RSC Adv 2024; 14:11124-11140. [PMID: 38606056 PMCID: PMC11008427 DOI: 10.1039/d4ra01334d] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Accepted: 04/01/2024] [Indexed: 04/13/2024] Open
Abstract
Differences in pH between the tumour interstitium and healthy tissues can be used to induce conformational changes in the nanocarrier structure, thereby triggering drug release at the desired site. In the present study, novel pH-responsive nanocarriers were developed by modifying conventional niosomes with hexadecyl-poly(acrylic acid)n copolymers (HD-PAAn). Niosomal vesicles were prepared by the thin film hydration method using Span 60, Span 60/Tween 60 and cholesterol as main constituents, and HD-PAA modifiers of different concentrations (0.5, 1, 2.5, 5 mol%). Next, two model substances, a water-soluble fluorescent dye (calcein) and a hydrophobic agent with pronounced antineoplastic activity (curcumin), were loaded in the aqueous core and hydrophobic membrane of the elaborated niosomes, respectively. Physicochemical properties of blank and loaded nanocarriers such as hydrodynamic diameter (Dh), size distribution, zeta potential, morphology and pH-responsiveness were investigated in detail. The cytotoxicity of niosomal curcumin was evaluated against human malignant cell lines of different origins (MJ, T-24, HUT-78), and the mechanistic aspects of proapoptotic effects were elucidated. The formulation composed of Span 60/Tween 60/cholesterol/2.5% HD-PAA17 exhibited optimal physicochemical characteristics (Dh 302 nm; ζ potential -22.1 mV; high curcumin entrapment 83%), pH-dependent drug release and improved cytotoxic and apoptogenic activity compared to free curcumin.

Alotaibi SH. Tretinoin (2,4-difluoro-phenyl) triazole activates proapoptotic protein expression and targets NRP2 protein to inhibit esophageal carcinoma cell growth. ENVIRONMENTAL TOXICOLOGY 2024; 39:942-951. [PMID: 37972228 DOI: 10.1002/tox.24030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/22/2023] [Revised: 10/13/2023] [Accepted: 10/31/2023] [Indexed: 11/19/2023]
Abstract
The present study investigated the effect of tretinoin (2,4-difluoro-phenyl) triazole (TDFPT) on the growth and proliferation of Kyse-270 and EC9706 esophageal carcinoma cells and explored the underlying mechanism. The results demonstrated that TDFPT treatment of Kyse-270 and EC9706 cells led to a dose-dependent reduction in cell proliferation. Colony formation was significantly (p < .05) reduced in Kyse-270 and EC9706 cells on treatment with various concentrations of TDFPT. In TDFPT-treated Kyse-270 and EC9706 cells, the expression of Bcl-2 protein showed a remarkable decrease, whereas the level of Bax protein was found to be higher compared with the control cells. Cell invasion showed a prominent decrease in Kyse-270 and EC9706 cells on treatment with TDFPT. Treatment with TDFPT led to a prominent suppression in the expression of MMP-9 and NRP2 in Kyse-270 and EC9706 cells. In silico studies using the AutoDock Vina and discovery studio software revealed that various confirmations of TDFPT bind to NRP2 protein with the affinity ranging from -8.6 to -6.1 kcal/mol. It was found that the TDFPT interacts with NRP2 protein by binding to alanine (ALA A:295), proline (PRO A:306), glutamine (GLN A:307), and isoleucine (ILE A:293) amino acid residues. In summary, TDFPT exposure suppresses esophageal carcinoma cell proliferation, inhibits colony formation ability, and activates apoptotic pathway. Thus, TDFPT acts as an effective antiproliferative agent for esophageal carcinoma cells and needs to be investigated further as chemotherapeutic molecule.

Abstract
The treatment of wounds is a serious problem all over the world and imposes a huge financial burden on each and every nation. For a long time, researchers have explored wound dressing that speeds up wound healing. Traditional wound dressing does not respond effectively to the wound-healing process as expected. Therapeutic active derived from plant extracts and extracted bioactive components have been employed in various regions of the globe since ancient times for the purpose of illness, prevention, and therapy. About 200 years ago, most medical treatments were based on herbal remedies. Especially in the West, the usage of herbal treatments began to wane in the 1960s as a result of the rise of allopathic medicine. In recent years, however, there has been a resurgence of interest in and demand for herbal medicines for a number of reasons, including claims about their efficacy, shifting consumer preferences toward natural medicines, high costs and negative side effects of modern medicines, and advancements in herbal medicines brought about by scientific research and technological innovation. The exploration of medicinal plants and their typical uses could potentially result in advanced pharmaceuticals that exhibit reduced adverse effects. This review aims to present an overview of the utilization of nanocarriers in plant-based therapeutics, including its current status, recent advancements, challenges, and future prospects. The objective is to equip researchers with a comprehensive understanding of the historical background, current state, and potential future developments in this emerging field. In light of this, the advantages of nanocarriers based delivery of natural wound healing treatments have been discussed, with a focus on nanofibers, nanoparticles, nano-emulsion, and nanogels.

Int J Pharm 2023; 631:122508. [PMID: 36539166 DOI: 10.1016/j.ijpharm.2022.122508] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 12/09/2022] [Accepted: 12/14/2022] [Indexed: 12/23/2022]
Abstract
Asiaticoside (AST) is a naturally available phytoconstituent that enables effective wound healing mainly by promoting collagen biosynthesis. However, the physicochemical nature of AST such as high molecular weight (959.12 g/mol), poor water solubility and poor permeability limits its therapeutic effects. This study aims to develop Asiaticoside polymeric nanoparticles (AST PNP) embedded in a gelatin based biodegradable hydrogel (15 % w/v) for application in the wound cavity to enable sustained release of AST and enhance its therapeutic effects. The AST PNP were fabricated in the desired size range (168.4 nm; PDI (0.09)) and the morphology, rate of fluid uptake, rate of water loss, and water vapor transmission rate of AST PNP incorporated hydrogel were determined. AST PNP gel showed porous structural morphology and possessed ideal characteristics as a graft for wound healing. The drug release kinetics and cellular uptake of AST PNP were investigated wherein, AST PNP demonstrated sustained release profile upto 24 h in comparison to free AST (complete release within 6 h) and exhibited an enhanced intra-cellular uptake in fibroblasts within 3 h compared to the free drug. In-vitrocell culture studies also demonstrated significant proliferation and migration of fibroblasts in the presence of AST PNP. Additionally, AST PNP gel upon application to the wounds of diabetic rats depicted improved wound healing efficacy in terms of improved collagen biosynthesis, upregulated COL-1 protein level (∼1.85 fold vs free AST), and enhanced expression of α-SMA compared to control groups. Altogether, formulation of AST as polymeric nanoparticles in a gel based carrier offered significant improvement in the therapeutic properties of AST for the management of diabetic wounds.

