Abstract
Direct cytosolic delivery of the Cas9 ribonucleoprotein is the most promising method for inducing CRISPR-Cas9 genome editing in mammalian cells. Recently, we focused the movable properties of cyclodextrin-based polyrotaxanes (PRXs), which consist of numerous cyclodextrins threaded onto the axile molecule with bulky endcaps at both ends of the axile molecule, and developed aminated PRXs as multistep transformable carriers for Cas9 ribonucleoprotein, ensuring efficient complexation, cellular internalization, endosomal escape, release, and nuclear localization. This study reports the structural fine-tuning and structure-property relationship of multistep transformable PRXs for more efficient Cas9 ribonucleoprotein delivery. Among various PRXs, PRX derivatives with a longer molecular length (35 kDa polyethylene glycol as the axile molecule) and a low total degree of substitution (1.5 amino groups/α-cyclodextrins), as well as the modified ratio of two modified amines (cystamine and diethylenetriamine) = ≈1:1, exhibited the highest genome-editing efficacy and intracellular dynamics control. These structural properties are important for efficient endosomal escape and Cas9 RNP release. Furthermore, ligand-modified-β-CD, which can endow the ligand through complexation with PRX termini, improved the cellular uptake and genome-editing effects of the optimized PRX/Cas9 RNP in target cells. Thus, structural fine-tuning and the addition of ligand-modified-β-cyclodextrin enabled efficient genome editing by the Cas9 RNP.

Abstract
The domain of nanomedicine owns a wide-ranging variety of lipid-based drug carriers, and novel nanostructured drug carriersthat are further added to this range every year. The primary goal behind the exploration of any new lipid-based nanoformulation is the improvement of the therapeutic index of the concerned drug molecule along with minimization in the associated side-effects. However, for maintaining a sustained delivery of these intravenously injected lipoidal nanomedicines to the targeted tissues and organ systems in the body, longer circulation in the bloodstream, as well as their stability, are important. After administration, upon recognition as foreign entities in the body, these systems are rapidly cleared by the cells associated with the mononuclear phagocyte system. In order to provide these lipid-based systems with long circulation characteristics, techniques such as coating of the lipoidal surface with an inert polymeric material like polyethylene glycol (PEG) assists in imparting 'stealth properties' to these nanoformulations for avoiding recognition by the macrophages of the immune system. In this review, detailed importance is given to the hydrophilic PEG polymer and the role played by PEG-linked lipid polymers in the field of nanomedicine-based drug carriers. The typical structure and classification of stealth lipids, clinical utility, assemblage techniques, physicochemical characterization, and factors governing the in-vivo performance of the PEG-linked lipids containing formulations will be discussed. Eventually, the novel concept of accelerated blood clearance (ABC) phenomenon associated with the use of PEGylated therapeutics will be deliberated.

Abstract
pH-sensitive liposomes are interesting carriers for drug-delivery, undertaking rapid bilayer destabilization in response to pH changes, allied to tumor accumulation, a desirable behavior in the treatment of cancer cells. Previously, we have shown that pH-sensitive liposomes accumulate in tumor tissues of mice, in which an acidic environment accelerates drug delivery. Ultimately, these formulations can be internalized by tumor cells and take the endosome-lysosomal route. However, the mechanism of doxorubicin release and intracellular traffic of pH-sensitive liposomes remains unclear. To investigate the molecular mechanisms underlying the intracellular release of doxorubicin from pH-sensitive liposomes, we followed HeLa cells viability, internalization, intracellular trafficking, and doxorubicin's intracellular delivery mechanisms from pH-sensitive (SpHL-DOX) and non-pH-sensitive (nSpHL-DOX) formulations. We found that SpHL-DOX has faster internalization kinetics and intracellular release of doxorubicin, followed by strong nuclear accumulation compared to nSpHL-DOX. The increased nuclear accumulation led to the activation of cleaved caspase-3, which efficiently induced apoptosis. Remarkably, we found that chloroquine and E64d enhanced the cytotoxicity of SpHL-DOX. This knowledge is paramount to improve the efficiency of pH-sensitive liposomes or to be used as a rational strategy for developing new formulations to be applied in vivo.

