COA of Formula: C10H14N2O. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about Conformational analysis of 1-arylpiperazines and 4-arylpiperidines. Author is Dijkstra, Gerard D. H..

A conformational anal. of 1-arylpiperazines and 4-arylpiperidines is presented using mol.-mechanics and semi-empirical calculations Electronic effects of substituents on the aryl ring determine the conformational behavior of 1-arylpiperazines. Steric effects play a minor role. Electron-withdrawing substituents on the aryl moiety increase the conjugation between the anilino nitrogen lone pair and the π electrons of the aryl group and direct the orientation between the aryl and heterocycle towards the same plane. Electron-releasing substituents have the opposite effect and reduce the energy difference between a coplanar and perpendicular orientation between the rings. 4-Arylpiperidines prefer a perpendicular orientation between the rings.

Application In Synthesis of 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, is researched, Molecular C17H19N3O2S, CAS is 73590-85-9, about Whole-cell oxidation of omeprazole sulfide to enantiopure esomeprazole with Lysinibacillus sp. B71. Author is Babiak, Peter; Kyslikova, Eva; Stepanek, Vaclav; Valesova, Renata; Palyzova, Andrea; Maresova, Helena; Hajicek, Josef; Kyslik, Pavel.

Production of enantiopure esomeprazole by biocatalysis is of great demand by pharmaceutical industry. A Gram-pos. bacterium oxidizing omeprazole sulfide (5-methoxy-2-[((4-methoxy-3,5-dimethylpyridin-2-yl)methyl)thio]-1H-benzoimidazole) to (S)-sulfoxide esomeprazole (S)-5-methoxy-2-[(4-methoxy-3,5-dimethylpyridin-2-yl) methylsulfinyl]-3H-benzoimidazole was isolated from soil polluted with elemental sulfur. The strain exhibited the highest identity with the genus Lysinibacillus and catalyzed oxidation of 1a into enantiopure esomeprazole with conversion of 77% in a stirred bioreactor, fed-batch culture. No consecutive oxidation of (S)-sulfoxide to sulfone was observed during whole-cell catalysis. The unique characteristics of the catalyst provide a solid basis for further improvement and development of sustainable green bioprocess.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Wallmark, Bjorn; Brandstrom, Arne; Larsson, Hakan researched the compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole( cas:73590-85-9 ).Recommanded Product: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole.They published the article 《Evidence for acid-induced transformation of omeprazole into an active inhibitor of proton-potassium ATPase within the parietal cell》 about this compound( cas:73590-85-9 ) in Biochimica et Biophysica Acta, Biomembranes. Keywords: omeprazole ATPase inhibition parietal cell; ulcer therapy omeprazole metabolism ATPase. We’ll tell you more about this compound (cas:73590-85-9).

The chem. reactions of omeprazole (I) [73590-58-6], leading to inhibition of gastric acid secretion, were investigated. In acid buffer solutions, omeprazole was found to be labile, whereas at physiol. pH it was stable (t1/2 > 17 h at pH 7.4). The stability of omeprazole was also studied in isolated, acid producing, gastric glands under conditions where acid formation was either stimulated or inhibited. The rate of transformation of omeprazole was high (t1/2 ≈ 3 min) under stimulation. Inhibition of acid formation in the gland greatly retarded the decomposition of omeprazole (t1/2 ≈ 73 min). The time-course for inhibition of acid formation by omeprazole was parallel to that for decomposition The major product formed from omeprazole was the reduced form, H 168/22 (II) [73590-85-9]. The inhibitory action of omeprazole was shown to depend on acid-induced transformation, since no inhibition was obtained when omeprazole was incubated under neutral conditions, both in the isolated gastric mucosal- and the (H+ + K+)-ATPase  [9000-83-3] preparations Despite the fact that H 168/22 was the major product formed in the glandular preparation, it was found to be virtually inactive in both the glandular and (H+ and K+)-ATPase preparations Therefore, a model is proposed in which the inhibition of acid formation by omeprazole is mediated by a compound formed during the reduction of omeprazole to H 168/22 within the acid compartments of the parietal cell. Furthermore, mercaptans, such as β-mercaptoethanol, were found to prevent as well as reverse inhibition by omeprazole in both the glandular- and (H+ + K+)-ATPase preparations This indicates that -SH groups are most likely involved in the chem. reactions leading to inhibition of acid secretion.

Application In Synthesis of 4-(Piperazin-1-yl)phenol. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about Platinum(II) dithiocarbamate complexes [Pt(S2CNR2)Cl(PAr3)] as anticancer and DNA-damaging agents. Author is Kashif Amir, Muhammad; Hogarth, Graeme; Khan, Zaibunisa; Imran, Muhammad; Zia-ur-Rehman.

