Evaluation of Antibacterial Activity against Nosocomial Pathogens of an Enzymatically Derived α-Aminophosphonates Possessing Coumarin Scaffold. Int J Mol Sci 2023; 24:14886. [PMID: 37834334 PMCID: PMC10574003 DOI: 10.3390/ijms241914886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 09/30/2023] [Accepted: 10/02/2023] [Indexed: 10/15/2023] Open
Abstract
The purpose of the present study was to evaluate the synergistic effect of two important pharmacophores, coumarin and α-amino dimethyl phosphonate moieties, on antimicrobial activity against selected strains of multidrug-resistant nosocomial pathogenic bacteria. The previously developed enzyme-catalysed Kabachnik-Fields protocol allowed us to obtain the studied compounds with high yields which were free from metal impurities. The structure-activity relationship revealed that inhibitory activity is strongly related to the presence of the trifluoromethyl group (CF3-) in the coumarin scaffold. MIC and MBC studies carried out on six selected pathogenic bacterial strains (Gram-positive pathogenic Staphylococcus aureus (ATCC 23235) strain, as well as on Gram-negative Acinetobacter baumannii (ATCC 17978), Pseudomonas aeruginosa (ATCC 15442), Enterobacter cloacae (ATCC 49141), Porphyromonas gingivalis (ATCC 33277), and Treponema denticola (ATCC 35405)) have shown that tested compounds show a strong bactericidal effect at low concentrations. Among all agents investigated, five exhibit higher antimicrobial activity than those observed for commonly used antibiotics. It should be noted that all the compounds tested showed very high activity against S. aureus, which is the main source of nosocomial infections that cause numerous fatalities. Furthermore, we have shown that the studied coumarin-based α-aminophosphonates, depending on their structural characteristics, are non-selective and act efficiently against various Gram-positive and Gram-negative pathogens, which is of great importance for hospitalised patients.

Redox-responsive carrier based on fluorinated gemini amphiphilic polymer for combinational cancer therapy. Colloids Surf B Biointerfaces 2022; 216:112551.

Abstract
Polymeric micelle has emerged as an efficient implement to overcome the shortcomings of conventional cancer chemotherapy due to its superior solubility of hydrophobic drugs and less side effects of drugs. However, insufficient dilution resistance and ordinary therapeutic effect severely restrict the further translation of current drug-loaded polymeric micelles. Here, we showed that well-defined G-Fn (n = 5, 9, 13) polymeric micelles possessed excellent capabilities as a drug carrier in light of high drug loading content, high stability and precise drug release combined with wonderful endocytosis efficiency to tumors. The representative G-F13 exhibited an excellent dilution resistance, outstanding high drug loading content (22 wt%) and drug loading efficiency (82%), which might be attributed to the extremely low critical micelle concentration conferred by its special Gemini structure and the superhydrophobicity of the fluorocarbon chain. Furthermore, the "cross-linked" internal fluoride membrane consisted of the two chains of the Gemini structure made G-F13 stable even after 24 h of incubation in 10% fetal bovine serum (FBS). The camptothecin (CPT) release was selectively triggered by glutathione (GSH) and H2O2, reaching 75% and 85% after 24 h respectively, in which only 15% of drugs leak under physiological conditions. The CCK-8 assays of Hela cells showed that CPT-loaded G-F13 micelles had high cell compatibility (200 μg/mL, 93% cell viability, 48 h) and high cancer cytotoxicity (IC50 0.1 μg/mL). Notably, a tenfold lower dosage of loaded CPT had an higher tumor growth inhibition than the free CPT. This result was attributed to the combined treatment of fluorinated drug carriers were more likely to penetrate the cell membrane to enter tumor cells, the cytotoxicity of selenic acid generated after the oxidation of G-F13 and the large amounts of CPT after redox release. Excellent physical and chemical properties as well as good therapeutic effects reveal that G-F13 can act as a promising drug carrier to widely use in cancer chemotherapy.

Abstract
The applications of fluorinated molecules in bioengineering and nanotechnology are expanding rapidly with the controlled introduction of fluorine being broadly studied due to the unique properties of C-F bonds. This review will focus on the design and utility of C-F containing materials in imaging, therapeutics, and environmental applications with a central theme being the importance of controlling fluorine-fluorine interactions and understanding how such interactions impact biological behavior. Low natural abundance of fluorine is shown to provide sensitivity and background advantages for imaging and detection of a variety of diseases with 19F magnetic resonance imaging, 18F positron emission tomography and ultrasound discussed as illustrative examples. The presence of C-F bonds can also be used to tailor membrane permeability and pharmacokinetic properties of drugs and delivery agents for enhanced cell uptake and therapeutics. A key message of this review is that while the promise of C-F containing materials is significant, a subset of highly fluorinated compounds such as per- and polyfluoroalkyl substances (PFAS), have been identified as posing a potential risk to human health. The unique properties of the C-F bond and the significant potential for fluorine-fluorine interactions in PFAS structures necessitate the development of new strategies for facile and efficient environmental removal and remediation. Recent progress in the development of fluorine-containing compounds as molecular imaging and therapeutic agents will be reviewed and their design features contrasted with environmental and health risks for PFAS systems. Finally, present challenges and future directions in the exploitation of the biological aspects of fluorinated systems will be described.

