Oral administration of combinations of specific nutrients and nutraceuticals can provide synergistic health benefits to humans. In this work, zein/carboxymethyl cellulose composite nanoparticles were successfully prepared using antisolvent precipitation methods. Zein/carboxymethyl cellulose nanoparticles with the smallest size (204.6 nm) were formed when the mass ratio of zein to CMC was 2 : 1. Hydrogen bonding and hydrophobic interactions were dominant binding forces to stabilize the composite nanoparticles. Quercetin and resveratrol were then encapsulated within these nanocarriers, which improved their resistance to both light and thermal degradation. Encapsulation of the nutraceuticals was shown to delay their release under simulated gastrointestinal conditions, which may be beneficial for some applications. Moreover, encapsulation increased the in vitro bioaccessibility of the quercetin and resveratrol. Our results indicate that zein/carboxymethyl cellulose nanoparticles can be used to co-deliver combinations of bioactive compounds, which may be useful for the development of functional foods, supplements, and pharmaceuticals.

The integration of flame-retardant additive with both excellent thermal stability and remarkable fire-retarded efficiency into epoxy resins (EP) is highly demanded while challenging. Herein, a novel bio-based flame retardant (referred to DPOR) was synthesized via one-step reaction of resveratrol and diphenylphosphonyl chloride. The as-prepared DPOR exhibited outstanding thermal stability, with an initial thermal decomposition temperature of 438.4 °C, contributing from the reduced intermolecular π–π interaction and incremental oligomerization during the heating process. It was further utilized as additive for the manufacture of high-performance EP composites (EP-DPOR). Notably, DPOR can also act as mechanical reinforcer that enhanced the strength and toughness of EP. The EP-DPOR3 (3 wt% DPOR) showed a superior stretchability (15.9 %) and high tensile strength (59.3 MPa) compared to neat EP (12.4 %, 46.7 MPa). Additionally, the burning test results indicated that DPOR endowed the EP with greatly enhanced flame resistance, achieving a UL-94 V-0 rating with an increase of LOI values to 34.5 % at a low loading of 5 wt%. In cone calorimeter tests, it showed that heat and smoke release was effectively inhibited during combustion in comparison with EP, wherein the PHRR value of EP-DPOR was 27.5 % lower than EP. Thus, it is highly anticipated that DPOR, as a new type of bio-based flame retardant with superior thermal stability and efficient flame- retardant properties, holds a great potential for the development of next-generation flame retardant.

Background Resveratrol, a well-known natural compound and nutrient, activates the deacetylation ability of SIRT1, demonstrating p53-dependent apoptosis functions in many diseases. However, the nascent proteomic fluctuation caused by resveratrol is still unclear. Objective In this study, we investigated the effect of resveratrol on the nascent proteome and transcriptome initiated by SIRT1 activation, and we explored the mechanism of resveratrol in HEK 293T cells. Methods Bioorthogonal noncanonical amino acid tagging (BONCAT) is a method used to metabolically label nascent proteins. In this strategy, L-azidohomoalanine (AHA) was used to replace methionine (Met) under different conditions. Taking advantage of the click reaction between AHA and terminal alkyne- and disulfide-functionalized agarose resin (TAD resin), we were able to efficiently separate stimulation responsive proteins from the pre-existing proteome. Resveratrol responsive proteins were identified by Liquid Chromatograph-Mass Spectrometer/Mass Spectrometer (LC-MS/MS). Furthermore, changes in mRNA levels were analyzed by transcriptome sequencing. Results Integrational analysis revealed a resveratrol response in HEK 293T cells and showed that Hsp60 was downregulated at both the nascent protein and mRNA levels. Knockdown of SIRT1 and Hsp60 provides evidence that resveratrol downregulated Hsp60 through SIRT1 and that Hsp60 decreased p53 through the Akt pathway. Conclusions This study revealed dynamic changes in the nascent proteome and transcriptome in response to resveratrol in HEK 293T cells and demonstrated that resveratrol downregulates Hsp60 by activating SIRT1, which may be a possible mechanism by which resveratrol prevents p53-dependent apoptosis by regulating Hsp60.

