Abstract
Methylated β-cyclodextrin (MβCD) can extract cholesterol from lipid rafts and induce apoptosis in cancer cells by inhibiting activation of the PI3K-Akt-Bad pathway. In this study, we modified MβCD with mannose (Man-MβCD) and assessed its in vitro and in vivo potential for targeting colon cancer cells expressing the mannose receptor (MR) and tumor-associated macrophages (TAM). Man-MβCD showed a significantly greater level of cellular association with colon-26 cells and M2 macrophages, and much more prominent anticancer activity than that of MβCD against MR-positive colon-26 cells. These results revealed that autophagy was the main mechanism of cell death associated with Man-MβCD. Furthermore, compared with MβCD, Man-MβCD significantly reduced tumor development following intravenous delivery to tumor-bearing mice, with no apparent side effects. Thus, Man-MβCD has the potential to be a novel anticancer drug.

Int J Pharm X 2022; 4:100118. [PMID: 35602759 PMCID: PMC9117884 DOI: 10.1016/j.ijpx.2022.100118] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Accepted: 05/07/2022] [Indexed: 11/25/2022] Open
Abstract
This work aimed to develop water-based formulations for onychomycosis topical treatment using micelles of small pegylated surfactants associated with α-cyclodextrin (αCD) to deliver terbinafine to the nail. Kolliphor® RH40 (RH40) and Gelucire® 48/16 (GEL) single and mixed micelles (RH40:GEL 1:1) were prepared. αCD was added to the surfactants dispersions to form poly(pseudo)rotaxanes (PPR). Formulations were characterized in terms of drug solubilization (3 to 34-fold increase), particle size (9–11 nm) and Z-potential (+0.3 − +1.96 mV), blood compatibility (non-hemolytic), rheological behavior (solid-like viscoelastic properties after 5–10% αCD addition), drug release and interaction with the nail plate. GEL micelles and surfactant-10% αCD PPRs notably hydrated the nail plate. The high viscosity of PPR led to a slower drug release, except for RH40:GEL +10% αCD that surprisingly released terbinafine faster. The RH40:GEL +10% αCD formulation delivered twice more amount of terbinafine to deeper regions of nail plate compared to other formulations. The results evidenced the potential of PPR formed by small pegylated surfactants as a water-based formulation for nail drug delivery. RH40, GEL and their mixed micelles increased 3-fold and 34-fold TB solubility in water and citrate buffer, respectively. Addition of αCD (5–10%) led to PPR formation and viscoelastic supramolecular gels without decrease in TB solubilization. PPR formulations with 10% αCD enhanced nail plate hydration, increasing its porosity. Compared to mixed micelles, PRP showed slower release rate but promoted TB accumulation in deeper regions of hooves.

Abstract
Cyclodextrins are garnering increasing attention because they offer several benefits. For instance, cyclodextrins can form several complexes and supramolecular structures not only for food packaging but also for applications in other fields of science. In this review, we discussed the physical and chemical properties of cyclodextrins and the mechanism of their inclusion complex formation. The use of cyclodextrins in various types of food packaging is elaborated upon. We also explain the effects of cyclodextrins on the packaging of fruits, vegetables, meat, fish, and processed foods. Furthermore, some feasible suggestions for future applications are provided. In addition to the positive attributes of cyclodextrins, there are some limitations and drawbacks, which are discussed briefly in this review. In summary, this review can serve as a guide for researchers exploring cyclodextrins for the development of various packaging films.

