Abstract
Background: Combination therapy has attracted tremendous interest for its great potential in treating cancers. Materials & methods: Based on chitosan-coated silver nanotriangles, polyethylene glycol, AS1411 aptamer and doxorubicin, a multifunctional nanocomposite (AS1411-DOX-AgNTs) was constructed and characterized. Then the photothermal properties, ability to target breast cancer cells and anti-breast cancer effect of AS1411-DOX-AgNTs were evaluated. Results: AS1411-DOX-AgNTs were successfully fabricated and showed excellent photothermal conversion efficiency, breast cancer cell and tumor targeting ability. Compared with single treatments, the combination of AS1411-DOX-AgNTs with near-infrared irradiation possessed the strongest anti-breast cancer effect in vitro and in vivo. Conclusion: AS1411-DOX-AgNTs hold great potential in targeted DOX delivery and combined chemo-photothermal therapy for breast cancer.

Abstract
A mixed drug self-delivery system (DSDS) with high drug content (>50%) was developed to regulate pH-triggered drug release, based on two doxorubicin (DOX)-DOX dimmers: D-DOXADH and D-DOXcar conjugated with acid-labile dynamic covalent bonds (hydrazone and carbamate, respectively) and stabilized with PEGylated D-DOXADH (D-DOXADH-PEG). Owing to the different stability of the dynamic covalent bonds in the two dimers and the noncovalent interaction between them, pH-triggered drug release could be easily regulated by adjusting the feeding ratios of the two DOX-DOX dimers in the mixed DSDS. Similar in vitro cellular toxicity was achieved with the mixed DSDS nanoparticles prepared with different feeding ratios. The mixed DSDS nanoparticles had a similar DOX content and diameter but different drug releasing rates. The MTT assays revealed that a high anti-tumor efficacy could be achieved with the slow-release mixed DSDS nanoparticles.

Abstract
Aim: To determine the optimal AS1411 density on polyethylene glycol (PEG)ylated silver nanotriangles (PNTs) for targeting breast cancer cells. Methods: PNTs modified with different AS1411 densities (ANTs) were constructed, characterized and evaluated for their targeting properties in breast cancer cells and a mouse model of breast cancer. Results: AS1411 was successfully conjugated to PNTs. The accumulation and cellular uptake of 10-ANTs were the highest. 10-ANTs plus near-IR laser irradiation displayed the greatest inhibitory effect on cell viability. However, 5-ANTs had the highest accumulation in tumor tissues. When combined with NIR laser, 5-ANTs exhibited the best in vivo photothermal therapy effect. Conclusion: The optimal AS1411 densities at the cellular and animal levels were 10% and 5%, respectively.

Evaluation of poly (lactic-co-glycolic acid) nanoparticles to improve the therapeutic efficacy of paclitaxel in breast cancer. BIOIMPACTS : BI 2022; 12:515-531.

Abstract
Introduction: Paclitaxel (PTX) is a cornerstone in the treatment of breast cancer, the most common type of cancer in women. However, this drug has serious limitations, including lack of tissue-specificity, poor water solubility, and the development of drug resistance. The transport of PTX in a polymeric nanoformulation could overcome these limitations. Methods: In this study, PLGA-PTX nanoparticles (NPs) were assayed in breast cancer cell lines, breast cancer stem cells (CSCs) and multicellular tumor spheroids (MTSs) analyzing cell cycle, cell uptake (Nile Red-NR-) and α-tubulin expression. In addition, PLGA-PTX NPs were tested in vivo using C57BL/6 mice, including a biodistribution assay. Results: PTX-PLGA NPs induced a significant decrease in the PTX IC50 of cancer cell lines (1.31 and 3.03-fold reduction in MDA-MB-231 and E0771 cells, respectively) and CSCs. In addition, MTSs treated with PTX-PLGA exhibited a more disorganized surface and significantly higher cell death rates compared to free PTX (27.9% and 16.3% less in MTSs from MCF-7 and E0771, respectively). PTX-PLGA nanoformulation preserved PTX's mechanism of action and increased its cell internalization. Interestingly, PTX-PLGA NPs not only reduced the tumor volume of treated mice but also increased the antineoplastic drug accumulation in their lungs, liver, and spleen. In addition, mice treated with PTX-loaded NPs showed blood parameters similar to the control mice, in contrast with free PTX. Conclusion: These results suggest that our PTX-PLGA NPs could be a suitable strategy for breast cancer therapy, improving antitumor drug efficiency and reducing systemic toxicity without altering its mechanism of action.

