Abstract
The characteristics of the primary tumor blood vessels and the tumor microenvironment drive the enhanced permeability and retention (EPR) effect, which confers an advantage towards enhanced delivery of anti-cancer nanomedicine and has shown beneficial effects in preclinical models. Increased vascular permeability is a landmark feature of the tumor vessels and an important driver of the EPR. The main focus of this review is the endothelial regulation of vascular permeability. We discuss current challenges of targeting vascular permeability towards clinical translation and summarize the structural components and mechanisms of endothelial permeability, the principal mediators and signaling players, the targeted approaches that have been used and their outcomes to date. We also critically discuss the effects of the tumor-infiltrating immune cells, their interplay with the tumor vessels and the impact of immune responses on nanomedicine delivery, the impact of anti-angiogenic and tumor-stroma targeting approaches, and desirable nanoparticle design approaches for greater translational benefit.

Abstract
Drug delivery through the skin improves solubility, bioavailability, and unwanted systemic side effects of the drug. The selection of a suitable carrier is a challenging process. The conventional lipid vesicles have some limitations. They deliver the drug in the stratum corneum and have poor colloidal stability. Here comes the need for ultra-deformable lipid vesicles to provide the drug beyond the stratum corneum. Transethosomes are novel ultra-deformable vesicles that can deliver drugs into deeper tissues. The composition of transethosomes includes phospholipid, ethanol and surfactants. Each ingredient has a pivotal role in the properties of the carrier. This review covers the design, preparation method, characterisation, and characteristics of the novel vesicle. Also, we cover the impact of surfactants on vesicular properties and the skin permeation behaviour of novel vesicles.

Abstract
Oral tadalafil (TD) proved promising in treating pediatric pulmonary arterial hypertension (PAH). However, to ensure higher efficacy and reduce the systemic side effects, targeted delivery to the lungs through nebulization was proposed as an alternative approach. This poorly soluble drug was previously dissolved in nanoemulsions (NEs). However, the formulations could not resist aqueous dilution, which precluded its dilution with saline for nebulization. Thus, the current study aimed to modify the previous systems into dilutable TD-NEs and assess their suitability for a pulmonary application. In this regard, screening of various excipients was conducted to optimize the former systems; different formulations were selected and characterized in terms of physicochemical properties, nebulization performance, stability following sterilization, and biocompatibility. Results showed that the optimal system comprised of Capmul-MCM-EP:Labrafac-lipophile (1:1) (w/w) as oil, Labrasol:Poloxamer-407 (2:1) (w/w) as surfactant mixture (Smix) and water. The optimum formulation P2TD resisted aqueous dilution, exhibited reasonable drug loading (2.45 mg/mL) and globule size (25.04 nm), acceptable pH and viscosity for pulmonary administration, and could be aerosolized using a jet nebulizer. Moreover, P2TD demonstrated stability following sterilization and a favorable safety profile confirmed by both in-vitro and in-vivo toxicity studies. These favorable findings make P2TD promising for the treatment of pediatric PAH.

Abstract
Polymersomes possess the self-assembly vesicular structure similar to liposomes. Although a variety of comparisons between polymersomes and liposomes in the aspects of physical properties, preparation and applications have been elaborated in many studies, few focus on their differences in drug encapsulation, delivery and release in vitro and in vivo. In the present work, we have provided a modified direct hydration method to encapsulate anti-cancer drug paclitaxel (PTX) into PEG-b-PCL constituted polymersomes (PTX@PS). In addition to advantages including narrow particle size distribution, high colloid stability and moderate drug-loading efficiency, we find that the loaded drug aggregate in small clusters and reside through the polymersome membrane, representing a unique core-satellite structure which might facilitate the sustained drug release. Compared with commercial liposomal PTX formulation (Lipusu®), PTX@PS exhibited superb tumor cell killing ability underlain by multiple pro-apoptotic mechanisms. Moreover, endocytic process of PTX@PS significantly inhibits drug transporter P-gp expression which could be largely activated by free drug diffusion. In glioma mice models, it has also confirmed that PTX@PS remarkably eradicate tumors, which renders polymersomes as a promising alternative to liposomes as drug carriers in clinic.