Abstract
Foam cells with the pro-inflammatory macrophage phenotype (M1) play an essential role in atherosclerosis progression. Either cellular cholesterol removal or drug intervention was reported to polarize M1 into the anti-inflammatory phenotype (M2) for atherosclerosis regression. These might be realized simultaneously by drug-loaded discoidal reconstituted high-density lipoproteins (d-rHDLs) with the functions of cellular cholesterol efflux and targeted drug delivery on macrophages. However, cholesterol reception can drive the remodelling of d-rHDLs, which serves to release drugs specifically in the atherosclerotic plaque but might incur premature drug leakage in blood circulation. Given that, the proposed strategy is to inhibit the remodelling behaviour of the carrier in blood circulation and responsively accelerate it under the atherosclerotic microenvironmental stimulus. Herein, atorvastatin calcium-loaded d-rHDL was modified by a PEGylated ferrocene/β-cyclodextrin supramolecular copolymer (PF/TC) to construct ROS-responsive PF/TC-AT-d-rHDL, which is expected to possess plasma stability and biosafety as well as triggered drug release by cholesterol efflux promotion. As a result, PF/TC-AT-d-rHDL could responsively dissemble into β-cyclodextrin modified AT-d-rHDL under the ROS-triggered dissociation of PF/TC, therefore exhibiting increased cholesterol efflux from the cholesterol donor and drug release through the remodelling behaviour of the carrier in vitro. Moreover, PF/TC-AT-d-rHDL enhanced cellular cholesterol removal in foam cells after response to ROS, inhibiting intracellular lipid deposition compared with other d-rHDL carriers. Interestingly, cellular drug uptake was significantly promoted upon cellular cholesterol removal by restoring the permeability and fluidity of foam cell membranes as indicated by flow cytometry and fluorescence polarization analysis, respectively. Importantly, compared with untreated foam cells, PF/TC-AT-d-rHDL obviously increased the ratio of M2/M1 by 6.3-fold, which was even higher than the effect of PF/TC-d-rHDL (3.4-fold) and free drugs (1.9-fold), revealing that PF/TC-AT-d-rHDL synergistically promoted the M2 polarization of macrophages. Accordingly, PF/TC-AT-d-rHDL boosted the secretion of anti-inflammatory cytokines and inhibited that of inflammatory cytokines. Collectively, PF/TC-AT-d-rHDL exerted synergistic M2 polarization effects on foam cells for atherosclerotic immunomodulatory therapy via responsively mediating cholesterol efflux and delivering drugs.

Abstract
The incidence of heart failure (HF) is increasing worldwide and myocardial infarction (MI), which follows ischemia and reperfusion (I/R), is often at the basis of HF development. Nanocarriers are interesting particles for their potential application in cardiovascular disease. Impaired drug delivery in ischemic disease is challenging. Cyclodextrin nanosponges (NS) can be considered innovative tools for improving oxygen delivery in a controlled manner. This study has developed new α-cyclodextrin-based formulations as oxygen nanocarriers such as native α-cyclodextrin (α-CD), branched α-cyclodextrin polymer (α-CD POLY), and α-cyclodextrin nanosponges (α-CD NS). The three different α-CD-based formulations were tested at 0.2, 2, and 20 µg/mL to ascertain their capability to reduce cell mortality during hypoxia and reoxygenation (H/R) in vitro protocols. H9c2, a cardiomyoblast cell line, was exposed to normoxia (20% oxygen) or hypoxia (5% CO2 and 95% N2). The different formulations, applied before hypoxia, induced a significant reduction in cell mortality (in a range of 15% to 30%) when compared to samples devoid of oxygen. Moreover, their application at the beginning of reoxygenation induced a considerable reduction in cell death (12% to 20%). α-CD NS showed a marked efficacy in controlled oxygenation, which suggests an interesting potential for future medical application of polymer systems for MI treatment.

Abstract
Autophagy plays a pivotal role in the development and prevention of numerous diseases, and the induction of autophagy is regarded as a potential therapeutic approach for intractable diseases. In this study, the induction of autophagy by methylated β-cyclodextrins (Me-β-CDs)-threaded acid-labile polyrotaxane (Me-PRX) that can release the threaded Me-β-CDs in response to acidic pH in lysosomes was investigated. We hypothesized that the Me-β-CDs released from the Me-PRX interact with the membrane of organelles and cause autophagy. The Me-PRX preferentially accumulated in endoplasmic reticulum (ER) and caused ER stress, which was confirmed by gene expression analysis and the expression of an ER stress-marker protein. Accompanying the ER stress, cells treated with Me-PRX showed autophagy, which was not observed in cells treated with non-labile Me-PRX, other chemically modified PRXs, or free Me-β-CD. Furthermore, the Me-PRX treatment induced autophagic cell death and caused cell death even in apoptosis-resistant cells. Overall, this study demonstrates that the acid-labile Me-PRX induces ER stress-mediated autophagic cell death, and the Me-PRX would be a promising candidate to induce effective cell death in apoptosis-resistant malignant tumors.

