Abstract
Biologically important macromolecule 1, 1', 3, 3' Bis - [2,3,5,6-Tetramethyl-p-phenylenebis(methylene)] dibenzotriazlinium dibromide hydrate (BTD) was synthesized and characterized using FT-IR, NMR and single-crystal XRD (SCXRD). SCXRD revealed that the compound was crystallized as a monoclinic system and associated through weak intermolecular interactions like H-bonding and π- π stacking interactions. These weak intermolecular interactions in BTD were studied using Crystal Explorer and Gaussian. The calculated energies for the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO) showed the stability and reactivity of the title compound. Molecular electrostatic potential (MEP) surface analysis was used to investigate the crystal's nucleophilic and electrophilic reactive sites. The molecular shape and intermolecular interactions in the crystal structure were determined using Hirshfeld surface analysis and fingerprint plots. Anticancer, anti-bacterial and DNA binding ability of BTD were investigated by experimental and theoretical techniques. The obtained results suggest that BTD possesses better anti-cancer, anti-bacterial and DNA binding abilities. The mode of action of antibiotic and anticancer approach was discussed. This provides promising therapeutic advantages for further development.

Abstract
Homeostatic technologies play a crucial role in maintaining the quality and extending the service life of aroma compounds (ACs). Commercial cyclodextrins (CDs) are commonly used to form inclusion complexes (ICs) with ACs to enhance their solubility, stability, and morphology. The selection of suitable CDs and ACs is of paramount importance in this process. Molecular dynamics (MD) simulations provide an in-depth understanding of the interactions between ACs and CDs, aiding researchers in optimising the properties and effects of ICs. This review offers a systematic discussion of the application of MD simulations in ACs/CDs ICs, covering the establishment of the simulation process, parameter selection, model evaluation, and various application cases, along with their advantages and disadvantages. Additionally, this review summarises the major achievements and challenges of this method while identifying areas that require further exploration. These findings may contribute to a comprehensive understanding of the formation and stabilization mechanisms of ACs/CDs ICs and offer guidance for the selection and computational characterisation of CDs in the AC steady state.

Host-guest inclusion complexes of hydroxytyrosol with cyclodextrins: Development of a potential functional ingredient for food application. J Food Sci 2022; 87:2678-2691. [PMID: 35534089 DOI: 10.1111/1750-3841.16165] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 03/31/2022] [Accepted: 04/07/2022] [Indexed: 12/11/2022]
Abstract
Hydroxytyrosol (HT), a potent phenolic phytochemical, exerts positive health effects due to its antioxidant properties. However, it is highly reactive to oxygen, light, and heat and presents high instability. Alpha- and beta-cyclodextrin (α-CD, β-CD) have structures that allow them to encapsulate a variety of hydrophobic molecules. The aim of this study was to examine the outcomes of the inclusion of HT into α-CD and β-CD. Aqueous solutions of HT and either α-CD or β-CD were prepared and freeze-drying was applied for the encapsulation, in 1:1 and 2:1 molar ratios. The produced solid complexes were studied and characterized using NMR spectroscopy, differential scanning calorimetry (DSC) and attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR). Encapsulation efficiency (EE%), stability, and in vitro release of the encapsulated complexes under simulated digestion conditions were also evaluated. In both DSC thermograms and FTIR spectra of the inclusion complexes, absence of the characteristic peaks of HT and shifts of the CDs peaks were observed, showing an interaction between the molecules. NMR suggested a stronger complex formed between β-CD and HT. The EE% of β-CD/HT (1:1 and 2:1) complexes and α-CD/HT (1:1) complex was found to be higher (83%, 76%, 78%, respectively), compared to α-CD/HT (2:1) (51%). Data obtained support the encapsulation of HT in both CDs, revealing a potential interaction between them and an improvement in HT's thermal stability. Regarding the in vitro release study, both CD complexes had similar behavior and a controlled release of HT in the intestinal site was observed. PRACTICAL APPLICATION: The encapsulation of hydroxytyrosol in cyclodextrins resulted in white amorphous food-grade powders with no aroma and taste. Incorporation of these powders in foods could lead to an increase in their antioxidant content and offer an additional nutritional value.