Abstract
Local analgesia is one of the most desirable methods for postoperative pain control, while the existing local anesthetics have a short duration of analgesic effect. Nano-drug carriers have been widely used in various fields and provide an excellent strategy for traditional drugs. Although the existing liposomes for local anesthetics have certain advantages, their instability and complexity of the preparation process still cannot be ignored. Here, we developed novel ropivacaine hydrochloride liposomes with improved stability and sustained release performance by combining ropivacaine hydrochloride with sodium oleate in liposomes via hydrophobic ion-pairing (HIP). The liposomes are easy to prepare, inexpensive, and suitable for mass production. The infrared (IR), particle size, and Zeta potential measurements adequately characterized the complex, which showed a diameter of 81.09 nm and a zeta potential of -83.3 mV. Animal behavioral experiments, including the hot plate test and von Frey fiber test, demonstrated that the liposome system had a prolonged analgesic effect of 2 h versus conventional liposome preparations, consistent with the results of in vitro release experiments. In addition, in vitro cytotoxicity evaluations in RAW264.7 cells and in vivo evaluations revealed the biocompatibility and safety of the ropivacaine-sodium oleate ion-paired liposome (Rop-Ole-Lipo) system as a suitable local anesthetic for local pain management. Our findings provide a new idea for the preparation of local anesthetics.

Abstract
In the present study, different in situ hydrogel formulations of docetaxel (DTX) based on biocompatible polymers such as Hyaluronic Acid (HA), poloxamer-407, chitosan and gellan gum were formulated to increase its therapeutic efficacy and reduce toxicity. DTX was loaded in nanovesicles (20 mg/mL equivalent to commercial strength) and further incorporated into the hydrogel bases to possess a dual rationale of protection against burst release and enhanced solubility of the drug. The optimized hydrogel formulation (NV-TPGS-3-GG-4) showed ideal rheological behavior and in situ characteristics at 37±0.5°C with sustained release of more than 144 h. The optimized formulation had instant in vitro gelation (2.8±0.3 min) with good injectability in comparison to the conventional commercial DTX injectable formulation having instant release (<2 h). Additionally, developed formulation exhibited an improved biodisponibility (25.1±0.2 h) in comparison to the commercially available formulation (1.7±0.1 h). The Solid Tumor Carcinoma model in Swiss albino mice revealed that the optimized formulation (based on gellan gum) showed better tumor reduction (85.7±1.2%) and lower toxicity as compared to the commercial formulation (77.3±1.3%). Pharmacokinetic and biodistribution studies demonstrated 3 to 4 times higher localization of drug in tumors. Our findings suggested that injectable gellan gum-based in situ hydrogel formulation can be an effective delivery system for DTX with enhanced solubility, reduced toxicity, and better targeting to the tumors for improved therapeutics.Graphical abstract.

Abstract
Docetaxel (DTX) is a highly lipophilic, BCS class IV drug with poor aqueous solubility (12.7 µg/mL). Presently, only injectable formulation is available in the market which uses a large amount of surfactant (Tween 80) and dehydrated alcohol as a solubilizer. High concentrations of Tween 80 in injectable formulations are associated with severe consequences i.e. nephrotoxicity, fluid retention, and hypersensitivity reactions. The present study aims to eliminate Tween 80, thus novel biocompatible surfactant Vitamin E TPGS based nanovesicle formulation of DTX (20 mg/mL) was developed and evaluated for different quality control parameters. Optimized nanovesicular formulation (NV-TPGS-3) showed nanometric size (102.9 ± 2.9 nm), spherical vesicular shape, high drug encapsulation efficiency (95.2 ± 0.5%), sustained-release profile and high dilution integrity with normal saline. In vitro cytotoxicity assay, showed threefold elevation in the IC50 value of the optimized formulation in comparison to the commercial formulation. Further, no mortality and toxicity were observed during 28 days repeated dose sub-acute toxicity studies in Swiss albino mice up to the dose of 138 mg/kg, whereas, commercial formulation showed toxicity at 40 mg/kg. In addition, in vivo anticancer activity on Ehrlich Ascites Carcinoma induced mice showed a significant tumour growth inhibition of 76.3 ± 5.3% with the NV-TPGS-3 treatment when compared to Ehrlich Ascites Carcinoma control. Results demonstrated that the developed Vitamin E TPGS based nanovesicular formulation of DTX could be a better alternative to increase its clinical uses with improved therapeutic efficacy, reduced toxicity and dosing frequency, and sustained drug release behaviour.

