Abstract
The aberrant activation of NLRP3 inflammasome contributes to pathogenesis of multiple inflammation-driven human diseases. However, the medications targeting NLRP3 inflammasome are not approved for clinic use to date. Here, we show that ascorbyl palmitate (AP), a lipophilic derivative of ascorbic acid (AA) and a safe food additive, is a potent inhibitor of NLRP3 inflammasome. Compared with AA, AP inhibited the activation of NLRP3 inflammasome with increased potency and specificity. Mechanistically, AP directly scavenged mitochondrial reactive oxygen species (mitoROS) by its antioxidant activity and blocked NLRP3-NEK7 interaction and NLRP3 inflammasome assembly. Moreover, AP showed more significant preventive effects than AA in LPS-induced systemic inflammation, dextran sulfate sodium (DSS)-induced colitis and experimental autoimmune encephalomyelitis (EAE). Thus, our results suggest that AP is a potential therapeutic combating NLRP3-driven diseases.

Abstract
Adipose tissue stromal cells (ADSCs) are prone to functional decline and senescence during metabolic disturbances. In diabetes mellitus (DM), the pathogenic microenvironment induces oxidative stress causing ADSCs to senesce. The senescence associated secretory phenotype (SASP) in turn drives disease progression. The pathogenesis of DM is thus both a cause and consequence of senescence. Therapeutically preventing the onset of senescence in ADSCs may play a significant role in preventing disease progression and directly impact the onset of comorbidities. The purpose of this study was to establish an in vitro model that mimic the DM micro-environment to use as a screening tool to assess the therapeutic efficacy of preventative and restorative agents. Exposing ADSCs (

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Wu-Zi-Yan-Zong-Wan (WZYZW) is a commonly used Chinese medicinal recipe for oligozoospermia. Oligozoospermia is a common disease that harms human fertility, there is no effective therapeutic medicine at present. However, the underlying pharmacological mechanism remains unclear. METHODS Oligozoospermia rats model induced by Tripterygium glycosides (TG) was established to inspect the efficiency of WZYZW in the treatment of oligozoospermia by traditional pharmacodynamics combined with NMR-based metabolomics. Multivariate statistics were used to extracted the underlying biomarkers and metabolic pathways of WZYZW in the treatment of oligozoospermia. RESULTS The results showed that TG disturbed many metabolites and metabolic pathways such as oxidative stress (choline, O-phosphocholine, betaine and ascorbate), energy metabolism in mitochondria (glucose, lactate, succinate, fumarate, 3-hydroxybutyrate and alanine), mitochondrial apoptosis markers (Bax and Bcl-2) and amino acids metabolisms (arginine, branched-chain amino acids, taurine and myo-inositol). CONCLUSIONS WZYZW could significantly reverse the disturbed metabolites to their normal status by their abilities of anti-oxidation, anti-apoptosis, balancing the osmotic pressure regulatory molecules and regulating the amino acids metabolism. This study provides pharmacological basis and guidance for the clinical usage of WZYZW.

