Kadry MO, Abdel-Megeed RM. CRISPR-Cas9 genome and long non-coding RNAs as a novel diagnostic index for prostate cancer therapy via liposomal-coated compounds. PLoS One 2024; 19:e0302264. [PMID: 38723038 PMCID: PMC11081254 DOI: 10.1371/journal.pone.0302264] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 03/31/2024] [Indexed: 05/13/2024] Open
Abstract
CRISPR/Cas9 is a recently discovered genomic editing technique that altered scientist's sight in studying genes function. Cas9 is controlled via guide (g) RNAs, which match the DNA targeted in cleavage to modify the respective gene. The development in prostate cancer (PC) modeling directed not only to novel resources for recognizing the signaling pathways overriding prostate cell carcinoma, but it has also created a vast reservoir for complementary tools to examine therapies counteracting this type of cancer. Various cultured somatic rat models for prostate cancer have been developed that nearly mimic human prostate cancer. Nano-medicine can passively target cancer cells via increasing bioavailability and conjugation via specific legend, contributing to reduced systemic side-effects and increased efficacy. This article highlights liposomal loaded Nano-medicine as a potential treatment for prostate cancer and clarifies the CRISPR/Cas9 variation accompanied with prostate cancer. PC is induced experimentally in western rat model via ethinyl estradiol for 4 weeks and SC. dose of 3, 2'- dimethyl-4-aminobiphenyl estradiol (DAE) (50mg/kg) followed by treatment via targeted liposomal-coated compounds such as liposomal dexamethasone (DXM), liposomal doxorubicin (DOX) and liposomal Turmeric (TUR) (3mg/kg IP) for four weeks in a comparative study to their non-targeted analogue dexamethasone, doxorubicin and Turmeric. 3, 2'- dimethyl-4-aminobiphenylestradiol elicit prostate cancer in western rats within 5 months. Simultaneous supplementations with these liposomal compounds influence on prostate cancer; tumor markers were investigated via prostate-specific antigen (PSA), Nitric oxide (NOX) and CRISPR/Cas9 gene editing. Several long non-coding RNAs were reported to be deregulated in prostate cell carcinoma, including MALAT1. On the other hand, gene expression of apoptotic biomarkers focal adhesion kinase (AKT-1), phosphatidylinistol kinase (PI3K) and glycogen synthase kinase-3 (GSK-3) was also investigated and further confirming these results via histopathological examination. Liposomal loaded dexamethasone; doxorubicin and Turmeric can be considered as promising therapeutic agents for prostate cancer via modulating CRISPR/Cas9 gene editing and long non coding gene MALAT1.

Abstract
Natural products have played a significant role throughout history in the prevention and treatment of numerous diseases, particularly cancers. As a natural product primarily derived from various medicinal plants in the Withania genus, withanolides have been shown in several studies to exhibit potential activities in cancer treatment. Consequently, understanding the molecular mechanism of withanolides could herald the discovery of new anticancer agents. Withanolides have been studied widely, especially in the last 20 years, and attracted the attention of numerous researchers. Currently, over 1200 withanolides have been classified, with approximately a quarter of them having been reported in the literature to be able to modulate the survival and death of cancer cells through multiple avenues. To what extent, though, has the anticancer effects of these compounds been studied? How far are they from being developed into clinical drugs? What are their potential, characteristic features, and challenges? In this review, we elaborate on the current knowledge of natural compounds belonging to this class and provide an overview of their natural sources, anticancer activity, mechanism of action, molecular targets, and implications for anticancer drug research. In addition, direct targets and clinical research to guide the design and implementation of future preclinical and clinical studies to accelerate the application of withanolides have been highlighted.

