Bui, Khoa;Wemyss, Alan M.;Zhang, Runan;Nguyen, Giao T. M.;Vancaeyzeele, Cedric;Vidal, Frederic;Plesse, Cedric;Wan, Chaoying research published 《 Tailoring Electromechanical Properties of Natural Rubber Vitrimers by Cross-Linkers》, the research content is summarized as follows. The growing demand for smart polymeric transducers such as dielec. elastomer actuators and energy harvesters has urged the use of sustainable and recyclable elastomeric materials. Vitrimer chem. has shed light on future reprocessable and recyclable thermosets and elastomers. In this work, epoxidized natural rubber (ENR) vitrimers were prepared using diacid or triacid crosslinkers and formed covalently crosslinking networks via thermally triggered reversible β-hydroxy ester bonds. The crosslinked ENR elastomers exhibited Arrhenius-type viscoelastic behavior with a complete stress relaxation between 140 and 160°C, i.e., vitrimer characteristics, which were highly dependent on the crosslinking temperature The mech. and dielec. properties of the ENR vitrimers can be tuned by varying the mol. structure and concentration of the crosslinkers. Among the diacid and triacid crosslinkers, Pripol 1017 fatty polyacid (P1017) and 3,3′-dithiopropionic acid (DTPA) had similar effects on the crosslinking d. and mech. properties of the ENR vitrimers. The highest tensile strength of 8.70 ± 1.9 or 15.6 ± 2.6 MPa was obtained at 6 mol % of P1017 or DTPA, resp. While for diamide-based diacid crosslinker (DME), 8 mol % was needed to reach the highest tensile strength of 13.1 ± 2.7 MPa for the elastomer. The three ENR vitrimers showed increased relative permittivity ε’ = 5~7 at 1 kHz while maintaining low dielec. losses compared to traditional dicumyl peroxide-cured ENR, with ε’ = 3.57 at 1 kHz. With the optimized acidic crosslinker concentrations of P1017 at 6 mol %, DTPA at 6 mol %, and DME at 8 mol %, the ENR vitrimers exhibited improved actuation capabilities at lower elec. fields. Utilizing dynamic crosslinkers to tune the electromech. properties of dielec. elastomers and the reversibly crosslinked polymer networks will open new opportunities for smart and sustainable dielec. elastomer devices.

Busby, Robert W.;Cai, Xiaokun;Yang, Sihyung;Ramos, Luis;Venkatarangan, Lata;Shen, Helen;Wax, Stephen;Sadeque, Abu J. M.;De Colle, Cyril research published 《 Metopimazine is primarily metabolized by a liver amidase in humans》, the research content is summarized as follows. Metopimazine (MPZ) is a peripherally restricted, dopamine D2 receptor antagonist used for four decades to treat acute nausea and vomiting. MPZ is currently under clin. investigation for the treatment of gastroparesis (GP). MPZ undergoes high first-pass metabolism that produces metopimazine acid (MPZA), the major circulating metabolite in humans. Despite a long history of use, the enzymes involved in the metabolism of MPZ have not been identified. Here we report a series of studies designed to identify potential MPZ metabolites in vitro, determine their clin. relevance in humans, and elucidate the enzymes responsible for their formation. The findings demonstrated that the formation of MPZA was primarily catalyzed by human liver microsomal amidase. Addnl., human liver cytosolic aldehyde oxidase (AO) catalyzes the formation of MPZA, in vitro, although to a much lesser extent. Neither cytochrome P 450 enzymes nor flavin-monooxygenases (FMO) were involved in the formation MPZA, although two minor oxidative pathways were catalyzed by CYP3A4 and CYP2D6 in vitro. Anal. of plasma samples from subjects dosed 60 mg of MPZ verified that these oxidative pathways are very minor and that CYP enzyme involvement was negligible compared to microsomal amidase/hydrolase in overall MPZ metabolism in humans. The metabolism by liver amidase, an enzyme family not well defined in small mol. drug metabolism, with minimal metabolism by CYPs, differentiates this drug from current D2 antagonists used or in development for the treatment of GP.

