Developing an efficient curcumin delivery system based on natural food carriers is a hot topic in both fundamental research and industrial applications. This study successfully prepared curcumin-fortified tofu using tofu as a carrier and an emulsified curcumin encapsulation technology. A systematic investigation was conducted from the perspective of physicochemical and in vitro digestive performance and sensory quality. Results indicate that the soy protein–soybean oil emulsion exhibits a high curcumin encapsulation efficiency and loading capacity. Tofu supplemented with curcumin emulsion developed a unique, dense honeycomb structure with significantly enhanced rheological properties. Simulated digestion experiments demonstrated that curcumin-fortified tofu was digested slowly in the gastric stage, effectively delaying the release of curcumin. The extent of release increased significantly during the intestinal stage, showing the potential for intestinal-targeted delivery. Sensory evaluation confirmed that tofu with 0.10 mg/g of curcumin achieved optimal balance in color, texture, aroma, and taste, demonstrating excellent overall acceptability.

Background: Metal organic compounds have attracted considerable attention since the advent of Salvarsan, a metal organic compound for the treatment of syphilis. Ferrocene as an effective phenyl bioisostere is becoming a viable platform for drug design by virtue of its redox properties,
high lipophilicity and three-dimensional metallocene unit, which may lead to some changes in selectivity toward biological targets compared with phenyl or alkyl groups. Therefore, ferrocene seems to an appropriate candidate for improving the antioxidant activity of drugs. Methods: We
synthesized four ferrocenyl-containing curcumin analogues by introducing ferrocenyl groups into the active methylene groups to obtain higher antioxidant activity than the parent ferrocene- substituted curcumin analogues, and their antioxidant activities were evaluated in 2, 2′- azobis
(2-amidinopropane hydrochloride) (AAPH) and Cu2+/glutathione(GSH) -induced oxidation of DNA, and in trapping 2, 2′-diphenyl-1-picrylhydrazyl (DPPH), 2, 2′-azinobis(3-ethylbenzothiazoline- 6-sulfonate) cationic radicals (ABTS+•) and galvinoxyl radicals. Results: These
ferrocenyl-containing curcumin analogues can protect DNA against Cu2+/GSHinduced oxidation, and scavenge 5.7, 6.9, 5.5 and 5.3 radicals in protecting DNA against AAPHinduced oxidation. Compounds (3)~(5) can trap more DPPH, ABTS+• and galvinoxyl radicals than compound (6). The substituents
and iron atoms play an antioxidant role in ferrocenyl-containing curcumin analogues. Conclusion: The introduction of ferrocenyl group results in a higher antioxidant activity than the traditional hydroxyl-involved curcumin analogues. The ferrocenyl group is a powerful antioxidative group
that could be used to modify natural antioxidants. The electron-accepting group attaching to the phenyl-group could further increase the antioxidant activity. Ferrocene-containing curcumin analogues show higher activities in quenching radicals and protecting DNA against radical-induced oxidation.
Therefore, the introduction of ferrocenyl group into the natural antioxidant may contribute to increase the antioxidant activity.

In this study, curcumin-loaded porous poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) were prepared and surface modified with red blood cell membranes (RBCM) to yield biomimetic[email protected]NPs. The NPs displayed a visible cell-membrane structure at their exterior and had a uniform size of 162 ± 3 nm. In vitro studies showed that drug release from non-porous PLGA NPs was slow and that much of the drug remained trapped in the NPs. In contrast, release was accelerated from the porous PLGA NPs, and after the RBCM coating, a sustained release over 48 h was obtained. Confocal microscopy and flow cytometry results revealed that the RBCM-p-PLGA NPs led to a greater cellular uptake by H22 hepatocarcinoma cells than the uncoated analogue NPs, but could avoid phagocytosis by macrophages. The drug-free formulations were highly biocompatible, while the drug-loaded systems were effective in killing cancer cells.[email protected]NPs possess potent anti-tumor activity in a murine H22 xenograft cancer model (in terms of reduced tumor volume and mass, as well as inducing apoptosis of tumor cells), and have no observable systemic toxicity. Overall, our study demonstrates that the use of the RBCM to cloak nanoscale drug delivery systems holds great promise for targeted cancer treatment, and can ameliorate the severe side effects currently associated with chemotherapy.Keywords:erythrocyte membrane;porous PLGA nanoparticle;curcumin;anticancer therapeutics

The biosynthetic efficiency of curcumin, a highly bioactive compound from the plant Curcuma longa, needs to be improved. In this study, we performed host cell and biosynthetic pathway engineering to improve curcumin biosynthesis. Using in vivo-directed evolution, the expression level of curcuminoid synthase (CUS), the rate-limiting enzyme in the curcumin biosynthetic pathway, was significantly improved. Furthermore, as curcumin is a highly hydrophobic compound, two cell membrane engineering strategies were applied to optimize the biosynthetic efficiency. Curcumin storage was increased by overexpression of monoglucosyldiacylglycerol synthase from Acholeplasma laidlawii, which optimized the cell membrane morphology. Furthermore, unsaturated fatty acid supplementation was used to enhance membrane fluidity, which greatly ameliorated the damaging effect of curcumin on the cell membrane. These two strategies enhanced curcumin biosynthesis and demonstrated an additive effect.