Abstract
For cancer therapy, paclitaxel (PX) possesses several limitations, including limited solubility and untargeted effects. Loading PX into nanoliposomes to enhance PX solubility and target their delivery as a drug delivery system has the potential to overcome these limitations. Over the other conventional method to prepare liposomes, a microfluidic system is used to formulate PX-loaded PEGylated liposomes. The impact of changing the flow rate ratio (FRR) between the aqueous and lipid phases on the particle size and polydispersity index (PDI) is investigated. Moreover, the effect of changing the polyethylene glycol (PEG) lipid ratio on the particle size, PDI, stability, encapsulation efficiency % (EE %), and release profile is studied. The physicochemical characteristics of the obtained formulation were analyzed by dynamic light scattering, FTIR spectroscopy, and AFM. This work aims to use microfluidic technology to produce PEGylated PX-loaded liposomes with a diameter of <200 nm, low PDI < 0.25 high homogeneity, and viable 28 day stability. The results show a significant impact of FRR and PEG lipid ratio on the empty liposomes' physicochemical characteristics. Among the prepared formulations, two formulations produce size-controlled, low PDI, and stable liposomes, which make them preferable for PX encapsulation. The average EE % was >90% for both formulations, and the variation in the PEG lipid ratio affected the EE % slightly; a high packing for PX was reported at different drug concentrations. A variation in the release profiles was notified for the different PEG lipid ratios.

Abstract
tLyP-1 peptide is verified to recognize neuropilin (NRP) receptors overexpressed on the surface of both glioma cells and endothelial cells of angiogenic blood vessels. In the present study, tLyP-1 was conjugated with DSPE-PEG2000 to prepare tLyP-1-DSPE-PEG2000, which was further employed to prepare tLyP-1 functionalized nanoliposome (tLyP-1-Lip) to achieve enhancing target of glioblastoma. Process parameters were systematically studied to investigate the feasibility of tuning the internal water phase of nanoliposomes and encapsulating more Temozolomide (TMZ). The particle size, Zeta potential, and encapsulation efficiency of tLyP-1-Lip/TMZ were fully characterized in comparison with conventional nanoliposomes (Lip-TMZ) and PEGylated nanoliposomes (PEG-Lip/TMZ). The release behaviors of TMZ from PEG-Lip/TMZ and tLyP-1-Lip/TMZ are similar and slower than TMZ-Lip in acidic solutions. The tLyP-1-Lip/TMZ demonstrated the strongest cytotoxicity in comparison with TMZ-Lip and PEG-Lip/TMZ in both U87 and HT22 cells, and displayed the highest cellular internalization. The pharmacokinetic studies in rats revealed that tLyP-1-Lip/TMZ showed a 1.4-fold (p < 0.001) increase in AUCINF_obs and a 1.4-fold decrease (p < 0.01) in clearance compared with PEG-Lip/TMZ. We finally confirmed by in vivo imaging that tLyP-1-Lip were able to penetrate the brains and tumors of mice.

Abstract
Colorectal cancer (CRC) is a global health problem responsible for 10% of all cancer incidences and 9.4% of all cancer deaths worldwide. The number of new cases increases per annum, whereas the lack of effective therapies highlights the need for novel therapeutic approaches. Conventional treatment methods, such as surgery, chemotherapy and radiotherapy, are widely applied in oncology practice. Their therapeutic success is little, and therefore, the search for novel technologies is ongoing. Many efforts have focused recently on the development of safe and efficient cancer nanomedicines. Nanoparticles are among them. They are uniquewith their properties on a nanoscale and hold the potential to exploit intrinsic metabolic differences between cancer and healthy cells. This feature allows them to induce high levels of toxicity in cancer cells with little damage to the surrounding healthy tissues. Graphene oxide is a promising 2D material found to play an important role in cancer treatments through several strategies: direct killing and chemosensitization, drug and gene delivery, and phototherapy. Several new treatment approaches based on nanoparticles, particularly graphene oxide, are currently under research in clinical trials, and some have already been approved. Here, we provide an update on the recent advances in nanomaterials-based CRC-targeted therapy, with special attention to graphene oxide nanomaterials. We summarise the epidemiology, carcinogenesis, stages of the CRCs, and current nanomaterials-based therapeutic approaches for its treatment.