Breast Cancer (BC) is a leading cause of death in women, currently affecting 13% of female population worldwide. First-line clin. treatments against Estrogen Receptor pos. (ER+) BC rely on suppressing estrogen production, by inhibiting the aromatase (AR) enzyme, or on blocking estrogen-dependent pro-oncogenic signaling, by targeting Estrogen Receptor (ER) α with selective Modulators/Degraders (SERMs/SERDs). The development of dual acting mols. targeting AR and ERα represents a tantalizing alternative strategy to fight ER + BC, reducing the incidence of adverse effects and resistance onset that limit the effectiveness of these gold-standard therapies. Here, in silico design, synthesis, biol. evaluation and an at.-level characterization of the binding and inhibition mechanism of twelve structurally related drug-candidates enable the discovery of multiple compounds active on both AR and ERα in the sub-μM range. The best drug-candidate 3a displayed a balanced low-nanomolar IC₅₀ towards the two targets, SERM activity and moderate selectivity towards a BC cell line. Moreover, most of the studied compounds reduced ERα levels, suggesting a potential SERD activity. This study dissects the key structural traits needed to obtain optimal dual acting drug-candidates, showing that multitarget compounds may be a viable therapeutic option to counteract ER + BC.

Cai, Yun;Wang, Zhixiao;Liu, Xiaoyun;Wei, Ling;Li, Shushu;Zheng, Xuqin;Yang, Tao;Xu, Xinyu research published 《 The frequency of intrathyroidal follicular helper T cells varies with the progression of Graves’ disease and Hashimoto’s thyroiditis》, the research content is summarized as follows. Autoimmune thyroid diseases (AITD), mainly Graves’ disease (GD) and Hashimoto’s thyroiditis (HT), are common organ-specific autoimmune diseases characterized by circulating antibodies and lymphocyte infiltration. Follicular helper T (Tfh) cell dysregulation is involved in the development of autoimmune pathologies. We aimed to explore the role of intrathyroidal and circulating Tfh cells in patients with GD and HT. Ultrasound-guided thyroid fine-needle aspiration (FNA) was conducted in 35 patients with GD, 40 patients with HT, and 22 patients with nonautoimmune thyroid disease (nAITD). Peripheral blood samples were also obtained from 40 patients with GD, 40 patients with HT, and 40 healthy controls. The frequencies of intrathyroidal and circulating Tfh cells from FNA and peripheral blood samples were assessed by flow cytometry. Addnl., the correlations between the frequencies of the Tfh cells and the levels of autoantibodies and hormones or disease duration were analyzed. The frequency of intrathyroidal CD4⁺CXCR5⁺ICOShigh Tfh cells was higher in HT patients than in GD patients. Significant correlations were identified between the percentages of circulating and intrathyroidal Tfh cells and the serum concentrations of thyroid autoantibodies, especially thyroglobulin antibodies (TgAb), in AITD. Intrathyroidal CD4⁺CXCR5⁺ICOShigh Tfh cells were pos. correlated with free triiodothyronine (FT3) in HT patients but neg. correlated with FT3 in GD patients. In addition, HT patients with a longer disease duration had an increased frequency of intrathyroidal CD4⁺CXCR5⁺ICOShigh and CD4⁺CXCR5⁺PD-1⁺ Tfh cells. In contrast, in the GD patients, a longer disease duration did not affect the frequency of intrathyroidal CD4⁺CXCR5⁺ICOShigh but was associated with a lower frequency of CD4⁺CXCR5⁺PD-1⁺ Tfh cells. Our data suggest that intrathyroidal Tfh cells might play a role in the pathogenesis of AITD and they are potential immunobiomarkers for AITD.

Cantiello, Michela;Carletti, Monica;Giantin, Mery;Gardini, Giulia;Capolongo, Francesca;Cascio, Paolo;Pauletto, Marianna;Girolami, Flavia;Dacasto, Mauro;Nebbia, Carlo research published 《 Induction by Phenobarbital of Phase I and II Xenobiotic-Metabolizing Enzymes in Bovine Liver: An Overall Catalytic and Immunochemical Characterization》, the research content is summarized as follows. In cattle, phenobarbital (PB) upregulates target drug-metabolizing enzyme (DME) mRNA levels. However, few data about PB’s post-transcriptional effects are actually available. This work provides the first, and an almost complete, characterization of PB-dependent changes in DME catalytic activities in bovine liver using common probe substrates and confirmatory immunoblotting investigations. As expected, PB increased the total cytochrome P 450 (CYP) content and the extent of metyrapone binding; moreover, an augmentation of protein amounts and related enzyme activities was observed for known PB targets such as CYP2B, 2C, and 3A, but also CYP2E1. However, contradictory results were obtained for CYP1A, while a decreased catalytic activity was observed for flavin-containing monooxygenases 1 and 3. The barbiturate had no effect on the chosen hydrolytic and conjugative DMEs. For the first time, author also measured the 26S proteasome activity, and the increase observed in PB-treated cattle would suggest this post-translational event might contribute to cattle DME regulation. Overall, this study increased the knowledge of cattle hepatic drug metabolism, and further confirmed the presence of species differences in DME expression and activity between cattle, humans, and rodents. This reinforced the need for an extensive characterization and understanding of comparative mol. mechanisms involved in expression, regulation, and function of DMEs.

