Evaluation of Encapsulation Potential of Selected Star-Hyperbranched Polyglycidol Architectures: Predictive Molecular Dynamics Simulations and Experimental Validation. Molecules 2023; 28:7308. [PMID: 37959728 PMCID: PMC10650410 DOI: 10.3390/molecules28217308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 10/14/2023] [Accepted: 10/20/2023] [Indexed: 11/15/2023] Open
Abstract
Polymers, including non-linear copolymers, have great potential in the development of drug delivery systems with many advantages, but the design requires optimizing polymer-drug interactions. Molecular dynamics (MD) simulations can provide insights into polymer-drug interactions for designing delivery systems, but mimicking formulation processes such as drying is often not included in in silico studies. This study demonstrates an MD approach to model drying of systems comprising either hydrophilic tinidazole or hydrophobic clotrimazole drugs with amphiphilic hyperbranched copolyethers. The simulated drying protocol was critical for elucidating drug encapsulation and binding mechanisms. Experimentally, two polymers were synthesized and shown to encapsulate clotrimazole with up to 83% efficiency, guided by interactions with the hydrophobic core observed in simulations. In contrast, tinidazole is associated with surface regions, indicating capacity differences between drug types. Overall, this work highlights MD simulation of the drying process as an important tool for predicting drug-polymer complex behaviour. The modelled formulation protocol enabled high encapsulation efficiency and opened possibilities for the design of delivery systems based on computationally derived binding mechanisms. This demonstrates a computational-experimental approach where simulated drying was integral to elucidating interactions and developing optimized complexes, emphasizing the value of molecular modelling for the development of drug delivery formulations.

Abstract
Bioinks are formulations of biomaterials and living cells, sometimes with growth factors or other biomolecules, while extrusion bioprinting is an emerging technique to apply or deposit these bioinks or biomaterial solutions to create three-dimensional (3D) constructs with architectures and mechanical/biological properties that mimic those of native human tissue or organs. Printed constructs have found wide applications in tissue engineering for repairing or treating tissue/organ injuries, as well as in vitro tissue modelling for testing or validating newly developed therapeutics and vaccines prior to their use in humans. Successful printing of constructs and their subsequent applications rely on the properties of the formulated bioinks, including the rheological, mechanical, and biological properties, as well as the printing process. This article critically reviews the latest developments in bioinks and biomaterial solutions for extrusion bioprinting, focusing on bioink synthesis and characterization, as well as the influence of bioink properties on the printing process. Key issues and challenges are also discussed along with recommendations for future research.

Abstract
Clotrimazole, a hydrophobic drug routinely used in the treatment of vaginal candidiasis, also shows antitumor activity. However, its use in chemotherapy has been unsuccessful to date due to its low solubility in aqueous media. In this work, new unimolecular micelles based on polyether star-hyperbranched carriers of clotrimazole are presented that can enhance solubility, and consequently the bioavailability, of clotrimazole in water. The amphiphilic constructs consisting of a hydrophobic poly(n-alkyl epoxide) core and hydrophilic corona of hyperbranched polyglycidol were synthesized in a three-step anionic ring-opening polymerization of epoxy monomers. The synthesis of such copolymers, however, was only possible by incorporating a linker to facilitate the elongation of the hydrophobic core with glycidol. Unimolecular micelles-clotrimazole formulations displayed significantly increased activity against human cervical cancer HeLa cells compared to the free drug, along with a weak effect on the viability of the normal dermal microvascular endothelium cells HMEC1. This selective activity of clotrimazole on cancer cells with little effect on normal cells was a result of the fact that clotrimazole targets the Warburg effect in cancer cells. Flow cytometric analysis revealed that the encapsulated clotrimazole significantly blocks the progression of the HeLa cycle in the G0/G1 phase and induces apoptosis. In addition, the ability of the synthesized amphiphilic constructs to form a dynamic hydrogel was demonstrated. Such a gel facilitates the delivery of drug-loaded single-molecule micelles to the affected area, where they can form a continuous, self-healing layer.

Abstract
To develop and assess new dosage forms for the alternative to existing oral medication for peripheral neuropathy, a hydrogel film in the skin patch formation containing tramadol hydrochloride (TRA), a water-soluble drug used as an analgesic, was prepared and evaluated. A hydrogel film composed of 20%(w/w) hydroxypropyl methylcellulose (HPMC) irradiated with electron beams had high transparency and elasticity similar to commercially available wound dressings and soft tissues, suggesting that it is a suitable substrate for TRA. The inclusion of TRA was enabled by immersing the HPMC hydrogel film in TRA aqueous solution. The release and skin permeation of TRA from TRA-containing hydrogel films differed depending on the electron beam dose. Moreover, the analgesic effects in mice were confirmed in a dose-dependent manner. This study demonstrated the usefulness of a hydrogel film containing TRA as a new dosage form alternative to the existing oral medication for peripheral neuropathy.

