Mohamad EA, Yousuf AA, Mohamed RH, Mohammed HS. Preparation and characterization of chitosan-coated noisomal doxorubicin for enhanced its medical application. JOURNAL OF BIOMATERIALS SCIENCE. POLYMER EDITION 2024:1-16. [PMID: 38923918 DOI: 10.1080/09205063.2024.2370591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 06/14/2024] [Indexed: 06/28/2024]
Abstract
This study aimed to synthesize and characterize chitosan-coated noisomal doxorubicin for the purpose of enhancing its medical application, particularly in the field of cancer treatment. Doxorubicin, a potent chemotherapeutic agent, was encapsulated within noisomes, which are lipid-based nanocarriers known for their ability to efficiently deliver drugs to target sites. Chitosan, a biocompatible and biodegradable polysaccharide, was used to coat the surface of the noisomes to improve their stability and enhance drug release properties. The synthesized chitosan-coated noisomal doxorubicin was subjected to various characterization techniques to evaluate its physicochemical properties. Transmission electron microscopy (TEM) revealed a spherical structure with a diameter of 500-550 ± 5.45 nm and zeta potential of +11 ± 0.13 mV with no aggregation or agglomeration. Chitosan-coated noisomes can loaded doxorubicin with entrapping efficacy 75.19 ± 1.45%. While scanning electron microscopy (SEM) revealed well-defined pores within a fibrous surface. It is observed that chitosan-coated niosomes loading doxorubicin have optimum roughness (22.88 ± 0.71 nm). UV spectroscopy was employed to assess the drug encapsulation efficiency and release profile. Differential scanning calorimetry (DSC) helped determine the thermal behavior, which indicated a broad endotherm peak at 52.4 °C, while X-ray diffraction (XRD) analysis provided information about the crystallinity of the formulation with an intense peak at 23.79°. Fourier-transform infrared spectroscopy (FTIR) indicated the formation of new bonds between the drug and the polymer. The findings from this study will contribute to the knowledge of the physical and chemical properties of the synthesized formulation, which is crucial for ensuring its stability, drug release kinetics, and biological activity. The enhanced chitosan-coated noisomal doxorubicin has the potential to improve the effectiveness and safety of doxorubicin in cancer treatment, offering a promising strategy for enhanced medical applications.

Heliyon 2024; 10:e31212. [PMID: 38841488 PMCID: PMC11152904 DOI: 10.1016/j.heliyon.2024.e31212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Revised: 05/11/2024] [Accepted: 05/13/2024] [Indexed: 06/07/2024] Open
Abstract
Functionalized graphene oxide nanoparticles (NPs) have emerged as promising nanocarriers for drug delivery in lung cancer therapy. Quercetin and lurbinectedin encapsulated in graphene oxide (GO) NPs are tested for treating A549 lung cancer cells. Spectroscopic analyses show that graphene oxide functionalization creates a transparent, smooth surface for drug loading. Treatment with quercetin/lurbinectedin-loaded GO NPs induces notable cytotoxic effects in lung cancer cells, as evidenced by distinct morphological alterations and confirmed apoptotic cellular death observed through fluorescence microscopy. Additionally, our study highlights the impact of this approach on lung cancer metastasis, supported by qRT-PCR analysis of relative gene expression levels, including p53, Bax, Caspase-3, and Bcl 2, revealing robust molecular mechanisms underlying therapeutic efficacy against A549 and PC9 cell lines. Flow cytometric analyses further confirm the induction of cellular death in lung cancer cells following administration of the nanoformulation. Our findings show that quercetin/lurbinectedin-loaded GO NPs may be a promising lung cancer treatment, opening new avenues for targeted and effective therapies.

Abstract
Nanoniosome-based drug codelivery systems have become popular therapeutic instruments, demonstrating tremendous promise in cancer therapy, infection treatment, and other therapeutic domains. An emerging form of vesicular nanocarriers, niosomes are self-assembling vesicles composed of nonionic surfactants, along with cholesterol or other amphiphilic molecules. This comprehensive review focuses on how nanosystems may aid in making anticancer and antibacterial pharmaceuticals more stable and soluble. As malleable nanodelivery instruments, the composition, types, preparation procedures, and variables affecting the structure and stability of niosomes are extensively investigated. In addition, the advantages of dual niosomes for combination therapy and the administration of multiple medications simultaneously are highlighted. Along with categorizing niosomal drug delivery systems, a comprehensive analysis of various preparation techniques, including thin-layer injection, ether injection, and microfluidization, is provided. Dual niosomes for cancer treatment are discussed in detail regarding the codelivery of two medications and the codelivery of a drug with organic, plant-based bioactive compounds or gene agents. In addition, niogelosomes and metallic niosomal carriers for targeted distribution are discussed. The review also investigates the simultaneous delivery of bioactive substances and gene agents, including siRNA, microRNA, shRNA, lncRNA, and DNA. Additional sections discuss the use of dual niosomes for cutaneous drug delivery and treating leishmanial infections, Pseudomonas aeruginosa, and Mycobacterium tuberculosis. The study concludes by delineating the challenges and potential routes for nanoniosome-based pharmaceutical codelivery systems, which will be useful for nanomedicine practitioners and researchers.

Current advances in niosomes applications for drug delivery and cancer treatment. Mater Today Bio 2023; 23:100837.

