Yuan, Lin’s team published research in Chinese Chemical Letters in 33 | CAS: 111-83-1

Chinese Chemical Letters published new progress about 111-83-1. 111-83-1 belongs to bromides-buliding-blocks, auxiliary class Bromide,Aliphatic hydrocarbon chain, name is 1-Bromooctane, and the molecular formula is C9H7NO3, Application of 1-Bromooctane.

Yuan, Lin published the artcileA highly active and selective chalcogen bond-mediated perchlorate channel, Application of 1-Bromooctane, the publication is Chinese Chemical Letters (2022), 33(4), 2026-2030, database is CAplus.

Artificial membrane transporters that either use chalcogen bonds to facilitate transmembrane flux of anions or show high selectivity toward perchlorate anions are rare. In this work, we report on one such novel monopeptide-based transporter system, featuring both chalcogen bonds for highly efficient anion transport and high transport selectivity toward ClO-4 anions. Structurally, these monopeptide mols. associate with each other via H-bonds to produce H-bonded 1D stack that not only one dimensionally but also directionally aligns the terminal bicyclic thiophene motifs to the same side. Functionally, these well-aligned thiophenes create a sulfur-rich transmembrane pathway, combinatorially fine-tunable to enable anions to efficiently cross the membrane in the increasing activity of Cl- < Br- < NO-3 < ClO-4via chalcogen bonds, with EC50 values of 0.75, 0.40, 0.37 and 0.093 μmol/L (0.3 mol% relative to lipid mols.), resp.

Cavieres, Jenifer’s team published research in Journal of Molecular Liquids in 351 | CAS: 111-83-1

Journal of Molecular Liquids published new progress about 111-83-1. 111-83-1 belongs to bromides-buliding-blocks, auxiliary class Bromide,Aliphatic hydrocarbon chain, name is 1-Bromooctane, and the molecular formula is C8H17Br, Recommanded Product: 1-Bromooctane.

Cavieres, Jenifer published the artcileIonanofluids based on ionic liquid mixtures, a new approach as an alternative material for solar energy storage, Recommanded Product: 1-Bromooctane, the publication is Journal of Molecular Liquids (2022), 118677, database is CAplus.

Hybrid materials based on ionic liquids (ILs) known as Ionanofluids (INFs) have shown exciting improvements in their thermophys. properties compared to their base fluids (BF). Within this group, INFs obtained using mixtures of ionic liquids as BFs have been virtually ignored until now. In this work, INFs composed of two equimolar mixtures of ILs, [Omim][PF₆] + [Odmim][PF₆] and [Omim][PF₆] + [Odmim][BF₄] as base fluids and Multiwalled Carbon Nanotubes (MWCNTs) with weight percentages of 0.04, 0.06, 0.08, and 0.1 wt% were elaborated. Furthermore, the thermophys. properties of our proposed new materials were evaluated and compared to conventional materials currently used in solar energy storage systems. It was shown that the heat capacity (Cp) reaches increases of up to 3.7 and 3.2 times that of nitrated salts and the com. fluid Therminol VP-1, which translates into a 9.4% and 284% higher thermal storage d. (E), resp., and even lower thermal diffusivity (α), which supports the preliminary idea of using these new materials for energy storage.

Wilkinson, Andrew A.’s team published research in ACS Central Science in 6 | CAS: 81216-14-0

ACS Central Science published new progress about 81216-14-0. 81216-14-0 belongs to bromides-buliding-blocks, auxiliary class Linker,PROTAC Linker, name is 7-Bromohept-1-yne, and the molecular formula is C15H14BNO4S, Recommanded Product: 7-Bromohept-1-yne.

Wilkinson, Andrew A. published the artcileSite-Selective and Rewritable Labeling of DNA through Enzymatic, Reversible, and Click Chemistries, Recommanded Product: 7-Bromohept-1-yne, the publication is ACS Central Science (2020), 6(4), 525-534, database is CAplus and MEDLINE.