Abstract
TPGS approved by FDA can be used as a P-gp inhibitor to effectively reverse multi-drug resistance (MDR) and as an anticancer agent for synergistic antitumor effects. However, the comparatively high critical micelle concentration (CMC), low drug loading (DL) and poor tumor target limit its further clinical application. To overcome these drawbacks, the pH-sensitive star-shaped TPGS copolymers were successfully constructed via using pentaerythritol as the initial materials, ortho esters as the pH-triggered linkages and TPGS active-ester as the terminated MDR material. The amphiphilic star-shaped TPGS copolymers could self-assemble into free and doxorubicin (DOX)-loaded micelles at neutral aqueous solutions. The micelles exhibited the lower CMC (8.2 × 10−5 mg/ml), higher DL (10.8%) and long-term storage and circulation stability, and showed enhanced cellular uptake, apoptosis, cytotoxicity, and growth inhibition for in vitro MCF-7/ADR and/or MCF-7/ADR multicellular spheroids and in vivo MCF-7/ADR tumors via efficiently targeted drug release at tumoral intracellular pH (5.0), MDR reversal of TPGS, and synergistic effect of DOX and TPGS. Therefore, the pH-sensitive micelles self-assembled from star-shaped TPGS copolymers with ortho ester linkages are potentially useful to clinically transform for enhanced MDR cancer treatment.

Abstract
To promote the highly selective synergistic chemotherapy, the pH-ultra-sensitive dynamic methotrexate nano-prodrugs with detachable PEGylation were successfully prepared via facile method, and the synergistic nanodrugs could be further constructed through encapsulating Doxorubicin (DOX) following the self-assembly process. The nano-prodrugs exhibited the low critical micelle concentration (CMC), negative zeta potential and stability for 5 days in PBS and FBS at physiological pH (7.4) for stable blood circulation, DePEGylation and dynamic size change at tumoral extracellular pH (6.8) for improved tumor accumulation and cellular internalization, and efficiently synergistic drug release at tumoral intracellular pH (5.0) for enhanced tumor apoptosis and cytotoxicity. Moreover, in vivo experiment suggested that the synergistic nanodrugs could significantly improve tumor accumulation and restrain tumor growth while decreasing adverse effects. Therefore, the dynamic methotrexate nano-prodrugs with detachable PEGylation are easy to clinically transform for highly selective synergistic chemotherapy.

Abstract
PURPOSE For patients with intractable cancer-related pain, administration of strong opioid analgesics and adjuvant agents by the intrathecal (i.t.) route in close proximity to the target receptors/ion channels, may restore pain relief. Hence, the aim of this study was to use bioerodable polymers to encapsulate an opioid analgesic (hydromorphone) and an adjuvant drug (ketamine) to produce prolonged-release formulations for i.t. injection. METHODS A two-stage microfluidic method was used to fabricate nanoparticles (NPs). The physical properties were characterised using dynamic light scattering and transmission electron microscopy. A pilot in vivo study was conducted in a rat model of peripheral neuropathic pain. RESULTS The in vitro release of encapsulated payload from NPs produced with a polymer mixture (CPP-SA/PLGA 50:50) was sustained for 28 days. In a pilot in vivo study, analgesia was maintained over a three day period following i.t. injection of hydromorphone-loaded NPs at 50 μg. Co-administration of ketamine-loaded NPs at 340 μg did not increase the duration of analgesia significantly. CONCLUSIONS The two-stage microfluidic method allowed efficient production of analgesic/adjuvant drug-loaded NPs. Our proof-of-principle in vivo study shows prolonged hydromorphone analgesic for 78 h after single i.t. injection. At the i.t. dose administered, ketamine released from NPs was insufficient to augment hydromorphone analgesia.

