Synthesis and Characterization of Amphiphilic Diblock Polyphosphoesters Containing Lactic Acid Units for Potential Drug Delivery Applications. Molecules 2023; 28:5243.

Abstract
Multistep one-pot polycondensation reactions synthesized amphiphilic diblock polyphosphoesters containing lactic acid units in the polymer backbone. At the first step was synthesized poly[poly(ethylene glycol) H-phosphonate-b-poly(ethylene glycol)lactate H-phosphonate] was converted through one pot oxidation into poly[alkylpoly(ethylene glycol) phosphate-b-alkylpoly(ethylene glycol)lactate phosphate]s. They were characterized by 1H, 13C {H},31P NMR, and size exclusion chromatography (SEC). The effects of the polymer composition on micelle formation and stability, and micelle size were studied via dynamic light scattering (DLS). The hydrophilic/hydrophobic balance of these polymers can be controlled by changing the chain lengths of hydrophobic alcohols. Drug loading and encapsulation efficiency tests using Sudan III and doxorubicin revealed that hydrophobic substances can be incorporated inside the hydrophobic core of polymer micelles. The micelle size was 72-108 nm when encapsulating Sudan III and 89-116 nm when encapsulating doxorubicin. Loading capacity and encapsulation efficiency depend on the length of alkyl side chains. Changing the alkyl side chain from 8 to 16 carbon atoms increased micelle-encapsulated Sudan III and doxorubicin by 1.6- and 1.1-fold, respectively. The results obtained indicate that these diblock copolymers have the potential as drug carriers.

Abstract
To synthesize new (bio)degradable alternatives to commodity polymers, adapting natural motives can be a promising approach. We present the synthesis and characterization of degradable polyethylene (PE)-like polyphosphoesters, which exhibit increased degradation rates due to an intra-molecular transesterification similar to RNA. An α,ω-diene monomer was synthesized in three steps starting from readily available compounds. By acyclic diene metathesis (ADMET) polymerization, PE-like polymers with molecular weights up to 38 400 g mol-1 were obtained. Post-polymerization functionalization gave fully saturated and semicrystalline polymers with a precise spacing of 20 CH2 groups between each phosphate group carrying an ethoxy hydroxyl side chain. This side chain was capable of intramolecular transesterification with the main-chain similar to RNA-hydrolysis, mimicking the 2'-OH group of ribose. Thermal properties were characterized by differential scanning calorimetry (DSC (T m ca. 85 °C)) and the crystal structure was investigated by wide-angle X-ray scattering (WAXS). Polymer films immersed in aqueous solutions at different pH values proved an accelerated degradation compared to structurally similar polyphosphoesters without pendant ethoxy hydroxyl groups. Polymer degradation proceeded also in artificial seawater (pH = 8), while the polymer was stable at physiological pH of 7.4. The degradation mechanism followed the intra-molecular "RNA-inspired" transesterification which was detected by NMR spectroscopy as well as by monitoring the hydrolysis of a polymer blend of a polyphosphoester without pendant OH-group and the RNA-inspired polymer, proving selective hydrolysis of the latter. This mechanism has been further supported by the DFT calculations. The "RNA-inspired" degradation of polymers could play an important part in accelerating the hydrolysis of polymers and plastics in natural environments, e.g. seawater.

Abstract
Polyvalent interactions mediate the formation of higher-order macromolecular assemblies to improve the sensitivity, specificity, and temporal response of biological signals. In host defense, innate immune pathways recognize danger signals to alert host of insult or foreign invasion, while limiting aberrant activation from auto-immunity and cellular senescence. Of recent attention are the unique higher-order assemblies in the cGAS-STING pathway. Natural stimulation of cGAS enzymes by dsDNA induces phase separation and enzymatic activation for switchlike production of cGAMP. Subsequent binding of cGAMP to STING induces oligomerization of STING molecules, offering a scaffold for kinase assembly and signaling transduction. Additionally, the discovery of PC7A, a synthetic polymer which activates STING through a non-canonical biomolecular condensation, illustrates the engineering design of agonists by polyvalency principles. Herein, we discuss a mechanistic and functional comparison of natural and synthetic agonists to advance our understanding in STING signaling and highlight the principles of polyvalency in innate immune activation. The combination of exogenous cGAMP along with synthetic PC7A stimulation of STING offers a synergistic strategy in spatiotemporal orchestration of the immune milieu for a safe and effective immunotherapy against cancer.

