Carbajo-Gordillo AI, Benito E, Galbis E, Grosso R, Iglesias N, Valencia C, Lucas R, García-Martín MG, de-Paz MV. Simultaneous Formation of Polyhydroxyurethanes and Multicomponent Semi-IPN Hydrogels. Polymers (Basel) 2024; 16:880. [PMID: 38611138 PMCID: PMC11013152 DOI: 10.3390/polym16070880] [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: 02/21/2024] [Revised: 03/16/2024] [Accepted: 03/19/2024] [Indexed: 04/14/2024] Open
Abstract
This study introduces an efficient strategy for synthesizing polyhydroxyurethane-based multicomponent hydrogels with enhanced rheological properties. In a single-step process, 3D materials composed of Polymer 1 (PHU) and Polymer 2 (PVA or gelatin) were produced. Polymer 1, a crosslinked polyhydroxyurethane (PHU), grew within a colloidal solution of Polymer 2, forming an interconnected network. The synthesis of Polymer 1 utilized a Non-Isocyanate Polyurethane (NIPU) methodology based on the aminolysis of bis(cyclic carbonate) (bisCC) monomers derived from 1-thioglycerol and 1,2-dithioglycerol (monomers A and E, respectively). This method, applied for the first time in Semi-Interpenetrating Network (SIPN) formation, demonstrated exceptional orthogonality since the functional groups in Polymer 2 do not interfere with Polymer 1 formation. Optimizing PHU formation involved a 20-trial methodology, identifying influential variables such as polymer concentration, temperature, solvent (an aprotic and a protic solvent), and the organo-catalyst used [a thiourea derivative (TU) and 1,8-diazabicyclo [5.4.0]undec-7-ene (DBU)]. The highest molecular weights were achieved under near-bulk polymerization conditions using TU-protic and DBU-aprotic as catalyst-solvent combinations. Monomer E-based PHU exhibited higher Mw¯ than monomer A-based PHU (34.1 kDa and 16.4 kDa, respectively). Applying the enhanced methodology to prepare 10 multicomponent hydrogels using PVA or gelatin as the polymer scaffold revealed superior rheological properties in PVA-based hydrogels, exhibiting solid-like gel behavior. Incorporating monomer E enhanced mechanical properties and elasticity (with loss tangent values of 0.09 and 0.14). SEM images unveiled distinct microstructures, including a sponge-like pattern in certain PVA-based hydrogels when monomer A was chosen, indicating the formation of highly superporous interpenetrated materials. In summary, this innovative approach presents a versatile methodology for obtaining advanced hydrogel-based systems with potential applications in various biomedical fields.

Abstract
Contemporary synthetic chemistry approaches can be used to yield a range of distinct polymer topologies with precise control. The topology of a polymer strongly influences its self-assembly into complex nanostructures however a clear mechanistic understanding of the relationship between polymer topology and self-assembly has not yet been developed. In this work, we use atomistic molecular dynamics simulations to provide a nanoscale picture of the self-assembly of three poly(ethylene oxide)-poly(methyl acrylate) block copolymers with different topologies into micelles. We find that the topology affects the ability of the micelle to form a compact hydrophobic core, which directly affects its stability. Also, we apply unsupervised machine learning techniques to show that the topology of a polymer affects its ability to take a conformation in response to the local environment within the micelles. This work provides foundations for the rational design of polymer nanostructures based on their underlying topology.

Abstract
The synthesis of cyclic amphiphilic graft copolymers with a hydrophobic polycarbonate backbone and hydrophilic poly(N-acryloylmorpholine) (PNAM) side arms via a combination of ring-opening polymerization (ROP), cyclization via copper-catalyzed azide-alkyne cycloaddition (CuAAC), and reversible addition-fragmentation chain transfer (RAFT) polymerization is reported. The ability of these cyclic graft copolymers to form unimolecular micelles in water is explored using a combination of light scattering, small-angle X-ray scattering (SAXS), and cryogenic transmission electron microscopy (cryoTEM) analyses, where particle size was found to increase with increasing PNAM arm length. Further analysis revealed differences in the solution conformations, loading capabilities, and morphologies of the cyclic graft copolymers in comparison to equivalent linear graft copolymer unimolecular micelle analogues. Furthermore, the cyclic and linear graft copolymers were found to exhibit significantly different cloud point temperatures. This study highlights how subtle changes in polymer architecture (linear graft copolymer versus cyclic graft copolymer) can dramatically influence a polymer's nanostructure and its properties.