Abstract
In the field of host-guest chemistry, some of the most widely used hosts are probably cyclodextrins (CDs). As CDs are able to increase the water solubility of numerous drugs by inclusion into their hydrophobic cavity, they have been widespread used to develop numerous pharmaceutical formulations. Nevertheless, CDs are also able to interact with endogenous substances that originate from an organism, tissue or cell. These interactions can be useful for a vast array of topics including cholesterol manipulation, treatment of Alzheimer's disease, control of pathogens, etc. In addition, the use of natural CDs offers the great advantage of avoiding or reducing the use of common petroleum-sourced drugs. In this paper, the general features and applications of CDs have been reviewed as well as their interactions with isolated biomolecules leading to the formation of inclusion or exclusion complexes. Finally, some potential medical applications are highlighted throughout several examples.

Abstract
BACKGROUND AND PURPOSE Hematoma clearance occurs in the days after intracerebral hemorrhage (ICH) and has not been well studied. In the current study, we examined changes in the hematoma in a piglet ICH model. The effect of deferoxamine on hematoma was also examined. METHODS The ICH model was induced by an injection of autologous blood into the right frontal lobe of piglets. First, a natural time course of hematoma changes ≤7 days was determined. Second, the effect of deferoxamine on hematoma changes was examined. Hemoglobin and membrane attack complex levels in the hematoma were examined by enzyme-linked immunosorbent assay. Immunohistochemistry and Western blotting were used to examine CD47 (a regulator of erythrophagocytosis), CD163 (a hemoglobin scavenger receptor), and heme oxygenase-1 (a heme degradation enzyme) in the clot. RESULTS After ICH, there was a reduction in red blood cell diameter within the clot with time. This was accompanied by membrane attack complex accumulation and decreased hemoglobin levels. Erythrophagocytosis occurred in the hematoma, and this was associated with reduced clot CD47 levels. Activated macrophages/microglia were CD163 and hemeoxygenase-1 positive, and these accumulated in the clot with time. Deferoxamine treatment attenuated the process of hematoma resolution by reducing member attack complex formation and inhibiting CD47 loss in the clot. CONCLUSIONS These results indicate that membrane attack complex and erythrophagocytosis contribute to hematoma clearance after ICH, which can be altered by deferoxamine treatment.

Abstract
Melanoma is a life-threatening disorder and its incidence is increasing gradually. Despite the numerous treatment approaches, conventional systemic chemotherapy has not reduced the mortality rate among melanoma patients, probably due to the induction of toxicity to normal tissues. Recently, we have developed folate-conjugated methyl-β-cyclodextrin (FA-M-β-CyD) and clarified its potential as a new antitumor agent involved in autophagic cell death. However, it remains uncertain whether FA-M-β-CyD exerts anticancer effects against melanomas. Therefore, in this study, we investigated the effects of FA-M-β-CyD on the folate receptor-α (FR-α)-expressing melanoma cell-selective cytotoxic effect. FA-M-β-CyD showed cytotoxic effects in Ihara cells, a human melanoma cell line expressing FR-α. In sharp contrast to methyl-β-cyclodextrin, FA-M-β-CyD entered Ihara cells [FR-α(+)] through FR-α-mediated endocytosis. Additionally, FA-M-β-CyD elicited the formation of autophagosomes in Ihara cells. Notably, FA-M-β-CyD suppressed melanoma growth in BALB/c nude recombinase-activating gene-2 (Rag-2)/Janus kinase 3 (Jak3) double deficient mice bearing Ihara cells. Therefore, these results suggest that FA-M-β-CyD could be utilized as a potent anticancer agent for melanoma chemotherapy by regulating autophagy.