New carvacrol and thymol derivatives as potential insecticides: synthesis, biological activity, computational studies and nanoencapsulation. RSC Adv 2021; 11:34024-34035. [PMID: 35497284 PMCID: PMC9042360 DOI: 10.1039/d1ra05616f] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Accepted: 09/23/2021] [Indexed: 12/12/2022] Open
Abstract
New compounds with potential insecticide activity were synthesized by structural modifications performed in the monoterpenoid phenolic moieties of carvacrol and thymol, resulting in a set of derivatives with the ether function containing the propyl, chloropropyl or hydroxypropyl chains, as well as a bicyclic ether with an unsaturated chain containing a carboxylic acid terminal. In addition, an analogue of carvacrol and thymol isomers bearing methoxyl, 1-hydroxyethyl and (3-chlorobenzoyl)oxy, instead of the three original methyl groups, was also synthesized. Several structural changes that resulted in diminished insecticide activity have been identified, but two significantly active molecules have been synthesized, one of them being less toxic to human cells than the naturally-derived starting materials. Structure-based inverted virtual screening and molecular dynamics simulations demonstrate that these active molecules likely target the insect odorant binding proteins and/or acetylcholinesterase and are able to form stable complexes. For the most promising compounds, nanoencapsulation assays were carried out in liposomes of egg phosphatidylcholine/cholesterol (7 : 3) prepared by both thin film hydration and ethanolic injection methods. The compound-loaded liposomes were generally monodisperse and with sizes smaller than or around 200 nm. The thin film hydration method allowed high encapsulation efficiencies (above 85%) for both compounds and a delayed release, while for the systems prepared by ethanolic injection the encapsulation efficiency is lower than 50%, but the release is almost complete in two days.

Abstract
Colorectal cancer (CRC) is the third most frequently occurring tumor in the human population. CRCs are usually adenocarcinomatous and originate as a polyp on the inner wall of the colon or rectum which may become malignant in the due course of time. Although the therapeutic options of CRC are limited, the early diagnosis of CRC may play an important role in preventive and therapeutic interventions to decrease the mortality rate. The CRC-affected tissues exhibit several molecular markers that may be exploited as the novel strategy to develop newer approaches for the treatment of the disease. Nanotechnology consists of a wide array of innovative and astonishing nanomaterials with both diagnostics and therapeutic potential. Several nanomaterials and nano formulations such as Carbon nanotubes, Dendrimer, Liposomes, Silica Nanoparticles, Gold nanoparticles, Metal-organic frameworks, Core-shell polymeric nano-formulations, Nano-emulsion System, etc can be used to targeted anticancer drug delivery and diagnostic purposes in CRC. The light-sensitive photosensitizer drugs loaded gold and silica nanoparticles can be used to diagnose as well as the killing of CRC cells by the targeted delivery of anticancer drugs to cancer cells. This review is focused on the recent advancement of nanotechnology in the diagnosis and treatment of CRC.

Abstract
Withaferin A (WA) is a natural steroidal lactone with promising therapeutic applications. However, its clinical application is limited due to the low bioavailability and hydrophobic nature. In this study, we had prepared PEGylated nanoliposomal withaferin A (LWA) using thin-film hydration method. Dynamic light scattering, Transmission electron microscopy, and HPLC were used to investigate the impact of prepared formulations on the size, charge, morphology, and encapsulation efficiency of the LWA. The prepared nanoliposomal system had spherical vesicles, with the mean particle size of 125 nm and had an encapsulation efficiency of 83.65% with good stability. The characterization results indicated that nanoliposomal formulation is able to improve biocompatibility and bioavailability of WA. In vitro drug release study showed that LWA had an enhanced sustained drug release effect than the free drug. In vitro studies using ascites cell lines (DLA and EAC) showed that LWA treatment could induce apoptosis in ascites cells evidenced by acridine orange/ethidium bromide, Hoechst, and Giemsa staining. In vivo tumour study revealed that LWA treatment significantly reduced tumour growth and improved survival in DLA tumour bearing mice. In vivo results further demonstrated that LWA mitigated solid tumour development by regulating Ki-67 and cyclin D1 protein expression. The overall study results reveal that nanoliposome encapsulated WA exhibits therapeutic efficacy over WA in regulating tumour development as evidenced from ascites cell apoptosis as well as experimental tumour reduction studies.

