Pharmaceutics 2023; 15:pharmaceutics15051335. [PMID: 37242579 DOI: 10.3390/pharmaceutics15051335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 04/02/2023] [Accepted: 04/13/2023] [Indexed: 05/28/2023] Open
Abstract
Neutral/negatively charged nanoparticles are beneficial to reduce plasma protein adsorption and prolong their blood circulation time, while positively charged nanoparticles easily transverse the blood vessel endothelium into a tumor and easily penetrate the depth of the tumor via transcytosis. Γ-Glutamyl transpeptidase (GGT) is overexpressed on the external surface of endothelial cells of tumor blood vessels and metabolically active tumor cells. Nanocarriers modified by molecules containing γ-glutamyl moieties (such as glutathione, G-SH) can maintain a neutral/negative charge in the blood, as well as can be easily hydrolyzed by the GGT enzymes to expose the cationic surface at the tumor site, thus achieving good tumor accumulation via charge reversal. In this study, DSPE-PEG2000-GSH (DPG) was synthesized and used as a stabilizer to generate paclitaxel (PTX) nanosuspensions for the treatment of Hela cervical cancer (GGT-positive). The obtained drug-delivery system (PTX-DPG nanoparticles) was 164.6 ± 3.1 nm in diameter with a zeta potential of -9.85 ± 1.03 mV and a high drug-loaded content of 41.45 ± 0.7%. PTX-DPG NPs maintained their negative surface charge in a low concentration of GGT enzyme (0.05 U/mL), whereas they showed a significant charge-reversal property in the high-concentration solution of GGT enzyme (10 U/mL). After intravenous administration, PTX-DPG NPs mainly accumulated more in the tumor than in the liver, achieved good tumor-targetability, and significantly improved anti-tumor efficacy (68.48% vs. 24.07%, tumor inhibition rate, p < 0.05 in contrast to free PTX). This kind of GGT-triggered charge-reversal nanoparticle is promising to be a novel anti-tumor agent for the effective treatment of such GGT-positive cancers as cervical cancer.

Abstract
Chemotherapy drugs have been used for a long time in the treatment of cancer, but serious side effects are caused by the inability of the drug to be solely delivered to the tumor when treating cancer with chemotherapy. Natural products have attracted more and more attention due to the antitumor effect in multiple ways, abundant resources and less side effects. Therefore, the combination of natural active ingredients and chemotherapy drugs may be an effective antitumor strategy, which can inhibit the growth of tumor and multidrug resistance, reduce side effects of chemotherapy drugs. Nano-drug co-delivery system (NDCDS) can play an important role in the combination of natural active ingredients and chemotherapy drugs. This review provides a comprehensive summary of the research status and application prospect of nano-delivery strategies for the combination of natural active ingredients and chemotherapy drugs, aiming to provide a basis for the development of anti-tumor drugs.

Abstract
Breast cancer is the leading cause of cancer death among women and almost all of the breast cancer-caused mortality is related to metastasis. It has been reported that glucocorticoid facilitates the metastasis of breast cancer in mice, and mifepristone can antagonize the effect of glucocorticoid. Paclitaxel is one of the important drugs in the treatment of breast cancer. Mifepristone combined with paclitaxel could be an effective strategy for inhibiting breast cancer metastasis. However, their inherent defects, in terms of short blood circulation half-life and lack of tumor targeting, not only limit their effectiveness but also cause adverse reactions. Therefore, our aim is to explore a novel protocol against breast cancer metastasis, further optimize its therapeutic efficacy by a nanodelivery system, and explore its mechanism. Herein, a paclitaxel-conjugated and mifepristone-loaded hydrogel (PM-nano) was prepared by self-assembly. Its characterizations were studied. The antimetastatic effect was evaluated in vitro and in vivo and its mechanism was also explored by western blot assay. The resultant PM-nano was developed with favorable water solubility and good biocompatibility. Moreover, PM-nano displayed increased cell uptake properties and stimulated drug release in the tumor micro-acidic environment. The PM-nano was more effective in inhibiting the proliferation and metastasis of breast cancer than other groups in vitro and in vivo. The PM-nano might inhibit metastasis through glucocorticoid receptor/receptor tyrosine kinase-like orphan receptor 1 and MMPs. Taken together, PM-nano showed superior antimetastatic effects against breast cancer and excellent biocompatibility in vitro and in vivo, providing a new option for limiting metastasis.