Abstract
In this paper, we first synthesized a novel disulfide-coupled bis-(cyclic carbonate) (TDCSS) monomer. After ring-opening co-polymerization (ROP) of TDCSS and trimethylene carbonate (TMC) initiated by mono-methoxyl poly(ethylene glycol), the crosslinked reduction-sensitive copolymer PEG-P(TMC-co-TDCSS) was obtained via a facile one-step procedure for efficient delivery of doxorubicin (DOX) into cancer cells. To serve as controls, PEG-P(TMC-co-TDCCC), which has an analogous structure without disulfide bond, and a linear polymer PEG-PTMC were also prepared. The copolymers could self-assemble to form nano-sized micelles in an aqueous solution. As compared to PEG-PTMC, crosslinked PEG-P(TMC-co-TDCSS) and PEG-P(TMC-co-TDCCC) showed lower CMC values and thus induced a much better micelle-forming ability. In vitro release studies revealed that the drug release behavior of DOX-loaded PEG-P(TMC-co-TDCSS) micelles, which could be accelerated in the presence of 10 mM dithiothreitol (DTT), showed a similar trend in the absence of DTT compared to DOX-loaded PEG-P(TMC-co-TDCCC) micelles. Furthermore, confocal laser scanning microscopy (CLSM) indicated that DOX-loaded PEG-P(TMC-co-TDCSS) micelles were efficiently internalized into HeLa cells, releasing DOX into the cytoplasm after which the drug finally entered the nuclei, while MTT assays also demonstrated potent cytotoxic activity against HeLa cells. DOX was mainly located in the cytoplasm for reduction-insensitive PEG-P(TMC-co-TDCCC) and PEG-PTMC controls.

Abstract
Biomaterials scientists strive to develop polymeric materials with distinct chemical make-up, complex molecular architectures, robust mechanical properties and defined biological functions by drawing inspirations from biological systems. Salient features of biological designs include (1) repetitive presentation of basic motifs; and (2) efficient integration of diverse building blocks. Thus, an appealing approach to biomaterials synthesis is to combine synthetic and natural building blocks in a modular fashion employing novel chemical methods. Over the past decade, orthogonal chemistries have become powerful enabling tools for the modular synthesis of advanced biomaterials. These reactions require building blocks with complementary functionalities, occur under mild conditions in the presence of biological molecules and living cells and proceed with high yield and exceptional selectivity. These chemistries have facilitated the construction of complex polymers and networks in a step-growth fashion, allowing facile modulation of materials properties by simple variations of the building blocks. In this review, we first summarize features of several types of orthogonal chemistries. We then discuss recent progress in the synthesis of step growth linear polymers, dendrimers and networks that find application in drug delivery, 3D cell culture and tissue engineering. Overall, orthogonal reactions and modulular synthesis have not only minimized the steps needed for the desired chemical transformations but also maximized the diversity and functionality of the final products. The modular nature of the design, combined with the potential synergistic effect of the hybrid system, will likely result in novel hydrogel matrices with robust structures and defined functions.

Abstract
BACKGROUND Melittin is a commonly used cell-penetrating peptide (CPP) for improving branched polyethylenimine (BPEI)-mediated gene transfection. However, its application is limited owing to the cytotoxicity generated by the lytic activity at neutral pH. In the present study, we report two truncated peptides from melittin and florae with improved transfection efficiency. METHODS Two truncated peptides consisting of 1-20 residues of melittin (MT20) and florae (FL20) were synthesized. Circular dichroism (CD) spectrometry was used to analyze the secondary structures of the peptides. The membrane-lytic activity of the peptides and their potency in enhancing cellular uptake of calcein were evaluated. The peptides and BPEI mixtures were mixed with plasmid DNA to prepare peptide/BPEI/DNA complexes. The physicochemical characters of complexes were measured and the effect of the peptides on BPEI-mediated transfection was determined. RESULTS CD analysis and structure observation showed that the truncated peptides have α-helical conformation, which was necessary for penetrating activity. The truncated peptides exhibited several advantages than their parent peptides: (i) they showed higher hemolytic potency in acidic pH but lower lytic activity than their parent peptides in neutral pH; (ii) enhanced calcein efficiently release from both early and late endosome; (iii) they did not affect the DNA-binding affinity of BPEI and the physicochemical characteristics of BPEI/DNA complexes. Moreover, the peptides could increase BPEI-mediated transfection efficiency in different cell lines (293FT, B16F10 and CHO-K1) by simply mixing with BPEI, without causing cytotoxicity. CONCLUSIONS The results obtained in the present study indicate that the truncated peptides with higher endosomal disrupting activity were better enhancers for increasing transfection efficiency.