Evaluation of the Cytotoxicity of α-Cyclodextrin Derivatives on the Caco-2 Cell Line and Human Erythrocytes. Molecules 2015; 20:20269-85. [PMID: 26569209 PMCID: PMC6332255 DOI: 10.3390/molecules201119694] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2015] [Revised: 10/29/2015] [Accepted: 11/02/2015] [Indexed: 11/25/2022] Open
Abstract
Cyclodextrins, even the 6-membered α-cyclodextrin, are approved in the various pharmacopoeias as pharmaceutical excipients for solubilizing and stabilizing drugs as well as for controlling drug release. Recently α-cyclodextrin has also been marketed as health food with beneficial effects on blood lipid profiles. However, the concentration of α-cyclodextrin used may be very high in these cases, and its toxic attributes have to be seriously considered. The objective of this study was to investigate the cytotoxicity of various, differently substituted α-cyclodextrin derivatives and determine relationship between the structures and cytotoxicity. Three different methods were used, viability tests (MTT assay and Real Time Cell Electronic Sensing on Caco-2 cells) as well as hemolysis test on human red blood cells. The effect of α-cyclodextrin derivatives resulted in concentration-dependent cytotoxicity, so the IC50 values have been determined. Based on our evaluation, the Real Time Cell Electronic Sensing method is the most accurate for describing the time and concentration dependency of the observed toxic effects. Regarding the cytotoxicity on Caco-2 cells, phosphatidylcholine extraction may play a main role in the mechanism. Our results should provide help in selecting those α-cyclodextrin derivatives which have the potential of being used safely in medical formulations.

Abstract
OBJECTIVES The development of safe gene transfer carriers with high transfection efficiency, which does not affect the cell function, is a challenging issue. In this study, we examined the effects of α-cyclodextrin (α-CyD)/dendrimer conjugate (α-CDE (G3)) on nitric oxide (NO) production in murine macrophages J774.1 cells stimulated with toll-like receptors (TLR) ligands. METHODS NO production from macrophages stimulated with TLR ligands was determined by the Griess method. Transfection efficiency of α-CDE (G3)/plasmid DNA (pDNA) complex was quantified by a luminometer. KEY FINDINGS α-CDE (G3) significantly inhibited NO production from J774.1 cells stimulated with TLR ligands. α-CyD molecules in α-CDE (G3) had no effect on NO production. The inhibitory effect of α-CDE (G3) on NO production might be attributed to the dendrimer (G3). Increasing the degree of substitution (DS) of α-CyD in the α-CDE (G3) molecule was accompanied by a significant decrease in the inhibition of NO production. Furthermore, higher gene transfection efficiency of α-CDE (G3)/pDNA complex was observed upon increasing the DS of α-CyD. CONCLUSIONS α-CDE (G3) with high DS value of α-CyD may be considered as a safe gene transfer carrier that does not adversely affect NO production from macrophages stimulated with TLR ligands.

Abstract
Cyclodextrins have been extensively used in various biomedical and pharmaceutical applications. In these applications, cyclodextrins administered in vivo would inevitably enter blood stream. However, there is not enough information on the hemocompatibility of cyclodextrins until now. In this study, we investigated the influences of cyclodextrins (α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin) on human blood components and functions in vitro, that is, morphology and lysis of red blood cells, structure and conformation of fibrinogen, complement activation, and blood coagulation. It was found that 10 mg/mL of α- or β-cyclodextrins caused abnormal red blood cell morphology and serious hemolysis, while γ-cyclodextrin at 10 mg/mL did not impair red blood cell membrane morphology and integrity. The three cyclodextrins at up to 10 mg/mL affected the local microstructure but did not change the conformation of fibrinogen. The three cyclodextrins from 0.01 to 1 mg/mL all significantly activated the complement system in a concentration-dependent way. The three cyclodextrins at up to 5 mg/mL in blood plasma did not cause significantly different coagulation times compared with the negative control. In addition, the three cyclodextrins at up to 5 mg/mL in whole blood did not cause abnormal coagulation parameters. These results provide significant information on blood safety of the three cyclodextrins for their biomedical and pharmaceutical applications.

