Abstract
PEGylation is currently used for the synthesis of stealth liposomes and to enhance the pharmacokinetic and biopharmaceutical properties of payloads. PEGylated dendron phospholipids can decrease the detachment of polyethylene glycol (PEG) from the liposomal surface owing to an increased hydrophobic anchoring effect on the phospholipid bilayer of liposomes and thus generating super stealth liposomes that are suitable for the systemic delivery of anticancer drugs. Herein, doxorubicin hydrochloride-loaded super stealth liposomes were studied for the treatment of breast cancer lung metastasis in an animal model. The results demonstrated that the super stealth liposomes had suitable physicochemical properties for in vivo administration and could significantly increase the efficacy of doxorubicin in breast cancer lung metastasis tumor-bearing mice compared to the free drug. The super stealth liposomes also increased doxorubicin accumulation inside the tumor tissue. The permanence of PEG on the surface of the super stealth liposomes favored the formation of a depot of therapeutic nanocarriers inside the tumor tissue by improving their permanence after stopping treatment. The doxorubicin-loaded super stealth liposomes increased the survival of the mouse tumor model. These promising results demonstrate that the doxorubicin-loaded super stealth liposomes could be an effective nanomedicine to treat metastatic breast cancer.

Abstract
In this study, we designed and developed a novel asialoglycoprotein receptor (ASGPR)-targeted PEGylated paclitaxel (PTX) nanoliposome for hepatocellular carcinoma (HCC). N-acetylgalactosamine with α configuration (Tn) was synthesized and used as the active targeting ligand. Notably, Tn modified nanoliposomes loaded with PTX (Tn-Lipo-PTX) showed a narrow distribution (PDI = 0.18-0.20) with 74 ± 0.36 nm of average sizes. Tn-Lipo-PTX has a high encapsulation efficiency of more than 93.0% and 13% of drug loading (DL). Compared with no targeted Con-Lipo-PTX, Tn-Lipo-PTX showed lower and sustained release characteristic in PBS in vitro. Tn targeting ASGPR was confirmed by HepG-2 cells uptake experiment by fluorescence microscopy analysis. Tn-Lipo-PTX accumulated in HepG-2 cells and this process was inhibited by adding Tn ligand, supporting receptor-mediated endocytosis mechanism. MTT assays was implemented in four cell lines. Tn-Lipo-PTX exhibited superior inhibition against ASGPR on over-expressing HepG-2 (IC50 = 1.93 nM). The cell cycle experiments showed that Tn-Lipo-PTX could efficiently increase the percentage of cells arrest in the G2/M phase. Through western blotting analysis, the β-tubulin and cyclin B1 expression in the Tn-Lipo-PTX group were significantly higher compared with other groups and the CDK1 was down-regulated compared with PTX group, which indicated that targeting liposome delivery system could not only change periodic proteins expression, but also improve the killing effect of PTX on hepatocarcinoma cell. Tn-installed PEGylated nanoliposomes have a great potential for targeted cancer chemotherapy.

MT1-MMP-Activated Liposomes to Improve Tumor Blood Perfusion and Drug Delivery for Enhanced Pancreatic Cancer Therapy. ADVANCED SCIENCE (WEINHEIM, BADEN-WURTTEMBERG, GERMANY) 2020; 7:1902746.

Abstract
Promoting tumor angiogenesis effectively and specifically to resolve tumor-associated hypoperfusion holds promise for improving pancreatic cancer therapy. Herein, a doxorubicin (DOX) loaded smart liposome, MC-T-DOX, is constructed, that carries appropriately low-density cilengitide, an αvβ3 integrin-specific Arg-Gly-Asp (RGD)-mimetic cyclic peptide, via a membrane type 1-matrix metalloproteinase (MT1-MMP) cleavable peptide. After being administered systemically in a hypoperfused pancreatic cancer mouse model at a low dose of cilengitide, the proangiogenic activity of MC-T-DOX is specifically "turned on" in tumor vessels through cleavage by MT1-MMP on tumor endothelial cells to release cilengitide. This locally released cilengitide increases tumor blood perfusion, thereby improving the accumulation and distribution of MC-T-DOX in the tumor site. The loaded-DOX then displays enhanced penetration and increased cellular uptake upon heat-triggered release from MC-T-DOX in the tumor interstitium, contributing to the improved tumor therapy efficacy. Therefore, the strategy of combining the modulation of tumor vascular promotion with smart nanodrug delivery represents a promising approach to improving drug delivery and therapeutic efficacy in a wide range of hypoperfused tumors.