Abstract: Brain-body interactions are thought to be essential in emotions but their physiol. basis remains poorly understood. In mice, regular 4 Hz breathing appears during freezing after cue-fear conditioning. Here we show that the olfactory bulb (OB) transmits this rhythm to the dorsomedial prefrontal cortex (dmPFC) where it organizes neural activity. Reduction of the respiratory-related 4 Hz oscillation, via bulbectomy or optogenetic perturbation of the OB, reduces freezing. Behavioral modeling shows that this is due to a specific reduction in freezing maintenance without impacting its initiation, thus dissociating these two phenomena. dmPFC LFP and firing patterns support the region′s specific function in freezing maintenance. In particular, population anal. reveals that network activity tracks 4 Hz power dynamics during freezing and reaches a stable state at 4 Hz peak that lasts until freezing termination. These results provide a potential mechanism and a functional role for bodily feedback in emotions and therefore shed light on the historical James-Cannon debate.

Upon administration, methimazole inhibits the metabolism of iodide and the iodination of tyrosine residues in the thyroid hormone precursor thyroglobulin by TPO; this prevents the synthesis of the thyroid hormones triiodothyronine (T3) and thyroxine (T4).

Methimazole is an antithyroid medication which is now considered the first line agent for medical therapy of hyperthyroidism and Graves disease. Methimazole has been linked to serum aminotransferase elevations during therapy as well as to a clinically apparent, idiosyncratic liver injury that is typically cholestatic and self-limited in course.
Methimazole, also known as tapazole or danantizol, belongs to the class of organic compounds known as imidazolethiones. These are aromatic compounds containing an imidazole ring which bears a thioketone group. Methimazole is a drug which is used for the treatment of hyperthyroidism, goiter, graves disease and psoriasis. Methimazole is soluble (in water) and a very weakly acidic compound (based on its pKa). Methimazole has been detected in multiple biofluids, such as urine and blood. Methimazole can be converted into methimazole S-oxide., 60-56-0.

Imidazole Biochem/physiol Actions: Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division. 60-56-0, formula is C4H6N2S, Name is 1-Methyl-1H-imidazole-2(3H)-thione. It also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes. Name: 1-Methyl-1H-imidazole-2(3H)-thione.

Bakare, Sneha Prasad;Patil, Mahendra research published 《 Thiolate-assisted copper(I) catalyzed C-S cross coupling of thiols with aryl iodides: scope, kinetics and mechanism》, the research content is summarized as follows. An efficient and practical method for the C-S cross coupling of thiophenols with aryl iodides using a Cu(I) catalyst was reported. A diverse set of thiophenols was coupled with electron rich and poor aryl iodides to obtain diaryl sulfides in good to excellent yields. Noteworthily, these reactions proceeded smoothly in polar protic solvents and under ligand-free environments. This procedure also finds application in the synthesis of 2-aminophenyl sulfide derivatives via ring opening of readily available benzothiazole. Furthermore, performed kinetics and computational studies to understand the mechanism of the Cu(I) catalyzed reaction in the absence of a ligand.

Name: 1-Methyl-1H-imidazole-2(3H)-thione, Methimazole is an antithyroid compound found to have antioxidant properties. Methimazole inhibits activation of the IFN-g-induced Janus kinase (JAK)/STAT signaling pathway in FRTL-5 thyroid cells, which may account for its immunodolulatory effects. Additionally, methimazole is an inhibitor of thyroperoxidase.

Methimazole is a thiourea antithyroid agent that prevents iodine organification, thus inhibiting the synthesis of thyroxine. Antihyperthyroid.

Methimazole is an inhibitor of thyroid hormone synthesis. It is a substrate for thyroid peroxidase that traps oxidized iodide, preventing its use by thyroglobulin for thyroid hormone synthesis. Methimazole (0.4 mg/kg) inhibits the absorption of radiolabeled iodide by the thyroid gland in rats by 80.9%.3 It reduces the incidence of lymphocytic thyroiditis in the insulin-dependent type 1 diabetic BB/W rat. Methimazole has been used to induce hypothyroidism in mice. Formulations containing methimazole have been used in the treatment of hyperthyroidism.
