Wei, Zuojun published the artcileNitrogen-Doped Graphene-Supported Iron Catalyst for Highly Chemoselective Hydrogenation of Nitroarenes, Synthetic Route of 350-30-1, the publication is ChemCatChem (2018), 10(9), 2009-2013, database is CAplus.

A nitrogen-doped graphene-supported iron catalyst was used for the first time in hydrogenation of a series of nitroarenes to give the corresponding aromatic amines ArNH₂ [Ar = Ph, 4-H₂CCNC₆H₄, 2-Cl-3-pyridyl, etc.] with excellent activity and chemoselectivity under mild reaction conditions. Physicochem. characterization of the catalyst by transmission electron microscopy, X-ray diffraction, XPS and Moessbauer spectroscopy revealed the formation of iron particles with an iron oxide core and a metallic iron shell that were coated by a few layers of nitrogen-doped graphene. The unique structure of FeN_x/C in the catalyst proved to contribute to the hydrogenation activity.

Guo, Chuangxing published the artcileStructure-based design of novel human Pin1 inhibitors (III): Optimizing affinity beyond the phosphate recognition pocket, Application In Synthesis of 51656-68-9, the publication is Bioorganic & Medicinal Chemistry Letters (2014), 24(17), 4187-4191, database is CAplus and MEDLINE.

The design of potent Pin1 inhibitors has been challenging because its active site specifically recognizes a phospho-protein epitope. The de novo design of phosphate-based Pin1 inhibitors focusing on the phosphate recognition pocket and the successful replacement of the phosphate group with a carboxylate have been previously reported. The potency of the carboxylate series is now further improved through structure-based optimization of ligand-protein interactions in the proline binding site which exploits the H-bond interactions necessary for Pin1 catalytic function. Further optimization using a focused library approach led to the discovery of low nanomolar non-phosphate small mol. Pin1 inhibitors. Structural modifications designed to improve cell permeability resulted in Pin1 inhibitors with low micromolar anti-proliferative activities against cancer cells.

Kikuchi, Haruhisa published the artcileIsolation of a Cyclic Depsipeptide, Aspergillicin F, and Synthesis of Aspergillicins with Innate Immune-Modulating Activity, Safety of 2-Chlorotrityl chloride, the publication is Journal of Natural Products (2015), 78(8), 1949-1956, database is CAplus and MEDLINE.

Innate immunity is the front line of self-defense against microbial infection. After searching for natural compounds that regulate innate immunity using an ex vivo Drosophila culture system, we identified a new cyclic depsipeptide, aspergillicin F, from the fungus Aspergillus sp., as an innate immune suppressor. The total synthesis and biol. evaluation of the aspergillicin family, including aspergillicin F, were performed, revealing that slight structural differences in the side chains of amino acid residues alter innate immunity-regulating activity.

Twenty-seven analogs of pyrazole derivatives I (R¹ = Me, Ph, allyl, tert-butyl; R² = 2-fluorophenyl, 3-chloro-4-fluorophenyl, 4-phenylazo, etc.) were synthesized and subjected to structure-activity relationship studies on inducing the triple response in Arabidopsis seedlings. The compound I (R¹ = allyl; R² = 3,4-dichlorophenyl) (II) has been found to exhibit potent activity on inducing the triple response in Arabidopsis seedlings. Compound II (10μM) induced an exaggerated apical hook in Arabidopsis seedlings. The curvature of the hook of the Arabidopsis seedlings was found to be 300 ± 23°, while ethephon (10μM), a prodrug of ethylene, and a non-chem. treated control were found to be 128 ± 19 and 58 ± 16°, resp. Compound II also exhibited potent activity on reducing stem elongation. The hypocotyl length of Arabidopsis seedlings treated with compound II (10μM) was found to be 0.25 ± 0.02 cm, while those of ethephon-treated (10μM) and treated controls were found to be 0.69 ± 0.06 and 1.15 ± 0.01 cm, resp. Compound II displayed potency inhibiting the root growth of Arabidopsis seedlings similar to that of ethephon.

Hoyerova, Klara published the artcileAuxin molecular field maps define AUX1 selectivity: many auxin herbicides are not substrates, Application of 3-Chloro-4-hydroxyphenylacetic acid, the publication is New Phytologist (2018), 217(4), 1625-1639, database is CAplus and MEDLINE.