Abstract
In this study, we evaluated and screened the effects of the molecular weight (MW) and molar ratio of poly(2-ethyl-2-oxazoline)-cholesteryl methyl carbonate (PEtOz-CHMC) on the pH sensitivity, stability, and antitumor efficacy of liposomes. The pH sensitivity of PEtOz-CHMC with different MWs and molar ratios was screened by drug release and cytotoxicity experiments at different pH levels. Results indicated that the liposomes coated with PEtOz1k-CHMC (7% molar ratio) and PEtOz2k-CHMC (5% molar ratio) exhibited the desirable pH responsiveness. When the MW of PEtOz was relatively low, 7% of the modified ratio obtained the strongest stability, but the turbidity of the liposomes did not obviously change when the molar ratio of PEtOz-CHMC was further increased. A375 cells were used as models to investigate the cellular uptake and intracellular localization of coumarin-6-loaded liposomes (C6-L), PEGylated liposomes (PEG-C6-L), and PEtOzylated liposomes. PEtOz1k-C6-L and PEtOz2k-C6-L presented remarkably stronger fluorescence intensity at low pH than at pH 7.4, whereas C6-L and PEG-C6-L did not achieve any obvious diversity at different pH conditions. Compared with C6-L and PEG-C6-L, PEtOz-C6-L showed efficient intracellular trafficking, including endosomal/lysosomal escape and cytoplasmic release. Pharmacokinetic experiments demonstrated that half-lives of PEG2k-C6-L, PEtOz2k-C6-L, and PEtOz1k-C6-L were 11.89-, 7.00-, and 5.29-fold times higher than those of C6-L, respectively. Among the liposomes, the DOX·HCl-loaded liposomes coated with PEtOz2k-CHMC demonstrated the strongest antitumor efficacy against B16 tumor xenograft models in vivo. These findings provide the feasibility of using PEtOz-CHMC with optimal pH sensitivity and long circulation to extend the application of liposomes to efficient anticancer drug delivery.

Abstract
Purpose Boron neutron capture therapy (BNCT) is an emerging binary radiotherapy, which is limited for application due to the challenge of targeted delivery into tumor nowadays. Here, we propose the use of iRGD-modified polymeric nanoparticles for active targeted delivery of boron and doxorubicin (DOX) in BNCT. Methods 10B-enriched BSH was covalently grafted to PEG-PCCL to prepare 10B-polymer, then surface-modified with iRGD. And, DOX was physically incorporated into polymers afterwards. Characterization of prepared polymers and in vitro release profile of DOX from polymers were determined by several methods. Cellular uptake of DOX was observed by confocal microscope. Accumulation of boron in cells and tissues was analyzed by ICP-MS. Biodistribution of DOX was studied by ex vivo fluorescence imaging and quantitative measurement. Tumor vascular normalization of Endostar for promoting delivery efficiency of boron on refractory B16F10 tumor was also studied. Results The polymers were monodisperse and spheroidal in water with an average diameter of 24.97 nm, which were relatively stable at physiological pH and showed a sustained release of DOX, especially at endolysosomal pH. Enhanced cellular delivery of DOX was found in iRGD-modified polymer group. Cellular boron uptake of iRGD-modified polymers in A549 cells was remarkably raised fivefold (209.83 ng 10B/106 cells) compared with BSH. The polymers represented prolonged blood circulation, enhanced tumor accumulation of 10B against BSH, and favorable tumor:normal tissue boron concentration ratios (tumor:blood = 14.11, tumor:muscle = 19.49) in A549 tumor-bearing mice 24 hrs after injection. Both fluorescence imaging and quantitative measurement showed the highest tumor accumulation of DOX at 24 hrs after injecting of iRGD-modified polymers. Improvement of vascular integrity and reduction of vascular mimicries were found after Endostar injection, and raised tumor accumulation of boron as well. Conclusion The developed nanoparticle is an inspiring candidate for the safe clinical application for BNCT.

Abstract
Desmoplastic tumors are normally resistant to nanoparticle-based chemotherapy due to dense stroma and limited particle permeability inside the tumor. Herein, we reported that hydralazine (HDZ)-an antihypertension vasodilator-would dramatically promote nanoparticle penetration in advanced desmoplastic tumors. First, a HDZ-liposome system was developed for tumor-selective delivery of HDZ. After three injections of HDZ-liposomes at a dose of 15 mg/kg, the tumor stroma was remarkably reduced, along with ameliorated tumor hypoxia in murine models of desmoplastic melanoma (BPD6). Furthermore, HDZ-liposome treatment altered the immunosuppressive tumor microenvironment, which provided opportunities for applying this therapeutic system to aid immunotherapy in desmoplastic tumors. Using DiD-loaded liposome as a model nanoparticle, we showed that HDZ-liposome treatment significantly increased nanoparticle accumulation and penetration inside desmoplastic tumors. As a result, one single injection of doxorubicin-liposomes at a dose of 5 mg/kg resulted in strong tumor inhibition effect after HDZ-liposome pretreatment in the advanced desmoplastic melanoma with sizes over 400 mm3. Because HDZ is a widely used antihypertension drug, the findings here should be readily translatable for clinical benefits.

Abstract
Nanoparticles have shown great promise in improving cancer treatment efficacy while reducing toxicity and treatment side effects. Predicting the treatment outcome for nanoparticle systems by measuring nanoparticle biodistribution has been challenging due to the commonly unmatched, heterogeneous distribution of nanoparticles relative to free drug distribution. We here present a proof-of-concept study that uses mathematical modeling together with experimentation to address this challenge. Individual mice with 4T1 breast cancer were treated with either nanoparticle-delivered or free doxorubicin, with results demonstrating improved cancer kill efficacy of doxorubicin loaded nanoparticles in comparison to free doxorubicin. We then developed a mathematical theory to render model predictions from measured nanoparticle biodistribution, as determined using graphite furnace atomic absorption. Model analysis finds that treatment efficacy increased exponentially with increased nanoparticle accumulation within the tumor, emphasizing the significance of developing new ways to optimize the delivery efficiency of nanoparticles to the tumor microenvironment.

