《Synthesis and biological evaluation of substituted amide derivatives of C4-ageratochromene dimer analog》 was written by Agarwal, Karishma; Gupta, Kratika; Sharma, Kriti; Khanka, Sonu; Singh, Shilpi; Singh, Jyoti; Trivedi, Laxmikant; Vasdev, Prema G.; Luqman, Suaib; Khan, Feroz; Singh, Divya; Gupta, Atul. Computed Properties of C7H13BrO2 And the article was included in Bioorganic & Medicinal Chemistry Letters in 2021. The article conveys some information:

Substituted amide derivatives of C4-ageratochromene dimer analog were synthesized through structural modification of precocene-I, isolated from the essential oil of Ageratum conyzoides L. The target compounds were evaluated for their bone-forming effect using osteoblast differentiation assay. Seven compounds presented good activity within 1 pM-1 nM concentration At 1 pM concentration, the most active compound (I) showed effective mineralization of osteoblast cells along with expression of osteogenic marker genes viz RUNX 2, BMP-2, and type 1 collagen (Type-1 col) without any toxicity towards osteoblast cells. Single crystal X-ray anal. of two compounds revealed that the core nucleus of these mols. bear Ph rings in a trans-stilbenoid system and had a good structural correlation with 17β-estradiol and diethylstilbestrol (DES). In-silico study about I showed its structural complementarities with the LBD of estrogen receptor (ER) which indicated possible ER-mediated activity of compounds After reading the article, we found that the author used Ethyl 5-bromovalerate(cas: 14660-52-7Computed Properties of C7H13BrO2)

Ethyl 5-bromovalerate(cas: 14660-52-7) belongs to bromides. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents.Computed Properties of C7H13BrO2

The article was titled 《Amidoxime prodrugs convert to potent cell-active multimodal inhibitors of the dengue virus protease》.Reference of 3,6-Dibromo-9H-carbazole The article contains the following contents:

The flavivirus genus of the Flaviviridae family comprises Dengue, Zika and West-Nile viruses which constitute unmet medical needs as neither appropriate antivirals nor safe vaccines are available. The dengue NS2BNS3 protease is one of the most promising validated targets for developing a dengue treatment however reported protease inhibitors suffer from toxicity and cellular inefficacy. Here we report SAR on our previously reported Zika-active carbazole scaffold, culminating in prodrug compound SP-471P (EC50 1.10μM, CC50 > 100μM) that generates SP-471 (I → II); one of the most potent, non-cytotoxic and cell-active protease inhibitors described in the dengue literature. In cell-based assays, SP-471P leads to inhibition of viral RNA replication and complete abolishment of infective viral particle production even when administered 6 h post-infection. Mechanistically, SP-471 appears to inhibit both normal intermol. protease processes and intramol. cleavage events at the NS2BNS3 junction, as well as at NS3 internal sites, all critical for virus replication. These render SP-471 a unique to date multimodal inhibitor of the dengue protease. The results came from multiple reactions, including the reaction of 3,6-Dibromo-9H-carbazole(cas: 6825-20-3Reference of 3,6-Dibromo-9H-carbazole)

Fiankor, Christian; Nyakuchena, James; Khoo, Rebecca Shu Hui; Zhang, Xu; Hu, Yuchen; Yang, Sizhuo; Huang, Jier; Zhang, Jian published their research in Journal of the American Chemical Society in 2021. The article was titled 《Symmetry-Guided Synthesis of N,N′-Bicarbazole and Porphyrin-Based Mixed-Ligand Metal-Organic Frameworks: Light Harvesting and Energy Transfer》.COA of Formula: C12H7Br2N The article contains the following contents:

