Multigenerational effects of a complex urban contaminant mixture on the behavior of larval and adult fish in multiple fitness contexts was written by Swank, Ally;Wang, Lina;Ward, Jessica;Schoenfuss, Heiko. And the article was included in Science of the Total Environment in 2021.Reference of 83799-24-0 The following contents are mentioned in the article:

Agricultural and urban storm water runoffs can introduce chems. of emerging concern (CECs) into waterways. These chems. can be continually released, persist, or even accumulate over time, with adverse effects on the physiol. and behavior of aquatic species. Most studies aimed at evaluating the intergenerational effects of CECs have focused exclusively on single chems. By comparison, little is known about the effects of complex CEC mixtures on the behavior of organisms, or how these effects might manifest in subsequent generations. In this study, we exposed three generations of fathead minnows (Pimephales promelas) to environmentally relevant concentrations of a complex CEC mixture representative of urban-impacted waterways and assessed the growth and behavior of larval and adult fish in life-stage-relevant fitness contexts (foraging, boldness, courtship). We found that (i) multigenerational exposure to a complex mixture of CECs altered the behavior of both larvae and adults in different fitness contexts; (ii) concentration-dependent patterns of behavioral impairment were consistent across fitness contexts and life stages; and (iii) the effects of exposure were magnified in the F1 and F2 generations. These results highlight the need for long-term, multigenerational assessments of CECs in affected waterways to robustly inform conservation practices aimed at managing aquatic systems. This study involved multiple reactions and reactants, such as 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0Reference of 83799-24-0).

Pharmacokinetic screening of soluble epoxide hydrolase inhibitors in dogs was written by Tsai, Hsing-Ju;Hwang, Sung Hee;Morisseau, Christophe;Yang, Jun;Jones, Paul D.;Kasagami, Takeo;Kim, In-Hae;Hammock, Bruce D.. And the article was included in European Journal of Pharmaceutical Sciences in 2010.Formula: C16H20F3N3O3 The following contents are mentioned in the article:

Epoxyeicosatrienoic acids that have anti-hypertensive and anti-inflammatory properties are mainly metabolized by soluble epoxide hydrolase (sEH, EC 3.3.2.3). Therefore, sEH has emerged as a therapeutic target for treating various cardiovascular diseases and inflammatory pain. N,N’-Disubstituted ureas are potent sEH inhibitors in vitro. However, in vivo usage of early sEH inhibitors has been limited by their low bioavailability and poor physiochem. properties. Therefore, a group of highly potent compounds with more drug-like physiochem. properties were evaluated by monitoring their plasma profiles in dogs treated orally with sEH inhibitors. Urea compounds with an adamantyl or a 4-trifluoromethoxyphenyl group on one side and a piperidyl or a cyclohexyl ether group on the other side of the urea function showed pharmacokinetic profiles with high plasma concentrations and long half lives. In particular, the inhibitor trans-4-[4-(3-adamantan-1-yl-ureido)-cyclohexyloxy]-benzoic acid (t-AUCB) not only is very potent with good physiochem. properties, but also shows high oral bioavailability for doses ranging from 0.01 to 1 mg/kg. This compound is also very potent against the sEH of several mammals, suggesting that t-AUCB will be an excellent tool to evaluate the biol. of sEH in multiple animal models. Such compounds may also be a valuable lead for the development of veterinary therapeutics. This study involved multiple reactions and reactants, such as 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea (cas: 1222780-33-7Formula: C16H20F3N3O3).