Int J Mol Sci 2019; 20:ijms20194735. [PMID: 31554245 PMCID: PMC6801448 DOI: 10.3390/ijms20194735] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Revised: 09/17/2019] [Accepted: 09/19/2019] [Indexed: 12/22/2022] Open
Abstract
The novel 4-substituted 1,2,3-triazole L-ascorbic acid (L-ASA) conjugates with hydroxyethylene spacer as well as their conformationally restricted 4,5-unsaturated analogues were synthesized as potential antioxidant and antiproliferative agents. An evaluation of the antioxidant activity of novel compounds showed that the majority of the 4,5-unsaturated L-ASA derivatives showed a better antioxidant activity compared to their saturated counterparts. m-Hydroxyphenyl (7j), p-pentylphenyl (7k) and 2-hydroxyethyl (7q) substituted 4,5-unsaturated 1,2,3-triazole L-ASA derivatives exhibited very efficient and rapid (within 5 min) 2,2-diphenyl-1-picrylhydrazyl (DPPH•) radical scavenging activity (7j, 7k: IC50 = 0.06 mM; 7q: IC50 = 0.07 mM). In vitro scavenging activity data were supported by in silico quantum-chemical modelling. Thermodynamic parameters for hydrogen-atom transfer and electron-transfer radical scavenging pathways of anions deprotonated at C2-OH or C3-OH groups of L-ASA fragments were calculated. The structure activity analysis (SAR) through principal component analysis indicated radical scavenging activity by the participation of OH group with favorable reaction parameters: the C3-OH group of saturated C4-C5(OH) derivatives and the C2-OH group of their unsaturated C4=C5 analogues. The antiproliferative evaluation showed that p-bromophenyl (4e: IC50 = 6.72 μM) and p-pentylphenyl-substituted 1,2,3-triazole L-ASA conjugate (4k: IC50 = 26.91 μM) had a selective cytotoxic effect on breast adenocarcinoma MCF-7 cells. Moreover, compound 4e did not inhibit the growth of foreskin fibroblasts (IC50 > 100 μM). In MCF-7 cells treated with 4e, a significant increase of hydroxylated hypoxia-inducible transcription factor 1 alpha (HIF-1α) expression and decreased expression of nitric oxide synthase 2 (NOS2) were observed, suggesting the involvement of 4e in the HIF-1α signaling pathway for its strong growth-inhibition effect on MCF-7 cells.

Abstract
l-Ascorbic acid (ASA), vitamin C, is a ubiquitous carbohydrate-like compound that has an essential role in a number of cellular processes, such as collagen synthesis, cellular oxidation, and various hydroxylation reactions. ASA is a biomolecule of critical importance for protection of cellular components against oxidative damage caused by toxic free radicals and other reactive oxygen species (ROS) that are involved in the development of various types of chronic diseases. Vitamin C has a switchover role from being an antioxidant in physiological conditions to a prooxidant under pathologic conditions. Moreover, some l-ascorbic acid derivatives exhibit strong and selective antitumor and antiviral activity. This review emphasizes the advances on diverse and potent biological profiles of l-ascorbic acid and its derivatives, and their perspective in the development of new bioactive chemical entities in the future. The work is primarily addressed at antioxidant, anticancer, and antiviral potencies of l-ascorbic acid and compounds containing its butenolide structural motif.

Abstract
In this study, Asc-s was evaluated for anti-cancer effect using cervical cancer cells (HeLa). Results determine that Asc-s treatment-induced dose-dependent inhibition of proliferation of HeLa cells and induced apoptosis. Flow-cytometry analysis shows Asc-s treatment-induced accumulation of cells at sub-G0/G1 stage of cell cycle and induced apoptosis as confirmed by DAPI, propodium iodide, and acridine staining in HeLa cells. Asc-s entered the cells and metabolized to ascorbate and stearate moieties, increased membrane permeability, and decreased membrane fluidity in HeLa cells. Asc-s treatment-induced dose-dependent increase in autophagy protein LC3-II, mRNA levels and decreased Nrf-2 levels in HeLa cells. It is hypothesized that both ascorbyl radical and stearoyl moieties of Asc-s induced cytotoxicity by generating reactive oxygen species (ROS) and modulating membrane fluidity/permeability leading to apoptosis/autophagy of HeLa cells. Thus, our findings demonstrate that Asc-s as anti-proliferative and apoptosis inducing compound in cervical cancer cells.