Abstract
OBJECTIVES GM1-gangliosidosis is an inherited disorder characterized by the accumulation of GM1-gangliosides in many tissues and organs, particularly in the brain. Currently, there is no treatment available for patients with ganglioside storage diseases. Therefore, we investigated the effects of cyclodextrins (CyDs) on the GM1-ganglioside level in EA1 cells, fibroblasts from patients with GM1-gangliosidosis. METHODS The concentrations of cholesterol and phospholipids in supernatants were determined by Cholesterol E-test Wako and Phospholipid C-test Wako, respectively. The effects of CyDs on GM1-ganglioside levels in EA1 cells using fluorescence-labelled cholera toxin B-subunit, which can bind to GM1-gangliosides specifically, were investigated by flow cytometry and confocal laser scanning microscopy. KEY FINDINGS The treatment with methylated CyDs, hydroxypropylated CyDs and branched CyDs decreased GM1-ganglioside levels in EA1 cells at 1 mm for 24 h. Unexpectedly, there was no significant change in the efflux of cholesterol or phospholipids from the cells after treatment with CyDs under the same experimental conditions, indicating that the efflux of membrane components is not associated with down-regulation of GM1-ganglioside levels in EA1 cells upon CyDs treatment. CONCLUSIONS CyDs may have the potential as drugs for GM1-gangliosidosis, although the mechanism should be thereafter clarified.

Abstract
Niemann-Pick type C (NPC) disease is characterized by the lysosomal accumulation of cholesterols and impaired autophagic flux due to the inhibited fusion of autophagosomes to lysosomes. We have recently developed β-cyclodextrin (β-CD)-threaded biocleavable polyrotaxanes (PRXs), which can release threaded β-CDs in response to intracellular environments as a therapeutic for NPC disease. The biocleavable PRXs exhibited effective cholesterol reduction ability and negligible toxic effect compared with hydroxypropyl-β-CD (HP-β-CD). In this study, we investigated the effect of biocleavable PRX and HP-β-CD on the impaired autophagy in NPC disease. The NPC patient-derived fibroblasts (NPC1 fibroblasts) showed an increase in the number of LC3-positive puncta compared with normal fibroblasts, even in the basal conditions; the HP-β-CD treatment markedly increased the number of LC3-positive puncta and the levels of p62 in NPC1 fibroblasts, indicating that autophagic flux was further perturbed. In sharp contrast, the biocleavable PRX reduced the number of LC3-positive puncta and the levels of p62 in NPC1 fibroblasts through an mTOR-independent mechanism. The mRFP-GFP-LC3 reporter gene expression experiments revealed that the biocleavable PRX facilitated the formation of autolysosomes to allow for autophagic protein degradation. Therefore, the β-CD-threaded biocleavable PRXs may be promising therapeutics for ameliorating not only cholesterol accumulation but also autophagy impairment in NPC disease.

Abstract
Background: Micelle formation of cholesterol with lecithin and bile salts is a key process for intestinal absorption of lipids. Some dietary fibers commonly used to reduce the lipid content in the body are thought to inhibit lipid absorption by binding to bile salts and decreasing the lipid solubility. Amongst these, α-cyclodextrin (α-CD) is reportedly one of the most powerful dietary fibers for decreasing blood cholesterol. However, it is difficult to believe that α-CD directly removes cholesterol because it has a very low affinity for cholesterol and its mechanism of action is less well understood than those of other dietary fibers. To identify this mechanism, we investigated the interaction of α-CD with lecithin and bile salts, which are essential components for the dissolution of cholesterol in the small intestine, and the effect of α-CD on micellar solubility of cholesterol. Results: α-CD was added to Fed-State Simulated Intestinal Fluid (FeSSIF), and precipitation of a white solid was observed. Analytical data showed that the precipitate was a lecithin and α-CD complex with a molar ratio of 1:4 or 1:5. The micellar solubility of cholesterol in the mixture of FeSSIF and α-CD was investigated, and found to decrease through lecithin precipitation caused by the addition of α-CD, in a dose-dependent manner. Furthermore, each of several other water-soluble dietary fibers was added to the FeSSIF, and no precipitate was generated. Conclusion: This study suggests that α-CD decreases the micellar solubility of cholesterol in the lumen of the small intestine via the precipitation of lecithin from bile salt micelles by complex formation with α-CD. It further indicates that the lecithin precipitation effect on the bile salt micelles by α-CD addition clearly differs from addition of other water-soluble dietary fibers. The decrease in micellar cholesterol solubility in the FeSSIF was the strongest with α-CD addition.