Current methods for bioconjugation rely on the introduction of stable linkers that lack the required versatility to perform sequential functionalizations. However, sequential manipulations are an increasing requirement in chem. biol. because they can underpin multiple analyses of the same sample to provide a wider understanding of cell behavior. Here, we present a new method to site-selectively write, remove, and rewrite chem. functionality to a biomol., DNA in this case. Our method combines the precision and robustness of methyltransferase-directed labeling with the reversibility of acyl hydrazones and the efficiency of click chem. Underpinning the method is a new S-adenosyl-L-methionine derivative to site-selectively label DNA with a bifunctional chem. handle containing an acyl hydrazone-linker and a terminal azide. Functional tags are conjugated via the azide and can be removed (i.e., untagged) when needed at the acyl hydrazone via exchange with hydroxyl amine. The formed hydrazide-labeled DNA is a versatile intermediate that can be either rewritten to reset the original chem. handle or covalently reacted with a permanent tag. This ability to write, tag, untag, and permanently tag DNA is exploited to sequentially introduce two fluorescent dyes on DNA. Finally, we demonstrate the potential of the method by developing a protocol to sort labeled DNA using magnetic beads, with subsequent amplification of the sorted DNA sample for further anal. The presented method opens new avenues for site-selective bioconjugation and should underpin integrative approaches in chem. biol. where sequential functionalizations of the same sample are required. We present a method using MTases, acyl hydrazone, and click chem. to site-selectively tag, untag, and rewrite on DNA. Sequential labeling of DNA or sorting PCR DNA demonstrate its versatility.

Wahid, Sana’s team published research in Arabian Journal of Chemistry in 15 | CAS: 111-83-1

Arabian Journal of Chemistry published new progress about 111-83-1. 111-83-1 belongs to bromides-buliding-blocks, auxiliary class Bromide,Aliphatic hydrocarbon chain, name is 1-Bromooctane, and the molecular formula is C5H5BrN2, Recommanded Product: 1-Bromooctane.

Wahid, Sana published the artcileBiology-oriented drug synthesis of nitrofurazone derivatives: Their α-glucosidase inhibitory activity and molecular docking studies, Recommanded Product: 1-Bromooctane, the publication is Arabian Journal of Chemistry (2022), 15(6), 103806, database is CAplus.

In the present study, twenty (20) structural variants of nitrofurazone were synthesized based on BIODS (Biol.-oriented drug synthesis) approach. The structure elucidation of the synthetic mols. (1-20) was carried out using different spectroscopic techniques, and their α-glucosidase inhibitory activity was also determined The synthetic mols. 1-20 exhibited good α-glucosidase inhibition than the parent, nitrofurazone. Four compounds 2, 4, 6, and 7 showed potential inhibition against α-glucosidase with IC₅₀ values ranging between 0.63 ± 0.25-1.29 ± 0.46 μM as compared to the standard acarbose (IC₅₀ = 2.05 ± 0.41 μM). Nevertheless, compounds 15 (IC₅₀ = 0.74 ± 0.12 μM), and 19 (IC₅₀ = 0.54 ± 0.3 μM) also displayed good α-glucosidase inhibition and compound 19 was the most active compound of the series. Kinetic study of the active compounds 7 and 19 was also carried out to confirm the mode of inhibition. The binding interactions of the most active compounds within the active site of enzyme were determined by mol. docking. Moreover, mol. dynamic simulation of compound 19 was also performed in order to determine the stability of the overall complex (α-glucosidase + c19) in an explicit watery environment. The synthetic mols. were predicted as non-cytotoxic, however, seven compounds 1, 3, 4, 9, 10, 11, and 12 were predicted as carcinogenic.

Venugopalan, Vijay’s team published research in ACS Applied Electronic Materials in 4 | CAS: 111-83-1

ACS Applied Electronic Materials published new progress about 111-83-1. 111-83-1 belongs to bromides-buliding-blocks, auxiliary class Bromide,Aliphatic hydrocarbon chain, name is 1-Bromooctane, and the molecular formula is C7H11N, HPLC of Formula: 111-83-1.

Venugopalan, Vijay published the artcileInstabilities as the Origin of Large-Area Self-Assembled and Aligned Organic Semiconductor Nanocrystals, HPLC of Formula: 111-83-1, the publication is ACS Applied Electronic Materials (2022), 4(4), 1815-1822, database is CAplus.

Aligned nanocrystals of organic semiconductors (OSCs) are highly desirable for electronic devices and biomedical and photonic applications. Solution-based wet processing routes have the potential to produce aligned nanocrystals over large areas in small time frames. Herein, we demonstrate that by optimizing the hydrodynamic evaporative processes, controlled long-range crystalline assemblies of OSCs can be achieved (longest nanocrystal ~3 mm) purely through phys. processes: namely, from fingering instabilities. Self-assembly is achieved here without strong noncovalent interactions such as hydrogen-bonding interactions. Exptl. our approach involves just placing a drop of a solution on an inclined substrate. Nanocrystals with widths of 300-800 nm and lengths of millimeters (length/width aspect ratios >10⁵) are formed in less than 2-8 s. A hydrazine chemiresistive sensor based on the aligned crystalline patterns show unprecedented responsivity (~10^-6), 2 orders greater than those of stick-slip patterns. Finally, exptl. parameters that need optimization to achieve nanocrystal patterns are investigated in detail and pointers to fabricate such OSC nanocrystals are provided.