Abstract
Hydrogen water as a new therapeutic antioxidant has been widely used in living organisms under stress. In this study, we applied nanobubble (NB) technology to hydrogen water. The antioxidant capacity of hydrogen NB water was studied with respect to different reactive oxygen species (ROS) both in vitro and in vivo. Using a relatively weak reduced dye, APF, we showed that hydrogen NB water can effectively remove three cytotoxic ROS, •OH, ClO-, and ONOO-, from water. Hydrogen NB water could also remove O2•-, which is a physiologically important ROS, from water. However, hydrogen water could not reduce other physiologically important ROS such as H2O2 and NO. At similar dissolved hydrogen concentrations, hydrogen NB water displayed higher antioxidant activity than hydrogen water without NB. Barley seed germination tests were used to study the antioxidant effect of hydrogen NB water on ROS generation in vivo. Our results showed that this decreased the physiological activity of barley seeds in their normal homeostatic state. Hydrogen NB water eliminated endogenous O2•- in seeds and inhibited germination. The usage of hydrogen NB water should be individually considered according to the types of cells involved. Our results offer basic data concerning the application of hydrogen NB water in different fields.

Abstract
Ascorbic acid (AA) possesses multiple beneficial functions, such as regulating collagen biosynthesis and redox balance in the skin. AA derivatives have been developed to overcome this compound’s high fragility and to assist with AA supplementation to the skin. However, how AA derivatives are transferred into cells and converted to AA in the skin remains unclear. In the present study, we showed that AA treatment failed to increase the cellular AA level in the presence of AA transporter inhibitors, indicating an AA transporter-dependent action. In contrast, torisodium ascorbyl 6-palmitate 2-phosphate (APPS) treatment significantly enhanced the cellular AA level in skin cells despite the presence of inhibitors. In ex vivo experiments, APPS treatment also increased the AA content in a human epidermis model. Interestingly, APPS was readily metabolized and converted to AA in keratinocyte lysates via an intrinsic mechanism. Furthermore, APPS markedly repressed the intracellular superoxide generation and promoted viability associated with an enhanced AA level in Sod1-deficient skin cells. These findings indicate that APPS effectively restores the AA level and normalizes the redox balance in skin cells in an AA transporter-independent manner. Topical treatment of APPS is a beneficial strategy for supplying AA and improving the physiology of damaged skin.

Abstract
AIMS The major challenge of working with valvular interstitial cells in vitro is the preservation or recovery of their native quiescent state. In this study, a biomimetic approach is used which aims to engineer small volume, high quality valve microtissues, having a potential in regenerative medicine and as a relevant 3D in vitro model to provide insights into valve (patho)biology. METHODS AND RESULTS To form micro-aggregates, porcine valvular interstitial cells were seeded in agarose micro-wells and cultured in medium supplemented with 250μM Ascorbic Acid 2-phosphate for 22days. Histology showed viable aggregates with normal nuclei and without any signs of calcification. Aggregates stained strongly for GAG and collagen I and reticular fibers were present. ECM formation was quantified and showed a significant increase of GAG, elastin and Col I during aggregate culture. Cultivation of VIC in aggregates also promoted mRNA expression of Col I/III/V, elastin, hyaluronan, biglycan, decorin, versican MMP-1/2/3/9 and TIMP-2 compared to monolayer cultured VIC. Phenotype analysis of aggregates showed a significant decrease in α-SMA expression, and an increase in FSP-1 expression at any time point. Furthermore, VIC aggregates did not show a significant difference in OCN, Egr-1, Sox-9 or Runx2 expression. CONCLUSION In this study high quality valvular interstitial cell aggregates were generated that are able to produce their own ECM, resembling the native valve composition. The applied and completely cell driven 3D approach overcomes the problems of VIC activation in 2D, by downregulating α-SMA expression and stimulating a homeostatic quiescent VIC state.

