Abstract
Background Subcellular organelle targeted nano-formulations for cancer treatment are receiving increasing attention owing to their benefits of precise drug delivery, maximized therapeutic index, and reduced off-target side effects. The nucleus and mitochondria, as the main subcellular organelles, are the significant organelles responsible for maintaining cell operation and metabolism. They can be involved in many essential physiological and pathological processes such as cell proliferation, organism metabolism, intracellular transportation, and play a critical role in regulating cell biology. Meanwhile, breast cancer metastasis is one of the leading causes of death in breast cancer patients. With the development of nanotechnology, nanomaterials have been widely used in tumor therapy. Methods We designed a subcellular organelle targeted nanostructured lipid carriers (NLC) to deliver paclitaxel (PTX) and gambogic acid (GA) to tumor tissues. Results Due to the surface of NLC being modified by subcellular organelle targeted peptide, the PTX and GA co-loaded NLC can accurately release PTX and GA in tumor cells. This property makes NLC able to easy to enter tumor site and target the specific subcellular organelle. The modified NLC can efficiently inhibit the growth of 4T1 primary tumor and lung metastasis, which may be related to the down-regulation of matrix metalloproteinase-9 (MMP-9) and BCL-2 levels, up-regulation of E-cadherin level, and antagonized PTX-induced increase of C-C chemokine ligand 2 (CCL-2) levels by GA. Meanwhile, the synergistic anti-tumor effect of GA and PTX has also been verified in vitro and in vivo experiments. Conclusion The subcellular organelle targeted peptide modified PTX+GA multifunctional nano-drug delivery system has a good therapeutic effect on tumors, and this study provides significant insights into the role of different subcellular organelles in inhibiting tumor growth and metastasis and inspires researchers to develop highly effective cancer therapeutic strategies through subcellular organelle targeted drugs.

Int J Mol Sci 2022; 23:7495.

Abstract
Because the combination of π-conjugated polymers with biocompatible synthetic counterparts leads to the development of bio-relevant functional materials, this paper reports a new oligo(2-methyl-2-oxazoline) (OMeOx)-containing thiophene macromonomer, denoted Th-OMeOx. It can be used as a reactive precursor for synthesis of a polymerizable 2,2'-3-OMeOx-substituted bithiophene by Suzuki coupling. Also a grafted polythiophene amphiphile with OMeOx side chains was synthesized by its self-acid-assisted polymerization (SAAP) in bulk. The results showed that Th-OMeOx is not only a reactive intermediate but also a versatile functional material in itself. This is due to the presence of 2-bromo-substituted thiophene and ω-hydroxyl functional end-groups, and due to the multiple functionalities encoded in its structure (photosensitivity, water self-dispersibility, self-assembling capacity). Thus, analysis of its behavior in solvents of different selectivities revealed that Th-OMeOx forms self-assembled structures (micelles or vesicles) by "direct dissolution".Unexpectedly, by exciting the Th-OMeOx micelles formed in water with λabs of the OMeOx repeating units, the intensity of fluorescence emission varied in a concentration-dependent manner.These self-assembled structures showed excitation-dependent luminescence as well. Attributed to the clusteroluminescence phenomenon due to the aggregation and through space interactions of electron-rich groups in non-conjugated, non-aromatic OMeOx, this behavior certifies that polypeptides mimic the character of Th-OMeOx as a non-conventional intrinsic luminescent material.

Abstract
Ferroptosis is a novel type of regulated cell death characterized by the accumulation of lipid peroxides to lethal levels. Most tumor cells are extremely vulnerable to ferroptosis due to the high levels of reactive oxygen species (ROS) produced by their active metabolism. Therefore, tumor cells rely on glutathione (GSH) to reduce lipid peroxides catalyzed by glutathione peroxidase 4 (GPX4), and this pathway is also an important target for a variety of drugs that promote tumor cell ferroptosis. Herein, RSL3@PCA was designed to simultaneously deplete intracellular GSH and inhibit the activity of GPX4, thereby significantly promoting tumor cell ferroptosis. RSL3@PCA was successfully prepared by encapsulating a selective inhibitor of GPX4 into acid-responsive nanoparticle PCA. After being taken up by tumor cells, the acid-responsive nanoparticle gradually degraded to release cinnamaldehyde (CA) and the encapsulated RSL3. CA and RSL3 block the reduction of lipid peroxides in cells, thereby inducing ferroptosis. By a cytotoxicity assay and 4T1 cell xenotransplantation model, we confirmed that RSL3@PCA has excellent inhibition of tumor growth without significant toxicity to normal cells and tissues and still has a good therapeutic effect on tumor cells that are resistant to conventional chemotherapy drugs. This work provides new drug combinations for promoting ferroptosis in tumor cells without severe side effects in normal organs.