Abstract
OBJECTIVE In this work, a propranolol hydrochloride (PRH) transfersomes loaded cutaneous hydrogel patch was developed for topical drug delivery in the affected area of infantile haemangioma. METHODS Sodium cholate was used as the edge activator to prepare the transfersomes. Based on the central composite design, transfersomes hydrogel patch formulation was optimised with 48 h cumulative penetration and time lag as response values. Particle sizes and morphology of the prepared transfersomes were assessed. They were loaded in a cutaneous hydrogel patch, after which their skin permeation abilities were evaluated, and histopathological effects were investigated using guinea pigs. Moreover, in vivo pharmacokinetics studies were performed in rats. RESULTS The transfersomes system had a encapsulation efficiency of 81.84 ± 0.53%, particle size of 186.8 ± 3.38 nm, polydispersity index of 0.186 ± 0.002, and a zeta potential of -28.6 ± 2.39 mV. Transmission electron microscopy images revealed sphericity of the particles. The ex vivo drug's penetration of the optimised transfersomes hydrogel patch was 111.05 ± 11.97 μg/cm2 through rat skin within 48 h. Assessment of skin tissue did not reveal any histopathological alterations in epidermal and dermal cells. Pharmacokinetic studies showed that skin Cmax (68.22 μg/cm2) and AUC0-24 (1007.33 μg/cm2 × h) for PRH transfersomes hydrogel patch were significantly higher than those of commercially available oral dosage form and hydrogel patch without transfersomes. These findings imply that the transfersomes hydrogel patch can prolong drug accumulation in the affected skin area, and reduce systemic drug distribution via the blood stream. CONCLUSIONS The hydrogel patch-loaded PRH transfersomes is a potentially useful drug formulation for infantile haemangioma.

Abstract
Liposomes are now considered the most commonly used nanocarriers for various potentially active hydrophobic and hydrophilic molecules due to their high biocompatibility, biodegradability, and low immunogenicity. Liposomes also proved to enhance drug solubility and controlled distribution, as well as their capacity for surface modifications for targeted, prolonged, and sustained release. Based on the composition, liposomes can be considered to have evolved from conventional, long-circulating, targeted, and immune-liposomes to stimuli-responsive and actively targeted liposomes. Many liposomal-based drug delivery systems are currently clinically approved to treat several diseases, such as cancer, fungal and viral infections; more liposomes have reached advanced phases in clinical trials. This review describes liposomes structure, composition, preparation methods, and clinical applications.

Abstract
The need to develop wound healing preparations is a pressing challenge given the limitations of the current treatment and the rising prevalence of impaired healing wounds. Although herbal extracts have been used for many years to treat skin disorders, due to their wound healing, anti-inflammatory, antimicrobial, and antioxidant effects, their efficacy can be questionable because of their poor bioavailability and stability issues. Nanotechnology offers an opportunity to revolutionize wound healing therapies by including herbal compounds in nanosystems. Particularly, vesicular nanosystems exhibit beneficial properties, such as biocompatibility, targeted and sustained delivery capacity, and increased phytocompounds’ bioavailability and protection, conferring them a great potential for future applications in wound care. This review summarizes the beneficial effects of phytocompounds in wound healing and emphasizes the advantages of their entrapment in vesicular nanosystems. Different types of lipid nanocarriers are presented (liposomes, niosomes, transferosomes, ethosomes, cubosomes, and their derivates’ systems), highlighting their applications as carriers for phytocompounds in wound care, with the presentation of the state-of-art in this field. The methods of preparation, characterization, and evaluation are also described, underlining the properties that ensure good in vitro and in vivo performance. Finally, future directions of topical systems in which vesicle-bearing herbal extracts or phytocompounds can be incorporated are pointed out, as their development is emerging as a promising strategy.

Correlation between in vivo microdialysis pharmacokinetics and ex vivo permeation for sinomenine hydrochloride transfersomes with enhanced skin absorption. Int J Pharm 2022; 621:121789.

Abstract
Transdermal drug delivery systems have drawn increasing attention in recent decades. Estimation of the correlation between ex vivo permeation and in vivo absorption (EVIVC) is an indispensable issue in the research and development of transdermal pharmaceutical products. In this paper, sinomenine hydrochloride (SH) transfersomes (SHTs) were prepared with sodium deoxycholate as edge activator, while SH liposomes (SHLs) were prepared as a control preparation. The transdermal permeation characteristics differences between them were explored by an ex vivo skin permeation experiment with Franz diffusion cell and an in vivo skin/blood pharmacokinetic experiment facilitated by double-sited microdialysis sampling technique. The curves of percentage absorbed versus time (absorption curves) under the skin and in the blood were plotted according to the percentages calculated by the deconvolution approach with the application of Wagner-Nelson model, and were correlated with the ex vivo permeation curves to evaluate a level A correlation, while a level C correlation evaluation was conducted based on the in vivo steady-state blood concentration (Css) and the ex vivo steady-state transdermal permeation rate. The ex vivo permeation test indicated that the cumulative transdermal permeated amount of SH at 36 h in SHTs was about 1.7 times of that in SHLs. The skin pharmacokinetic data showed that the Css and AUC0-t of SHTs were about 8.8 and 8.0 times of those of SHLs, respectively, and the MRT0-t of SHTs was shorter. The blood pharmacokinetic data showed that the Css and AUC0-t of SHTs were about 3.7 and 2.9 times of those of SHLs, respectively. The in vivo absorption curves were correlated well with the ex vivo permeation curves. The squares of correlation coefficient (R2) for SHTs and SHLs were 0.9153 and 0.9355 respectively in the skin, were 0.8536 and 0.7747 respectively in the blood. As to level C EVIVC, there was no significant difference between the predicted Css from ex vivo and the measured Cssin vivo. The transfersomes can be employed as effective vehicles to promote the transdermal absorption of SH, and it is feasible to predict the in vivo skin/blood pharmacokinetic properties of SHLs and SHTs based on the ex vivo skin permeation characteristics.