Abstract
Mechanical stress and aging are major risk factors of cartilage degeneration. Human studies have previously reported that oxidative damage increased, while SOD2 protein was reciprocally downregulated in osteoarthritic degenerated cartilage. However, it remains unclear whether mitochondrial superoxide imbalance in chondrocytes causes cartilage degeneration. We herein demonstrate that mechanical loading promoted mitochondrial superoxide generation and selective Sod2 downregulation in chondrocytes in vivo and that mitochondrial superoxide inducer also downregulated Sod2 expression in chondrocytes in vitro. A genetically manipulated model revealed that Sod2 deficiency in chondrocytes also resulted in mitochondrial superoxide overproduction and dysfunction, thus leading to cartilage degeneration. Intra-articular injection of a permeable antioxidant effectively suppressed the mechanical loading-induced mitochondrial superoxide generation and cartilage degeneration in mice. Our findings demonstrate that mitochondrial superoxide plays a pivotal role in the development and progression of osteoarthritis, and the mitochondrial superoxide balance may therefore be a promising target for the treatment of cartilage degeneration.

The protective effect of eicosapentaenoic acid-enriched phospholipids from sea cucumber Cucumaria frondosa on oxidative stress in PC12 cells and SAMP8 mice. Neurochem Int 2013; 64:9-17.

Abstract
Alzheimer's disease (AD) is a common neurodegenerative disorders, in which oxidative stress plays an important role. The present study investigated the effect of eicosapentaenoic acid-enriched phospholipids (EPA-enriched PL) from the sea cucumber Cucumaria frondosa on oxidative injury in PC12 cells induced by hydrogen peroxide (H2O2) and tert-butylhydroperoxide (t-BHP). We also studied the effect of EPA-enriched PL on learning and memory functions in senescence-accelerated prone mouse strain 8 (SAMP8) in vivo. Pretreatment with EPA-enriched PL resulted in an enhancement of survival in a dose-dependent manner in H2O2 or t-BHP damaged PC12 cells. EPA-enriched PL pretreatment could also reduce the leakage of lactate dehydrogenase (LDH), and increase the intracellular total antioxidant capacity (T-AOC) and superoxide dismutase (SOD) activity compared with the H2O2 or t-BHP group. The down-regulated Bcl-2 mRNA level and up-regulated Bax, Caspase-9, and Caspase-3 mRNA expression induced by H2O2 or t-BHP could be restored by EPA-enriched PL pretreatment. These results demonstrated that EPA-enriched PL exhibited its neuroprotective effects by virtue of its antioxidant activity, which might be achieved by inhibiting the mitochondria-dependent apoptotic pathway. The neuroprotective effect of EPA-enriched PL was also verified in vivo test: the EPA-enriched PL administration prevented the development of learning and memory impairments in SAMP8 mice. Our results indicated that EPA-enriched PL could offer an efficient and novel strategy to explore novel drugs or functional food for neuronprotection and cognitive improvement.

Abstract
Oxidative stress has been considered as a major cause of cellular injuries in various clinical abnormalities. One of the possible ways to prevent reactive oxygen species (ROS)-mediated cellular injury is dietary or pharmaceutical therapies to augment the endogenous antioxidant defense capacity. The present study found that 2',4'-dihydroxy-6'-methoxy-3',5'-dimethylchalcone (DMC), a chalcone isolated from the buds of Cleistocalyx operculatus, possessed cytoprotective activity in PC12 cells treated with H(2)O(2). The results showed that DMC could effectively increase cell viability [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide (MTT) reduction], decrease the cell apoptotic percentage [annexin V/propidium iodide (AV/PI) assay], prevent the membrane from damage [lactate dehydrogenase (LDH) release], scavenge ROS formation, reduce caspase-3 activity, and attenuate the decrease of mitochondrial membrane potential (MMP) in PC12 cells treated with H(2)O(2). Meanwhile, DMC increased the catalytic activity of superoxide dismutase (SOD) and the cellular amount of glutathione (GSH), decreased the cellular amount of malondialdehyde (MDA), and decreased the production of lipid peroxidation in PC12 cells treated with H(2)O(2).

