The epoxyeicosatrienoic acid (EET) exerts beneficial effects on insulin resistance and/or hypertension. EETs could be readily converted to less biol. active diols by soluble epoxide hydrolase (sEH). However, whether sEH inhibition can ameliorate the comorbidities of insulin resistance and hypertension and the underlying mechanisms of this relationship are unclear. In this study, C57BL/6 mice were rendered hypertensive and insulin resistant through a high-fat and high-salt (HF-HS) diet. The sEH inhibitor, 1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea (TPPU), was used to treat mice (1 mg/kg/day) for 8 wk, followed by anal. of metabolic parameters. The expression of sEH and the sodium-glucose cotransporter 2 (SGLT2) was markedly upregulated in the kidneys of mice fed an HF-HS diet. We found that TPPU administration increased kidney EET levels, improved insulin resistance, and reduced hypertension. Furthermore, TPPU treatment prevented upregulation of SGLT2 and the associated increased urine volume and the excretion of urine glucose and urine sodium. Importantly, TPPU alleviated renal inflammation. In vitro, human renal proximal tubule epithelial cells (HK-2 cells) were used to further investigate the underlying mechanism. We observed that 14,15-EET or sEH knockdown or inhibition prevented the upregulation of SGLT2 upon treatment with palmitic acid or NaCl by inhibiting the inhibitory kappa B kinase α/β/NF-κB signaling pathway. In conclusion, sEH inhibition by TPPU alleviated insulin resistance and hypertension induced by an HF-HS diet in mice. The increased urine excretion of glucose and sodium was mediated by decreased renal SGLT2 expression because of inactivation of the inhibitory kappa B kinase α/β/NF-κB-induced inflammatory response. This study involved multiple reactions and reactants, such as 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea (cas: 1222780-33-7Formula: C16H20F3N3O3).

1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea (cas: 1222780-33-7) belongs to piperidine derivatives. The piperidine structural motif is present in numerous natural alkaloids. These include piperine, which gives black pepper its spicy taste. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol.Formula: C16H20F3N3O3

Epoxyeicosatrienoic acids (EETs) have anti-inflammatory effects and soluble epoxide hydrolase (sEH) inhibition might be a useful therapeutic approach to manage inflammatory disorders. The purpose of the study was to investigate whether nucleotide-binding and oligomerization domain-like receptor (NLR) C4 inflammasome-related pro-inflammatory and anti-inflammatory signaling pathways in the central nervous system (CNS) participates in the effect of trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl)urea (TPPU), a potent sEH inhibitor, to prevent hyperalgesia in the LPS-induced pain mouse model. The latency of pain within 30 s was measured by the hot plate test in male mice injected with saline, lipopolysaccharide (LPS) (10 mg/kg), and/or TPPU (0.3, 0.5, or 1 mg/kg) after 6 h. Hyperalgesia induced by LPS was associated with decreased 14,15-dihydroxyeicosatrienoic acid and interleukin (IL)-1β levels and enhanced expression of NLRC4, apoptosis-associated speck-like protein containing a caspase activation and recruitment domain (ASC), caspase-1 p20, IL-1β, and caspase-11 p20 in the brains and spinal cords of the animals. Besides the increased expression of NADP oxidase (NOX) subunits (gp91^phox and p47^phox) and nitrotyrosine, a decrease in NLRC3, inducible nitric oxide synthase (iNOS), and neuronal NOS (nNOS) expression was also observed in the tissues of LPS-treated mice. TPPU at 0.5 mg/kg dose prevented the changes induced by LPS. Likely, decreased activity of pro-inflammatory NLRC4/ASC/pro-caspase-1 and caspase-11 inflammasomes and NOX in addition to enhanced levels of anti-inflammatory EETs and expression of NLRC3, iNOS, and nNOS in the CNS of mice participates in the protective effect of TPPU against LPS-induced hyperalgesia.

Suppression of inflammation and fibrosis using soluble epoxide hydrolase inhibitors enhances cardiac stem cell-based therapy was written by Sirish, Padmini;Thai, Phung N.;Lee, Jeong Han;Yang, Jun;Zhang, Xiao-Dong;Ren, Lu;Li, Ning;Timofeyev, Valeriy;Lee, Kin Sing Stephen;Nader, Carol E.;Rowland, Douglas J.;Yechikov, Sergey;Ganaga, Svetlana;Young, Nilas;Lieu, Deborah K.;Yamoah, Ebenezer N.;Hammock, Bruce D.;Chiamvimonvat, Nipavan.

