Abstract
The enzyme PACE4 has been validated as a promising therapeutic target to expand the range of prostate cancer (PCa) treatments. In recent years, we have developed a potent peptidomimetic inhibitor, namely, compound C23 (Ac-(DLeu)LLLRVK-4-amidinobenzylamide). Like many peptides, C23 suffers from an unfavorable drug-like profile which, despite our efforts, has not yet benefited from the usual SAR studies. Hence, we turned our attention toward a novel formulation strategy, i.e., the use of cyclodextrins (CDs). CDs can benefit compounds through the formation of "host-guest" complexes, shielding the guest from degradation and enhancing biological survival. In this study, a series of βCD-C23 complexes have been generated and their properties evaluated, including potency toward the enzyme in vitro, a cell-based proliferation assay, and stability in plasma. As a result, a new βCD-formulated lead compound has been identified, which, in addition to being more soluble and more potent, also showed an improved stability profile.

Abstract
β-Cyclodextrin (β-CD) is the potential drug carrier to deliver antitumor drugs like doxorubicin (DOX). However, the mechanism for the inclusion complex formation is still unclear and needs to be explored. This study investigated the effect of pH on the inclusion of DOX into thiolated β-CD (β-CD-SH) by electrochemical and molecular dynamics (MD) simulation. The electrochemical study shows a clear difference at different pH values. The redox peak due to the DOX is strongly influenced by pH. At neutral pH, the peak intensity decreases with time, while slight variation is observed at acidic and basic pH, depicting the association of DOX to the β-CD-SH cavity at neutral pH. Also, due to the association, the charge transfer resistance variation increased with time at neutral pH and decreased at basic and acidic pH. The electrochemical study was further supported by MD simulation, suggesting that the cyclodextrin (CD) ring gets slightly elongated due to the flipping of glucose units, specifically at neutral pH leading to a strong association. Also, another significant result observed that the DOX forms an inclusion complex with β-CD-SH in quinol conformation, not in quinone. Briefly, the study provides the necessary molecular binding information for designing an effective β-CD-based targeted drug delivery system.

Abstract
β-Cyclodextrin (CD) derivatives containing an aromatic triazole ring were studied as potential carriers of the following drugs containing an anthraquinone moiety: anthraquinone-2-sulfonic acid (AQ2S); anthraquinone-2-carboxylic acid (AQ2CA); and a common anthracycline, daunorubicin (DNR). UV-Vis and voltammetry measurements were carried out to determine the solubilities and association constants of the complexes formed, and the results revealed the unique properties of the chosen CDs as effective pH-dependent drug complexing agents. The association constants of the drug complexes with the CDs containing a triazole and lipoic acid (βCDLip) or galactosamine (βCDGAL), were significantly larger than that of the native βCD. The AQ2CA and AQ2S drugs were poorly soluble, and their solubilities increased as a result of complex formation with βCDLip and βCDGAL ligands. AQ2CA and AQ2S are negatively charged at pH 7.4. Therefore, they were less prone to form an inclusion complex with the hydrophobic CD cavity than at pH 3 (characteristic of gastric juices) when protonated. The βCDTriazole and βCDGAL ligands were found to form weaker inclusion complexes with the positively charged drug DNR at an acidic pH (pH 5.5) than in a neutral medium (pH 7.4) in which the drug dissociates to its neutral, uncharged form. This pH dependence is favorable for antitumor applications.

Water-soluble galactosamine derivative of β-cyclodextrin as protective ligand and targeted carrier for delivery of toxic anthracycline drug. Int J Pharm 2020; 589:119834.

Abstract
β-cyclodextrin modified with an electron-rich aromatic triazole linker and targeting moiety (galactosamine) was synthesized and studied as a carrier for the anticancer drug, doxorubicin (DOX), with the aim of targeting the pathological cells, reducing the cardiotoxic side effects and increasing the binding of the drug to DNA. The β-cyclodextrins modified with galactosamine (βCDGAL) are non-toxic and highly soluble in aqueous medium compared to the native βCD and βCD modified only with aromatic moiety, such as triazole linker. Molecular modelling and NMR study gave a deeper insight into the ligand structure, providing an explanation for its increased solubility, and the drug-ligand interactions. The triazole linker strengthened the drug binding and introduced pH dependence of the complex stability constants for βCDGAL derivative, as confirmed by the voltammetry measurements. Spectroscopic studies have shown that entrapment of the DOX in βCDGAL cavity reduces the stability constant of the DOX:Fe(III) complex responsible for the production of cardiotoxic reactive oxygen species and additionally supports the binding of the drug to the double strand DNA. The MTT assay and confocal microscopy results showed that despite encapsulation of the drug in the cyclodextrin molecule, its cytotoxic effect on the liver cancer cell line (HepG2) is comparable to that of the free, non-protected drug.