Abstract
The colloidal stability, in vitro toxicity, cell association, and in vivo pharmacokinetic behavior of liposomes decorated with monomethoxy-poly(ethylene glycol)-lipids (mPEG-lipids) with different chemical features were comparatively investigated. Structural differences of the mPEG-lipids used in the study included: (a) surface-anchoring moiety [1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE), cholesterol (Chol), and cholane (Chln)]; (b) mPEG molecular weight (2 kDa mPEG45 and 5 kDa mPEG114); and (c) mPEG shape (linear and branched PEG). In vitro results demonstrated that branched (mPEG114)2-DSPE confers the highest stealth properties to liposomes (∼31-fold lower cell association than naked liposomes) with respect to all PEGylating agents tested. However, the pharmacokinetic studies showed that the use of cholesterol as anchoring group yields PEGylated liposomes with longer permeance in the circulation and higher systemic bioavailability among the tested formulations. Liposomes decorated with mPEG114-Chol had 3.2- and ∼2.1-fold higher area under curve (AUC) than naked liposomes and branched (mPEG114)2-DSPE-coated liposomes, respectively, which reflects the high stability of this coating agent. By comparing the PEGylating agents with same size, namely, linear 5 kDa PEG derivatives, linear mPEG114-DSPE yielded coated liposomes with the best in vitro stealth performance. Nevertheless, the in vivo AUC of liposomes decorated with linear mPEG114-DSPE was lower than that obtained with liposomes decorated with linear mPEG114-Chol. Computational molecular dynamics modeling provided additional insights that complement the experimental results.

Abstract
Liposomes are lipid vesicles widely used as nanocarriers in targeted drug delivery systems for therapeutic and/or diagnostic purposes. A strategy to prolong the blood circulation time of the liposomes includes the addition of a hydrophilic polymer polyethylene glycol (PEG) moiety onto the surface of the vesicle. Several studies claim that liposome PEGylation by a single chain length or a combination of PEG with different chain lengths may alter the liposomes' pharmacokinetic properties. Therefore, the purpose of this study was to evaluate the influence of PEG on the biodistribution of pH-sensitive liposomes in a tumor-bearing animal model. Three liposomal formulations (PEGylated or not) were prepared and validated to have a similar mean diameter, monodisperse distribution, and neutral zeta potential. The pharmacokinetic properties of each liposome were evaluated in healthy animals, while the biodistribution and scintigraphic images were evaluated in tumor-bearing mice. High tumor-to-muscle ratios were not statistically different between the PEGylated and non-PEGylated liposomes. While PEGylation is a well-established strategy for increasing the blood circulation of nanostructures, in our study, the use of polymer coating did not result in a better in vivo profile. Further studies must be carried out to confirm the feasibility of the non-PEGylated pH-sensitive liposomes for tumor treatment.

Abstract
To inhibit hepatic ischemia/reperfusion injury, we developed polyethylene glycol (PEG) conjugated (PEGylated) cysteine-modified lysine dendrimers with multiple reduced thiols, which function as scavengers of reactive oxygen species (ROS). Second, third, and fourth generation (K2, K3, and K4) highly branched amino acid spherical lysine dendrimers were synthesized, and cysteine (C) was conjugated to the outer layer of these lysine dendrimers to obtain K2C, K3C, and K4C dendrimers. Subsequently, PEG was reacted with the C residues of the dendrimers to obtain PEGylated dendrimers with multiple reduced thiols (K2C-PEG, K3C-PEG, and K4C-PEG). Radiolabeled K4C-PEG ((111)In-K4C-PEG) exhibited prolonged retention in the plasma, whereas (111)In-K2C-PEG and (111)In-K3C-PEG rapidly disappeared from the plasma. K4C-PEG significantly prevented the elevation of plasma alanine aminotransferase (ALT) activity, an index of hepatocyte injury, in a mouse model of hepatic ischemia/reperfusion injury. In contrast, K2C-PEG, K3C-PEG, l-cysteine, and glutathione, the latter two of which are classical reduced thiols, hardly affected the plasma ALT activity. These findings indicate that K4C-PEG with prolonged circulation time is a promising compound to inhibit hepatic ischemia/reperfusion injury.