Breast Cancer Res Treat 2020; 184:397-405.

Abstract
BACKGROUND AND PURPOSE Paclitaxel-based regimens are widely used in the neoadjuvant therapy (NAT) of breast cancer. The purpose is to analysis the efficacy and adverse events (AEs) among common paclitaxel (PTX), docetaxel and liposomal paclitaxel. At the same time, we want to analysis the axillary nodal pathologic complete response (apCR) after NAT among the three groups. METHODS From April 2014 to 2020, 647 breast cancer patients underwent operation after NAT were included in this study. Patients received full course of anthracycline- and paclitaxel-based chemotherapy before surgery. The paclitaxel-based regimens included PTX, docetaxel and liposomal paclitaxel. The therapy efficacy and AEs of the three groups were evaluated. At the same time, the apCR was also analyzed. RESULTS In general, 30.6% (198/647) of patients achieved breast pathologic complete response (bpCR), which was 28.6%, 28.3% and 39.3% among PTX, docetaxel and liposomal paclitaxel group, respectively (p = 0.067). The total pathologic complete response (tpCR) (achieving both bpCR and apCR) was 21.6% (140/647). The tpCR was 13.3%, 19.4% and 34.4% among PTX, docetaxel and liposomal paclitaxel group, respectively (p = 0.026). The multivariate logistic analysis result showed that clinical tumor stage and molecular subtype were significantly associated with tpCR (all p < 0.05). Among 592 clinical positive patients (cN+), the apCR was 39.0% (231/592). The multivariate logistic analysis showed that paclitaxel- based regimens and molecular subtype were indicated as independent predictors for apCR of NAT. The apCR was significantly higher in liposomal paclitaxel group (63.5%) than in PTX (24.6%) and docetaxel group (34.8%) (p < 0.001). The subgroup analysis among different molecular subtypes found that in triple negative (TN) and HER-2 positive (HER2+) subgroup, the apCR in liposomal paclitaxel group was significantly higher than those in PTX and docetaxel group (all p < 0.05). But no significant result was found in the subgroup analysis in hormone receptor positive/HER-2 negative subgroup (p = 0.050). Safety analysis indicated that the incidence of neutropenia (grade III-IV) and peripheral neurotoxicity (grade I-II) was significantly lower in the liposomal paclitaxel group than in the PTX and docetaxel group. The incidence of oral mucositis, anaphylaxis and palmar-plantar erythrodysesthesia syndrome was also much lower in liposomal paclitaxel than other two groups (all p < 0.05). And there was no significant difference in other AEs among the three groups (all p > 0.05). CONCLUSION Liposome paclitaxel had similar tumor suppressor effect compared with PTX and docetaxel in NAT setting. Moreover, it had a better axillary lymph node (ALN) response after NAT than PTX and docetaxel. These patients who received liposome paclitaxel had more chance to avoid ALN dissection after NAT. At the same time, the application of liposome enables liposome paclitaxel could significantly reduce AEs caused by chemotherapy. Therefore, we suggested the application of liposome paclitaxel in the NAT setting, especially for cN+ patients with TN and HER2 + disease.