Abstract
In this work, novel photoluminescent Ag nanoclusters (Ag NCs) with red emission are synthesized and successfully used for detecting iodide ion (I-). The dihydrolipoic acid (DHLA) is used as the stabilizing agent and beta-cyclodextrin (β-CD) is used as the auxiliary stabilizing agent. DHLA and β-CD are combined with Ag atoms by the formation of AgS bonds and hydrophobic interaction, respectively. Functionalization of β-CD endows good photoluminescent properties and solubility in water to the Ag NCs. The obtained DHLA and β-CD-protected Ag NCs (DHLA/β-CD-Ag NCs) are spherical and display a dispersed state. However, the DHLA/β-CD-Ag NCs are aggregated in the presence of I-, accompanied by the decrease in their fluorescence intensity. Because the integrity of β-CD cavities is retained on the surface of DHLA/β-CD-Ag NCs, which preserves their capability for I- host-guest recognition, the DHLA/β-CD-Ag NCs combine with I- through the formation of inclusion complexes. Based on this phenomenon, the prepared DHLA/β-CD-Ag NCs can be designed as a novel fluorescent probe for I- detection. The limit of detection (LOD) is calculated as 0.06 μM, indicating that it is an ideal probe for I- detection in practical applications.

Abstract
Self assembly of α-cyclodextrin (α-CD) and β-cyclodextrin (β-CD) micro rods induced by omeprazole (OMP) were observed by SEM and TEM. OMP/CD inclusion complexes have formed the secondary self assembly micro meter size rod like structure. This structure was driven by the intermolecular hydrogen bonding as well as van der Waals forces. Both forces induced the ordered assembly and arrangement of OMP/CD inclusion complexes, whereas CD molecules acted as molecular bricks. The OMP/CD inclusion complexes primary assembled form individual nanorods and then secondary self aggregate nanorods were form a micro meter rod structure. The results indicate that inter-nanotubular hydrogen bonding plays a crucial role in the formation of the self assembled micro rods. The inclusion complexes were also characterized using FT-IR, DSC, powder XRD, (1)H NMR, absorption, fluorescence, life time measurements and molecular modeling methods.

Abstract
Inclusion complexation behavior of procainamide (PCA) with two cyclodextrins (α-CD and β-CD) were analyzed by absorption, fluorescence, scanning electron microscope (SEM), transmission electron microscope (TEM), Raman image, FT-IR, differential scanning colorimeter (DSC), Powder X ray diffraction (XRD) and (1)H NMR. Blue shift was observed in β-CD whereas no significant spectral shift observed in α-CD. The inclusion complex formation results suggest that water molecules also present in the inside of the CD cavity. The present study revealed that the phenyl ring of the PCA drug is entrapped in the CD cavity. Cyclodextrin studies show that PCA forms 1:2 inclusion complex with α-CD and β-CD. PCA:α-CD complex form nano-sized particles (46 nm) and PCA:β-CD complex form self-assembled to micro-sized tubular structures. The shape-shifting of 2D nanosheets into 1D microtubes by simple rolling mechanism were analysed by micro-Raman and TEM images. Thermodynamic parameters (ΔH, ΔG and ΔS) of inclusion process were determined from semiempirical PM3 calculations.

Abstract
Inclusion complex formation of 4-hydroxy-3-methoxybenzoic acid (HMBA) and 4-hydroxy-3,5-dimethoxybenzoic acid (HDMBA) with α-CD, β-CD, HP-α-CD and HP-β-CD were studied by absorption, steady state fluorescence, time resolved fluorescence, FT-IR, (1)H NMR and molecular modeling methods. The effect of the CDs with HMBA and HDMBA were studied in pH∼1, pH∼7 and pH∼10 buffer solutions. The study revealed that both hydroxybenzoic acids formed 1:1 complex with the four CDs. The theoretical values suggest that both guests are partially encapsulated into the CDs cavity. The hydroxy group is present in the interior part of the CD cavity and carboxyl group is present in the hydrophilic part of the CD cavity. Molecular modeling studies proved that (i) the negative Gibbs energy and enthalpy changes for the inclusion complexes indicated that the formation of these complexes were spontaneous and exothermic, (ii) hydrogen bonding interactions played a major role in the inclusion process, (iii) the dipole moment values for guests increased when they entered into the CDs cavities which is an indication of the increase of the polarity and the formation of complex and (iv) differences in binding energy and enthalpy change suggest that the β-CD formed more stable complex than α-CD.

Abstract
Inclusion complex formation of two local anesthetics drugs (lidocaine (LC) and prilocaine (PC)) with α- and β-cyclodextrins (CDs) in aqueous solution were studied by absorption, fluorescence, time-resolved fluorescence and molecular modeling methods. The formation of inclusion complexes was confirmed by 1H NMR, FTIR, differential scanning calorimetry, SEM, TEM and X-ray diffractometry. Both drugs formed 1:1 inclusion complex and exhibit biexponential decay in water whereas triexponential decay in the CD solution. Nanosized self-aggregated particles of drug: CD complexes were found by TEM. Both experimental and theoretical studies revealed that the phenyl ring with the amide group of the drug is encapsulated in the hydrophobic CD nanocavity. Investigations of energetic and thermodynamic properties confirmed the stability of the inclusion complexes. van der Waals interactions are mainly responsible for enthalpy driven complex formation of LC and PC with CDs.

