Abstract
Buccal drug administration may be chosen as a medication route to treat various diseases for local or systemic effects. This study proposes the development of a thermosensitive hydrogel containing curcumin-loaded lipid-core nanocapsules coated with chitosan to increase mucoadhesion, circumventing several limitations of this route of administration. Hydroxypropylmethylcellulose and Poloxamer® 407 were incorporated for hydrogel production. Physicochemical characterization parameters, such as particle size distribution, mean diameter, polydispersity index, zeta potential, and morphology, were analyzed. Spherical homogeneous particles were obtained with average diameter, of 173 ± 22 nm for LNCc (curcumin lipid-core nanocapsules) and 179 ± 48 nm for CLNCc (chitosan-curcumin lipid-core nanocapsules). A PDI equal to 0.09 ± 0.02 for LNCc and 0.26 ± 0.01 for CLNCc confirmed homogeneity. Tensile analysis and washability test on porcine buccal mucosa indicated higher mucoadhesion for hydrogels in comparison to the nanocapsules in suspension, remaining on the mucous membrane up to 8 h (10.92 ± 3.95 µg of curcumin washed for H-LNCc and 28.41 ± 24.47 µg for H-CLNCc) versus the latter, which remained washed on the membrane for 90 min only (62.60 ± 4.72 µg for LNCc and 52.08 ± 1.63 µg for CLNCc). The irritant potential (IR) of the formulations was evaluated by the hen's egg chorioallantoic membrane test (HET-CAM), with no irritation phenomena observed. Formulations were tested for their efficacy in an in vitro model against oral squamous cancer cell line, showing a significant reduction in cell viability on all tested groups. These findings demonstrated that the proposed nanosystem is mucoadhesive and has potential to deliver buccal treatments.

Conjugates of Chitosan with β-Cyclodextrins as Promising Carriers for the Delivery of Levofloxacin: Spectral and Microbiological Studies. Life (Basel) 2023; 13:life13020272. [PMID: 36836630 PMCID: PMC9960298 DOI: 10.3390/life13020272] [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: 12/31/2022] [Revised: 01/14/2023] [Accepted: 01/17/2023] [Indexed: 01/20/2023] Open
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.

Abstract
Several antithrombotic drugs are available to treat cardiovascular diseases due to its high mortality and morbidity worldwide. Despite these, severe adverse effects that can lead to treatment withdrawal have been described, highlighting the importance of new therapies. Thus, this work describes the development of fucoidan microparticles containing acetylsalicylic acid (MP/F4M) for pulmonary delivery and in vitro, ex vivo, and in vivo evaluation. Microparticles were prepared via spray-drying and characterized in vitro (mucoadhesive properties, coagulation time, platelet aggregation, adhesion, and hemolysis) followed by ex vivo platelet aggregation, in vivo arterial thrombosis, and hemorrhagic profile. The formulation physicochemical characterization showed suitable characteristics along with delayed drug release, increased breathable particle fraction, and high washability resistance as well as antiplatelet activity and enhanced platelet adhesion in vitro. In in vivo assays, MP/F4M protected against arterial thrombosis, without changes in the hemorrhagic profile. Finally, no lung changes were observed after prolonged pulmonary administration, whereas isolated ASA led to an inflammatory response. In conclusion, pulmonary administration of fucoidan microparticles with an antiplatelet drug may be an alternative therapy to treat cardiovascular diseases, opening the field for different formulations.

Carbohydr Polym 2022; 277:118784. [PMID: 34893219 DOI: 10.1016/j.carbpol.2021.118784] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 09/28/2021] [Accepted: 10/14/2021] [Indexed: 12/31/2022]
Abstract
Polysaccharides can be elite carriers for therapeutic molecules due to their versatility and low probability to trigger toxicity and immunogenic responses. Local and systemic therapies can be achieved through particle pulmonary delivery, a promising non-invasive alternative. Successful pulmonary delivery requires particles with appropriate flowability to reach alveoli and avoid premature clearance mechanisms. Polysaccharides can form micro-, nano-in-micro-, and large porous particles, aerogels, and hydrogels. Herein, the characteristics of polysaccharides used in drug formulations for pulmonary delivery are reviewed, providing insights into structure-function relationships. Charged polysaccharides can confer mucoadhesion, whereas the ability for specific sugar recognition may confer targeting capacity for alveolar macrophages. The method of particle preparation must be chosen considering the properties of the components and the delivery device to be utilized. The fate of polysaccharide-based carriers is dependent on enzyme-triggered hydrolytic and/or oxidative mechanisms, allowing their complete degradation and elimination through urine or reutilization of released monosaccharides.