Abstract
Liposomes are among the most successful nanocarriers; several products have been marketed, all of which were prepared by active loading methods. However, poorly water-soluble drugs without ionizable groups are usually incorporated into the lipid bi-layer of liposomes by passive loading methods, with serious drug leakage during blood circulation. Furthermore, there have been few improvements in their anti-cancer activity and safety. Herein, we designed and synthesized three weak-acid modified paclitaxel (PTX) derivatives with a one-step reaction for the remote loading of liposomal formulations. By comparison, PTX-succinic acid liposomes (PTX-SA LPs) exhibited the highest encapsulation efficiency (97.2 ± 1.8%) and drug loading (8.84 ± 0.16%); meanwhile, there was almost no change in their particle size or zeta potential within one month. Furthermore, compared with Taxol®, the PTX-SA LPs showed a 4.35-fold prolonged half-time, enhanced tumor accumulation, and an increased maximum tolerated dose (MTD) of more than 30 mg kg−1. As a result, the PTX-SA LPs displayed significantly improved in vivo anti-cancer efficacy in comparison with Taxol®. Therefore, weak-acid modification is proved to be a simple and effective method to achieve remote loading and high encapsulation efficiency of poorly soluble drugs, showing great potential for clinical application. A remote loading liposomal formulation of weak-acid paclitaxel derivative with high encapsulation efficiency and high drug loading, improved therapeutic efficiency and negligible toxicity.![]()

Aptamer-Functionalized Drug Nanocarrier Improves Hepatocellular Carcinoma toward Normal by Targeting Neoplastic Hepatocytes. MOLECULAR THERAPY-NUCLEIC ACIDS 2020; 20:34-49. [PMID: 32146417 PMCID: PMC7063179 DOI: 10.1016/j.omtn.2020.01.034] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 01/29/2020] [Accepted: 01/29/2020] [Indexed: 12/14/2022]
Abstract
Site-specific delivery of chemotherapeutics specifically to neoplastic hepatocytes without affecting normal hepatocytes should be a focus for potential therapeutic management of hepatocellular carcinoma (HCC). The aptamer TLS 9a with phosphorothioate backbone modifications (L5) has not been explored so far for preferential delivery of therapeutics in neoplastic hepatocytes to induce apoptosis. Thus, the objective of the present investigation was to compare the therapeutic potential of L5-functionalized drug nanocarrier (PTX-NPL5) with those of the other experimental drug nanocarriers functionalized by previously reported HCC cell-targeting aptamers and non-aptamer ligands, such as galactosamine and apotransferrin. A myriad of well-defined investigations such as cell cycle analysis, TUNEL (terminal deoxynucleotidyltransferase-mediated deoxyuridine triphosphate nick end labeling) assay, and studies related to apoptosis, histopathology, and immunoblotting substantiated that PTX-NPL5 had the highest potency among the different ligand-attached experimental formulations in inducing selective apoptosis in neoplastic hepatocytes via a mitochondrial-dependent apoptotic pathway. PTX-NPL5 did not produce any notable toxic effects in healthy hepatocytes, thus unveiling a new and a safer option in targeted therapy for HCC. Molecular modeling study identified two cell-surface biomarker proteins (tumor-associated glycoprotein 72 [TAG-72] and heat shock protein 70 [HSP70]) responsible for ligand-receptor interaction of L5 and preferential internalization of PTX-NPL5 via clathrin-mediated endocytosis in neoplastic hepatocytes. The potential of PTX-NPL5 has provided enough impetus for its rapid translation from the pre-clinical to clinical domain to establish itself as a targeted therapeutic to significantly prolong survival in HCC.