Abstract
The influence of the pH of the multicomponent cell medium on the performance of doxorubicin (DOX), an anticancer drug, was studied on the examples of cervical (HeLa) and kidney (A498) cancer cell lines. The change of pH of the cell medium to more acidic led to a decrease of DOX toxicity on both cell lines due to the change of drug permeability across the cell membrane as a result of drug protonation. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) studies and lactate dehydrogenase (LDH) release tests have shown low toxicity of the drug, especially in the case of A498 cells, which are characterized by an extremely high glycolytic metabolism. The behavior was ascribed primarily to the increased proton concentration in the peripheral blood follicle in the presence of products of the acidic glycolytic metabolism. It is not observed in the measurements performed in commercially available media since they usually have a neutral pH. In earlier reports on kidney cancer, several mechanisms were discussed, including the metabolism of DOX to its less toxic derivative, doxorubicinol, overexpression of ATP binding cassette subfamily B member 1 (ABCB1) transporters, that remove DOX from the inside of cells; however, there was no focus on the simple but very important contribution of drug protonation described in the present study. Drug pH-dependent equilibria in the cell medium should be considered since changes in the drug form may be an additional reason for multidrug resistance.

Impact of pH and cell medium on the interaction of doxorubicin with lipoic acid cyclodextrin conjugate as the drug carrier. J INCL PHENOM MACRO 2020.

Abstract
AbstractLipoic acid derivative of cyclodextrin, βCDLip, was used as the drug carrier for doxorubicin (DOX) and the stability constants of the DOX–βCDLip were determined in the environment of the cell medium. The experiments were performed in neutral (pH 7.6) and acidified (pH 6.3) cell media containing more than forty interferences including: amino acids, vitamins, lipids and proteins. We proved that the pH of the medium has a noticeable impact on the affinity of the drug towards the carrier. At neutral pH, the formation constants of the complex are higher than at pH 6.3, what is characteristic for the cancer cells microenvironment. Furthermore, the values obtained in both cell media are twice smaller than the values obtained previously for the same complex but in the absence of common cell media components indicating that there is a competition between DOX and some hydrophobic medium components for the complex formation with βCDLip. On the other hand at pH 7.6, the amount of free DOX is highly limited due to the fact that most of DOX is still in the complexed form, while at pH 6.3 the cell media ingredients become strong interferences in the formation of the complex between DOX and the drug carrier. The observed behaviour is due to partial protonation of DOX and to competition between the drug and the lipoic side arm of cyclodextrin for the cyclodextrin cavity. The stability constants of the DOX–βCDLip complex in acidic pH are similar to the values for DOX with native β-cyclodextrin, demonstrating that the strengthening effect of DOX–CD complex resulting from the presence of cyclodextrin’s aromatic substituent (Lip) occurs only in the case of neutral pH. The high value of the stability constant of the DOX–βCDLip complex in cell medium at pH 7.6 indicates high selectivity of βCDLip ligand which would be of importance both for the effective drug delivery and for its application in DOX sensing devices.

Abstract
Novel conjugates of ferrocene with uracil, 5-fluorouracil, tegafur, or acyclovir are reported. Their synthesis involved (i) the azide-alkyne 1,3-dipolar cycloaddition or (ii) the formation of the ester linkage. For the first time, we present an in-depth insight into the supramolecular interactions between β-cyclodextrin and ferrocene-nucleobase derivatives. Spectroscopic and voltammetric analyses performed within this work suggested that the ferrocene or adamantane unit of the conjugates interacted with the β-cyclodextrin's inner cavity. The methods applied for the supramolecular studies included 1H-1H ROESY NMR, 1H NMR titration, Fourier-transform infrared spectroscopy, cyclic voltammetry, fluorescence spectra titration, and 1H DOSY NMR. 1H DOSY NMR was also employed to evaluate the apparent binding constants for all the complexes. The ferrocene-acyclovir conjugate Fc-5 featured the highest apparent binding constant value among all the complexes tested.

Abstract
Chemotherapy still constitutes a basic treatment for various types of cancer. Anthracyclines are effective antineoplastic drugs that are widely used in clinical practice. Unfortunately, they are characterized by high systemic toxicity and lack of tumour selectivity. A promising way to enhance treatment effectiveness and reduce toxicity is the synthesis of systems containing anthracyclines either in the form of complexes for the encapsulation of active drugs or their covalent conjugates with inert carriers. In this respect nanotechnology offers an extensive spectrum of possible solutions. In this review, we discuss recent advances in the development of anthracycline prodrugs based on nanocarriers such as copolymers, lipids, DNA, and inorganic systems. The review focuses on the chemical architecture of the noncovalent nanocarrier-drug systems.