Abstract
Zwitterionic poly(carboxybetaine) (PCB), poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) and non-ionic poly(ethylene glycol) (PEG), which have similar degrees of polymerization, were grafted to branched polyethyleneimine (PEI) to generate PCB-grafted PEI (PEI-PCB), PMPC-grafted PEI (PEI-PMPC) and PEG-grafted PEI (PEI-PEG) copolymers, respectively. These grafted PEI copolymers with almost the same grafting number were coated on the surface of 110 nm bovine serum albumin-poly(N-3-acrylamidophenylboronic acid) (BSA-PAPBA) nanoparticles to make a comparison of the surface decoration effect on the biodistribution of nanoparticles. Compared to the nanoparticles without surface decoration, surface decoration with the copolymers significantly prolonged the circulation time of BSA-PAPBA nanoparticles, leading to remarkable enhancement of tumor uptake of the nanoparticles. The drug accumulation at the tumor site reached more than 10% injected dose per gram of tumor. Among them, the PEI-PMPC-decorated nanoparticles exhibited the best performance in tumor accumulation and anticancer ability. Thus, these surface-decorated nanoparticles may serve as a strong candidate for high tumor accumulation of drug delivery systems.

Kim JH, Shin BC, Park WS, Lee J, Kuh HJ. Antifibrotic effects of pentoxifylline improve the efficacy of gemcitabine in human pancreatic tumor xenografts. Cancer Sci 2017; 108:2470-2477. [PMID: 28940685 PMCID: PMC5715266 DOI: 10.1111/cas.13405] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2017] [Revised: 09/12/2017] [Accepted: 09/13/2017] [Indexed: 02/06/2023] Open
Abstract
We investigated the combinatorial effects of pentoxifylline (PTX) on the efficacy of gemcitabine (GEM) in a human pancreatic tumor xenograft model. PTX significantly improved the efficacy of GEM, as shown by a 50% reduction in tumor growth rate at 4 weeks of treatment compared with that in animals given GEM alone. The fluorescent drug doxorubicin (DOX) was used to test whether drug delivery was improved by PTX, contributing to the improved efficacy of GEM. PTX given for 2 weeks prior to giving DOX improved drug distribution by 1.8‐ to 2.2‐fold with no changes in vessel density, suggesting that improvement in drug delivery was not related to the vascular mechanism. Instead, collagen I content in tumor stroma was significantly reduced, as was the expression of alpha‐smooth muscle actin of cancer‐associated fibroblasts and connective tissue growth factor (CTGF) by PTX pretreatment. Overall, our data demonstrated that increased efficacy of GEM by PTX was associated with improved drug delivery to tumor tissue, which may be attributed to decreased expression of CTGF and subsequent reduction in the stromal collagen matrix in the pancreatic ductal adenocarcinoma tumor. These results support the usefulness of PTX in combination with chemotherapy for targeting drug delivery barriers associated with the stromal matrix, which should be further evaluated for clinical development.

Abstract
Abstract
In this study, 1 wt% lecithin (–), chitosan (+), and λ-carrageenan (–) were prepared to manufacture multiple-layered liposomes with optimal formulations developed in a previous study by using layer-by-layer electrostatic deposition. We observed their particle size, ζ-potential, sedimentation behavior, and microstructure for 6 weeks. Multiple-layered liposomes were quenched with calcein to evaluate stability in terms of factors such as encapsulation efficiency and released amount of calcein. The particle size of multi-layered liposomes increased with storage periods and the ζ-potential of multiple-layered liposomes gained a neutral charge. Interestingly, negatively charged layered liposomes were smaller than positively charged layered liposomes and showed a lower polydispersity index. Moreover, the ζ-potential did not apparently change compared to positively charged layered liposomes. For the calcein release study, multiple-layered liposomes significantly sustained quenched calcein more than that observed using non-layered liposomes. This study showed that it was possible to increase the thickness of the liposome surface and to manipulate its charge using chitosan and λ-carrageenan through electrostatic deposition. Results showed that manufacturing negatively charged multiple-layer (over 4-layer) liposomes with charged biopolymer improved the physicochemical stability of liposomes.

Abstract
Nanocarriers, due to their unique features, are of increased interest among researchers working with pharmaceutical formulations. Polymeric nanoparticles and nanocapsules, involving non-toxic biodegradable polymers, liposomes, solid lipid nanoparticles, and inorganic-organic nanomaterials, are among the most used carriers for drugs for a broad spectrum of targeted diseases. In fact, oral, injectable, transdermal-dermal and ocular formulations mainly consist of the aforementioned nanomaterials demonstrating promising characteristics such as long circulation, specific targeting, high drug loading capacity, enhanced intracellular penetration, and so on. Over the last decade, huge advances in the development of novel, safer and less toxic nanocarriers with amended properties have been made. In addition, multifunctional nanocarriers combining chemical substances, vitamins and peptides via coupling chemistry, inorganic particles coated by biocompatible materials seem to play a key role considering that functionalization can enhance characteristics such as biocompatibility, targetability, environmental friendliness, and intracellular penetration while also have limited side effects. This review aims to summarize the "state of the art" of drug delivery carriers in nanosize, paying attention to their surface functionalization with ligands and other small or polymeric compounds so as to upgrade active and passive targeting, different release patterns as well as cell targeting and stimuli responsibility. Lastly, future aspects and potential uses of nanoparticulated drug systems are outlined.