Abstract
The extract of Teucrium marum L. (Lamiaceae) was obtained using the aerial parts of the plant, by means of a maceration process. Verbascoside, caffeic acids derivatives and flavonols were the main components contained in the extract as detected using high-performance liquid chromatography coupled with diode array detector (HPLC–DAD) as an analytical method. The extract was successfully incorporated into hyalurosomes, which were further enriched by adding a water cosolvent (glycerol) and a surfactant (Tween 80), thus obtaining glycerohyalurosomes. Liposomes, transfersomes and glycerosomes were prepared as well and used as comparisons. All vesicles were small, as the mean diameter was never higher than ~115 nm, thus ideal for topical application and stable on storage, probably thanks to the highly negative surface charge of the vesicles (~−33 mV). The cryo-TEM images confirmed the formation of close-packed, oligolamellar and multicompartment hyalurosomes and glycerohyalurosomes in which around 95% of the used extract was retained, confirming their ability to simultaneously load a wide range of molecules having different chemical natures. Moreover, the extract, when loaded in hyalurosomes and glycerohyalurosomes was able to counteract the damages induced in the fibroblasts by hydrogen peroxide to a better extent (viability~110%) than that loaded in the other vesicles (viability~100%), and effectively promoted their proliferation and migration ensuring the healing of the wound performed in a cell monolayer (scratch assay) during 48 h of experiment. Overall in vitro results confirmed the potential of glycerohyalurosomes as delivery systems for T. marum extract for the treatment of skin lesions connected with oxidative stress.

Abstract
Topical drug delivery is a promising approach to treat different skin disorders. However, it remains a challenge mainly due to the nature and rigidity of the nanosystems, which limit deep skin penetration, and the unsuccessful demonstration of clinical benefits; greater penetration by itself, does not ensure pharmacological success. In this context, transfersomes have appeared as promising nanosystems; deformability, their unique characteristic, allows them to pass through the epidermal microenvironment, improving the skin drug delivery. This review focuses on the comparison of transfersomes with other nanosystems (e.g., liposomes), discusses recent therapeutic applications for the topical treatment of different skin disorders and highlights the need for further studies to demonstrate significant clinical benefits of transfersomes compared with conventional therapies.

[PMID: 34391852 DOI: 10.1016/j.ijpharm.2021.121010] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2021] [Revised: 08/10/2021] [Accepted: 08/10/2021] [Indexed: 12/15/2022]
Abstract
Cytomegalovirus (CMV) retinitisis a vision-threatening disease that principally afflicts immunosuppressed patients. For the management of the disease, Ganciclovir (GCV) is usually administered systemically, where patients may suffer severe untoward effects. The ocularly-applied alternatives are either the intravitreal injections, which are frequently administered due to GCV short half-life, or the sustained-release implants, which require surgical removal upon drug depletion. Both therapies are invasive and should be completed by a medical expert. The objective of this research was to formulate a non-invasive alternative represented in GCV loaded ultra-fluidic glycerosomes (UFGs), which are glycerosomes containing sodium taurocholate as an edge activator (EA), then incorporating the optimal UFGs in polylactic acid (PLA)-based 3D printed ocusert to prolong the release of GCV. The experimental design, the statistical analysis, and the optimization were performed via Design-Expert® software. The optimal formulation (UFGs 6; composed of 600 mg Phosphatidylcholine (PC), 20 mg cholesterol, 0.1:1 weight molar ratio of EA: PC and 1 gm glycerol) possessed nanovesicles (441.70 ± 1.13 nm) that entrapped 69.33 ± 0.28 % of GCV, with zeta potential value of -37.00 ± 0.42 mV and deformability index value of 74.68 ± 0.71. The confocal microscopy results showed the supreme penetration power of UFGs through the rabbit's cornea, compared to edge-activated vesicles and conventional glycerosomes from the laden ocusert. Moreover, the topical application of the ocusert laden with the optimal GCV loaded UFGs to the rabbits' eyes evidenced their safety as per the histopathological findings. Furthermore, a pharmacokinetic study in the rabbit's aqueous humor demonstrated the sustained release of GCV from the ocusert laden with the optimal GCV loaded UFGs over 5 days. Inclusively, the ocusert laden with UFGs could be considered as a non-invasive sustaining drug delivery system of GCV for the management of CMV retinitis.

Abstract
Leishmaniasis is a human and animal disease endemic in tropical and subtropical areas treated by means of pentavalent antimony as first-line approach. Unfortunately, the formulations available on the market are characterized by significant side effects and a total remission of the disease is difficult to be obtained. The aim of this investigation is to describe the development and characterization of aqueous-core poly-l-lactide (PLA) nanocapsules containing glucantime (meglumine antimoniate, MA) with the aim of increasing the pharmacological efficacy of the active compound. The polymeric systems characterized by a mean diameter of ≈300 nm exert a great interaction with murine macrophages. MA-loaded PLA nanocapsules show a great antileishmanial activity on mice infected with Leishmania infantum with respect to the free drug, favoring a decrease of the administration times. The biodistribution profiles demonstrate a lower renal accumulation of MA after its nanoencapsulation and a significant increase of its plasmatic half-life. The parasite load evaluated by immunohistochemistry shows a significant decrease in liver, spleen, and kidneys when mice are treated with MA-loaded PLA nanocapsules especially after 45 days. The obtained results demonstrate the potential application of MA-loaded PLA nanocapsules as novel nanomedicine for the treatment of leishmaniasis.