Abstract
AbstractA new and convenient synthetic pathway was developed to produce monosubstituted cyclodextrins with high yields. Each of the β-cyclodextrin derivatives described in this work has an aromatic substituent connected with cyclodextrin core by a pH-sensitive hydrazone linker and a carbon chain. Carbon chains differ in lengths having one or three carbon atoms. The correlation between water solubility and linker length was determined using UV–Vis spectroscopy, while the dependence of hydrazone bond hydrolysis on the electrolyte pH was confirmed by cyclic voltammetry. The pH-dependent complex-formation ability between the hydrazone derivative of cyclodextrin and anthracycline drug was examined by square wave voltammetry. The significantly big solubility and the appropriate pH, at which the hydrolysis of the hydrazone bond occurs, make the newly synthesized derivatives attractive for pharmaceutical and medical applications.

Abstract
Novel biocompatible and biodegradable pH/reduction dual-responsive oxidized alginate-doxorubicin (mPEG-OAL-DOX/Cys) prodrug nanohydrogels were designed for tumor-specific intracellular triggered release of anticancer drug DOX by conjugating DOX via acid-labile Schiff base linkage into the PEGylated oxidized alginate (mPEG-OAL) cross-linked with bioreducible disulfide bond. The effect of the complexation with cyclodextrins (α-CD and β-CD) before or after the cross-linking of the mPEG-OAL on the DOX content and controlled release performance was investigated. It was found that the cyclodextrin inclusion complex prodrug nanohydrogels mPEG(CD)-OAL-DOX/Cys, prepared by cross-linking of the mPEG-OAL after complexation with cyclodextrins, exhibited better pH/reduction dual-responsive controlled release performance than the mPEG-OAL-DOX/Cys(CD) ones prepared by cross-linking of the mPEG-OAL before complexation with cyclodextrins, owing to the supramolecular cross-linking of the adjacent pseudopolyrotaxanes. Especially for the cyclodextrin inclusion complex prodrug nanohydrogels mPEG(α-CD)-OAL-DOX/Cys, DOX was released rapidly under lower pH media mimicking the tumor microenvironment and completely released within 48 h, while the premature leakage under the simulated physiological condition was ∼40%, without burst release in both cases. The cellular toxicity and uptake results demonstrated that the mPEG(α-CD)-OAL-DOX/Cys prodrug nanohydrogels possessed similar inhibition against cancer cell growth in comparison with the free DOX and enhanced drug intracellular accumulation.

Abstract
A non-toxic lipoic acid derivative of β cyclodextrin (βCDLip) with an electron-rich aromatic linker was studied as a carrier for the drug doxorubicin with the aim of decreasing the toxic side effects of this drug. The modified cyclodextrin strengthened the drug binding and differentiated the complex-forming ability with dependence on pH. The stability constants of the complexes were evaluated by voltammetry and spectrofluorometry. Molecular modelling provided deeper insight into the nature of the ligand structure itself and the drug-ligand interactions, showing the different contributions of the self-inclusion of the ligand substituent at different pH values. As a result, the modes of interaction of βCDLip with the drug and factors affecting the stabilities of the complex under the pH conditions of healthy and tumour cells could be discovered and explained.

Abstract
This paper describes the synthesis of a β-cyclodextrin (β-CyD) derivative conjugated with a C,C-glucopyranoside containing a benzene unit. Its doxorubicin-inclusion ability and structure are also discussed. SPR analysis revealed that the β-CyD conjugate had a high inclusion association value of 3.8×10(6)M(-1) for immobilized doxorubicin. NMR structural analysis suggested that its high doxorubicin-inclusion ability was due to the formation of the inclusion complex as a result of the π-π stacking interaction between the benzene ring of the conjugate and the A ring of doxorubicin.

Abstract
Biological barriers are the main defense systems of the homeostasis of the organism and protected organs. The blood-brain barrier (BBB), formed by the endothelial cells of brain capillaries, not only provides nutrients and protection to the central nervous system but also restricts the entry of drugs, emphasizing its importance in the treatment of neurological diseases. Cyclodextrins are increasingly used in human pharmacotherapy. Due to their favorable profile to form hydrophilic inclusion complexes with poorly soluble active pharmaceutical ingredients, they are present as excipients in many marketed drugs. Application of cyclodextrins is widespread in formulations for oral, parenteral, nasal, pulmonary, and skin delivery of drugs. Experimental and clinical data suggest that cyclodextrins can be used not only as excipients for centrally acting marketed drugs like antiepileptics, but also as active pharmaceutical ingredients to treat neurological diseases. Hydroxypropyl-β-cyclodextrin received orphan drug designation for the treatment of Niemann-Pick type C disease. In addition to this rare lysosomal storage disease with neurological symptoms, experimental research revealed the potential therapeutic use of cyclodextrins and cyclodextrin nanoparticles in neurodegenerative diseases, stroke, neuroinfections and brain tumors. In this context, the biological effects of cyclodextrins, their interaction with plasma membranes and extraction of different lipids are highly relevant at the level of the BBB.
