A bcu topol. three-dimensional Mn(II)-organic framework [Mn₂₂(N₃)₈(L)₁₂(H₂O)₂₆·5H₂O]_∞ (1) (L = 1,2,3-triazole-4,5-dicarboxylate) based on an unprecedented nanoscale cage was hydrothermally synthesized. Dominating antiferromagnetic interactions were detected between the Mn^II ions in 1. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Name: 1H-1,2,3-Triazole-4,5-dicarboxylic acid).

1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. Triazoles consist of a five-membered ring containing three nitrogen atoms and are biologically active, especially as antifungal, antimicrobial and enzyme inhibitors. 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.Name: 1H-1,2,3-Triazole-4,5-dicarboxylic acid

Flexible Mixed-Spin Kagome ́Coordination Polymers with Reversible Magnetism Triggered by Dehydration and Rehydration was written by Zhang, Wei-Xiong;Xue, Wei;Chen, Xiao-Ming. And the article was included in Inorganic Chemistry in 2011.COA of Formula: C4H3N3O4 This article mentions the following:

Two new two-dimensional (2D) heterometal coordination polymers [Cu₂M(tzdc)₂(H₂O)₂]·2H₂O [M = Fe²⁺ (1) or Mn²⁺ (2); tzdc^3- = 1,2,3-triazole-4,5-dicarboxylate] were assembled by using the tzdc^3-, Cu²⁺, and Fe²⁺/Mn²⁺ ions. Single-crystal x-ray anal. reveals that the two compounds consist of mixed-spin microporous Kagome layers, which are packed into three-dimensional structures by H bonding and interlayer weak Cu···O interactions. When heated, they can release in a stepwise manner the uncoordinated and coordinated H₂O mols. to produce dehydrated phases (1‘ and 2‘), resp., which are stable up to ∼300°. The structures of 1‘ and 2‘ were determined by powder x-ray diffraction anal., which reveals a change in the coordination sphere of Fe²⁺/Mn²⁺ ions from an octahedron to an elongated 4+2 form, and a microporous-to-nonporous structural transformation involving intralayer wrinkling and interlayer superimposition. When the dehydrated samples are exposed to air, they can return to the hydrated phases quickly by adsorption of H₂O mols. Accordingly, a reversible change in magnetism between the ferrimagnetic character of the hydrated samples and the suppressed ferrimagnetic character of the dehydrated samples was found in this reversible dehydration and rehydration. These facts indicate these 2-dimensional heterometal coordination polymers are unique flexible 2-dimensional dynamic magnetic materials. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6COA of Formula: C4H3N3O4).

An in Vitro Digestion Test That Reflects Rat Intestinal Conditions To Probe the Importance of Formulation Digestion vs First Pass Metabolism in Danazol Bioavailability from Lipid Based Formulations was written by Anby, Mette U.;Nguyen, Tri-Hung;Yeap, Yan Yan;Feeney, Orlagh M.;Williams, Hywel D.;Benameur, Hassan;Pouton, Colin W.;Porter, Christopher J. H.. And the article was included in Molecular Pharmaceutics in 2014.Product Details of 1614-12-6 This article mentions the following:

