Abstract
In this work, the hydroxypropyl-β-cyclodextrin (HP-β-CD)/Epicatechin (EC) clathrate compounds were rapidly prepared based on an ultrasound-mediated method, and Polycaprolactone (PCL)/Locust bean gum (LBG) nanofibers loaded clathrate compounds were fabricated by electrostatic spinning (ELS) for fruit packaging. The results of infrared spectrum and crystal type analysis proved that clathrate compounds were successfully prepared. With the addition of clathrate compounds, the diameter of fibers increased from 553.43 to 1273.47 nm, and hydrogen bonds were formed between clathrate compounds and fibrous membranes, which improved the thermal stability, reduced the crystallinity, and enhanced the hydrophilicity and gas permeability of fibrous membranes. The fibrous membranes indicated sustained release of EC for 240 h, retaining the activity of EC and demonstrating good bacteriostatic ability in vitro and in vivo. The test results showed that the antibacterial fibrous membranes prepared in this work have a positive application prospect for fruit packaging.

Abstract
Silymarin (SM) exhibits clinical efficacy in treating liver injuries, cirrhosis, and chronic hepatitis. However, its limited water solubility and low bioavailability hinder its therapeutic potential. The primary objective of this study was to compare the in vitro and in vivo characteristics of the four distinct SM solubilization systems, namely SM solid dispersion (SM-SD), SM phospholipid complex (SM-PC), SM sulfobutyl ether-β-cyclodextrin inclusion complex (SM-SBE-β-CDIC) and SM self-microemulsifying drug delivery system (SM-SMEDDS) to provide further insights into their potential for enhancing the solubility and bioavailability of SM. The formation of SM-SD, SM-PC, and SM-SBE-β-CDIC was thoroughly characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and powder X-ray diffractometry (PXRD) techniques to analyze the changes in their microscopic structure, molecular structure, and crystalline state. The particle size and polydispersity index (PDI) of SM-SMEDDS were 71.6 ± 1.57 nm, and 0.13 ± 0.03, respectively. The self-emulsifying time of SM-SMEDDS was 3.0 ± 0.3 min. SM-SMEDDS exhibited an improved in vitro dissolution rate and demonstrated the highest relative bioavailability compared to pure SM, SM-SD, SM-PC, SM-SBE-β-CDIC, and Legalon®. Consequently, SMEDDS shows promise as a drug delivery system for orally administered SM, offering enhanced solubility and bioavailability.

Molecules 2024; 29:2164. [PMID: 38792026 PMCID: PMC11124191 DOI: 10.3390/molecules29102164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 04/28/2024] [Accepted: 04/29/2024] [Indexed: 05/26/2024] Open
Abstract
Ethanamizuril (EZL) is a new anticoccidial drug developed by our Shanghai Veterinary Research Institute. Since EZL is almost insoluble in water, we conducted a study to improve the solubility of EZL by forming inclusion complexes with β-cyclodextrin (β-CD) and hydroxypropyl-β-cyclodextrin (HP-β-CD). In this study, we performed molecular docking and then systematically compared the interactions of EZL with β-CD and HP-β-CD in both aqueous solution and the solid state, aiming to elucidate the solubilization effect and mechanism of cyclodextrins (CDs). The interactions were also examined in the solid state using DSC, PXRD, and FT-IR. The interactions of EZL with CDs in an aqueous solution were investigated using PSA, UV-vis spectroscopy, MS, 1H NMR, and 2D ROESY. The results of phase solubility experiments revealed that both β-CD and HP-β-CD formed inclusion complexes with EZL in a 1:1 molar ratio. Among them, HP-β-CD exhibited higher Kf (stability constant) and CE (complexation efficiency) values as well as a stronger solubilization effect. Furthermore, the two cyclodextrins were found to interact with EZL in a similar manner. The results of our FT-IR and 2D ROESY experiments are in agreement with the theoretical results derived from molecular simulations. These results indicated that intermolecular hydrogen bonds existing between the C=O group on the triazine ring of EZL and the O-H group of CDs, as well as the hydrophobic interactions between the hydrogen on the benzene ring of EZL and the hydrogen of CDs, played crucial roles in the formation of EZL/CD inclusion complexes. The results of this study can lay the foundation for the future development of high-concentration drinking water delivery formulations for EZL.