Abstract
It has been shown that the thermodynamics of bicontinuous microemulsions can be tailored via the addition of various different amphiphilic polymers. In this manuscript, we now focus on comb-type polymers consisting of hydrophobic backbones and hydrophilic side chains. The distinct philicity of the backbone and side chains leads to a well-defined segregation into the oil and water domains respectively, as confirmed by contrast variation small-angle neutron scattering experiments. This polymer-microemulsion structure leads to well-described conformational entropies of the polymer fragments (backbone and side chains) that exert pressure on the membrane, which influences the thermodynamics of the overall microemulsion. In the context of the different polymer architectures that have been studied by our group with regards to their phase diagrams and small-angle neutron scattering, the microemulsion thermodynamics of comb polymers can be described in terms of a superposition of the backbone and side chain fragments. The denser or longer the side chain, the stronger the grafting and the more visible the brush effect of the side chains becomes. Possible applications of the comb polymers as switchable additives are discussed. Finally, a balanced philicity of polymers also motivates transmembrane migration in biological systems of the polymers themselves or of polymer-DNA complexes.

Abstract
Biodegradable polymers are of current interest and chemical functionality in such materials is often demanded in advanced biomedical applications. Functional groups often are not tolerated in the polymerization process of ring-opening polymerization (ROP) and therefore protective groups need to be applied. Advantageously, several orthogonally reactive functions are available, which do not demand protection during ROP. We give an insight into available, orthogonally reactive cyclic monomers and the corresponding functional synthetic and biodegradable polymers, obtained from ROP. Functionalities in the monomer are reviewed, which are tolerated by ROP without further protection and allow further post-modification of the corresponding chemically functional polymers after polymerization. Synthetic concepts to these monomers are summarized in detail, preferably using precursor molecules. Post-modification strategies for the reported functionalities are presented and selected applications highlighted.

Abstract
Poly(ethylene sodium phosphate) (PEP·Na) showed excellent cytocompatibility and in vivo bone affinity. Moreover, PEP·Na did not interact with thrombin, which is a coagulation-related protein. Because immobilization of therapeutic agents and imaging probes on PEP·Na is easily performed, PEP·Na is a promising polymer for bone-targeted therapies.

Abstract
The focus of this review is on the class of transiently thermoresponsive polymers. These polymers are thermoresponsive, but gradually lose this property upon chemical transformation - often a hydrolysis reaction - in the polymer side chain or backbone. An overview of the different approaches used for the design of these polymers along with their physicochemical properties is given. Their amphiphilic properties and degradability into fully soluble compounds make this class of responsive polymers attractive for drug delivery and tissue engineering applications. Examples of these are also provided in this review.

Abstract
Polymers with repeating phosphoester linkages in the backbone are biodegradable materials that emerge as a promising class of novel biomaterials, especially in the field of drug delivery systems. In contrast to aliphatic polyesters, the pentavalency of the phosphorus atom offers a large diversity of structures and as a consequence a wide range of properties for these materials. In this paper, it is focused on the synthesis of well-defined polyphosphoesters (PPEs) by organocatalyzed ring-opening polymerization, improving the functionalities by combination with click reactions, degradation of functional PPEs and their cytotoxicity, and inputs for applications in drug delivery.

Abstract
The structure and stability of biomolecules under molecular crowding conditions are of interest because such information clarifies how biomolecules behave under cell-mimicking conditions. The anionic surfaces of chromatin, which is composed of DNA strands and histone complexes, are concentrated in cell nuclei and thus generate a polyanionic crowding environment. In this study, we designed and synthesized an anionic polymer, poly(ethylene sodium phosphate) (PEP·Na), which has a nucleic acid phosphate backbone and created a cell nucleus-like environment. The effects of molecular crowding with PEP·Na on the thermodynamics of DNA duplexes, triplexes, and G-quadruplexes were systematically studied. Thermodynamic analysis demonstrated that PEP·Na significantly stabilized the DNA structures; e.g., a free energy change at 25 °C for duplex formation decreased from -6.6 to -12.8 kcal/mol with 20 wt % PEP·Na. Thermodynamic parameters further indicated that the factors for the stabilization of the DNA structures were dependent on sodium ion concentration. At lower polymer concentrations, the stabilization was attributed to a shielding of the electrostatic repulsion between DNA strands by the sodium ions of PEP·Na. In contrast, at higher polymer concentrations, the DNA structures were entropically stabilized by volume exclusion, which could be enhanced by electrostatic repulsion between phosphate groups in DNA strands and in PEP·Na. Additionally, increasing PEP·Na concentration resulted in increasing enthalpy of the DNA duplex but decreasing enthalpy of DNA G-quadruplex, indicating that the polymers also promoted dehydration of the DNA strands. Thus, polyanionic crowding affects the thermodynamics of DNA structures via the sodium ions, volume exclusion, and hydration. The stabilization of DNA by the cell nucleus-like polyanionic crowding provides new information regarding DNA structures and allows for modeling reactions in cell nuclei.

