Abstract
Stimuli-responsive amphiphilic polymers are known to be precursors to forming promising nanoarchitectonics with tunable properties for application in biomedical sciences. Currently, self-immolative polymers are widely recognized as an emerging class of responsive materials with excellent degradability, which is one of the crucial criteria for designing a robust drug delivery vehicle. Here, we design an amphiphilic polyurethane endowed with a redox-responsive self-immolative linker and a pH-responsive tertiary amine on the backbone, which forms entropy-driven nanoscale supramolecular assemblies (average hydrodynamic diameter ∼110 nm) and is programmed to disassemble in a redox environment (GSH) due to the degradation of the polymer in a self-immolative fashion. The nanoassembly shows efficient drug sequestration and release in a controlled manner in response to glutathione (10 mM). The tertiary amine residing on the surface of the nanoassembly becomes protonated in the tumor microenvironment (pH ∼ 6.4-6.8) and generates positively charged nanoassembly (ζ-potential = +36 mV), which enhances the cancer cell-selective cellular uptake. The biological evaluation of the drug-loaded nanoassembly revealed triple-negative breast cancer (MDAMB-231) selective internalization and cell death while shielding normal cells (RBCs or PBMCs) from off-targeting toxicity. We envision that polyurethane with a redox-responsive self-immolative linker might open up new opportunities for a completely degradable polyurethane-based nanocarrier for drug delivery and diagnosis applications.

Tumor-overexpressed enzyme responsive amphiphiles small molecular self-assembly nano-prodrug for the chemo-phototherapy against non-small-cell lung cancer. Mater Today Bio 2023; 21:100722. [PMID: 37545562 PMCID: PMC10401344 DOI: 10.1016/j.mtbio.2023.100722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 06/20/2023] [Accepted: 07/01/2023] [Indexed: 08/08/2023] Open
Abstract
Rational design of self-assembly drug amphiphiles can provide a promising strategy for constructing nano-prodrug with high drug loading, smart stimuli-responsive drug release and high tumor selectivity. Herein, we report a small molecular amphiphile prodrug that can self-assemble into multifunctional nano-prodrug for enhanced anticancer effect by the combination of chemotherapy and phototherapy (PDT/PTT). In this prodrug, the simple insertion of quinone propionate into hydrophilic drug Irinotecan (Ir) generates suitable amphiphiles that endow a good self-assembly behavior of the prodrug and transform it into a stable and uniform nanoparticle. Interestingly, this excellent self-assembly behavior can load phototherapy agent ICG to form a multifunctional nano-prodrug, thereby enhancing the chemotherapeutic effect with PDT/PTT. Importantly, the quinone propionic acid moiety in the prodrug showed a high sensitivity to the overexpressed NAD(P)H:quinone oxidoreductase-1 (NQO1) in non-small cell lung cancer (NSCLC) cells, and this sensitivity enables the disassembly of nano-prodrug and efficient NQO1-responsive drug release. To further enhance the drug accumulation on tumor tissue and migrate the blood clearance, a biomimetic nano-prodrug has been successfully explored by coating hybrid membrane on the above nano-prodrug, which displays high selective inhibition of tumor growth and metastasis on NSCLC mice model. Our findings provide new insights into the rational design of tumor-overexpressed enzyme responsive nano-prodrug for cancer combinational therapy.

Abstract
Background Advanced breast cancer is a highly metastatic tumor with high mortality. Simultaneous elimination of primary tumor and inhibition of neutrophil-circulation tumor cells (CTCs) cluster formation are urgent issues for cancer therapy. Unfortunately, the drug delivery efficiency to tumors and anti-metastasis efficacy of nanomedicine are far from satisfactory. Methods To address these problems, we designed a multi-site attack, neutrophil membrane-camouflaged nanoplatform encapsulating hypoxia-responsive dimeric prodrug hQ-MMAE2 (hQNM-PLGA) for enhanced cancer and anti-metastasis therapy. Results Encouraged by the natural tendency of neutrophils to inflammatory tumor sites, hQNM-PLGA nanoparticles (NPs) could target delivery of drug to tumor, and the acute hypoxic environment of advanced 4T1 breast tumor promoted hQ-MMAE2 degradation to release MMAE, thus eliminating the primary tumor cells to achieve remarkable anticancer efficacy. Alternatively, NM-PLGA NPs inherited the similar adhesion proteins of neutrophils so that NPs could compete with neutrophils to interrupt the formation of neutrophil-CTC clusters, leading to a reduction in extravasation of CTCs and inhibition of tumor metastasis. The in vivo results further revealed that hQNM-PLGA NPs possessed a perfect safety and ability to inhibit tumor growth and spontaneous lung metastasis. Conclusion This study demonstrates the multi-site attack strategy provides a prospective avenue with the potential to improve anticancer and anti-metastasis therapeutic efficacy.