Abstract
Although identical in molecular formula and weight, curcumin and cyclocurcumin show remarkable differences in their reactivity. Both are natural compounds isolated from the rhizome of turmeric, the former is involved in the diketo/keto-enol tautomerism through the bis-α,β-unsaturated diketone unit according to the polarity of the solvent, while the latter could react by trans-cis isomerization due to the presence of the α,β-unsaturated dihydropyranone moiety. Even if curcumin is generally considered responsible of the therapeutical properties of Curcuma longa L. due to its high content, cyclocurcumin has attracted great interest over the last several decades for its individual behavior and specific features as a bioactive compound. Cyclocurcumin has a hydrophobic nature characterized by fluorescence emission, solvatochromism, and the tendency to form spherical fluorescent aggregates in aqueous solution. Molecular docking analysis reveals the potentiality of cyclocurcumin as antioxidant, enzyme inhibitor, and antiviral agent. Promising biological activities are observed especially in the treatment of degenerative and cardiovascular diseases. Despite the versatility emerging from the data reported herein, the use of cyclocurcumin seems to remain limited in clinical applications mainly because of its low solubility and bioavailability.

Abstract
This study aimed to compare differences in interactions between cholesterol and β- cyclodextrin and its derivatives for selecting a suitable β-cyclodextrin derivative to efficiently remove cholesterol from high-melting-point foods. First, the formation of cholesterol/β-cyclodextrin derivative complexes was investigated using Fourier transform infrared spectroscopy and thermogravimetric analysis. Secondly, the conformations of β-cyclodextrin derivatives were determined from experimental and calculated 1H NMR spectra, and the weak interactions between cholesterol and β-cyclodextrin derivatives were studied by computational approach. Cholesterol/hydroxypropyl-β-cyclodextrin complex had the lowest complexation energy. Besides, two moderate hydrogen bonds were formed between cholesterol and hydroxypropyl-β-cyclodextrin and between cholesterol and sulfobutyl ether-β-cyclodextrin, while one weak hydrogen bond was formed between cholesterol and methyl-β-cyclodextrin. Finally, the efficiency of cholesterol removal by hydroxypropyl-β-cyclodextrin was 5.47% higher than that by β-cyclodextrin at their optimal temperature. This work provided a theoretical basis for selecting a competent adsorbent to effectively remove cholesterol from high-melting-point foods.

Abstract
Chitosan (CS) is becoming increasingly popular in food packaging due to its natural degradability and great film-forming properties. Nevertheless, its poor antibacterial properties and inadequate antioxidant properties prevent it from being used effectively. In this study, β-cyclodextrin-epichlorohydrin (β-CD-EP) oligomers were prepared and encapsulated with natural essential oils cinnamaldehyde and thymol, and then the inclusion complexes (IC) were incorporated into chitosan in various contents to afford a series of CS-IC composite films. The impacts of IC on the morphological, mechanical, thermal, and water resistance properties, antioxidant and antibacterial activities of chitosan films, as well as the loading and sustained release behavior of IC, were thoroughly examined. The results turned out that the essential oils were well-loaded with high encapsulation efficiency and showed a significant slow-release effect. It was also found that the tensile strength and the elongation at break decreased with increasing IC contents, while the thermal stability was enhanced. The incorporation of IC dramatically promoted the antioxidant and antibacterial properties of the chitosan films towards Gram-positive bacteria. Based on our findings, chitosan films containing essential oils-loaded β-CD-EP oligomers may serve as an effective food packaging material.