Following the fortunate discovery of cisplatin as an anticancer drug the search for new effective Pt-containing analogs with high potency but reduced side effects and resistance is of great importance. Herein, we report four new monofunctional platinum(II) dithiocarbamate complexes, [Pt(S2CNR2)Cl(PAr3)], and their activity against selected cancer cell lines. DFT-optimized structures reveal steric hindrance, similar to phenanthriplatin, from an axial C-H site of the triarylphosphine. High activity against selected cancer cell lines, MCF-7 > LU > Hepa-IcIc7, can be attributed to the axial protection offered by the aromatic C-H moiety, together with the lipophilicity and formation of bulkier and more hydrophobic DNA adducts. DNA binding, denaturing and plasmid cleavage studies demonstrate their potential to cleave DNA via electrostatic or covalent interactions. DFT and exptl. studies show the ability to replace chloride with different nucleophiles; substitution with smaller nucleophiles being fast while with larger nucleophiles is slow.

Let’s take a look at the latest research on this compound (cas:56621-48-8).

Twenty six propargylamine mycophenolate analogs were designed and synthesized from mycophenolic acid 1 employing a key step A3-coupling reaction. Their cytotoxic activity was examined against six cancer cell lines. Four compounds exhibited selective cytotoxicity towards neuroblastoma (SH-SY5Y) cancer cells and were less toxic to normal cells in comparison to the lead compound, MPA 1 and a standard drug, ellipticine. Mol. docking results suggested that compound I is fit well in the key amino acid of three proteins (CDK9, EGFR, and VEGFR-2) as targets in cancer therapy. The propargylamine mycophenolate scaffold might be a valuable starting point for development of new neuroblastoma anticancer drugs.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Direct HPLC enantioseparation of omeprazole and its chiral impurities: Application to the determination of enantiomeric purity of esomeprazole magnesium trihydrate, published in 2010-09-05, which mentions a compound: 73590-85-9, Name is 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, Molecular C17H19N3O2S, Formula: C17H19N3O2S.

Anal. and semipreparative high-performance liquid chromatog. (HPLC) enantioseparation of the proton-pump inhibitor omeprazole (OME) and its potential organic chiral impurities were accomplished on the immobilized-type Chiralpak IA chiral stationary phase (CSP) under both polar organic and normal-phase conditions. The (S)-enantiomers were isolated with a purity of >99% ee and their absolute configuration was empirically assigned by CD spectroscopy. A chemo- and enantioselective HPLC method was validated to control the enantiomeric purity of the (S)-enantiomer of OME (ESO), an active ingredient contained in drug products, in the presence of chiral and achiral related substances. The precision, linearity and accuracy of the determination of the (R)-impurity as well as the recovery of ESO from a pharmaceutical preparation were determined The proposed method uses the mixture Me tert-butylether (MtBE)-Et acetate (EA)-EtOH (EtOH)-diethylamine (DEA) 60:40:5:0.1 (volume/volume/volume/volume) as a mobile phase. In these conditions, linearity over the concentration range 0.5-25 μg/mL for (R)-enantiomer was obtained. The limits of detection and quantification were 99 and 333 ng/mL, resp. The intra and inter-day assay precision was <2% (RSD%).

Name: 4-(Piperazin-1-yl)phenol. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about Structure-Function Analysis of Phenylpiperazine Derivatives as Intestinal Permeation Enhancers. Author is Fein, Katherine C.; Lamson, Nicholas G.; Whitehead, Kathryn A..

Purpose: A major obstacle preventing oral administration of macromol. therapeutics is poor absorption across the intestinal epithelium into the bloodstream. One strategy to improve transport across this barrier is the use of chem. permeation enhancers. Several mol. families with permeation enhancing potential have been identified previously, including piperazines. In particular, 1-phenylpiperazine has been shown to enhance transepithelial transport with minimal cytotoxicity compared to similarly effective mols. To better understand how the chem. of 1-phenylpiperazine affects its utility as an intestinal permeation enhancer, this study examined a small library of 13 derivatives of 1-phenylpiperazine. Methods: The efficacy and cytotoxicity of 13 phenylpiperazine compounds were assessed in a Caco-2 model of the intestinal epithelium. Efficacy was measured using the paracellular diffusion marker calcein as well as by immunostaining and confocal imaging of Caco-2 monolayers. Results: Of the 13 derivatives, two enhanced the permeability of the fluorescent marker calcein over 100-fold. It was found that hydroxyl or primary amine substitutions on the Ph ring significantly increased toxicity, while aliphatic substitutions resulted in efficacy and toxicity profiles comparable to 1-phenylpiperazine. Conclusions: Several potent derivatives, including 1-methyl-4-phenylpiperazine and 1-(4-methylphenyl)piperazine, displayed lower toxicity than 1-phenylpiperazine, suggesting promise in future applications.

The very potent gastric antisecretory agent omeprazole (I) [73590-58-6], presently under clin. evaluation, has been shown to act via inhibition of the gastric H+, K+-ATPase, the enzyme responsible for pumping of protons into the stomach. I needs acid activation to become an active inhibitor. A tetracyclic sulfenamide (II) was isolated from the acid decomposition of I. This sulfenamide, or, alternatively, the corresponding sulfenic acid, an unstable, probable intermediate in the sulfenamide formation, is the active inhibitor formed in vivo from omeprazole.