Mechanistic and functional aspects of the interaction of AR-23 with mammalian cell membrane and improvement of branched polyethylenimine-mediated gene transfection. J Gene Med 2013; 15:205-14.

Abstract
BACKGROUND Previous studies have suggested that reducing the positive charge of melittin could increase endosomal release activity and improve branched polyethylenimine (BPEI)-mediated transfection. AR-23 is a melittin-related peptide from Rana tagoi, which shows 81% sequence identity with melittin but has less positively-charged residues than melittin. The present study aimed to investigate the mechanistic and functional aspects of the interaction of AR-23 with mammalian cells and thus improve BPEI-mediated gene transfection. METHODS AR23 and two AR-23 analogs (AR-20 without positively-charged residues and AR-26 with the same positively-charged residues as melittin) were analyzed. Circular dichroism (CD) spectrometry was used to analyze the secondary structures of the peptides. Peptide-induced depolarization of cell membrane, the membrane-lytic activity of the peptides, and their potency with respect to enhancing the cellular uptake of calcein were evaluated. The physicochemical characters of complexes were measured and the effect of the peptides on BPEI-mediated transfection was determined. RESULTS The CD spectra results indicated that a positive charge in AR-23 played a crucial role in maintaining the α-helical conformation, whereas an extra positive charge could not increase α-helical formation. AR-23 displayed a similar depolarization ability to melittin. However, AR-23 showed a lower membrane lytic activity under physiological conditions and a higher lytic activity at endosomal pH than melittin and AR-26, which possess more positive charges. Compared to melittin and AR-26, AR-23, with a higher endosomal escaping activity, resulted in a higher enhancement of BPEI-mediated gene transfection, as well as the maintainance of a lower cytotoxicity. CONCLUSIONS We suggest that AR-23 may be considered as a potential enhancer for improving the transfection efficiency of cationic polymers.

Abstract
To enhance site-specific intracellular delivery against the folate receptor, a drug carrier was designed and synthesized by bioconjugation of folic acid (FA) to β-cyclodextrins (β-CD) through a poly(ethylene glycol) (PEG) spacer from "click chemistry" strategy. The resulted conjugates were confirmed by (1)H NMR and IR spectroscopy. Host-guest interactions between hydrophobic drug and β-CD are capable of entrapping a hydrophobic drug, like 5-Fluorouracil, to form drug-β-CD-PEG-FA nanoparticles (NPs) in aqueous solution. The morphology and size of β-CD-PEG-FA NPs were measured by transmission electron microscopy (TEM) and dynamic light scattering (DLS). The targeting ability of the β-CD-PEG-FA NPs was investigated against two kinds of cell lines (HeLa and A549), which have different amounts of folate receptors on their surface. Confocal image analysis revealed that β-CD-PEG-FA conjugate-assembled nanoparticles exhibited a greater extent of cellular uptake against HeLa cells than A549 cells. This suggests folate-receptor-mediated endocytosis can affect the cellular uptake efficiency of drug-loaded β-CD-PEG-FA NPs. The β-CD-PEG-FA conjugates that are presented may be promising active tumor-targeting carrier candidates via folate mediation.

Abstract
Biodegradability can be incorporated into cationic polymers via use of disulfide linkages that are degraded in the reducing environment of the cell cytosol. In this work, N-(2-hydroxypropyl)methacrylamide (HPMA) and methacrylamido-functionalized oligo-l-lysine peptide monomers with either a non-reducible 6-aminohexanoic acid (AHX) linker or a reducible 3-[(2-aminoethyl)dithiol] propionic acid (AEDP) linker were copolymerized via reversible addition-fragmentation chain transfer (RAFT) polymerization. Both of the copolymers and a 1:1 (w/w) mixture of copolymers with reducible and non-reducible peptides were complexed with DNA to form polyplexes. The polyplexes were tested for salt stability, transfection efficiency, and cytotoxicity. The HPMA-oligolysine copolymer containing the reducible AEDP linkers was less efficient at transfection than the non-reducible polymer and was prone to flocculation in saline and serum-containing conditions, but was also not cytotoxic at charge ratios tested. Optimal transfection efficiency and toxicity were attained with mixed formulation of copolymers. Flow cytometry uptake studies indicated that blocking extracellular thiols did not restore transfection efficiency and that the decreased transfection of the reducible polyplex is therefore not primarily caused by extracellular polymer reduction by free thiols. The decrease in transfection efficiency of the reducible polymers could be partially mitigated by the addition of low concentrations of EDTA to prevent metal-catalyzed oxidation of reduced polymers.
