Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 73590-85-9, is researched, SMILESS is CC1=CN=C(CSC2=NC3=CC(OC)=CC=C3N2)C(C)=C1OC, Molecular C17H19N3O2SJournal, Tetrahedron: Asymmetry called Asymmetric synthesis of esomeprazole, Author is Cotton, H.; Elebring, T.; Larsson, M.; Li, L.; Sorensen, H.; von Unge, S., the main research direction is esomeprazole asym synthesis.Formula: C17H19N3O2S.

A highly efficient synthesis of esomeprazole – the (S)-enantiomer of omeprazole – via asym. oxidation of prochiral sulfide I is described. The asym. oxidation was achieved by titanium-mediated oxidation with cumene hydroperoxide (CHP) in the presence of (S,S)-diethyl tartrate [(S,S)-DET]. The enantioselectivity was provided by preparing the titanium complex in the presence of I at an elevated temperature and/or during a prolonged preparation time and by performing the oxidation of I in the presence of an amine. An enantioselectivity of >94% ee was obtained using this method.

Product Details of 73590-85-9. 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. Compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, is researched, Molecular C17H19N3O2S, CAS is 73590-85-9, about Determination of the dissociation constants of omeprazole and its intermediate by capillary electrophoresis.

Capillary electrophoresis is the primary method for determining dissociation constants of compounds which have low solubility in H2O, which is often the case for pharmaceuticals. Potentiometric determination in these cases is difficult because of lowered sensitivity. A new method is based on measurement of ionic mobility as a function of the pH of the buffer used.

Song, Jiho; Lee, Hyun-e; Kim, Young Jin; Kim, Su Yeon; Kim, Dong-Seok; Min, Kyung Hoon published an article about the compound: 4-(Piperazin-1-yl)phenol( cas:56621-48-8,SMILESS:OC1=CC=C(N2CCNCC2)C=C1 ).Formula: C10H14N2O. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:56621-48-8) through the article.

5,6,7,8-Tetrahydro-4H-cyclohepta[d]isoxazole derivatives were synthesized and evaluated as a novel class of inhibitors for α-MSH (α-MSH) induced melanogenesis in a mouse melanoma B16F10 cell line. Three of the compounds (IC50 = 0.67 μM), (IC50 = 1.01 μM) and (IC50 = 0.99 μM) exhibited a potent inhibitory activity approx. 85- to 126-fold greater than kojic acid, a well-known potent inhibitor. A biochem. study indicates that the activity of this series should be displayed via down-regulation of the expression of tyrosinase.

A Journal, Article, Journal of Medicinal Chemistry called Repurposing the Clinically Efficacious Antifungal Agent Itraconazole as an Anticancer Chemotherapeutic, Author is Pace, Jennifer R.; DeBerardinis, Albert M.; Sail, Vibhavari; Tacheva-Grigorova, Silvia K.; Chan, Kelly A.; Tran, Raymond; Raccuia, Daniel S.; Wechsler-Reya, Robert J.; Hadden, M. Kyle, which mentions a compound: 56621-48-8, SMILESS is OC1=CC=C(N2CCNCC2)C=C1, Molecular C10H14N2O, Reference of 4-(Piperazin-1-yl)phenol.

Itraconazole (ITZ) is an FDA-approved member of the triazole class of antifungal agents. Two recent drug repurposing screens identified ITZ as a promising anticancer chemotherapeutic that inhibits both the angiogenesis and hedgehog (Hh) signaling pathways. We have synthesized and evaluated first- and second-generation ITZ analogs for their anti-Hh and antiangiogenic activities to probe more fully the structural requirements for these anticancer properties. Our overall results suggest that the triazole functionality is required for ITZ-mediated inhibition of angiogenesis but that it is not essential for inhibition of Hh signaling. The synthesis and evaluation of stereochem. defined des-triazole ITZ analogs also provides key information as to the optimal configuration around the dioxolane ring of the ITZ scaffold. Finally, the results from our studies suggest that two distinct cellular mechanisms of action govern the anticancer properties of the ITZ scaffold.

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

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.