Curcumin (Cur) is a promising photosensitizer that could be used in photodynamic therapy. However, its poor solubility and hydrolytic instability limit its clinical use. The aim of the present study was to encapsulate Cur into solid lipid nanoparticles (SLNs) in order to improve its therapeutic activity. The Cur-loaded SLNs (Cur-SLNs) were prepared using an emulsification and low-temperature solidification method. The functions of Cur and Cur-SLNs were studied on the non-small cell lung cancer A549 cells for photodynamic therapy. The results revealed that Cur-SLNs induced ~2.27-fold toxicity higher than free Cur at a low concentration of 15 μM under light excitation, stocking more cell cycle at G2/M phase. Cur-SLNs could act as an efficient drug delivery system to increase the intracellular concentration of Cur and its accumulation in mitochondria; meanwhile, the hydrolytic stability of free Cur could be improved. Furthermore, Cur-SLNs exposed to 430 nm light could produce more reactive oxygen species to induce the disruption of mitochondrial membrane potential. Western blot analysis revealed that Cur-SLNs increased the expression of caspase-3, caspase-9 proteins and promoted the ratio of Bax/Bcl-2. Overall, the results from these studies demonstrated that the SLNs could enhance the phototoxic effects of Cur.

Superparamagnetic nanomaterials are showing great prospects in medical treatments with targeting medicines. A new conductive superparamagnetic nanocomposite, γ-Fe2O3/polyaniline-curcumin (γ-Fe2O3/PANI-curcumin), was prepared by using the interaction between an amino group in polyaniline and a ketone group in curcumin. The γ-Fe2O3/PANI-curcumin nanocomposite showed superparamagnetism (30 emu·g−1) and electrochemical activity, based on the results of magnetization curve and cyclic voltammetry (CV). Transmission electron microscope (TEM) indicated that the particle size of γ-Fe2O3/PANI-curcumin was between 10 and 50 nm. Fourier transform infrared spectra (FT-IR) and X-ray diffraction (XRD) were used to characterize the γ-Fe2O3/PANI-curcumin nanocomposite, confirming that curcumin was immobilized into the γ-Fe2O3/PANI chain. This study provided an academic foundation for developing a new material for immobilizing an anticancer drug.Keywords:curcumin;maghemite;nanocomposites;polyaniline;superparamagnetism

On-demand curcumin delivery via stimuli-responsive micellar nanocarriers holds promise for addressing its solubility and stability problem. Polymer-curcumin prodrug conjugate micelle is one of such nanosystems. The diversity of linker and conjugation chemistry enabled the generation and optimization of different curcumin micelles with tunable stimuli-responsiveness and delivery efficiency. The aim of the current work was to generate and assess acetal-linked polymeric micelles to enrich the pH-responsive curcumin delivery platforms. Curcumin was slightly modified prior to conjugating to amphiphilic methoxy poly(ethylene glycol)-poly(lactic acid) (mPEG-PLA) copolymer via an acetal bond, whereas an ester bond-linked conjugate was used as the control. The acetal-containing micelles showed a hydrodynamic diameter of 91.1 ± 2.9 (nm) and the accompanying core size of 63.5 ± 7.1 (nm) with a zeta potential of −10.9 ± 0.7 (mV). Both control and pH-labile micelles displayed similar critical micelle concentration at 1.6 μM. The acetal-containing nanocarriers exhibited a pH-dependent drug release behavior, which was faster at lower pH values. The cytotoxicity study in HepG2 cells revealed a significantly lower IC 50 at 51.7 ± 9.0 (μM) for acetal-linked micelles in contrast to the control at 103.0 ± 17.8 (μM), but the polymer residue showed no cytotoxicity upon drug release. The acetal-linked micellar nanocarrier could be a useful addition to the spectrum of currently available stimuli-responsive curcumin nano-formulations.

Post-operative cognitive dysfunction (POCD) is associated with elderly patients undergoing surgery. However, pharmacological treatments for POCD are limited. In this study, we found that curcumin, an active compound derived from Curcuma longa , ameliorated the cognitive dysfunction following abdominal surgery in aged mice. Further, curcumin prevented surgery-induced anti-oxidant enzyme activity. Curcumin also increased brain-derived neurotrophic factor (BDNF)-positive area and expression of pAkt in the brain, suggesting that curcumin activated BDNF signaling in aged mice. Furthermore, curcumin neutralized cholinergic dysfunction involving choline acetyltransferase expression induced by surgery. These results strongly suggested that curcumin prevented cognitive impairments via multiple targets, possibly by increasing the activity of anti-oxidant enzymes, activation of BDNF signaling, and neutralization of cholinergic dysfunction, concurrently. Based on these novel findings, curcumin might be a potential agent in POCD prophylaxis and treatment.