The synergistic therapeutic benefits of resveratrol (RES) and piperine (PIP) have been proven for the treatment of various diseases. This study reports, for the first time, spray-drying of hydroxypropyl β-cyclodextrin (HP-β-CD) microcapsules for combined delivery of resveratrol and piperine. Phase solubility studies indicated that there was a strong interaction between the active ingredients and HP-β-CD, and both active ingredients can bind stably to HP-β-CD. The results of FTIR, XRD, and DSC demonstrated that RES-PIP/HP-β-CD inclusion complexes were successfully formed, with the RES and PIP encapsulated into the hollow spherical cavity of HP-β-CD. The results of SEM showed that the spray-dried microcapsules displayed a smooth surface and uniform particle size. Upon the formation of the spray-dried microcapsules, both RES and PIP presented significantly enhanced solubility. The results of DPPH and ABTS+scavenging activity assays showed that the spray-drying process did not adversely influence the antioxidant activity of the bioactives, and the addition of PIP increased the antioxidation performance of RES.Keywords:resveratrol;piperine;hydroxypropyl β-cyclodextrin;spray-drying;solubility;antioxidant

ABSTRACT This study discusses the effects of resveratrol ( RES ) on the productive performance, immune function and intestinal barrier function of broiler chickens challenged with lipopolysaccharide ( LPS ). Two hundred and forty 1-day-old male Arbor Acres broilers were randomly divided into 4 groups of 6 replicates each, with 10 broilers per replicate. This experiment used a 2 × 2 factorial design with dietary factors (basal diets or basal diets supplemented with 400 mg/kg RES were administered from d 1 to 21) and stress factors (intraperitoneal injection of 0.5 mg/kg BW of saline or LPS at 16, 18 and 20 d of age). The results showed that LPS challenge had a significant adverse effect on average daily gain ( ADG ) in broilers at 16 to 21 d of age ( P < 0.05), whereas the addition of RES to the diet inhibited the LPS-induced decrease in ADG ( P < 0.05). RES also alleviated LPS-induced immune function damage in broilers, which was manifested by the decrease of spleen index ( P < 0.05) and the recovery of serum immunoglobulin M and ileal secretory immunoglobulin A content ( P < 0.05). The LPS challenge also disrupts intestinal barrier function and inflammation, and RES mitigates these adverse effects in different ways. RES attenuated LPS-induced reduction of villus height in the jejunum and ileum of broilers ( P < 0.05). LPS also caused an abnormal increase in plasma D-lactic acid levels in broilers ( P < 0.05), which was effectively mitigated by RES ( P < 0.05). LPS challenge resulted in a significant decrease in mRNA expression of occludin in the intestinal mucosa ( P < 0.05), which was mitigated by the addition of RES ( P < 0.05). RES significantly decreased the mRNA expression of toll-like receptor 4, nuclear factor kappa-B and tumor necrosis factor alpha in the ileum tissue stimulated by LPS ( P < 0.05). Taken together, this study shows that RES exerts its beneficial effect on broilers challenged with LPS by alleviating immune function damage, relieving intestinal inflammation and barrier damage, and thus improving growth performance.