Abstract
A novel delivery concept based on the integration of liposomes in hydrogel for the controlled release of liposomes was developed. As an in situ forming hydrogel, chitosan-glycerophosphate was used and gelation time at different temperatures was studied. Liposomes (DSPC/chol/DOPE) were labelled with (99m)Tc-hexamethylpropyleneamineoxime ((99m)Tc-HMPAO). (99m)Tc-HMPAO solution, hydrogel/(99m)Tc-HMPAO, (99m)Tc-HMPAO liposomes and hydrogel/(99m)Tc-HMPAO liposomes were injected into mouse peritoneum. The percentages of radioactive injected dose per gram of tissue (%ID/g) and %ID of peritoneum lavage were obtained. Results showed that free label left the peritoneal cavity rapidly in both solution and hydrogel forms, such that the activity was 2.5 and 3.8 (%ID) after one hour, respectively. The values for liposomes and liposomal hydrogel were 25.8 and 51.2 (%ID) and decreased to 1.9 and 19.2 after 24 h, respectively. The blood profile of liposomal hydrogel showed a two-phase profile including a descending trend in early hours regarding gel formation followed by an ascending trend due to gel disappearance by time. Free label had high activity in reticuloendothelial system (RES) and the gastrointestinal tract during the early hours and then dropped. In contrast, the accumulation of liposomes increased in RES during 24 h in the range of 1-34.5 and 1.1-35.1 (%ID/g) for plain liposomes and liposomal hydrogel, respectively. Overall, incorporation of liposomes in hydrogel could be a useful strategy to prolong the release of liposomes.

Abstract
Span 80 (sorbitan monooleate) vesicles behaved differently from conventional phospholipid vesicles (liposomes) because the former had a more fluid interface. After doxorubicin hydrochloride (DOX) was encapsulated into the Span 80 vesicle (loading efficiency: 63 %), DOX-loaded Span 80 vesicles (DVs) were thereafter added to Colon 26 cells. It was suggested, from the flow cytometric analysis and confocal laser microscopic observation, that DVs directly deliver DOX into the cytoplasm of Colon 26 cells. DVs showed the different delivery manner from the DOX-loaded liposomes (DLs). It is considered that the difference of delivery manner between DVs and DLs resulted in the difference of cytotoxicity (IC50); i.e. IC50 values for DVs and DLs were 5 and > 30 μM, respectively. The results obtained herein would give the fundamental findings which can contribute to the improvement of formulation of conventional liposome-based carrier and its cytotoxicity.

Abstract
Cancer treatment by chemotherapy is typically accompanied by deleterious side effects, attributed to the toxic action of chemotherapeutics on proliferating cells from nontumor tissues. The cell surface proteoglycan CD44 has been recognized as a cancer stem cell marker. The present study has examined CD44 targeting as a way to selectively deliver therapeutic agents encapsulated inside colloidal delivery systems. CD44/chondroitin sulfate proteoglycan binds to a triple-helical sequence derived from type IV collagen, α1(IV)1263–1277. We have assembled a peptide-amphiphile (PA) in which α1(IV)1263–1277 was sandwiched between 4 repeats of Gly-Pro-4-hydroxyproline and conjugated to palmitic acid. The PA was incorporated into liposomes composed of DSPG, DSPC, cholesterol, and DSPE-PEG-2000 (1 : 4 : 5 : 0.5). Doxorubicin-(DOX-)loaded liposomes with and without 10% α1(IV)1263–1277 PA were found to exhibit similar stability profiles. Incubation of DOX-loaded targeted liposomes with metastatic melanoma M14#5 and M15#11 cells and BJ fibroblasts resulted in IC50 values of 9.8, 9.3, and >100 μM, respectively. Nontargeted liposomes were considerably less efficacious for M14#5 cells. In the CD44+ B16F10 mouse melanoma model, CD44-targeted liposomes reduced the tumor size to 60% of that of the untreated control, whereas nontargeted liposomes were ineffective. These results suggest that PA targeted liposomes may represent a new class of nanotechnology-based drug delivery systems.

Abstract
Background N-lactosyl-dioleoylphosphatidylethanolamine (Lac-DOPE) was synthesized and evaluated as a liver-specific targeting ligand via asialoglycoprotein receptors for liposomal delivery of doxorubicin. Methods Lactosylated liposomes encapsulating calcein (Lac-L-calcein) or doxorubicin (Lac-L-DOX) composed of egg phosphatidylcholine, cholesterol, monomethoxy polyethylene glycol 2000-distearoyl phosphatidylethanolamine, and Lac-DOPE at 50:35:5:10 (mol/mol) were prepared by polycarbonate membrane extrusion and evaluated in human hepatocellular carcinoma HepG2 cells. Cellular uptake of Lac-L-calcein was monitored by confocal microscopy and by flow cytometry. The cytotoxicity of Lac-L-DOX was evaluated by MTT assay. The pharmacokinetic properties of Lac-L-DOX were studied in normal mice, and its biodistribution and antitumor activity were studied in nude mice with HepG2 xenografts. Results The size of Lac-L-DOX was less than 100 nm and the liposomes demonstrated excellent colloidal stability. In vitro uptake of Lac-L-calcein by HepG2 cells was four times greater than that of non-targeted L-calcein. In the presence of 20 mM lactose, the uptake of Lac-L-calcein was inhibited, suggesting that asialoglycoprotein receptors mediated the observed cellular uptake. Lac-L-DOX exhibited enhanced in vivo cytotoxicity compared with the nontargeted liposomal doxorubicin (L-DOX), and its pharmacokinetic parameters indicate that Lac-L-DOX has a long blood circulation time (t1/2 8.73 hours). Tissue distribution and therapeutic efficacy studies in nude mice bearing HepG2 xenografts show that Lac-L-DOX had significantly stronger tumor inhibitory activity compared with L-DOX and free doxorubicin, along with a higher accumulation of drug within the tumor site and greater cellular uptake by tumor cells. Conclusion These data suggest that lactosylated liposomes are promising drug delivery vehicles for hepatocellular carcinoma.