Efficient drug delivery and anticancer effect of micelles based on vitamin E succinate and chitosan derivatives. Bioact Mater 2021; 6:3025-3035. [PMID: 33778185 PMCID: PMC7960945 DOI: 10.1016/j.bioactmat.2021.02.028] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 02/09/2021] [Accepted: 02/21/2021] [Indexed: 12/26/2022] Open
Abstract
Nanocarriers have emerged as a promising cancer drug delivery strategy. Multi-drug resistance caused by overexpression of multiple-drug excretion transporters in tumor cells is the major obstacle to successful chemotherapy. Vitamin E derivatives have many essential functions for drug delivery applications, such as biological components that are hydrophobic, stable, water-soluble enhancing compounds, and anticancer activity. In addition, vitamin E derivatives are also effective mitocan which can overcome multi-drug resistance by binding to P glycoproteins. Here, we developed a carboxymethyl chitosan/vitamin E succinate nano-micellar system (O-CMCTS-VES). The synthesized polymers were characterized by Fourier Transform IR, and 1H NMR spectra. The mean sizes of O-CMCTS-VES and DOX-loaded nanoparticles were around 177 nm and 208 nm. The drug loading contents were 6.1%, 13.0% and 10.6% with the weight ratio of DOX to O-CMCTS-VES corresponding 1:10, 2:10 and 3:10, and the corresponding EEs were 64.3%, 74.5% and 39.7%. Cytotoxicity test, hemolysis test and histocompatibility test showed that it had good biocompatibility in vitro and in vivo. Drug release experiments implied good pH sensitivity and sustained-release effect. The DOX/O-CMCTS-VES nanoparticles can be efficiently taken up by HepG2 cancer cells and the tumor inhibition rate is up to 62.57%. In the in vivo study by using H22 cells implanted Balb/C mice, DOX/O-CMCTS-VES reduced the tumor volume and weight efficiently with a TIR of 35.58%. The newly developed polymeric micelles could successfully be utilized as a nanocarrier system for hydrophobic chemotherapeutic agents for the treatment of solid tumors. A nano-micellar system (O-CMCTS-VES) constituted by carboxymethyl chitosan and vitamin E succinate was fabricated. The micelles hold high cytocompatibility, hemocompatibility, tissue compatibility, and drug load contents. Drug release experiments implied good pH sensitivity and sustained-release effect of O-CMCTS-VES. O-CMCTS-VES loading DOX showed efficient anti-tumor effect in vitro and in vivo.

Abstract
Here we presented a novel micelle self-assembled from amphiphiles with π-conjugated moieties (OEG-DPH). The π-conjugated structural integrity of the micelles enabled stable encapsulation of Nile Red (NR, model drug). The self-assembly behaviour of the amphiphiles and the release profile of NR loaded micelles were investigated. Spherical core-shell structured NR loaded micelles with low CMC of 57 μg/mL and the efficient intracellular delivery process was monitored. This research provided a way to fabricate stable polymeric micelles and develop a practical nanocarrier for therapeutics delivery.

Abstract
Simultaneous delivery of small molecules and nucleic acids using a single vehicle can lead to novel combination treatments and multifunctional carriers for a variety of diseases. In this study, we report a novel library of aminoglycoside-derived lipopolymers nanoparticles (LPNs) for the simultaneous delivery of different molecular cargoes including nucleic acids and small-molecules. The LPN library was screened for transgene expression efficacy following delivery of plasmid DNA, and lead LPNs that showed high transgene expression efficacies were characterized using hydrodynamic size, zeta potential, 1H NMR and FT-IR spectroscopy, and transmission electron microscopy. LPNs demonstrated significantly higher efficacies for transgene expression than 25 kDa polyethyleneamine (PEI) and lipofectamine, including in presence of serum. Self-assembly of these cationic lipopolymers into nanoparticles also facilitated the delivery of small molecule drugs (e.g. doxorubicin) to cancer cells. LPNs were also employed for the simultaneous delivery of the small-molecule histone deacetylase (HDAC) inhibitor AR-42 together with plasmid DNA to cancer cells as a combination treatment approach for enhancing transgene expression. Taken together, our results indicate that aminoglycoside-derived LPNs are attractive vehicles for simultaneous delivery of imaging agents or chemotherapeutic drugs together with nucleic acids for different applications in medicine and biotechnology.