Abstract
This review presents the rationale for the therapeutic use of antioxidants in treating critically ill patients; it is not a systematic review of the clinical evidence that has been assessed recently by others. Clinical and nonclinical evidence is presented to support the notion that natural antioxidants are of therapeutic value in treating cardiovascular shock. Oxidative stress is a major promoter and mediator of the systemic inflammatory response. The microcirculation is particularly susceptible to oxidative stress that causes hemodynamic instability, leading to multiple organ failure due to systemic inflammatory response syndrome. Vitamin C is the antioxidant used experimentally to demonstrate oxidative stress as a key pathophysiologic factor in septic shock. Pharmacologic studies reveal that vitamin C (as ascorbate), at supraphysiologic doses, significantly affects the bioavailability of nitric oxide during acute inflammation, including inhibiting nitric oxide synthetase induction. Parenteral high-dose vitamin C inhibits endotoxin-induced endothelial dysfunction and vasohyporeactivity in humans and reverses sepsis-induced suppression of microcirculatory control in rodents. In severe burn injury, in both animals and patients, parenteral high-dose vitamin C significantly reduces resuscitation fluid volumes. Therefore, a significant body of pharmacologic evidence and sound preliminary clinical evidence supports the biological feasibility of using the exemplary antioxidant, vitamin C, in the treatment of the critically ill.

Abstract
The release of excessive Zn(2+) from presynaptic boutons into extracellular regions contributes to neuronal apoptotic events, which result in neuronal cell death. However, the mechanisms of Zn(2+)-induced neuronal cell death are still unclear. Therefore, we investigated the dynamics of intracellular Zn(2+), calcium, and reactive oxygen species in PC12 cells. The addition of Zn(2+) produced cell death in a concentration- and time-dependent manner. (45)Ca(2+) influx occurred just after the treatment with Zn(2+), although subsequent hydroxyl radical ((*)OH) production did not begin until 3 h after Zn(2+) exposure. (*)OH production was significantly attenuated in Ca(2+)-free medium or by L-type Ca(2+) channel antagonist treatment, but it was independent of the intracellular Zn(2+) content. Dantrolene treatment had no protective effects against Zn(2+)-induced cell death. Treatment with N-acetyl-L-cysteine blocked (*)OH generation and subsequent cell death. These data indicate that Ca(2+) influx and subsequent (*)OH production are critical events in Zn(2+)-induced toxicity in PC12 cells.

Abstract
Reactive oxygen species are believed to play a very significant role in the pathogenesis of several diseases including Alzheimer's disease and Parkinson's disease. It is reported that the crucial balance between reactive oxygen species generation and antioxidant defense is regarded as a force in a wide variety of chronic diseases. In this paper, PC12 cells were used to study the antioxidative effect of hyperoside. The results indicated that hyperoside could effectively protect PC12 cells against cytotoxicity induced by hydrogen peroxide and tert-butyl hydroperoxide at 160 microg/ml and 100 microg/ml, respectively. The study also showed that hyperoside was no harmful within the tested concentration range and could easily enter into the PC12 cells. With the increasing concentration of hyperoside, cytotoxicity induced by hydrogen peroxide and tert-butyl hydroperoxide was significantly attenuated and the corresponding extracellular lactate dehydrogenase levels decreased concurrently by pretreatment with hyperoside. The results were proved by flow cytometric detection of apoptotic cells. All the above results showed hyperoside could efficiently prevent the PC12 cells from shrinking and turning against apoptosis induced by hydrogen peroxide and tert-butyl hydroperoxide.

Abstract
L-Ascorbyl oleate and L-ascorbyl linoleate were synthesized by an immobilized lipase from Candida antarctica with yields of 38% and 44%, respectively. L-Ascorbyl oleate was stable in sterile culture medium over 12 h at 37 degrees C but L-ascorbyl linoleate degraded by 17%. Ascorbyl oleate had a better protective effect on human umbilical cord vein endothelial cells treated with H2O2 than of L-ascorbic acid-2-phosphate-6-palmitate (Asc2P6P).