Abstract
Background This study was performed to develop a functional poly(D,L-lactide-co-glycolide)- poly(ethylene glycol) (PLGA-PEG)-bearing amino-active end group for peptide conjugation. Methods and results PLGA was preactivated following by copolymerization with PEG diamine. The resulting amphiphilic PLGA-PEG copolymer bearing 97.0% of amino end groups had a critical micelle concentration of 3.0 × 10−8 mol/L, and the half-effective inhibition concentration (IC50) of the prepared PLGA-PEG nanoparticles was >100 mg/mL, which was much higher than that of PLGA nanoparticles (1.02 ± 0.37 mg/mL). The amphiphilic properties of PLGA-PEG spontaneously formed a core-shell conformation in the aqueous environment, and this special feature provided the amino group on the PEG chain scattered on the surface of PLGA-PEG nanoparticles for efficient peptide conjugation. The peptide-conjugated PLGA-PEG nanoparticles showed three-fold higher uptake than peptide-free PLGA-PEG nanoparticles in a SKOV3 cell line with high expression of epidermal growth factor receptor. Both peptide-conjugated and peptide-free PLGA-PEG nanoparticles were used as nanocarriers for delivery of doxorubicin. Although the rate of release of doxorubicin from both nanoparticles was similar, drug release at pH 4.0 (500 U lipase) was faster than at pH 7.4. The IC50 of doxorubicin-loaded peptide-conjugated PLGA-PEG nanoparticles in SKOV3 cells (0.05 ± 0.03 μg/mL) was much lower (by 62.4-fold) than that of peptide-free PLGA-PEG nanoparticles (3.12 ± 1.44 μg/mL). Conclusion This in vivo biodistribution study in SKOV3 tumor-bearing mice was further promising in that accumulation of doxorubicin in tumor tissue was in the order of peptide-conjugated PLGA-PEG nanoparticles > peptide-free PLGA-PEG nanoparticles > doxorubicin solution.

Abstract
Ultrasound-sensitive (sonosensitive) liposomes for tumor targeting have been studied in order to increase the antitumor efficacy of drugs and decrease the associated severe side effects. Liposomal contrast agents having Gd(III) are known as a nano-contrast agent system for the efficient and selective delivery of contrast agents into pathological sites. The objective of this study was to prepare Gd(III)-DOTA-modified sonosensitive liposomes (GdSL), which could deliver a model drug, doxorubicin (DOX), to a specific site and, at the same time, be capable of magnetic resonance (MR) imaging. The GdSL was prepared using synthesized Gd(III)-DOTA-1,2-distearoyl-sn-glycero-3-phosphoethanolamine lipid. Sonosensitivity of GdSL to 20-kHz ultrasound induced 33% to 40% of DOX release. The relaxivities (r1) of GdSL were 6.6 to 7.8 mM-1 s-1, which were higher than that of MR-bester®. Intracellular uptake properties of GdSL were evaluated according to the intensity of ultrasound. Intracellular uptake of DOX for ultrasound-triggered GdSL was higher than that for non-ultrasound-triggered GdSL. The results of our study suggest that the paramagnetic and sonosensitive liposomes, GdSL, may provide a versatile platform for molecular imaging and targeted drug delivery.

Abstract
The presence of circulating tumor cells (CTCs) is believed to lead to the formation of secondary tumors via an adhesion cascade involving interaction between adhesion receptors of endothelial cells and ligands on CTCs. Many CTCs express sialylated carbohydrate ligands on their surfaces that adhere to selectin protein found on inflamed endothelial cells. We have investigated the feasibility of using immobilized selectin proteins as a targeting mechanism for CTCs under flow. Herein, targeted liposomal doxorubicin (L-DXR) was functionalized with recombinant human E-selectin (ES) and polyethylene glycol (PEG) to target and kill cancer cells under shear flow, both when immobilized along a microtube device or sheared in a cone-and-plate viscometer in a dilute suspension. Healthy circulating cells such as red blood cells were not targeted by this mechanism and were left to freely circulate, and minimal leukocyte death was observed. Halloysite nanotube (HNT)-coated microtube devices immobilized with nanoscale liposomes significantly enhanced the targeting, capture, and killing of cancer cells. This work demonstrates that E-selectin functionalized L-DXR, sheared in suspension or immobilized onto microtube devices, provides a novel approach to selectively target and deliver chemotherapeutics to CTCs in the bloodstream.