Abstract
PURPOSE A novel brain targeting drug delivery system based on OX26 antibody conjugation on PEGylated cationic solid lipid nanoparticles (OX26-PEG-CSLN) was prepared. METHODS The Baicalin-loaded PEGylated cationic solid lipid nanoparticles modified by OX26 antibody (OX26-PEG-CSLN) were prepared by emulsion evaporation-solidification at low temperature method. The immune-gold labeled OX26-PEG-CSLN was visualized by transmission electron microscopy. The mean diameter and zeta potential of OX26-PEG-CSLN, PEG-CSLN and CSLN were determined using a Zetasizer. The entrapment efficiency of OX26-PEG-CSLN, PEG-CSLN and CSLN was determined by ultrafiltration centrifugation method. And the solid-state characterization of OX26-PEG-CSLN and CSLN were analyzed by X-ray. Pharmacokinetics studies were conducted by in vivo microdialysis in rat cerebrospinal fluid. RESULTS The results showed that the OX26-PEG-CSLN, PEG-CSLN and CSLN had average diameters of 47.68 ± 1.65, 27.20 ± 1.70 and 33.89 ± 5.74 nm, Zeta potentials of -0.533 ± 0.115 mV, 11.200 ± 0.500 mV and 11.080 ± 1.170 mV and entrapment efficiencies of 83.03 ± 0.01%, 92.90 ± 3.50% and 97.83 ± 0.19%, respectively. In the pharmacokinetics studies, the AUC value of OX26-PEG-CSLN was11.08-fold higher than that of the Baicalin solution (SOL) (p<0.01), and 1.12-fold higher than that of the CSLN (p>0.05); the Cmax value of OX26-PEG-CSLN was 7.88-fold higher than that of SOL (p<0.01) and 1.12-fold (p<0.01) higher than that of the CSLN, respectively. CONCLUSION These results demonstrated OX26-PEG-CSLN could be a promising carrier to deliver drugs across the BBB for the treatment of brain diseases.

Abstract
Bioavailability of baicalin (BAI), an example of traditional Chinese medicine, has been modified by loading into liposome. Several liposome systems of different composition i.e., lipid/cholesterol (L), long-circulating stealth liposome (L-PEG) and folate receptor (FR)-targeted liposome (L-FA) have been used as the drug carrier for BAI. The obtained liposomes were around 80 nm in diameter with proper zeta potentials about -25 mV and sufficient physical stability in 3 months. The entrapment efficiency and loading efficiency of BAI in the liposomes were 41.0-46.4% and 8.8-10.0%, respectively. The morphology details of BAI lipsosome systems i.e., formation of small unilamellar vesicles, have been determined by cryogenic transmission electron microscopy (cryo-TEM) and small angle X-ray scattering (SAXS). In vitro cytotoxicity of BAI liposomes against HeLa cells was evaluated by MTT assay. BAI loaded FR-targeted liposomes showed higher cytotoxicity and cellular uptake compared with non-targeted liposomes. The results suggested that L-FA-BAI could enhance anti-tumor efficiency and should be an effective FR-targeted carrier system for BAI delivery.

Therefore, we developed polyethylene glycol-conjugated bovine serum albumin with multiple reduced thiols (PEG-BSA-SH) for the treatment of fulminant hepatic failure. As a long-circulating ROS scavenger, PEG-BSA-SH effectively scavenged highly reactive oxygen species and hydrogen peroxide in buffer solution. PEG-BSA-SH showed a long circulation time in the plasma after intravenous injection into mice. Fulminant hepatic failure was induced by intraperitoneal injection of lipopolysaccharide and D-galactosamine (LPS/D-GalN) into mice. The LPS/D-GalN-induced elevation of plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels was significantly inhibited by a bolus intravenous injection of PEG-BSA-SH. Furthermore, the changes in hepatic lipid peroxide and hepatic blood flow were effectively suppressed by PEG-BSA-SH. In contrast, L-cysteine, glutathione, and dithiothreitol, three traditional reduced thiols, had no statistically significant effects on the serum levels of ALT or AST. These findings indicate that PEG-BSA-SH is a promising ROS scavenger and useful in the treatment of fulminant hepatic failure.