Abstract
In the last decade, the attention of the scientific community has been focused on bile acids and their salts as systems for the transportation of drugs; specifically their role as carriers and integration into nanomedicine. Bile acids can play a critical role as drug carriers in the form of chemical conjugates, complexation, mixed micelles formation as well as stabilized bile acid liposomes (bilosomes). The unique molecular structure and interaction of these amphiphilic-steroidal compounds make them an interesting subject of research. This review is based on literature research in order to emphasize the importance of bile acids and their salts as absorption modulators in order to improve therapeutic potentials of low bioavailability drugs.

Abstract
Developing topical sildenafil for local treatment of erectile dysfunction has been of great interest in pharmaceutical research. Sildenafil citrate (SC) exhibited a well-documented success for treatment of several types of erectile dysfunction. However, its oral use is limited by serious adverse effects, poor bioavailability, delayed onset, and drug-drug interactions. This work is the first to design and assess sildenafil-loaded bilosomes for topical local treatment of erectile dysfunction. Different sildenafil-loaded bilosomes were prepared and characterized. Permeability of selected formulations was conducted through full-thickness human skin. Optimized bilosomes integrating sodium tauroglycocholate (STGC) showed spherical shape with good particle size (133 nm), high zeta potential (-53.6 mV) and high entrapment efficiency (87.45%). Ex-vivo permeability study revealed that about 39% of the applied dose permeated within 15 min. Furthermore, in-vivo appraisal of therapeutic efficacy was performed using aged male Sprague-Dawley rats. After single application of 2 mg/kg sildenafil loaded in STGC-bilosomes, behavioral and biochemical evaluation was carried out. Behavioral assessment recorded an increased rats' potency manifested as 2 folds increase in intromission frequency and intromission ratio compared to untreated group. That was accompanied by significant increase in cGMP concentration in corpora cavernosa (P < 0.0001) confirming increased potency. In conclusion, STGC-bilosomes could provide topical treatment of impotence with 20% of the oral dose and fast onset of action (10 min).

Abstract
The topical route of administration has many advantages for the treatment of various skin disorders as well as cosmeceutical purposes. This route bypasses hepatic first-pass effect and systemic availability of many pharmaceuticals is limited to skin organelles such as hair follicles and so could avoid unwanted adverse reactions and increase the localized therapeutic effect. Despite such attributed advantages of the topical route, the most important challenge is skin barrier characteristics that should be overcome to obtain dermal or trans-dermal drug delivery. Different approaches have been recruited to overcome this barrier. In this review, different types of nanoparticles for skin permeation enhancement and targeted delivery to skin organelles are discussed. The potential mechanisms of each nanocarrier in permeation enhancement and dermal delivery are considered and finally, the most important advantages and disadvantages of each group are summarized.

Abstract
PURPOSE Lecithin/chitosan nanoparticles have shown great promise in the transdermal delivery of therapeutic agents. Baicalein, a natural bioactive flavonoid, possesses multiple biological activities against dermatosis. However, its topical application is limited due to its inherently poor hydrophilicity and lipophilicity. In this study, the baicalein-phospholipid complex was prepared to enhance the lipophilicity of baicalein and then lecithin/chitosan nanoparticles loaded with the baicalein-phospholipid complex were developed to improve the transdermal retention and permeability of baicalein. METHODS Lecithin/chitosan nanoparticles were prepared by the solvent-injection method and characterized in terms of particle size distribution, zeta potential, and morphology. The in vitro release, the ex vivo and in vivo permeation studies, and safety evaluation of lecithin/chitosan nanoparticles were performed to evaluate the effectiveness in enhancing transdermal retention and permeability of baicalein. RESULTS The lecithin/chitosan nanoparticles obtained by the self-assembled interaction of chitosan and lecithin not only efficiently encapsulated the drug with high entrapment efficiency (84.5%) but also provided sustained release of baicalein without initial burst release. Importantly, analysis of the permeation profile ex vivo and in vivo demonstrated that lecithin/chitosan nanoparticles prolonged the retention of baicalein in the skin and efficiently penetrated the barrier of stratum corneum without displaying skin irritation. CONCLUSION These results indicate the potential of drug-phospholipid complexes in enhancing the entrapment efficiency and self-assembled lecithin/chitosan nanoparticles based on phospholipid complexes in the design of a rational transdermal delivery platform to improve the efficiency of transdermal therapy by enhancing its percutaneous retention and penetration in the skin.

Abstract
Glycyrrhiza glabra L. is a native plant of Central and South-Western Asia that is also diffused in the Mediterranean area and contains several bioactive compounds such as: flavonoids, sterols, triterpene and saponins. Glycyrrhizin, containing glycyrrhizic and glycyrrhizinic acids has anti-inflammatory and antiallergic effects that are similar to corticosteroids. Ammonium glycyrrhizinate is a derivative salt of glycyrrhizic acid with similar anti-inflammatory activity that cannot pass through the skin due to its physicochemical properties and molecular weight. Although several nanoformulations, such as ethosomes, are designed to provide a systemic effect through a topical application, there are different limitations to the distribution inside the blood stream. For this reason, ultradeformable liposomes, or transfersomes, are selected to improve the topical delivery of drugs and allow the distribution of payloads in the blood stream because they pass intact through the stratum corneum epidermis barrier, due to the presence of sodium cholate, aqueous cutaneous gradient, and the rapid penetration of transfersomes by cutaneous tight junctions, thus allowing the systemic delivery of different therapeutic cargo in non-occlusive conditions. The aim of this work was the synthesis and physicochemical characterization of the ammonium glycyrrhizinate-loaded ultradeformable liposomes, the evaluation of drug release and permeation through stratum corneum and epidermis barrier. The in vivo anti-inflammatory effect of ammonium glycyrrhizinate-loaded ultradeformable liposomes was tested on human healthy volunteers. The results demonstrated that the ammonium glycyrrhizinate-loaded ultradeformable liposomes decreased the skin inflammation on the human volunteers and the resulting nanoformulations can be used as a potential topical drug delivery system for anti-inflammatory therapy. ☆Parts of these results were presented as a poster communication at the Recent Developments in Pharmaceutical Analysis 2019 (RDPA 2019), Chieti, Italy.