Abstract
The focus on nanotechnology in cancer treatment and diagnosis has intensified due to the serious side effects caused by anticancer agents as a result of their cytotoxic actions on normal cells. This nonspecific action of chemotherapy has awakened a need for formulations capable of definitive targeting with enhanced tumor-killing. Nanooncology, the application of nanobiotechnology to the management of cancer, is currently the most important area of nanomedicine. Currently several nanomaterial-based drug-delivery systems are in vogue and several others are in various stages of development. Tumor-targeted drug-delivery systems are envisioned as magic bullets for cancer therapy and several groups are working globally for development of robust systems.

Abstract
Background Efficient delivery of anticancer chemotherapies such as paclitaxel (PTX) can improve treatment strategy in a variety of tumors such as breast and ovarian cancers. Accordingly, researches on polymeric nanomicelles continue to find suitable delivery systems. However, due to biocompatibility concerns, a few micellar nanoformulations have exquisitely been translated into clinical uses. Here, we report the synthesis of novel water-soluble nanomicelles using bioactive polyurethane (PU) polymer and efficient delivery of PTX in the human breast cancer MCF-7 cells. Results The amphiphilic polyurethane was prepared through formation of urethane bounds between hydroxyl groups in poly (tetramethylene ether) glycol (PTMEG) and dimethylol propionic acid with isocyanate groups in toluene diisocyanate (TDI). The free isocyanate groups were blocked with phenol, while the free carboxyl groups of dimethylol propionic acid were reacted with triethylamine to attain ionic centers in the polymer backbone. These hydrophobic PTMEG blocks displayed self-assembly forming polymeric nanomicelles in water. The PTX loaded PU nanomicelles showed suitable physical stability, negative zeta potential charge (-43) and high loading efficiency (80%) with low level of critical micelle concentration (CMC). In vitro drug release profile showed a faster rate of drug liberation at pH 5.4 as compared to that of pH 7.4, implying involvement of a pH-sensitive mechanism for drug release from the nanomicelles. The kinetic of release exquisitely obeyed the Higuchi model, confirming involvement of diffusion and somewhat erosion at pH 5.4. These nanomicelles significantly inhibited the growth and proliferation of the human breast cancer MCF-7 cells, leading them to apoptosis. The real time RT-PCR analysis confirmed the activation of apoptosis as result of liberation of cytochrome c in the cells treated with the PTX loaded PU nanomicelles. The comet assay analysis showed somewhat DNA fragmentation in the treated cells. Conclusions Based upon these findings, we propose that the bioactive waterborne polyurethane nanomicelles can be used as an effective nanocarrier for delivery of anticancer chemotherapies such as paclitaxel.

Abstract
Hematogenous metastasis, the process of cancer cell migration from a primary to distal location via the bloodstream, typically leads to a poor patient prognosis. Selectin proteins hold promise in delivering drug-containing nanocarriers to circulating tumor cells (CTCs) in the bloodstream, due to their rapid, force-dependent binding kinetics. However, it is challenging to deliver such nanocarriers while avoiding toxic effects on healthy blood cells, as many possess ligands that adhesively interact with selectins. Herein, we describe a nanostructured surface to capture flowing cancer cells, while preventing human neutrophil adhesion. Microtube surfaces with immobilized halloysite nanotubes (HNTs) and E-selectin functionalized liposomal doxorubicin (ESPEG L-DXR) significantly increased the number of breast adenocarcinoma MCF7 cells captured from flow, yet also significantly reduced the number of captured neutrophils. Neutrophils firmly adhered and projected pseudopods on surfaces coated only with liposomes, while neutrophils adherent to HNT-liposome surfaces maintained a round morphology. Perfusion of both MCF7 cells and neutrophils resulted in primarily cancer cell adhesion to the HNT-liposome surface, and induced significant cancer cell death. This work demonstrates that nanostructured surfaces consisting of HNTs and ES-PEG L-DXR can increase CTC recruitment for chemotherapeutic delivery, while also preventing healthy cell adhesion and uptake of therapeutic intended for CTCs.

Abstract
A N-octyl-O-sulfate chitosan (NOSC) anchored liposome system was developed as the carrier for antitumor drug, docetaxel (DTX). The physicochemical and pharmacokinetic properties of NOSC-modified DTX liposomes (NDLs) were evaluated compared with the conventional DTX liposomes (DLs) and commercial dosage form of DTX, Taxotere(®). The results showed that NDLs had DTX-loading rate of 3.41%, entrapment efficiency of 61.73%, narrow distributed particle size of 147.6±1.9nm, and high zata potential of -44.2±3.9mV. The decreased permeability of the liposome bilayer was evaluated by release behavior of calcein (CAL) from the internal phase of NOSC-modified CAL liposomes (NCLs) and enhanced stability of NDLs owed to shielding effect of sulfonic shell from adsorption by BSA. After i.v. administration at the dose of 12mg/kg, a significant increase in the AUC, MRT, and T(1/2β) (P<0.05) was observed in NDLs group compared with DLs and Taxotere(®) group. AUC(0-∞) of NDLs was 6.14 and 1.55 times higher than Taxotere(®) and DLs, respectively, and MRT(0-∞) of NDLs was 5.77 and 1.37 times higher than Taxotere(®) and DLs, respectively. All these results suggested that anchored liposomes could increase the stability of DTX in vitro and in vivo, as compared with conventional liposomes and Taxotere(®). Therefore, NOSC as a polymeric shell to liposomes was effective to enhance the stability of liposomes containing DTX.