Novel Drug Carrier: 5-Fluorouracil Formulation in Nanoporous Biogenic Mg-calcite from Blue Crab Shells-Proof of Concept. ACS OMEGA 2021; 6:27781-27790. [PMID: 34722978 PMCID: PMC8552355 DOI: 10.1021/acsomega.1c03285] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Accepted: 09/09/2021] [Indexed: 06/13/2023]
Abstract
The ever-growing demand for novel, cheaper, and more effective drugs has put nanomedicine and targeted drug delivery to the forefront of scientific innovation. Owing to its porous three-dimensional (3D)-nanostructure and properties, the biogenic calcite from wasted blue crab shells is employed in the present work as a new drug carrier for 5-fluorouracil (5-FU), a drug widely used in cancer therapy. The drug solution has been loaded in the porous nanoarchitecture of the powdered biogenic material and further pelleted in tablets with a 5-FU concentration of 1.748 mg/g. Their structural and morphological properties were characterized using Raman, X-ray diffraction, and scanning electron microscopy. Confocal micro-Raman spectra of tablet surface showed a typical signal of biogenic carbonate with preserved carotenoids and carotenoproteins found in the native waste shell, while the drug Raman signal was absent, indicating its adsorption in the intricate nanoporous biogenic carrier. The slow release of the drug from the newly formulated tablet was investigated by tracking the surface-enhanced Raman scattering (SERS) signal of the tablet solution in a series of time-dependent experiments. The SERS signal quantification is achieved using the well-known SERS spectral fingerprint of 5-fluorouracil aqueous solution adsorbed on Ag nanoparticles. The proof of concept is demonstrated by quantifying the slow release of the drug through the characteristic SERS band intensity of 5-FU in a time course of 26 h. This proof of concept boosted further investigations concerning the released drug identity in simulated solutions that mimic the pH of the upper- and lower gastrointestinal tract, as well as the multiple possibilities to control porosity and composition during powdering and treatment of biogenic material, to achieve the most convenient formulation for relevant biomedical drug delivery. Nonetheless, the present results showed great promise for innovative reusing waste biogenic 3D-nanomaterials of aquatic origin as advantageous drug carriers for slow release purposes, in line with the concept of blue bioeconomy.

Ferri-Liposomes: Preformulation and Selective Cytotoxicity against A549 Lung Cancer Cells. Pharmaceutics 2021; 13:pharmaceutics13050712.

Abstract
Liposomes have become successful nanostructured systems used in clinical practices. These vesicles are able to carry important drug loadings with noteworthy stability. The aim of this work was to develop iron oxide-loaded stealth liposomes as a prospective alternative for the treatment of lung cancer. In this study, citric acid iron oxide nanoparticles (IONPs-Ac) were synthesized and encapsulated in stealth liposomes. Their cytotoxicity and selectivity against lung tumor cells were assessed. Stealth liposomal vesicles, with relevant content of IONPs-Ac, named ferri-liposomes (SL-IONPs-Ac), were produced with an average size of 200 nm. They displayed important cytotoxicity in a human lung cancer cells model (A549 cells), even at low concentrations, whereas free IONPs-Ac displayed adequate biocompatibility. Nevertheless, the treatment at the same concentration of ferri-liposomes against HEK-293 cells, a normal human cell lineage, was not significantly cytotoxic, revealing a probable lung tumor selectiveness of the fabricated formulation. Furthermore, from the flow cytometry studies, it was possible to infer that ferri-liposomes were able to induce A549 tumor cells death through apoptosis/ferroptosis processes, evidenced by a significant reduction of the mitochondrial membrane potential.