Abstract
Autophagy, the major lysosomal pathway for recycling intracellular components including organelles, is emerging as a key process regulating tumorigenesis and cancer therapy. Most recently, we newly synthesized folate-appended methyl-β-cyclodextrin (FA-M-β-CyD), and demonstrated the potential of FA-M-β-CyD as a new antitumor drug. In this study, we investigated whether anticancer activity of FA-M-β-CyD in folate receptor-α (FR-α)-positive tumor cells is involved in autophagy. In contrast to methyl-β-cyclodextrin (M-β-CyD), FA-M-β-CyD entered KB cells (FR-α (+)) through CLIC/GEEC endocytosis. No significant depression in the DNA content was observed in KB cells after treatment with FA-M-β-CyD. Additionally, the transmembrane potential of mitochondria after treatment with FA-M-β-CyD was drastically elevated. Meanwhile, FA-M-β-CyD induced the formation of autophagic vacuoles, which were partially colocalized with mitochondria, in KB cells. Taken together, these results suggest that FR-α-expressing cell-selective cytotoxic activity of FA-M-β-CyD could be mediated by the regulation of autophagy, rather than the induction of apoptosis.

Abstract
Methyl-β-cyclodextrin (MβCD) can be used to exchange membrane lipids between different vesicles in order to prepare model membrane vesicles with lipid asymmetry. To help define what factors influence lipid exchange, we studied how lipid interaction with cyclodextrins (CDs) was affected by lipid and CD structure. The decrease in light scattering upon CD-induced vesicle solubilization and the change in Förster resonance energy transfer of labeled lipids upon vesicle solubilization and lipid exchange were used to detect phospholipid-CD interaction. Of the CDs examined, MβCD, hydroxypropyl-α-cyclodextrin (HPαCD), and hydroxypropyl-β-cyclodextrin (HPβCD) were the three with the most suitable phospholipid interaction properties. Only MβCD was observed to dissolve lipid vesicles (at least at CD concentrations below 125 mM). Solubilization of lipid vesicles was half complete at 10-80 mM MβCD with progressively higher MβCD concentrations required as phospholipid acyl chain length increased from 14 to 22 carbons. Phospholipid acyl chain unsaturation and lipid headgroup structure also affected the amount of MβCD needed for solubilization. All three CDs studied were able to carry out phospholipid exchange. MβCD, which retained the ability to carry out lipid exchange below MβCD concentrations needed for solubilization, exchanged lipid more efficiently than HPαCD or HPβCD. However, the ability of HPαCD to exchange phospholipids, coupled with its inability to interact with cholesterol, indicates that it will be useful for preparing asymmetric vesicles with controlled amounts of cholesterol.

Abstract
Insulin resistance is due to the reduced cellular response to insulin in peripheral tissues. The interaction of insulin with its receptor is the first step in insulin action and thus the identified target of insulin resistance. It has been well established that defects or mutations in the insulin receptor (IR) cause insulin resistance. Therefore, an IR activator might be a novel therapeutic approach for insulin resistance. Our previous report showed that mild electrical stress (MES) enhanced the insulin-induced signaling pathway. However, the molecular mechanism of the effect of MES remains unclear. We assessed the effect of MES, which is characterized by low-intensity direct current, on insulin signaling in vitro and in vivo. Here, we showed that MES activated the insulin signaling in an insulin-independent manner and improved insulin resistance in peripheral tissues of high fat-fed mice. Moreover, we found that MES increased the localization of IR in lipid rafts and enhanced the level of phosphorylated Akt in insulin-resistant hepatic cells. Ablation of lipid rafts disrupted the effect of MES on Akt activation. Our findings indicate that MES has potential as an activator of IR in an insulin-independent manner, and might be beneficial for insulin resistance in type 2 diabetes.