Aryl Hydrocarbon Receptor-Dependent inductions of omega-3 and omega-6 polyunsaturated fatty acid metabolism act inversely on tumor progression was written by Huerta-Yepez, Sara;Tirado-Rodriguez, Ana;Montecillo-Aguado, Mayra R.;Yang, Jun;Hammock, Bruce D.;Hankinson, Oliver. And the article was included in Scientific Reports in 2020.Quality Control of 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea The following contents are mentioned in the article:

Abstract: The Western diet contains a high ratio of omega-6 (ω6) to omega-3 (ω3) polyunsaturated fatty acids (PUFA). The prototypical aryl hydrocarbon receptor (AHR) ligand, 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD), induces CYP1 family enzymes, which can metabolize PUFA to epoxides. Mice fed ω3-rich or ω6-rich diets were treated with TCDD and injected s.c. with AHR-competent Hepa1-GFP hepatoma cells or AHR-deficient LLC lung cancer cells. TCDD reduced the growth rates of the resulting tumors in ω3-fed mice and inhibited their metastasis to the liver and/or lung, but had the opposite effects in mice fed ω6 PUFA. These responses were likely attributable to the corresponding PUFA epoxides generated in tumor cells and/or host, since many depended upon co-administration of a soluble epoxide hydrolase (EPHX2) inhibitor in males, and/or were associated with increases in epoxide levels in tumors and sites of metastasis. Equivalent effects occurred in females in the absence of EPHX2 inhibition, probably because this sex expressed reduced levels of EPHX2. The responses elicited by TCDD were associated with effects on tumor vascularity, tumor cell proliferation and/or apoptosis. Thus environmental AHR agonists, and potentially also endogenous, nutritional, and microbiome-derived agonists, may reduce or enhance cancer progression depending on the composition of dietary PUFA, particularly in females. This study involved multiple reactions and reactants, such as 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea (cas: 1222780-33-7Quality Control of 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea).

Effect of human plasma on hepatic uptake of organic anion-transporting polypeptide 1B substrates: studies using transfected cells and primary human hepatocytes was written by Bi, Yi-an;Ryu, Sangwoo;Tess, David A.;Rodrigues, A. David;Varma, Manthena V. S.. And the article was included in Drug Metabolism & Disposition in 2021.SDS of cas: 83799-24-0 The following contents are mentioned in the article:

Current challenges with the in vitro-in vivo extrapolation (IVIVE) of hepatic uptake clearance involving organic anion-transporting polypeptide (OATP) 1B1/1B3 hinder drug design strategies. Here we evaluated the effect of 100% human plasma on the uptake clearance using transfected human embryonic kidney (HEK) 293 cells and primary human hepatocytes and assessed IVIVE. Apparent unbound uptake clearance (PS_inf,_u) increased significantly (P <0.05) in the presence of plasma (vs. buffer incubations) for about 50% of compounds in both OATP1B1-transfected and wild-type HEK cells. Thus, plasma showed a minimal effect on the uptake ratios. With cultured human hepatocytes, plasma significantly (P < 0.05) increased PSinf,u for 11 of 19 OATP1B substrates (median change of 2.1-fold). Cell accumulation in HEK cells and hepatocytes was also increased for tolbutamide, which is not an OATP substrate. Plasma-to-buffer ratio of P_Sinf,u obtained in hepatocytes showed a good correlation with unbound fraction in plasma, and the relationship was best described by a “facilitated-dissocn” model. IVIVE was evaluated for the 19 OATP1B substrates using hepatocyte data in the presence of buffer and plasma. PS_inf,u from buffer incubations markedly underpredicted hepatic intrinsic clearance (calculated via well stirred and parallel tube models) with an estimated bias of 0.10-0.13.

Comprehensive two-dimensional liquid chromatography as a biomimetic screening platform for pharmacokinetic profiling of compound libraries in early drug development was written by Russo, Giacomo;Grumetto, Lucia;Baert, Mathijs;Lynen, Frederic. And the article was included in Analytica Chimica Acta in 2021.Reference of 83799-24-0 The following contents are mentioned in the article:

