Novel Maleimide-type Acceptors Based on Annelated 1,4-Dithiins

Bis(tetraethylammonium) bis(2-thioxo-1,3-dithiole-4,5-dithiolato)zincate(II) 5 reacted with a range of 3,4-dichloromaleimides 4 (R=H, alkyl, aryl) to give a new annelated 1,4-dithiin system 6 in high yield.Oxidation of the thiones 6 gives the corresponding <1,3>-dithiolones 7.Cyclic voltammetry indicates that the new compounds are electron acceptors.

Prodigiosenes conjugated to tamoxifen and estradiol

We report the synthesis of the first click-appended prodigiosene conjugates. Four prodigiosene conjugates of estradiol functionalised at the 7alpha-position were prepared, as were three prodigiosene conjugates of tamoxifen. The coupling between a prodigiosene and an 11-hydroxy estradiol derivative via an ether linkage was investigated, as was the 11- and 7-functionalisation of the estradiol core. The robustness of estradiol protecting groups was severely challenged by reactions typically used to equip such frameworks for 11- and 7-functionalisation. Specifically, and important to synthesis involving estradiol, TBS, TMS and THP are not useful protecting groups for the functionalisation of this core. When the chemical features of the therapeutic agent limit the choice of protecting group (in this case, prodigiosenes bearing aryl, NH, alkenyl and ester groups), click chemistry becomes an attractive synthetic strategy. The anti-cancer activity of the seven click prodigiosene conjugates was evaluated.

Synthesis and biological activity of obatoclax derivatives as novel and potent SHP-1 agonists

Obatoclax is a linear oligopyrrole compound which antagonizes the antiapoptotic effects of the Bcl-2 family. Herein we describe the synthesis of obatoclax derivatives by replacement of the pyrrole and indole ring of obatoclax with thiophene, furan and thiazolidinedione. The in vitro cytotoxicity of the newly synthesized compounds is evaluated against hepatocellular carcinoma cells. Pyrrole and indole substituents of obatoclax analogues exhibited potent inhibition of cell growth. Among the tested compounds, 5d and 5e were active at 6.3 and 13.2 muM against PLC5 cells. Further assays confirmed a correlation between cell death, and p-STAT3 inhibition and SHP-1 activation by these analogues.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 69778-83-2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 69778-83-2, in my other articles.

Potent Bacterial Mutagens Produced by Chlorination of Simulated Poultry Chiller Water

Hypochlorite treatment of a simulated food-processing mixture produces 3,4-dichloromaleimide and 3,3-dichloro-4-(dichloromethylene)-2,5-pyrrolidinedione (C5HCl4NO2). The tetrachloro compound and two analogs, which can be synthesized from citraconic anhydride and itaconic anhydride, are direct-acting Ames mutagens in Salmonella typhimurium TA100 tester strain. These novel five-carbon cyclic imides are structurally similar to 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), the principal mutagenic compound present in paper pulp bleaching liquors. Molecular structure analysis of the mutagens was based on X-ray crystallography, 13C NMR, and mass spectrometry of synthetic chlorinated imides with identical mass spectra and gas chromatographic retention indices. The tetrachloroimide accounts for much of the mutagenicity of the dichloromethane-extractable pH 2 fraction from chlorination of a simulated food-processing system consisting of chicken frankfurters. In the Ames TA100 tester strain it has a molecular mutagenicity of 1450 revertants/ nmol without microsomal activation, making it the second most potent mutagen reported from a chlorination process.

Synthesis and studies on gem-fluorinated 2-azabicyclo[n.1.0]alkanes

Three novel amines all possessing gem-difluorocyclopropane, secondary amino group and a fused aliphatic cycle were synthesized by difluorocyclopropanation of N-Boc protected enamides. The compounds were stable when amino group was blocked by protonation or acylation, but otherwise underwent fragmentation already at the room temperature. Chemical structure, physico-chemical properties and fragmentation mechanisms of the fluorinated amines are studied in details.
