The extraction residue from Shengli lignite was sequentially dissolved with cyclohexane, benzene, methanol, ethanol, and isopropanol in an autoclave at 320 C to afford soluble portions (SPs) 1?5 (SP1-SP5) and the final residue (FR). The total yield of SP1-SP5 is ca. 55.1%. FR was subjected to ruthenium ion-catalyzed oxidation and the resulting products were isolated from the reaction mixture and esterified. Both the esterified products and SP1-SP5 were analyzed with a gas chromatograph/mass spectrometer. In total, 342 compounds were identified in SP1-SP5. They can be classified into normal alkanes, branched alkanes, alkenes, alkanedienes, arenes, alkanols, methylcycloalkanes, alkenols, alkylbenzenemethanols, arenols, anisol and substituted anisols, polymethyldihydrobenzofurans, arenofurans, dibenzofurans, ethoxymethylbenzenes, aldehydes, ketones, esters, nitrogen-containing organic compounds, sulfur-containing organic compounds, and other compounds. Among the compounds, arenols are predominant in SP1 and SP2 and the main compounds in SP3, while the main compounds in SP4 and SP5 are esters and arenes, respectively. According to the esterified products identified, the products from FR oxidation can be grouped into non-benzene ring carboxylic acids (NBCAs) and benzenepolycarboxylic acids (BPCAs). The total yield of BPCAs is much higher than that of NBCAs, suggesting that FR is rich in condensed aromatic moieties.

Constitutive androstane receptor (CAR) and pregnane X receptor (PXR) are closely related orphan nuclear receptor proteins that share several ligands and target overlapping sets of genes involved in homeostasis and all phases of drug metabolism. CAR and PXR are involved in the development of certain diseases, including diabetes, metabolic syndrome and obesity. Ligand screens for these receptors so far have typically focused on steroid hormone analogs with pharmacophore-based approaches, only to find relatively few new hits. Multiple CAR isoforms have been detected in human liver, with the most abundant being the constitutively active reference, CAR1, and the ligand-dependent isoform CAR3. It has been assumed that any compound that binds CAR1 should also activate CAR3, and so CAR3 can be used as a ligand-activated surrogate for CAR1 studies. The possibility of CAR3-specific ligands has not, so far, been addressed. To investigate the differences between CAR1, CAR3 and PXR, and to look for more CAR ligands that may be of use in quantitative structure-activity relationship (QSAR) studies, we performed a luciferase transactivation assay screen of 60 mostly non-steroid compounds. Known active compounds with different core chemistries were chosen as starting points and structural variants were rationally selected for screening. Distinct differences in agonist versus inverse agonist/antagonist effects were seen in 49 compounds that had some ligand effect on at least one receptor and 18 that had effects on all three receptors; eight were CAR1 ligands only, three were CAR3 only ligands and four affected PXR only. This work provides evidence for new CAR ligands, some of which have CAR3-specific effects, and provides observational data on CAR and PXR ligands with which to inform in silico strategies. Compounds that demonstrated unique activity on any one receptor are potentially valuable diagnostic tools for the investigation of in vivo molecular targets.

BACKGROUND AND PURPOSE Noscapine is a promising anti-tumour agent. The purpose of the present study was to describe the metabolic map and investigate the bioactivation of noscapine. EXPERIMENTAL APPROACH Ultra-performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry-based metabolomics was used to analyse the in vitro incubation mixtures, urine and faeces samples from mice treated with noscapine. Recombinant drug-metabolizing enzymes were employed to identify those involved in noscapine metabolism. Hepatic GSH levels and serum biochemistry were also carried out to determine reactive metabolites of noscapine. KEY RESULTS Several novel phase I metabolites of noscapine were detected after oral gavage of mice, including an N-demethylated metabolite, two hydroxylated metabolites, one metabolite undergoing both demethylation and cleavage of the methylenedioxy group and a bis-demethylated metabolite. Additionally, several novel glucuronides were detected, and their structures were elucidated through MS/MS fragmentology. Recombinant enzymes screening showed the involvement of several cytochromes P450, flavin-containing mono-oxygenase 1 and the UDP-glucuronosyltransferases UGT1A1, UGT1A3, UGT1A9 and UGT2B7, in noscapine metabolism. In vitro glutathione trapping revealed the existence of an ortho-quinone reactive intermediate formed through further oxidation of a catechol metabolite. However, this bioactivation process of noscapine does not occur in vivo. Similar to this result, altered glutathione levels in liver and serum biochemistry revealed no evidence of hepatic damage, thus indicating that, at least in mice, noscapine does not induce hepatotoxicity through bioactivation. CONCLUSIONS AND IMPLICATIONS A comprehensive metabolic map and bioactivation evaluation provides important information for the development of noscapine as an anti-tumour drug. Published 2012. This article is a U.S. Government work and is in the public domain in the USA.

Recent results from human clinical trials have established the critical role of HIV protease inhibitors in the treatment of acquired immune-deficiency syndrome (AIDS). However, the emergence of viral resistance, demanding treatment protocols, and adverse side effects have exposed the urgent need for a second generation of HIV protease inhibitors. The continued exploration of our hydroxylaminepentanamide (HAPA) transition-state isostere series of HIV protease inhibitors, which initially resulted in the identification of Crixivan (indinavir sulfate, MK-639, L-735,524), has now yielded MK-944a (L-756,423). This compound is potent, is selective, and competitively inhibits HIV-1 PR with a K(i) value of 0.049 nM. It stops the spread of the HIV(IIIb)-infected MT4 lymphoid cells at 25.0-50.0 nM, even in the presence of alpha1 acid glycoprotein, human serum albumin, normal human serum, or fetal bovine serum. MK-944a has a longer half-life in several animal models (rats, dogs, and monkeys) than indinavir sulfate and is currently in advanced human clinical trials.

Application of 10242-08-7, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 10242-08-7, molcular formula is C10H8O4, introducing its new discovery.

The synthesis of novel 3-aryl-2-arylamidobenzofurans has been accomplished via a Curtius rearrangement strategy in four steps from benzofuran-2-carboxylic acids. The requisite Suzuki-Miyaura cross-coupling, with benzyl 3-bromobenzofuran-2-ylcarbamate or 2-arylamido-3-bromobenzofurans, revealed an unusual reductive debromination process due to the presence of the free NH group. This dehalogenation can be suppressed by N-alkylation. DMAP is an efficient reagent for the one-pot conversion of benzyl benzofuran-2-ylcarbamates into the corresponding benzofuran-2-arylamides through aroylation, thus acting both as an acyl transfer reagent and a deprotecting agent of the Cbz group. A mechanism is postulated.

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 10242-08-7 is helpful to your research. Application of 10242-08-7

The thrombin receptor PAR-1 is activated by alpha-thrombin to stimulate cells, including platelets, through the tethered-ligand sequence SFLLRN. We have discovered a novel series of heterocycle-peptide hybrids comprised of a tripeptide segment, such as Cha-Arg-Phe, and an N-terminal heterocyclic group, many of which behave as full PAR-1 agonists. Certain compounds with an aminotriazole group, such as 4 and 16, are nearly as potent as SFLLRN-NH2 in inducing platelet aggregation. Also, some arylethenoyl ‘N-capped’ compounds, such as 52 and 57, exhibit mixed PAR-1 agonist-antagonist activity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Benzofuran-2-carboxylic acid, you can also check out more blogs about496-41-3