Abstract
Background: Centella asiatica, a medicinal plant, has been used traditionally to promote wound healing. Its efficacy on promoting postlaser resurfacing wound healing is lacking. Methods: Thirty individuals with facial acne scars underwent a treatment with 2940 nm Er:YAG laser. Half side of the face was randomized to receive 0.05% w/w ECa 233 gel, a standardized extract of C. asiatica, and the other half a placebo gel. The gels were applied four times daily for 7 days then twice daily for 3 months. Erythema, melanin, and texture index (TI) from Antera3D,® and skin biophysics were obtained at baseline, days 2, 4, and 7, then every 2 weeks for the first month, and every month for 3 months. Three blinded dermatologists assessed the photographs and provided a grading scale of wound appearances. Results: The ECa 233 treated side exhibited significantly less erythema index over total follow-up by 0.03 U (coefficient = -0.03 [95% CI -0.06 to -0.0006]; p = 0.046). In keeping with the physicians' assessment that showed significantly higher improvements in skin erythema at days 2, 4, and 7 (p = 0.009, 0.0061, 0.012), crusting at days 2 (p = 0.02), and general wound appearance at days 2, 4, and 7 (p = 0.008, 0.001, 0.044), TI showed a trend toward better outcome in the ECa 233 group. Skin biophysics did not differ between the two groups. Conclusion: ECa 233 might be an option for postlaser treatment to improve wound appearance.

Abstract
Niosomes, liposomes and proniosomes are the most abundantly used vesicular systems for the transdermal delivery of drugs. Proniosomes are nonhydrated niosomes, which, upon hydration, form niosomes. Various researches have proved the advantages of proniosomes over the other conventional dosage forms currently available in the market. Proniosomes overcome physical stability problems involved with other vesicular systems such as leaking, fusion and aggregation. The stability and shelf life of proniosomes especially have been found to be much better and prolonged in comparison to other vesicular systems such as liposomes. The present review has been written in an effort to bring yet another viewpoint from a different angle and curated to compile the latest updates in this highly attractive delivery system from today's research point.

Abstract
Diabetic ulcers, gangrene, local infections and other traumatic symptoms of wound healing are all directly related. Promoting the early healing of diabetic cutaneous ulcers (DCU) and reducing the disability and treatment costs is an important research project integrating traditional Chinese and Western medicine. Nitric oxide (NO) is a key component of wound healing, and endogenous NO secretion is insufficient during the development of DCU. It has been reported that exogenous NO can promote wound healing, but exogenous NO has a short half-life and is difficult to adhere to the skin. Asiaticoside (AC) is extracted from the traditional Chinese medicine Centella asiatica, and has angiogenic, anticancer, antioxidant, anti-inflammatory, and wound-healing effects. Therefore, our study is based on the hypothesis that the combination of AC and NO to treat DCU is possible. In this study we considered gels of AC and NO, and evaluated the effects of the gel on DCU healing. Based on our study, it was found that the combined effect of asiaticoside and NO could accelerate the healing rate of DCU wounds. The asiaticoside NO gel can inhibit the growth of bacteria in the wound surface, alleviate the inflammatory reaction of wound, and increase the expression of VEGF, iNOS, eNOS and CD34. Our research shows that asiaticoside NO gel may promote DCU wound healing by regulating Wnt/β-Catenin signaling pathway. It will provide new targets and strategies for the diagnosis and treatment of DCU.

Abstract
The aim of this work was to evaluate the effect of two chemically different edge activators, i.e., Tween® 80 and sodium deoxycholate, on (i) the physical, mechanical, and biological properties of ultradeformable vesicles, and (ii) the administration of naproxen sodium-loaded multidrug ultradeformable vesicles for the transdermal route in order to obtain therapeutically meaningful drug concentrations in the target tissues and to potentiate its anti-inflammatory effect by association with the antioxidant drug idebenone. The results obtained in this investigation highlighted a synergistic action between naproxen and idebenone in the treatment of inflammatory disease with a more pronounced anti-inflammatory effect in multidrug ultradeformable vesicles compared to the commercial formulation of Naprosyn® gel. Systems made up of Tween® 80 appeared to be the most suitable in terms of percutaneous permeation and anti-inflammatory activity due to the greater deformability of these vesicles compared to multidrug ultradeformable vesicles with sodium deoxycholate. Our findings are very encouraging and suggest the use of these carriers in the topical treatment of inflammatory diseases.

Abstract
Cosmeceuticals are innovative emerging health and beauty aid products that combine the benefits of
cosmetic active ingredients and often innovative technological solutions of formulation and delivery. For decades,
phytocompounds have been used in cosmetics as sunscreen, moisturizing, antiaging, and skin-based therapy.
When compared to synthetic cosmetic ingredients, phytocompounds are generally milder, have a more favourable
toxicity profile, and are biodegradable. The major concerns in the usage of phytocompounds are their low solubility,
low penetration and physico-chemical instability when applied on the skin. To overcome these issues, different
nanotechnology-based systems have been proposed and some of them are already on the market. Nanotechnologies
can improve the solubility of poorly water-soluble compounds, facilitate skin permeation and increase
their stability against light and temperature. Liposomes, solid lipid nanoparticles, transfersomes, ethosomes,
nanostructured lipid carriers, and cyclodextrins are examples of nanotechnology-based systems currently in use to
improve the performances of phytocompounds in skin care. This review focuses on cosmeceuticals that explore
nanotechnology-based systems for the delivery of phytocompounds and emphasizes how these approaches can
improve product performances with respect to conventional cosmetic formulations.

Abstract
Essential oils are natural products with a complex composition. Terpenes are the most common class of chemical compounds present in essential oils. Terpenes and the essential oils containing them are widely used and investigated by their pharmacological properties and permeation-enhancing ability. However, many terpenes and essential oils are sensitive to environmental conditions, undergoing volatilization and chemical degradation. In order to overcome the chemical instability of some isolated terpenes and essential oils, the encapsulation of these compounds in nanostructured systems (polymeric, lipidic, or molecular complexes) has been employed. In addition, nanoencapsulation can be of interest for pharmaceutical applications due to its capacity to improve the bioavailability and allow the controlled release of drugs. Topical drug administration is a convenient and non-invasive administration route for both local and systemic drug delivery. The present review focuses on describing the current status of research concerning nanostructured delivery systems containing isolated terpenes and/or essential oils designed for topical administration and on discussing the use of terpenes and essential oils either for their biological activities or as permeation enhancers in pharmaceutic formulations.