Stem cell replacement offers a great potential for cardiac regenerative therapy. However, one of the critical barriers to stem cell therapy is a significant loss of transplanted stem cells from ischemia and inflammation in the host environment. Here, we tested the hypothesis that inhibition of the soluble epoxide hydrolase (sEH) enzyme using sEH inhibitors (sEHIs) to decrease inflammation and fibrosis in the host myocardium may increase the survival of the transplanted human induced pluripotent stem cell derived-cardiomyocytes (hiPSC-CMs) in a murine postmyocardial infarction model. A specific sEHI (1-trifluoromethoxyphenyl-3-(1-propionylpiperidine-4-yl)urea [TPPU]) and CRISPR/Cas9 gene editing were used to test the hypothesis. TPPU results in a significant increase in the retention of transplanted cells compared with cell treatment alone. The increase in the retention of hiPSC-CMs translates into an improvement in the fractional shortening and a decrease in adverse remodeling. Mechanistically, we demonstrate a significant decrease in oxidative stress and apoptosis not only in transplanted hiPSC-CMs but also in the host environment. CRISPR/Cas9-mediated gene silencing of the sEH enzyme reduces cleaved caspase-3 in hiPSC-CMs challenged with angiotensin II, suggesting that knockdown of the sEH enzyme protects the hiPSC-CMs from undergoing apoptosis. Our findings demonstrate that suppression of inflammation and fibrosis using an sEHI represents a promising adjuvant to cardiac stem cell-based therapy. Very little is known regarding the role of this class of compounds in stem cell-based therapy. There is consequently an enormous opportunity to uncover a potentially powerful class of compounds, which may be used effectively in the clin. setting.

Gene deficiency and pharmacological inhibition of soluble epoxide hydrolase confers resilience to repeated social defeat stress was written by Ren, Qian;Ma, Min;Ishima, Tamaki;Morisseau, Christophe;Yang, Jun;Wagner, Karen M.;Zhang, Ji-chun;Yang, Chun;Yao, Wei;Dong, Chao;Han, Mei;Hammock, Bruce D.;Hashimoto, Kenji.

Depression is a severe and chronic psychiatric disease, affecting 350 million subjects worldwide. Although multiple antidepressants have been used in the treatment of depressive symptoms, their beneficial effects are limited. The soluble epoxide hydrolase (sEH) plays a key role in the inflammation that is involved in depression. Thus, the authors examined here the role of sEH in depression. In both inflammation and social defeat stress models of depression, a potent sEH inhibitor, TPPU, displayed rapid antidepressant effects. Expression of sEH protein in the brain from chronically stressed (susceptible) mice was higher than of control mice. Furthermore, expression of sEH protein in postmortem brain samples of patients with psychiatric diseases, including depression, bipolar disorder, and schizophrenia, was higher than controls. This finding suggests that increased sEH levels might be involved in the pathogenesis of certain psychiatric diseases. In support of this hypothesis, pretreatment with TPPU prevented the onset of depression-like behaviors after inflammation or repeated social defeat stress. Moreover, sEH KO mice did not show depression-like behavior after repeated social defeat stress, suggesting stress resilience. The sEH KO mice showed increased brain-derived neurotrophic factor (BDNF) and phosphorylation of its receptor TrkB in the prefrontal cortex, hippocampus, but not nucleus accumbens, suggesting that increased BDNF-TrkB signaling in the prefrontal cortex and hippocampus confer stress resilience. All of these findings suggest that sEH plays a key role in the pathophysiol. of depression, and that epoxy fatty acids, their mimics, as well as sEH inhibitors could be potential therapeutic or prophylactic drugs for depression.

