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.Tietze, Rainer; Hocke, Carsten; Loeber, Stefan; Huebner, Harald; Kuwert, Torsten; Gmeiner, Peter; Prante, Olaf researched the compound: 4-(Piperazin-1-yl)phenol( cas:56621-48-8 ).Product Details of 56621-48-8.They published the article 《Syntheses and radiofluorination of two derivatives of 5-cyano-indole as selective ligands for the dopamine subtype-4 receptor》 about this compound( cas:56621-48-8 ) in Journal of Labelled Compounds & Radiopharmaceuticals. Keywords: indolenitrile fluorine 18 preparation selective dopamine D4 radioligand; cyanoindole preparation radiofluorination selective dopamine D4 ligand. We’ll tell you more about this compound (cas:56621-48-8).

Two fluoroethoxy derivatives, namely 2-{4-[2-(2-fluoroethoxy)phenyl]piperazin-1-ylmethyl}indole-5-carbonitrile (I) and 2-{4-[4-(2-fluoroethoxy)phenyl]piperazin-1-ylmethyl}indole-5-carbonitrile (II) were synthesized as analogs of the selective D4 receptor ligand 2-[4-(4-fluorophenyl)piperazin-1-ylmethyl]indole-5-carbonitrile (FAUC 316). In vitro characterization using CHO-cells expressing different dopamine receptor subtypes gave Ki = 2.1 and 9.9 nM of I and II, resp., for the dopamine D4 subtype and displayed a 420-fold D4-selectivity over D2 receptors for II. Candidate II revealed substantially reduced α1 and serotoninergic binding affinities in comparison to I. To provide potential PET imaging probes for the dopamine D4 receptor, 18F-labeling conditions using [18F]fluoroethyl tosylate were optimized and led to radiochem. yields of 81 ± 5% (18F-I) and 47 ± 4% (18F-II) (n = 3, decay-corrected, referred to labeling agent), resp. Thus, 18F-fluoroethylation favorably at the para position of the phenylpiperazine moiety of the 5-cyanoindole framework proved to be tolerated by D4 receptors and could also be applied to alternative scaffolds to develop D4 radioligand candidates for PET with improved D4 receptor affinity and selectivity.

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: 56621-48-8, is researched, SMILESS is OC1=CC=C(N2CCNCC2)C=C1, Molecular C10H14N2OJournal, Monatshefte fuer Chemie called Dependence of mechanisms to thermodynamics in the electrochemical study of different electrophiles in the presence of some sulfur nucleophiles, Author is Beiginejad, Hadi; Rafiee, Zeinab, the main research direction is electrophile isulfur nucleophile electrochem oxidation reaction mechanism.Name: 4-(Piperazin-1-yl)phenol.

Abstract: Electrochem. study of different electrophiles in the presence of p-toluenesulfinic acid and 2-mercaptobenzothiazole as sulfur nucleophiles was investigated. Mechanistic study of the electrochem. reactions indicates that the electrochem. oxidation of some species in the presence of the sulfur groups has different mechanisms, but some other species in the presence of both sulfur nucleophiles have the same mechanism. To explain the reason for this difference, the computational study was used. Thermodn. investigation shows that when ΔGtot of the electrochem. oxidation of products are less than that of initial species, the electrochem. produced species can be oxidized during controlled-potential coulometry. The results of this work indicate that the computational study can be used to justify the reaction mechanisms. Cyclic voltammetry, linear sweep voltammetry, and controlled-potential coulometry were used to obtain the exptl. results. Also, by the use of BP86 level of theory and 6-31 + G(d,p) basis set, the theor. data were obtained.

Electrochem. oxidation of some p-aminophenol derivatives (1-5) in acidic solutions was studied both exptl. and theor. to provide insight into the influence of some factors on the hydrolysis reaction rate. The result of this work shows that the electrogenerated p-quinoneimines participate in the hydrolysis reaction and are converted to the p-benzoquinone. The hydrolysis reaction rate strongly depends on the structure of the p-aminophenols and solution’s pH. The observed homogeneous rate constants of hydrolysis (kobshyd) of p-quinoneimines were determined using digital simulation technique. The effect of different parameters such as: change of Gibbs free energy (ΔG) of the electrochem. oxidation of para-aminophenol derivatives (1-5), charge of reaction site, N-C4 bond order (Wiberg Bond Indexes, WBIs) and the nature of substituted group, on the hydrolysis rate constant were also studied. All calculations were performed using D. Functional Theory (DFT) both BP86 and B3LYP levels of theory and 6-311G (p,d) basis set. The N-C4 bond order and charge on the reaction site play significant roles in hydrolysis reaction’s rate.