Abstract
OBJECTIVE The aim of the current research was the development hard cellulose capsules containing cefpodoxime proxetil (CEF) (BCS-Class II) encapsulated nanospheres of inclusion complexes with β-CD, HP-β-CD and M-β-CD for efficient antibacterial therapy. SIGNIFICANCE The reason for this phenomenon is to bring an innovative approach to effective oral antimicrobial therapy with hard cellulose capsules containing spray dried nanospheres of CEF with β-CD, HP-β-CD and M-β-CD by means of increased solubility, dissolution rate and improved antibacterial efficiency with lower oral dose. METHODS Phase solubility analyses was performed to evaluate the drug/CD interaction, involving the stoichiometry and apparent stability constant. Following the preparation of inclusion complexes by spray-drying method, complexes were characterized for physical, solid-state and microbiological analyses. In vitro dissolution from hard cellulose capsules containing CEF and CEF/β-CD, CEF/HP-β-CD and CEF/M-β-CD complexes were performed. RESULTS According to AL type phase solubility curves, complexes were formulated as 1:1 molar ratio. The solubility of pure CEF was determined as 0.241 ± 0.002 mg mL-1, the solubility of inclusion complexes increased solubility from 3 to 5 times. The strong host-guest interaction was confirmed for CEF/HP-β-CD and CEF/M-β-CD complexes with SEM, DSC, FT-IR and 1H-NMR analyses. Inclusion complexes were more efficient on bacterial cells (2-4 fold) than pure CEF both Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae. Hard-cellulose capsules filled with inclusion complexes exhibited significantly faster release than unprocessed CEF. CONCLUSION Hard-cellulose capsules containing CEF/HP-β-CD and CEF/M-β-CD complexes appear to be superior alternative to commercially available CEF tablets for effective antibacterial therapy.

Abstract
The formation of inclusion complexes between triamterene (TT) and cyclodextrins (CDs) to increase the water apparent solubility of TT was investigated. UV data showed that the binding constant of the TT/sulfobutylether-β-cyclodextrin (SBE-β-CD) inclusion complex was 510 L/mol. The phenyl ring of TT was inserted into the secondary hydroxy face of SBE-β-CD, as demonstrated by 1H-1H rotating frame nuclear Overhauser effect spectroscopy NMR. Physicochemical properties of solid TT/SBE-β-CD complexes prepared by physical mixing, kneading, freeze-drying, and mechanochemical methods were studied by X-ray diffraction and 13C cross-polarization and magic angle spinning NMR. With the mechanochemical method, the diffraction peak corresponding to TT disappeared, indicating the formation of an inclusion complex. The results of the dissolution test revealed that the solid complex obtained by the mechanochemical method improved the dissolution of TT. The water apparent solubility of TT can be improved by simple mechanical mixing without organic solvents, and improved bioavailability after oral administration is expected.

Abstract
In this study, umbelliferone and α-cyclodextrin host molecules have been mixed up through a coprecipitation method to prepare a supramolecular complex to provide physical insights into the formation and stability of the inclusion complex (IC). The prepared hybrid was characterized by 1H nuclear magnetic resonance (1H NMR), Fourier transform infrared (FTIR) spectroscopy, electrospray ionization (ESI) mass spectrometry, DSC, and fluorescence spectroscopic studies. Job's plot provides a stoichiometric ratio of 1:1 and the Benesi-Hildebrand double reciprocal plot gives binding constant values using fluorescence spectroscopic titrations and the ESI mass data support the experimental observations. The results of molecular modeling were systematically analyzed to validate the inclusion complexation. In preliminary computational screening, α-cyclodextrin IC of umbelliferone was found to be quite stable based on the docking score, binding free energies, and dynamic simulations. In addition, the results obtained from 1H NMR and FTIR spectroscopy studies supported the inclusion complexation phenomenon. The results obtained from computational studies were found to be consistent with the experimental data to ascertain the encapsulation of umbelliferone into α-cyclodextrin.