Abstract
Sulfadiazine (SDA) and sulfisomidine (SFM) inclusion complexes with two cyclodextrins (α-CD and β-CD) are studied in aqueous as well as in solid state. The inclusion complexes are characterized by UV-visible, fluorescence, time correlated single photon counting, FTIR, DSC, PXRD and (1)H NMR techniques. The self assembled SDA/CD and SFM/CD inclusion complexes form different types of nano and microstructures. The self assembled nanoparticle morphologies are studied using SEM and TEM techniques. SDA/α-CD complex is formed hierarchal morphology, SDA/β-CD and SFM/β-CD complexes form the nanosheet self assembly. However, SFM/α-CD complex forms nanoporous sheet self assembly. van der Waals, hydrophobic and hydrogen bonding interaction play a vital role in the self assembling process.

Abstract
Cyclodextrin (α and β) based nanostructures formed with 2-aminobenzophenone, 3-aminobenzophenone through the supramolecular self assembly are studied by absorption, fluorescence, time-resolved fluorescence, SEM, TEM, FT-IR, DSC, PXRD and (1)H NMR. The unequal layer by layer nanosheets and nanoribbons are formed through self assembly of 3ABP/CD inclusion complexes. 2ABP/α-CD complex nanostructures show the self assembly hierarchical thread structure and β-CD complexes displays a nanobrick structure. The formation of nanostructures are prearranged to HO⋯H, NH2⋯O and H2N⋯H intermolecular hydrogen bond between individual complexes. The absorption and fluorescence spectral changes explicit formation of 1:1 inclusion complexes and solvent study demonstrate the ESIPT and TICT present in both molecules. The thermodynamic parameters (ΔH, ΔG and ΔS) of 2ABP and 3ABP molecule and the inclusion complexes were determined from semiempirical PM3 calculations.

Abstract
Inclusion complexation behavior and binding ability of sulfamerazine (SMRZ) with α- and β-cyclodextrins (α-CD and β-CD) were investigated. The formation of inclusion complexes are studied by UV-visible, fluorescence, time-resolved fluorescence, (1)H NMR, FT-IR, DSC, XRD, SEM, TEM and molecular modeling methods. Both experimental and PM3 results indicated that the SMRZ is partially encapsulated in the CD cavity. The different spectral shifts observed in both the CDs indicate that different types of inclusion complexes are formed. Nanosecond time-resolved fluorescence studies demonstrated that SMRZ exhibit biexponential decay in water and triexponential decay in CD solutions. The resonance of the aromatic protons of SMRZ showed remarkably upfield shift in the complexes suggested that the aniline ring deeply encapsulated in the CD cavity. The amino and amido stretching vibrations at 3483 cm(-1) and 3379 cm(-1) respectively are strongly affected in the inclusion complexes. DSC curves for the inclusion complexes exhibited a broad endothermic effect from 106.4 °C, 123.8 °C and 234.5 6 °C for α-CD and 118.2 °C and 231.4 °C for β-CD. TEM images of both inclusion complexes are forms a nanochain like agglomerated structures with a width ranging from 40 nm to 100 nm. Thermodynamic parameters and binding affinity of the inclusion complex formation were determined and discussed.

Abstract
The inclusion complexation behavior, characterization and binding ability of sulfadimethoxine (SDMO) with α-cyclodextrin (α-CD) and β-cyclodextrin (β-CD) have been investigated both in solution and solid state by means of absorption, fluorescence, time-resolved fluorescence, (1)H NMR, FT-IR, DSC, SEM, TEM, XRD and molecular modeling methods. The spectral shifts revealed that the part of pyrimidine and aniline rings of SDMO are entrapped in the CD cavity. The stoichiometric ratio and association constant were determined by Benesi-Hildebrand plots and spectroscopic studies respectively. FT-IR spectroscopy was used to compare inclusion systems with physical mixtures, and demonstrated the complex formation in the solid state. The morphology and size of the nanoparticles of SDMO/CD complexes in aqueous solution were observed by TEM. The DSC analysis showed that the thermal stability of SDMO was enhanced in the presence of CD. Investigations of energetic and thermodynamic properties by PM3 method confirmed the stability of the inclusion complexes.