Summary The cost-effective strategy of using paper-based materials as alternatives to plastics can aid in reducing environmental stress. Herein, a novel green low-carbon paper-based food-packaging composite was synthesised: curcumin microcapsule-polyvinyl alcohol/beeswax/chitosan (CURM-PVA/BW/CS) composite papers. Scanning electron microscopy and X-ray diffraction results confirmed that curcumin was successfully encased and adhered to the paper. The water vapour permeability and oxygen transmission rate of the composite papers were 42.28 g (m 2 ·d) −1 and 3.41 cm 3 (m 2 ·d·atm) −1 , respectively. The antioxidant capacity of paper was 93.53%, and the mechanical properties were effectively improved by adding natural antioxidants to the coating. Finally, cakes were packaged in the biodegradable 1%CURM-PVA/BW/CS papers exhibited optimal preservation during the storage period, based on the characterisation of the cake peroxide value, acid value and microbiological count. Overall, the CURM-PVA/BW/CS paper showed great potential for food packaging.

Curcumin (Cur) is a naturally derived, novel anti-inflammatory agent, but its poor solubility limits its clinical use. The aim of the present study was to encapsulate Cur into solid lipid nanoparticles (SLNs) to improve its anti-inflammatory activity. The Cur-loaded SLNs (Cur-SLNs)
were prepared using emulsification and low-temperature solidification methods. In contrast to free Cur, the particles were well dispersed in aqueous medium, showing a narrow size distribution with a range of 55 ± 1.2 nm, a zeta potential value of –26.2 ± 1.3 mV, and a high
drug loading efficiency of 37% ± 2.5%. The sustained release of Cur was observed for up to 6 days. The particles displayed enhanced stability in phosphate-buffered saline by protecting the encapsulated Cur against hydrolysis and biotransformation, as well as increasing biocompatibility.
Cur-SLNs were more effective than free Cur at reducing the expression levels of several proinflammatory mediators, including inflammatory cytokines (IL-6, TNF-α, and IL-1β) and nitric oxide (NO), under in vitro conditions. By Western blotting, we found that
Cur-SLNs were more active than free Cur in inhibiting the LPS-induced activation of the inflammatory transcription factor NF-κB through the suppression of IκB kinase activation. Compared to free Cur, Cur-SLNs had an increased intracellular uptake over time (observed
after 24 h) in RAW264.7 cells. Moreover, the Cur-SLNs (≥20 μM) significantly improved RAW264.7 cell viability by inhibiting apoptosis. Thus, these results demonstrated that SLNs could be used as potential anti-inflammatory drug carriers for the treatment of various chronic diseases.

Galactosylated chitosan–polycaprolactone (Gal-CH–PCL) copolymers with a galactosylation degree of around 10% and varied PCL percentages less than 40 wt% were synthesized and used to produce nanoparticles for delivering curcumin. Some nanoparticles with encapsulation efficiency of 70% or higher and sizes changing from 100 to 250 nm were able to deliver curcumin in a controlled manner. PCL content in Gal-CH–PCLs was found to be a key factor for governing the release behavior of nanoparticles. Hepatocyte-targeted characteristic of nanoparticles was confirmed using human hepatocellular carcinoma (HepG2) cells. In comparison to free curcumin, curcumin-loaded Gal-CH–PCL nanoparticles well retained its anticancer activity. At an equivalent curcumin-dose of around 20 μg/mL that was found to be relatively safe to human normal liver cells, the results obtained from flow-cytometry revealed that some optimized Gal-CH–PCL nanoparticles showed more than 6-fold increasing abilities to induce the apoptosis and necrosis of HepG2 cells during 72 h treatment compared to free curcumin.

Context: The heart is one of the target organs susceptible to attack by sepsis, and protection of the cardiac function in sepsis or alleviation dysfunction caused by sepsis appears a serious and urgent problem.Objective: This study was designed to explore the effect of curcumin on myocardial injury induced by sepsis and to explore the therapeutic effect of curcumin in managing sepsis induced cardiac dysfunction.Methods: Cecal ligation and puncture surgery were used to establish the sepsis model. Curcumin was administered by peritoneal injection (200 mg/kg/d, 3 days). The effects of curcumin on the cardiac functions [Ejection Fraction (EF), Fractional Shortening (FS), Cardiac Output (CO), Heart Rate (HR)], body temperature, cTn I and superoxide dismutase levels, malondialdehyde content (an index of lipid peroxidation), and myocardial histopathological and ultrastructural studies were carried out.Results: We demonstrated that treatment of rats with curcumin significantly decreased elevated levels of cTn I and MDA (p < 0.05) in plasma, and increase the levels of SOD (p < 0.05) after CLP. Moreover, curcumin markedly enhanced the myocardial contractility by increasing the decreased EF and FS in rats with sepsis induced by CLP (p < 0.05). In addition, curcumin could alleviate the myocardial inflammation and structure damage of myocardial cells in sepsis induced by CLP.Conclusion: In conclusion, the results from the present study demonstrate that curcumin has the protective effects on cardiac function in rats with sepsis and curcumin could be considered as an effective and safe therapeutic agent for the management of sepsis induced cardiac dysfunction.