Mixed polyethylene glycol-modified breviscapine-loaded solid lipid nanoparticles for improved brain bioavailability: preparation, characterization, and in vivo cerebral microdialysis evaluation in adult Sprague Dawley rats. AAPS PharmSciTech 2014; 15:483-96. [PMID: 24482026 DOI: 10.1208/s12249-014-0080-4] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2013] [Accepted: 01/07/2014] [Indexed: 11/30/2022] Open
Abstract
Breviscapine is used in the treatment of ischemic cerebrovascular diseases, but it has a low bioavailability in the brain due to its poor physicochemical properties and the activity of P-glycoprotein efflux pumps located at the blood-brain barrier. In the present study, breviscapine-loaded solid lipid nanoparticles (SLN) coated with polyethylene glycol (PEG) derivatives were formulated and evaluated for their ability to enhance brain bioavailability. The SLNs were either coated with polyethylene glycol (40) (PEG-40) stearate alone (Bre-GBSLN-PS) or a mixture of PEG-40 stearate and 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-PEG2000 (DSPE-PEG2000) (Bre-GBSLN-PS-DSPE) and were characterized both in vitro and in vivo. The mean particle size, polydispersity index, and entrapment efficiency for Bre-GBSLN-PS and Bre-GBSLN-PS-DSPE were 21.60 ± 0.10 and 22.60 ± 0.70 nm, 0.27 ± 0.01 and 0.26 ± 0.04, and 46.89 ± 0.73% and 47.62 ± 1.86%, respectively. The brain pharmacokinetic parameters revealed that the brain bioavailability of breviscapine from the Bre-GBSLN-PS and Bre-GBSLN-PS-DSPE was significantly enhanced (p < 0.01) with the area under concentration-time curve (AUC) of 1.59 ± 0.39 and 1.42 ± 0.58 μg h/mL of breviscapine, respectively, in comparison to 0.11 ± 0.02 μg h/mL from the commercial breviscapine injection. The ratios of the brain AUC for scutellarin in comparison with the plasma scutellarin AUC for commercial breviscapine injection, Bre-GBSLN-PS, and Bre-GBSLN-PS-DSPE were 0.66%, 2.82%, and 4.51%, respectively. These results showed that though both SLN formulations increased brain uptake of breviscapine, Bre-GBSLN-PS-DSPE which was coated with a binary combination of PEG-40 stearate and DSPE-PEG2000 had a better brain bioavailability than Bre-GBSLN-PS. Thus, the coating of SLNs with the appropriate PEG derivative combination could improve brain bioavailability of breviscapine and can be a promising tool for brain drug delivery.

Abstract
Liposomes are used as a delivery vehicle for drug molecules and imaging agents. The major impetus in their biomedical applications comes from the ability to prolong their circulation half-life after administration. Conventional liposomes are easily recognized by the mononuclear phagocyte system and are rapidly cleared from the blood stream. Modification of the liposomal surface with hydrophilic polymers delays the elimination process by endowing them with stealth properties. In recent times, the development of various materials for surface engineering of liposomes and other nanomaterials has made remarkable progress. Poly(ethylene glycol)-linked phospholipids (PEG-PLs) are the best representatives of such materials. Although PEG-PLs have served the formulation scientists amazingly well, closer scrutiny has uncovered a few shortcomings, especially pertaining to immunogenicity and pharmaceutical characteristics (drug loading, targeting, etc.) of PEG. On the other hand, researchers have also begun questioning the biological behavior of the phospholipid portion in PEG-PLs. Consequently, stealth lipopolymers consisting of non-phospholipids and PEG-alternatives are being developed. These novel lipopolymers offer the potential advantages of structural versatility, reduced complement activation, greater stability, flexible handling and storage procedures and low cost. In this article, we review the materials available as alternatives to PEG and PEG-lipopolymers for effective surface modification of liposomes.