Summary : Developmental responses to auxin are regulated by facilitated uptake and efflux, but detailed mol. understanding of the carrier proteins is incomplete. We have used pharmacol. tools to explore the chem. space that defines substrate preferences for the auxin uptake carrier AUX1. Total and partial loss-of-function aux1 mutants were assessed against wild-type for dose-dependent resistance to a range of auxins and analogs. We then developed an auxin accumulation assay with associated math. modeling to enumerate accurate IC50 values for a small library of auxin analogs. The structure activity relationship data were analyzed using mol. field analyses to create a pharmacophoric atlas of AUX1 substrates. The uptake carrier exhibits a very high level of selectivity towards small substrates including the natural indole-3-acetic acid, and the synthetic auxin 2,4-dichlorophenoxyacetic acid. No AUX1 activity was observed for herbicides based on benzoic acid (dicamba), pyridinyloxyacetic acid (triclopyr) or the 6-arylpicolinates (halauxifen), and very low affinity was found for picolinic acid-based auxins (picloram) and quinolinecarboxylic acids (quinclorac). The atlas demonstrates why some widely used auxin herbicides are not, or are very poor substrates. We list mol. descriptors for AUX1 substrates and discuss our findings in terms of herbicide resistance management.

Haney, Conor M. published the artcileDynamic covalent side-chain cross-links via intermolecular oxime or hydrazone formation from bifunctional peptides and simple organic linkers, SDS of cas: 42074-68-0, the publication is Journal of Peptide Science (2014), 20(2), 108-114, database is CAplus and MEDLINE.

Peptide cyclization via chemoselective reactions between side chains has proven a useful strategy to control folded structure. We report here a method for the synthesis of side-chain to side-chain cyclic peptides based on the intermol. reaction between a linear peptide functionalized with two aminooxy or hydrazide side chains and an organic dialdehyde linker. A family of oxime-based and hydrazone-based cyclic products is prepared in a modular and convergent fashion by combination of unprotected linear peptide precursors and various small mol. linkers in neutral aqueous buffer. The side-chain to side-chain linkages that result can alter peptide folding behavior. The dynamic covalent nature of the Schiff bases in the cyclic products can be utilized to create mixtures where product composition changes in response to exptl. conditions. Thus, a linear peptide precursor can select one organic linker from a mixture, and a cyclic product can dynamically exchange the small mol. component of the macrocycle.

Noh, U. published the artcilePhototrophic degradation of (2-Cl)-phenol by Rhodopseudomonas palustris: a pathway combining anaerobic and aerobic reactions, Quality Control of 33697-81-3, the publication is Mededelingen – Faculteit Landbouwkundige en Toegepaste Biologische Wetenschappen (Universiteit Gent) (1998), 63(4b), 1867-1872, database is CAplus.

The advantage of anaerobic degradation processes of recalcitrant aromatic compounds are relatively low production of biomass and the possibility of dehalogenation of highly chlorinated compounds Phototrophic bacteria are known for their diverse metabolism, however, there is only little information about phototrophic degradation of phenol and chlorinated aromatic compounds Newly isolated and culture collection strains of Rhodopseudomonas palustris could transform 2-chlorophenol under phototrophic conditions in the presence of a second carbon source to 3-chloro-4-hydroxyphenylacetic acid, which were identified by HPLC, GC-MS and NMR anal. Dechlorination was demonstrated by stoichiometric release of Cl^– in the culture fluid. The occurrence of 4-hydroxyphenylacetic acid has never been observed in the degradation of phenol under methanogenic or nitrate reducing conditions, where phenol is first carboxylated to benzoate or p-hydroxybenzoate prior to reduction of the aromatic ring and complete mineralization. Further degradation of 4-hydroxyphenylacetic acid by R. palustris required oxygen, presumably for mono- and dioxygenases, which catalyze the ring cleaving reaction. In continuous cultures the amount of oxygen could be kept low enough to allow further degradation of 4-hydroxyphenylacetic acid and the expression of nitrogenase. Under these conditions phenolic compounds might be mineralized to mol. hydrogen and CO₂.