Abstract
Challenges associated with low-drug-loading capacity, lack of active targeting of tumor cells and unspecific drug release of nanocarriers synchronously plague the success of cancer therapy. Herein, we constructed active-targeting, redox-activated polymeric micelles (HPGssML) self-assembled aptamer-decorated, amphiphilic biodegradable poly (benzyl malolactonate-co-ε-caprolactone) copolymer with disulfide linkage and π-conjugated moieties. HPGssML with a homogenous spherical shape and nanosized diameter (∼150 nm) formed a low critical micellar concentration (10−3 mg/mL), suggesting good stability of polymeric micelles. The anticancer drug, doxorubicin (DOX), can be efficiently loaded into the core of micelles with high-drug-loading content via strong π–π interaction, which was verified by a decrease in fluorescence intensity and redshift in UV adsorption of DOX in micelles. The redox sensitivity of polymeric micelles was confirmed by size change and in vitro drug release in a reducing environment. Confocal microscopy and flow cytometry assay demonstrated that conjugating aptamers could enhance specific uptake of HPGssML by cancer cells. An in vitro cytotoxicity study showed that the half-maximal inhibitory concentration (IC50) of DOX-loaded HPGssML was two times lower than that of the control group, demonstrating improved antitumor efficacy. Therefore, the multifunctional biodegradable polymeric micelles can be exploited as a desirable drug carrier for effective cancer treatment.

Abstract
In this work, we presented ternary nanoparticles [poly(carboxybetaine methacrylate) (pCBMA)(peptide dendrimer-modified carbon dots (CD-D)/doxorubicin (DOX))] based on peptide dendritic carbon dots (CDs) to realize tumor-specific drug delivery and highly efficient cancer therapy. The versatile nanoparticles could achieve "stealth" delivery in blood due to the antifouling zwitterion coating. Meanwhile, charge changes of the zwitterions could be moderated during their transportation toward/inside tumor cells, where subtle environmental pH variations acted as potent stimuli to actualize desired functions. In particular, the detachment of the zwitterionic "coat" at the tumor site resulted in the exposure of abundant peripheral guanidine groups on peptide dendritic carbon dots (CD-D/DOX) owing to the extracellular pH environment (pH 6.8)-induced charge conversion. Consequently, the positively charged CD-D/DOX (+7.02 mV) interacted with the negatively charged cancer cell membrane to enhance cellular uptake. After endocytosis, tumor intracellular microenvironments (acidic conditions and high glutathione (GSH) levels) could lead to effective disintegration of the CD-D/DOX entities due to acid-induced protonation of guanidine groups and glutathione-induced cleavage of peptide dendritic components on CDs, and then effective endosomal escape and fast doxorubicin hydrochloride (DOX·HCl) release (73.2% accumulative release within 4 h) were achieved successively. This strategy enabled a 9.19-fold drug release rate at tumor sites in comparison with the one in the physiological environment. Moreover, the excellent fluorescence properties of CDs endowed the pCBMA(CD-D/DOX) with fluorescence bioimaging function. In view of the above-mentioned advantages, pCBMA(CD-D/DOX) exhibited outstanding antitumor activities both in vitro and in vivo, demonstrating much higher antitumor efficacy and less side effects than the free DOX·HCl.

Abstract
In traditional nano drug-delivery systems, the complex chemical bonds between drug and carrier often complicate the preparation process and are less prone to rupture upon entry into the target, which is detrimental to the timely release of the drug. The π-π stacking provides us with a promising alternative as it is a weak interaction between the aromatic rings. Since most antitumor drugs are hydrophobic molecules with complex aromatic π-π-conjugated structures, the construction of self-assembly based on π-π stacking between drugs and carriers has the advantage of improving the stability and drug loading capacity as well as the improvement of hydrophilicity and biosafety. This article introduces the recent advances in π-π stacking-guided nano self-assembly for antineoplastic delivery.