In the past decades, many attempts have been made to mimic the energy transfer (EnT) in photosynthesis, a key process occurring in nature that is of fundamental significance in solar fuels and sustainable energy. Metal-organic frameworks (MOFs), an emerging class of porous crystalline materials self-assembled from organic linkers and metal or metal cluster nodes, offer an ideal platform for the exploration of directional EnT phenomena. However, placing energy donor and acceptor moieties within the same framework with an atomistic precision appears to be a major synthesis challenge. In this work, we report the design and synthesis of a highly porous and photoactive N,N′-bicarbazole- and porphyrin-based mixed-ligand MOF, namely, NPF-500-H2TCPP (NPF = Nebraska porous framework; H2TCPP = meso-tetrakis(4-carboxyphenyl)porphyrin), where the secondary ligand H2TCPP is incorporated precisely through the open metal sites of the equatorial plane of the octahedron cage resulting from the underlying (4,8) connected network of NPF-500. The efficient EnT process from N,N′-bicarbazole to porphyrin in NPF-500-H2TCPP was captured by time-resolved spectroscopy and exemplified by photocatalytic oxidation of thioanisole. These results demonstrate not only the capability of NPF-500 as the scaffold to precisely arrange the donor-acceptor assembly for the EnT process but also the potential to directly utilize the EnT process for photocatalytic applications.3,6-Dibromo-9H-carbazole(cas: 6825-20-3COA of Formula: C12H7Br2N) was used in this study.

In this article, three kinds of cellulose carbonated derivatives are synthesized by modifying cellulose with alkyl halides (namely bromopropane, benzyl bromide and bromomethyl cyclopropane) in DBU/DMSO/CO2 system.

Swart, Marthinus R.; Twigge, Linette; Erasmus, Elizabeth; Marais, Charlene; Bezuidenhoudt, Barend C. B. published an article in 2021. The article was titled 《Olefin Metathesis, p-Cresol, and the Second Generation Grubbs Catalyst: Fitting the Pieces》, and you may find the article in European Journal of Inorganic Chemistry.Name: Ethyltriphenylphosphonium bromide The information in the text is summarized as follows:

P-Cresol as additive to the Grubbs second generation catalyst (GII) allows the cross-metathesis of acrylates with prop-1-en-1-ylbenzenes under conditions that only give the prop-1-en-1-ylbenzene self-metathesis product in the absence of cresol. NMR and IR spectroscopy, MALDI-TOF MS and XPS supported the formation of a ruthenium benzylidene with hydrogen bonds between p-cresol and the chloride ligands of GII. XPS furthermore confirmed p-cresol to increase the binding energies of the GII Ru 3d5/2, 3d3/2, 3p3/2 and 3p1/2 photoelectron lines, whereas 1H NMR spectroscopy indicated the carbene carbon and hydrogen to be shielded. It is thus postulated that p-cresol allows for more facile interaction between electron-deficient compounds and the ruthenium benzylidene by decreasing the electron d. on the metal center and increasing the electron d. on the carbene. Safety: toxic thallium compounds In the part of experimental materials, we found many familiar compounds, such as Ethyltriphenylphosphonium bromide(cas: 1530-32-1Name: Ethyltriphenylphosphonium bromide)

Liu, Meifang; Liu, Li; Zhang, Zhihui; Wan, Meixiu; Guo, Huanmei; Li, Dan published an article in 2021. The article was titled 《An active catalyst system based on Pd (0) and a phosphine-based bulky ligand for the synthesis of thiophene-containing conjugated polymers》, and you may find the article in Frontiers in Chemistry (Lausanne, Switzerland).Reference of Tris(4-bromophenyl)amine The information in the text is summarized as follows:

To address the limitations of conventional Pd catalysts in the polymerization of thiophenecontaining conjugated polymers, an active catalyst system based on Pd (0) and a phosphinebased bulky ligand, L1, is explored systematically in Suzuki-Miyaura polymerizations using thiophene boronic acid pinacol ester as one of the monomers. This active catalyst is found very efficient in synthesizing a series of thiophene-containing linear and hyperbranched conjugated polymers. First, as a model example, coupling reactions between electron-rich/moderately hindered aryl or thienyl halides and thiophene boronic acid pinacol ester give excellent yields with lower catalyst loading and can be completed in a shorter reaction time relative to Pd(PPh3)4. Notably, high mol. weight thiophene-containing polymers are successfully synthesized by Suzuki-Miyaura polycondensation of 2,5-thiophene bis(boronic acid) derivatives with different dibromo- and triple bromo-substituted aromatics in 5-15 min.
