Synthesis

The synthesis of 4-amino-2,6-dibromophenol is as follows:4-Nitro-2,6-dibromophenol (2.97g, 10mmol) was dissolved in ethanol (15ml) and water (3ml), and acetic acid (1ml) was added. Then heat and stir to raise the temperature to 80°C, and add iron powder (1.68g, 30mmol) in batches. After the addition is complete, the reaction solution is kept warm for 30 minutes, heating is stopped, filtered while hot, the filtrate is concentrated under reduced pressure, then ethyl acetate and water are added to the concentrated residue to extract, the organic phases are combined and dried, filtered, and the solvent is removed under reduced pressure. The residue was finally separated by column chromatography (ethyl acetate/petroleum ether=1/3) to obtain 4-amino-2,6-dibromophenol (2.52g, 94.4% yield).

Substituted pteridinones as p90 ribosomal S6 protein kinase (RSK) inhibitors: A structure-activity study

The activity of p90 ribosomal S6 kinase 2 (RSK2) has emerged as an attractive target for cancer therapy due to its role in the regulation of diverse cellular processes, such as cell transformation and proliferation. Several pan-RSK inhibitors have been identified with BI-D1870 and the pseudo-analogs LJH685 and LJI308 being the most selective, potent, and frequently used small molecule inhibitors. We designed and synthesized a series of pteridinones and pyrimidines to evaluate the structural features of BI-D1870 that are required for RSK2 inhibition. We have identified inhibitors of RSK2 activity, evaluated their target engagement in cells, and measured their effect on cell viability and cytotoxicity in the MOLM-13 acute myeloid leukemia (AML) cell line. The results of our studies support that RSK2 inhibition can be achieved in MOLM-13 cells without potent cytotoxicity. The structure-activity data from this study will be used as a platform to develop novel RSK2 inhibitors.

Synthesis and some transformations of polybrominated quinone diazides

The reduction of polybrominated o- and p-nitrophenols with granular tin in concentrated aqueous HCl gave polybrominated aminophenols which were diazotized with sodium nitrite in concentrated sulfuric acid at 0°C to obtain polybrominated o- and p-quinone diazides. Their thermolysis with elimination of nitrogen generated ketocarbenes which reacted with acetylacetone to form insertion products at the activated methylene group. Ketocarbenes generated from o-quinone diazides reacted with typical dipolarophiles such as acetonitrile, benzonitrile, styrene, and phenylacetylene to afford the corresponding [3 + 2]-cycloaddition products.

A simple protocol for the visual discrimination of natural cyclodextrins in aqueous solution using perichromic probes

(Graph Presented) Three synthesized compounds, 4-(4-nitrostyryl)phenol, 2,6-dibromo-4-(2,4-dinitrobenzylideneamino) phenol and 2,6-dichloro-4-(2,4-dinitrobenzylideneamino)phenol, were deprotonated to generate the perichromic dyes 2b, 3b and 4b, respectively. These dyes were used as probes to investigate the micropolarity of natural cyclodextrins (CyDs) and it was observed that they interact differently with the CyDs according to the molecular structure of the dye and the diameter of the CyD. The solvatochromic bands of the dyes that interacted with the CyDs were bathochromically shifted, suggesting that the probes were transferred to the hydrophobic interior of the CyD in aqueous solution. Dyes 2b and 4b were found to be very selective for α-CyD and γ-CyD, respectively, while β- and γ-CyD changed the color of the solution of compound 3b. These dyes were then successfully used in a simple assay that allows the naked-eye discrimination of natural CyDs in aqueous solution, without the need for expensive techniques.

Efficient reducing system based on iron for conversion of nitroarenes to anilines

Reduction of nitroarenes with low solubility in EtOH-H2O to anilines easily occurs in a Fe-NH4Cl-acetone-H2O system, and treatment of the same nitroarenes with Fe-NH4Cl-EtOH-H2O hardly furnished the corresponding products. Under the reaction condition, the reducible or hydrolysable groups are not affected.