Abstract
Polyurethane foam dressings for dermal wounds were formulated with natural polyols in order to improve the foam characteristics and the release of 2 active agents, silver and asiaticoside (AS) as an antimicrobial agent and an herbal wound healing agent, respectively. The foam was instantly formed by interaction of polyols and diisocyanate. Hydroxypropyl methylcellulose, chitosan and sodium alginate were individually mixed with the main polyols, polypropylene glycol, in the formulation while the active components were impregnated into the obtained foam dressing sheets. Although the type and amount of the natural polyols slightly affected the pore size, water sorption-desorption profile and compression strength of the obtained foam sheets, a prominent effect was found in the release of both active components. Among natural polyols formulations, foam sheets with alginate showed the highest silver and AS release. Non-cytotoxicity of these foam sheets to human fibroblast cells was confirmed. Antimicrobial testing on four bacteria strains showed that 1 mg/cm2 silver in formulations with 6% of natural polyols and without natural polyols had sufficient content of the silver release with comparable inhibition zone and significantly larger zone than other formulations. In pig study, the foam dressing with 6% alginate, 1 mg/cm2 silver and 5% AS could improve wound healing in both the percentage of the wound closure and histological parameters of the dermal wound without any dermatologic reactions. In conclusion, this innovative foam dressing had potential to be a good candidate for wound treatment.

Abstract
In the recent decade, skin delivery (topical and transdermal) has gained an unprecedented popularity, especially due to increased incidences of chronic skin diseases, demand for targeted and patient compliant delivery, and interest in life cycle management strategies among pharmaceutical companies. Literature review of recent publications indicates that among various skin delivery systems, lipid-based delivery systems (vesicular carriers and lipid particulate systems) have been the most successful. Vesicular carriers consist of liposomes, ultradeformable liposomes, and ethosomes, while lipid particulate systems consist of lipospheres, solid lipid nanoparticles, and nanostructured lipid carriers. These systems can increase the skin drug transport by improving drug solubilization in the formulation, drug partitioning into the skin, and fluidizing skin lipids. Considering that lipid-based delivery systems are regarded as safe and efficient, they are proving to be an attractive delivery strategy for the pharmaceutical as well as cosmeceutical drug substances. However, development of these delivery systems requires comprehensive understanding of physicochemical characteristics of drug and delivery carriers, formulation and process variables, mechanism of skin delivery, recent technological advancements, specific limitations, and regulatory considerations. Therefore, this review article encompasses recent research advances addressing the aforementioned issues.

Abstract
All-trans retinoic acid (ATRA) is an anti-tumor compound, exerting different anti-cancer effects on different types of cancer cells. Unfortunately, retinoids are also characterized by certain side effects following systemic administration, such as the burning of skin and general malaise. The highly variable degree of bioavailability of ATRA plus its tendency to induce its own destruction through metabolic degradation following oral treatment necessitate the development of alternative formulations. The aim of this work is to evaluate the physico-chemical properties of unilamellar, ATRA-containing liposomes and to investigate the cytotoxic activity of this potential nanomedicine on human thyroid carcinoma cells. Liposomes made up of DPPC/Chol/DSPE-mPEG2000 (6:3:1 molar ratio), characterized by a mean diameter of ∼200nm, a polydispersity index of 0.1 and a negative surface charge, were used as ATRA-carriers and their antiproliferative efficacy was investigated in comparison with the free drug on three different human thyroid carcinoma cell lines (PTC-1, B-CPAP, and FRO) through MTT-testing. The liposomes protected the ATRA against photodegradation and increased its antiproliferative properties due to the improvement of its cellular uptake. ATRA-loaded liposomes could be a novel formulation useful for the treatment of anaplastic thyroid carcinoma.

Enhanced antioxidation via encapsulation of isooctyl p-methoxycinnamate with sodium deoxycholate-mediated liposome endocytosis. Int J Pharm 2015; 496:392-400.

Abstract
Isooctyl p-methoxycinnamate(OMC) is a commonly used chemical ultraviolet B sunscreen that suffers rapid degradation with current delivery systems following sun exposure. In this study, deoxycholate-mediated liposome (DOC-LS) endocytosis was employed to improve the antioxidation effects of OMC following topical administration, and the in vitro cell uptake was investigated to understand the enhanced cutaneous absorption of the drug via this nanocarrier. Following topical application, structural changes in the stratum corneum were identified. With the increase of DOC content, the drug deposition in skin decreased; from this, a DOC-LS formulation was selected that showed significantly more drug delivery in skin than did the other preparations (P<0.05). DOC-LS decreased skin resistance, suggesting its ability to induce skin barrier disruption. In vitro HaCaT keratinocyte cell uptake of coumarin-6 incorporated in the two types of phosphatidylcholine (PC) vesicles (i.e., LS or DOC-LS) yielded similar fluorescence intensities following incubation for different periods (P<0.05). However, CCC-ESF-1 embryonic fibroblast cell uptake of the fluorescence revealed time-dependence, and the emitted light from DOC-LS incubated cells was stronger than that from cells incubated with LS (P<0.05). These findings might be associated with the endocytic pathway of HaCaT, which mainly exhibited adsorption or physical adhesion of the fluorescent vesicles, whereas CCC-ESF-1 markedly internalized the PC vesicles via the lysosomes, as shown by intracellular fluorescence co-location studies. Following loading with the same amount of OMC, the DOC-LS vesicles exhibited superior skin tissue antioxidative capacity among the preparations tested, corroborating the in vivo skin drug deposition results. Thus, our results suggest that DOC-LS is a promising system for OMC dermal delivery without promoting skin irritation, which is quite advantageous for therapeutic purposes.

