Hu, Feng published the artcile¹⁸F-labeled radiotracers for in vivo imaging of DREADD with positron emission tomography, Synthetic Route of 67914-60-7, the publication is European Journal of Medicinal Chemistry (2021), 113047, database is CAplus and MEDLINE.

Designer Receptors Exclusively Activated by Designer Drugs (DREADD) are a preclin. chemogenetic approach with clin. potential for various disorders. In vivo visualization of DREADDs has been achieved with positron emission tomog. (PET) using ¹¹C radiotracers. The objective of this study was to develop DREADD radiotracers labeled with ¹⁸F for a longer isotope half-life. A series of non-radioactive fluorinated analogs of clozapine with a wide range of in vitro binding affinities for the hM3Dq and hM4Di DREADD receptors has been synthesized for PET. Compound [¹⁸F]7b was radiolabeled via a modified ¹⁸F-deoxyfluorination protocol with a com. ruthenium reagent. [¹⁸F]7b demonstrated encouraging PET imaging properties in a DREADD hM3Dq transgenic mouse model, whereas the radiotracer uptake in the wild type mouse brain was low. [¹⁸F]7b is a promising long-lived alternative to the DREADD radiotracers [¹¹C]clozapine ([¹¹C]CLZ) and [¹¹C]deschloroclozapine ([¹¹C]DCZ).

A series of novel alkyl substituted purines were synthesized. 6-[4-(4-Propoxyphenyl)piperazin-1-yl]-9H-purine was used as the key starting material, which was synthesized via a multistep protocol and finally subjected for N-alkylation with various alkyl halides with an aim to get prospective antimicrobial agents. The structures of the novel compounds were established by substantiating them through spectral techniques like 1H-NMR, 13C-NMR, FT-IR and EI-MS. They were explored for antitubercular activity against Mycobacterium tuberculosis H37RV. Furthermore, they were checked for their antimicrobial activity concerning bacterial and fungal strains. The title compounds exhibited considerable antimicrobial activity without any significant toxicity. In silico studies depicted their good binding profile against Mycobacterium tuberculosis enoyl reductase (InhA; PDB ID: 4TZK) and Candida albicans dihydrofolate reductase (PDB ID: 1AI9). The title compounds obeyed Lipinski’s parameters and have exhibited good drug-like properties.

Kamata, Ryo published the artcileAgonistic effects of diverse xenobiotics on the constitutive androstane receptor as detected in a recombinant yeast-cell assay, Application of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone, the publication is Toxicology In Vitro (2018), 335-349, database is CAplus and MEDLINE.

The constitutive androstane receptor (CAR) is a nuclear receptor and transcription factor regulating proteins involved in xenobiotic metabolism Agonist activation of the CAR can trigger metabolic activation and toxification as well as detoxification and clearance; accordingly, xenobiotic substances acting as CAR ligands may pose a threat to human and animal health. The authors used yeast cells transduced with the human CAR and the response pathway to measure the CAR-agonistic activities of 549 synthetic or natural compounds: 216 of the tested compounds exhibited CAR-agonistic effects. Eighty-four percent of CAR-activating compounds were aromatic compounds, and >65% of these active compounds were aromatic hydrocarbons, bisphenols, monoalkyl phenols, phthalates, styrene dimers, di-Ph ethers, organochlorines, and organophosphates. The ten most potent compounds were 4-tert-octylphenol (4tOP; reference substance), 4-nonylphenol, diethylstilbestrol, benzyl Bu phthalate, 2-(4-hydroxyphenyl)-2,4,4-trimethylchroman, o,p’-DDT, methoxychlor, di-Pr phthalate, hexestrol, and octachlorostyrene. The activities of these nine non-reference compounds exceeded 10% of the 4tOP activity. Anal. of para-monoalkyl phenols suggests that branching of the alkyl group and chlorination at the ortho position raises potency. This study provides critical information for identifying the potential of CAR-mediated toxic hazards and for understanding the relevant mechanism.

Beiginejad, Hadi published the artcileEfficient factors on the hydrolysis reaction rate of some para-aminophenol derivatives in acidic pHs, Application of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone, the publication is Journal of the Electrochemical Society (2013), 160(8), H469-H473, database is CAplus.

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 (k^obs_hyd) 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.

Daneshyar, Anahita published the artcileElectrochemical synthesis of a new phosphonium betaine. Kinetic evaluation and antibacterial susceptibility, Quality Control of 67914-60-7, the publication is Electrochimica Acta (2019), 134893, database is CAplus.

Cyclic voltammetry, controlled-potential coulometry, chronoamperometry, chronocoulometry and chronopotentiometry methods were used for the electrochem. study of 1-acetyl-4-(4-hydroxyphenyl)piperazine (APIP) in the presence of PPh₃ (TPP) as a nucleophile. Electrochem. generated APIP_ox can serve as a Michael acceptor for nucleophilic attack by TPP to yield a new phosphonium betaine (APTP). The authors prepared a new product in good yield and purity by reaction of TPP with APIP_ox in an undivided cell equipped with C anode. Based on an EC mechanism, the observed homogeneous rate constant (k_obs) of the Michael addition reaction of APIP_ox with TPP were estimated by comparing the exptl. cyclic voltammograms with the digital simulated results. Also, electrochem. oxidation of APIP was studied both exptl. and theor. to provide insight into the influence of natural charge and thermodn. stability parameters on the type of chem. reaction which follows APIP_ox. The synthesized compound was evaluated for in vitro antibacterial.