Abstract
Asiaticoside (AS) is poorly water-soluble compound that can lead to low the bioavailability. The aims of this study were to determine the cyclodextrin (CD) solubilization of AS and characterize binary AS/CD and ternary AS/CD/polymer complexes in solution- and solid-state. Thermal stability of AS through heating process was determined and found that It could withstand by heating through sonication method. Phase-solubility profiles showed that β-cyclodextrin (βCD) exhibited the greatest solubilizing effect but sulfobutylether-βCD (SBEβCD) was selected for further investigations due to its relatively high complexation efficiency (CE) value. The effect of polymers that were poloxamer 407 (P407) and chitosan (CS) on CD solubilization were investigated. It was found that the increment of CE was resulted from the formation of ternary complexes or complex aggregates with confirmed by dynamic light scattering and transmission electron microscopy. Proton nuclear magnetic resonance (1H NMR) data indicated that the cyclohexane moiety of AS was totally inserted into the hydrophobic inner cavity of SBEβCD in the presence or absence of polymer. The molecular modeling study displayed the binding orientation of such complex which correlated to 1H NMR result. The solid state characterized by Fourier transform infra-red, differential scanning calorimetry and powder X-ray diffraction demonstrated the formation of binary AS/SBEβCD and ternary AS/SBEβCD/polymer inclusion complexes. The enhancement of AS dissolution was achieved in both binary and ternary complexes. The permeation study showed that ternary AS/SBEβCD/CS nanoparticles exhibited a promising controlled drug release nanocarrier.

Abstract
In this study, a novel cyclodextrin derivative, i.e., zwitterionic choline phosphate (CP)-functionalized β-cyclodextrin (CP-β-CD) is successfully synthesized by click chemistry reaction. CP-β-CD has excellent cell-membrane-targeted ability because of the CP group can bind to phosphate choline (PC) in the cell membrane and promote the cellular uptake. Due to the introduction of CP group on β-CD, it disrupts the hydrogen network between natural β-CD molecules. Meanwhile, the water solubility of CP-β-CD is improved dramatically to 816 mg mL-1 , which is 440 times as that of unmodified β-CD. Apatinib, a small molecular inhibitor, is used as a model of hydrophobic drug and loaded into CP-β-CD to study the solubilization effect and the anti-angiogenisis activity. In addition, the cytotoxicity of CP-β-CD is also studied, and it is demonstrated that CP-β-CD is nontoxic. These results indicate that the apatinib can be transported into cell interior and play an excellent anti-angiogenisis activity after being loaded into CP-β-CD drug delivery system. This work suggests that the water soluble CP-β-CD with excellent cell internalization efficiency has a potential application prospect in the field of drug delivery.

Abstract
A natural hydrogel film was prepared using carboxymethyl cellulose (CMC), cellulose nanocrystals (CNC), and hydroxypropyl β cyclodextrin (HP-β-CD) as reactants and citric acid as the cross-linking agent and used for the controlled release of neohesperidin-copper(II)(NH-Cu (II)). The hydrogel film was characterized by ATR-FTIR, XRD, TGA and DSC. The film showed controlled swelling behavior; the release behavior of NH-Cu(II) from the hydrogel film was also investigated in different solutions including distilled water, various salt solutions including 0.9% NaCl, and solutions having different pH values. Thiazolyl blue tetrazolium bromide assay and relative growth rates were adopted to evaluate the biocompatibility and cytotoxicity of the prepared hydrogel films. The results indicated that the expansion kinetics followed Fickian diffusion and Schott's second-order kinetics model. The hydrogel film exhibited enhanced mechanical properties and improved thermal stability at high temperatures due to the addition of CNC, with the amount of added CNC affecting the swelling ratio, salt sensitivity, and pH sensitivity of the hydrogel film in different solutions. Additionally, the CNC largely improved the loading and encapsulation efficiency of the hydrogel films, with the optimal CNC addition amount being 4% which yielded a loading amount of 753.75 mg/g and an accumulated release rate of 85.08%. The hydrogel film with proven cell compatibility and non-cytotoxicity can potentially be used as a drug delivery and controlled release material.

