accumulation at the tumor site in the mouse model. Conclusion: PLGA-b-P nanoparticles promote drug accumulation at tumor sites, providing an effective strategy for an intelligent, responsive drug-delivery system.

Abstract
For enhanced intracellular accumulation of 6-mercaptopurine (6-MP) in leukemia, a folate receptor-targeted and glutathione (GSH)-responsive polymeric prodrug nanoparticle was made. The nanoparticles were prepared by conjugating 6-MP to carboxymethyl chitosan via a GSH-sensitive carbonyl vinyl sulfide linkage, ultrasonic self-assembly and surface decoration with folate. The TEM graphs shows that the as-synthesized nanoparticles are spherical with a particle size of 170~220 nm. In vitro drug release of nanoparticles demonstrated acceptable stability in PBS containing 20 μM GSH at pH 7.4. However, the cumulative drug release rate of the samples containing 20 mM and 10 mM GSH medium reached 78.9% and 64.8%, respectively, in pH 5.0 at 20 h. This indicated that this nano-sized system is highly sensitive to GSH. The inhibition ratio of folate-modified nanoparticles compared to unmodified nanoparticles was higher in cancer cells (human promyelocytic leukemia cells, HL-60) while their cytotoxicity was lower in normal cells (mouse fibroblast cell lines, L929). Furthermore, in vitro cancer cell incubation studies confirmed that folate-modified nanoparticles therapeutics were significantly more effective than unmodified nanoparticles therapeutics. Our results suggest that folate receptor-targeting and GSH-stimulation can significantly elevate tumour intracellular drug release. Therefore, folate-modified nanoparticles containing chemoradiotherapy is a potential treatment for leukemia therapy.

Abstract
Tunable glutathione (GSH)-sensitive hollow mesoporous silica nanoparticles (HMSiO2 NPs) were developed using a structural difference-based selective etching strategy. These organosilica hollow nanoparticles contained disulfide linkages (S-S) in the outer shell which were degraded by GSH. The particles were compared with their nonGSH-sensitive tetraethyl orthosilicate (TEOS) HMSiO2 counterparts in terms of their synthesis method, characterization, doxorubicin (DOX) release profile, and in vitro cytotoxicity in MCF-7 breast cancer cells. Transmission electron microscopy (TEM) of the particles indicated that the fabricated HMSiO2 NPs had an average diameter of 130 ± 5 nm. Thermogravimetric analysis (TGA) revealed that GSH-sensitive particles had approximately 5.3% more weight loss than TEOS HMSiO2 NPs. Zeta potential of these redox-responsive particles was -23 ± 1 mV at pH 6 in deionized (DI) water. Nitrogen adsorption-desorption isotherm revealed that the surface area of the hollow mesoporous nanoreservoirs was roughly 446 ± 6 m2 g-1 and the average diameter of the pores was 2.3 ± 0.5 nm. TEM images suggest that the nanoparticles started to lose mass integrity from Day 1. The particles showed a high loading capacity for DOX (8.9 ± 0.5%) as a model drug, due to the large voids existing in the hollow structures. Approximately 58% of the incorporated DOX released within 14 days in phosphate buffered saline (PBS) at pH 6 and in the presence of 10 mM of GSH, mimicking intracellular tumor microenvironment while release from TEOS HMSiO2 NPs was only c.a. 18%. The uptake of these hollow nanospheres by MCF-7 cells and RAW 264.7 macrophages was evaluated using TEM and confocal microscopy. The nanospheres were shown to accumulate in the endolysosomal compartments after incubation for 24 h with the maximum uptake of c.a. 2.1 ± 0.3% and 5.2 ± 0.4%, respectively. Cytotoxicity of the nanospheres was investigated using CCK-8 assay. Results indicate that intact hollow particles (both GSH-sensitive and TEOS HMSiO2 NPs) were nontoxic to MCF-7 cells after incubation for 24 h within the concentration range of 0-1000 μg ml-1. DOX-loaded GSH-sensitive nanospheres containing 6 μg ml-1 of DOX killed c.a. 51% of MCF-7 cells after 24 h while TEOS HMSiO2 NPs killed c.a. 20% with the difference being statistically significant. Finally, cytotoxicity data in RAW 264.7 macrophages and NIH 3 T3 fibroblasts shows that intact GSH-sensitive HMSiO2 NPs did not show any toxic effects on these cells with the concentrations equal or <125 μg ml-1.

Abstract
Diblock copolymers of poly(ethylene glycol) (PEG) and biodegradable polycarbonate functionalized with GSH-sensitive disulfide bonds and pH-responsive carboxylic acid groups were synthesized via organocatalytic ring-opening polymerization of functional cyclic carbonates with PEG having different molecular weights as macroinitiators. These narrowly-dispersed polymers had predictable molecular weights, and were used to load doxorubicin (DOX) into micelles primarily through ionic interactions. The DOX-loaded micelles exhibited the requisite small particle size (<100 nm), narrow size distribution and high drug loading capacity. When exposed to endolysosomal pH of 5.0, drug release was accelerated by at least two-fold. The introduction of GSH further expedited DOX release. Effective DOX release enhanced cytotoxicity against cancer cells. More importantly, the DOX-loaded micelles with the optimized composition showed excellent antitumor efficacy in nude mice bearing BT-474 xenografts without inducing toxicity. These pH and redox dual-responsive micelles have the potential as delivery carriers to maximize the therapeutic effect of anticancer drugs.