Abstract
Elastic liposoxy1mes (ELs) are biocompatible bilayer vesicular systems commonly used in the transdermal delivery of drugs. Compared with conventional liposomes (CLs), the strong deformation ability conferred by edge activators (EAs) is one of the most critical properties of ELs. However, due to limited research methods, little is known about the effect of EAs on the deformation abilities of vesicles. In this study, taking sodium cholate as an example, a multiscale study was carried to study the effect of EAs on the deformability of ELs, including in vitro diffusion experiment at macroscale, "vesicle-pore" model experiment at the microscale and flat patch model experiment at the molecular scale. As a result, it was found that sodium cholate could decrease the kc of DPPC bilayer, which enabled it to remain morphologically intact during a strong deformation process. Such kind of differences on deformation ability made pogostone ELs (contain sodium cholate) present a better permeation effect compared with that of pogostone CLs. All of these provide a multiscale and thorough understanding of the effect of sodium cholate on the deformation ability of ELs.

Abstract
The safety of nanomaterials, a crucial consideration for clinical translation, is enhanced by using building blocks that are biologically nontoxic. Here, we used poly(γ-glutamic acid) (γ-PGA) and dopamine as building blocks of polymeric nanomaterials for carrying hydrophobic anticancer drugs. The introduction of phenylalanine onto γ-PGA enabled the resulting amphiphilic derivative of γ-PGA acid to self-assemble in the presence of the anticancer drug paclitaxel (PTX) to form PTX-encapsulated micelles. The surfaces of PTX-loaded micelles were then coated with polymerized dopamine (PDA). The PDA-coated, amphiphilic γ-PGA-based micelles (AM) carrying PTX (PDA/AM/P) exerted near-infrared-responsive photothermal effects. Near-infrared irradiation of cancer cells treated with PDA/AM/P nanoparticles produced a greater anticancer effect than that observed in other treatment groups, indicating a synergistic effect. Intravenous administration of PDA/AM/P completely ablated tumors and prevented their recurrence. Notably, the in vivo safety profile of PDA/AM/P nanoparticles allowed PTX to be delivered at a 3.6-fold higher dose than was possible with PTX solubilized in surfactant, and circumvented the side effects of the surfactant. These results support the multifunctional potential of PDA/AM for the delivery of various hydrophobic drugs and imaging dyes for safe translation of nanomaterials into the clinic.

Abstract
Acylated chitosan (Myristoyl and Octanoyl) coated paclitaxel-loaded liposomal formulation was developed with an aim to overcome the cremophor EL related toxicities. They were evaluated for drug entrapment, in vitro drug release, and cytotoxicity and cell uptake behavior using A549 cells. The 99mTc radio-labeled formulations were also evaluated in vivo in Ehrlich Ascites Tumor (EAT) bearing mice for biodistribution and tumor uptake. The mean particle size of both coated and uncoated liposomal formulations was found to be in the range of 180-200 nm with high drug entrapment efficiency (>90% in case of uncoated liposomes and 80 ± 5% in case of coated liposomes). The uncoated liposomes displayed negative zeta potential (-10.5 ± 4.9 mV) whereas coated liposomes displayed positive zeta potential in the range of +21 to +27 mV. Slower drug release was observed in case of liposomes coated with acylated chitosans as compared to uncoated and native chitosan coated liposomes. All liposomal formulations were found less cytotoxic than paclitaxel injection (Celtax™, Celon Labs, India). In vitro cell uptake and intracellular distribution studies confirmed the cytosolic delivery of uncoated and coated liposomes. The myristoyl chitosan coated liposomal system (LMC) exhibited improved pharmacokinetic, biodistribution and tumor uptake characteristics over other formulations. These obtained results confirmed the potential application of acylated chitosn coated liposomal delivery systems (LMC) in tumor targeting of paclitaxel and other drugs.

Abstract
Elastic liposomes (EL) are some of the most versatile deformable vesicular carriers that comprise physiologically biocompatible lipids and surfactants for the delivery of numerous challenging molecules and have marked advantages over other colloidal systems. They have been investigated for a wide range of applications in pharmaceutical technology through topical, transdermal, nasal, and oral routes for efficient and effective drug delivery. Increased drug encapsulation efficiency, enhanced drug permeation and penetration into or across the skin, and ultradeformability have led to widespread interest in ELs to modulate drug release, permeation, and drug action more efficiently than conventional drug-release vehicles. This review provides insights into the versatile role that ELs play in the delivery of numerous drugs and biomolecules by improving drug release, permeation, and penetration across the skin as well as stability. Furthermore, it provides future directions that should ensure the widespread use of ELs across all medical fields.