Abstract
In this study, a novel supramolecular hydrogel, abbreviated as AGC16/NTS, was designed and constructed by the molecular self-assembly of a cationic gemini surfactant, 1,3-bis(N,N-dimethyl-N-cetylammonium)-2-propylacrylatedibromide (AGC16), and an anionic aromatic gelator, trisodium 1,3,6-naphthalenetrisulfonate (NTS). The AGC16/NTS hydrogel was able to form in a mass ratio range of AGC16 and NTS from 20 : 1 to 10 : 1. It was interestingly found that AGC16/NTS exhibited two phase transitions (gel-to-gel and gel-to-sol) observed by visual and rheological measurements during the heating process, which is rarely reported in the previous literature reports of hydrogels prepared using low molecular weight gelators. Cryogenic scanning electron microscopy (cryo-SEM), fluorescence emission spectroscopy and X-ray diffraction (XRD) were used to investigate the temperature-responsive properties and molecular self-assembly mechanism of the hydrogel AGC16/NTS. During the gel-to-gel transition process, the temperature-responsive changes in the visual appearance of AGC16/NTS (turbid to transparent) were clearly observed. Compared with the transparent gel, the turbid gel possesses higher mechanical strength and a much more compact network mophology due to stronger intermolecular hydrophobic association beetween gelators. The molecular self-assembly modes for the two different hydrogel states (turbid and transparent gel) were proposed, helping to further understand the hydrogel transition mechanisms at a molecular level.

Abstract
Low drug loading and instability in blood circulation are two key challenges that impede the successful clinical translation of nanomedicine, as they result in only marginal therapeutic efficacy and toxic side effects associated with premature drug leakage, respectively. Herein, highly stable and ultrahigh drug loading micellar nanocomplexes (MNCs) based on the self-assembly of the anticancer drug doxorubicin (DOX) and a poly(ethylene glycol)-epigallocatechin-3-O-gallate (EGCG) conjugate are developed. The formation of these MNCs is facilitated by strong favorable intermolecular interactions between the structurally similar aromatic EGCG and DOX molecules, which impart exceptionally high drug-loading capability of up to 88% and excellent thermodynamic and kinetic stability. Unlike two clinical formulations of DOX-free DOX and liposomal DOX, which are not effective below their lethal dosages, these DOX-loaded MNCs demonstrate significant tumor growth inhibition in vivo on a human liver cancer xenograft mouse model with minimal unwanted toxicity. Overall, these MNCs can represent a safe and effective strategy to deliver DOX for cancer therapy.

Abstract
The development of effective drug carriers can lead to improved outcomes in a variety of disease conditions. Aminoglycosides have been used as antibacterial therapeutics, and are attractive as monomers for the development of polymeric materials in various applications. Here, we describe the development of novel aminoglycoside-derived amphiphilic nanoparticles for drug delivery, with an eye towards ablation of cancer cells. The aminoglycoside paromomycin was first cross-linked with resorcinol diglycidyl ether leading to the formation of a poly (amino ether), PAE. PAE molecules were further derivatized with methoxy-terminated poly(ethylene glycol) or mPEG resulting in the formation of mPEG-PAE polymer, which self-assembled to form nanoparticles. Formation of the mPEG-PAE amphiphile was characterized using (1)H NMR, (13)C NMR, gel permeation chromatography (GPC) and FTIR spectroscopy. Self-assembly of the polymer into nanoparticles was characterized using dynamic light scattering, zeta potential analyses, atomic force microscopy (AFM) and the pyrene fluorescence assay. mPEG-PAE nanoparticles were able to carry significant amounts of doxorubicin (DOX), presumably by means of hydrophobic interactions between the drug and the core. Cell-based studies indicated that mPEG-PAE nanoparticles, loaded with doxorubicin, were able to induce significant loss in viabilities of PC3 human prostate cancer, MDA-MB-231 human breast cancer, and MB49 murine bladder cancer cells; empty nanoparticles resulted in negligible losses of cell viability under the conditions investigated. Taken together, our results indicate that the mPEG-PAE nanoparticle platform is attractive for drug delivery in different applications, including cancer.