Abstract
Drug delivery to tumor sites using nanotechnology has been demonstrated to overcome the drawbacks of conventional anticancer drugs. Altering the surface shape and geometry of nanocomposites alters their chemical properties, which can confer multiple attributes to nanocarriers for the treatment of cancer and their use as imaging agents for cancer diagnosis. However, heterogeneity and blood flow in human cancer limit the distribution of nanoparticles at the site of tumor tisues. For targeted delivery and controlled release of drug molecules in harsh tumor microenvironments, smart nanocarriers combined with various stimuli-responsive materials have been developed. In this review, we describe nanomaterials for smart anticancer therapy as well as their pharmaceutical aspects including pharmaceutical process, formulation, controlled drug release, drug targetability, and pharmacokinetic or pharmacodynamic profiles of smart nanocarriers. Inorganic or organic-inorganic hybrid nanoplatforms and the electrospinning process have also been briefly described here.

Abstract
Drug delivery empowered with nanotechnology manifests to be a superior therapy to cancer. Electrospun nanofibers cocooning anti-cancerous drugs have shown tremendous cytotoxicity towards various tumor cells, including breast, brain, liver, and lung cancer cells. This pristine drug delivery system, according to literature, desists showing any undesirable effects on other parts of the body and bestows several other benefits. From nature-derived Curcumin to laboratory-made Doxorubicin, literature proclaims many such drugs used in nanofibrous drug delivery. Also, multi-drug delivery has been reported to exhibit enhanced properties. The present review exhibits the unrealized potential of nanofibrous drug delivery in chemotherapy.

Abstract
As a well-known anticancer drug, paclitaxel (PTX), a first-line chemotherapeutic agent, remains unsatisfactory for gastric cancer therapy. It is reported that triptolide (TPL) could enhance the anti-gastric cancer effect of PTX. Considering the poor solubility of both drugs, we developed a red blood cell membrane-biomimetic nanosystem, an emerging tool in drug delivery, to co-load paclitaxel and triptolide (red blood cell membrane coated PTX and TPL co-loaded poly(lactic-co-glycolic acid) [PLGA] nanoparticles, RP(P/T)). The successful preparation was confirmed in terms of particle size, morphology, and surface markers assays. This biomimetic system could prolong circulation and escape immune surveillance. And these properties were verified by stability, in vitro drug release, and cellular uptake assays. Moreover, the MTT and colony formation assays demonstrated the superior anti-proliferation effect of the RP(P/T) to free drugs. The enhanced antitumor effects of RP(P/T) on migration and invasion were also evaluated by wound-healing and transwell assays. Overall, the bionic co-delivery nanoplatform with improved efficacy in vitro is a promising therapy for gastric cancer.

