Burcham PC, Le J, Ma L. An immunoblot assay for cysteine oxidation by reactive oxygen species allows detection of novel thioprotective efficacy of black tea extracts. J Pharmacol Toxicol Methods 2021; 108:106957. [PMID: 33636341 DOI: 10.1016/j.vascn.2021.106957] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/09/2021] [Accepted: 02/16/2021] [Indexed: 11/24/2022]
Abstract
INTRODUCTION While cysteine thiol groups help to maintain the redox status of many proteins, they can be very susceptible to damaging oxidants. Despite broad interest in their antioxidant properties, whether tea polyphenols protect against protein thiol damage of this kind is unclear. This study sought to develop a simple immunoassay for use in screening tea extracts and other antioxidants for thioprotective efficacy at protein thiol groups. METHODS Fresh aqueous extracts were prepared from commercially sourced green, white, black and red teas. Traut's reagent (2-iminothiolane) was used to prepare surface-thiolated bovine serum albumin for use as assay substrate in the protein oxidation assay. Oxidative damage was induced during a 15 min incubation with hydrogen peroxide (H2O2) in the presence of tea extracts and reference antioxidants. The substrate protein was then derivatised with dimedone before samples were loaded onto a nitrocellulose membrane housed within a Slot-Blot apparatus. After blocking nonspecific protein binding a commercially available antibody was used to detect dimedone-labelled groups. RESULTS While the total phenol content of tea extracts typically correlated with their activity in lipid peroxidation and galvinoxyl radical-trapping assays, the former did not fully predict their abilities to suppress H2O2-induced cysteine oxidation, with black tea extracts displaying greater activity than the other teas and an apparent ability to reverse pre-existing cysteine oxidation. Among the model antioxidants tested, quercetin displayed a heightened ability to suppress cysteine oxidation. DISCUSSION This slot-blot immunoassay is a convenient method that facilitates standardised comparisons between the thioprotective properties of structurally- and constitutively-diverse antioxidants.

Abstract
Nowadays, cancer is one of the deadliest diseases in the world, which has been estimated to cause 9.9 million deaths in 2020. Conventional treatments for cancer commonly involve mono-chemotherapy or a combination of radiotherapy and mono-chemotherapy. However, the negative side effects of these approaches have been extensively reported and have prompted the search of new therapeutic drugs. In this context, scientific community started to look for innovative sources of anticancer compounds in natural sources, including traditional plants. Currently, numerous studies have evaluated the anticancer properties of natural compounds derived from plants, both in vitro and in vivo. In pre-clinical stages, some promising compounds could be mentioned, such as the sulforaphane or different phenolic compounds. On the other hand, some phytochemicals obtained positive results in clinical stages and were further approved for cancer treatment, such as vinca alkaloids or the paclitaxel. Nevertheless, these compounds are not exempt of limitations, such as low solubility, restricted effect on their own, negative side-effects, etc. This review aims to compile the information about the current phytochemicals used for cancer treatment and also promising candidates, main action mechanisms and also reported limitations. In this sense, some strategies to face the limitations have been considered, such as nano-based formulations to improve solubility or chemical modification to reduce toxicity. In conclusion, although more research is still necessary to develop more efficient and safe phytochemical drugs, more of these compounds might be used in future cancer therapies.

Abstract
Polyphenols (PPs) are the naturally occurring bioactive components in fruits and vegetables, and they are the most abundant antioxidant in the human diet. Studies are suggesting that ingestion of PPs might be helpful to ameliorate metabolic syndromes that may contribute in the prevention of several chronic disorders like diabetes, obesity, hypertension, and colon cancer. PPs have structural diversity which impacts their bioavailability as they accumulate in the large intestine and are extensively metabolized through gut microbiota (GM). Intestinal microbiota transforms PPs into their metabolites to make them bioactive. Interestingly, not only GM act on PPs to metabolize them but PPs also modulate the composition of GM. Thus, change in GM from pathogenic to beneficial ones may be helpful to ameliorate gut health and associated diseases. However, to overcome the low bioavailability of PPs, various approaches have been developed to improve their solubility and transportation through the gut. In this review, we present evidence supporting the structural changes that occur after metabolic reactions in PPs (curcumin, quercetin, and catechins) and their effect on GM composition that leads to improving overall gut health and helping to ameliorate metabolic disorders.

