Hassan, Muhammad Murtaza’s team published research in Journal of Medicinal Chemistry in 2020 | CAS: 21900-36-7

3-(tert-Butyl)benzoyl chloride(cas: 21900-36-7) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Name: 3-(tert-Butyl)benzoyl chloride

Hassan, Muhammad Murtaza; Israelian, Johan; Nawar, Nabanita; Ganda, Giovanni; Manaswiyoungkul, Pimyupa; Raouf, Yasir S.; Armstrong, David; Sedighi, Abootaleb; Olaoye, Olasunkanmi O.; Erdogan, Fettah; Cabral, Aaron D.; Angeles, Fabrizio; Altintas, Rabia; de Araujo, Elvin D.; Gunning, Patrick T. published their research in Journal of Medicinal Chemistry on August 13 ,2020. The article was titled 《Characterization of Conformationally Constrained Benzanilide Scaffolds for Potent and Selective HDAC8 Targeting》.Name: 3-(tert-Butyl)benzoyl chloride The article contains the following contents:

Histone deacetylases (HDACs) are an attractive therapeutic target for a variety of human diseases. Currently, all four FDA-approved HDAC-targeting drugs are nonselective, pan-HDAC inhibitors, exhibiting adverse side effects at therapeutic doses. Although selective HDAC inhibition has been proposed to mitigate toxicity, the targeted catalytic domains are highly conserved. Herein, a series of rationally designed, conformationally constrained, benzanilide foldamers which selectively bind the catalytic tunnel of HDAC8 is described. The series includes benzanilides, MMH371, MMH409, and MMH410, which exhibit potent in vitro HDAC8 activity (IC50 = 66, 23, and 66 nM, resp.) and up to 410-fold selectivity for HDAC8 over the next targeted HDAC. Exptl. and computational analyses of the benzanilide structure docked with human HDAC8 enzyme showed the adoption of a low-energy L-shaped conformer that favors HDAC8 selectivity. The conformationally constrained HDAC8 inhibitors present an alternative biol. probe for further determining the clin. utility and safety of pharmacol. knockdown of HDAC8 in diseased cells. The results came from multiple reactions, including the reaction of 3-(tert-Butyl)benzoyl chloride(cas: 21900-36-7Name: 3-(tert-Butyl)benzoyl chloride)

All complexes were about 10 to 100-fold more active than cisplatin, depending on the tested tumor cell line. For comparison purposes, the cytotoxic effects of 1-4 towards human lung fibroblasts (MRC-5) have also been tested. The late apoptosis-inducing properties of 1-4 compounds in SK-MEL-5 cells were verified 24 h incubation using annexin V-Fluorescein isothiocyanate (FITC)/propidium iodide (PI). The binding properties of the model compound 1 on human serum albumin (HSA) and calf thymus DNA (ct-DNA) have been studied using CD and fluorescence spectroscopy. Docking simulations have been carried out to gain more information about the interaction of the palladacycle and HSA.

Brown, Thomas H.’s team published research in European Journal of Medicinal Chemistry in 1988 | CAS: 7116-36-1

Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. Name: Ethyl 3-(4-chlorophenyl)propanoate However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.

Brown, Thomas H.; Blakemore, Robert C.; Durant, Graham J.; Emmett, John C.; Ganellin, C. Robin; Parsons, Michael E.; Rawlings, D. Anthony; Walker, Terence F. published their research in European Journal of Medicinal Chemistry on February 29 ,1988. The article was titled 《Isocytosine H2-receptor histamine antagonists. I. Oxmetidine and related compounds》.Name: Ethyl 3-(4-chlorophenyl)propanoate The article contains the following contents:

2-[2-(5-Methyl-4-imidazolylmethylthio)ethylamino]-4-pyrimidones I (R = H, Me, PhO, substituted benzyl, etc.; R1 = H, Me, Pr, PhCH2) were prepared via substitution of (methylthio)pyrimidinones with 5-methyl-4-[(2-aminomethyl)thiomethyl]imidazole. The model compound I (R = R1 = H) has modest H2-antagonist activity as shown by its ability to antagonize histamine-stimulated tachycardia in guinea pig right atrium in vitro and inhibit histamine-stimulated gastric acid secretion in the lumen-perfused stomach of the anesthetized rat. Investigation of the effect of substituents in the pyrimidone ring showed that suitable substitution at the 5-position gave compounds with greatly increased activity, whereas substituents at other positions in the ring were not favorable for activity. Some structure-activity and structure-toxicity correlations are discussed. The experimental part of the paper was very detailed, including the reaction process of Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1Name: Ethyl 3-(4-chlorophenyl)propanoate)

Chemical Communications (Cambridge, United Kingdom) published new progress about Halides Role: IMF (Industrial Manufacture), PREP (Preparation). 22519-64-8 belongs to class chlorides-buliding-blocks, and the molecular formula is Cl3H8InO4, Name: Indium(III) chloride tetrahydrate.