Abstract
In recent years, the irrational use of antibiotics has escalated the evolution of multidrug-resistant (MDR) bacterial strains. The infectious diseases caused by these MDR bacterial strains remain a major threat to human health and have emerged as the leading cause of morbidity and mortality. The WHO and CDC have expressed serious concern regarding the continued increase in the development of multidrug resistance among bacteria. The antimicrobial resistance (AMR) poses a severe global threat of growing concern to human health and economic burden. Bacteria have developed the ability to resist antimicrobials by altering target site/enzyme, inactivation of the enzyme, decreasing cell permeability, increasing efflux due to over-expression of efflux pumps, target protection, target overproduction, and many other ways. The shortage of new antimicrobials and rapid rise in antibiotic resistance demands pressing need to develop alternate antibacterial agents.

Abstract
Leishmaniasis is a parasitic neglected tropical disease and result in a broad spectrum of clinical manifestations, ranging from a single ulceration to a progressive and fatal visceral disease. Comprising a limited and highly toxic therapeutic arsenal, new treatments are urgently needed. Targeting delivery of drugs has been a promising approach for visceral leishmaniasis (VL). Phosphatidylserine-liposomes have demonstrated superior efficacy in VL, targeting intracellular parasites in host cells through macrophage scavenger receptors. In this work, we investigated the in vitro and in vivo efficacy of the antihelminthic drug nitazoxanide in a nanoliposomal formulation against Leishmania (L.) infantum. Physicochemical parameters of liposomes containing nitazoxanide (NTZ-LP) were determined by dynamic light scattering and small angle X-ray scattering. The efficacy of the formulation was verified in an intracellular amastigote model and in an experimental hamster model. Our findings showed that NTZ-LP was able to eliminate the amastigotes inside the host cell with an IC50 value of 16 μM. NTZ-LP was labelled a fluorescent probe and by spectrofluorimetry, we observed that the infected macrophages internalized similar levels of the drug to the uninfected cells. The confocal microscopy images confirmed the uptake and demonstrated a diffuse distribution of the NTZ-LP in the cytoplasm of Leishmania-infected macrophages, with the vesicles in a closer proximity to the parasites. For the in vivo efficacy, the liposomal NTZ-LP was administrated intraperitoneally to Leishmania-infected hamsters for 10 consecutive days at 2 mg/kg/day. By qPCR we demonstrated a reduction of the parasite burden by 82% and 50% in the liver (p < 0.05) and spleen (p < 0.05), respectively. NTZ (non-liposomal) was administered at 100 mg/kg/day per oral (p.o.) for the same period, but demonstrated no efficacy. This liposomal formulation ensured a targeting delivery of NTZ to the intracellular parasites, resulting in an good efficacy at a low dose in animals, and it may represent a new candidate therapy for VL. Nanoliposomal nitazoxanide (NTZ-LP) eliminates amastigotes of Leishmania. The uptake of NTZ-LP by infected macrophages is similar to uninfected cells. NTZ-LP localizes in a closer proximity to the amastigotes inside the macrophages. NTZ-LP reduces the parasite burden by 82% (liver) and 50% (spleen) of hamsters.