Abstract
Simple Summary Treatment of metastatic triple-negative breast cancer (TNBC) relies on chemotherapy. To improve the efficacy of chemotherapy and avoid systemic toxicity, metronomic chemotherapy using continuous administration of low-dose chemotherapy could be a solution. The paclitaxel-loaded PLGA nanofibers allow for continuous and prolonged drug release, which is compatible with the concept of metronomic chemotherapy. The animal study revealed that the strategy successfully inhibited the growth of the primary tumor and distant metastasis without sarcopenia. These data offer new insights into the role of drug-loaded nanofibers in the treatment of metastatic TNBC. Abstract Triple-negative breast cancer (TNBC) is highly aggressive and responds poorly to conventional chemotherapy. The challenge of TNBC therapy is to maximize the efficacies of conventional chemotherapeutic agents and reduce their toxicities. Metronomic chemotherapy using continuous low-dose chemotherapy has been proposed as a new treatment option, but this approach is limited by the selection of drugs. To improve antitumor therapeutic effects, we developed electrospun paclitaxel-loaded poly-d-l-lactide-co-glycolide (PLGA) nanofibers as a topical implantable delivery device for controlled drug release and site-specific treatment. The subcutaneously implanted paclitaxel-loaded nanofibrous membrane in mice was compatible with the concept of metronomic chemotherapy; it significantly enhanced antitumor activity, inhibited local tumor growth, constrained distant metastasis, and prolonged survival compared with intraperitoneal paclitaxel injection. Furthermore, under paclitaxel-loaded nanofiber treatment, systemic toxicity was low with a persistent increase in lean body weight in mice; in contrast, body weight decreased in other groups. The paclitaxel-loaded nanofibrous membranes provided sustained drug release and site-specific treatment by directly targeting and changing the tumor microenvironment, resulting in low systemic toxicity and a significant improvement in the therapeutic effect and safety compared with conventional chemotherapy. Thus, metronomic chemotherapy with paclitaxel-loaded nanofibrous membranes offers a promising strategy for the treatment of TNBC.

Abstract
In recent years, nanotechnology has made great progress in the development and application of tumor detection, diagnosis, and treatment, and eventually formed a "tumor nanomedicine." The emerging field of "materials." Nanoparticles have attracted much attention because they can overcome physiological barriers, effectively deliver hydrophobic drugs, and specifically target tumor tissues. At present, nanomedicines mainly include lipid nanoparticles, polymer nanoparticles granules, gold nanoparticles, magnetic nanoparticles, mesoporous silica, and other dosage forms. The use of nanomaterials as carriers in the treatment of lung cancer has unique advantages in achieving targeted drug delivery, slow-release drugs, and improvement of poorly soluble drugs and peptide drugs show obvious advantages in terms of bioavailability and reduction of adverse reactions, and have broad research and development prospects. This paper reports a new type of self-assembled Ptx-SA drug-loaded nanometers based on the carrier-free concept fiber, and it was found that the drug-loaded fiber has better cellophilicity, anti-tumor effect in vitro and in vivo than naked drug, and may be mediated by regulating the expression of related proteins. Therefore, the paclitaxel-loaded nano drug delivery system serves as a new type of nano preparation for treating lung cancer is worth further research.

Abstract
BACKGROUND AND AIMS Although several treatment regimens for T-cell acute lymphoblastic leukemia (T-ALL), trouble is still ongoing that relapse of disease after therapies in both pediatric and adult patients. Hence, the demand for new alternative therapeutics that are antiproliferative for cancer cells but do not harm healthy cells in treatments is increasing day by day. This study aimed to investigate whether succinic acid show anti-proliferative and apoptotic effect of on T-ALL cell lines. METHODS Time and dose-dependent effects of succinic acid on T-ALL cell lines were determined by using WST-1, caspase-3/ bicinchoninic acid (BCA), and Annexin V-Fluorescein isothiocyanate (FITC) assays. We included the MRC-5 cell line in our study as a healthy control group. RESULTS Based on our findings, 25 and 50 mmol dosages of succinic acid has shown an apoptotic effect on T-ALL cell lines for 48 h treatment. Also, it has shown that after 48 h exposure of 25 and 50 mmol dosages of succinic acid has no significant cytotoxic effect in healthy MRC-5 cells. Apoptotic activity of succinic acid on CCRF-CEM cell line was caspase-3 dependent but not for MOLT-4. As a consequence, succinic acid was found to effect for T-ALL treatment in vitro and might also enlighten new study fields for different cancer experiments.