Urban wastewaters (WW) are a major vector of many emerging pollutants (EPs) to aquatic ecosystems, as urban wastewater treatment plants (WWTPs) are not designed to abate them. New methods are now critically necessary for a more comprehensive anal. of WW samples and for the assessment of the WWTP efficiency in EP removal. To this end, the present study aims to develop a methodol. to identify and quantify EPs, especially pharmaceutical residues and pesticides, in the raw and treated wastewater of 10 heterogeneous WWTPs in a highly urbanized territory in France over three sampling campaigns, through the following steps: (1) development and implementation of a suspect screening of EPs in WW samples, based on a solid phase extraction followed by an LC-QToF-MS anal.; (2) confirmation of their identification by reinjection of WW samples spiked with authentic anal. standards; (3) quantification of previously identified compounds by targeted LC-QToF-MS anal. in raw and treated effluents and assessment of their removal efficiency by WWTPs. Forty-one EPs, including 37 pharmaceutical residues (such as anti-depressive, anti-hypertensive, or antipsychotic drugs) and 4 pesticides, were identified by suspect screening. Some of them (e.g. milnacipran) are reported for the first time in urban WWTPs in this study. High variability in detection frequency and concentrations were observed in function of the EP and WWTP. Nevertheless, median removal rates were considered neg. or low for more than 50% of the EPs (resp. 4 and 17), leading to a quantification of significant concentrations in treated WW. Their release into receiving streams may thus lead to ecotoxicol. risks that should be evaluated in order to prevent any degradation of the exposed ecosystems.

To investigate the influence of a cytochrome P 450 CYP3A4 and efflux transporter P-glycoprotein (P-gp) inducing Hypericum perforatum extract on the pharmacokinetics and pharmacodynamics of rivaroxaban. Open-label, nonrandomized, sequential treatment interaction study. Following CYP3A4 and P-gp phenotyping using low-dose midazolam and fexofenadine, 12 healthy volunteers received a single oral dose of 20 mg rivaroxaban and rivaroxaban plasma concentrations and inhibition of the activated coagulation factor X (factor Xa) activity were measured prior to and up to 48 h postdosing. The procedures were repeated after 2 wk’ treatment with the H. perforatum extract The geometric mean ratios for the area under the concentration-time curve and Cmax of rivaroxaban after/before induction with the H. perforatum extract were 0.76 (90% confidence interval [CI] 0.70, 0.82) and 0.86 (90% CI 0.76, 0.97), resp. Inhibition of factor Xa activity was reduced with a geometric mean area under the effect-time curve ratio after/before induction of 0.80 (90% CI 0.71, 0.89). No clin. significant differences were found regarding Tmax (median 1.5 vs 1 h, P = .26) and terminal elimination half-life (mean 10.6 vs 10.8 h, P = .93) of rivaroxaban. The H. perforatum extract significantly induced CYP3A4 and P-gp activity, as evidenced by phenotyping. The CYP3A4/P-gp inducing H. perforatum extract caused a decrease of rivaroxaban exposure with a proportional decrease of the pharmacodynamic effect. Although the data do not justify a contraindication for the combination or a systematic adjustment of rivaroxaban dosage, avoidance of the combination or laboratory monitoring should be considered in patients taking hyperforin-containing H. perforatum extracts with rivaroxaban.

Previously, we have identified a highly potent CXCR4 antagonist 2 [cyclo(-D-Tyr¹-Arg²-Arg³-Nal⁴-Gly⁵-)] and its Arg² epimer 3 [cyclo(-D-Tyr¹–D-Arg²-Arg³-Nal⁴-Gly⁵-)] by the screening of cyclic pentapeptide libraries that were designed based on the structure-activity relationship studies on 14-residue peptidic CXCR4 antagonist 1. In the present study, a new series of analogs of 2 and 3 were synthesized to evaluate the influences of peptide side-chain and backbone modification on bioactivities. Based on the Ala-scanning study, in which each residue in 2 and 3 was replaced with Ala having the identical chirality, substitution of Arg³ and Nal⁴ [Nal = L-3-(2-naphthyl)alanine] with Ala (compounds 6, 7, 10, 11) led to significant loss of the potency, indicating these amino acids are more important contributors to the bioactivity. For the cyclic peptide backbone, several modifications including D/L-Ala or cyclic amino acids substitution at the Gly⁵ position and sequential N-methylation on amide nitrogens were conducted. Among the analogs, compounds 13 [cyclo(-D-Tyr¹-Arg²-Arg³-Nal⁴–D-Ala⁵-)] and 32 [cyclo(-D-Tyr¹–D-MeArg²-Arg³-Nal⁴-Gly⁵-)] were close in potency to the most potent lead 2. NMR and conformational anal. indicated that both of these analogs favor the same backbone conformation as 2, whereas similar anal. of less potent analogs indicates that an altered backbone conformation is favored. The conformational anal. showed that steric repulsion by a 1,3-allylic strain-like effect across the planar peptide bond might contribute to the conformational preferences of cyclic pentapeptides.

