Abstract
α-Mangostin-rich extract (AME) shows promise as a functional ingredient for cancer chemotherapy. Here, we encapsulated AME in our originally designed antioxidant nanoparticles (NanoAOX) to increase its solubility and prevent oxidative degradation (AME@NanoAOX). In this study, two types of self-assembled polymers containing nitroxide radicals were engineered. These polymers were self-assembled into nanoscale particles in aqueous media, entrapping AME (abbreviated as AME@NanoAOX(B) and AME@NanoAOX(G)). These formulations considerably improved the stability of AME against oxidative degradation and exhibited different release profiles of α-mangostin under different pH conditions. Furthermore, AME-encapsulated nanoparticles exhibited potent cytotoxicity against various cancer cell lines, including human breast cancer (MCF-7), human lung cancer (A549), human colon cancer (Caco-2), human cervical cancer (HeLa), and human liver cancer (HepG2) cell lines, with minimal cytotoxicity in normal human mammary epithelial cells (hTERT-HME1), thus providing a high selectivity index (SI). These results indicated the promising feature of AME-encapsulated antioxidant nanoparticles (AME@NanoAOX) for cancer chemotherapy.

Abstract
Doxorubicin (DOX) is a natural antibiotic with antineoplastic activity. It has been used for over 40 years and remains one of the most used drugs in chemotherapy for a variety of cancers. However, cardiotoxicity limits its use for long periods. To overcome this limitation, encapsulation in smart drug delivery systems (DDS) brings advantages in comparison with free drug administration (i.e., conventional anticancer drug therapy). In this review, we present the most relevant nanostructures used for DOX encapsulation over the last 10 years, such as liposomes, micelles and polymeric vesicles (i.e., polymersomes), micro/nanoemulsions, different types of polymeric nanoparticles and hydrogel nanoparticles, as well as novel approaches for DOX encapsulation. The studies highlighted here show these nanoformulations achieved higher solubility, improved tumor cytotoxicity, prolonged DOX release, as well as reduced side effects, among other interesting advantages.

Abstract
In this study, to enhance the therapeutic function and reduce the side-effects of doxorubicin (DOX), a biodegradable N-(2-hydroxypropyl) methacrylamide (HPMA) polymer-DOX conjugate has been prepared through reversible addition fragmentation chain transfer (RAFT) polymerization and conjugation chemistry, and the anticancer agent DOX was covalently linked to the polymeric vehicle through a pH-responsive hydrazone bond. The cellular mechanisms of the conjugate were explored, and the therapeutic indexes were studied as well. The high molecular weight (MW) polymeric conjugate (94 kDa) was degraded into products with low MW (45 kDa) in the presence of lysosomal cathepsin B and also showed pH-responsive drug release behavior. In vitro cellular mechanism studies revealed that the polymeric conjugate was uptaken by the 4T1 cells, leading to cell apoptosis and cytotoxicity to cancer cells, while the polymeric conjugate demonstrated excellent in vivo biosafety even at a high dose. Compared to free DOX, the conjugate has a much longer half-life in pharmacokinetics and accumulates in tumors with a much higher amount. The conjugate therefore has a much greater in vivo anticancer efficacy against 4T1 xenograft tumors and shows subtle side-effects, which were confirmed via tumor size and weight, immunohistochemistry and histological studies. Overall, this polymeric conjugate may be used as an enzyme/pH-sensitive anticancer agent.

Abstract
Transferrin (Tf)-templated luminescent blue copper nanoclusters (Tf-Cu NCs) are synthesized. They are further formulated into spherical Tf-Cu NC-doxorubicin nanoparticles (Tf-Cu NC-Dox NPs) based on electrostatic interaction with doxorubicin (Dox). The as-synthesized Tf-Cu NC-Dox NPs are explored for bioimaging and targeted drug delivery to delineate high therapeutic efficacy. Förster resonance energy transfer (FRET) within the Tf-Cu NC-Dox NPs exhibited striking red luminescence, wherein the blue luminescence of Tf-Cu NCs (donor) is quenched due to absorption by Dox (acceptor). Interestingly, blue luminescence of Tf-Cu NCs is restored in the cytoplasm of cancer cells upon internalization of the NPs through overexpressed transferrin receptor (TfR) present on the cell surface. Finally, gradual release of Dox from the NPs leads to the generation of its red luminescence inside the nucleus. The biocompatible Tf-Cu NC-Dox NPs displayed superior targeting efficiency on TfR overexpressed cells (HeLa and MCF-7) as compared to the cells expressing less TfR (HEK-293 and 3T3-L1). Combination index (CI) revealed synergistic activity of Tf-Cu NCs and Dox in Tf-Cu NC-Dox NPs. In vivo assessment of the NPs on TfR positive Daltons lymphoma ascites (DLA) bearing mice revealed significant inhibition of tumor growth rendering prolonged survival of the mice.