Abstract
In this work, we report dual cellular environmental stimuli-responsive hydrogel nanocapsules (HA-NCs) for delivery of an anticancer drug (doxorubicin, DOX). This nanocapsule drug delivery system was specially designed to be triggered by stimuli in intra-cellular environments, specifically high glutathione (GSH) concentration and low pH. Biocompatible hyaluronan was used as the basic nanocapsule shell building material. Chemical modifications were conducted in order to functionalize it; specifically, GSH cleavable crosslinking sites and pH responsive expansion sites were introduced. After passive delivery to tumor sites via an enhanced permeation and retention (EPR) effect and cellular uptake, the nanocapsule shells underwent a swelling/disassembly process due to high GSH concentration (e.g., 10 mM), which induced cleavage of disulfide (S-S) bonds, and low pH (e.g., pH 5), which caused water influx associated with deprotection of the acetal groups. This process enabled rupture of the hydrogel nanocapsules and therefore resulted in release of the encapsulated payloads. This hydrogel nanocapsule system exhibited a great ability to release the vast majority of the encapsulated DOX in tumor cells, as proven by the remarkably (4.7-fold) accelerated drug release rate within tumor cells (pH 5.0, GSH 10 mM), in sharp contrast to the drug release rate under physiological conditions (pH 7.4, GSH 0). In vitro bio-evaluation showed the good biocompatibility of the nanocapsule carriers and their efficient cancer cell growth inhibition activity after drug encapsulation. In vivo studies confirmed that the DOX containing nanocapsules (DOX/HA-NCs) had comparable antitumor efficiency and greatly reduced side effects as compared with free DOX (DOX·HCl).

Abstract
High drug loading content is the critical factor to polymeric micelles for efficient chemotherapy. Small molecules of cinnamic acid, 7-carboxymethoxy coumarin and chrysin with different π-conjugated moieties were immobilized on the terminal hydroxyl groups of PCL segments in mPEG-PCL micelles to improve drug loading content via the evocation of π-π stacking interaction between doxorubicin (DOX) and polymeric micelles. The modification of π-conjugated moieties enhanced the capability of crystallization of mPEG-PCL block copolymers. The drug loading content increased dramatically from 12.9% to 25.5% after modification. All the three modified mPEG-PCL micelles were nontoxic to cells. Chrysin modified polymeric micelles exhibited the most efficient anticancer activity. The in vivo anticancer activity of 10 mg/kg DOX dose of chrysin modified micelle formulation for twice injections was comparable to that of 5 mg/kg dose of free DOX·HCl for four injections under the circumstance of same total DOX amount. The systemic toxicity of DOX loaded chrysin modified micelles was significantly reduced. This research provided a facile strategy to achieve polymeric micelles with high drug loading content and efficient anticancer activity both in vitro and in vivo.

Abstract
The multi-modal combination therapy is proved powerful and successful to enhance the antitumor efficacy in clinics as compared with single therapy modes. In this study, the potential of combining chemotherapy with antiangiogenic therapy for the treatment of non-small-cell lung cancer is explored. Towards this aim, OEGylated carboxymethyl cellulose-(2-(2-(2-methoxyethoxy)ethoxy)methyl)oxirane (CMC-ME2MO) is prepared by treating CMC with ME2MO in the alkaline aqueous solution, and used to efficiently carry doxorubicin (DOX) with high drug-loading content (16.64%) and encapsulation efficiency (99.78%). As compared to free DOX, the resulting nanoparticles show not only the favorable stability in vitro but also the prolonged blood circulation, improved safety and tolerability, optimized biodistribution, reduced systemic toxicity, and enhanced antitumor efficacy in vivo, indicates a potential utility in cancer chemotherapy. Furthermore, the combination of the DOX-loaded polysaccharide nanoparticles and antiangiogenic drug endostar provides synergistic effects of chemotherapy and antiangiogenic therapy, which shows the highest efficiency in tumor suppression. The combination approach of the DOX-containing nanomedicine and endostar for efficient treatment of non-small-cell lung cancer is first proposed to demonstrate the synergistic therapeutic effect. This synergistic combination proves to be a promising therapeutic regimen in cancer therapy and holds great potential for clinical application.