Abstract
As per the WHO, every year around 2.1 million women are detected with breast cancer. It is one of the most invasive cancer in women and second most among all, contributing around 15% of death worldwide. The available anticancer therapies including chemo, radio, and hormone therapy are associated with a high load of reversible and irreversible adverse effects, limited therapeutic efficacy, and low chances of quality survival. To minimize the side effects, improving therapeutic potency and patient compliance promising targeted therapies are highly desirable. In this sequence, various nanocarriers and target modified systems have been explored by researchers throughout the world. Among these chitosan-based nanocarriers offers one of the most interesting, flexible, and biocompatible systems. The unique characteristics of chitosan like surface flexibility, biocompatibility, hydrophilicity, non-toxic and cost-effective behavior assist to overcome the inadequacy of existing therapy. The present review throws light on the successes, failures, and current status of chitosan modified novel techniques for tumor targeting of bioactives. It also emphasizes the molecular classification of breast cancer and current clinical development of novel therapies. The review compiles most relevant works of the past 10 years focusing on the application of chitosan-based nanocarrier against breast cancer.

Abstract
Polyprodrugs, in which drug was used as the structural unit by linking with each other via the dynamic covalent bonds in the main chain, are expected to endow excellent drug delivery performance. Here, acid-triggered degradable diblock polyprodrug, poly(doxorubicin)-polyethylene glycol (PDOX-PEG), was designed with DOX as structural unit alternately linked with acid-labile hydrazone and maleic amide groups, by the polycondensation of DOX-based dimers (D-DOXADH or D-DOXMAH) with PEGylated dimer (DOX-ADH-DOX-PEG) as end capping agent. The optimized PDOX-PEG, which was synthesized with D-DOXADH and the PEGylated dimer at a feeding ratio of 10%, possessed a high Mn of 3.1 × 104 g/mol with a high DOX content of 75.42%. It could easily self-assemble into near spherical nanoparticles with average hydrodynamic diameter of 135 nm. They showed excellent pH-triggered sustained drug release owing to the acid-triggered degradation of the polyprodrug block in the tumor intracellular microenvironment, with low premature drug leakage of 4.39 % within 60 h. The MTT results indicated the enhanced antitumor efficacy of the proposed PDOX-PEG nanoparticles than free DOX. The results demonstrated the promising potential of the proposed acid-triggered degradable diblock PDOX-PEG polyprodrug for tumor treatment.

Abstract
More precise drug release is expected by conjugating the drug structural units in the polyprodrugs with dynamic covalent bonds responding to different stimuli. Here, amphiphilic acid/hypoxia co-triggered degradable diblock polyprodrug was designed via a facile one-pot method with drug content of 78.6% (1.22 mmol/g) and relatively molecular weight of 2.08 × 104, by condensation polymerization of acid-sensitive dimer of doxorubicin (D-DOXADH) with 2-iminothiolane, in presence of PEGylated D-DOXADH as end capping reagent for the PEGylation. Polyprodrug nanoparticles were easily obtained with mean hydrodynamic diameter of 177.6 ± 8.9 nm via self-assembly, which showed excellent acid/hypoxia co-triggered degradation and drug release performance. The ideal tumor selective cytotoxicity and enhanced antitumor efficacy were revealed with the in vitro cellular experiments. Such features make the proposed amphiphilic acid/hypoxia co-triggered degradable diblock polyprodrug a promising candidate for tumor chemotherapy.