Abstract
Dry age-related macular degeneration and Stargardt disease undergo a known toxic mechanism caused by carbonyl and oxidative stresses (COS). This is responsible for accumulation in the retinal pigment epithelium (RPE) of A2E, a main toxic pyridinium bis-retinoid lipofuscin component. Previous studies have shown that carbonyl stress in retinal cells could be reduced by an alkyl-phloroglucinol-DHA conjugate (lipophenol). Here, we performed a rational design of different families of lipophenols to conserve anti-carbonyl stress activities and improve antioxidant properties. Five synthetic pathways leading to alkyl-(poly)phenol derivatives, with phloroglucinol, resveratrol, catechin and quercetin as the main backbone, linked to poly-unsaturated fatty acid, are presented. These lipophenols were evaluated in ARPE-19 cell line for their anti-COS properties and a structure-activity relationship study is proposed. Protection of ARPE-19 cells against A2E toxicity was assessed for the four best candidates. Finally, interesting anti-COS properties of the most promising quercetin lipophenol were confirmed in primary RPE cells.

Abstract
Introduction: Diabetic neuropathy (DN) is one of the major complications arising from hyperglycaemia in diabetic patients. In recent years polyphenols present in plants have gained attention to treat DN. The main advantages associated with them are their action via different molecular pathways to manage DN and their safety. However, they failed to gain clinical attention due to challenges associated with their formulation development such as lipophilicity,poor bioavailability, rapid systemic elimination, and enzymatic degradation.Area covered: This article includes different polyphenols that have shown their potential against DN in preclinical studies and the research carried out towards development of their nanoformulations in order to overcome aforementioned issues.Expert opinion: In this review various polyphenol based nanoformulations such as nanospheres, self-nanoemulsifying drug delivery systems, niosomes, electrospun nanofibers, metallic nanoparticles explored exclusively to treat DN are discussed. However, the literature available related to polyphenol based nanoformulations to treat DN is limited. Moreover, these experiments are limited to preclinical studies. Hence, more focus is required towards development of nanoformulations using simple and single step process as well as inexpensive and non-toxic excipients so that a stable, scalable, reproducible and non-toxic formulation could be achieved and clinical trials could be initiated.

Abstract
Purpose: This study aimed to investigate the protective effects of quercetin on the tight junction proteins of human retinal pigment epithelial cells (ARPE-19 cells) suffering from oxidative stress injury and explore the possible mechanism.Methods: H2O2 (300 μM) was used to establish an oxidative stress model of ARPE-19 cells. ARPE-19 cells were pretreated with different concentrations (0-80 μM) of quercetin before H2O2 exposure. The expression and distribution of tight junction proteins and autophagy-related proteins were detected by Western blot and immunostaining. ARPE-19 cells were pretreated with 5 mM 3-methyladenine (3-MA).Results: The cell viability weakened in the H2O2 group compared with the control group. However, it was preserved after pretreatment with quercetin. It was observed that the expression levels of occludin, claudin-1 were decreased in the H2O2 group. Quercetin treatment significantly enhanced the expression levels of them as compared to the H2O2 group. H2O2 alone strongly decreased the Zonula occludens protein 1 (ZO-1) expression in the cytomembrane. Quercetin supplementation enhanced the accumulation of ZO-1 in ARPE-19 cells. The expression levels of Beclin-1 and Microtubule associated protein light chain 3 II (LC-3II) increased, and that of P62 decreased in the quercetin protection group. The appearance of LC-3II, which examined by immunofluorescence experiments, enhanced in the quercetin protection group as compared with the control group. The expression levels of beclin-1 and LC-3II increased, and that of P62 increased in the autophagy-inhibited group compared with the quercetin protection group. The levels of occludin and claudin-1 also decreased.Conclusion: Quercetin prevents the loss of tight junction proteins by upregulating autophagy after oxidative stress in ARPE-19 cells.
