Strategies for Improving Bioavailability, Bioactivity, and Physical-Chemical Behavior of Curcumin. Molecules 2022; 27:molecules27206854. [PMID: 36296447 PMCID: PMC9608994 DOI: 10.3390/molecules27206854] [Citation(s) in RCA: 23] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 10/04/2022] [Accepted: 10/08/2022] [Indexed: 11/23/2022] Open
Abstract
Curcumin (CCM) is one of the most frequently explored plant compounds with various biological actions such as antibacterial, antiviral, antifungal, antineoplastic, and antioxidant/anti-inflammatory properties. The laboratory data and clinical trials have demonstrated that the bioavailability and bioactivity of curcumin are influenced by the feature of the curcumin molecular complex types. Curcumin has a high capacity to form molecular complexes with proteins (such as whey proteins, bovine serum albumin, β-lactoglobulin), carbohydrates, lipids, and natural compounds (e.g., resveratrol, piperine, quercetin). These complexes increase the bioactivity and bioavailability of curcumin. The current review provides these derivatization strategies for curcumin in terms of biological and physico-chemical aspects with a strong focus on different type of proteins, characterization methods, and thermodynamic features of protein–curcumin complexes, and with the aim of evaluating the best performances. The current literature review offers, taking into consideration various biological effects of the CCM, a whole approach for CCM-biomolecules interactions such as CCM-proteins, CCM-nanomaterials, and CCM-natural compounds regarding molecular strategies to improve the bioactivity as well as the bioavailability of curcumin in biological systems.

Abstract
Curcumin (Cur) is an anti-inflammatory polyphenol that can be complexed with polymeric cyclodextrin (CD) to improve solubility and bioavailability. The aim of the present work was to prepare a CurCD hydrogel to treat inflammatory skin conditions. Epichlorohydrin-β-CD (EpiβCD) was used as polymeric CD. To characterize the binary system, solid-state and in-solution studies were performed. Afterwards, an experimental design was performed to optimize the hydrogel system. Finally, the CurEpiβCD hydrogel system was tested for anti-inflammatory activity using a HaCat psoriasis cell model. Co-grinded Cur/EpiβCD binary system showed a strong interaction and Curcumin solubility was much improved. Its combination with Pluronic® F-127/hyaluronate hydrogel demonstrated an improvement in release rate and Curcumin permeation. After testing its anti-inflammatory activity, the system showed a significant reduction in IL-6 levels. Hydrogel-containing CurEpiβCD complex is a great alternative to treat topical inflammatory diseases.

Abstract
Porous silica materials are often used for drug delivery. However, systems for simultaneous delivery of multiple drugs are scarce. Here we show that anisotropic and amphiphilic dumbbell core-shell silica microparticles with chemically selective environments can entrap and release two drugs simultaneously. The dumbbells consist of a large dense lobe and a smaller hollow hemisphere. Electron microscopy images show that the shells of both parts have mesoporous channels. In a simple etching process, the properly adjusted stirring speed and the application of ammonium fluoride as etching agent determine the shape and the surface anisotropy of the particles. The surface of the dense lobe and the small hemisphere differ in their zeta potentials consistent with differences in dye and drug entrapment. Confocal Raman microscopy and spectroscopy show that the two polyphenols curcumin (Cur) and quercetin (QT) accumulate in different compartments of the particles. The overall drug entrapment efficiency of Cur plus QT is high for the amphiphilic particles but differs widely between Cur and QT compared to controls of core-shell silica microspheres and uniformly charged dumbbell microparticles. Furthermore, Cur and QT loaded microparticles show different cancer cell inhibitory activities. The highest activity is detected for the dual drug loaded amphiphilic microparticles in comparison to the controls. In the long term, amphiphilic particles may open up new strategies for drug delivery.

Abstract
This study deals with the synthesis of a gliadin-stabilized gold quantum cluster (AuQC) for the encapsulation of curcumin (CUR) and its targeted delivery to the cancer cell. CUR is an anticancer drug containing a hydrophobic polyphenol derived from the rhizome of Curcuma longa. The utilization of CUR in cancer treatment is limited because of suboptimal pharmacokinetics and poor bioavailability at the tumor site. In order to improve the bioavailability of CUR, we have encapsulated it into AuQCs stabilized by a proline-rich protein gliadin because proline-rich protein has the ability to bind a hydrophobic drug CUR. The encapsulation of CUR into the hydrophobic cavity of the protein was confirmed by various spectroscopic techniques. Compared to CUR alone, the encapsulated CUR was stable against degradation and showed higher pH stability up to pH 8.5. The encapsulation efficiency of CUR in AuQCs was calculated as 98%, which was much higher than the other reported methods. In vitro drug release experiment exhibited a controlled and pH-dependent CUR release over a period of 60 h. The encapsulated CUR-QCs exhibited less toxicity in the normal cell line (L929) and high toxicity in breast cancer (MDA-MB239). Thus, it can be used as a potential material for anticancer therapy and bioimaging.

