Abstract: Purpose: Organic Anion Transporting Polypeptide 1B1 (OATP1B1) mediates hepatic influx and clearance of many drugs, including statins. The SLCO1B1 gene is highly polymorphic and its function-impairing variants can predispose patients to adverse effects. The effects of rare genetic variants of SLCO1B1 are mainly unexplored. We examined the impact of eight naturally occurring rare variants and the well-known SLCO1B1 c.521C > T (V174A) variant on in vitro transport activity, cellular localization and abundance. Methods: Transport of rosuvastatin and 2,7-dichlorofluorescein (DCF) in OATP1B1 expressing HEK293 cells was measured to assess changes in activity of the variants. Immunofluorescence and confocal microscopy determined the cellular localization of OATP1B1 and LC-MS/MS based quant. targeted absolute proteomics anal. quantified the amount of OATP1B1 in crude membrane fractions. Results: All studied variants, with the exception of P336R, reduced protein abundance to varying degree. V174A reduced protein abundance the most, over 90% compared to wild type. Transport function was lost in G76E, V174A, L193R and R580Q variants. R181C decreased activity significantly, while T345M and L543W retained most of wild type OATP1B1 activity. P336R showed increased activity and H575L decreased the transport of DCF significantly, but not of rosuvastatin. Decreased activity was interrelated with lower absolute protein abundance in the studied variants. Conclusions: Transmembrane helixes 2, 4 and 11 appear to be crucial for proper membrane localization and function of OATP1B1. Four of the studied variants were identified as loss-of-function variants and as such could make the individual harboring these variants susceptible to altered pharmacokinetics and adverse effects of substrate drugs. In the experiment, the researchers used many compounds, for example, 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0Formula: C20H10Cl2O5).

2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0) belongs to benzofurans derivatives. Benzofurans are compounds with a planar structure having 10 pi electrons that include the lone pair on oxygen atom, which makes it more susceptible to electrophilic attack. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.Formula: C20H10Cl2O5

In spite of the cardiotoxic effect of selective cyclooxygenase-2 inhibitors, they are most widely used as anti-inflammatory and analgesic drugs. Today, valdecoxib and rofecoxib have been withdrawn in the market but celecoxib remains. In this study, we focused on an anal. of celecoxib toxic effects on isolated mitochondria. Isolated rat heart mitochondria were obtained using differential centrifugation. Using flow cytometry and biochem. assays, we searched succinate dehydrogenases, mitochondrial membrane potential (MMP), reactive oxygen species (ROS) formation, mitochondrial swelling, ATP/ADP ratio, lipid peroxidation, and mitochondrial complexes activity in rat heart isolated mitochondria. Herein, our results indicated a significant decrease in the activity of complex IV after exposure with celecoxib (16 Μg/mL). This decrease in the activity of complex IV is paralleled by the MMP collapse, ROS formation, mitochondrial swelling, depletion of ATP, and lipid peroxidation For the first time, this introductory study has shown a significant decrease in the activity of complex IV and mitochondrial dysfunction after exposure with celecoxib in rat heart isolated mitochondria.

JNK/p66Shc/ITCH signaling pathway mediates angiotensin II-induced ferritin degradation and labile iron pool increase was written by Borkowska, Andzelika;Popowska, Urszula;Spodnik, Jan;Herman-Antosiewicz, Anna;Wozniak, Michal;Antosiewicz, Jedrzej. And the article was included in Nutrients in 2020.Application In Synthesis of 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one This article mentions the following:

Angiotensin II (Ang II) induces deleterious changes in cellular iron metabolism and increases the generation of reactive oxygen species. This leads to an impairment of neuronal and vascular function. However, the mechanism underpinning Ang II-induced changes in iron metabolism is not known. We hypothesized that Ang II-induced ferritin degradation and an increase in the labile iron pool are mediated by the c-Jun N-terminal kinase (JNK)/p66Shc/ITCH signaling pathway. We show that Ang II treatment induced ferritin degradation in an endothelial cell lines derived from the bovine stem pulmonary artery (CPAE), human umbilical vein endothelial cells (HUVEC), and HT22 neuronal cells. Ferritin degradation was accompanied by an increase in the labile iron pool, as determined by changes in calcein fluorescence. The JNK inhibitor SP600125 abolished Ang II-induced ferritin degradation Furthermore, the effect of Ang II on ferritin levels was completely abolished in cells transfected with vectors encoding catalytically inactive variants of JNK1 or JNK2. CPAE cells expressing inactive ITCH or p66Shc (substrates of JNK kinases) were completely resistant to Ang II-induced ferritin degradation These observations suggest that Ang II-induced ferritin degradation and, hence, elevation of the levels of highly reactive iron, are mediated by the JNK/p66Shc/ITCH signaling pathway.