Abstract
To obtain a tumor cell-selectivity of methyl-β-cyclodextrin (M-β-CyD), we newly synthesized folate-appended M-β-CyD (FA-M-β-CyD), and evaluated the potential of FA-M-β-CyD as a novel anticancer agent in vitro and in vivo. Potent antitumor activity and cellular association of FA-M-β-CyD were higher than those of M-β-CyD in KB cells, folate receptor (FR)-positive cells. FA-M-β-CyD drastically inhibited the tumor growth after intratumoral or intravenous injection to FR-positive Colon-26 cells-bearing mice. The antitumor activity of FA-M-β-CyD was comparable and superior to that of doxorubicin after both intratumoral and intravenous administrations, respectively, at the same dose, in the tumor-bearing mice. All of the tumor-bearing mice after an intravenous injection of FA-M-β-CyD survived for at least more than 140 days. Importantly, an intravenous administration of FA-M-β-CyD to tumor-bearing mice did not show any significant change in blood chemistry values. These results strongly suggest that FA-M-β-CyD has the potential as a novel anticancer agent.

Abstract
2-Hydroxybutyl-β-cyclodextrins (HB-β-CyDs) with different degrees of substitution (D.S.) were prepared and their physicochemical and biological properties and solubilizing abilities were studied and compared with those of 2-hydroxypropyl-β-cyclodextrin (HP-β-CyD). The surface activity of HB-β-CyD was higher than that of HP-β-CyD (D.S. 5.6) and increased with its concentration and D.S. The moisture sorption of HB-β-CyD (D.S. 5.5) was less than that of HP-β-CyD (D.S. 5.6), because of the introduction of hydrophobic hydroxybutyl groups in a molecule. The hemolytic activity (rabbit erythrocytes) decreased in the order of 2,6-di-O-methyl-β-cyclodextrin (DM-β-CyD)>methyl-β-cyclodextrin (M-β-CyD)>HB-β-CyD (D.S. 5.5)>β-CyD>HP-β-CyD (D.S. 5.6). The hemolytic activity of HB-β-CyD increased with D.S. and HB-β-CyD induced echinocyte (or crenation), as well as DM-β-CyD does. It was suggested from the solubility study of membrane components that HB-β-CyD interacted predominantly with cholesterol in erythrocytes, resulting in the hemolysis. The inclusion ability of HB-β-CyD was higher than that of HP-β-CyD (D.S. 5.6), especially for poorly water-soluble drugs with long linear structures such as biphenylylacetic acid and flurbiprofen (FP). For example, HB-β-CyD formed the inclusion complex with FP in a molar ratio of 1:1, by including the biphenyl moiety in the host cavity. The dissolution rate of FP/HB-β-CyD (D.S. 5.5) complex was faster than that of HP-β-CyD (D.S. 5.6) complex. The results suggested that HB-β-CyDs have considerable pharmaceutical potential and can work as a fast-dissolving carrier for poorly water-soluble drugs.

Abstract
We have demonstrated that protein kinase Cδ (PKCδ) could be involved in macrophage apoptosis induced by cationic liposomes composed of stearylamine (SA-liposomes), but the detailed mechanism of how SA-liposomes activate PKCδ has remained unclear. In this paper, we clarified whether lipid rafts are involved in the PKCδ activation induced by SA-liposomes. Co-localization of SA-liposomes and Cholera toxin B subunit (CBT), which specifically binds to ganglioside GM1 on lipid rafts, was found by microscopic observation. The incorporation of SA-liposomes into lipid rafts was clearly inhibited by the pretreatment of cells with an agent, 2,6-di-O-methyl-α-cyclodextrin (DM-α-CD) which disrupts lipid rafts. Activation of PKCδ and externalization of phosphatidylserine induced by SA-liposomes were also suppressed by DM-α-CD, which extracts sphingolipids and proteins from lipid rafts. Reactive oxygen species (ROS) generation, which could be involved in the macrophage apoptosis, was also inhibited by DM-α-CD. Furthermore, apoptosis induced by SA-liposomes was clearly inhibited when the cells were pre-treated with DM-α-CD, but not nystatin, a cholesterol-sequestering agent that disrupt lipid rafts. These findings suggest that sphingolipids in lipid rafts are involved in the activation of PKCδ which leads to apoptosis induced by cationic liposomes, SA-liposomes.

In Vitro Gene Delivery Mediated by Asialofetuin-Appended Cationic Liposomes Associated with γ-Cyclodextrin into Hepatocytes. JOURNAL OF DRUG DELIVERY 2010; 2011:476137.