Abstract
This study describes the preparation of hydrogen bonding connected micelles, consisting of a poly(styrene-alt-(para-hydroxyphenylmaleimide)) [poly(S-alt-pHPMI)] core and a poly(4-vinylpyridine) (P4VP) derivative shell in a selective solvent. The aim was to modify hydrogen bonding interaction sites at the core/shell interface by synthesizing P4VP derivatives in three different sequences, namely, P4VP homopolymers, PS-co-P4VP random copolymers, and block copolymers. TEM images showed the successful self-assembly of poly(S-alt-pHPMI)/PS-co-P4VP inter-polymer complexes into spherical structures. To dissolve the core structures, 1,4-dibromobutane was used as a cross-linking agent to tighten the PS-co-P4VP shell. The morphologies, particle sizes, hydrogen bonding, cross-linking reaction, and core dissolution were confirmed by TEM, DLS, FTIR, and AFM analyses. Poly(S-alt-pHPMI)/PS41-r-P4VP59 hydrogen bonding connected micelles, cross-linked micelles, and hollow spheres were larger and more irregular than poly(S-alt-pHPMI)/P4VP inter-polymer complexes due to the random copolymer architecture and the decrease in intermolecular hydrogen bonds. However, poly(S-alt-pHPMI)/PS68-b-P4VP32 resulted in rod- or worm-like structures after core dissolution.

Abstract
Poly(disulfide)s-based systems with repetitive disulfide bonds in their backbones are emerging as promising tumor microenvironment responsive platforms for drug delivery. However, complicated synthesis and purification processes have restricted their further application. Herein, we developed redox-responsive poly(disulfide)s (PBDBM) by one-step oxidation polymerization of a commercially available monomer, 1,4-butanediol bis(thioglycolate) (BDBM). PBDBM can self-assemble with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-poly(ethylene glycol)3400 (DSPE-PEG3.4k) by the nanoprecipitation method and be formulated into PBDBM NPs (sub 100 nm). It can also be loaded with docetaxel (DTX), a first-line chemotherapy agent for breast cancer, to form DTX@PBDBM NPs with a loading capacity of 6.13%. DTX@PBDBM NPs with favorable size stability and redox-responsive capability exhibit superior antitumor activity in vitro. In addition, owing to the different glutathione (GSH) levels in normal and tumor cells, PBDBM NPs with disulfide bonds could synergistically increase intracellular ROS levels, further inducing apoptosis and cell cycle arrest in the G2/M phase. Moreover, in vivo studies revealed that PBDBM NPs could accumulate in tumors, suppress 4T1 tumor growth, and significantly attenuate the systemic toxicity of DTX. Thus, a novel redox-responsive poly(disulfide)s nanocarrier was successfully and facilely developed for cancer drug delivery and effective breast cancer therapy.

Abstract
Ultrasound (US)-triggered therapies are promising in cancer treatments, and their effectiveness can be enhanced through the proper camouflage of sonosensitizers. Herein, we have constructed cancer cell membrane (CCM)-camouflaged sonosensitizers for homotypic tumor-targeted sonodynamic therapy (SDT). The camouflaged sonosensitizers have been prepared by encapsulating hemoporfin molecules in poly(lactic acid) polymers (H@PLA) and extruding with CCM from Colon Tumor 26 (CT26) cells, forming the H@PLA@CCM. Under excitation with US, the hemoporfin encapsulated in H@PLA@CCM can convert O2 into cytotoxic 1O2, which exerts an efficient sonodynamic effect. The H@PLA@CCM nanoparticles show enhanced cellular internalization to CT26 cells compared to H@PLA, and they also can be more efficiently engulfed by CT26 cells than by mouse breast cancer cells, due to the homologous targeting ability of CT26 CCM. After the intravenous injection, the blood circulation half-life of H@PLA@CCM is determined to be 3.23 h which is 4.3-time that of H@PLA. With high biosafety, homogeneous targeting ability, and sonodynamic effect, the combination of H@PLA@CCM and US irradiation has induced significant apoptosis and necrosis of tumor cells through the efficient SDT, achieving the strongest inhibition rate of tumors among other groups. This study provides insights into designing efficient and targeted cancer therapies using CCM-camouflaged sonosensitizers.