[PMID: 32673771 DOI: 10.1016/j.ijpharm.2020.119647] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 07/08/2020] [Accepted: 07/09/2020] [Indexed: 01/09/2023]
Abstract
The topical delivery of nanotherapeutics at the injury site for skin regeneration has received increasing attention as a strategy for wound treatment. This study aimed to investigate the preparation of spray dried tadalafil loaded pro-nanoliposomes powder as a novel system to accelerate wound healing process. The optimization was carried out employing 32 factorial design based on phospholipid and cholesterol concentrations. The physicochemical characterizations, in vitro cellular assessment and in vivo performance were evaluated. The results obtained pointed out that phospholipid concentration presented a positive effect on the entrapment efficacy and particle size, while cholesterol hindered the entrapment efficacy yet presented a prominent influence on particle size. Moreover, the optimized formulation showed a sustained release, high zeta potential and uniform spherical particles indicating entrapment of tadalafil in its amorphous state as demonstrated by FTIR and XPRD results. Cell viability and in vitro scratch assay demonstrated no cytotoxicity on human fibroblast cell lines and the ability of the drug and optimized formulation to promote cell migration. In vivo wound healing studies revealed significantly higher wound closure rates for areas treated with optimized loaded-formulation (65.95±6.47%) compared to unloaded formulation (29.78±9.65%), free drug (38.87±11.44%) and sham group (10.22±5.11%). In the in vivo study, histopathological specimens supported the previous results with presentation of cascade of healing elements via the angiogenetic activity of tadalafil. These outcomes provide an insight of a novel and emerging therapeutic drug system for wound treatment in clinical practice.

Abstract
Nanoparticles have been extensively studied for drug delivery and targeting to specific organs. The functionalization of the nanoparticle surface by site-specific ligands (antibodies, peptides, saccharides) can ensure efficient recognition and binding with relevant biological targets. One of the main challenges in the development of these decorated nanocarriers is the accurate quantification of the amount of ligands on the nanoparticle surface. In this study, nanostructured lipid carriers (NLC) were functionalized with N-acetyl-D-galactosamine (GalNAc) units, known to target the asialoglycoprotein receptor (ASGPR). Different molar percentages of GalNAc-functionalized surfactant (0%, 2%, 5%, and 14%) were used in the formulation. Based on ultra-high-performance liquid chromatography separation and evaporative light-scattering detection (UPLC-ELSD), an analytical method was developed to specifically quantify the amount of GalNAc units present at the NLC surface. This method allowed the accurate quantification of GalNAc surfactant and therefore gave some insights into the structural parameters of these multivalent ligand systems. Our data show that the GalNAc decorated NLC possess large numbers of ligands at their surface and suitable distances between them for efficient multivalent interaction with the ASGPR, and therefore promising liver-targeting efficiency.

Abstract
Melanoma is an aggressive form of skin cancer, being one of the deadliest cancers in the world. The current treatment options involve surgery, radiotherapy, targeted therapy, immunotherapy and the use of chemotherapeutic agents. Although the last approach is the most used, the high toxicity and the lack of efficacy in advanced stages of the disease have demanded the search for novel bioactive molecules and/or efficient drug delivery systems. The current review aims to discuss the most recent advances on the elucidation of potential targets for melanoma treatment, such as aquaporin-3 and tyrosinase. In addition, the role of nanotechnology as a valuable strategy to effectively deliver selective drugs is emphasized, either incorporating/encapsulating synthetic molecules or natural-derived compounds in lipid-based nanosystems such as liposomes. Nanoformulated compounds have been explored for their improved anticancer activity against melanoma and promising results have been obtained. Indeed, they displayed improved physicochemical properties and higher accumulation in tumoral tissues, which potentiated the efficacy of the compounds in pre-clinical experiments. Overall, these experiments opened new doors for the discovery and development of more effective drug formulations for melanoma treatment.

