Metabolic Activation of Cholestatic Drug-Induced Bile Acid-Dependent Toxicity in Human Sandwich-Cultured Hepatocytes was written by Ogimura, Eiichiro;Tokizono, Mayuko;Sekine, Shuichi;Nakagawa, Tetsuya;Bando, Kiyoko;Ito, Kousei. And the article was included in Journal of Pharmaceutical Sciences in 2017.Name: 1H-Benzo[d][1,2,3]triazol-1-amine This article mentions the following:

We previously reported a cell-based toxicity assay using sandwich-cultured hepatocytes in combination with a titrated amount of human bile acid (BA) species. In this assay, test compound-induced inhibition of BA efflux from sandwich-cultured hepatocytes leads to BA-dependent cell toxicity (BA_tox, i.e., cell death due to the accumulation of BAs). Using this assay, we investigated whether 1-aminobenzotriazole (1-ABT; a nonselective cytochrome P 450 inhibitor) enhanced or suppressed test compound-induced BA_tox. There was a tendency that BA_tox of many compounds was enhanced by 1-ABT in human hepatocytes; in contrast, such a tendency was not observed in rat hepatocytes. In particular, 1-ABT tended to enhance BA_tox of several compounds (clopidogrel, ticlopidine, everolimus, etc.) in human, whereas 1-ABT tended to enhance BA_tox of only ticlopidine in rat. These results indicate that this system can be used to evaluate BA_tox while taking into account drug metabolism and the existence of an interspecies difference in the effect of 1-ABT treatment on BA_tox. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6Name: 1H-Benzo[d][1,2,3]triazol-1-amine).

1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) 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. 1,2,3-Triazoles are usually prepared following (3+2) cycloaddition protocols. A common technique for unsubstituted triazoles is the Huisgen azide-alkyne 1,3-dipolar cycloaddition: a azide and an alkyne react at high temperature to form a ring. However, the Huisgen strategy produces a mixture of isomers (typically 1,4- and 1,5-disubstituted) when used to produce substituted triazoles.Computed Properties of C4H3N3O4

Salicylic Acid Enhances Adventitious Root and Aerenchyma Formation in Wheat under Waterlogged Conditions was written by Koramutla, Murali Krishna;Tuan, Pham Anh;Ayele, Belay T.. And the article was included in International Journal of Molecular Sciences in 2022.Quality Control of 1H-Benzo[d][1,2,3]triazol-1-amine This article mentions the following:

The present study investigated the role of salicylic acid (SA) in regulating morpho-anatomical adaptive responses of a wheat plant to waterlogging. Our pharmacol. study showed that treatment of waterlogged wheat plants with exogenous SA promotes the formation axile roots and surface adventitious roots that originate from basal stem nodes, but inhibits their elongation, leading to the formation of a shallow root system. The treatment also enhanced axile root formation in non-waterlogged plants but with only slight reductions in their length and branch root formation. Exogenous SA enhanced the formation of root aerenchyma, a key anatomical adaptive response of plants to waterlogging. Consistent with these results, waterlogging enhanced SA content in the root via expression of specific isochorismate synthase (ICS; ICS1 and ICS2) and phenylalanine ammonia lyase (PAL; PAL4, PAL5 and PAL6) genes and in the stem nodes via expression of specific PAL (PAL5 and PAL6) genes. Although not to the same level observed in waterlogged plants, exogenous SA also induced aerenchyma formation in non-waterlogged plants. The findings of this study furthermore indicated that inhibition of ethylene synthesis in SA treated non-waterlogged and waterlogged plants does not have any effect on SA-induced emergence of axile and/or surface adventitious roots but represses SA-mediated induction of aerenchyma formation. These results highlight that the role of SA in promoting the development of axile and surface adventitious roots in waterlogged wheat plants is ethylene independent while the induction of aerenchyma formation by SA requires the presence of ethylene.