Resveratrol and its analogs are phytochemicals. Human 3β-hydroxysteroid dehydrogenase 1 (3β-HSD1) synthesizes steroid hormones for normal pregnancy or promoting cancer metastasis. Whether they inhibit 3β-HSD1 remains unclear. In this study, the inhibitory potency, mode of action, structure–activity relationship, and docking parameters of resveratrol and its analogs on 3β-HSD1 and rat homolog 3β-HSD4 were analyzed. The inhibitory potency of these chemicals on human 3β-HSD1 was 4,4′-dihydroxystilbene (IC50, 3.68 μM) > pinostilbene (8.07 μM) > pinosylvin (10.60 μM) > lunularin (26.84 μM) > resveratrol (30.20 μM) > dihydroresveratrol (>100 μM) = oxyresveratrol (>100 μM) > dihydropinosylvin (ineffective at 100 μM). Resveratrol analogs and metabolites are mixed or competitive inhibitors of human 3β-HSD1. Resveratrol and 4,4′-dihydroxystilbene inhibited progesterone secretion by human JAr cells at ≥1 μM. Resveratrol (IC50, 32.09 μM) and pinosylvin (34.71 μM) significantly inhibited rat placental 3β-HSD4 activity. Docking analysis shows that resveratrol analogs and metabolites bind the steroid-binding sites of human 3β-HSD1 and rat 3β-HSD4 and interact with the catalytic residues Ser125/Thr125 and Tyr155. The negative correlation of LogP and IC50 values for human 3β-HSD1 indicates that lipophilicity of chemicals plays a critical role in the inhibitory effect of chemicals. In conclusion, 4,4′-dihydroxystilbene, pinostilbene, and pinosylvin effectively inhibit human 3β-HSD1 depending on their lipophilicity, thereby acting as potential therapeutic agents.

An accurate method was developed to analyze trans - and cis -resveratrols in peanut oils using stable isotope dilution ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). The linearity ranges for trans - and cis -resveratrols were determined to be 0.2–100 μg/kg, exhibiting satisfactory correlation coefficients ( r 2 trans > 0.9998, r 2 cis > 0.9996). The limits of detection (LOD) and the limit of quantification (LOQ) were determined to be 0.06 and 0.2 μg/kg, respectively. The recoveries of spiked oil samples ranged from 94.9 to 105.0%, with relative standard deviations (RSDs) less than 6.5% (intra-day) and 7.6% (inter-day). This method was successfully applied to quantify the contents of trans - and cis -resveratrols in commercial peanut oils, ranging from 8.7 to 55.5 μg/kg and 0 to 11.0 μg/kg, respectively. The results demonstrated that the developed method is simple, reliable, and robust for quantifying trans - and cis -resveratrols in peanut oils. Consequently, it exhibits great potential for evaluating adulteration and ensuring the quality control of peanut oils.

Resveratrol (Res) is known for its potential in treating various types of cancers, with a particular advantage of causing minimal toxic side effects. However, its clinical application is constrained by challenges such as poor bioavailability, low water solubility, and chemical instability in neutral and alkaline environments. In light of these limitations, we have developed a pH-responsive drug delivery nanoplatform, Res@ZIF-8/TA NPs, which exhibits good biocompatibility and shows promise for in vitro cancer therapy. Benefiting from the mild reaction conditions provided by zeolitic imidazolate frameworks (ZIFs), a “one-pot method” was used for drug synthesis and loading, resulting in a satisfactory loading capacity. Notably, Res@ZIF-8/TA NPs respond to acidic environments, leading to an improved drug release profile with a controlled release effect. Our cell-based experiments indicated that tannic acid (TA) modification enhances the biocompatibility of ZIFs. 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di- phenytetrazoliumromide (MTT assay), Hoechst 33342/PI staining, cell scratch assay, Transwell and Reverse Transcription quantitative PCR (RT-qPCR) assays further demonstrated that Res@ZIF-8/TA NPs inhibited colon cancer cell migration and invasion, and promoted apoptosis of colon cancer cells, suggesting a therapeutic potential and demonstrating anti-cancer properties. In conclusion, the Res@ZIF-8/TA NPs pH-responsive drug delivery systems we developed may offer a promising avenue for cancer therapy. By addressing some of the challenges associated with Res-based treatments, this system could contribute to advancements in cancer therapeutics.