Abstract
BACKGROUND Quercetin is a phenolic compound occurring in many food plants and agricultural crops. It is reported to possess various health-promoting properties. However, the poor bioavailability of quercetin, due to its low aqueous solubility and its degradation during digestion, limits its nutraceutical applications. This study aimed to encapsulate quercetin in nanoliposomes using rice-bran phospholipids for its efficient delivery and controlled release, the protection of its structural stability, and enhancement of its bioactivity. RESULTS Nanoliposomal encapsulation of quercetin by thin film-sonication method yielded spherical nanoparticles (157.33 ± 23.78 nm) with high encapsulation efficiency (84.92 ± 0.78%). Storage stability studies showed that nanoliposomal quercetin was stable at 4 °C and 27 °C for 6 and 5 months, respectively, as indicated by unchanged antioxidant activity and quercetin retention. Nanoliposomal quercetin showed a slow, limited release pattern in simulated gastric fluid (SGF), and an initial burst release followed by a slow constant releasing pattern in simulated intestinal fluid (SIF). A 1004-fold increase in 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging activity was observed in quercetin nanoliposomes (SC50 = 4.04 ± 0.01 ppm) compared to non-encapsulated quercetin (SC50 = 4053.03 ± 5.61 ppm). Similarly, the anti-angiogenic activity of quercetin, as evaluated by duck embryo chorioallantoic membrane (CAM) assay, was enhanced twofold to fivefold by nanoliposomal encapsulation. CONCLUSION This study showed that nanoliposomal encapsulation in rice-bran phospholipids enhanced the radical-scavenging and anti-angiogenic activities of quercetin. Furthermore, this study demonstrated that nanoliposomes can serve as efficient oral delivery system for quercetin. © 2018 Society of Chemical Industry.

Abstract
Oral cancer is among the most prevalent cancers in the world. Moreover, it is one of the major health problems and causes of death in many regions of the world. The traditional treatment modalities include surgical removal, radiation therapy, systemic chemotherapy, or a combination of these methods. In recent decades, there has been significant interest in intraoral site-specific chemoprevention via local drug delivery using polymeric systems. Because of its easy accessibility and clear visibility, the oral mucosa is amenable for local drug delivery. A variety of polymeric systems-such as gels, tablets, films, patches, injectable systems (e.g., millicylindrical implants, microparticles, and in situ-forming depots), and nanosized carriers (e.g., polymeric nanoparticles, nanofibers, polymer-drug conjugates, polymeric micelles, nanoliposomes, nanoemulsions, and polymersomes)-have been developed and evaluated for the local delivery of natural and synthetic chemopreventive agents. The findings of in vitro, ex vivo, and in vivo studies and the positive outcome of clinical trials demonstrate that intraoral site-specific drug delivery is an attractive, highly effective and patient-friendly strategy for the management of oral cancer. Intraoral site-specific drug delivery provides unique therapeutic advantages when compared to systemic chemotherapy. Moreover, intraoral drug delivery systems are self-administrable and can be removed when needed, increasing patient compliance. This article covers important aspects and advances related to the design, development, and efficacy of polymeric systems for intraoral site-specific drug delivery. © 2017 Wiley Periodicals, Inc.

Abstract
Nebivolol (NB)-loaded solid lipid nanoparticles (SLNs) were prepared and modified with chitosan oligosaccharide lactate (COL) and polyethylene glycol (PEG) stearate for improvement of its oral bioavailability. Compritol, poloxamer and lecithin were used for the preparation of SLNs by homogenisation method. After in vitro characterisation effect of lipase, pepsin, or pancreatin on degradation and release rate were investigated. Cytotoxicity and permeation were studied on Caco-2 cells. As COL concentration increased in SLNs, size and zeta potential increased. PEG concentration was reversely proportional to particle size with no change in zeta potential. Encapsulation efficiencies (EEs) were determined as 84-98%. DSC confirmed solubilisation of NB in lipid matrix. A sustained release with no burst effect was determined. The presence of enzymes affected the release. SLNs did not reveal cytotoxicity and highest permeability was obtained with PEG modification. PEG-modified SLNs could be offered as a promising strategy for oral delivery of NB.