Abstract
Incorporation of fluorinated moieties in polymeric nanoparticles has been shown in many instances to increase their uptake by living cells and, hence, has proven to be a useful approach to enhancing delivery to cells. However, it remains unclear how incorporation of fluorine affects critical transport processes, such as interactions with membranes, intracellular transport, and tumor penetration. In this study, we investigate the influence of fluorine on transport properties using a series of rationally designed poly(oligo(ethylene glycol) methyl ether acrylate)-block-perfluoropolyether (poly(OEGA)m-PFPE) copolymers. Copolymers with different fluorine contents were prepared and exhibit aggregate in solution in a manner dependent on the fluorine content. Doxorubicin-conjugated poly(OEGA)20-PFPE nanoparticles with lower fluorine content exist in solution as unimers, leading to greater exposure of hydrophobic PFPE segments to the cell surface. This, in turn, results in greater cellular uptake, deeper tumor penetration, as well as enhanced therapeutic efficacy compared to that with the micelle-state nanoaggregates (poly(OEGA)10-PFPE and poly(OEGA)5-PFPE) with higher fluorine content but with less PFPE exposed to the cell membranes. Our results demonstrate that the aggregation behavior of these fluorinated polymers plays a critical role in internalization and transport in living cells and 3D spheroids, providing important design criteria for the preparation of highly effective delivery agents.

Abstract
To promote the targeted cancer therapy, the pH-sensitive small molecule nanodrug self-assembled from amphiphilic vitamin B6-E analogue conjugate was successfully constructed. Herein, water-soluble vitamin B6 with pKa (5.6) was chemically conjugated to lipid-soluble vitamin E succinate (α-TOS), which showed selective cancer cell killing ability and this amphiphilic small molecule vitamin conjugate could self-assemble to be free nanoparticles (NPs) and doxorubicin-loaded NPs (α-TOS-B6-NPs-DOX). The small molecule nanodrugs could perform the following characteristic: (i) stability in the sodium dodecyl sulfonate (SDS) solution and long-term storage stability in PBS via surface negative charge; (ii) tumor accumulation by enhanced penetration and retention (EPR) effect; (iii) improved cellular internalization by means of vitamin B6 transporting membrane carrier (VTC); and (iv) facilitating endosomal escape and rapid drug release for synergistic toxicity to tumor cells via charge reversal and ester hydrolysis at intracellular pH and/or esterase. Moreover, α-TOS-B6-NPs-DOX exhibited long blood circulation stability and significant tumor accumulation and inhibition with the decreased side effects in vivo. Thus, the pH-sensitive small molecule nanodrug self-assembled from amphiphilic vitamin B6-E analogue conjugate could be the potential drug carriers in targeted synergistic cancer therapy.

Abstract
Although surface PEGylation of nanomedicines can decrease serum protein adsorption in vivo, it also blocks uptake by tumor cells. This dilemma could be overcome by employing detachably PEGylated strategy at tumoral extracellular microenvironment to achieve improved cellular uptake while prolonged circulation times. Herein, the amphiphilic graft copolymers with pH-sensitive ortho ester-linked mPEG in side chains and polyurethanes in backbone, can self-assemble into the free and doxorubicin (DOX)-loaded micelles. The pH-sensitive micelles could undergo several characteristics as follows: (i) PEGylated shells for stability in sodium dodecyl sulfonate (SDS) solution; (ii) DePEGylation via degradation of ortho ester linkages at tumoral extracellular pH (6.5) for gradually dynamic size changes and effective release of DOX; and (iii) enhanced cellular uptake and cytotoxicity via positive DOX. Moreover, the dynamic micelles with detachable PEGylation could quickly penetrate the centers of SH-SY5Y multicellular spheroids (MCs) and strongly inhibit tumor growth in vitro and in vivo, and might be considered as promising and effective drug carriers in tumor therapy.

Abstract
To promote chemotherapeutic efficacy and easier clinical transformation, a series of pH-sensitive and dynamic drug delivery systems with facile two-step synthesis and simple structure have been successfully constructed by the tunable grafting reaction between pH-sensitive ortho ester and poly(vinyl alcohol). The amphipathic graft macromolecules (PVA- g-OE x, x represents the percentage of feed between ortho esters and hydroxyl groups of polyvinyl alcohol) could self-assemble into micelles and doxorubicin was embedded. These micelles exhibited pH-sensitivity to both extracellular and intracellular pH and demonstrated the following characteristics: (i) maintaining long-term storage and blood circulation stability at pH 7.4; (ii) responding to tumoral extracellular pH value following gradually larger nanoparticles for improved drug accumulation and retention; (iii) being sensitive to tumoral intracellular pH value following disintegration for rapid drug release to improve toxicity to tumor cells. Moreover, the doxorubicin-loaded micelle (PVA- g-OE30-DOX) showed similar cytotoxicity to free doxorubicin in vitro, but stronger tumor penetration and inhibition ability in vitro human liver carcinoma cell line multicellular tumor spheroids. In vivo biodistribution and tumor inhibition examinations demonstrated that PVA- g-OE30-DOX had more superior efficacy in significantly enhancing drug accumulation in tumor, restraining tumor growth while decreasing drug concentration in normal tissues. The pH-sensitive, dynamic graft polymer micelles via simple synthesis could be considered as a promising and effective drug carrier in tumor therapy.