Oral peptide delivery: challenges and the way ahead. Drug Discov Today 2021; 26:931-950. [PMID: 33444788 DOI: 10.1016/j.drudis.2021.01.001] [Citation(s) in RCA: 37] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Revised: 10/16/2020] [Accepted: 01/06/2021] [Indexed: 12/14/2022]
Abstract
Peptides and proteins have emerged as potential therapeutic agents and, in the search for the best treatment regimen, the oral route has been extensively evaluated because of its non-invasive and safe nature. The physicochemical properties of peptides and proteins along with the hurdles in the gastrointestinal tract (GIT), such as degrading enzymes and permeation barriers, are challenges to their delivery. To address these challenges, several conventional and novel approaches, such as nanocarriers, site-specific and stimuli specific delivery, are being used. In this review, we discuss the challenges to the oral delivery of peptides and the approaches used to tackle these challenges.

Towards improved characterisation of complex polyethylene glycol excipients using supercritical fluid chromatography-evaporative light scattering detection-mass spectrometry and comparison with size exclusion chromatography-triple detection array. J Chromatogr A 2020; 1638:461839.

Abstract
The application of supercritical fluid chromatography (SFC) coupled to an evaporative light scattering detector (ELSD) and mass spectrometer (MS) was evaluated for the characterisation of three analogues of functionalised polyethylene glycol (PEG) 2000 (m-PEG-OH, m-PEG-cm and cm-PEG-cm (where m = OCH3 and cm = OCH2COOH)). These polymers are common excipients in drug product formulations for pharmaceuticals as they help provide the desired pharmacokinetic profile for successful drug delivery. A SFC-ELSD-MS method was developed which was selective to all three polymers, and allowed visualisation of these low UV chromophore materials. The method provided baseline resolution of the individual oligomers which allowed facile calculation of the polymer dispersity. A number of molecular weight characteristics were calculated, which showed the SFC-ELSD-MS methodology to be comparable with the current standard of analysis using size exclusion chromatography (SEC) with a triple detector array (TDA). The increased resolving power of SFC compared to SEC revealed a bimodal distribution of oligomers in the cm-PEG-cm 2000 polymer, which was not observed using SEC-TDA and exemplified SFC-ELSD as an orthogonal approach for polymer characterisation with the potential for much simpler, reduced sample and instrument preparation, calibration-less dispersity determination. When combined with SEC-TDA data, this combination allows a more complete characterisation of complex formulations excipients.

Abstract
Carbon dots (CDs) have attracted intense attention in tumor nanotheranostics recently; however, those nanotheranostics exhibited similar fluorescence in both normal and tumor tissues, limiting their practical application. In the present work, absolutely "off-on" fluorescent CD-based nanotheranostics was designed for tumor intracellular real-time imaging and pH-triggered DOX delivery via both static quenching by the crosslinking of benzaldehyde-containing diblock copolymers and dynamic quenching because of the surrounding conjugated DOX molecules. The proposed PPEGMA42-b-PFPMA122-(CDs)-DOX nanotheranostics did not exhibit fluorescence in a normal physiological medium, while strong fluorescence recovery occurred in the tumor intracellular microenvironment due to pH-triggered disintegration, releasing the CDs and DOX. The pH-triggered DOX release and absolute "off-on" fluorescence make the proposed nanotheranostics promising for tumor-specific pH-triggered DOX delivery and imaging.

Photodynamic cancer therapy enhances accumulation of nanoparticles in tumor-associated myeloid cells. J Control Release 2019; 320:19-31.