[PMID: 26321058 DOI: 10.1016/j.biomaterials.2015.08.034] [Citation(s) in RCA: 139] [Impact Index Per Article: 15.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2015] [Revised: 08/08/2015] [Accepted: 08/14/2015] [Indexed: 02/02/2023]
Abstract
In the present work new highly biocompatible nanovesicles were developed using polyanion sodium hyaluronate to form polymer immobilized vesicles, so called hyalurosomes. Curcumin, at high concentration was loaded into hyalurosomes and physico-chemical properties and in vitro/in vivo performances of the formulations were compared to those of liposomes having the same lipid and drug content. Vesicles were prepared by direct addition of dispersion containing the polysaccharide sodium hyaluronate and the polyphenol curcumin to a commercial mixture of soy phospholipids, thus avoiding the use of organic solvents. An extensive study was carried out on the physico-chemical features and properties of curcumin-loaded hyalurosomes and liposomes. Cryogenic transmission electron microscopy and small-angle X-ray scattering showed that vesicles were spherical, uni- or oligolamellar and small in size (112-220 nm). The in vitro percutaneous curcumin delivery studies on intact skin showed an improved ability of hyalurosomes to favour a fast drug deposition in the whole skin. Hyalurosomes as well as liposomes were biocompatible, protected in vitro human keratinocytes from oxidative stress damages and promoted tissue remodelling through cellular proliferation and migration. Moreover, in vivo tests underlined a good effectiveness of curcumin-loaded hyalurosomes to counteract 12-O-tetradecanoilphorbol (TPA)-produced inflammation and injuries, diminishing oedema formation, myeloperoxydase activity and providing an extensive skin reepithelization. Thanks to the one-step and environmentally-friendly preparation method, component biocompatibility and safety, good in vitro and in vivo performances, the hyalurosomes appear as promising nanocarriers for cosmetic and pharmaceutical applications.

Abstract
Excessive production of radical oxygen species in skin is a contributor to a variety of skin pathologies. Naringenin is a potent antioxidant. The purpose of the present study was to develop elastic liposomes for naringenin topical application. Naringenin-loaded elastic liposomes containing different amounts of Tween 80 and cholesterol were prepared. The physicochemical properties including vesicle size, surface charge, encapsulation efficiency, and permeability capacity were determined to evaluate the effect of components. The stability of formulation and skin irritation caused by drug-loaded elastic liposomes were also evaluated for assessment of the clinical utility of elastic liposomes. Saturated aqueous solution of naringenin and naringenin dissolved in 10% Tween 80 solution (5 mg/mL) were used as the control group. The result showed that in using elastic liposomes as carrier, the deposition amounts in the skin of naringenin were significantly increased about 7.3~11.8-fold and 1.2~1.9-fold respectively, when compared with the saturated aqueous solution and Tween 80 solution-treated groups. The level of drug was more than 98.89±3.90% after 3 months of storage at 4℃. In a skin irritation test, the result showed experimental formulation exhibit considerably less irritating than the positive control (paraformaldehyde-treated) group, suggesting its potential therapeutic application.

Abstract
The human body has long provided pharmaceutical science with biomaterials of interesting applications. Bile salts (BSs) are biomaterials reminiscent of traditional surfactants with peculiar structure and self-assembled topologies. In the pharmaceutical field, BSs were employed on the basis of two different concepts. The first concept exploited BSs' metabolic and homeostatic functions in disease modulation, whereas the second one utilized BSs' potential to modify drug-delivery characteristics, which recently involved nanotechnology. This review is the first to gather major pharmaceutical applications of BSs from endogenous organotropism up to integration into nanomedicine, with a greater focus on the latter domain. Endogenous applications highlighted the role of BS in modulating hypercholesterolemia and cancer therapy in view of enterohepatic circulation. In addition, recent BS-integrated nanomedicines have been surveyed, chiefly size-tunable cholate nanoparticles, BS-lecithin mixed micelles, bilosomes, probilosomes, and surface-engineered bilosomes. A greater emphasis has been laid on nanosystems for vaccine and cancer therapy. The comparative advantages of BS-integrated nanomedicines over conventional nanocarriers have been noted. Paradoxical effects, current pitfalls, future perspectives, and opinions have also been outlined.

Abstract
PURPOSE To synthesize a new polymeric prodrug based on α,β-poly(N-2-hydroxyethyl)(2-aminoethylcarbamate)-d,l-aspartamide copolymer bearing amine groups in the side chain (PHEA-EDA), covalently linked to the anticancer drug doxorubicin and to test its potential application in anticancer therapy. METHODS The drug was previously derivatized with a biocompatible and hydrophilic linker, leading to a doxorubicin derivative highly reactive with amino groups of PHEA-EDA. The PHEA-EDA-DOXO prodrug was characterized in terms of chemical stability. The pharmacokinetics, biodistribution and cytotoxicity of the product was investigated in vitro and in vivo on human breast cancer MCF-7 and T47D cell lines and NOD-SCID mice bearing a MCF-7 human breast carcinoma xenograft. Data collected were compared to those obtained using free doxorubicin. RESULTS The final polymeric product is water soluble and easily hydrolysable in vivo, due to the presence of ester and amide bonds along the spacer between the drug and the polymeric backbone. In vitro tests showed a retarded cytotoxic effect on tumor cells, whereas a significant improvement of the in vivo antitumor activity of PHEA-EDA-DOXO and a survival advantage of the treated NOD-SCID mice was evidenced, compared to that of free doxorubicin. CONCLUSIONS The features of the PHEA-EDA-DOXO provide a potential protection of the drug from the plasmatic enzymatic degradation and clearance, an improvement of the blood pharmacokinetic parameters and a suitable body biodistribution. The data collected support the promising rationale of the proposed macromolecular prodrug PHEA-EDA-DOXO for further potential development and application in the treatment of solid cancer diseases.