Abstract
To achieve enhanced cancer therapy, a sequentially dynamic polymeric drug delivery system (ortho ester-linked PEGylated poly(disulfide)s-based micelle-doxorubicin (PS-g-OEMPEG-DOX)) is successfully constructed. The PEGylated micelle can keep stable in sodium dodecyl sulfate (SDS) solution at pH 7.4, but be prone to DePEGylation and dynamic size changes via the hydrolysis of ortho ester linkages in side chains at tumoral extracellular pH value (6.5). Moreover, the micelle can rapidly release DOX via the cleavage of poly(disulfide)s in backbone at intracellular reductive milieu (10 mmol/L of dithiothreitol (DTT)). The dynamic micelle with detachable PEGylation achieves the stable blood circulation, improved cellular uptake and cytotoxicity, stronger in vitro penetration and inhibition of tumoral multicellular spheroids, and significant in vivo tumor accumulation and inhibition while decreasing side effects. Thus, the sequentially dynamic polymeric micelle with detachable PEGylation can be considered as a promising and effective drug delivery system in cancer therapy.

Abstract
It remains a crucial challenge to achieve efficient cellular uptake in tumor cells for nanoscale drug delivery systems. This work described that two multi-functional pullulan nanogels were prepared by co-polymerization between methacrylated pullulan (Pullulan-M) and different crosslink agents, an acid-labile ortho ester-modified pluronic (L61-MOE) or non-acid-sensitive methacrylated pluronic (L61-M). The prepared nanogels showed a regular spherical structure with the size about 200 nm measured by dynamic light scattering and transmission electron microscopy (TEM). Doxorubicin as a model drug was successfully encapsulated into nanogels. As expected, Pul-L61-MOE showed pH-dependent DOX release, and 25% of DOX was released at pH 7.4 while 84.48% of DOX was released at pH 5.0. In vitro cellular uptake and MTT results indicated that pH-sensitive nanogels (Pul-L61-MOE) displayed higher cellular internalization and cytotoxicity than acid-insensitive nanogels (Pul-L61-M) and free DOX. Flow cytometry assay suggested these nanogels remarkably increased intracellular reactive oxygen species (ROS) level and induced more cell apoptosis by the function of pluronic. Finally, in vivo antitumor results indicated that the multi-functional nanogels exhibit supreme antitumor efficiency, and the tumor growth inhibition (TGI) was 83.37%. Therefore, the pH-sensitive pullulan nanogels can be potential nano-carriers for drug delivery in tumor treatment.

Abstract
To achieve precise control of nano-carrier structure and drug release behavior, we designed a pH/redox dual-responsive polymeric prodrug by condensation polymerization using octahedrally coordinated cisplatin (Pt IV) and ortho ester monomer. The prodrug was then self-assembled with doxorubicin (DOX) in aqueous solution to give a synergetic drug delivery system. The polymer backbone can completely degrade and release cisplatin (Pt II) and DOX under the acidic and reductive environment of tumor cells, owing to the breakage of ortho ester bonds and the reduction of Pt (IV). The size and micromorphology of micelles were observed by dynamic light scattering (DLS) and transmission electron microscopy (TEM). In vitro study of drug release, cellular uptake and cytotoxicity revealed that the micelles could be triggered intracellularly to release two drugs. In vivo drug distribution and antitumor activity also provide the evidence for the excellent antitumor effect of micelles.

Abstract
Herein pH-sensitive nanogels (NG1) and P-glycoprotein-repressive nanogels (NG2) were prepared by copolymerization between an ortho ester crosslinker (OEAM) and tocopheryl polyethylene glycol succinate (TPGS)-free or conjugated dextran. Nanogels with or without TPGS possessed a uniform diameter (∼180 nm) and excellent stability in various physiological environments. Doxorubicin (DOX) was successfully loaded into NG1 and NG2 to give NG1/DOX and NG2/DOX, both of them showed appropriate drug release profiles under mildly acidic conditions (pH 5.0). NG2/DOX possessed higher drug enrichment and lethality than NG1/DOX did on MCF-7/ADR cells. Analysis of corresponding index of efflux activity showed that NG2 could induce depolarization of mitochondrial membrane and interfere with ATP metabolism. NG2/DOX also displayed increased penetration and growth inhibition on MCF-7/ADR multicellular spheroids. These results demonstrated that pH-sensitive TPGS-functionalized nanogels (NG2) as drug carriers had great potential to suppress drug efflux in MCF-7/ADR cells and even overcome MDR on cancer cells.
