BRD4 plays a key role in the regulation of gene transcription and has been identified as an attractive target for cancer treatment. In this study, we designed 26 new compounds by modifying 3-ethyl-benzo[d]isoxazole core with sulfonamides. Most compounds exhibited potent BRD4 binding activities with ΔT_m values exceeding 6°C. Two crystal structures of N-(3-Ethyl-6-methoxybenzo[d]isoxazol-5-yl)-2methoxybenzenesulfonamide and N-(3-Ethyl-6-methoxybenzo[d]isoxazol-5-yl)-4methoxybenzenesulfonamide in complex with BRD4(1) were obtained to characterize the binding patterns.

Synthesis and properties of a mitochondrial peripheral benzodiazepine receptor conjugate was written by El Alaoui, Abdessamad;Schmidt, Frederic;Sarr, Marianne;Decaudin, Didier;Florent, Jean-Claude;Johannes, Ludger. And the article was included in ChemMedChem in 2008.Name: tert-Butyl (4-chlorophenyl)carbamate This article mentions the following:

Peripheral benzodiazepine receptors are potential targets for cancer therapeutics through the use of specific ligands such as the pro-apoptotic benzodiazepine RO5-4864. However, the poor water solubility of this compound has been a limitation to its application in vivo. Herein we describe an efficient synthesis for the conjugation, via a cleavable linker arm, of RO5-4864 to a novel tumor-delivery tool, the B-subunit of Shiga toxin (STxB). The conjugate is water soluble and specifically targets cancer cells that overexpress the glycolipid Gb3, the cellular Shiga toxin receptor that is found on several human tumors. After internalization via retrograde transport, the prodrug is cleaved inside cells to release the active principle. Delivery by STxB therefore increases in cytotoxic activity of RO5-4864 and its tumor specificity. In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6Name: tert-Butyl (4-chlorophenyl)carbamate).

And the article was included in Chemistry – A European Journal in 2020.SDS of cas: 202925-07-3 This article mentions the following:

A mild and transition-metal-free approach for the nucleophilic aromatic substitution (S_NAr) of unactivated fluoroarenes with primary aliphatic amines to form aromatic amines was reported. This reaction is facilitated by the formation of cationic fluoroarene radical intermediates in the presence of an acridinium-based organic photocatalyst under blue-light irradiation Various electron-rich and electron-neutral fluoroarenes are competent electrophiles for this transformation. A wide range of primary aliphatic amines, including amino acid esters, dipeptides and linear and branched amines are suitable nucleophiles. The synthetic utility of this protocol is demonstrated by the late-stage functionalization of several complex drug mols. In the experiment, the researchers used many compounds, for example, 2-Chloro-1-fluoro-4-methoxybenzene (cas: 202925-07-3SDS of cas: 202925-07-3).

5-Alkyl-6-benzyl-2-(2-oxo-2-phenylethylsulfanyl)pyrimidin-4(3H)-ones, a Series of Anti-HIV-1 Agents of the Dihydro-alkoxy-benzyl-oxopyrimidine Family with Peculiar Structure-Activity Relationship Profile was written by Nawrozkij, Maxim B.;Rotili, Dante;Tarantino, Domenico;Botta, Giorgia;Eremiychuk, Alexandre S.;Musmuca, Ira;Ragno, Rino;Samuele, Alberta;Zanoli, Samantha;Armand-Ugon, Mercedes;Clotet-Codina, Imma;Novakov, Ivan A.;Orlinson, Boris S.;Maga, Giovanni;Este, Jose A.;Artico, Marino;Mai, Antonello. And the article was included in Journal of Medicinal Chemistry in 2008.Quality Control of 2-Chloro-6-fluorophenylacetonitrile This article mentions the following:

A series of dihydro-alkylthio-benzyl-oxopyrimidines (S-DABOs) bearing a 2-aryl-2-oxoethylsulfanyl chain at pyrimidine C2, an alkyl group at C5, and a 2,6-dichloro-, 2-chloro-6-fluoro-, and 2,6-difluoro-benzyl substitution at C6 (oxophenethyl-S-DABOs, 6-8) is here described. The new compounds showed low micromolar to low nanomolar (in one case subnanomolar) inhibitory activity against wt HIV-1. Against clin. relevant HIV-1 mutants (K103N, Y181C, and Y188L) as well as in enzyme (wt and K103N, Y181I, and L100I mutated RTs) assays, compounds carrying an ethyl/iso-Pr group at C5 and a 2,6-dichloro-/2-chloro-6-fluoro-benzyl moiety at C6 were the most potent derivatives, also characterized by low fold resistance ratio. Interestingly, the structure-activity relationship (SAR) data drawn from this DABO series are more related to HEPT than to DABO derivatives These findings were at least in part rationalized by the description of a fair superimposition between the 6-8 and TNK-651 (a HEPT analog) binding modes in both WT and Y181C RTs.

And the article was included in Separation and Purification Technology in 2018.Formula: C18H37Cl This article mentions the following:

The degradation of recalcitrant organic compounds in biol.-treated municipal solid waste leachate (MSW) was investigated using pre-ozonation in a micro bubble reactor. The effects of operating parameters such as reactor pressure, liquid phase temperature, inlet ozone concentration and ozone flow rate on micro filtration (MF) performance were studied systematically. It is demonstrated that the MF was obviously enhanced with ozonation time before 45 min and increasing inlet ozone concentration, as well as increasing ozone flow rate. Addnl., the reactor pressure and liquid phase temperature have no obvious effects on improving MF performance. And the mechanism for the enhancement of MF performance was explored through anal. of the colloids present in the leachate by SEM and organic compounds by GC/MS. The micro flocculation effect and the reduction of hydrocarbon and heterocycle compounds in the leachate by ozonation treatment were responsible for improving the MF performance. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Formula: C18H37Cl).

1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning.