Abstract
Resin infiltrants have been effectively applied in dentistry to manage non-cavitated carious lesions in proximal dental surfaces. However, the common formulations are composed of inert methacrylate monomers. In this study, we developed a novel resin infiltrant with microcapsules loaded with an ionic liquid (MC-IL), and analyzed the physical properties and cytotoxicity of the dental resin. First, the ionic liquid 1-n-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (BMI.NTf2) was synthesized. BMI.NTf2 has previously shown antibacterial activity in a dental resin. Then, MC-IL were synthesized by the deposition of a preformed polymer. The MC-IL were analyzed for particle size and de-agglomeration effect via laser diffraction analysis and shape via scanning electron microscopy (SEM). The infiltrants were formulated, and the MC-IL were incorporated at 2.5%, 5%, and 10 wt%. A group without MC-IL was used as a control. The infiltrants were evaluated for ultimate tensile strength (UTS), contact angle, surface free energy (SFE), and cytotoxicity. The MC-IL showed a mean particle size of 1.64 (±0.08) μm, shriveled aspect, and a de-agglomeration profile suggestive of nanoparticles' presence in the synthesized powder. There were no differences in UTS among groups (p > 0.05). The incorporation of 10 wt% of MC-IL increased the contact angle (p < 0.05), while the addition from 5 wt% reduced the SFE in comparison to the control group (p < 0.05). The human cell viability was above 90% for all groups (p > 0.05). The incorporation of microcapsules as a drug-delivery system for ionic liquids may be a promising strategy to improve dental restorative materials. Ionic liquid was used as core of synthesized polymeric-based microcapsules. Microcapsules doped with ionic liquid were incorporated into a dental resin. The dental resins presented proper mechanical and biocompatibility properties. The particles incorporation reduced the surface free energy of dental resins. Biointeractivity may be obtained through MC-IL addition into dental resins.

Abstract
Dermatological applications of phloretin are restricted by its poor aqueous solubility. Nanotechnology has been proposed as strategy to increase the apparent drug solubility in aqueous media. This study aimed to develop, characterize, and evaluate the antitumoral effects and safety of polymeric nanocapsules containing phloretin (NCPhl). Further, to incorporate NC-Phl in an innovative semi-solid formulation (HG-NCPhl) to evaluate its performance using porcine skin model. NC-Phl was prepared and the effects in MRC5, HACAT, and SK-mel28 cells were evaluated. Hydrogels were prepared with Lecigel ® and characterized for their nanotechnological properties, adhesion (in vitro washability), and penetration/permeation studies in porcine skin. NC-Phl had a cytotoxic effect against Sk-Mel-28 cells and the population doubling time was increased upon treatment with NC-Phl for longer culture periods; notably when cells were treated for 72 h and then followed for 7 days after the treatment was removed (p < 0.05). HG-NC-Phl was considered adhesive and had a higher capacity to penetrate all skin layers compared with HG-Phl (p < 0.05). The innovative hydrogel HGNC-Phl promoted a drug-reservoir in the stratum corneum and higher penetration of the flavonoid into the epidermis. Therefore, this approach can be considered as a platform to establish versatile dermatological solutions for both cosmeceutics and melanoma therapy.

Abstract
5-Fluorouracil (5-FU) is a standard treatment option for colorectal cancer (CRC) but its rapid metabolism and systemic instability (short half-life) has hindered its therapeutic efficacy. The objective of this study was to develop a novel drug delivery system, solid lipid nanoparticle (SLN), capable of delivering high payload of 5-FU to treat CRC. The rational was to improve 5FU-nanocarrier compatibility and therapeutic efficacy. The SLN-loaded 5-FU was developed by utilizing a Strategic and unique Method to Advance and Refine the Treatment (SMART) of CRC through hot and cold homogenization approach. The SLN was made of unique PEGylated lipids and combination of the surfactants. Cytotoxicity studies, clonogenic assay, flow cytometry and confocal imaging were conducted to evaluate the effectiveness and cellular uptake of 5FU-SLN4 in HCT-116 cancer cells. Pharmacokinetic (PK) parameters and receptor expressions were determined while tumor efficacy studies were conducted on mouse bearing subcutaneous HCT-116 cancer. Among the all the formulations, 5FU-SLN4 was the most effective with particle size of was 263 ± 3 nm, zeta potential was 0.1 ± 0.02 and entrapment efficiency of 81 ± 10%. The IC50 value of 5FU-SLN4 (7.4 ± 0.02 µM) was 2.3 fold low compared with 5-FU (17.7 ± 0.03 µM). For tumor efficacy studies, 5FU-SLN4 significantly inhibited tumor growth in comparison to 5-FU while area-under plasma concentration-time curve (AUC) of 5FU-SLN4 was 3.6 fold high compared with 5-FU. HER2 receptors expression were markedly reduced in 5-FU-SLN4 treated mice compared with 5FU and liver and kidney tissues showed no toxicity at dose of 20 mg/kg. 5FU-SLN4 was highly cytotoxic against HCT-116 cells and significantly inhibited subcutaneous tumor growth in mice compared with 5-FU. This emphasizes the significance of developing a smart nano-delivery system to optimize the delivery efficiency of anticancer drugs to tumors.

