Synthesis of a novel family of photochromic amorphous molecular materials based on dithienylethene, their photochromic properties and application for dual image formation

A novel family of photochromic amorphous molecular materials containing a dithienylethene moiety, 1-{5-[4-(di-p-tolylamino)phenyl]-2-methylthiophen-3-yl}-2- (2,5-dimethylthiophen-3-yl)-3,3,4,4,5,5-hexafluorocyclopentene, 1-{5-[4-(di-p-tolylamino)phenyl]-2-methylthiophen-3-yl}-2- (2-methylbenzo[b]thiophen-3-yl)-3, 3,4,4,5,5-hexafluorocyclopentene and 1,2-bis{5-[4-(di-p-tolylamino)phenyl]-2-methylthiophen-3-yl}-3, 3,4,4,5,5-hexafluorocyclopentene, have been designed and synthesised. These compounds, together with their photocyclised products, were found to readily form amorphous glasses with well-defined glass transition temperatures and to undergo photochromism as amorphous films as well as in solution. These compounds are characterised by high quantum yields for the photocyclisation reactions, very low quantum yields for the reverse ring-opening reactions and, hence, almost 100% fractions of the photocyclised form at the photostationary state in solution. These results suggest that the anti-parallel conformer is more populated than the parallel conformer. Optical dichroism was induced by irradiation of coloured films of the photocyclised compounds with linearly polarised red light, and dual image formation at the same location was realised by utilising this phenomenon.

Catalytic asymmetric synthesis of 1,1-disubstituted tetrahydro-beta- carbolines by phase-transfer catalyzed alkylations

Efficient catalytic asymmetric synthesis of 1,1-disubstituted tetrahydro-beta-carbolines has been achieved via asymmetric alkylation of 1-cyanotetrahydro-beta-carbolines using a binaphthyl-modified N-spiro-type chiral phase-transfer catalyst. This is a valuable example of hitherto difficult highly enantioselective alkylations at alpha-carbon of the cyano group under phase-transfer conditions.

Catalytic Deprotonative alpha-Formylation of Heteroarenes by an Amide Base Generated in Situ from Tetramethylammonium Fluoride and Tris(trimethylsilyl)amine

Heteroarene formylations in DMF solution proceed in the presence of an amide base catalyst generated in situ from tetramethylammonium fluoride (TMAF) and tris(trimethylsilyl)amine (N(TMS)3). The reaction proceeds at room temperature and has an operationally simple procedure. Various heteroarenes, including benzothiophene, thiophene, benzothiazole, oxazole, and indole derivatives, can be formylated with high functional group tolerance.

Photoredox Catalysis Enables Access to N-Functionalized 2,1-Borazaronaphthalenes

The synthesis and utilization of a class of 2,1-borazaronaphthyltrifluoroborate reagents that provide a general solution to the challenge of N-functionalization of the 2,1-borazaronaphthalene core is described. By adorning the nitrogen of this core with a trifluoroboratomethyl unit, a suite of odd-electron processes can be executed, installing motifs that would otherwise be inaccessible using a two-electron approach. In addition, this process enables rapid annulation, furnishing a heretofore unknown polycyclic B-N species.

Bacterial transformations of benzothiophene and methylbenzothiophenes

The abilities of three Pseudomonas strains to transform each of the six isomers of methylbenzothiophene was studied. These compounds would not support growth but were biotransformed in a cell suspension of one of the isolates and in cultures of the other two isolates while they grew on 1- methylnaphthalene or glucose. Sulfur-containing metabolites were identified by GC/MS and GC/FTIR, and when possible, by comparison with authentic standards. Sulfoxides and sulfones were frequently detected and were the most abundant products from 2- and 3-methylbenzothiophene. Two of the isolates oxidized the methyl groups to carboxylic acids which were abundant products from 3-, 5-, and 6-methylbenzothiophenes. Benzothiophenemethanols were often detected, but in very low amounts. 2,3-Diones were observed as metabolites of benzothiophene and those methylbenzothiophenes with a methyl group on the benzene ring. Isomers of tolyl methyl sulfoxide were observed as ring cleavage products from 6- and 7-methylbenzothiophene.

c-MYC G-quadruplex binding by the RNA polymerase I inhibitor BMH-21 and analogues revealed by a combined NMR and biochemical Approach

Background Pyridoquinazolinecarboxamides have been reported as RNA polymerase I inhibitors and represent a novel class of potential antitumor agents. BMH-21, was reported to intercalate with GC-rich rDNA, resulting in nucleolar stress as a primary mechanism of cytotoxicity. Methods The interaction of BMH-21 and analogues with DNA G-quadruplex structures was studied by NMR and molecular modelling. The cellular response was investigated in a panel of human tumor cell lines and protein expression was examined by Western Blot analysis. Results and conclusions We explored the ability of BMH-21 and its analogue 2 to bind to G-quadruplex present in the c-MYC promoter, by NMR and molecular modelling studies. We provide evidence that both compounds are not typical DNA intercalators but are effective binders of the tested G-quadruplex. The interaction with c-MYC G-quadruplex was reflected in down-regulation of c-Myc expression in human tumor cells. The inhibitory effect was almost complete in lymphoma cells SUDHL4 characterized by overexpression of c-Myc protein. This downregulation reflected an early and persistent modulation of cMyc mRNA. Given the relevance of c-MYC in regulation of ribosome biogenesis, it is conceivable that the inhibition of c-MYC contributes to the perturbation of nuclear functions and RNA polymerase I activity. Similar experiments with CX-5461, another RNA polymerase I transcription inhibitor, indicate the same behaviour in G-quadruplex stabilization. General significance Our results support the hypothesis that BMH-21 and analogue compounds share the same mechanism, i.e. G-quadruplex binding as a primary event of a cascade leading to inhibition of RNA polymerase I and apoptosis.
