BACKGROUND & AIMS: Acetaminophen (APAP)-induced liver injury is one of the most common causes of acute liver failure, however, a dear definition of sensitizing risk factors is lacking. Here, we investigated the role of the ligand-activated transcription factor aryl hydrocarbon receptor (Ahr) in APAP-induced liver injury. We hypothesized that Ahr, which integrates environmental, dietary, microbial and metabolic signals into complex cellular transcriptional programs, might act as a rheostat for APAP-toxicity. METHODS: Wildtype or conditional Ahr knockout mice lacking Ahr in hepatocytes (Alb(Delta/Delta Ahr)) or myeloid cells (LysM(Delta/Delta Ahr)) were treated with the specific Ahr ligand 2-(1’H-indole-3′-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE) together with APAP. RESULTS: Ahr activation by ITE, which by itself was non-toxic, exacerbated APAP-induced hepatotoxicity compared to vehicle-treated controls, causing 80% vs. 0% mortality after administration of a normally sublethal APAP overdose. Of note, Ahr activation induced hepatocyte death even at APAP doses within the therapeutic range. Aggravated liver injury was associated with significant neutrophil infiltration; however, lack of Ahr in myeloid cells did not protect LysM(Delta/Delta Ahr) mice from exacerbated APAP hepatotoxicity. In contrast, Alb(Delta/Delta Ahr) mice were largely protected from ITE-induced aggravated liver damage, indicating that Ahr activation in hepatocytes, but not in myeloid cells, was instrumental for disease exacerbation. Mechanistically, Ahr activation fueled hepatic accumulation of toxic APAP metabolites by up-regulating expression of the APAP-metabolizing enzyme Cyp1a2, a direct Ahr downstream target. CONCLUSIONS: Ahr activation in hepatocytes potentiates APAP-induced hepatotoxicity. Thus, individual exposition to environmental Ahr ligands might explain individual sensitivity to hyperacute liver failure.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 123-08-0 is helpful to your research. HPLC of Formula: https://www.ambeed.com/products/123-08-0.html.

The equilibrium acidity scale (pK(a) scale) in acetonitrile has been supplemented by numerous new compounds and new Delta pK(a) measurements. It now contains altogether 231 acids – over twice more than published previously – linked by 569 Delta pK(a) measurements and spans between the pK(a) values of hydrogen iodide (2.8) and indole (32.57), covering close to 30 orders of magnitude. Measurement results acquired over the last 15 years were added to the scale and new least-squares treatment was carried out. The treatment yielded revised pK(a) values for the compounds published previously, with the root mean square difference between revised and previous values 0.04, demonstrating very good stability of the scale. Correlation equations were developed for estimating pK(a) values for the studied types of compounds in water, DMSO, DMF, and 1,2-dichloroethane on the basis of pK(a) values in acetonitrile. These equations enable predicting pK(a) values with an average error around or less than 1 pK(a) unit, which is a sufficient accuracy for many applications. The scale is expected to be a useful tool for the widest possible research areas in organic chemistry, electrochemical power sources, catalysis, etc.

Indole-based chalcones have been identified as interesting compounds with anticancer properties. In the present study, we report the synthesis and evaluation of new 1-methoxyindole and 2-alkoxyindole chalcone hybrids as antiproliferative agents active against colorectal carcinoma cell line. Among the 19 investigated molecules, four inhibit the proliferation of colorectal cancer cells HCT-116 with IC50 values <8 mu M and display low cytotoxicity to fibroblast cell line 3T3. The UV-visible, CD and fluorescence competitive displacement assays with ethidium bromide and Hoechst 33258 performed with two active chalcones demonstrated that investigated chalcones interact with calf thymus (CT) DNA through the groove binding mode. Likewise, the quenching interaction of chalcones with bovine serum albumin (BSA) was studied in vitro under optimal physiological condition (pH = 7.4). The Stern-Volmer constant for chalcone-BSA system was found in the range of 10(5) M-1. Application of 123-08-0, The reactant in an enzyme-catalyzed reaction is called a substrate.