Abstract
The stability of azithromycin in buffered aqueous solution at pH 6.7 was investigated in the presence of different cyclodextrin (CD) additives by HPLC monitoring of the drug concentration over time. In the presence of γ-CDs, either in native or derivatized form, the long-term stability of azithromycin was sensibly decreased with respect to the reference sample without any additives, whereas the opposite effect was observed with all the three tested β-CDs. The most effective stabilization of the drug was obtained by using sulfobutyl ether-β-cyclodextrin, which allowed a concentration of azithromycin in solution at 99% up to 6 months at room temperature. The positive action of sulfobutyl ether-β-cyclodextrin was mainly exerted through the suppression of a degradation pathway leading to the opening of lactone ring of azithromycin. The formation of dynamic inclusion complexes in solution was ruled out by NMR data and stabilization of azithromycin by the amphiphilic sulfobutyl ether-β-cyclodextrin through surfactant-like effects was proposed on the basis of the strict similarity, either in the degradation profiles and in the NMR data, with a solution of the drug in the presence of sodium hexylsulphonate as surfactant.

Abstract
Cyclodextrin (CD) inclusions are generally used to increase the solubility of poorly soluble drugs. In this study, magnolol (MAG) was used as a model drug for exploring the effects of CD on the degradation of pharmaceutical drugs by intestinal microflora. MAG/β-cyclodextrin (β-CD) and MAG/hydroxypropyl-β-CD (HP-β-CD) inclusion complexes were successfully prepared by the saturated aqueous solution and freeze-drying methods, respectively. Structural characterisation along with analyses of solubility, residual water content and drug content of the inclusion complexes was performed. The intestinal microflora of male rats was used to study MAG degradation in vitro. At three concentrations, the degradation of both the inclusion complexes was slower than that of the MAG monomer, MAG and CD mixtures and the MAG-poloxamer 188 micelle. There were no statistically significant differences in the degradation of the MAG/β-CD and MAG/HP-β-CD inclusion complexes. A simulation first-order equation of the degradation parameters revealed that the degradation of the inclusion complexes was slower and pronounced, judging by slope. The experimental findings were verified by molecular docking for predicting the stable molecular structure of the inclusion complexes. In conclusion, the inclusion complexes partially protected MAG from degradation by the intestinal bacteria.

Abstract
A new adamantane-based ionic liquid, (11-(((-adamantane-1-carbonyl)oxy)undecyl)-1-methylimidazol-3-ium bromide (AD-C11im), was synthesized from 1-adamantanecarboxylic acid and observed that it can aggregate into micelles in aqueous solution. A number of experiments were conducted to understand the self-assembly of supra-amphiphiles building block fabricated by β-cyclodextrin (β-CD) and adamantane-based ionic liquid at diverse molar ratios. Studies revealed that host–guest interaction between the adamantane group and β-CD occurred and AD-C11im@1β-CD building block formed when same amount β-CD was added. Then the micelles aggregates formed by AD-C11im only turned into spherical vesicles, which was confirmed by AFM, DLS and TEM. Besides, according to the results of AFM, it can be confirmed that the vesicles were monolayer structure. When double amount β-CD was added, both the adamantane group and the hydrophobic chain were encapsulated by β-CD and AD-C11im@2β-CD building block formed. Thus the aggregations changed from vesicles to net-like nanofiber, which was observed by TEM. When the β-CD concentration increased to 40 mM, the formation of light blue hydrogel was observed during the self-assembling process of AD-C11im@2β-CD building block. The self-assembly of supra-amphiphiles building block fabricated by β-CD and AD-C11im at diverse molar ratios was studied. The micelles of AD-C11im turned into monolayer vesicles, net-like nanofibers and hydrogel at different β-CD/AD-C11im system.![]()

