Roemer, Max;Goncales, Vinicius R.;Keaveney, Sinead T.;Pernik, Indrek;Lian, Jiaxin;Downes, James;Gooding, J. Justin;Messerle, Barbara A. research published 《 Carbon supported hybrid catalysts for controlled product selectivity in the hydrosilylation of alkynes》, the research content is summarized as follows. A series of Rh- and Ir-hybrid catalysts with varying tether lengths has been prepared by immobilization of Rh^I, Rh^III and Ir^III complexes on carbon black via radical grafting. The performance of the different catalysts was assessed for the hydrosilylation of phenylacetylene with Et₃SiH. The efficiency of the catalysts was dependent on the length of the tethers to the surface. The Rh^III– and Ir^III hybrids afforded the β(Z)-vinylsilanes, as observed for the analogous homogeneous Rh^III catalyst. No distinct product selectivity was observed when using the homogeneous Rh^I precursors as catalysts. However, on using the Rh^III hybrid catalysts derived from the Rh^I precursors to promote hydrosilylation, the major products were the α-vinylsilanes and the origin of the difference in reactivity was found to be a chem. modification of the catalysts during immobilization. Substrate scope is demonstrated for a number of alkynes, and feasible mechanisms supported by DFT calculations are proposed.

Rojas-Prats, Elisa;Martinez-Gonzalez, Loreto;Gonzalo-Consuegra, Claudia;Liachko, Nicole F.;Perez, Concepcion;Ramirez, David;Kraemer, Brian C.;Martin-Requero, Angeles;Perez, Daniel I.;Gil, Carmen;de Lago, Eva;Martinez, Ana research published 《 Targeting nuclear protein TDP-43 by cell division cycle kinase 7 inhibitors: A new therapeutic approach for amyotrophic lateral sclerosis》, the research content is summarized as follows. Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with no known cure. Aggregates of the nuclear protein TDP-43 have been recognized as a hallmark of proteinopathy in both familial and sporadic cases of ALS. Post-translational modifications of this protein, include hyperphosphorylation, cause disruption of TDP-43 homeostasis and as a consequence, promotion of its neurotoxicity. Among the kinases involved in these changes, cell division cycle kinase 7 (CDC7) plays an important role by directly phosphorylating TDP-43. In the present manuscript the discovery, synthesis, and optimization of a new family of selective and ATP-competitive CDC7 inhibitors based on 6-mercaptopurine scaffold are described. Moreover, we demonstrate the ability of these inhibitors to reduce TDP-43 phosphorylation in both cell cultures and transgenic animal models such as C. elegans and Prp-hTDP43 (A315T) mice. Altogether, the compounds described here may be useful as versatile tools to explore the role of CDC7 in TDP-43 phosphorylation and also as new drug candidates for the future development of ALS therapies.