Abstract
Liposomes constitute one of the most popular nanocarriers for improving the delivery and efficacy of agents in cancer patients. The purpose of this study was to design and evaluate immunoliposome co-delivery of bufalin and anti-CD40 to induce synergetic therapeutic efficacy while eliminating systemic side effects. Bufalin liposomes (BFL) conjugated with anti-CD40 antibody (anti-CD40-BFL) showed enhanced cytotoxicity compared with bufalin alone. In a mouse B16 melanoma model, intravenous injection of anti-CD40-BFL achieved smaller tumor volume than did treatment with BFL (average: 117 mm3 versus 270 mm3, respectively); the enhanced therapeutic efficacy through a caspase-dependent pathway induced apoptosis, which was confirmed using terminal deoxynucleotidyl transferase-mediated dUTP-Fluorescein nick end labeling and Western blot assay. Meanwhile, anti-CD40-BFL elicited unapparent body-weight changes and a significant reduction in serum levels of tumor necrosis factor-α, interleukin-1β, interleukin-6, interferon-γ, and hepatic enzyme alanine transaminase, suggesting minimized systemic side effects. This may be attributed to the mechanism by which liposomes are retained within the tumor site for an extended period of time, which is supported by the following biodistribution and flow cytometric analyses. Taken together, the results demonstrated a highly promising strategy for liposomal vehicle transport of anti-CD40 plus bufalin that can be used to enhance antitumor effects via synergetic systemic immunity while blocking systemic toxicity.

Abstract
The fluorescence properties of the new potent antitumoral methyl 3-amino-6-(benzo[d]thiazol-2-ylamino)thieno[3,2-b]pyridine-2-carboxylate in solution and when encapsulated in several different nanoliposome formulations were investigated. The compound exhibits very reasonable fluorescence quantum yields and a solvent sensitive emission in several polar and non-polar media, despite not being fluorescent in protic solvents. Fluorescence anisotropy measurements of the compound incorporated into liposomes revealed that this thienopyridine derivative can be carried in the hydrophobic region of the lipid membrane. Liposome formulations including this antitumor compound are nanometric in size, with a diameter lower than 130 nm and generally low polydispersity, and are promising for future drug delivery developments. The interaction of the compound with bovine serum albumin (BSA) and the multidrug resistance protein MDR1 was monitored by FRET, the compound acting as an energy acceptor. It was observed that the drug had a lower interaction with the MDR1 protein than with the native form of BSA, which is an important result regarding applications of this antitumoral drug.

Abstract
Hyaluronidase is an enzyme that catalyzes breakdown of hyaluronic acid. This property is utilized for hypodermoclysis and for treating extravasation injury. Hyaluronidase is further studied for possible application as an adjuvant for increasing the efficacy of other drugs. Development of suitable carrier system for hyaluronidase would help in coadministration of other drugs. In the present study, the hyaluronidase was encapsulated in liposomes. The effect of variables, namely, phosphatidylcholine (PC), cholesterol, temperature during film formation (T1), and speed of rotation of the flask during film formation (SPR) on percentage of protein encapsulation, was first analyzed using factorial design. The study showed that level of phosphatidylcholine had the maximum effect on the outcome. The effect of interaction of PC and SPR required for preparation of nanoliposomes was identified by central composite design (CCD). The dependent variables were percentage protein encapsulation, particle size, and zeta potential. The study showed that ideal conditions for production of hyaluronidase loaded nanoliposomes are PC—140 mg and cholesterol 1/5th of PC when the SPR is 150 rpm and T1 is 50°C.

Abstract
The determination of the nanocarrier fate in preclinical models is required before any translation from laboratory to clinical trials. Modern fluorescent imaging techniques have gained considerable advances becoming a powerful technology for non-invasive visualization in living subjects. Among them, Forster (fluorescence) resonance energy transfer (FRET) is a particular fluorescence imaging which involves energy transfer between 2 fluorophores in a distance-dependent manner. Considering this feature, the encapsulation of an acceptor/donor pair in lipid nanoparticles (LNEs: lipid nanoemulsions, LNCs: lipid nanocapsules) allowed the carrier integrity to be tracked. Accordingly, we used this FRET technique to evaluate the behavior of LNEs, conventional LNCs and newly designed stealth LNCs. After the development through a one-step (OS) PEGylation process of these stealth LNCs (OS LNCs), in vitro guest exchange dynamics and release kinetics were evaluated for both LNC formulations. We thereafter assessed in vivo biodistribution of all types of lipid nanoparticles. Results showed enhanced stability of encapsulation in OS LNCs in comparison to conventional LNCs. Additionally, the presence of the long PEG chains on the lipid nanoparticle surface altered the biodistribution pattern. Despite different release kinetic profiles, OS LNCs and LNEs showed extended blood circulation time associated with a good structure stability over several hours after intravenous injection.