Abstract
The aim of this study was to examine the efficacy of self-nano phospholipid dispersions (SNPDs) based on Phosal(®) to improve the oral bioavailability of curcumin (CUR). SNPDs were prepared with Phosal(®) 53 and Miglyol 812 at different surfactant ratio. Formulations were evaluated for particle size, polydispersity index, zeta potential, and robustness toward dilution, TEM as well as in vitro drug release. The in vivo oral absorption of selected formulations in comparison to drug suspension was evaluated in rats. Moreover, formulations were assessed for in vitro characteristic changes before and after storage. The SNPDs were miscible with water in any ratio and did not show any phase separation or drug precipitation. All the formulas were monodisperse with nano range size from 158±2.6 nm to 610±6.24 nm. They passed the pharmacopeial tolerance for CUR dissolution. No change in dissolution profile and physicochemical characteristics was detected after storage. CUR-SNPDs are found to be more bioavailable compared with suspension during an in vivo study in rats and in vitro release studies failed to imitate the in vivo conditions. These formulations might be new alternative carriers that enhance the oral bioavailability of poorly water-soluble molecules, such as CUR.

Abstract
OBJECTIVES The aim of this study was to develop the hexapeptide-conjugated active targeting micelles for delivery of doxorubicin (DOX) and paclitaxel (PTX) to EGFR high-expressed cancer cells. METHODS A hexapeptide, which mimicked the EGFR, was applied as a targeting ligand. The active targeting micelles were prepared using the synthesized poly(D,L-lactide-co-glycolide)-PEG copolymer conjugated with the hexapeptide. The micelles were used for encapsulating DOX and/or PTX, and the cellular uptake, in vitro drug release and cellular viability of drug-loaded peptide-conjugated and peptide-free micelles were investigated. RESULTS The particle size of drug-loaded peptide-conjugated and peptide-free micelles was < 150 nm with narrow size distribution. The uptake of peptide-conjugated micelles was more efficient in EGFR high-expressed MDA-MB-468 and SKOV3 cells than in EGFR low-expressed HepG2 cells. The in vitro release of DOX and PTX was faster in pH 4.0 (500 U lipase) than in pH 7.4 release medium. The cytotoxicity in terms of IC50 of DOX/PTX-loaded peptide-conjugated micelles was 4.8-folds lower than that of peptide-free micelles and 18.2-folds lower than DOX/PTX drug solution in SOKV3 cells. CONCLUSION The peptide-conjugated micelles acted as a nanocarrier to increase intracellular accumulation of anticancer drugs in EGFR high-expressed SKOV3 cancer cells to enhance cell cytotoxicity.

Abstract
INTRODUCTION With the incorporation of edge activators into the lipid bilayer structure, elasticity properties are given to liposomes. Regardless of the debate over the precise permeation mechanism of elastic liposomes, these vesicles have been proven to enhance drug permeation into or through skin in most cases. AREAS COVERED This article provides an overview of the formulation ingredients of elastic liposomes and their relationship with skin permeation behavior. The ingredients are divided into two categories of basic and optional ingredients. The effect of stability on permeation behavior of the vesicles is highlighted. EXPERT OPINION More attention should be paid to the stability of elastic liposomes. The different stability properties of the elastic liposomes following administration can induce different skin permeation behaviors of the vesicles. It is necessary to select the optimum composition of the elastic liposomes in order to control the stability and permeation behavior of the vesicles into or through the skin. Moreover, for the development of elastic liposomes, particular attention should also be paid to the drug leakage from the vesicles during long-term storage. The application of optional ingredients to improve the stability and/or elasticity of the elastic liposomes is becoming a new trend.