Jiang, Xiaoqing; Wu, Hongping; Yu, Hongwei; Hu, Zhanggui; Wang, Jiyang; Wu, Yicheng published the artcile< Metal halide In(Ba3Cl3F6) - a novel infrared-transparent molecular sieve constructed by halides>, Name: Indium(III) chloride tetrahydrate, the main research area is metal halide manufacture barium indium chloride fluoride mol sieve.

Mol. sieves are of increasing importance in catalysis, the oil industry, and biomedicine. Traditional mol. sieves are generally oxides that inevitably show some absorption in the mid- and far-IR range due to the vibrations of metal-oxygen bonds, which are unfavorable for the in situ observation of the reactions in mol. sieves through IR techniques. In this study, a new metal halide In[Ba3Cl3F6] has been synthesized. It exhibits a quite transparent window from 0.366 to 22 μm and good adsorption and desorption processes.

Sirenko, Oksana’s team published research in Toxicology and Applied Pharmacology in 2013-12-15 | 6055-19-2

Toxicology and Applied Pharmacology published new progress about Anti-inflammatory agents. 6055-19-2 belongs to class chlorides-buliding-blocks, and the molecular formula is C7H17Cl2N2O3P, Application In Synthesis of 6055-19-2.

Sirenko, Oksana; Cromwell, Evan F.; Crittenden, Carole; Wignall, Jessica A.; Wright, Fred A.; Rusyn, Ivan published the artcile< Assessment of beating parameters in human induced pluripotent stem cells enables quantitative in vitro screening for cardiotoxicity>, Application In Synthesis of 6055-19-2, the main research area is cardiotoxicity cardiomyocyte beating pluripotency stem cell; AUC; BMC; Calcium flux; Cardiotoxicity; DMSO; EC(50); Phenotypic screening; Predictive toxicology; area under the curve; benchmark concentration; dimethyl sulfoxide; effective concentration at 50% of the maximum response; hERG; iPSC; induced pluripotent stem cell.

Human induced pluripotent stem cell (iPSC)-derived cardiomyocytes show promise for screening during early drug development. Here, we tested a hypothesis that in vitro assessment of multiple cardiomyocyte physiol. parameters enables predictive and mechanistically-interpretable evaluation of cardiotoxicity in a high-throughput format. Human iPSC-derived cardiomyocytes were exposed for 30 min or 24 h to 131 drugs, pos. (107) and neg. (24) for in vivo cardiotoxicity, in up to 6 concentrations (3 nM to 30 uM) in 384-well plates. Fast kinetic imaging was used to monitor changes in cardiomyocyte function using intracellular Ca2+ flux readouts synchronous with beating, and cell viability. A number of physiol. parameters of cardiomyocyte beating, such as beat rate, peak shape (amplitude, width, raise, decay, etc.) and regularity were collected using automated data anal. Concentration-response profiles were evaluated using logistic modeling to derive a benchmark concentration (BMC) point-of-departure value, based on one standard deviation departure from the estimated baseline in vehicle (0.3% DMSO)-treated cells. BMC values were used for cardiotoxicity classification and ranking of compounds Beat rate and several peak shape parameters were found to be good predictors, while cell viability had poor classification accuracy. In addition, we applied the Toxicol. Prioritization Index (ToxPi) approach to integrate and display data across many collected parameters, to derive “”cardiosafety”” ranking of tested compounds Multi-parameter screening of beating profiles allows for cardiotoxicity risk assessment and identification of specific patterns defining mechanism-specific effects. These data and anal. methods may be used widely for compound screening and early safety evaluation in drug development.

Misawa, Rena’s team published research in Tetrahedron Letters in 2019-06-27 | 128-09-6

Tetrahedron Letters published new progress about Absorption. 128-09-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C4H4ClNO2, Name: 1-Chloropyrrolidine-2,5-dione.

Misawa, Rena; Matsuhashi, Chihiro; Yamaji, Minoru; Mutai, Toshiki; Yoshikawa, Isao; Houjou, Hirohiko; Noguchi, Keiichi; Maki, Shojiro; Hirano, Takashi published the artcile< Halogen-substituent effect on the spectroscopic properties of 2-phenyl-6-dimethylaminobenzothiazoles>, Name: 1-Chloropyrrolidine-2,5-dione, the main research area is halogen substituent phenyl dimethyl aminobenzothiazole spectroscopic property.

The 6-dimethylamino-2-phenylbenzothiazole (1-H) is a push-pull benzothiazole fluorophore mimicking the firefly oxyluciferin structure. We newly prepared 7-chloro and 7-bromo derivatives of 1-H and its 4-acetyl derivative (2-H), and their spectroscopic and photophys. properties were investigated. The halogenated derivatives showed the blue-shifted electronic absorption maxima and fluorescence emission maxima compared to 1-H and 2-H, resulted from the deformations of the NMe2 groups and the electron withdrawing properties of the halogen groups. In addition, the halogen substitutions accelerate intersystem crossing by heavy atom effect, resulting in a decrease in fluorescence quantum yields. Interestingly, however, the halogenated derivatives of 2-H still showed moderate fluorescence quantum yields. The halogenation effect is one of the guides to design push-pull benzothiazole fluorophores for tuning fluorescence properties.