A comprehensive two-dimensional liquid chromatog.-based biomimetic platform (LCxLC) has been developed and validated for drug diffusion studies. Human serum albumin (HSA) and immobilized artificial membrane (IAM) were thereby used in the first (1D) and second (2D) separation dimension, resp. While the former was meant to emulate the blood, the latter was instead intended to mimic the intestinal mucosa epithelium. Therefore, the exptl. conditions, i.e. pH, temperature and buffer composition, were modulated to reflect faithfully in vivo conditions. 30 compounds, whose effective intestinal permeability (Peff) assayed in situ on humans by a validated technique was known from the literature, were used as model drugs. A good and orthogonal separation was achieved for the whole dataset, although for a better distribution of the most polar compounds in the elution window a segmented gradient elution program had to be employed. Interestingly, the passively uptaken compounds having the most favorable Peff populated a specific area of the 2D plots, implying that the affinity for HSA and IAM has to lie in specific ranges in order for a compound to be satisfactorily absorbed from the intestinal lumen. Although these results should be regarded as preliminary, this work paves an entirely new and unprecedented way to profile pharmaceutically relevant compounds for their in vivo absorption and distribution potential. This study involved multiple reactions and reactants, such as 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0Reference of 83799-24-0).

A Proposed Quality Control Standard Mixture and Its Uses for Evaluating Nontargeted and Suspect Screening LC/HR-MS Method Performance was written by Knolhoff, Ann M.;Premo, Jacob H.;Fisher, Christine M.. And the article was included in Analytical Chemistry (Washington, DC, United States) in 2021.Safety of 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid The following contents are mentioned in the article:

Nontargeted (NTA) and suspect screening analyses (SSA) aim to detect and identify unknown compounds of interest from a given sample. The complexity and diversity of NTA and SSA methodologies necessitate the use of a comprehensive quality control standard mixture to determine if methods are fit for purpose, but to our knowledge, such a standard has not been developed that can be used by multiple disciplines, nor is one readily available. This work describes the development and anal. of a proposed nontargeted standard/quality control mixture for NTA and SSA applications using liquid chromatog./electrospray ionization-high resolution-mass spectrometry. Considerations in its development included achieving diversity of compounds with respect to elemental composition, mol. weight, retention time, and ionization in pos. and/or neg. ion modes, which resulted in the inclusion of 89 compounds The utility of the standard mixture was applied on our own NTA and SSA workflows where sample preparation efficiency and potential sources of error due to instrumental and data processing methods were evaluated. Some areas in need of improvement were identified, such as hydrophilic compound detection and mol. formula generation for compounds containing fluorine. However, our overall methodol. was found to be fit for purpose and we were able to establish thresholds to increase reliability and throughput of reported results. This study involved multiple reactions and reactants, such as 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0Safety of 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid).

Molecular determinants of the kinetic binding properties of antihistamines at the histamine H₁ receptors was written by Akimoto, Hayato;Uesawa, Yoshihiro;Hishinuma, Shigeru. And the article was included in International Journal of Molecular Sciences in 2021.Related Products of 83799-24-0 The following contents are mentioned in the article:

The binding affinity of ligands for their receptors is determined by their kinetic and thermodn. binding properties. Kinetic analyses of the rate constants of association and dissociation (kon and k_off, resp.) of antihistamines have suggested that second-generation antihistamines have a long duration of action owing to the long residence time (1/k_off) at the H1 receptors. In this study, we examined the relationship between the kinetic and thermodn. binding properties of antihistamines, followed by an evaluation of the structural determinants responsible for their kinetic binding properties using quant. structure-activity relationship (QSAR) analyses. We found that whereas the binding enthalpy and entropy might contribute to the increase and decrease, relationship in the k_off values, there was no significant relationship with the k_on values. QSAR analyses indicated that kon and koff values could bedetd. by the descriptors FASA_H (water-accessible surface area of all hydrophobic atoms divided by total water-accessible surface area) and vsurf_CW2 (a 3D mol. field descriptor weighted by capacity factor 2, the ratio of the hydrophilic surface to the total mol. surface), resp. These findings provide further insight into the mechanisms by which the kinetic binding properties of antihistamines are regulated by their thermodn. binding forces and physicochem. properties.