Silver Clusters of Five Atoms as Highly Selective Antitumoral Agents Through Irreversible Oxidation of Thiols was written by Porto, Vanesa;Buceta, David;Dominguez, Blanca;Carneiro, Carmen;Borrajo, Erea;Fraile, Maria;Davila-Ferreira, Nerea;Arias, Iria R.;Blanco, Jose M.;Blanco, Maria C.;Devida, Juan M.;Giovanetti, Lisandro J.;Requejo, Felix G.;Hernandez-Garrido, Juan C.;Calvino, Jose J.;Lopez-Haro, Miguel;Barone, Giampaolo;James, Andrew M.;Garcia-Caballero, Tomas;Gonzalez-Castano, Diego M.;Treder, Martin;Huber, Wolfgang;Vidal, Anxo;Murphy, Michael P.;Lopez-Quintela, M.

Low atomicity clusters present properties dependent on the size, due to the quantum confinement, with well-defined electronic structures and high stability. Here it is shown that Ag5 clusters catalyze the complete oxidation of sulfur to S+6. Ag5 catalytic activity increases with different oxidant species in the order O2 â‰?H2O2 < OH·. Selective oxidation of thiols on the cysteine residues of glutathione and thioredoxin is the primary mechanism human cells have to maintain redox homeostasis. Contingent upon oxidant concentration, Ag5 catalyzes the irreversible oxidation of glutathione and thioredoxin, triggering apoptosis. Modification of the intracellular environment to a more oxidized state to mimic conditions within cancer cells through the expression of an activated oncogene (HRASG12V) or through ARID1A mutation, sensitizes cells to Ag5 mediated apoptosis. While cancers evolve to evade treatments designed to target pathways or genetic mutations that drive them, they cannot evade a treatment that takes advantage of aberrant redox homeostasis, which is essential for tumor progression and metastasis. Ag5 has antitumor activity in mice with orthotopic lung tumors reducing primary tumor size, and the burden of affected lymphatic nodes. The findings suggest the unique intracellular redox chem. of Ag5 may lead to new redox-based approaches to cancer therapy.

A new model applied for evaluating a rhenium-diselenium drug: breast cancer cells stimulated by cytokines induced from polynuclear cells by LPS was written by Veena, Vijay;Harikrishnan, Adhikesavan;Lakshmi, Basavegowda;Khanna, Sunali;Desmaele, Didier;Collery, Philippe. And the article was included in Anticancer Research in 2020.Recommanded Product: 76-54-0 This article mentions the following:

Background/aim: New anticancer drugs are usually tested on cancer cells in culture in a standard medium. We stimulated immune polynuclear cells by lipopolysaccharides to obtain an enriched medium (EM) containing inflammatory cytokines more closely reflecting the tumor microenvironment and tested a rhenium-diselenium (Re-diSe) drug in this new model. Concentrations of cytokines were compared with a control medium (CM).</div> Materials and methods: Human-derived breast cancer cells were grown in culture either in CM or EM with or without Re-diSe. Assays of tumor necrosis factor alpha (TNFα), interleukin 6 (IL6), interleukin 1 beta (IL1β), transforming growth factor-beta (TGFβ), insulin growth factor 1 (IGF1) and vascular epidermal growth factor A (VEGFA) were performed by enzyme-linked immunosorbent assays. The production of reactive oxygen species (ROS) was determined by 2,7-dichlorofluorescein test. The cell growth was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide tests. Results: Concentrations of TNFα, IL6 and Il1β were observed to be significantly higher in EM than in CM. There was no difference for TGFβ, IGF1 and VEGFA. The cells were sensitive to Re-diSe, with reduced concentrations of TGFβ, IGF1, VEGFA and ROS, but the half-maximal inhibitory concentration was significantly higher in EM than in CM. Conclusion: The efficacy of the Re-diSe drug was confirmed in this model of aggressive cancer.

Development of a novel and synthetic HematoMiR technology that broadly modulates quiescence of stem cells and enhances HSC expansion was written by Uslu, Merve;Kocabas, Fatih. And the article was included in Cellular and Molecular Life Sciences in 2022.Name: 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one This article mentions the following:

Hematopoietic stem cell (HSCs) transplantation is the primary therapeutic modality used to treat hematopoietic disorders. It centers on the capability of a small quantity of HSCs to repopulate whole blood lineages. Along with limited availability of suitable donors, the need for sufficient number of donor HSCs is still challenging in clin. relevance. This has been addressed by ex vivo HSC expansion albeit with partial success, and thus development of an alternative strategy that could improve HSC expansion is required. To that end, we aimed to build HematoMiR, an oligo-based technol. that broadly targets HSC quiescence factors. Here, we show that HematoMiRs and their combinations targeting over 50 factors involved in HSC quiescence could induce robust ex vivo murine and human HSC expansion. In particular, HematoMiR-5 treatment enhanced cell cycle through down-regulation of neg. cell cycle regulators in HSCs. HematoMiR-5 treated HSPCs had reduced DNA damage during the course of ex vivo expansion. Moreover, HematoMiR-5 treatment led to sustained HSC self-renewal ability and a low apoptosis rate. In addition, HematoMiR-5 expanded HSCs demonstrated successful engraftment and repopulation capacity in the recipient animals. Furthermore, combinatorial treatments of HematoMiR-2 and 5 allowed vigorous ex vivo HSC expansion. These findings demonstrate that novel and synthetic HematoMiR technol. is feasible for HSC ex vivo expansion through the sequence-dependent modulation of numerous HSC quiescence modulators.

