Vetter, Walter published the artcileIdentification and quantification of new polybrominated di-methoxybiphenyls (PBDMBS) in marine mammals from Australia, Recommanded Product: Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, the publication is Organohalogen Compounds (2008), 2388-2391, database is CAplus.

This study aims to verify the hypothesis by the photolytical debromination as well as synthesis of dibromo and tribromo congeners related to 2,2′-diMeO-BB 80, followed by the screening of these products in environmental samples. Using the authentic standard of 2,2′-diMeO-BB 80, it was for the first time possible to quantify residues of 2,2′-diMeO-BB 80 in blubber of dolphins and cetaceans from Australia. Moreover, the calibrated solution of lower BDMBs offered the opportunity to determine these debromination products of 2,2′-diMeO-BB 80 as well. The concentrations of the 2,2′-diMeO-BB 80 related BDMBs were 0.43-1.5% of 2,2′-diMeO-BB 80.

Arai, Ryota published the artcileReversible photoinduced change in molecular ordering of diarylethene derivatives at a solution-HOPG interface, SDS of cas: 111865-47-5, the publication is Journal of the American Chemical Society (2008), 130(29), 9371-9379, database is CAplus and MEDLINE.

A diarylethene-pyrene diad and a diarylethene-pyrene-diarylethene triad were synthesized to investigate the photoinduced two-dimensional ordering change at a solution-HOPG interface. The mol. arrangements were detected by STM. The different photochromic isomers showed different orderings reflecting the differences in their mol. structures. For the diarylethene-pyrene-diarylethene triad, a new ordering appeared upon irradiation with UV light and returned to the original ordering upon subsequent irradiation with visible light. The new arrangement was assigned to the ordering of the closed-closed isomers based on the images of the isolated open- and closed-isomers. The relationship between the nature of the two-dimensional ordering and the mol. structure is discussed.

Oka, Hiroyuki published the artcileSynthesis and characterization of poly(1,3-phenylene)-based polyradicals carrying cyclic aminoxyls, SDS of cas: 111865-47-5, the publication is Journal of Materials Chemistry (2001), 11(5), 1364-1369, database is CAplus.

The synthesis and magnetic properties of poly(2,2,4,4-tetramethyl-N-yloxy-1,4-dihydro-2H-3,1-benzoxazine-6,8-diyl-1,3-phenylene) (4) are described. Polyradical 4 was prepared by the Pd-catalyzed cross-coupling reaction of 6,8-dibromo-2,2,4,4-tetramethyl-1,4-dihydro-2H-3,1-benzoxazine and bis(trimethylene) 1,3-phenylenediboronate, followed by oxidation with m-chloroperoxybenzoic acid. The number average mol. weights of 4 determined by SEC (size exclusion chromatog.) were ∼4120 (15 repeating units), and the spin concentrations determined by EPR were up to 0.75 spin per repeating unit. The EPR spectrum of 4 in a toluene glass matrix showed the ΔM_s = 2 forbidden transition at g = 4.0. A Curie plot of the ΔM_s = 2 signal intensity vs. 1/T gave a straight line, suggesting that the polyradical is in a triplet ground state or a nearly degenerate singlet-triplet state.

Kamachi, Hiroaki published the artcileStructure-activity studies on the side chain of a simplified analog of aplysiatoxin (aplog-1) with anti-proliferative activity, Synthetic Route of 111865-47-5, the publication is Bioorganic & Medicinal Chemistry (2013), 21(10), 2695-2702, database is CAplus and MEDLINE.

We have recently developed a simplified analog of aplysiatoxin (aplog-1) as an activator of protein kinase C (PKC) with anti-proliferative activity like bryostatin 1. To identify sites in aplog-1 that could be readily modified to optimize therapeutic performance and to develop a mol. probe for examining the analog’s mode of action, substituent effects on the phenol ring were systematically examined Whereas hydrophilic acetamido derivatives were less active than aplog-1 in inhibiting cancer cell growth and binding to PKCδ, introduction of hydrophobic bromine and iodine atoms enhanced both biol. activities. The anti-proliferative activity was found to correlate closely with mol. hydrophobicity, and maximal activity was observed at a log P value of 4.0-4.5. An induction test with Epstein-Barr virus early antigen demonstrated that these derivatives have less tumor-promoting activity in vitro than aplog-1 regardless of the hydrophobicity of their substituents. These results would facilitate rapid preparation of mol. probes to examine the mechanism of the unique biol. activities of aplog-1.

Uchikawa, Yuki published the artcileSynthesis and demethylation of 4,22-dimethoxy[2.10]metacyclophan-1-yne with BBr₃ to afford a novel [10](2,9)-5a,11a-benzofuro-5a-bora-11-bromochromenophane, Category: bromides-buliding-blocks, the publication is Canadian Journal of Chemistry (2012), 90(5), 441-449, database is CAplus.

4,22-Dimethoxy[2.10]metacyclophan-1-yne was prepared by bromination of [2.10]metacyclophan-1-ene followed by the dehydrobromination of the bromine adduct with KOBu-t. Treatment of 4,22-Dimethoxy[2.10]metacyclophan-1-yne with BBr₃ in CH₂Cl₂ at room temperature led to the demethylation and a successive intramol. cyclization reaction to afford a novel [10](2,9)-5a,11a-benzofuro-5a-11-bromochromenophane in good yield. Similar treatment of a mixture of the corresponding meso- and dl-1,2-dibromo-4,22-dimethoxy[2.10]metacyclophane with BBr₃ in CH₂Cl₂ under the same conditions described above afforded cis-4b,9b-dihydro[10]benzofuro[3,2-b]benzofuranophane in 83% yield.

Oka, Hiroyuki published the artcileSynthesis and characterization of poly(1,3-phenylene)-based polyradical carrying cyclic nitroxides observation of ferromagnetic interaction, HPLC of Formula: 111865-47-5, the publication is Polymer Journal (Tokyo) (1999), 31(11-1), 979-982, database is CAplus.

A poly(1,3-phenylene) containing cyclic nitroxide radicals which are planar in most cases, favoring extensive delocalization of unpaired electrons over the whole of radical mol. was prepared and the magnetic properties were studied. The radical containing polyphenylene was prepared by Pd-catalyzed cross-coupling of 6,8-Dibromo-2,2,4,4-tetramethyl-1H,2H,4H-3,1-benzoxazine and 2,2′-(1,3-phenylene)bis-1,3,2-Dioxaborinane, in the presence of Bu₄NCl and K₂CO₃ under N; the intermediate was oxidized by 3-chloroperoxybenzoic acid to generate the polyradical. The spin concentration of the polyradical determined by ESR was 1.61 x 1021 spins/g, corresponding to 0.75 spin per repeating unit. Spin concentration was constant in the solid state for a long time at room temperature A clear absorption peak due to the AM^s = 2 forbidden transition was observed at 5.5-60 K. The signal intensity vs. T-1 plots gives a linear relationship, indicating that the polyradical is in part at least in a triplet ground state (or both the triplet and singlet are nearly degenerated). The intramol. magnetic interaction through the n-conjugation is thus ferromagnetic.
