In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Quantitative structure-hepatotoxicity assessment of series arylpiperazine-N1-substituted theobromine derivatives, published in 2020-02-29, which mentions a compound: 56621-48-8, mainly applied to arylpiperazinylalkyl theobromine preparation hepatotoxicity, Formula: C10H14N2O.

In this work series new theobromines, compounds I [R = benzyl, 4-hydroxyphenyl, bis(4-fluorophenyl)methyl, etc.; n = 3,4] with established antioxidant and antiproliferative activities were evaluated for their hepatotoxic effects on cellular and sub-cellular level. On isolated rat hepatocytes, compounds I [R = 4-hydroxyphenyl, n = 3,4] expressed lowest toxicity, while compounds I [R = bis(4-fluorophenyl)methyl, n = 3,4] showed highest toxicity. Compounds I [R = bis(4-fluorophenyl)methyl, n = 3,4] showed the most evident pro-oxidant effect in a lipid peroxidation model on rat liver microsomes, followed by compounds I [R = 4-fluorophenyl, n = 3,4], while the other compounds didn’t reveal statistically significant pro-oxidant effects. The performed quant. structure-toxicity relationship (QSTR) anal. show that increased lipophilicity of the tested compounds pos. correlates to their hepatotoxicity. Opposite, the presence in the structure of highly pos. H-atoms and strongly neg. oxygen, possibly originating from hydrogen bond donor groups, are associated with reduced hepatotoxicity.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about Conformational analysis of 1-arylpiperazines and 4-arylpiperidines.Quality Control of 4-(Piperazin-1-yl)phenol.

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.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 4-(Piperazin-1-yl)phenol( cas:56621-48-8 ) is researched.Application In Synthesis of 4-(Piperazin-1-yl)phenol.Andonova, Lily; Valkova, Iva; Zheleva-Dimitrova, Dimitrina; Georgieva, Maya; Momekov, Georgi; Zlatkov, Alexander published the article 《Synthesis of New N1 Arylpiperazine Substituted Xanthine Derivatives and Evaluation of their Antioxidant and Cytotoxic Effects》 about this compound( cas:56621-48-8 ) in Anti-Cancer Agents in Medicinal Chemistry. Keywords: xanthine arylpiperazine preparation antioxidant radical scavenger cytotoxicity human; Aralkylpiperazine; QSAR; antioxidant effect; cytotoxicity; leukemia cell SKW-3; theobromine.. Let’s learn more about this compound (cas:56621-48-8).

A series of new xanthine derivatives comprising an arylpiperazine I (R = Bn, 4-FC6H4, 2-MeOC6H4, etc.) moiety at N1 were synthesized. The cytotoxicity against human T-cell leukemia cell SKW-3, human acute myeloid leukemia HL-60 and human Bcell precursor leukemia cell REH is evaluated. The relationship between the structure and cytotoxicity of the compounds was investigated by quant. structure-activity relationship (QSAR) anal. and the important structural parameters were drawn. The purity of the substances is proven by corresponding m.ps. and elemental anal. The antioxidant activity has been evaluated by four common methods – DPPH, ABTS, FRAP and lipid peroxidation assay. The cytotoxic effects of the tested series were evaluated using the standard MTT-dye reduction assay on three tumor cell lines. The highest antioxidant activity was demonstrated by compound I (R = 4-HOC6H4). The highest cytotoxic effect was observed for compound I (R = bis(4-fluorophenyl)methyl). It was found that cytotoxicity against SKW-3 depends on the electron d. distribution in the structures. Branching of the mol. skeleton and introduction of heteroatoms like fluorine and sulfur in the structures also significantly improved the antiproliferative activity of the compounds

Author is Masih, Anup; Agnihotri, Amol K.; Srivastava, Jitendra K.; Pandey, Nidhi; Bhat, Hans R.; Singh, Udaya P..

Due to unavailability of a specific drug/vaccine to attenuate severe acute respiratory syndrome coronavirus 2, the current strategy to combat the infection has been largely dependent upon the use of anti-inflammatory drugs to control cytokines storm responsible for respiratory depression. Thus, in this study, we discovered novel pyrazole analogs as a potent nuclear factor kappa B (NF-κB) inhibitor. The compounds were assessed for NF-κB transcriptional inhibitory activity in RAW264.7 cells after stimulation with lipopolysaccharides (LPS), revealing Compound 6c as the most potent analog among the tested series. The effect of Compound 6c was further investigated on the levels of interleukin-1β, tumor necrosis factor-α, and interleukin-6 in LPS-stimulated RAW267.4 cells by enzyme immunoassay, where it causes a significant reduction in the level of these cytokines. In Western blot anal., Compound 6c also causes the inhibition of inhibitor kappa B-α and NF-κB. It was found to be snugly fitted into the inner grove of the active site of NF-κB by forming H-bonds and a nonbonded interaction with Asn28 in a docking anal.

Lead lactone-based ligands with modest affinity for muscarinic receptors were modified based on structure-activity relationship data in the literature to provide a new series of 5-substituted 4,5-dihydro-2(3H)-furanones. The modifications included the addition of various nitrogen-containing heterocycles attached to substituted and unsubstituted aromatic rings. The target compounds, e.g. I, were synthesized in modest yields and evaluated in preliminary muscarinic binding assays. A lactone-based ligand containing a diphenylmethylpiperazine moiety was identified as a nonselective muscarinic ligand with IC50 of 340 nM. The design of future ligands will be based, in part, on structure-activity data reported herein.

A Journal, Article, Research Support, Non-U.S. Gov’t, Journal of Medicinal Chemistry called Synthesis, Radiofluorination, and In Vitro Evaluation of Pyrazolo[1,5-a]pyridine-Based Dopamine D4 Receptor Ligands: Discovery of an Inverse Agonist Radioligand for PET, Author is Prante, Olaf; Tietze, Rainer; Hocke, Carsten; Loeber, Stefan; Huebner, Harald; Kuwert, Torsten; Gmeiner, Peter, which mentions a compound: 56621-48-8, SMILESS is OC1=CC=C(N2CCNCC2)C=C1, Molecular C10H14N2O, Name: 4-(Piperazin-1-yl)phenol.

A series of fluoro-substituted analogs structurally derived from the aminomethyl-substituted pyrazolo[1,5-a]pyridine lead compounds FAUC 113 and FAUC 213 were synthesized and evaluated as high-affinity D4 receptor (D4R) ligands (Ki = 1.3-28 nM). The para-fluoroethoxy-substituted derivatives I and II revealed an outstanding D4 subtype selectivity of more than 3 orders of magnitude over both congeners D2 and D3 combined with inverse agonism at D4R. The corresponding 18F-labeled radioligands revealed high serum stability in vitro and log P values of 2-3. In vitro rat brain autoradiog. showed specific binding of [18F]-II in distinct brain regions, including the gyrus dentate of the hippocampus, that were inhibited by both eticlopride (65-80%) and the selective D4R antagonist 10 (78-93%). The observed binding pattern was mainly consistent with the known D4R distribution in the rat brain. Thus, [18F]-II (FAUC F41) represents a potential radioligand for studying the D4R in vivo by positron emission tomog. (PET).