Abstract
The purpose of this study is to evaluate in vitro gene delivery mediated by asialofetuin-appended cationic liposomes (AF-liposomes) associating cyclodextrins (CyD/AF-liposomes) as a hepatocyte-selective nonviral vector. Of various CyDs, AF-liposomes associated with plasmid DNA (pDNA) and γ-cyclodextrin (γ-CyD) (pDNA/γ-CyD/AF-liposomes) showed the highest gene transfer activity in HepG2 cells without any significant cytotoxicity. In addition, γ-CyD enhanced the encapsulation ratio of pDNA with AF-liposomes, and also increased gene transfer activity as the entrapment ratio of pDNA into AF-liposomes was increased. γ-CyD stabilized the liposomal membrane of AF-liposomes and inhibited the release of calcein from AF-liposomes. The stabilizing effect of γ-CyD may be, at least in part, involved in the enhancing gene transfer activity of pDNA/γ-CyD/AF-liposomes. Therefore, these results suggest the potential use of γ-CyD for an enhancer of transfection efficiency of AF-liposomes.

Abstract
Lipid rafts on cell membranes have heterogeneity such as cholesterol-rich microdomains and sphingolipids-rich microdomains. We previously reported that beta-cyclodextrin (beta-CyD) induced morphological changes of red blood cells (RBC) from discocyte to stomatocyte, possibly due to extraction of cholesterol from cholesterol-rich lipid rafts of RBC membranes. In this study, the effects of methyl-beta-cyclodextrin (M-beta-CyD) and 2,6-di-O-methyl-beta-cyclodextrin (DM-beta-CyD) on lipid rafts and morphological changes in rabbit RBC (RRBC) were examined, compared to those of beta-CyD. In sharp contrast to beta-CyD, M-beta-CyD and DM-beta-CyD induced morphological changes of RRBC from discocyte to echinocyte. At pre-hemolytic concentrations of beta-CyDs, M-beta-CyD and DM-beta-CyD strongly released cholesterol from cholesterol-rich lipid rafts, compared to beta-CyD. Meanwhile, the lowering effects of DM-beta-CyD on fluorescent sphingomyelin analogue in sphingolipids-rich lipid rafts were more potent than those of beta-CyD and M-beta-CyD. The magnitude of the abilities of M-beta-CyD and DM-beta-CyD to extract membrane constituents was higher than that of beta-CyD, consistent with that of hemolytic activity. Furthermore, DM-beta-CyD and M-beta-CyD, not beta-CyD, lowered the amount of proteins in cholesterol-rich lipid rafts of RRBC. These results suggest that higher hemolytic activity and morphological changes from discocyte to echinocyte in RRBC induced by M-beta-CyD and DM-beta-CyD may be due to the extraction of both cholesterol and proteins from cholesterol-rich lipid rafts of RRBC, although DM-beta-CyD may interact with sphingolipids-rich lipid rafts on RRBC membranes only slightly.

Abstract
In the present study, we examined the effects of alpha-cyclodextrin (alpha-CyD), 2-hydroxypropyl-alpha-cyclodextrin (HP-alpha-CyD) and 2,6-di-O-methyl-alpha-cyclodextrin (DM-alpha-CyD) on the nitric oxide (NO) and interferon-beta (IFN-beta) production in murine and human macrophages stimulated with Poly I:C and CpG-DNA, toll-like receptor 3 (TLR3) and TLR9 ligands, respectively. DM-alpha-CyD significantly inhibited NO production in RAW264.7 cells and U937 cells differentiated by phorbol myristate acetate (PMA), murine and human macrophage-like cell lines, respectively, stimulated with Poly I:C without cytotoxicity, but neither alpha-CyD nor HP-alpha-CyD did. Meanwhile, the three alpha-CyDs did not inhibit NO production in RAW264.7 cells stimulated with CpG-DNA. DM-alpha-CyD inhibited inducible NO synthase (iNOS) and IFN-beta expression upon stimulation with Poly I:C. Furthermore, DM-alpha-CyD markedly decreased the cellular uptake of Poly I:C in RAW264.7 cells. Therefore, DM-alpha-CyD may be useful as a potent inhibitor for excess activation of macrophages stimulated with Poly I:C.
