And the article was published in ACS Omega in 2019. SDS of cas: 14660-52-7 The author mentioned the following in the article:

Herein, we describe the photocatalytic generation of nucleophilic aroyl radicals from simple aroyl chlorides as a universal and efficient cross-coupling strategy for the direct aroylation of heteroarenes. Furthermore, visible light-mediated direct alkylation of heteroarenes has also been achieved using unactivated bromoalkanes as radical precursors. These two strategies feature high functional group tolerance, exclusive regioselectivity for reaction at the more electrophilic position of heteroarenes, easily accessible substrates, and mild reaction conditions. Moreover, mechanism studies of two reactions are carried out to support our hypotheses.

Formula: C7H13BrO2 And the article was included in Steroids in 2020. The article conveys some information:

Two valuable forensic tools based on enzyme-linked immunoassays (ELISAs) for the anal. of 17α-methylated steroids were developed using haptens of stanazolol and its conjugates with biotin. Haptens containing terminal carboxylic group were conjugated to bovine serum albumin (BSA), rabbit serum albumin (RSA) or ovalbumin (OVA). Eight batches of antisera (RAbs) obtained by immunization of rabbits were tested in an indirect competitive ELISA system using immobilization of RSA conjugate (RSA/hapten) and competitor immobilization of the biotinylated conjugate (AB-ELISA) to avidin (avidin/hapten). The best results were achieved with the RAb 212 antibodies in RSA/ST-3 and avidin/ST-10 assembled variants. For the RSA/ST-3 system, an IC50 of 0.3 ng/mL and a detection limit of 0.02 ng/mL were measured. In case of avidin/ST-10 variant, IC50 was of 3.9 ng/mL and a detection limit of 0.57 ng/mL were obtained. The effect of solvent was tested as well as the stability of coated microtiter plates over four-month period. The cross-reactivity of the developed assays with other anabolic steroids was tested and high sensitivity towards 17α-methylated steroids was observed RSA/ST-3 assay showed significant cross-reactivity with 17α-methyltestosterone (81.2%), oxymetholone (30.4%), methandienone (10.0%) and Me dihydrotestosterone (7.7%). Similarly, in the avidin/ST-10 assay, 17α-methyltestosterone (34.5%), mestanolone (32.1%), oxymetholone (22.7%), methandienone (14.2%), 9-dehydromethyltestosterone (12.5%) and oxandrolone (1.2%) exhibited high cross-reactivity. The functionality of the developed systems was verified by the successful identification of a series of 17α-methylated anabolic steroids in a set of real samples including pharmaceutical preparations seized by the Police of the Czech Republic on the black market. In the experimental materials used by the author, we found Ethyl 5-bromovalerate(cas: 14660-52-7Formula: C7H13BrO2)

This study reported a new approach for the synthesis of 5-[2-(2-carboxyethyl)-3-[(E)-6-(4-methoxyphenyl)hex-5-enoxy]phenoxy]pentanoic acid I (ONO-LB-457), which was considered a highly potent and orally active LTB4 receptor antagonist. In this work, the preparation of compound I was proposed through a convergent synthesis focused on the preparation of two fragments. First, the preparation of 5-hydroxychroman-2-one from 2,6-dimethoxybenzaldehyde and malonic acid, involving a Knoevenagel reaction, followed by a reduction of the olefin and intramol. cyclization catalyzed by Lewis acid (tribromide) was achieved with an overall yield of 57%. Second, preparation of [(E)-6-(4-methoxyphenyl)hex-5-enyl] methanesulfonate from 5-bromovaleric acid involved a Wittig reaction. The desired compound I was obtained by nucleophilic substitution of [(E)-6-(4-methoxyphenyl)hex-5-enyl] methanesulfonate with Et 5-[2-(3-ethoxy-3-oxo-propyl)-3-hydroxy-phenoxy]pentanoate followed by hydrolysis, in seven steps with an overall yield of about 11%.

Epigenetic alterations found in all human cancers are promising targets for anticancer therapy. In this sense, histone deacetylase inhibitors (HDACIs) are interesting anticancer agents that play an important role in the epigenetic regulation of cancer cells. Here, we report 15 novel hydroxamic acid-based histone deacetylase inhibitors with quinazolinone core structures. Five compounds exhibited antiproliferative activity with IC50 values of 3.4-37.8μM. Compound 8 with a 2-mercaptoquinazolinone cap moiety displayed the highest antiproliferative efficacy against MCF-7 cells. For the HDAC6 target selectivity study, compound 8 displayed an IC50 value of 2.3μM, which is 29.3 times higher than those of HDAC3, HDAC4, HDAC8, and HDAC11. Western blot assay proved that compound 8 strongly inhibited tubulin acetylation, a substrate of HDAC6. Compound 8 also displayed stronger inhibition activity against HDAC11 than the control drug Belinostat. The inhibitory mechanism of action of compound 8 on HDAC enzymes was then explored using mol. docking study. The data revealed a high binding affinity (-7.92 kcal/mol) of compound 8 toward HDAC6. In addition, dock pose anal. also proved that compound 8 might serve as a potent inhibitor of HDAC11.

HPLC of Formula: 14660-52-7. The article was titled 《Modification of the electronic properties of the π-spacer of chromophores linked to calix[4]arene platform for DSSCs applications》. The information in the text is summarized as follows:

We have developed two novel dyes based on p-tert-butyl-calix[4]arene in order to evaluate their behavior as sensitizer in photovoltaic devices. These dyes consist in a difunctionalized calix[4]arene with triphenylamine (TPA)-donor, a heteroaromatic π-conjugated spacer, thiophene and benzothiadiazole-Ph ring, resp. and cyanoacetic acid as acceptor group. The effect of the π-spacer has been studied by UV-vis spectroscopy and Differential Pulse Voltammetry and the models compounds have been theor. investigated. The dye bearing phenylbenzothiadiazole results in a bathochromic shifted absorption and an adequate efficiency to transfer charge from D to A. The considerable increase of the photocurrent d. results in a better efficiency of the devices prepared with these novel dyes with respect to the p-tert-butyl-calix[4]arene derivatives bearing TPA dye. In particular, p-tert-butyl-calix[4]arene derivative based on phenylbenzothiadiazole has reached an efficiency value of 5.84% which means an increase of 33% of the efficiency over those calix[4]arene derivatives with TPA dye.