And the article was included in Purinergic Signalling in 2020.Recommanded Product: 76-54-0 This article mentions the following:

Sepsis is a severe disease characterized by an uncontrolled systemic inflammation and consequent organ dysfunction generated in response to an infection. Extracellular ATP acting through the P2X7 receptor induces the maturation and release of pro-inflammatory cytokines (i.e., IL-1β) and the production of reactive nitrogen and oxygen species that lead to oxidative tissue damage. Here, we investigated the role of the P2X7 receptor in inflammation, oxidative stress, and liver injury in sepsis. Sepsis was induced by cecal ligation and puncture (CLP) in wild-type (WT) and P2X7 knockout (P2X7-/-) mice. The oxidative stress in the liver of septic mice was assessed by 2′,7′-dichlorofluorescein oxidation reaction (DCF), thiobarbituric acid-reactive substances (TBARS), and nitrite levels dosage. The status of the endogenous defense system was evaluated through catalase (CAT) and superoxide dismutase (SOD) activities. The inflammation was assessed histol. and by determining the expression of inflammatory cytokines and chemokines by RT-qPCR. We observed an increase in the reactive species and lipid peroxidation in the liver of septic WT mice, but not in the liver from P2X7-/- animals. We found an imbalance SOD/CAT ratio, also only WT septic animals. The number of inflammatory cells and the gene expression of IL-1 β, IL-6, TNF-α, IL-10, CXCL1, and CXCL2 were higher in the liver of WT septic mice in comparison to P2X7-/- septic animals. In summary, our results suggest that the P2X7 receptor might be a therapeutic target to limit oxidative stress damage and liver injury during sepsis.

Parkinson’s disease (PD) is the most common neurodegenerative disease. Daidzein (DAI) is one of the most commonly ingested phytoestrogens with anti-oxidant properties. However, the effects of DAI on oxidative stress in PD has not been reported. In this study, we used 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) for i.p. injection of C57/BL6J mice for continuous 7 days to simulate the pathol. process of PD. Results showed that DAI improved the movement disorders and reduced the loss of DA neurons in the brain of mice induced by MPTP. Mechanistically, in vitro, DAI pretreatment up-regulated the expression of Nrf2 and its downstream SOD1 and SOD2 by inhibiting the activity of GSK3β in lipopolysaccharide-stimulated BV2 cells; in vivo, DAI pretreatment attenuated GSK3β activity, increased the expression of Nrf2 and downstream anti-oxidants SOD1, SOD2 and CAT. Our data demonstrated that DAI restrains oxidative stress in PD by regulating the GSK3β/Nrf2 pathway.

Involvement of sex hormones, oxidative stress, ACE and ACE2 activity in the impairment of renal function and remodelling in SHR was written by Melo, Antonio F.

Hypertension is a relevant sex and sex hormones-dependent risk factor where the cardiovascular and renal health of the population are concerned. Men experience greater losses of renal function (RF) than women, but the mechanisms remain somewhat unclear. Our goal was to evaluate the relationship between oxidative stress (OS), angiotensin-converting enzyme (ACE) and angiotensin-converting enzyme 2 (ACE2) activities and RF in male and female SHR. Twelve-week-old spontaneously hypertensive rats (SHR) were submitted to either castration or SHAM surgery and divided into 4 groups, SHAM or Castrated (CAST) males or females. After 51 days we evaluated RF (inulin and sodium para-aminohippurate), ACE and ACE2 activities (fluorimetry), OS (flow cytometry), collagen deposition (picrosirius red) and protein expression (western blot). Males presented lower RF than females and castration impaired this parameter in both groups. Sexual dimorphism was not observed regarding OS and inflammation; however, castration increased this parameter more severely in males than in females. SHAM males exhibited higher collagen deposition than females, though castration increased it in both sexes, eliminating the difference. We found sexual dimorphism regarding renal ACE and ACE2 activities, which were lower in males than in females. Although castration did not alter ACE activity, it reduced ACE2 activity in females and increased it in males. These results indicate that sex hormones affect RF in SHR. As alterations in the oxidative system were capable of promoting podocyte injury, inflammation, and collagen deposition, we put forward that these effects are differently modulated by ACE and ACE2.