Abstract
Multidrug resistance (MDR) contributes to failure of chemotherapy. We here show that biodegradable polymeric nanogels are able to overcome MDR via folic acid targeting. The nanogels are based on hydroxyethyl methacrylamide-oligoglycolates-derivatized poly(hydroxyethyl methacrylamide-co-N-(2-azidoethyl)methacrylamide) (p(HEMAm-co-AzEMAm)-Gly-HEMAm), covalently loaded with the chemotherapeutic drug doxorubicin (DOX) and subsequently decorated with a folic acid-PEG conjugate via copper-free click chemistry. pH-Responsive drug release is achieved via the acid-labile hydrazone bond between DOX and the methacrylamide polymeric network. Cellular uptake and cytotoxicity analyses in folate receptor-positive B16F10 melanoma versus folate receptor-negative A549 lung carcinoma cells confirmed specific uptake of the targeted nanogels. Confocal microscopy demonstrated efficient internalization, lysosomal trafficking, drug release and nuclear localization of DOX. We also show that DOX resistance in 4T1 breast cancer cells results in upregulation of the folate receptor, and that folic acid targeted nanogels can be employed to bypass drug efflux pumps, resulting in highly efficient killing of resistant cancer cells. In conclusion, folic acid functionalized nanogels with pH-controlled drug release seem to hold significant potential for treating multidrug resistant malignancies.

Abstract
Early diagnosis of metastatic cancers could greatly limit the number of cancer-associated deaths. Aberrant surface expression of sialic acid (hypersialylation) on tumors correlating with metastatic incidence and its involvement in tumorigenesis and progression is widely reported; hence detection of hypersialylated tumors may be an effective strategy to identify metastatic cancers. We herein report on the application of phenylboronic acid-installed PEGylated gold nanoparticles coupled with Toluidine blue O (T/BA-GNPs) as SERS probes to target surface sialic acid (N-acetylneuraminic acid, Neu5Ac). Strong SERS signals from metastatic cancer cell lines (breast cancer; MDA-MB231 and colon cancer; Colon-26) were observed, contrary to non-metastatic MCF-7 cells (breast cancer). The detected SERS signals from various cancer cell lines correlated with their reported metastatic potential, implying that our T/BA-GNP based SERS system was capable of distinguishing the metastaticity of cells based on the surface Neu5Ac density. T/BA-GNP based SERS system could also significantly differentiate between hypersialylated tumor tissues and healthy tissues with high SERS signal to noise ratio, due to plasmon coupling between the specifically aggregated functionalized GNPs. Furthermore, we also confirmed reduction in SERS signals from MDA-MB231 surface upon treatment with our original reactive oxygen species (ROS)-scavenging polymeric micelle, nitroxide-radical containing nanoparticles (RNPs). The ROS-mediated abrogation of sialylation by impairing the activation of NF-κB-sialyltransferase signaling cascade upon RNP treatment was confirmed by expression studies and the T/BA-GNPs based SERS system. The aforementioned findings thus, establish T/BA-GNPs based SERS as a potential cytodiagnostic system to detect hypersialylated metastatic tumors and RNPs as anti-metastatic cancer drug candidates.

Abstract
Curcumin is a phytochemical with diverse molecular targets and is well known for its anti-tumor potential. However, it has limited application in cancer therapy because curcumin undergoes rapid oxidative degradation at physiological conditions resulting in poor stability and bio-availability. In this study, we were able to suppress curcumin's oxidative degradation by encapsulating it in a nanoparticle that also acts as a radical scavenger. We prepared curcumin-loaded pH-sensitive redox nanoparticles (RNP(N)) by self-assembling amphiphilic block copolymers conjugated with reactive oxygen species (ROS) scavenging nitroxide radicals to ensure the delivery of minimally degraded curcumin to target regions. In vitro analysis confirmed that the entrapment of both curcumin and nitroxide radicals in the hydrophobic core of RNP(N) suppressed curcumin degradation in conditions mimicking the physiological environment. Evaluation of apoptosis-related molecules in the cells, such as ceramides, caspases, apoptosis-inducing factor, and acid ceramidase revealed that curcumin loaded RNP(N) induced strong apoptosis compared to free curcumin. Lastly, intravenous injection of curcumin loaded RNP(N) suppressed tumor growth in vivo, which is due to the increased bio-availability and significant ROS scavenging at tumor sites. These results demonstrated that RNP(N) is a promising drug carrier with unique ROS-scavenging abilities, and it is able to overcome the crucial hurdle of curcumin's limitations to enhance its therapeutic potential.