Abstract
The advent of nanotechnology has led to an increased interest in nanocarriers as a drug delivery system that is efficient and safe. There have been many studies addressing nano-scale vesicular systems such as liposomes and niosome is a newer generation of vesicular nanocarriers. The niosomes provide a multilamellar carrier for lipophilic and hydrophilic bioactive substances in the self-assembled vesicle, which are composed of non-ionic surfactants in conjunction with cholesterol or other amphiphilic molecules. These non-ionic surfactant vesicles, simply known as niosomes, can be utilized in a wide variety of technological applications. As an alternative to liposomes, niosomes are considered more chemically and physically stable. The methods for preparing niosomes are more economic. Many reports have discussed niosomes in terms of their physicochemical properties and applications as drug delivery systems. As drug carriers, nano-sized niosomes expand the horizons of pharmacokinetics, decreasing toxicity, enhancing drug solvability and bioavailability. In this review, we review the components and fabrication methods of niosomes, as well as their functionalization, characterization, administration routes, and applications in cancer gene delivery, and natural product delivery. We also discuss the limitations and challenges in the development of niosomes, and provide the future perspective of niosomes.

Abstract
Nanoformulations have become increasingly useful as drug delivery technologies in recent decades. As therapeutics, oral administration is the most common delivery method, although it is not always the most effective route because of challenges with swallowing, gastrointestinal discomfort, low solubility, and poor absorption. One of the most significant barriers that medications must overcome to exert a therapeutic effect is the impact of the first hepatic transit. Studies have shown that controlled-release systems using nanoparticles composed of biodegradable natural polymers significantly improve oral administration, which is why these materials have attracted significant attention. Chitosan possesses a wide variety of properties and functions in the pharmaceutical as well as healthcare industries. Drug encapsulation and transport within the body are two of its most important features. Moreover, chitosan can enhance drug efficacy by facilitating drug interaction with target cells. Based on its physicochemical properties, chitosan can potentially be synthesized into nanoparticles, and this review summarizes recent advances and applications of orally delivered chitosan nanoparticle interventions.

Abstract
Over the past decade, smart and functional biomaterials have escalated as one of the most rapidly emerging fields in the life sciences because the performance of biomaterials could be improved by careful consideration of their interaction and response with the living systems. Thus, chitosan could play a crucial role in this frontier field because it possesses many beneficial properties, especially in the biomedical field such as excellent biodegradability, hemostatic properties, antibacterial activity, antioxidant properties, biocompatibility, and low toxicity. Furthermore, chitosan is a smart and versatile biopolymer due to its polycationic nature with reactive functional groups that allow the polymer to form many interesting structures or to be modified in various ways to suit the targeted applications. In this review, we provide an up-to-date development of the versatile structures of chitosan-based smart biomaterials such as nanoparticles, hydrogels, nanofibers, and films, as well as their application in the biomedical field. This review also highlights several strategies to enhance biomaterial performance for fast growing fields in biomedical applications such as drug delivery systems, bone scaffolds, wound healing, and dentistry.

Abstract
As one of the newest generations of nanoplatforms, smart nanotheranostics have attracted signifivant attentions for medical applications, especially in oncology and cancer treatment. Indeed, their capability to provide treatment and diagnosis simultaneously leads to reduce time and side effects along with improving the performance. This study aims to introduce a novel smart nano-platform composed of doxorubicin-loaded pH-responsive stealth niosomes containing CdSe/ZnS Quantum dots as an imaging agent. Drug loaded nano-platform was fabricated via thin-film hydration method and then evaluated using different physicochemical tests. The entrapment efficiency and release profile of doxorubicin were assessed at three different pH (4, 6.5, and 7.4). Biological features and imaging ability of the nanoparticles were also evaluated by MTT assay, apoptosis assay, and fluorescence microscopy. Results showed that the fabricated nanoparticles were round-shaped, with a mean size of about 100±10 nm, -2 mV surface charge, and about 87% entrapment efficiency. The drug release profile presented a pH-responsive behavior (80, 60, and 40% drug release in pH 4, 6.5, and 7.4, respectively). The bio-activity assessments showed nearly 55% cytotoxicity effects via inducing cell apoptosis. Besides, the uptake of samples by the cells was confirmed through fluorescence imaging. Based on the results, this new nanoformulation could be considered as a candidate for future cancer theranostic applications.

Abstract
In this work, we synthesized chitosan 5 kDa conjugates with β-cyclodextrins with various substituents as promising mucoadhesive carriers for the delivery of fluoroquinolones using the example of levofloxacin. The obtained conjugates were comprehensively characterized by spectral methods (UV-Vis, ATR-FTIR, 1H NMR, SEM). The physico-chemical properties of the complex formations were studied by IR, UV, and fluorescence spectroscopy. The dissociation constants of complexes with levofloxacin were determined. Complexation with conjugates provided four times slower drug release in comparison with plain CD and more than 20 times in comparison with the free drug. The antibacterial activity of the complexes was tested on model microorganisms Gram-negative bacteria Escherichia coli ATCC 25922 and Gram-positive Bacillus subtilis ATCC 6633. The complex with the conjugate demonstrated the same initial levofloxacin antibacterial activity but provided significant benefits, e.g., prolonged release.