[PMID: 31642783 DOI: 10.2174/1568026619666191023130524] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Revised: 09/29/2019] [Accepted: 09/30/2019] [Indexed: 12/16/2022]
Abstract
Melanoma is a malignant skin tumor that results in poor disease prognosis due to unsuccessful
treatment options. During the early stages of tumor progression, surgery is the primary approach
that assures a good outcome. However, in the presence of metastasis, melanoma hasbecome almost
immedicable, since the tumors can not be removed and the disease recurs easily in a short period of
time. However, in recent years, the combination of nanomedicine and chemotherapeutic drugs has offered
promising solutions to the treatment of late-stage melanoma. Extensive studies have demonstrated
that nanomaterials and their advanced applications can improve the efficacy of traditional chemotherapeutic
drugs in order to overcome the disadvantages, such as drug resistance, low drug delivery rate and
reduced targeting to the tumor tissue. In the present review, we summarized the latest progress in imaging
diagnosis and treatment of melanoma using functional nanomaterials, including polymers,
liposomes, metal nanoparticles, magnetic nanoparticles and carbon-based nanoparticles. These
nanoparticles are reported widely in melanoma chemotherapy, gene therapy, immunotherapy, photodynamic
therapy, and hyperthermia.

Abstract
At present, there is no accurate and effective method for treating neoplastic pericardial effusion. This study analyzed the current literature on the treatment of neoplastic pericardial effusion to provide advice and guidance for clinical treatment. Surgical treatments include pericardial puncture, extension of catheter drainage, pericardial window, and surgical pericardiotomy. Each surgical procedure has a corresponding indication, and the best treatment is selected according to the patient's specific conditions. Systemic chemotherapy is effective in lymphoma and small cell lung cancer that are sensitive to chemotherapeutic drugs. Although pericardial injection of drugs is effective for pericardial tamponade and recurrent pericardial effusion, these methods can only temporarily relieve symptoms and cannot prolong the life of patients. In recent years, immunotherapy, especially adoptive immunotherapy, has achieved good results in the treatment of neoplastic pericardial effusion, thus providing a novel treatment option for neoplastic pericardial effusion.

Abstract
Background Human melanoma is a malignant tumor originated from melanocytes with high invasion, metastasis, and poor prognosis. In this study, the effects of naphthalimides UNBS5162 and amonafide on the properties of proliferation and apoptosis in human melanoma cells were confirmed. Methods Cell proliferation was determined by CCK8 and clone formation assay. Transwell assay was performed to detect the migration and invasion of M14 and A375 cells. Cell apoptosis was estimated using flow cytometry. Results In a drug sensitivity assay, cell viability decreased with increasing concentrations of UNBS5162 or amonafide. Likewise, proliferation of M14 or A375 cells treated with 10 μM UNBS5162 or 8 μM amonafide decreased significantly when compared with negative control (NC) cells, their inhibition effect verified by means of a clone formation assay. After the treatment with UNBS5162 or amonafide, the migration of melanoma cells was inhibited in a dosede-pendent manner. The number of invaded cells treated with UNBS5162 was also significantly reduced when compared with those of the NC cells. The apoptotic cell numbers treated with UNBS5162 or amonafide decreased significantly when compared with the M14 and A375 cells in the NC group. According to Western blot results, phosphorylation of AKT and expressions of mesenchymal marker factors were inhibited in cells treated with UNBS5162 or amonafide. Conclusion These results reveal that UNBS5162 inhibits the cell activity of melanoma cells through the AKT/mTOR signaling pathway, and reverses epithelial–mesenchymal transition conversion in human melanoma cells. This study on UNBS5162 and amonafide in melanomas provides an experimental basis of their uses and potential value on human melanoma treatment.