Abstract
Nanoscale micelles as an effective drug delivery system have attracted increasing interest in malignancy therapy. The present study reported the construction of the cholesterol-enhanced doxorubicin (DOX)-loaded poly(D-lactide)-based micelle (CDM/DOX), poly(L-lactide)-based micelle (CLM/DOX), and stereocomplex micelle (CSCM/DOX) from the equimolar enantiomeric 4-armed poly(ethylene glycol)-polylactide copolymers in aqueous condition. Compared with CDM/DOX and CLM/DOX, CSCM/DOX showed the smallest hydrodynamic size of 96 ± 4.8 nm and the slowest DOX release. The DOX-loaded micelles exhibited a weaker DOX fluorescence inside mouse renal carcinoma cells (i.e., RenCa cells) compared to free DOX·HCl, probably because of a slower DOX release. More importantly, all the DOX-loaded micelles, especially CSCM/DOX, exhibited the excellent antiproliferative efficacy that was equal to or even better than free DOX·HCl toward RenCa cells attributed to their successful internalization. Furthermore, all of the DOX-loaded micelles exhibited the satisfactory hemocompatibility compared to free DOX·HCl, indicating the great potential for systemic chemotherapy through intravenous injection.

Abstract
The acid-sensitive PEGylated doxorubicin (DOX) with exact chemical structure was designed and prepared as a potential tumor intracellular microenvironment-responsive drug delivery system. First, the insensitive succinic anhydride-functionalized DOX (i.e., SAD) and acid-sensitive cis-aconitic anhydride-modified DOX (i.e., CAD) were synthesized through the ring-opening reaction. Subsequently, the insensitive and acid-sensitive PEGylated DOX (i.e., mPEG-SAD and mPEG-CAD) was prepared by the condensation reaction between the terminal hydroxyl group of mPEG and the carboxyl group in SAD and CAD, respectively. The obtained mPEG-SAD and mPEG-CAD could spontaneously self-assemble into micelles in phosphate-buffered saline at pH 7.4 with diameters of about 100 nm. The DOX release of mPEG-CAD micelle could be accelerated by the decrease of pH from 7.4, 6.8, to 5.5 in relation to that of mPEG-SAD micelle. On the other hand, the result of the cellular proliferation inhibition test indicated that mPEG-CAD micelle exhibited favorable antiproliferative activity in vitro. In addition, the selective intratumoral accumulation and antitumor efficacy of mPEG-CAD micelle were significantly better than those of free DOX and mPEG-SAD. More importantly, the prodrug micelles exhibited upregulated security in vivo as compared to free DOX. Overall, the mPEG-CAD micelle with enhanced antitumor efficacy and decreased side effects was a fascinating prospect for the clinical chemotherapy of malignancy.

Abstract
Doxorubicin is a potent chemotherapeutic drug applied in the clinics for the treatment of various human cancers. It is typically administered as the hydrochloride salt or in liposomal forms, which are plagued with severe side effects. In recent years, pH-sensitive polymeric nanoparticles that are capable of retaining drug during circulation while actively releasing it at the tumor site and/or inside the target tumor cells have received an overwhelming interest for tumor-targeting cancer chemotherapy. This smart delivery approach has shown to elegantly resolve the in vivo stability versus intracellular drug release dilemma, as well as stealth versus tumor cell uptake dilemma. In this review, the concept and exciting new advances in pH-sensitive polymeric nanoparticles for doxorubicin delivery are presented and discussed.

Abstract
The main obstacles to cancer therapy are the inability to target cancer cells and the acquired drug resistance after a period of chemotherapy. Reduced drug uptake and DNA repair are the two main mechanisms involved in cisplatin resistance. In the present investigation, canthaplatin, a Pt(iv) pro-drug of cisplatin and a protein phosphatase 2A (PP2A) inhibitor (4-(3-carboxy-7-oxa-bicyclo[2.2.1]heptane-2-carbonyl)piperazine-1-carboxylic acid tert-butyl ester), was designed and delivered using PEG-b-PLGA micelles for combination chemotherapy. Polymer/canthaplatin micelles facilitated the delivery of the drug into cancer cells through endocytosis and diminished DNA repair by PP2A inhibition, resulting in enhanced anti-tumor efficiency and excellent reversal ability of tumor resistance to cisplatin both in vitro and in vivo. Additionally, the polymer/canthaplatin micelles could prolong drug residence in the blood and decrease the side effects when compared to cisplatin.