Abstract
Purpose: To evaluate the feasibility of soy protein hydrolysates (SPH)-tannic acid (TA) complex nanoparticle obtained by photocatalysis (SPH-T (P)) to construct curcumin (Cur) delivery vehicles. Methods: The interaction behaviour of SPH-T (P) was investigated using Fourier transform infra-red, X-ray diffraction and differential scanning calorimeter analyzes. Formation and stability of the complexes were characterised by particle size, morphology, zeta potential, and in vitro release. Results: Negatively charged Cur-loaded complex with small size (<100 nm), spherical cluster shape and uniform size distribution were formed through the driving force of electrostatic attraction, followed by hydrogen bonding. The presence of photocatalysis in the complexes significantly improved the storage stability and in vitro sustained release of curcumin by enhancing the hydrogen bonding, hydrophobic effects and π-π stacking interactions between SPH and TA. Conclusion: SPH-T (P) would be a useful and promising delivery vehicle for encapsulating, protecting, and delivering hydrophobic nutraceuticals.

Abstract
A newly synthesized PEGylated cholesterol/α-tocopheryl succinate (α-TOS) linked polymer (CV) was self-assembled and loaded with curcumin to form a micellar system (C-CVM). The tri-functionalized amphiphilic polymer was constituted of hydrophobic cholesterol and α-TOS connected to hydrophilic PEG via a lysine linker. The synthesized polymer and the micelles were characterized by 1H NMR, DLS, zeta potentiometer, TEM, CMC determination and hemolysis studies. CVM displayed low CMC value of 15 µM with extent of hemolysis as less than 4%. The stable C-CVM with optimum % drug loading (14.2 ± 0.24) displayed Z average of 175.8 ± 0.68 nm with PDI (0.248 ± 0.075) and released curcumin in sustained manner in the in vitro drug release study. C-CVM demonstrated dose-dependent cellular uptake and cytotoxicity in murine melanoma, B16F10 and human breast cancer, MDA-MB-231 cell lines. CV exhibited marked reversal of drug resistance as indicated by significantly higher retention of P-glycoprotein substrate, rhodamine-123 in the resistant B16F10 cell line compared to standard P-glycoprotein inhibitor, verapamil. C-CVM demonstrated significantly higher spheroidal growth inhibition compared to C-PPM. The results provide strong evidence for CVM as promising drug delivery system and confirm the potential of C-CVM as chemotherapy in cancer.

Abstract
Curcumin is a dominating active component of Curcuma longa and has been studied widely because of its prominent biological activities. The extremely low aqueous solubility, stability, and bioavailability of curcumin limit its application in the field of medicine. In this study, we developed pectin-curcumin (PEC-CCM) conjugates that could self-assemble water-soluble nanomicelles in aqueous solution. The structure of PEC-CCM conjugates was characterized by ultraviolet-visible spectra, fluorescence spectra, Fourier transform infrared spectroscopy, and 1H nuclear magnetic resonance spectroscopy. The thermal property of PEC-CCM conjugates was investigated by thermogravimetric analysis. It was found that PEC-CCM conjugates had formed nanomicelles in aqueous medium via self-assembly. These nanomicelles were observed as small spheres or ellipsoids and aggregated with a size range of 70-190 nm by transmission electron microscopy analysis. In a solution of nanomicelles, the stability of curcumin was improved, and its antioxidant property was preserved. The anticancer activity of PEC-CCM conjugates was quantified by the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay using a hepatic cancer cell line (HepG2), a breast cancer cell line (MCF-7), a cervical cancer cell line (HeLa), and a human normal kidney cell line (293A). It was found that the curcumin of PEC-CCM conjugates had a more significant inhibitory effect on cancer cells and was less cytotoxic to normal cells than free curcumin was. PEC-CCM conjugates have great potential for some food and pharmaceutical applications.

Abstract
Aim: To improve the bioavailability and anticancer potential of curcumin by using a cholesterol-conjugated chitosan micelle. Methods & methods: Cholesterol was conjugated to chitosan (15 kDa) to form self-assembled micelles, which loaded curcumin. Physicochemical characterization and formulation optimization of the drug-loaded micelles (curcumin-loaded chitosan–cholesterol micelles [C-CCM]) were performed. In vitro cellular uptake and viability of C-CCM were investigated in melanoma and breast cancer cell lines. The antitumor efficacy was evaluated in 3D lung cancer spheroid model. Results & conclusion: The optimized C-CCM had size of approximately 162 nm with loading efficiency of approximately 36%. C-CCM was taken up efficiently by the cells, and it reduced cancer cell viability significantly compared with free curcumin. C-CCM enhanced the antitumor efficacy in spheroids, suggesting that C-CCM could be used as an effective chemotherapy in cancer.