Abstract
A small difference brings high control: In poly(phosphonate)s a stable carbon-phosphorus linkage attaches a side chain to a degradable poly(phosphoester)-backbone. A novel cyclic phosphonate monomer was developed to generate water-soluble aliphatic poly(ethylene methylphospho-nate)s. The monomer is accessible via a robust three-step protocol that can be easily scaled-up. Polymerization was initiated by a primary alcohol, mediated by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in less than 2 h at 0 °C. The molecular weight distributions were monomodal and very narrow (below 1.1) in all cases and molecular weights up to about 20000 g/mol have been prepared, proving the living nature of this polymerization. The resulting polymers were characterized in detail via NMR spectroscopy, size exclusion chromatography, and differential scanning calorimetry. Also, the reaction kinetics have been evaluated for several monomer/initiator ratios and found to guarantee a living behavior in all cases superior to other poly(phosphate)s reported earlier. The polymers are all highly water-soluble without a lower critical solution temperature and are nontoxic against HeLa cells.

Abstract
Interest in thermoresponsive polymers has steadily grown over many decades, and a great deal of work has been dedicated to developing temperature sensitive macromolecules that can be crafted into new smart materials. However, the overwhelming majority of previously reported temperature-responsive polymers are based on poly(N-isopropylacrylamide) (PNIPAM), despite the fact that a wide range of other thermoresponsive polymers have demonstrated similar promise for the preparation of adaptive materials. Herein, we aim to highlight recent results that involve thermoresponsive systems that have not yet been as fully considered. Many of these (co)polymers represent clear opportunities for advancements in emerging biomedical and materials fields due to their increased biocompatibility and tuneable response. By highlighting recent examples of newly developed thermoresponsive polymer systems, we hope to promote the development of new generations of smart materials.

Abstract
Utilization of polymers as biomaterials has greatly impacted the advancement of modern medicine. Specifically, polymeric biomaterials that are biodegradable provide the significant advantage of being able to be broken down and removed after they have served their function. Applications are wide ranging with degradable polymers being used clinically as surgical sutures and implants. In order to fit functional demand, materials with desired physical, chemical, biological, biomechanical and degradation properties must be selected. Fortunately, a wide range of natural and synthetic degradable polymers has been investigated for biomedical applications with novel materials constantly being developed to meet new challenges. This review summarizes the most recent advances in the field over the past 4 years, specifically highlighting new and interesting discoveries in tissue engineering and drug delivery applications.

Abstract
A water-soluble hyperbranched polyphosphate (HPHEEP) was synthesized through the self-condensation ring-opening polymerization (SCROP) of 2-(2-hydroxyethoxy)ethoxy-2-oxo-1,3,2-dioxaphospholane (HEEP), and its suitability as a drug carrier was then evaluated in vitro. Methyl tetrazolium (MTT) and live/dead staining assays indicated that HPHEEP had excellent biocompatibility against COS-7 cells. The good biodegradability of HPHEEP was observed by NMR analysis, and the degradation products were nontoxic to COS-7 cells. Flow cytometry and confocal laser scanning microscopy analyses suggested that HPHEEP could be easily internalized by vivid cells and preferentially accumulated in the perinuclear region. Furthermore, a hydrophobic anticancer drug, chlorambucil, was used as a model drug and covalently bound to HPHEEP. The chlorambucil dose of the conjugate and free drug required for 50% cellular growth inhibition were 75 and 50 microg/mL, respectively, according to MTT assay against an MCF-7 breast cancer cell line in vitro. This high activity of the conjugate may be attributed to the biodegradability of HPHEEP so as to release the chlorambucil in cells. Therefore, on the basis of its biocompatibility and biodegradability, HPHEEP could provide a charming opportunity to design some excellent drug delivery systems for therapeutic applications.

