The article contains the following contents:

Uveal melanoma (UM) represents an aggressive type of cancer and currently, there is no effective treatment for this metastatic disease. In the last years, histone deacetylase inhibitors (HDACIs) have been studied as a possible therapeutic treatment for UM, alone or in association with other chemotherapeutic agents. Here we synthesized a series of new HDACIs based on the SAHA scaffold bearing an (arylidene)aminoxy moiety. Their HDAC inhibitory activity was evaluated on isolated human HDAC1, 3, 6, and 8 by fluorometric assay and their binding mode in the catalytic site of HDACs was studied by mol. docking. The most promising hit was the quinoline derivative , a nanomolar inhibitor of HDAC6, which exhibited a good antiproliferative effect on UM cell lines at micromolar concentration and a capability to modify the mRNA levels of HDAC target genes similar to that of SAHA. The experimental part of the paper was very detailed, including the reaction process of Ethyl 5-bromovalerate(cas: 14660-52-7Product Details of 14660-52-7)

M.; Kuo, Shiao-Wei. Safety of Tris(4-bromophenyl)amineThis research focused ontriphenylamine microporous polymer supercapacitor dye adsorption water treatment. The article conveys some information:

Conjugated microporous polymers CMPs have unique position among porous materials thus they are studied widely. Realistically, triphenylamine (TPA) derivatives generally possess high aromaticity, redox capabilities, high charge motilities, and outstanding electronic features, therefore designing CMPs based on TPA derivatives could result in fantastic properties. We performed one-pot coupling and polycondensation of a boronated triphenylamine derivative (TPA-3Bor) with bromobenzene (Bz-4Br) and bromopyrene (Py-4Br) derivatives to obtain two new TPA-based conjugated microporous polymers (TPA-Bz and TPA-Py CMPs, resp.). The successful synthesis of two TPA CMPs and their features were examined via Fourier transform IR (FTIR) and 13C solid state NMR spectroscopies. These two CMPs displayed attractive adsorptive properties toward the small dye mol. rhodamine B (RhB) from an aqueous solution Outstanding adsorption performance, rapid kinetics, and good reusability suggest that our CMPs could function as effective adsorbents for RhB and, perhaps, other pollutants from wastewater. Moreover, our TPA-based CMPs displayed effective and stable performance when introduced as electrodes for supercapacitors, with capacitances as high as 78 F g-1 at a c.d. of 1 A g-1 as well as high stability. This study emphasizes the importance of conjugation and planarity in the future design of such materials.

In 2022,Asfandiarov, N. L.; Muftakhov, M. V.; Rakhmeev, R. G.; Safronov, A. M.; Markova, A. V.; Pshenichnyuk, S. A. published an article in Journal of Electron Spectroscopy and Related Phenomena. The title of the article was 《Non covalent bonds in some bromo-substituted aromatic anions》.Name: 9,10-Dibromoanthracene The author mentioned the following in the article:

Four bromo-substituted derivatives of naphthalene and anthracene were studied by means of Dissociative Electron Attachment Spectroscopy. Long-lived mol. anions with lifetimes ranging from 25 to 144μs were observed in all mols. under investigation. In all cases mol. anion fragmentation is poor: only the Br- , [M-Br]- and (with very small intensity) [M-H]- species were observed, except for the case of 9,10-Br2-anthracene. It was shown that the presence of long-lived mol. anions in 1-Br- and 2-Br-naphthalene (τa = 26μs and τa = 25μs, resp.) does not contradict the fact that their dissociation rates measured by the pulse radiolysis method are fairly large (1.0 x1010 s-1 and 1.8 x1010 s-1, resp.). Scanning the potential energy surface of anions in the process of positioning a bromine anion around a polarized aromatic radical revealed the presence of a series of local min. separated by potential barriers. It is inferred that the most energetically favorable structures of the 1-Br- and 2-Br-naphthalene anions should be interpreted as complexes of the bromide anion bound to the polarized aromatic radical by non-covalent Br-H bonds. Similar local min. were found in the 9-Br- and 9,10-Br2-anthracene anions, but the energies of these structures are significantly higher than those of the “”standard”” anionic structures with a C-Br bond length of ∼1.93 Å. The EAas obtained with DFT CAM-B3LYP/6-311 +G(d,p) calculations are in acceptable agreement with the estimates made within the framework of the simple Arrhenius model from the lifetimes of mol. anions. In the experiment, the researchers used many compounds, for example, 9,10-Dibromoanthracene(cas: 523-27-3Name: 9,10-Dibromoanthracene)