The impact of gastrointestinal (GI) processing and first pass metabolism on danazol oral bioavailability (BA) was evaluated after administration of self-emulsifying drug delivery systems (SEDDS) in the rat. Danazol absolute BA was determined following oral and intraduodenal (ID) administration of LFCS class IIIA medium chain (MC) formulations at high (SEDDS_H-III) and low (SEDDS_L-III) drug loading and a lipid free LFCS class IV formulation (SEDDS-IV). Experiments were conducted in the presence and absence of ABT (1-aminobenzotriazole) to evaluate the effect of first pass metabolism A series of modified in vitro lipolysis tests were developed to better understand the in vivo processing of SEDDS in the rat. Danazol BA was low (<13%) following oral and ID administration of either SEDDS. Increasing drug loading, ID rather than oral administration, and administration of SEDDS-IV rather than SEDDS-III led to higher oral BA. After pretreatment with ABT, however, danazol oral BA significantly increased (e.g., 60% compared to 2% after administration of SEDDS_L-III), no effect was observed on increasing drug loading, and differences between SEDDS-III and -IV were minimal. In vitro digestion models based on the lower enzyme activity and lower dilution conditions expected in the rat resulted in significantly reduced danazol precipitation from SEDDS-III or SEDDS-IV on initiation of digestion. At the doses administered here (4-8 mg/kg), the primary limitation to danazol oral BA in the rat was first pass metabolism, and the fraction absorbed was >45% after oral administration of SEDDS-III or SEDDS-IV. In contrast, previous studies in dogs suggest that danazol BA is less dependent on first pass metabolism and more sensitive to changes in formulation processing. In vitro digestion models based on likely rat GI conditions suggest less drug precipitation on formulation digestion when compared to equivalent dog models, consistent with the increases in in vivo exposure (fraction absorbed) seen here in ABT-pretreated rats. 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).

And the article was included in CrystEngComm in 2013.Application of 4546-95-6 This article mentions the following:

The hydrothermal reaction of rare earth nitrates, CuCN, 1H-1,2,3-triazole-4,5-dicarboxylic acid (H₃tda), and isonicotinic acid (Hina) resulted in the formation of a new series of 3d-4f heterometallic coordination polymers [LnCu(tda)(ina)₂(H₂O)]·3H₂O (Ln = Eu (1), Tb (2), Gd (3), Dy (4), Ho (5), H₃tda = 1H-1,2,3-triazole-4,5-dicarboxylic acid, Hina = isonicotinic acid). Complexes 1–5 are isostructural and structurally characterized by elemental anal., FT-IR spectroscopy, thermogravimetric anal. (TGA), and single-crystal powder x-ray diffraction (PXRD). Single-crystal x-ray diffraction anal. reveals that the metal cations in these compounds are firstly interconnected by H₃tda ligands to produce a carpet-shaped heterometallic ring [Ln₂(tda)₂Cu₄], and then pillared by bridging Hina mols. to form the 3D layer-pillared porous Ln(III)-Cu(II) heterometallic coordination polymers. In addition, the magnetic properties of 1–5 were also investigated in detail.

Triclosan transformation and impact on an elemental sulfur-driven sulfidogenic process was written by Zhang, Liang;Wu, Dan;Liang, Jialin;Wang, Li;Zhou, Yan. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2021.Product Details of 1614-12-6 This article mentions the following:

Elemental sulfur reduction has recently been demonstrated to be a promising sulfidogenic process for cost-effective treatment of various wastewaters. However, it remains unknown if sulfur reduction is capable of pharmaceuticals and personal care products (PPCPs) removal. Thus, this study investigated the feasibility of such process to remove PPCPs and how PPCPs influence the system performance during a long-term operation. Triclosan (TCS), a typical broad-spectrum antibacterial agent and a ubiquitous emerging organic contaminant in environments was chosen as the model compound Results showed that TCS was removed principally via fast sorption followed by slow biodegradation Amides, polysaccharides and hydroxyl groups in extracellular polymeric substances (EPS) provided adsorption sites. Both metabolism and co-metabolism of TCS with organic carbon removal were responsible for TCS biodegradation Reductive dechlorination and hydroxylation of TCS were inferred during TCS biodegradation The genera Georgenia, Soehngenia, Comamonas, Pseudomonas, Desulfovibrio and Sulfurospirillum were the potential TCS degraders in the sulfur-reducing system. Addnl., the presence of TCS at environmentally relevant concentrations did not neg. impact the performance of organic carbon removal, but altered functional bacteria groups (i.e. fermentative and sulfur-reducing genera). In summary, the sulfur-reducing system could be sufficiently robust to transform organohalide antimicrobials of PPCPs (e.g. triclosan) without compromising the performance. 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).