Abstract
The aim of the present study was to elucidate the polyphenolic composition of Fraxinus angustifolia leaf and bark extracts, and to evaluate their efficacy in wound healing. Quercetin, catechin, rutin and tannic acid were identified as the main components of the extracts. In order to improve their skin bioavailability, the polyphenolic phytocomplexes were incorporated in different nanovesicles, namely ethosomes and phospholipid vesicles containing Transcutol(®) P (Trc) or ethylene glycol (EG). The latter had never been used before as a component of phospholipid vesicles, and it was found to play a key role in improving extract efficacy in wound healing. Results of cryogenic transmission electron microscopy (cryo-TEM), Photon Correlation Spectroscopy (PCS) and Small-Angle X-ray Scattering (SAXS) showed that ethosomes and EG-PEVs were small, monodispersed, unilamellar vesicles, while Trc-PEVs were larger, less homogeneously dispersed and multilamellar, with a large bilayer thickness. Free extracts did not show relevant ability to protect in vitro human keratinocytes from H2O2 damages, while when entrapped in nanovesicles, they significantly inhibited H2O2 stress damages, probably related to a higher level of cell uptake. On the other hand, in vivo results showed that the highest antioxidant and anti-inflammatory effects were provided by the phytocomplexes in EG-PEVs, which favoured wound healing. Moreover, non-entrapped F. angustifolia extracts showed a marginal effect, comparable to that of free quercetin dispersion (control). In conclusion, our results depict that these extracts may find potential applications in biomedicine.

Abstract
The aim of this study was the evaluation of the effects of two emulsifiers on the physicochemical and technological properties of low molecular weight chitosan/poly (D,L-lactide-co-glycolide) (PLGA) nanoplexes and their transfection efficiency. Nanospheres were prepared using the nanoprecipitation method of the preformed polymer. The mean diameter and surface charge of the nanospheres were investigated by photocorrelation spectroscopy. The degree of binding of the plasmid with the nanoplexes was qualitatively and quantitatively determined. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) testing was performed using HeLa, RPMI8226, and SKMM1 cell lines. Flow cytometry and confocal laser scanning microscopy were used to determine the degree of cellular transfection and internalization of the nanoplexes into cells, respectively. The nanoplexes had a positive zeta potential, and low amounts of PLGA and poloxamer 188 showed a mean colloidal size of ~200 nm with a polydispersity index of ~0.14. The nanoplexes had suitable entrapment efficiency (80%). In vitro experiments showed that the colloidal nanodevices did not induce significant cytotoxicity. The nanoplexes investigated in this study could represent efficient and useful nonviral devices for gene delivery. Use of low amounts of PLGA and poloxamer 188 enabled development of a nanosphere able to transfect cells efficiently. These nanosystems are a helpful platform for delivery of genetic material while preserving therapeutic efficacy.

Abstract
BACKGROUND Cellulite is a serious cosmetic concern for most of the 90% of women affected by it. OBJECTIVE To assess the clinical efficacy of a complex integral anti-cellulite gel. METHODS This double-blind, randomized, placebo-controlled study involved 44 healthy women, aged 25-55 years. Subjects had a normal to slightly overweight body mass index and presented slight to moderate cellulite on their thighs, buttocks, and/or hips at baseline. Subjects were randomly assigned to either the treated or placebo group and accordingly applied the active product or placebo on their hips, stomach, buttocks, and thighs, twice daily for 3 months. Skin tonicity, orange-peel aspect, and stubborn cellulite were assessed at day 0, 28, 56, and 84. A self-evaluation questionnaire was completed by all volunteers. RESULTS At the end of the study, an average of 81% of the subjects applying the active product presented improvement in their cellulite condition versus 32% for the placebo group (all descriptors and sites combined). At day 84, skin tonicity, orange-peel appearance, and stubborn cellulite were improved in a significant manner (P<0.05) over placebo, on all studied areas. Skin tonicity improved on average by +41% for buttocks, +35% for hips, and +31% for thighs. Orange peel appearance was reduced on average by -25% for buttocks, -22% for hips, and -22% for thighs. Stubborn cellulite was reduced on average by -19% for buttocks, -24% for hips, and -22% for thighs. Circumference measurements decreased in a significant manner (P<0.05) over placebo, for the abdomen (average value of -1.1 cm) and thighs (average value of -0.8 cm). The product was well tolerated and perceived by the volunteers themselves as better performing than placebo on all criteria. CONCLUSION All results validate the efficacy of the present integral formulation to significantly reduce signs of cellulite and reshape the silhouette.

Abstract
BACKGROUND Liquorice extracts demonstrate therapeutic efficacy in treating dermatitis, eczema, and psoriasis when compared with corticosteroids. In this work, nonionic surfactant vesicles (niosomes, NSVs) containing polysorbate 20 (Tween 20), cholesterol, and cholesteryl hemisuccinate at different molar concentrations were used to prepare monoammonium glycyrrhizinate (AG)-loaded NSVs. The anti-inflammatory properties of AG-loaded NSVs were investigated in murine models. METHODS The physicochemical properties of the NSVs were characterized using dynamic light scattering. The fluidity of the lipid bilayer was evaluated by measuring the fluorescence intensity of diphenylhexatriene. The drug entrapment efficiency of AG was assessed using high-performance liquid chromatography. The physicochemical stability of the NSVs was evaluated as a function of time using dynamic light scattering combined with Turbiscan Lab Expert analysis. Serum stability was determined by incubating the NSVs with 10% v/v fetal bovine serum. The cytotoxic effects of the NSVs were investigated in human dermal fibroblasts using the Trypan blue dye exclusion assay (for cell mortality) and an MTT assay (for cell viability). Release profiles for the AG-loaded NSVs were studied in vitro using cellulose membranes. NSVs showing the most desirable physicochemical properties were selected to test for in vivo anti-inflammatory activity in murine models. The anti-inflammatory activity of the NSVs was investigated by measuring edema and nociception in mice stimulated with chemical agents. RESULTS NSVs showed favorable physicochemical properties for in vitro and in vivo administration. In addition, they demonstrated long-term stability based on Turbiscan Lab Expert analysis. The membrane fluidity of the NSVs was not affected by self-assembling of the surfactants into colloidal structures. Fluorescence anisotropy was found to be independent of the molar ratios of cholesteryl hemisuccinate and/or cholesterol during preparation of the NSVs. The anti-inflammatory AG drug showed no effect on the stability of the NSVs. In vivo experiments demonstrated that AG-loaded NSVs decreased edema and nociceptive responses when compared with AG alone and empty NSVs. In vitro and in vivo results demonstrated that pH sensitive and neutral NSVs show no statistical significant difference. CONCLUSION NSVs were nontoxic and showed features favorable for potential administration in vivo. In addition, neutral NSVs showed signs of increased anti-inflammatory and antinociceptive responses when compared with AG.