Abstract
The feasibility of using a liposome drug delivery system to formulate octylglycerol (OG) as a vaginal microbicide product was explored. A liposome formulation was developed containing 1% OG and phosphatidyl choline in a ratio that demonstrated in vitro activity against Neisseria gonorrhoeae, HSV-1, HSV-2 and HIV-1 while sparing the innate vaginal flora, Lactobacillus. Two conventional gel formulations were prepared for comparison. The OG liposome formulation with the appropriate OG/lipid ratio and dosing level had greater efficacy than either conventional gel formulation and maintained this efficacy for at least 2 months. No toxicity was observed for the liposome formulation in ex vivo testing in a human ectocervical tissue model or in vivo testing in the macaque safety model. Furthermore, minimal toxicity was observed to lactobacilli in vitro or in vivo safety testing. The OG liposome formulation offers a promising microbicide product with efficacy against HSV, HIV and N. gonorrhoeae.

Abstract
A multifunctional mixed micelle was assembled for drug targeting delivery by combining two newly synthesized amphiphilic polymers, which were octreotide-polyethylene glycol-monostearate (OPMS) and N-octyl-N-succinyl-O-carboxymethyl chitosan (OSCC), respectively. The mixed micelle was designed to be characterized with long circulation, somatostatin receptors (SSTR)-mediated endocytosis and pH sensitivity. A series of assembling proportions of OPMS and OSCC was tested to reveal the effect of compositions on the functions. The particle size, zeta potential, drug loading and critical micelle concentration were examined. The dialysis test indicated a pH-triggering release behavior of the doxorubicin-loaded mixed micelle (DLMM), and faster release in acidic media (pH 4.0-6.0) in response to the protonation of carboxyl group. In addition, the PEG segments could efficiently protect the mixed micelle from plasma protein adsorption in vitro, and the DLMM composed of 20% OPMS and 80% OSCC provided the longest residence time after intravenous injection in rats in vivo. Due to SSTR mediated endocytosis, the significantly higher uptake of DLMM was observed in the tumor cells (SMMC-7721), compared with that in the normal cells (CHO) without SSTR expression. All the results suggested that the mixed micelle with multifunctional characteristics could be used as an effective approach for tumor treatment.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a novel anticancer agent for non-small cell lung cancer (NSCLC). However, approximately half of NSCLC cell lines are highly resistant to TRAIL. Doxorubicin (DOX) can sensitize NSCLC cells to TRAIL-induced apoptosis, indicating the possibility of combination therapy. Unfortunately, the therapeutic effect of a DOX and TRAIL combination is limited by multiple factors including the short serum half-life of TRAIL, poor compliance and application difficulty in the clinic, chronic DOX-induced cardiac toxicity, and the multidrug resistance (MDR) property of NSCLC cells. To solve such problems, we developed the combination of TRAIL liposomes (TRAIL-LP) and DOX liposomes (DOX-LP). An in vitro cytotoxicity study indicated that DOX-LP sensitized the NSCLC cell line A-549 to TRAIL-LP-induced apoptosis. Furthermore, this combination therapy of TRAIL-LP and DOX-LP displayed a stronger antitumor effect on NSCLC in xenografted mice when compared with free drugs or liposomal drugs alone. Therefore, the TRAIL-LP and DOX-LP combination therapy has excellent potential to become a new therapeutic approach for patients with advanced NSCLC.

Abstract
Arginine-glycine-aspartate (RGD) has been shown to possess a strong affinity for the integrins overexpressed in tumor cells, especially during tumor invasion, angiogenesis and metasis. Based on work from others, a novel tetrapeptide, arginine-glycine-aspartate-phenylanaline (RGDF), has been designed and studied as a homing device to direct liposomal doxorubicin (DOX) to tumor cells in this work. In order to incorporate RGDF into liposomal DOX preparations, RGDF was conjugated with three different fatty alcohols to achieve RGDF-fatty alcohol conjugates. Glycine-glycine-aspartate-phenylanaline (GGDF)-lauryl alcohol conjugate was synthesized as a negative control. RGDF-fatty alcohol conjugates (RGDFO(CH(2))(n)CH(3)) and GGDF-lauryl alcohol conjugate (L-GGDFC12-DOX) incorporated liposomal preparations were obtained by first preparing liposomes using the film dispersion method followed by loading DOX using a transmembrane pH gradient method. Because of their amphipathic nature, RGDF- or GGDF-fatty alcohol conjugates are expected to be readily incorporated into liposomes with their fatty alkanyl chains being intercalated between fatty acyl chains of liposomal bilayers and the hydrophilic peptide moiety (RGDF or GGDF) being anchored on the surface of liposomes. The particle size and zeta potential of liposomal DOX preparations containing RGDF-fatty alcohol conjugate (L-RGDF-DOXs) or L-GGDFC12-DOX were measured, and their morphology was studied using transmission electron microscopy. In vitro DOX release profile from RGDF incorporated liposomal DOX was measured. The antitumor activities of RGDF incorporated liposomal DOX preparations were evaluated in ICR mice inoculated with sarcoma S(180), which is known to express α(v)β(3) integrin. Both conventional liposomal DOX preparation (L-DOX) without RGDFO(CH(2))(n)CH(3) and L-GGDFC12-DOX were used as negative controls. Our results showed improved tumor growth inhibition with L-RGDF-DOXs over doxorubicin hydrochloride solution, L-DOX and L-GGDFC12-DOX. Pathological examination of tumor biopsy demonstrated that L-RGDF-DOXs induced enhanced tumor cell death in comparison to negative controls. Pharmacokinetic studies showed that the concentrations of DOX found in tumor sites were increased by 1.7-4.5-fold when liposomal DOX preparation containing RGDF-lauryl alcohol conjugate (L-RGDFC12-DOX) was administered in comparison to when L-GGDFC12-DOX or doxorubicin hydrochloride solution was administered. The concentrations of DOX found in the heart, which is the main site of toxic effects of DOX, were significantly reduced when L-RGDFC12-DOX was administered in comparison to when L-GGDFC12-DOX or doxorubicin hydrochloride solution was administered.