Abstract
In cancer treatment, nanomedicines may be employed in an attempt to improve the tumor localization of antineoplastic drugs e.g. immunotherapeutic agents either through passive or active targeting, thereby potentially enhancing therapeutic effect and reducing undesired off-target effects. However, a large number of administrated nanocarriers often fail to reach the tumor area. In the present study, we show that photodynamic therapy (PDT) enhances the tumor accumulation of systemically administered lipid-PEG layer coated poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NP). Intravital microscopy and histological analysis of the tumor area reveal that the tumor vasculature was disrupted after PDT, disturbing blood flow and coinciding with entrapment of nanocarriers in the tumor area. We observed that the nanoparticles accumulating after treatment do not confine to specific locations within the tumor, but rather localize to various cells present throughout the tumor area. Finally, we show by flow cytometry that NP accumulation occurred mostly in immune cells of the myeloid lineage present in the tumor microenvironment (TME) as well as in tumor cells, albeit to a lower extent. These data expose opportunities for combination treatments of clinical PDT with NP-based immunotherapy to modulate the TME and improve antitumor immune responses.

Abstract
Drug content and releasing rate are the main determining factors for the drug delivery systems (DDSs). Here, doxorubicin dimer (D-DOXcar) was synthesized as drug-drug conjugate prodrug with high drug content of 86%, via an acid-triggered hydrolysable carbamate linker. The prodrug nanoparticles (D-DOXcar-NP) with different diameters were prepared as drug self-delivery system (DSDS) for intracellular pH-triggered slow release. They showed size- and concentration-dependent pH-triggered slow DOX release. For the D-DOXcar-sNP with smaller diameter, the cumulative release ratio reached 25.6% at pH 5.0 within 60 h. The MTT results demonstrated that the proposed DSDS showed similar tumor inhibition regardless of carboxylesterases, and an enhanced anti-tumor efficacy on the HepG2 cells in comparison with the free DOX.

Abstract
Polymeric nano-carriers are considered as promising tools in biomedical applications due to multiple attractive characteristics including their low toxicity, high loading capacity, controlled drug release capabilities, and highly tunable chemical properties. Here, a series of pH-sensitive star-shaped copolymers, Ad-P[(EMA-co-MAA)-b-PPEGMA]4, was prepared via electron transfer atom radical polymerization (ARGETE ATRP) and selective hydrolysis. These star-shaped copolymers can be self-assembled into micelles (Dh = 150–160 nm) and their critical micelle concentrations (CMC) were estimated to be 3.9–5.0 mg/L. The pH-sensitiveness of the micelles was evidenced by transmission electron microscopy (TEM) and dynamic light scattering (DLS). The maximal paclitaxel (PTX) loading efficiency (DLC) and entrapment efficiency (EE) were 18.9% and 36%, respectively. In vitro release studies revealed that about 19% of the PTX released at an acidic condition of pH 1.2 over 70 h, whereas more than 70% was released within the same time interval at pH 6.8. In vitro cytotoxicity suggested that the low cytotoxicity of the blank micelles, while the PTX-loaded micelles providing the cytotoxicity close to that of free PTX. These results indicated that this novel pH-sensitive nano-carriers have great potential applications for oral drug-controlled release.

Abstract
Two series of amphiphilic block copolymers with a hybrid linear-dendritic structure are presented. The compounds consisted of a hydrophilic poly (ethylene glycol) (PEG) block and a 2,2'-bis(hydroxymethyl)propionic acid (bis-MPA) dendron functionalized with stearic acid chains that impart a hydrophobic nature to the block. Different self-assembled nanostructures with a hydrophobic interior and a hydrophilic external part were obtained depending on the length of the PEG chain (Mn = 2000 and Mn = 5000) and the generation of the bis-MPA dendron. The materials were characterized by transmission electron microscopy (TEM). The shapes of the aggregates ranged from spherical or cylindrical micelles to flexible bilayers. The hydrophobic core enabled these nanostructures to encapsulate the water-insoluble drug plitidepsin. The efficacy of these new plitidepsin-containing carriers was evaluated in four cancer cell-lines and they showed similar anticancer activity to the current standard drug formulation.