Rudbari, Hadi Amiri;Saadati, Arezoo;Aryaeifar, Mahnaz;Blacque, Olivier;Correia, Isabel;Islam, Mohammad Khairul;Woschko, Dennis;Janiak, Christoph;Enamullah, Mohammed research published 《 Pseudotetrahedral Zn(II)-(R or S)-dihalogen-salicylaldiminato complexes with Λ- or Δ-chirality induction at-metal》, the research content is summarized as follows. Reactions of enantiopure (S or R)-N-1-(phenyl)ethyl-2,4-X¹,X²-salicylaldimine (S-H or R-H; X¹, X² = dihalogen) with Zn(II)-nitrate give bis[(S or R)-N-1-(phenyl)ethyl-2,4-X¹,X²-salicylaldiminato-κ²N,O]-Zn(II), (Δ-ZnS or Λ-ZnR) with Δ/Λ-chirality induction at-metal in the C₂-sym. mols. EI-mass spectra show parent ion peaks. X-ray structures indicate that two phenolate-O and two imine-N atoms from two mols. of the Schiff bases coordinate to the Zn(II) ion in a pseudotetrahedral geometry. Structural analyses give evidence that the S- or R-ligand chirality gives only one diastereomer Δ-ZnS or Λ-ZnR in an enantiopure crystal. Gas-phase optimized structures suggest that the Δ-ZnS or Λ-ZnR diastereomers are slightly more stable than Λ-ZnS or Δ-ZnR by 1-2 kcal mol^-1. The intramol. interactions were analyzed with the Independent Gradient Model (IGM) using the program Multiwfn on the optimized structures and also indicate the diastereomeric preference of Δ-ZnS1 over Λ-ZnS1 (or Λ-ZnR1 over Δ-ZnR1). Variable time and temperature ¹H NMR spectra support the presence of only one diastereomer Λ-ZnR or Δ-ZnS in the bulk samples, backed by the simulated spectra which exhibit no diastereomerization in solution In contrast, the reported Zn(II)-(R or S)-salicylaldiminato/naphthaldiminato complexes show a diastereomeric mixture of both Δ- and Λ-forms and a Δ ⇄ Λ equilibrium in solution Electronic CD (ECD) spectra in solution display expected mirror-image relations for the (S or R)-Schiff base ligands and the (S or R)-ligated complexes. Combined analyses of exptl. and simulated ECD spectra further support the notion of diastereomeric excess of Δ-ZnS or Λ-ZnR in solution The overall results thus suggest the preservation of chirality at-Zn induced by S- or R-ligands in a solid or solution Supramol. packing analyses explore different kinds of intermol. interactions with the strongest one for X···O. Only the halogen atom in the para position is involved in these interactions with Br···O > Cl···O. Hirshfeld surface analyses also support these interactions between two mols. at a distance shorter than the sum of the van der Wall radii. Comparison of the exptl. and simulated PXRD patterns from the single-crystal x-ray structures shows a good matching and confirms the phase purity of the bulk samples.

In continuation of authors work on the synthesis of heteroleptic enantiopure Pd(II)-complexes, four mixed-ligand enantiomeric pairs of Pd(II) complexes (J1–J8), [Pd(pic) (R or S)-N-(2,3-dihydroxypropyl)-3,5-X₁,X₂-salicylaldimines]NO₃, (pic = 2-picolylamine; X₁ = X₂ = Cl, Br, I; X₁/X₂ = Br/Cl), were synthesized by the reaction of enantiopure halogen-substituted Schiff bases (R or S)-N-(2,3-dihydroxypropyl)-3,5-X₁,X₂-salicylaldimines with [Pd(pic)Cl₂] and obtained as yellow precipitates The composition and structure of the complexes were confirmed by elemental analyses, NMR (¹H and ¹³C), FT-IR spectroscopy and theor. calculations The NMR data confirmed the stability of these complexes in DMSO.

Ruffell, Katie;Smith, Frances R.;Green, Michael T.;Nicolle, Simon M.;Inman, Martyn;Lewis, William;Hayes, Christopher J.;Moody, Christopher J. research published 《 Diazophosphonates: Effective Surrogates for Diazoalkanes in Pyrazole Synthesis》, the research content is summarized as follows. Diazophosphonates, readily prepared from α-ketophosphonates by oxidation of the corresponding hydrazones in batch or in flow, are useful partners in 1,3-dipolar cycloaddition reactions to alkynes to give N-H pyrazoles, including the first intramol. examples of such a process. The phosphoryl group imbues a number of desirable properties into the diazo 1,3-dipole. The electron-withdrawing nature of the phosphoryl stabilizes the diazo compound making it easier to handle, while the ability of the phosphoryl group to migrate readily in a [1,5]-sigmatropic rearrangement enables its transfer from C to N to aromatize the initial cycloadduct, and hence its facile removal from the final pyrazole product. Overall, the diazophosphonate acts as a surrogate for the much less stable diazoalkane in cycloadditions, with the phosphoryl group playing a vital, but traceless, role. The cycloaddition proceeds more readily with alkynes bearing electron-withdrawing groups, and is regiospecific with asym. alkynes. The potential of diazophosphonates for use in bioorthogonal cycloadditions is demonstrated by their facile addition to strained alkynes.