Abstract
Polylysine dendrimers have potential as biodegradable vectors for the delivery of cytotoxic drugs to solid tumours. Here, the cytotoxicity, drug release and tumour targeting properties of Generation 5 PEGylated polylysine dendrimers comprising an outer generation of l-lysine or succinimyldipropyldiamine (SPN) and containing doxorubicin (DOX) linked through an acid labile 4-(hydrazinosulfonyl) benzoic acid (HSBA) linker have been characterised. Less than 10% of the DOX load was released from LYS or SPN dendrimers in pH 7.4 buffer over 3 days. In contrast approximately 100% release was evident at pH 5. The DOX-conjugated dendrimers also retained similar cytotoxic properties to free DOX in in vitro cell culture studies (presumably as a result of in situ liberation of free DOX). The clearance patterns of the DOX conjugated SPN and all-lysine dendrimers were similar to the equivalent non-DOX conjugated systems, however the SPN dendrimers showed reduced metabolic lability and increased uptake into RES organs when compared to the equivalent all-lysine dendrimers. In vivo assessment of the DOX-conjugated, PEGylated polylysine dendrimers (both SPN and LYS constructs) in rats bearing Walker 256 tumours revealed higher uptake into tumour tissue when compared with control tissue such as muscle (~8 fold) and heart (~3 fold). The data suggest that polylysine dendrimers containing DOX conjugated via an acid labile HSBA linker may provide a mechanism to target the delivery of DOX to tumours.

Abstract
Lipid-based drug-delivery systems have evolved from micro- to nano-scale, enhancing the efficacy and therapeutic applications of these delivery systems. Production of lipid-based pharmaceutical nanoparticles is categorized into top-down (fragmentation of particulate material to reduce its average total dimensions) and bottom-up (amalgamation of molecules through chemical interactions creating particles of greater size) production methods. Selection of the appropriate method depends on the physiochemical properties of individual entities within the nanoparticles. The production method also influences the type of nanoparticle formulations being produced. Liposomal formulations and solid-core micelles are the most widely utilized lipid-based nanoparticles, with surface modifications improving their therapeutic outcomes through the production of long-circulating, tissue-targeted and/or pH-sensitive nanoparticles. More recently, solid lipid nanoparticles have been engineered to reduce toxicity toward mammalian cells, while multifunctional lipid-based nanoparticles (i.e., hybrid lipid nanoparticles) have been formulated to simultaneously perform therapeutic and diagnostic functions. This article will discuss novel lipid-based drug-delivery systems, outlining the properties and applications of lipid-based nanoparticles alongside their methods of production. In addition, a comparison between generations of the lipid-based nano-formulations is examined, providing insight into the current directions of lipid-based nanoparticle drug-delivery systems.

Glycyrrhetinic acid-modified poly(ethylene glycol)-b-poly(gamma-benzyl l-glutamate) micelles for liver targeting therapy. Acta Biomater 2010; 6:3927-35. [PMID: 20438873 DOI: 10.1016/j.actbio.2010.04.021] [Citation(s) in RCA: 93] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2010] [Revised: 04/21/2010] [Accepted: 04/27/2010] [Indexed: 11/20/2022]
Abstract
Liver targeted micelles were successfully constructed via self-assembly of glycyrrhetinic acid (GA)-modified poly(ethylene glycol)-b-poly(gamma-benzyl l-glutamate) (GA-PEG-PBLG) block co-polymers, which were fabricated via ring opening polymerization of gamma-benzyl l-glutamate N-carboxyanhydride monomer initiated by GA-modified PEG. The in vivo biodistribution and the in vitro cellular uptake of these micelles were investigated. The results showed that the relative uptake of doxorubicin (DOX)-loaded micelles (DOX/GA-PEG-PBLG) in liver was much higher than in other tissues, and the resulting DOX concentration in liver was about 2.2-fold higher than that from the micelles without modification by GA. Moreover, the cellular uptake study demonstrated that the introduction of GA to the micelles could significantly increase the affinity for human hepatic carcinoma 7703 cells, which induced a 3.7-fold higher endocytosis than unmodified ones. The cytotoxicity of DOX/GA-PEG-PBLG micelles (IC(50) 47 ngml(-1)) was much higher than that of free DOX (IC(50) 90 ngml(-1)). These results indicate that GA-modified micelles have great potential in liver targeting therapy.
