The aim of the present study was to characterize the mol. mechanisms of 1,2-DCP-induced hepatotoxic effects by proteomic anal. We analyzed quant. the differential expression of proteins in the mouse liver and investigated the role of P 450 in mediating the effects of 1,2-DCP. Male C57BL/6JJcl mice were exposed to 0, 50, 250, or 1250 ppm 1,2-DCP and treated with either 1-aminobenzotriazole (1-ABT), a nonselective P 450 inhibitor, or saline, for 8 h/day for 4 wk. Two-dimensional difference in gel electrophoresis (2D-DIGE) combined with matrix-assisted laser-desorption ionization time-of-flight mass spectrometry (MALDI-TOF/TOF/MS) was used to detect and identify proteins affected by the treatment. PANTHER overrepresentation test on the identified proteins was conducted. 2D-DIGE detected 61 spots with significantly different intensity between 0 and 250 ppm 1,2-DCP groups. Linear regression anal. showed significant trend with 1,2-DCP level in 17 proteins in mice co-treated with 1-ABT. 1-ABT mitigated the differential expression of these proteins. The gene ontol. enrichment anal. showed overrepresentation of proteins functionally related to nickel cation binding, carboxylic ester hydrolase activity, and catalytic activity. The results demonstrated that exposure to 1,2-DCP altered the expression of proteins related with catalytic and carboxylic ester hydrolase activities, and that such effect was mediated by P 450 enzymic activity. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6Product Details of 1614-12-6).

1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6) belongs to triazole derivatives. Triazoles exhibit substantial isomerism, depending on the positioning of the nitrogen atoms within the ring.

Two mechanisms provide tolerance to cyhalofop-butyl in pond lovegrass [Eragrostis japonica (Thunb.) Trin.] was written by Liu, Ying;Wang, Hao;Gao, Haitao;Zhu, Guangtao;Peng, Zhen;Li, Jun;Dong, Liyao. And the article was included in Pesticide Biochemistry and Physiology in 2022.Electric Literature of C6H6N4 This article mentions the following:

Pond lovegrass [Eragrostis japonica (Thunb.) Trin.] is an annual grass weed of rice fields worldwide. Cyhalofop-Bu has been widely used for controlling annual grass weeds in rice fields. However, E. japonica is tolerant to cyhalofop-Bu. The ED values of cyhalofop-Bu for 29 E. japonica populations causing 50% inhibition of fresh weight (GR50: 130.15 to 187.61 g a.i. ha^-1) were much higher than the recommended dose of cyhalofop-Bu (75 g a.i. ha^-1) in the field. The mechanisms of tolerance to cyhalofop-Bu in E. japonica were identified. In vitro activity assays revealed that the cyhalofop-Bu concentration required to inhibit 50% of the acetyl-CoA carboxylase (ACCase) activity (IC₅₀) was 6.22-fold higher in E. japonica than that in the cyhalofop-butyl-susceptible Chinese sprangletop [Leptochloa chinensis (L.) Nees]. However, mutations in the ACCase gene, previously found to endow target-site resistance in weeds, were not detected in the sequences obtained. Addnl., the expression level of genes encoding ACCase in E. japonica was found to be as similar to L. chinensis. Tolerance was reduced by two cytochrome P 450 monooxygenases (Cyt P450s) inhibitors (1-aminobenzotriazole and piperonyl butoxide) and the activity of NADPH-dependent cytochrome P 450 reductase in E. japonica was approx. 4.46-fold higher than that of L. chinensis after cyhalofop-Bu treatment. Taken together, it is concluded that two co-existing mechanisms, an insensitive target ACCase and an enhanced metabolism mediated by Cyt P450s, endow tolerance to cyhalofop-Bu in E. japonica.