Abstract
In this study, we developed the cancer treatment through the combination of chemotherapy and thermotherapy using doxorubicin-loaded magnetic liposomes. The citric acid-coated magnetic nanoparticles (CAMNP, ca. 10 nm) and doxorubicin were encapsulated into the liposome (HSPC/DSPE/cholesterol = 12.5:1:8.25) by rotary evaporation and ultrasonication process. The resultant magnetic liposomes (ca. 90 to 130 nm) were subject to characterization including transmission electron microscopy (TEM), dynamic light scattering (DLS), X-ray diffraction (XRD), zeta potential, Fourier transform infrared (FTIR) spectrophotometer, and fluorescence microscope. In vitro cytotoxicity of the drug carrier platform was investigated through 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay using L-929 cells, as the mammalian cell model. In vitro cytotoxicity and hyperthermia (inductive heating) studies were evaluated against colorectal cancer (CT-26 cells) with high-frequency magnetic field (HFMF) exposure. MTT assay revealed that these drug carriers exhibited no cytotoxicity against L-929 cells, suggesting excellent biocompatibility. When the magnetic liposomes with 1 μM doxorubicin was used to treat CT-26 cells in combination with HFMF exposure, approximately 56% cells were killed and found to be more effective than either hyperthermia or chemotherapy treatment individually. Therefore, these results show that the synergistic effects between chemotherapy (drug-controlled release) and hyperthermia increase the capability to kill cancer cells.

Abstract
Nanotechnology is an innovative approach that has potential applications in nutraceutical research. Phytochemicals have promising potential for maintaining and promoting health, as well as preventing and potentially treating some diseases. However, the generally low solubility, stability, bioavailability and target specificity, together with the side effects seen when used at high levels, have limited their application. Indeed, nanoparticles can increase solubility and stability of phytochemicals, enhance their absorption, protect them from premature degradation in the body and prolong their circulation time. Moreover, these nanoparticles exhibit high differential uptake efficiency in the target cells (or tissue) over normal cells (or tissue) through preventing them from prematurely interacting with the biological environment, enhanced permeation and retention effect in disease tissues and improving their cellular uptake, resulting in decreased toxicity, In this review, we outline the commonly used biocompatible and biodegradable nanoparticles including liposomes, emulsions, solid lipid nanoparticles, nanostructured lipid carriers, micelles and poly(lactic-co-glycolic acid) nanoparticles. We then summarize studies that have used these nanoparticles as carriers for epigallocatechin gallate, quercetin, resveratrol and curcumin administration to enhance their aqueous solubility, stability, bioavailability, target specificity and bioactivities.

Abstract
Nanomedicine is a growing research field dealing with the creation and manipulation of materials at a nanometer scale for the better treatment, diagnosis and imaging of diseases. In cancer medicine, the use of nanoparticles as drug delivery systems has advanced the bioavailability, in vivo stability, intestinal absorption, solubility, sustained and targeted delivery, and therapeutic effectiveness of several anticancer agents. The expansion of novel nanoparticles for drug delivery is an exciting and challenging research filed, in particular for the delivery of emerging cancer therapies, including small interference RNA (siRNA) and microRNA (miRNAs)-based molecules. In this review, we focus on the currently available drug delivery systems for anticancer agents. In addition, we will discuss the promising use of nanoparticles for novel cancer treatment strategies.
