A domino Friedel-Crafts/nitro-Michael reaction between 4-substituted indoles and nitroethene is presented. The reaction is catalyzed by BINOL-derived phosphoric acid catalysts, and delivers the corresponding 3,4-ring-fused indoles with very good results in terms of yields and diastereo- and enantioselectivities. The tricyclic benzo[cd]indole products bear a nitro group at the right position to serve as precursors of ergot alkaloids, as demonstrated by the formal synthesis of 6,7-secoagroclavine from one of the adducts. DFT calculations suggest that the outcome of the reaction stems from the preferential evolution of a key nitronic acid intermediate through a nucleophilic addition pathway, rather than to the expected “quenching” through protonation.

A draft genome sequence of Jiangella alba YIM 61503T revealed a genome size of 7,664,864 bp arranged in 33 scaffolds. The genome was predicted to contain 7196 predicted genes, including 51 coding for RNA. Phylogenetic and comparative analyses of the draft genome of J. alba YIM 61503T with the available genomes of other Jiangella species suggested a proximal similarity between strains J. alba YIM 61503T and J. muralis DSM 45357T, while indicating a high divergence between J. gansuensis YIM 002T and other Jiangella species. The genome of J. alba YIM 61503T also revealed genes involved in indole-3-acetic acid biosynthesis and an alkylresorcinols gene cluster. Further, detection of phosphotransferase genes in the genome of all Jiangella species indicated that they can uptake and phosphorylate sugars. The presences of TreX-Z, TreS and OtsA-OtsB genes in some of the Jiangella strains also indicated a possible mechanism for their tolerance of high salinity. Besides providing new insights into its genetic features, our results suggested that J. alba YIM 61503T could be a potential strain for further genome mining studies. The release of this genome may, therefore, provide a better prospect for understanding ?evolutionary taxonomy? about this genus in future.

A highly efficient and atom economical one-pot annulation strategy for novel tetrahydrothiopyrano[3,4-b]indoles is presented. This protocol involves a Bi(OTf)3 catalyzed tandem Friedel?Crafts alkylation and intramolecular thia-Michael addition reactions to furnish target molecules in an efficient manner. The method works effectively on substrates with unprotected indoles and also it is successfully employed to make tetrahydrothiepino[3,4-b]indoles. The scaffolds synthesized are diverse and first of the kind. The reaction is practically simple with broad substrate scope and vast functional group compatibility.

The title paper discusses a mild strategy for an efficient C?C and C?S bond formation through ortho-quinone methide intermediate. A total of 29 examples (23 tetrasubstituted methanes with a quaternary carbon center and 6 triarylmethyl thioarenes) with diverse substitution patterns could be prepared in high yields (up to 82%). Use of indium triflate allowed the transformation to be carried out in an open flask without taking special care leaving water as the only by product. Control experiments revealed that the triflic acid generated in situ from indium triflate, probably through the coordination with substrate, acted as the actual catalyst for the transformation. Further this protocol can be utilized for the synthesis of promising bioactives such as CDRI-830 analogues, dihydrochromeno[2,3-b]indoles and 9-(1H-indol-3-yl)-9-phenyl-9H-xanthen-1-ol.

New carbazole- and phenylindole-based low molecular weight derivatives were synthesized and characterized. The compounds could form homogeneous amorphous materials (layers). The electron photoemission spectra of the layers of the synthesized compounds showed ionization potentials of 5.75-5.95 eV. The derivatives were tested as host materials in green and blue phosphorescent OLEDs with tris(2-phenylpyridine)iridium(III) and iridium(III)[bis(4,6- difluorophenyl)-pyridinato-N,C2?]picolinate, correspondingly, as the guests. One of the green OLEDs demonstrated current efficiency of 20.9 cd/A and power efficiency of 6.8 lm/W at 100 cd/m2. An efficient blue OLED showed a maximum brightness of 1160 cd/m2, and current efficiency of 9.4 cd/A with power efficiency of 4 lm/W at 100 cd/m2.

CD4 mimics such as YIR-821 and its derivatives are small molecules which inhibit the interaction between the Phe43 cavity of HIV-1 gp120 with host CD4, an interaction that is involved in the entry of HIV to cells. Known CD4 mimics generally possess three structural features, an aromatic ring, an oxalamide linker and a piperidine moiety. We have shown previously that introduction of a cyclohexyl group and a guanidine group into the piperidine moiety and a fluorine atom at the meta-position of the aromatic ring leads to a significant increase in the anti-HIV activity. In the current study, the effects of conformational flexibility were investigated by introduction of an indole-type group in the junction between the oxalamide linker and the aromatic moiety or by replacement of the oxalamide linker with a glycine linker. This led to the development of compounds with high anti-HIV activity, showing the importance of the junction region for the expression of high anti-HIV activity. The present data are expected to be useful in the future design of novel CD4 mimic molecules.

The dopamine oxidation product cysteinyl-dopamine has attracted attention as a contributor to the death of dopaminergic neurons in Parkinson’s disease. Treatment of cysteinyl-dopamine with hypochlorite yields an even more cytotoxic product. This product has potent redox-cycling activity and initiates production of superoxide in PC12 cells. Taurine, which scavenges hypochlorite, protects PC12 cells from cysteinyl-dopamine but not from the hypochlorite product, suggesting that the product, not cysteinyl-dopamine itself, is toxic. Furthermore, rotenone, which enhances expression of the hypochlorite-producing enzyme myeloperoxidase, increases the cytotoxicity of cysteinyl-dopamine but not of the hypochlorite product. This suggests that dopamine oxidation to cysteinyl-dopamine followed by hypochlorite-dependent conversion to a cytotoxic redox-cycling product leads to the generation of reactive oxygen species and oxidative stress and may contribute to the death of dopaminergic neurons.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. Computed Properties of C8H7NO2