Abstract
Cholesterol anchored derivatives of 5-Cholestene-3-beta-ol 3-hemisuccinate (CHO-HS) and 1-cholesteryl-4-ω-methoxy-polyethylene glycol succinate (CHO-PEG) have been synthesized via esterification and employed at various ratios with di-stearoylphosphatidylcholine (DSPC) in the preparation of anionic long-circulating nanoliposmes for cisplatin (CDDP) delivery. In the present study, CHO-HS and CHO-PEG were characterized by FTIR and (1)H NMR. The particle size and zeta potential of liposomes were determined by Dynamic lights scattering (DLS). The obtained liposomes have concentratedly distributed nanosizes around 100 nm and proper zeta potentials between -39.7 mV and -3.18 mV and good physical stability in test period of 28 days. Fine morphology of the liposomal vesicles can be observed via transmission electron microscopy (TEM). The CDDP encapsulating percentage of liposomes was 43-94% and loading efficiency was 7.5-29.3%, depending on the presence or absence of CHO-HS and CHO-PEG. In addition, the in vitro drug release behaviors, in vitro cytotoxicity against HeLa cells and 293T cells and in vivo CDDP distribution of CDDP loaded CHO-HS/CHO-PEG liposomes were evaluated. The results suggest that CHO-HS/CHO-PEG nanoliposomes represent a promising strategy for the CDDP delivery as an effective long-circulating drug carrier system which may reduce the acute renal toxicity.

Abstract
For the purpose of systemic delivery of siRNA, we previously developed polycation liposomes (PCLs) containing dicetylphosphate-tetraethylenepentamine (DCP-TEPA) as an effective siRNA carrier. In the present study, to endow these PCLs (TEPA-PCL) actively target cancer cells and angiogenic vessels, we decorated the PCLs with cyclic RGD, by using cyclic RGD-grafted distearoylphosphatidylethanolamine-polyethylene glycol (DSPE-PEG), and investigated the usefulness of this type of carrier (RGD-PEG-PCL) for active targeting. Firstly, the gene-silencing efficacy of siRNA for luciferase (siLuc2) formulated in RGD-PEG-PCL (RGD-PEG-PCL/siLuc2) was examined in vitro by using B16F10-luc2 murine melanoma cells stably expressing the luciferase 2 gene, where the siRNA was grafted with cholesterol at the 3'-end of the sense strand (siRNA-C) for the stable association of the siRNA with the PCL. RGD-PEG-PCL/siLuc2 showed high knockdown efficiency compared with siLuc2 formulated in PEGylated TEPA-PCL without cyclic RGD (PEG-PCL). Next, the gene-silencing efficacy of RGD-PEG-PCL/siLuc2 was examined in vivo by use of B16F10-luc2 lung metastatic model mice. The intravenous injection of RGD-PEG-PCL/siLuc2 showed high knockdown efficiency against metastatic B16F10-luc2 tumors in the lungs of the mice, as assessed with an in vivo imaging system. These data strongly suggest that systemic and active targeting siRNA delivery using RGD-PEG-PCL is useful for cancer RNAi therapy.

Abstract
PURPOSE The objective of this study was to achieve a sustained and targeted delivery of liposome to the liver, by modifying the phospholipid [phosphatidylcholine (PC)/cholesterol (10 : 1) liposomes with a novel polymer bile salts-(polyethylene glycol)(2000)-bile salts (BP(2)B). METHODS First, we generated a novel BP(2)B by N,N'-dicyclohexylcarbodiimide/4-dimethylaminopyridine esterification method and confirmed by Fourier transform infraredand (1) H-NMR spectra. Second, we prepared the BP(2)B-modified liposomes (BP(2)BL) that included BP(2)B, and the effect of the weight ratios of BP(2)B/PC on entrapment efficiency was investigated and BP(2)B/PC = 3% (w/w) was determined as the optimum ratio for the 4,4'-dimethoxy-5,6,5',6'-bi (methylenedioxy)-2,2'-bicarbomethoxybiphenyl liposomes. And then, the ability of the liver target of BP(2)BL was studied by calculating the targeted parameters. RESULTS AND DISCUSSION All the results revealed that the introduction of polyoxyethylene chains could control interactions of bile salt moieties on liposome surfaces with the receptor compared with traditional liposomes (CL), marking BP(2)BL as a suitable carrier for hepatic parenchymal cell-specific and sustained targeting. It was suggested that liposomes containing such novel BP(2)B have great potential as drug delivery carriers for the liver-selective targeting that has targeted and sustained drug delivery.