And the article was included in Journal of Environmental Management in 2016.Related Products of 1614-12-6 This article mentions the following:

The efficiency of two white-rot fungi (WRF), Trametes versicolor and Ganoderma lucidum, to eliminate thirteen pharmaceutical pollutants with concomitant biodiesel production from the accumulating lipid content after treatment, was examined The removal efficiency was studied using both individual and combined strains. The results of individual and combined strains showed a total removal (100%) of diclofenac (DCF), gemfibrozil (GFZ), ibuprofen (IBP), progesterone (PGT) and ranitidine (RNT). Lower removals were achieved for 4-acetamidoantipyrin (AAA), clofibric acid (ACF), atenolol (ATN), caffeine (CFN), carbamazepine (CZP), hydrochlorothiazide (HCT), sulfamethoxazole (SMX) and sulpiride (SPD), although the combination of both strains enhanced the systems efficiency, with removals ranging from 15 to 41%. This increase of the removal efficiency when combining both strains was attributed to the interactions developed between them (i.e., competition). Results from enzymic and cytochrome P 450 examination suggested that both extracellular (laccase, MnP, LiP) and intracellular oxidation mechanisms participate in the biol. removal of pharmaceuticals. This catalytic system provided conversions close to 80% of the saponifiable fraction (including free fatty acids and glycerides) in the presence of high amount of impurities. The overall weight FAME yield, based on the initial dried mass, was close to 30% for both strains.

Preliminary characterization of a murine model for 1-bromopropane neurotoxicity: Role of cytochrome P450 was written by Zong, Cai;Garner, C. Edwin;Huang, Chinyen;Zhang, Xiao;Zhang, Lingyi;Chang, Jie;Toyokuni, Shinya;Ito, Hidenori;Kato, Masashi;Sakurai, Toshihiro;Ichihara, Sahoko;Ichihara, Gaku. And the article was included in Toxicology Letters in 2016.Recommanded Product: 1614-12-6 This article mentions the following:

Neurotoxicity of 1-bromopropane (1-BP) has been reported in both human cases and animal studies. To date, neurotoxicity of 1-BP has been induced in rats but not in mice due to the lethal hepatotoxicity of 1-BP. Oxidization by cytochromes P 450 and conjugation with glutathione (GSH) are two critical metabolism pathways of 1-BP and play important roles in toxicity of 1-BP. The aim of the present study was to establish a murine model of 1-BP neurotoxicity, by reducing the hepatotoxicity of 1-BP with 1-aminobenzotriazole (1-ABT); a commonly used nonspecific P 450s inhibitor. The results showed that s.c. or i.p. injection of 1-ABT at 50 mg/kg body weight BID (100 mg/kg BW/day) for 3 days, inhibited about 92-96% of hepatic microsomal CYP2E1 activity, but only inhibited about 62-64% of CYP2E1 activity in brain microsomes. Mice treated with 1-ABT survived even after exposure to 1200 ppm 1-BP for 4 wk and histopathol. studies showed that treatment with 1-ABT protected mice from 1-BP-induced hepatic necrosis, hepatocyte degeneration, and hemorrhage. After 4-wk exposure to 1-BP, the brain weight of 1-ABT(+)/1200 ppm 1-BP group was decreased significantly. In 1-ABT-treated groups, expression of hippocampal Ran protein and cerebral cortical GRP78 was dose-dependently increased by exposure to 1-BP. The authors conclude that the control of hepatic P 450 activity allows the observation of effects of 1-BP on the murine brain at a higher concentration by reduction of hepatotoxicity. The study suggests that further experiments with liver-specific control of P 450 activity using gene technol. might provide better murine models for 1-bromopropane-induced neurotoxicity.

And the article was included in Journal of the American Society of Nephrology in 2020.Synthetic Route of C6H6N4 This article mentions the following:

Ferroptosis-causing radicals that are targeted by ferroptosis suppressors have not been unequivocally identified. Methods Using cell-based assay, we screened cytochrome P 450 substrate compounds to identify drugs with antiferroptotic activity and investigated the underlying mechanism. To evaluate radical-scavenging activity, we used ESR-spin trapping methods and a fluorescence probe for lipid radicals, NBD-Pen, that we had developed. Results We identified various US Food and Drug Administration-approved drugs and hormones that have antiferroptotic properties, including rifampicin, promethazine, omeprazole, indole-3-carbinol, carvedilol, propranolol, estradiol, and thyroid hormones. The antiferroptotic drug effects were closely associated with scavenging of lipid peroxyl radicals but not significantly related to interactions with other radicals. The elevated lipid peroxyl radical levels were associated with ferroptosis onset, and known ferroptosis suppressors, such as ferrostatin-1, also functioned as lipid peroxyl radical scavengers. The drugs exerted antiferroptotic activities in various cell types, including tubules, podocytes, and renal fibroblasts. Moreover, in mice, drugs ameliorated AKI and liver injury, with suppression of tissue lipid peroxidation and decreased cell death. Conclusions Although elevated lipid peroxyl radical levels can trigger ferroptosis onset, some drugs that scavenge lipid peroxyl radicals can help control ferroptosis-related disorders, including AKI.