Abstract
![]()
Injectable, self-healing hydrogels with enhanced solubilization
of hydrophobic drugs are urgently needed for antimicrobial intravaginal
therapies. Here, we report the first hydrogel systems constructed
of dynamic boronic esters cross-linking unimolecular micelles, which
are a reservoir of antifungal hydrophobic drug molecules. The selective
hydrophobization of hyperbranched polyglycidol with phenyl units in
the core via ester or urethane bonds enabled the solubilization of
clotrimazole, a water-insoluble drug of broad antifungal properties.
The encapsulation efficiency of clotrimazole increases with the degree
of the HbPGL core modification; however, the encapsulation is more
favorable in the case of urethane derivatives. In addition, the rate
of clotrimazole release was lower from HbPGL hydrophobized via urethane
bonds than with ester linkages. In this work, we also revealed that
the hydrophobization degree of HbPGL significantly influences the
rheological properties of its hydrogels with poly(acrylamide-ran-2-acrylamidephenylboronic acid). The elastic strength
of networks (GN) and the thermal stability
of hydrogels increased along with the degree of HbPGL core hydrophobization.
The degradation of the hydrogel constructed of the neat HbPGL was
observed at approx. 40 °C, whereas the hydrogels constructed
on HbPGL, where the monohydroxyl units were modified above 30 mol
%, were stable above 50 °C. Moreover, the flow and self-healing
ability of hydrogels were gradually decreased due to the reduced dynamics
of macromolecules in the network as an effect of increased hydrophobicity.
The changes in the rheological properties of hydrogels resulted from
the engagement of phenyl units into the intermolecular hydrophobic
interactions, which besides boronic esters constituted additional
cross-links. This study demonstrates that the HbPGL core hydrophobized
with phenyl units at 30 mol % degrees via urethane linkages is optimal
in respect of the drug encapsulation efficiency and rheological properties
including both self-healable and injectable behavior. This work is
important because of a proper selection of a building component for
the construction of a therapeutic hydrogel platform dedicated to the
intravaginal delivery of hydrophobic drugs.

Abstract
Biomimetic hydrogels have emerged as the most useful tissue engineering scaffold materials. Their versatile chemistry can recapitulate multiple physical and chemical features to integrate cells, scaffolds, and signaling molecules for tissue regeneration. Due to their highly hydrophilic nature hydrogels can recreate nutrient-rich aqueous environments for cells. Soluble regulatory molecules can be incorporated to guide cell proliferation and differentiation. Importantly, the controlled dynamic parameters and spatial distribution of chemical cues in hydrogel scaffolds are critical for cell-cell communication, cell-scaffold interaction, and morphogenesis. Herein, we review biomimetic hydrogels that provide cells with spatiotemporally controlled chemical cues as tissue engineering scaffolds. Specifically, hydrogels with temporally controlled growth factor-release abilities, spatially controlled conjugated bioactive molecules/motifs, and targeting delivery and reload properties for tissue engineering applications are discussed in detail. Examples of hydrogels that possess clinically favorable properties, such as injectability, self-healing ability, stimulus-responsiveness, and pro-remodeling features, are also covered.

Abstract
Casein, a major protein content in the milk has been extensively used in drug delivery due to its unique structural features. Fabrication of nanofibers from casein along with nanoparticles for tissue engineering applications has been explored in this study. Nanofibers fabrication is achieved by co-electrospinning of casein with poly (ethylene oxide) in sodium dodecyl sulphate (SDS) aqueous solution. Stabilization of silver nanoparticles has been achieved by the presence of SDS in the nanofiber matrix. The influence of conductivity on the nanofiber fabrication has also been studied. The nanofibrous mats have been characterized using techniques such as scanning electron microscope (SEM) and high resolution-transmission electron microscope (HR-TEM). Antimicrobial properties of the nanofibers have been assessed and the cellular biocompatibility of the material has been evaluated using cultured fibroblast (NIH-3T3) cells. Silver nanoparticles incorporated nanofibers showed good antimicrobial property against both gram negative and gram positive bacteria. In addition, the nanofiber matrix exhibited good biocompatibility for the fibroblast cell proliferation. These results pave the way for extending the use of casein based nanofibers in the skin care applications.