Breviscapine (BRE) is usually used for long-term use in patients with cardiovascular diseases such as coronary heart disease, angina pectoris, and cerebral thrombosis. It is possible to combine it with P-glycoprotein (P-gp) substrates in clinic. At present, little is known about whether the simultaneous use of BRE affects the disposal of P-gp substrates. The aim of this study was to evaluate the effect of BRE on the pharmacokinetics of fexofenadine (FEX), a P-gp probe substrate and its associations with the MDR1 C3435T genetic polymorphism in healthy volunteers. In this randomised, open-label, placebo-controlled, two-phase crossover clin. study, drug interactions were evaluated in healthy volunteers. FEX was used as a phenotypic probe for P-gp. In each phase, 18 volunteers were given daily doses of 120 mg (40 mg, three times a day) of BRE tablet or a placebo for 14 days. On day 15, a single oral dose of 120 mg FEX hydrochloride was given orally. Blood samples were collected at predefined time intervals, and plasma levels of FEX were determined by ultra-high performance liquid chromatog.-tandem mass spectrometry (UHPLC-MS/MS). The pharmacokinetic parameters were calculated by non-compartmental method, and bioequivalence was evaluated. Results showed that BRE pretreatment did not significantly affect the pharmacokinetics of FEX. The peak maximum plasma concentration (Cmax) and the area under the plasma concentration-time curve from zero to infinity (AUCinf) mean value of FEX with BRE and placebo-treated groups were 699 ng/mL vs. 710 ng/mL and 2972.5 ng·h/mL vs. 3460.5 ng·h/mL, resp. The geometric mean ratios (90% confidence intervals) for FEX Cmax and AUCinf were within the pre-specified range of 0.8-1.25, indicating that FEX in the two pretreatment phases were bioequivalent. Pharmacokinetic parameters of FEX showed no statistically significant difference between MDR1 C3435T CC, CT and TT genotype, revealing that BRE and MDR1 C3435T gene polymorphisms did not affect the pharmacokinetics of FEX in healthy volunteers.

Biotransformation of Chemicals at the Water-Sediment Interface-Toward a Robust Simulation Study Setup was written by Seller, Carolin;Ozel Duygan, Birge D.;Honti, Mark;Fenner, Kathrin.

Studying aquatic biotransformation of chems. in laboratory experiments, i.e., OECD 308 and OECD 309 studies, is required by international regulatory frameworks to prevent the release of persistent chems. into natural water bodies. Here, we aimed to address several previously described shortcomings of OECD 308/309 studies regarding their variable outcomes and questionable environmental relevance by broadly testing and characterizing a modified biotransformation test system in which an aerated water column covers a thin sediment layer. Compared to standard OECD 308/309 studies, the modified system showed little inter-replicate variability, improved observability of biotransformation, and consistency with first-order biotransformation kinetics for the majority of 43 test compounds, including pharmaceuticals, pesticides, and artificial sweeteners. To elucidate the factors underlying the decreased inter-replicate variability compared to OECD 309 outcomes, we used multidimensional flow cytometry data and a machine learning-based cell type assignment pipeline to study cell densities and cell type diversities in the sediment and water compartments. Our here presented data on cell type composition in both water and sediment allows, for the first time, to study the behavior of microbial test communities throughout different biotransformation simulation studies. We found that sediment-associated microbial communities were generally more stable throughout the experiments and exhibited higher cell type diversity than the water column-associated communities. Consistently, our data indicate that aquatic biotransformation of chems. can be most robustly studied in test systems providing a sufficient amount of sediment-borne biomass. While these findings favor OECD 308-type systems over OECD 309-type systems to study biotransformation at the water-sediment interface, our results suggest that the former should be modified toward lower sediment-water ratios to improve observability and interpretability of biotransformation.