Targeted Therapy against Metastatic Melanoma Based on Self-Assembled Metal-Phenolic Nanocomplexes Comprised of Green Tea Catechin. ADVANCED SCIENCE (WEINHEIM, BADEN-WURTTEMBERG, GERMANY) 2019; 6:1801688. [PMID: 30886799 PMCID: PMC6402403 DOI: 10.1002/advs.201801688] [Citation(s) in RCA: 76] [Impact Index Per Article: 15.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/27/2018] [Revised: 12/09/2018] [Indexed: 02/05/2023]
Abstract
The targeted therapy of metastatic melanoma is an important yet challenging goal that has received only limited attention to date. Herein, green tea polyphenols, (-)-epigallocatechin-3-gallate (EGCG), and lanthanide metal ions (Sm3+) are used as building blocks to engineer self-assembled SmIII-EGCG nanocomplexes with synergistically enhanced tumor inhibitory properties. These nanocomplexes have negligible systemic toxic effects on healthy cells but cause a significant reduction in the viability of melanoma cells by efficiently regulating their metabolic pathways. Moreover, the wound-induced migration of melanoma cells can be efficiently inhibited by SmIII-EGCG, which is a key criterion for metastatic melanoma therapy. In a mouse melanoma tumor model, SmIII-EGCG is directly compared with a clinical anticancer drug, 5-fluorouracil and shows remarkable tumor inhibition. Moreover, the targeted therapy of SmIII-EGCG is shown to prevent metastatic lung melanoma from spreading to main organs with no adverse side effects on the body weight or organs. These in vivo results demonstrate significant advantages of SmIII-EGCG over its clinical counterpart. The results suggest that these green tea-based, self-assembled nanocomplexes possess all of the key traits of a clinically promising candidate to address the challenges associated with the treatment of advanced stage metastatic melanoma.

Buccal Bullfrog ( Rana catesbeiana Shaw) Oil Emulsion: A Mucoadhesive System Intended for Treatment of Oral Candidiasis. Pharmaceutics 2018; 10:E257. [PMID: 30513861 PMCID: PMC6320908 DOI: 10.3390/pharmaceutics10040257] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2018] [Revised: 11/05/2018] [Accepted: 11/07/2018] [Indexed: 11/17/2022] Open
Abstract
Oral candidiasis (OC) is an infectious disease caused by microorganisms of the genus Candida, leading to lesions in the buccal cavity. Its treatment consists of the administration of topical or systemic antifungal agents, which may compromise the patient compliance due to its side effects, highlighting the need for alternative treatments. In this scenario, bullfrog oil, an animal oil composed of a pool of saturated and unsaturated fatty acids, is introduced as a potential antifungal raw material. Thus, the aim of this work was to produce a mucoadhesive emulsified system able to deliver the bullfrog oil in the buccal cavity to treat the OC. The emulsion was produced and characterized by visual inspection, droplet size, polydispersity index (PdI), and zeta potential over the course of 60 days. In addition, its mucoadhesive ability was evaluated using an in vitro mucin model. The antifungal activity, evaluated by the broth microdilution assay and the biocompatibility, performed against human erythrocytes, were also carried out. The emulsion showed a droplet size of 320.79 ± 35.60 nm, a PdI of 0.49 ± 0.08, and a zeta potential of -38.53 ± 6.23 mV, with no significant changes over 60 days. The mucoadhesive properties of the system was improved by the use of pharmaceutical excipients. The antifungal activity showed that the bullfrog oil and the emulsion were able to inhibit the growth of different Candida species. Furthermore, the emulsion showed no significant hemolytic effect. Overall, the system showed suitable physicochemical characteristics and biocompatibility, with substantial in vitro antifungal activity, suggesting that this system can be further investigated for OC treatment.