Abstract
Fucoxanthin is a major marine carotenoid with many biological activities. It is well known that fucoxanthin is unstable to heat and acid due to its polyunsaturated structure. Another defect of fucoxanthin is the low bioavailability and all these drawbacks make it limited in the food industry. In order to improve its stability and intestinal absorption, fucoxanthin was encapsulated with biopolymers by spray drying in this study. All the microspheres we prepared had a spherical shape with encapsulation efficiencies (EE) ranging from 86.48% to 97.06%. A heat stability test showed that maltodextrin (MD), gum arabic (GA) and whey protein isolate (WPI) improved the thermal stability of fucoxanthin. The degradation kinetics of the loaded fucoxanthin encapsulated with biopolymers also indicated that GA and MD had a better protective effect on fucoxanthin. The encapsulated fucoxanthin degradation rate within MD, GA, WPI and gelatin (GEL) followed second-order kinetics and their half-life (t 1/2) was 92.6 d, 99.8 d, 50.9 d and 69.3 d, respectively. The simulated digestion test in vitro suggested that MD, GA and WPI effectively protected fucoxanthin in the gastric acid environment, meanwhile increasing the release rate of fucoxanthin in the intestinal tract.

Abstract
Spiral dextrin subfraction (SD-40) obtained through enzyme debranching and gradient ethanol precipitation could interact with vitamin E (VE) or soy isoflavone (SIO) to form V-type inclusion complexes. The formation of two inclusion complexes was confirmed by Fourier transform-infrared spectroscopy, atomic force microscopy, and differential scanning calorimetry. In this study, an in vitro gastrointestinal model was used to investigate the breakdown of inclusion complexes and release behavior of bioactive compounds. The results indicated that the two inclusion complexes exhibited a controlled and sustained release behavior during digestion. In addition, the SD-40/VE inclusion complex presented higher stability and stronger antioxidant capacity than the SD-40/SIO inclusion complex. Furthermore, the first and zero order models were applied to understand the release kinetics of VE and SIO from inclusion complexes in the stomach, whereas the first order model was chosen to describe the release of VE and SIO from inclusion complexes in the intestine.

Abstract
The aim of this study was to determine the degradation of dietary isoflavones in rumen fluid under 2 feeding regimens. The experiments were performed in vitro using a rumen fluid buffer system. The rumen fluid was taken from cows fed either a hay diet or a concentrate-rich diet (the diet consisted of 34.6% maize silage, 17.6% haylage, 12.8% alfalfa hay, and 35.0% supplemental mixture on a dry matter basis). As a source of isoflavones, 40% soybean extract (Biomedica, Prague, Czech Republic) at levels of 5, 25, 50, and 75 mg per 40 mL of rumen fluid was used. Samples of soybean extract were incubated in triplicate at 39°C for 0, 3.0, 6.0, 12.0, and 24.0 h in incubation solution. The metabolism of daidzein and genistein was faster under concentrate-rich diet conditions. In general, production of equol started after 3 to 6 h of incubation and reached the highest rate after approximately 12 h of incubation regardless of the type of diet or concentration of extract. In most of the experiments, production of equol continued after 24 h of incubation. Generally, equol production was greater under the hay diet conditions. Furthermore, experiments with higher amounts of added soybean extract revealed possible inhibitory effects of high levels of isoflavones on the rumen microflora.

Abstract
This work aimed to investigate the potential effect of cyclodextrin encapsulation on intrinsic ability of daidzein (DAD) and genistein (GEN) to inhibit the glycosaminoglycan (GAG) synthesis in fibroblasts originating from patients with mucopolysaccharidosis (MPS), type II and III. DAD or GEN encapsulation with either 2-hydroxypropyl-β-cyclodextrin or sulphobuthylether-β-cyclodextrin were achieved by neat grinding and were characterised by thermal analysis, X-ray powder diffraction, scanning electron microscopy and solubility testing which confirmed the complexes formation with increased solubility with respect to starting compounds. Both isoflavones, as well as their co-ground cyclodextrin complexes reduced GAG levels in the fibroblasts of MPS II and MPS III patients from 54.8-77.5%, in a dose dependent manner, without any significant cytotoxic effect. Cyclodextrin encapsulation did not change the intrinsically high effect of both DAD and GEN on the GAG level reduction in the treated cells, thus could be considered as a part of combination therapies of MPS.