Resveratrol (RSV) is a natural flavonoid polyphenol compound extracted from the plants which shows various biological activities. However, the clinical application of RSV is limited by its poor aqueous solubility, rapid metabolism and poor bioavailability. In this study, resveratrol-loaded solid lipid nanoparticles (RSV- SLNs) was design as a nano-antioxidant against the physical fatigue. The resultant RSV-SLNs were characterized by photon correlation spectroscopy (PCS), transmission electron micrographs (TEM), zeta potential, differential scanning calorimetry (DSC) and Raman spectroscopy pattern. Furthermore, the in vivo anti-fatigue effect assays showed that RSV-SLNs prolonged the mice exhausted time and running distance. The biochemical parameters of blood related to fatigue suggested that RSV-SLNs have potential applications to improve the antioxidant defense of the mice after extensive exercise and confer anti-fatigue capability. Furthermore, the molecular mechanisms of antioxidant by RSV-SLNs supplementation was investigated through the analysis of silent information regulator 2 homolog 1 (SIRT1) protein expression, which demonstrated that it could downregulate the expression of SIRT1 and increase autophagy markers, microtubule-associated protein 1 light chain 3-II (LC3-II) and sequestosome-1 (SQSTM1/p62). These results reveal that the RSV-SLNs may have great potential used as a novel anti-fatigue sports nutritional supplement.Keywords:solid lipid nanoparticles (SLNs);resveratrol;drug delivery;anti-fatigue;nutrition supplements

Resveratrol (Res) is a naturally occurring antioxidant with various health benefits, but the poor water solubility and low bioaccessibility of Res limit its application as a food additive . Corn soluble dietary fiber , resistant starch and resistant maltodextrin were used to increase the water solubility of Res via preparation of composite. High dissolution rate and rapid release was achieved for Res in the composites due to its increased water solubility, and the Weibull model was suitable for describing the release of Res from the composites. Additionally, the bioaccessibility of Res in composites was about 2.5 times that of raw Res. In storage experiments, the composites still exhibited good properties after 12 months of storage. The results indicated that Res-dietary fiber composites had good potential.

Resveratrol (RSV) and polydatin (PD) have been widely used to treat several chronic diseases, such as atherosclerosis, pulmonary fibrosis, and diabetes, among several others. However, their low solubility hinders their further applications. In this work, we show that the solubility of PD can be boosted via its co-crystallization with L-proline (L-Pro). Two different phases of co-crystals, namely the RSV-L-Pro (RSV:L-Pro = 1:2) and PD-L-Pro (PD:L-Pro = 1: 3), have been prepared and characterized. As compared to the pristine RSV and PD, the solubility and dissolution rates of PD-L-Pro in water (pH 7.0) exhibited a 15.8% increase, whereas those of RSV-L-Pro exhibited a 13.8% decrease. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay of pristine RSV, PD, RSV-L-Pro, and PD-L-Pro against lung cancer cell line A549 and human embryonic kidney cell line HEK-293 indicated that both compounds showed obvious cytotoxicity against A549, but significantly reduced cytotoxicity against HEK-293, with PD/PD-L-Pro further exhibiting better biological safety than that of RSV/RSV-L-Pro. This work demonstrated that the readily available and biocompatible L-Pro can be a promising adjuvant to optimize the physical and chemical properties of RSV and PD to improve their pharmacokinetics.Keywords:resveratrol;polydatin;L-proline;pharmaceutical co-crystal;crystal structure;solubility and dissolution rate

For preparation of resveratrol and arctigenin from peanut hulls and arctium lappa fruits, respectively, a recombinant β-glucosidase (TmBglA) from hyperthermophile Thermotoga maritima was purified and characterized. The hydrolytic activity was the highest at 90 °C and pH 6.2 for arctiin with Km of 1.61 mM and kcat of 197.4 s−1, and 90 °C and 5.8 for polydatin with Km of 0.38 mM and kcat of 47.6 s−1. The enzyme produced 215.4 mg L−1 resveratrol and 355.7 mg L−1 arctigenin from 400 mg L−1 polydatin and 540 mg L−1 arctiin after 60 min of incubation at 80 °C, with capable of hydrolyzing up to 92.1 and 94.9% of polydatin and arctiin, respectively. The enzymatic hydrolysis of peanut hulls and fructus arctii displayed a conversion yield of 3.8 and 0.33 mg resveratrol and arctigenin per gram of substrate material flour, respectively. Of the reported β-glucosidase, TmBglA exhibited the highest thermostability, kcat, kcat/Km, and conversion productivity for hydrolyzing polydatin and arctiin, and has great potential applications in functional food and medicine production.