The separation of xenon/krypton (Xe/Kr) mixtures plays a vital role in the industrial process of manufacturing high-purity xenon. Compared with energy-intensive cryogenic distillation, porous materials based on phys. adsorption are very promising in the low-cost and energy-saving separation processes. Herein, we show that a cationic metal-organic framework (named as FJU-55) exhibits highly efficient Xe/Kr separation performance, which can be attributable to its uniform three-dimensional (3D) interconnection channels and the electro-pos. features as the host framework. Moreover, FJU-55 demonstrates good Xe adsorption capacity of 1.41 mmol/g and excellent Xe/Kr selectivity of 10 (298 K and 100 kPa), together with a high Qst value of 39.4 kJ/mol at low coverage area. The superior Xe/Kr separation performance of FJU-55 was further confirmed by the dynamic breakthrough experiments Results obtained via mol. modeling studies have revealed that the suitable pore size and abundant accessible aromatic ligands in FJU-55 could offer strong multiple C-H^..Xe interactions, which play a collaborative role in this challenging gas separation task.

Fimasartan (FMS), an angiotensin II receptor antagonist, is metabolized to FMS S-oxide, FMS N-glucuronide, oxidative desulfurized FMS (BR-A-557), and hydroxy-Bu FMSs. The purpose of this study was to characterize enzymes involved in NADPH-dependent FMS metabolism using recombinant enzymes such as cytochrome P 450 (CYP) and flavin-containing monooxygenase (FMO), as well as selective chem. inhibitors. The results showed that CYP, but not FMO, plays a major role in FMS metabolism CYP2C9, CYP3A4, and CYP3A5 were involved in the formation of FMS S-oxide, which was further metabolized to BR-A-557 by CYP3A4/5. CYP2C9 played an exclusive role in Bu hydroxylation. The specificity constant (kcat/Km) values for S-oxidation by CYP2C9, CYP3A4, and CYP3A5 were 0.21, 0.34, and 0.19μM-1•min-1, resp. The kcat/Km values of hydroxylation at the 1-, 2-/3-, and 4-Bu group in CYP2C9 were 0.0076, 0.041, and 0.035μM-1•min-1, resp. The kcat and Km values provide information for the prediction of FMS metabolism in vivo. In addition, simultaneous determination of the FMS metabolites may be used to evaluate CYP2C9 and CYP3A4/5 activity.

Detection of metabolic activation leading to drug-induced phospholipidosis in rat hepatocyte spheroids was written by Takagi, Masashi;Sanoh, Seigo;Santoh, Masataka;Ejiri, Yoko;Kotake, Yaichiro;Ohta, Shigeru. And the article was included in Journal of Toxicological Sciences in 2016.Category: triazoles This article mentions the following:

Drug-induced phospholipidosis (PLD) is one of the adverse reactions to treatment with cationic amphiphilic drugs. Recently, simple and reliable evaluation methods for PLD have been reported. However, the predictive power of these methods for in vivo PLD induction is insufficient in some cases. To accurately predict PLD, we focused on drug metabolism and used three-dimensional cultures of hepatocytes known as spheroids. Here we used the fluorescent phospholipid dye N-(7-nitrobenz-2-oxa-1,3-diazol-4-y1)-1,2-dihexadecanoyl-sn-glycero-3-phosphoethanolamine (NBD-PE) to detect PLD induction. After 48 h exposure to 20 uM amiodarone and amitriptyline, PLD inducers. NBD-PE fluorescence in the spheroids was significantly higher than that in the control. In contrast, 1 niM acetaminophen, as a neg. control, did not increase fluorescence. Furthermore, the combination of NBD-PE fluorescence and LysoTracker Red fluorescence and the accumulation of intrinsic phospholipids reflected PLD induction in spheroids. To evaluate metabolic activation, we assessed PLD induction by loratadine. NBD-PE fluorescence intensity was significantly increased by 50 μM loratadine treatment. However, the fluorescence was markedly decreased by co-treatment with 500 μM 1-aminobenzotriazole, a broad eytochrome P 450 inhibitor. The formation of desloratadine, a metabolite of loratadine, was observed in spheroids after treatment with loratadine alone. These results showed that metabolic activation is the key factor in PLD induction by treatment with loratadine. We demonstrated that rat primary hepatocyte spheroid culture is a useful model for evaluating drug-induced PLD induction mediated by metabolic activation of the drug using the fluorescence probe technique. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6Category: triazoles).

1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6) belongs to triazole derivatives. However, triazoles are also useful in bioorthogonal chemistry, because the large number of nitrogen atoms causes triazoles to react similar to azides.
