The author of the article were Relitti, Nicola; Saraswati, A. Prasanth; Chemi, Giulia; Brindisi, Margherita; Brogi, Simone; Herp, Daniel; Schmidtkunz, Karin; Saccoccia, Fulvio; Ruberti, Giovina; Ulivieri, Cristina; Vanni, Francesca; Sarno, Federica; Altucci, Lucia; Lamponi, Stefania; Jung, Manfred; Gemma, Sandra; Butini, Stefania; Campiani, Giuseppe. The article conveys some information:

The synthesis of potent and selective quinolone-based histone deacetylase 6 (HDAC6) inhibitors was reported. The quinolone moiety I and II [X= CH, N] was as an innovative bioactive cap-group for HDAC6 inhibition; its synthesis was achieved by applying a multicomponent reaction. The optimization of potency and selectivity of these products was performed by employing computational studies which leded to the discovery of the diethylaminomethyl derivatives II [X= CH, N] as the most promising hit mols. These compounds were investigated in cellular studies evaluated their anticancer effect against colon (HCT-116) and histiocytic lymphoma (U9347) cancer cells, showed good to excellent potency, leaded to tumor cell death by apoptosis induction. The small mols. I, II [X= CH, N] were able to strongly inhibit the cytoplasmic and slightly the nuclear HDAC enzymes, increased the acetylation of tubulin and of the lysine 9 and 14 of histone 3, resp. Compound II [X= CH] was also able to increase Hsp90 acetylation levels in HCT-116 cells, thus further supporting its HDAC6 inhibitory profile. Cytotoxicity and mutagenicity assays of these mols. showed a safe profile; moreover, the HPLC anal. of compound II [X= N] revealed good solubility and stability profile. The results came from multiple reactions, including the reaction of 4-Cyanobenzyl bromide(cas: 17201-43-3Application of 17201-43-3)

4-Cyanobenzyl bromide(cas: 17201-43-3) can reacts with 2H-tetrazole in the presence of KOH to yield 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile. And it may be used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile.Application of 17201-43-3

In 2007,Aly, Youssef L.; Pedersen, Erik B.; La Colla, Paolo; Loddo, Roberta published 《Synthesis and anti-HIV-1 activity of new MKC-442 analogues with an alkynyl-substituted 6-benzyl group》.Archiv der Pharmazie (Weinheim, Germany) published the findings.SDS of cas: 31938-07-5 The information in the text is summarized as follows:

Synthesis and antiviral activities are reported of a series of 6-(3-alkynyl benzyl)-substituted analogs of MKC-442 (6-benzyl-1-(ethoxymethyl)-5-isopropyluracil), a highly potent agent against HIV. The 3-alkynyl group is assumed to give a better stacking of the substituted benzyl group to reverse transcriptase (RT) and this was believed to improve antiviral activity against HIV-1. The bromo derivatives, 5-alkyl-6-(3-bromo-benzyl)-1-ethoxymethyl derivatives 7a, b and 5-alkyl-6-(3-bromobenzyl)-1-allyloxymethyl derivatives 9a, b, showed activity against HIV on the same level as their corresponding analogs 10a-d with a 3-trimethylsilylalkynylbenzyl substituent and their desilylated analogs 11a-d. However, they all showed activity against HIV-1 wild type in the range of more than 10fold lower than the one of MKC-442. Moderate activity against Y181C and Y181C + K103N mutated strains was also observed and, in some cases, they were marginally better than those found for MKC-442. A few amino-DABO and S-DABO analogs were also synthesized but they were found to be inactive against HIV.

In 2017,Ketels, Marthe; Ganiek, Maximilian A.; Weidmann, Niels; Knochel, Paul published 《Synthesis of Polyfunctional Diorganomagnesium and Diorganozinc Reagents through In Situ Trapping Halogen-Lithium Exchange of Highly Functionalized (Hetero)aryl Halides in Continuous Flow》.Angewandte Chemie, International Edition published the findings.Product Details of 105942-08-3 The information in the text is summarized as follows:

Using com. available flow reactors, di(hetero)arylmagnesium and di(hetero)arylzinc reagents containing normally incompatible functional groups such as azides, nitro groups, isothiocyanates, esters, and ketones were generated in situ by lithium-metal exchange reactions of aryl bromides or iodides such as 1-azido-4-iodobenzene with BuLi or PhLi and transmetalation with either MgCl2·LiCl or ZnCl2. Reaction of the di(hetero)arylmagnesium and di(hetero)arylzinc reagents with electrophiles such as allyl bromide, cyclopropanecarbonyl chloride, and cyclopropyl 4-fluorophenyl ketone mediated by CuCN·2 LiCl or palladium-catalyzed coupling reactions yielded (hetero)arene-containing products such as 4-N3C6H4CH2CH:CH2 in 62-85% yields. The preparation of 4-(4-bromobenzoyl)-2-fluorobenzonitrile was performed by this method on 10 mmol scale without further optimization. The experimental process involved the reaction of 4-Bromo-2-fluorobenzonitrile(cas: 105942-08-3Product Details of 105942-08-3)

In 2018,Scheidt, Felix; Schaefer, Michael; Sarie, Jerome C.; Daniliuc, Constantin G.; Molloy, John J.; Gilmour, Ryan published 《Enantioselective, Catalytic Vicinal Difluorination of Alkenes》.Angewandte Chemie, International Edition published the findings.SDS of cas: 105942-08-3 The information in the text is summarized as follows:

An efficient method was developed for the synthesis of 1,2-difluoroethyl arenes ArCH(F)CH2F [Ar = 3-CNC6H4, 4-O2NC6H4, 2-SO2MeC6H4, etc.] via enantioselective II/IIII catalytic vicinal difluorination of terminal alkenes using novel C2-sym. resorcinol derivative Catalyst turnover via in situ generation of an ArIIIIF2 species was enabled by Selectfluor oxidation and addition of an inexpensive HF-amine complex. The HF:amine ratio employed in this process provided a handle for regioselective orthogonality as a function of Bronsted acidity. Selectivity reversal from the 1,1-difluorination pathway (geminal) to the desired 1,2-difluorination (vicinal) was disclosed (>20:1 in both directions). An achiral variant of the reaction was also presented using p-iodotoluene (up to >95 % yield). In the part of experimental materials, we found many familiar compounds, such as 4-Bromo-2-fluorobenzonitrile(cas: 105942-08-3SDS of cas: 105942-08-3)