Abstract
Chemotherapy is one of the main therapeutic strategies for the treatment of malignant melanoma. Conventional chemotherapeutic agents often lack targeting abilities, and efficacy is hampered by their high toxic effects to normal tissues and rapid clearance from the circulation. In this study, porous paclitaxel (PTX)-loaded polylactide (PLA) microspheres (PPMSs) were prepared by a modified double-emulsion-solvent evaporation method. In addition, PPMSs and cisplatin (DDP) were co-embedded in a thermosensitive hydrogel to construct a dual-drug co-delivery hydrogel system (PPMSs/DDP@Gel) for in-situ chemotherapy to treat melanoma by means of an intra-tumoral injection. The system allows for the sustained release of two drugs and exhibits good temperature-sensitive properties. In vitro antitumor activity showed that this hydrogel composite can induce B16 cell apoptosis and inhibit its migration. In vivo, anti-tumor studies have shown that the PPMSs/DDP@Gel significantly inhibited tumor growth, prolonged the survival of tumor-bearing mice, and had no obvious toxic side effects on major organs. Furthermore, immunohistochemical analysis revealed that PPMSs/DDP@Gel significantly inhibited tumor cell proliferation and promoted apoptosis of tumor cells. Taken together, the injectable temperature-sensitive PPMSs/DDP@Gel is a promising candidate for the local treatment of melanoma.

Abstract
Concurrent developments in anticancer nanotechnological treatments have been observed as the burden of cancer increases every year. The 21st century has seen a transformation in the study of medicine thanks to the advancement in the field of material science and nanomedicine. Improved drug delivery systems with proven efficacy and fewer side effects have been made possible. Nanoformulations with varied functions are being created using lipids, polymers, and inorganic and peptide-based nanomedicines. Therefore, thorough knowledge of these intelligent nanomedicines is crucial for developing very promising drug delivery systems. Polymeric micelles are often simple to make and have high solubilization characteristics; as a result, they seem to be a promising alternative to other nanosystems. Even though recent studies have provided an overview of polymeric micelles, here we included a discussion on the "intelligent" drug delivery from these systems. We also summarized the state-of-the-art and the most recent developments of polymeric micellar systems with respect to cancer treatments. Additionally, we gave significant attention to the clinical translation potential of polymeric micellar systems in the treatment of various cancers.

Abstract
Various formulations of polymeric micelles, tiny spherical structures made of polymeric materials, are currently being investigated in preclinical and clinical settings for their potential as nanomedicines. They target specific tissues and prolong circulation in the body, making them promising cancer treatment options. This review focuses on the different types of polymeric materials available to synthesize micelles, as well as the different ways that micelles can be tailored to be responsive to different stimuli. The selection of stimuli-sensitive polymers used in micelle preparation is based on the specific conditions found in the tumor microenvironment. Additionally, clinical trends in using micelles to treat cancer are presented, including what happens to micelles after they are administered. Finally, various cancer drug delivery applications involving micelles are discussed along with their regulatory aspects and future outlooks. As part of this discussion, we will examine current research and development in this field. The challenges and barriers they may have to overcome before they can be widely adopted in clinics will also be discussed.

Abstract
The overexpression of hypoxia-inducible factor-1 alpha (HIF-1α) in solid tumor compromises the potency of chemotherapy under hypoxia. The high level of HIF-1α arises from the stabilization effect of reduced nicotinamideadeninedinucleotide(phosphate) NAD(P)H: quinone oxidoreductase 1 (NQO1). It was postulated that the inhibition of NQO1 could degrade HIF-1α and sensitize hypoxic cancer cells to antineoplastic agents. In the current work, we report hypoxia-responsive polymer micelles, i.e. methoxyl poly(ethylene glycol)-co-poly(aspartate-nitroimidazole) orchestrate with a NQO1 inhibitor (dicoumarol) to sensitize the ovarian cancer cell line (SKOV3) to a model anticancer agent (sorafenib) at low oxygen conditions. Both cargos were physically encapsulated in the nanoscale micelles. The placebo micelles transiently induced the depletion of reduced nicotinamideadeninedinucleotidephosphate (NADPH) as well as glutathione and thioredoxin under hypoxia, which further inactivated NQO1 because NADPH was the cofactor of NQO1. As a consequence, the expression of HIF-1α was repressed due to the dual action of dicoumarol and polymer. The degradation of HIF-1α significantly increased the vulnerability of SKOV3 cells to sorafenib-induced apoptosis, as indicated by the enhancement of cytotoxicity, and increase of caspase 3 and cytochrome C. The current work opens new avenues of addressing hypoxia-induced drug resistance in chemotherapy.