Abstract
The concept of biodegradable plastics is of considerable interest with respect to solid waste accumulation. Greater efforts have been made in developing degradable biological materials without any environmental pollution to replace oil-based traditional plastics. Among numerous kinds of degradable polymers, polylactic acid sometimes called polylactide, an aliphatic polyester and biocompatible thermoplastic, is currently a most promising and popular material with the brightest development prospect and was considered as the 'green' eco friendly material. Biodegradable plastics like polyglycolic acid, polylactic acid, polycaprolactone, polyhydroxybutyrate, etc. are commercially available for controlled drug releases, implantable composites, bone fixation parts, packaging and paper coatings, sustained release systems for pesticides and fertilizers and compost bags etc. This review will provide information on current PLA market, brief account on recent developments in the synthesis of lactic acid (monomer of PLA) through biological route, PLA synthesis, unique material properties of PLA and modification of those by making copolymers and composites, PLA degradation and its wide spectrum applications.

Abstract
This review provides an outline of the polymeric micro/nanostructured advanced systems that are suited for the controlled and targeted administration of, specifically, nonconventional drugs. The contribution of new trends in drug-delivery technology is focused on two major parts, dealing with brief surveys of: the biodegradable/bioerodible polymeric systems used in the formulation of micro/nanoparticles and techniques used in the preparation of micro/nanoparticles for their biomedical application in cancer treatment specifically, in inflammation pathologies, as oxygen carriers (blood substitutes) and in tissue-engineering practice. A small discussion of the future perspectives of the described systems is also given.

Abstract
Biodegradable highly porous hydrogels composed of poly [2-methacryloyloxyethyl phosphorylcholine (MPC)] cross-linked with polyphosphoesters have been prepared as novel cellular matrices. Well-controlled porous hydrogels were fabricated by using potassium hydrogen carbonate as a porogen salt for forming gas. This process enabled the homogeneous expansion of pores within the polymer hydrogel matrices, leading to well-interconnected high porosity. The mechanical properties of the hydrogels were influenced by the cross-linking density and porous structure. Hydrolysis and enzymatic digestion of the hydrogels were determined under basic conditions. The cross-linking density and porosity influenced the rate of degradation of the hydrogels. Acceleration of the degradation with alkaline phosphatase was also observed. Cultivation of mouse osteoblastic cell (MC3T3-E1) was performed in the highly porous hydrogels and cell viability was well maintained. The rate of cell proliferation also was relatively increased with an increase in the amount of polyphosphoesters in the hydrogel. Basic fibroblast growth factor (bFGF) was physically absorbed by the hydrogels and effectively induced cell proliferation. In conclusion, the porous hydrogels prepared in this study contributed a suitable environment for three-dimensional cell cultivation and may be useful for cell and tissue matrices.

Abstract
Naked plasmid DNA (pDNA)-based gene therapy has low delivery efficiency, and consequently, low therapeutic effect. We present a biodegradable nonionic triblock copolymer, PEG(13)-PLGA(10)-PEG(13), to enhance gene delivery efficiency in skeletal muscle. Effects of PEG(13)-PLGA(10)-PEG(13) on physicochemical properties of pDNA were evaluated by atomic force microscopy (AFM) imaging, gel electrophoresis and zeta-potential analysis. AFM imaging suggested a slightly compacted structure of pDNA when it was mixed with the polymer, while zeta-potential measurement indicated an increased surface potential of negatively charged pDNA. PEG(13)-PLGA(10)-PEG(13) showed a relatively lower toxicity compared to Pluronic P85 in a skeletal muscle cell line. The luciferase expression of pDNA delivered in 0.25% polymer solution was up to three orders of magnitude more than branched polyethylenimine (bPEI(25 k))/pDNA and three times more than that of naked pDNA five days after intramuscular administration. This in vivo gene delivery enhancement was also observed displaying a two-fold higher expression of human vascular endothelial growth factor (VEGF). Based on fluorescence labeled pDNA distribution, it is speculated that the greater diffusivity of PEG(13)-PLGA(10)-PEG(13)/pDNA compared to bPEI(25 k)/pDNA accounts for better transfection efficiency in vivo. To summarize, combining PEG(13)-PLGA(10)-PEG(13) with pDNA possesses the potential to improve gene delivery efficiency in skeletal muscle.