Abstract
Paclitaxel (Ptx), a microtubule depolymerization inhibitor, is one of the first-line regimens in lung cancer chemotherapy. However, the poor solubility of Ptx, as well as hypersensitivity of the solvent Cremphor EL, severely limits its clinical application. Here we developed a drug-polymer conjugate of Ptx-SA-PEG, in which amphiphilic copolymers poly(ethylene glycol) (PEG) and Ptx were conjugated by succinic acid (SA). The Ptx-SA-PEG polymers self-assemble into nanoparticles (Ptx-NPs) for efficient delivery of Ptx; cell count kit-8 assay and clonogenic assay were used to analyze the antitumor effect of Ptx-NPs. Acridine orange/ethidium bromide double staining, apoptosis analysis and western blot were measured to explore the apoptotic cell death after Ptx-NPs or free Ptx treatment. Subcutaneous xenograft models were practiced to estimate its tumor cytotoxicity and nonspecific side effects in vivo. Immunohistochemistry was used to analyze the effects of apoptosis and proliferation in tumor tissue; in vitro studies demonstrated that Ptx-NPs treatment exhibited more tumor inhibitory activity compared with free Ptx, especially at the lower doses. Moreover, Ptx-NPs activated apoptotic proteins. Animal experiments showed Ptx-NPs induced less weight loss and organ damage than free Ptx. Moreover, tumor growth was slower after Ptx-NPs treatment, indicating the superior antitumor effect and slight side effect of Ptx-NPs over free Ptx. Conjugation of Ptx-SA-PEG provides a feasible way to acquire self-assembled supramolecular Ptx-loaded nanoparticles with higher drug loading efficiency, less non-specific toxicity and more stable and durable antitumor effect of Ptx, providing a potential strategy to meliorate its clinical therapeutic efficacy.

Abstract
Paclitaxel (Ptx), a type of microtubule depolymerization inhibitor, is one of the main components in gastric cancer chemotherapy. Some studies have demonstrated that tetrandrine (Tet), a bisbenzylisoquinoline alkaloid, has potential antitumor effects in several cancers. Aside from the direct anticancer effect, Tet is proved to synergistically enhance the antitumor effect of Ptx in gastric cancer. However, the application of the combinational strategy is limited by the poor solubility of both drugs. Nanodrug delivery systems including polymeric nanoparticles, self-assembled nanofibers, hydrogels, etc., hold the potential to meet the need. Here, a novel supramolecular nanomaterial, based on the concept of "carrier-free nanodrugs", is reported as a feasible platform for synergistic drug delivery. Ptx-SA-RGD is obtained through the conjugation of Ptx and the tumor-specific peptide RGD (arginine-glycine-aspartic acid) with succinic acid (SA) as a linker. Ptx-SA-RGD could self-assemble into Ptx nanofibers (P-NFs) with high drug-loading efficiency. Tet was then encapsulated into P-NFs to acquire novel Ptx and Tet coloaded self-assembled nanofibers (P/T-NFs). The uptake study shows the dynamic internalization of P/T-NFs by the gastric cancer cell line MGC-803. P/T-NFs significantly triggered the accumulation of reactive oxygen species (ROS) in gastric cancer cells MGC803 and further decreased the mitochondrial membrane potential, which led to the induction of mitochondrial apoptosis with superior cytotoxicity against free drugs. Moreover, P/T-NFs suppressed the expressions of p-STAT3 and p-JAK, initiated cytochrome-C release, and promoted caspase protein expression. Furthermore, P/T-NFs demonstrated the strongest tumor-delaying effect as well as the lowest toxicity. Therefore, self-assembled nanofibers of P/T-NFs demonstrated an increase of the mitochondrial apoptosis level and a stronger antitumor effect both in vitro and in vivo, which could be a potential way to enhance the clinical efficacy and reduce the side-effects of Ptx in gastric cancer.

Abstract
The limitations of conventional therapeutic drugs necessitate the importance of developing novel therapeutics to treat diverse diseases. Conventional drugs have poor blood circulation time and are not stable or compatible with the biological system. Nanomaterials, with their exceptional structural properties, have gained significance as promising materials for the development of novel therapeutics. Nanofibers with unique physiochemical and biological properties have gained significant attention in the field of health care and biomedical research. The choice of a wide variety of materials for nanofiber fabrication, along with the release of therapeutic payload in sustained and controlled release patterns, make nanofibers an ideal material for drug delivery research. Electrospinning is the conventional method for fabricating nanofibers with different morphologies and is often used for the mass production of nanofibers. This review highlights the recent advancements in the use of nanofibers for the delivery of therapeutic drugs, nucleic acids and growth factors. A detailed mechanism for fabricating different types of nanofiber produced from electrospinning, and factors influencing nanofiber generation, are discussed. The insights from this review can provide a thorough understanding of the precise selection of materials used for fabricating nanofibers for specific therapeutic applications and also the importance of nanofibers for drug delivery applications.