Evaluation of hepatic damage by reactive metabolites – administration with consideration of circadian variation of murine hepatic glutathione levels – was written by Mori, Koji;Kumano, Atsushi;Kodama, Toshihisa;Takiguchi, Shigeyuki;Takano, Naomi;Kumada, Kohei;Hatao, Kana;Kimura, Takashi. And the article was included in Journal of Toxicological Sciences in 2014.Electric Literature of C6H6N4 This article mentions the following:

Generally, reactive metabolites are detoxified by conjugation with glutathione (GSH). A GSH-depleted model was prepared by administering L-buthionine-(S,R)-sulfoximine (BSO), which can be used to detect hepatic damage by reactive metabolites. However, BSO may cause adverse effects on other organs, such as renal damage by reactive metabolites because it depletes GSH in the whole body. The present study was designed to examine whether it was possible to specifically detect hepatic damage by reactive metabolites without reducing renal GSH levels by administering BSO in a time course when hepatic GSH levels are naturally reduced. Male BALB/c mice were administered reverse osmosis (RO) water or 20 mmol/l BSO in drinking water for 4 days. Subsequently, animals in the RO water group were orally administered 500 mg/kg acetaminophen (APAP) at 9:00 or 15:00 and in the BSO group at 9:00 for 4 days. As a result, severe hepatic damage and necrosis of the renal proximal tubules were observed in the BSO/APAP administration at 9:00 group, and all animals died on 1 or 2 days after APAP administration. Hepatic damage was clearly increased in the RO water/APAP administration at 15:00 group compared with the RO water/APAP administration at 9:00 group. However, renal damage and deaths were not observed This BSO administration model may detect renal damage induced by reactive metabolites. Using an administration time course, whereby hepatic GSH levels were naturally reduced, hepatic damage by reactive metabolites can be detected without secondary renal effects. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6Electric Literature of C6H6N4).

Cytochrome 450 metabolites of arachidonic acid (20-HETE, 11,12-EET and 14,15-EET) promote pheochromocytoma cell growth and tumor associated angiogenesis was written by Cecilia, Colombero;Sofia, Cardenas;Marcela, Venara;Ayelen, Martin;Patricia, Pennisi;Marta, Barontini;Susana, Nowicki. And the article was included in Biochimie in 2020.Reference of 1614-12-6 This article mentions the following:

The importance of cytochrome P 450 (CYP)-derived arachidonic acid (AA) metabolites, 20-hydroxyeicosatetraenoic acid (20-HETE) and epoxyeicosatrienoic acids (EETs) as tumor growth promotors has already been described in several cancer types. The aim of this study was to evaluate the role of these compounds in the biol. of pheochromocytoma/paraganglioma. These tumors originate from chromaffin cells derived from adrenal medulla (pheochromocytomas) or extra-adrenal autonomic paraganglia (paragangliomas), and they represent the most common hereditary endocrine neoplasia. According to mutations in the driver genes, these tumors are divided in two clusters: pseudo-hypoxic and kinase-signaling. EETs, but not 20-HETE, exhibited a potent ability to sustain growth in a murine pheochromocytoma cell line (MPC) in vitro, EETs promoted an increase in cell proliferation and a decrease in cell apoptosis. In a mouse model of pheochromocytoma, the inhibition of CYP-mediated AA metabolism using 1-aminobenzotriazol resulted in slower tumor growth, a decreased vascularization, and a lower final volume Also, the expression of AA-metabolizing CYP monooxygenases was detected in tumor samples from human origin, being their apparent abundance and the production of both metabolites higher in tumors from the kinase-signaling cluster. This is the first evidence of the importance of CYP- derived AA metabolites in the biol. and development of pheochromocytoma/paraganglioma tumors. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6Reference 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. The presence of the three nitrogen atoms in triazole structures afforded opportunities for a plethora of structural modification with the generation of novel therapeutically potential agents, which is different from other heterocyclic compounds.Reference of 1614-12-6