Abstract
OBJECTIVES Paclitaxel (Ptx) has been regarded as one of the most effective chemotherapeutic drugs for lung cancers. Increasing studies focused on the nano-delivery system of Ptx due to its poor solubility and hypersensitivity. The aim of the recent study was to investigate the antitumor effects of self-assembled Ptx nano-filaments for lung cancer cells. METHODS In the present study, we designed and synthesized novel Ptx-loaded nano-filaments through conjugation of Ptx and succinic acid (SA) (Ptx-SA, P-NFs). Non-small cell lung cancer (NSCLC) A549 and H460 cells were used for detecting the antitumor effects of P-NFs, including cytotoxicity, apoptosis, and migration. Western blotting was performed for analyzing mechanism. RESULTS P-NFs nano-filaments exerted superior antitumor effects against NSCLC cells compared with free Ptx using cytotoxicity tests. Furthermore, P-NFs nano-filaments were much more effective in inducing NSCLC cells apoptosis and inhibiting A549 cells migration than free Ptx. To elucidate the underlying mechanisms, the expression of apoptotic and endoplasmic reticulum (ER) stress proteins was detected. The results indicated that P-NFs nano-filaments enhanced the expression of bax/bcl-2, protein kinase RNA-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme 1α (IRE1α), phospho- c-Jun N-terminal kinase (p-JNK), and C/EPB homologous protein (CHOP), which suggested that the strong antitumor effect of P-NFs nano-filaments may be partially attributed to the activation ER stress. CONCLUSION The current work demonstrated that P-NFs nano-filaments showed superior cytotoxicity of lung cancer cells, highlighting a novel profile of nano-filaments delivery systems as potential strategies for facilitating the therapeutic efficacy of Ptx in lung cancer treatment.

Abstract
A new tumor-targeted drug-loading material, the amphiphilic peptide DGRGGGAAAA (P10) was designed and synthesized, and its self-assembly behavior, drug-loading effects and in vitro characteristics were studied. P10 was synthesized by solid-state synthesis and doxorubicin (DOX) was loaded via dialysis. P10 and DOX were mixed with a mass ratio of 6:1 to form regular round spheres. The interconnection between groups was analyzed spectroscopically and the sphere morphology was studied with SEM and a zeta particle size analyzer. Fluorescence spectroscopy was used to analyze the ability of P10 to form micelles and the efficiency of micelle entrapment, and the drug-loading ratio and drug release characteristics were detected. Finally, the in vitro antitumor activity of P10 was studied with HeLa cells as a model. The results showed that P10's critical micelle concentration (CMC) value and its average grain diameter were approximately 0.045 mg/L and 500 nm. The micelle entrapment ratio and drug-loading ratio were 23.011 ± 2.88 and 10.125 ± 2.62%, respectively, and the in vitro drug-releasing properties of P10 were described by the Zero-order model and the Ritger-Peppas model. Compared with DOX, P10-DOX had a higher tumor cell inhibition ratio and a dose-effect relationship with concentration. When P10-DOX's concentration was 20 μg/mL, the inhibition ratio was 44.17%. The new amphiphilic peptide designed and prepared in this study could be a tumor-targeted drug-loading material with better prospects for application. In this paper, a new tumor-targeted drug-loading material, the amphiphilic peptide DGRGGGAAAA (P10) is designed and synthesized, and its self-assembly behavior, drug-loading effects and in vitro characteristics are studied, providing a theoretical basis and design ideas for further studies and the development of targeted drug-loading materials on tumor cells.
